    Mucous retention cysts of the parotid gland are rare, and a coexistent adenoid cystic carcinoma is even an unusual occurrence. Such coexistent adenoid cystic carcinomas with mucous retention cyst of the parotid gland are difficult to diagnose clinically and, at times, stage difficulty in their management. We report a rare case of adenoid cystic carcinoma associated with mucous retention cyst of the parotid gland with its diagnostic and management dilemma in a 14-year-old adolescent girl.

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

    Adenoid cystic carcinoma of the breast is a rare neoplasm, accounting for only 0.1% of all malignant breast tumours. It is more common in women in the sixth decade of their lives and often in the sub areolar area. The clinical criteria is not specific and the radiographic examination showed a benign-appearing tumour. The preoperative diagnosis is possible with fine-needle aspiration cytology. The diagnosis is made by histological examination, presented a difficult differential diagnosis with cribriform carcinoma; so it is necessary to use histochemical or immunohistochemical techniques. The treatment is not well established. It consists of lumpectomy with radiation or mastectomy. Compared to other locations, adenoid cystic carcinoma of the breast has a favorable prognosis. Lymph node involvement or distant metastases seldom occur. The aim of our study is to describe the epidemiological, clinico pathological characteristics, the treatment and the prognosis of this rare type of breast tumour. (authors)

    Malignant tumors of the larynx are extremely rare in children and adolescents. Adenoid cystic carcinoma accounts for less than 1% of all malignant tumors in the larynx. We presented a 16-year-old girl with subglottic adenoid cystic carcinoma, whose symptoms of prolonged and exacerbating dyspnea had been attributed to asthma at another medical center. Indirect flexible and rigid laryngoscopy revealed a smooth mass in the subglottic region occupying 80% of the airway passage. The lesion was also confirmed by both CT and MRI. There was no lymphadenopathy in the neck. The patient was successfully treated by surgery and postoperative radiotherapy. Pathological staging was T4N0M0 according to the AJCC, 2003. During six years of follow-up, there was no evidence for local recurrence or regional and distant metastasis.

    Full Text Available Introcuction: Adenoid cystic carcinoma (ACC is the second most common salivary glands tumor and the most common malignant tumor of minor salivary glands and also submandibular glands; however ACC of the larynx and trachea is rare. These tumors generally present in subglottic region as smooth submucosal solid mass without ulceration. Their primary symptoms are often as respiratory problems. Materials and Methods: This study was done on a woman, 54 years, with subglottic ACC that presented with exertional dyspnea, stridor, cough and hoarseness. After confirmation of diagnosis with biopsy, the patient underwent a total laryngectomy and then postoperative radiotherapy. Conclusion: During one year follow up, the patient did not show any evidence of local recurrence or distant metastasis. Surgery with free margins in combination with postoperative radiotherapy was recommended to treat laryngeal ACC in order to obtain better survival.

    Adenoid cystic carcinoma is a malignant minor salivary gland tumor that represents laryngeal tumors. The submucosal location of laryngeal adenoid cystic carcinoma (LACC) results in delayed presentation. Here, we present the first systematic review of reported cases of LACC to determine trends in presentation, diagnostic and treatment modalities, and patient outcome. PubMed, Web of Science, MEDLINE, and EMBASE databases. A search of the above databases was done to identify articles reporting cases of LACC. The variables included in the analysis were patient demographics, presenting symptoms, tumor location, imaging, treatment, follow-up time, recurrence, and outcome. A total of 50 articles and 120 cases were included in the review. The most common presenting symptom was dyspnea (48.8%), followed by hoarseness (43.9%). LACC arose most frequently from the subglottis (56.7%). At presentation, 14.6% (13 of 89) of patients had regional disease. The average follow-up time was 54.0 months. At follow-up, distant metastasis was reported in 30 cases (33.3%). Surgery alone (43.3%) and surgery with radiotherapy (43.3%) were used most frequently and resulted in 57.1% and 55.3% of patients alive with no evidence disease at follow-up, respectively. LACC was most often located in the subglottis. Patients commonly presented with dyspnea and hoarseness. In this systematic review, surgery with radiotherapy and surgery alone were the most commonly employed treatment modalities, and both resulted in slightly more than 50% of patients alive with no evidence of disease at follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    The authors retrospectively assessed the usefulness of postoperative radiation therapy after local resection of adenoid cystic carcinoma, with emphasis on organ-conserving treatment and the cosmetic results. Between 1985 and 1995, 32 patients underwent local resection followed by postoperative radiation therapy with curative and organ-conserving intent. None of patients received any form of chemotherapy as part of their initial treatment. Radiation therapy was carried out by techniques that were appropriate for the site and extension of each tumor. The 5-year local control, disease-free, and overall survival rates of all patients were 76%, 68%, and 86%, respectively. The 5-year local control rate and disease-free survival rate of patients with microscopically positive margins were 89% and 75%, respectively, and higher than in patients with macroscopically residual disease, but no significant difference in 5-year overall survival rate was observed. The postoperative cosmetic results in 29 patients with head and neck lesions were evaluated. No difference was documented between the cosmetic results postoperatively setting and after postoperative radiotherapy, and no significant differences in cosmetic results were observed according to radiation dose. The combination of local resection with organ-conserving intent and postoperative radiation therapy provided good cosmetic results in patients with T1 or T2 lesions. Postoperative radiation therapy with smaller fractions is useful, because good local control can be achieved in patients with adenoid cystic carcinoma having microscopically positive margins without inducing any late adverse reactions. However, the number of patients was too small and the follow-up period was too short to draw any definite conclusion in regard to fraction size. A much longer follow-up study with a larger number patients will be required to accurately determine the optimal treatment intensity and duration of treatment. (K.H.)

    Full Text Available Adenoid cystic carcinoma of uterine cervix is a rare tumor. Its origin is debatable. It has a high incidence in postmenopausal women but rarely can develop in patients under 40. An association with squamous cell carcinoma has been described. We report a case of adenoid cystic carcinoma of the endocervical canal with foci of squamous cell carcinoma in a 34-year-old suffering from menorrhagia associated with blood-stained vaginal discharge. Per vaginum and per speculum examination revealed a growth. Cervical biopsy showed bits of tissue, suggesting adenoid cystic carcinoma. Patient was operated upon and uterus with cervix sent for histopathological examination. We report this case because of its rarity, particularly in young patients, with description of illustrative pathology and discussion on the histological diagnosis.

    Adenoid basal hyperplasia is an underrecognized cervical lesion, resembling adenoid basal carcinoma, except the absence of deep invasion into the stroma. We report a series of 10 cases, all extending less than 1 mm from the basement membrane. Our results support the hypothesis that adenoid basal hyperplasia arises from reserve cells of the cervix. Lesions were found close to the squamocolumnar junction, in continuity with the nearby subcolumnar reserve cells. They shared the same morphology and immunoprofile using a panel of 4 antibodies (keratin 5/6, keratin 14, keratin 7 and p63) designed to differentiate reserve cells from mature squamous cells and endocervical columnar cells. We detected no human papillomavirus infection by in situ hybridization targeting high-risk human papillomavirus, which was concordant with the absence of immunohistochemical p16 expression. We demonstrated human papillomavirus infection in 4 (80%) of 5 adenoid basal carcinoma, which is in the same range as previous studies (88%). Thus, adenoid basal hyperplasia should be distinguished from adenoid basal carcinoma because they imply different risk of human papillomavirus infection and of subsequent association with high-grade invasive carcinoma. In our series, the most reliable morphological parameters to differentiate adenoid basal hyperplasia from adenoid basal carcinoma were the depth of the lesion and the size of the lesion nests. Furthermore, squamous differentiation was rare in adenoid basal hyperplasia and constant in adenoid basal carcinoma. Finally, any mitotic activity and/or an increase of Ki67 labeling index should raise the hypothesis of adenoid basal carcinoma. Copyright © 2012 Elsevier Inc. All rights reserved.

    Adenoid cystic carcinoma (ACC) are uncommon tumors, representing about 10% to 15% of head and neck tumors. We compare the survival and control rates at our institution with those reported in the literature, and examine putative predictors of outcome. All patients registered with the tumor registry as having had ACC were identified. Demographic and survival variables were retrieved from the database. Additionally, a chart review of all patients was done to obtain specific information. Minor gland tumors were staged using the American Joint Committee on Cancer's criteria for squamous cell carcinomas in identical sites. Histopathologic variables retrieved included grade of the tumor, margins, and perineural invasion. Treatment modalities, field sizes, and radiation doses were recorded in applicable cases. An effort to retrieve archival tumor specimens for immunohistochemical analysis was undertaken. A total of 69 patients were treated for ACC from 1955 to 1999. One patient, who presented with fatal brain metastasis, was excluded from further analysis. Of the remaining 68 patients, 30 were men and 38 were women. The average age at diagnosis was 52 years, and mean follow-up was 13.2 years. Mean survival was 7.7 years. Overall survival (OS) rates at 5, 10, and 15 years were 72%, 44%, and 34%, and cause-specific survival was 83%, 71%, and 55%, respectively. Recurrence-free survival rates were 65%, 52%, and 30% at 5, 10, and 15 years, with a total of 29 of 68 (43%) eventually suffering a recurrence. Overall survival was adversely affected by advancing T and AJCC stage. Higher tumor grades were also associated with decreased OS, although the numbers compared were small. Primaries of the nasosinal region fared poorly when compared with other locations. Total recurrence-free survival, local and distant recurrence rates were distinctly better in primaries of the oral cavity/oropharynx when compared with those in other locations. Reduced distant recurrence-free survival was

    Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of the se tumors occurs in the minor salivary glands, especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic examinations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic examinations, dark-stained, small uniform ballad's cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

    Full Text Available Abstract Background Tracheal tumors are often misdiagnosed as asthma and are treated with inhaled steroids and bronchodilators without resolution. Case Presentation Here, a patient with tracheal adenoid cystic carcinoma who had been previously diagnosed with difficult asthma was reported. The possibility of the presence of localized airway obstruction was raised when the flow-volume curve suggesting fixed airway obstruction, was obtained. Conclusion The presenting case report emphasizes the fact that not all wheezes are asthma. It is critical to bear in mind that if a patient does not respond to appropriate anti-asthma therapy, localized obstructions should be ruled out before establishing the diagnosis of asthma.

    The Adenoid Cystic Carcinoma (ACC) or Cilindroma is a strange entity classified by the WHO within the carcinomas of salivary glands. It represents only 1 % of all the wicked tumours of the oral and maxillofacial region although, when making reference to the salivary glands, it constitutes 5% of the parotid, submaxilar and sublingual carcinomas, and about 50% of the smallest ones. The most frequent location is in the palatine glands and its main characteristics are: slow but persistent growth, high rates of local relapse and metastasis at distance originating the death between the first 5 and 10 years in 50-70% of the cases approximately. A case of localization is presented in sublingual gland which was first treated surgically and later with radiotherapy, obtaining good results. (author) [es

    2000-01-01

    Objective: To evaluate the CT manifestations of cephalic and cervical adenoid cystic carcinoma (ACC). Methods: Thirty-three cases of ACC were analyzed retrospectively. Of all cases, 22 cases underwent operation and 11 cases received radiotherapy. The manifestations of CT were evaluated and compared with the clinical and pathologic results. Results: Tumors originated from parotid gland (5 cases), floor of mouth (5 cases), nasal cavity and nasopharynx (5 cases), tongue (4 cases), palate (3 cases), tracheas (3 cases), submandibular gland (2 cases), tonsilla (2 cases), maxillary sinus (2 cases), and cheek (2 cases), respectively. The CT manifestations included: (1)ethmoid density in 21 cases, partial ethmoid density in 5 cases. (2)the morphology of ACC was irregular and the growth of the tumor was amorphous in 17 cases, and the margin of the tumor was vague in 20 cases. (3)ACC often grew along the nerve with infiltration, which caused destruction of the skull base in 5 cases and atrophy of mastication muscles and/or buccinator in 3 cases. Conclusion: (1)The characteristics of cephalic and cervical adenoid cystic carcinoma on CT scans were ethmoid density, infiltrated growth, growing along the nerve with infiltration, and submucous growth. Among them, the most important manifestation, which could lead to the histologic diagnosis on CT, was ethmoid density. (2)The range of ACC was usually underestimated on CT. (3)The manifestation of tumor growth along the nerve could be apparently displayed on MRI

  2. Mitochondrial mutations in adenoid cystic carcinoma of the salivary glands.

    Suhail K Mithani

    Full Text Available BACKGROUND: The MitoChip v2.0 resequencing array is an array-based technique allowing for accurate and complete sequencing of the mitochondrial genome. No studies have investigated mitochondrial mutation in salivary gland adenoid cystic carcinomas. METHODOLOGY: The entire mitochondrial genome of 22 salivary gland adenoid cystic carcinomas (ACC of salivary glands and matched leukocyte DNA was sequenced to determine the frequency and distribution of mitochondrial mutations in ACC tumors. PRINCIPAL FINDINGS: Seventeen of 22 ACCs (77% carried mitochondrial mutations, ranging in number from 1 to 37 mutations. A disproportionate number of mutations occurred in the D-loop. Twelve of 17 tumors (70.6% carried mutations resulting in amino acid changes of translated proteins. Nine of 17 tumors (52.9% with a mutation carried an amino acid changing mutation in the nicotinamide adenine dinucleotide dehydrogenase (NADH complex. CONCLUSIONS/SIGNIFICANCE: Mitochondrial mutation is frequent in salivary ACCs. The high incidence of amino acid changing mutations implicates alterations in aerobic respiration in ACC carcinogenesis. D-loop mutations are of unclear significance, but may be associated with alterations in transcription or replication.

    Full Text Available Adenoid cystic carcinoma is rare and usually arises in the salivary glands. It grows slowly, but is characterized by easy perineural invasion with local infiltration and distant metastasis. In metastatic setting, the efficacy of intravenous chemotherapy is limited. Herein, we report one male patient who had a advanced, inoperable adenoid cystic carcinoma with lung metastasis, presenting with right buccal unhealed ulcer, pain and poor intake, whose loco-regional tumors responded dramatically after intra-arterial chemotherapy and his symptoms were almost completely relieved. We also make a literature review for treatment of adenoid cystic carcinoma.

    Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

    Prasannasrinivas Suresh Deshpande

    2013-01-01

    Full Text Available Adenoid cystic carcinoma (ACC accounts for approximately 6-10% of all salivary gland tumors. Palatal minor salivary glands, parotid, and sub-mandibular glands are usually affected. Rarely, these lesions arising intraosseously have been reported. Mandible is commonly involved than maxilla. The present case is a giant ACC involving the right maxilla. A thorough clinical and radiographic evaluation was performed to assess the involvement of surrounding vital structures along with a meticulous metastatic work-up. Computed tomography showed a giant lesion in maxilla encroaching the left nasal fossa, antrum, buccal space, and oral cavity. No metastasis was noted. Histological evaluation from multiple sites showed both cribriform and solid patterns. Radiotherapy was given as patient did not comply for surgery. Though central ACC is extremely rare, especially in maxilla, it should be included in the differentials for lesions in maxilla. A prompt diagnosis with treatment and long-term follow-up is advised in such cases.

    1996-01-01

    Purpose: To examine the efficacy of fast neutron radiotherapy for the treatment of patients with locally advanced, adenoid cystic carcinoma of minor salivary glands and to identify prognostic variables associated with local control, overall survival, and cause specific survival. Methods and Materials: Eighty-four patients having adenoid cystic carcinoma of minor salivary glands were treated with fast neutron radiotherapy during the years 1985-1994. All patients had either unresectable disease or gross disease remaining after attempted surgical extirpation. Seventeen patients had previously received conventional radiotherapy and their subsequent treatment fields and doses for neutron radiotherapy were modified for critical sites (brainstem, spinal cord, brain). Although the median doses (tumor maximum and tumor minimum) only varied by ≤10%, treatment portals were substantially smaller in these patients because of normal tissue complication considerations. Twelve patients (13%) had distant metastases at the time of treatment and were only treated palliatively with smaller treatment portals and lower median tumor doses (≤80% of the doses delivered to curatively treated patients). Seventy-two patients were treated with curative intent, with nine of these having recurrent tumors after prior full-dose radiotherapy. The median duration of follow-up at the time of analysis was 31.5 months (range 3-115). Sites of disease and number of patients treated per disease site were as follows: paranasal sinus--31; oral cavity--20; oropharynx--12; nasopharynx--11; trachea--6; and other sites in the head and neck--4. Results: The 5-year actuarial local-regional tumor control rate for all patients treated with curative intent was 47%. Patients without involvement of the cavernous sinus, base of skull, or nasopharynx (51 patients) had a 5-year actuarial local-regional control rate of 59%, whereas local-regional control was significantly lower (15%) for patients with tumors involving

    Full Text Available A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite cricoid invasion. Locoregional extension of disease was noted invading the thyroid and abutment of the carotid approximately 180°. Intraoperative findings identified tracheal mucosal disease extending distal to the carina and proximally at the cricothyroid joints where bilateral functional recurrent nerves were preserved. A decision made to preserve the larynx given the inability to fully resect distal tracheal disease. A 5 cm sleeve resection of the trachea was made with a cricotracheal anastomosis following suprahyoidal muscle release and laryngeal drop-down. The patient was treated with adjuvant radiotherapy including platinum based chemotherapy in an effort to maximise local control. PET scanning three months after therapy revealed no FDG uptake locally or distally.

    Full Text Available Background: High-grade transformation or dedifferentiation in carcinoma is progression of a low-grade malignant neoplasm to a high-grade carcinoma or poorly differentiated adenocarcinoma. This is rarely observed in adenoid cystic carcinoma of the salivary glands. Case Report: A 39 year-old woman presented with a painless mass at the left submandibulary region that had been growing slowly for 5 years. Submandibulary mass resection revealed a mass with peripheral adenoid cystic carcinoma and a central high-grade tumor delineated with a fibrous rim, raising the possibility of a hybrid or composite carcinoma, requiring differential diagnosis depending upon morphology and immunohistochemistry findings. The final histopathological diagnosis was high-grade transformation of adenoid cystic carcinoma. After surgical therapy, the patient was irradiated to the neck and submandibulary region. No sign of tumor recurrence has been evident for 36 months. Conclusion: This present case seems to be another rare case with high-grade transformation of adenoid cystic carcinoma and the fibrous rim may be a histopathological feature of such cases, which should be kept in mind.

    The incidence of an adenoid cystic carcinoma on major salivary glands is low, constituting only about 10% to 15% of all parotid malignancies. Cases of delayed metastasis have been reported, but reports of specific renal involvement have not been extensively found. We present the case of a 21-year-old woman with a left renal metastasis from an adenoid cystic carcinoma of the parotid gland that had been surgically treated 7 years previously. The patient underwent successful left radical nephrectomy. During follow-up, the patient developed pulmonary nodules that were metastatic adenoid cystic carcinoma and were surgically excised. At last follow-up, the patient was doing well with no evidence of disease.

    2013-01-01

    Background Malignant tumours of minor salivary glands are uncommon, representing only 2-4% of all head and neck cancers. In the larynx, minor salivary gland tumours rarely occur and constitute less than 1% of laryngeal neoplasm. Most of the minor salivary gland tumours arise in the subglottis; however, they can also occur in the supraglottis, in the false vocal cords, aryepiglottic folds and caudal portion of the epiglottis. The most common type of malignant minor salivary gland tumour is adenoid cystic carcinoma. Methods We present a unusual case of adenoid cystic carcinoma of glottic-subglottic region in a 61-year-old woman. Follow-up endoscopy and laryngeal magnetic resonance imaging (MRI) at three years after treatment showed no recurrence of the tumour. Results The diagnosis of glottic-subglottic adenoid cystic carcinoma should be considered in patients who are characterized by dyspnea, cough and stridor, but do not respond to pharmacologic approach. Conclusions Adenoid cystic carcinoma is usually a very slow growing cancer, invested by an apparently normal laryngeal mucosa, so that it can show no clear symptoms for a long time. For these reasons the increasing number of diagnostic mistakes or late diagnosis that may be fatal in some cases. PMID:24427787

    Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast adenoid cystic carcinomas. All breast and lacrimal gland adenoid cystic carcinomas had triple-negative and basal-like phenotypes, while salivary gland tumors were indeterminate in 13% of cases. Aberrations in MYB and/or NFIB were found in the majority of cases in all three locations, whereas MYBL1 involvement was restricted to tumors in the salivary gland. Global microRNA expression profiling separated salivary and lacrimal gland adenoid cystic carcinoma from their respective normal glands but could not distinguish normal breast adenoid cystic carcinoma from normal breast tissue. Hierarchical clustering separated adenoid cystic carcinomas of salivary gland origin from those of the breast and placed lacrimal gland carcinomas in between these. Functional annotation of the microRNAs differentially expressed between salivary gland and breast adenoid cystic carcinoma showed these as regulating genes involved in metabolism, signal transduction, and genes involved in other cancers. In conclusion, microRNA dysregulation is the first class of molecules separating adenoid

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    Full Text Available A 60-year-old male patient came to ENT OPD with complaints of left nasal obstruction from the last 5 years and moderate quantity of epistaxis from the last 4 months. It was associated with foul smelling mucopurulent rhinorrhea. On clinical examination, a fleshy mass was seen occupying the posterior part of left nasal cavity and displacing the septum on the right side. The mass was relatively painful, soft, and bleeding on touch. The provisional diagnosis of "vascular-tumor-like" angiofibroma was suspected. Diagnostic nasal endoscopy and CT scan PNS were done which revealed a mass occupying the left nasal cavity arising from the posterior part of septum along the choanae till the anterior part of sphenoid sinus. Biopsy of the same revealed an adenoid cystic carcinoma. Adenoid cystic carcinoma is uncommon and that too of the nasal cavity. The cases of the adenoid cystic carcinoma involving the nasal cavity usually involves the lateral wall and the involvement of the posterior part of nasal septum is extremely rare. Thus the presentation of this uncommon disease is discussed here.

    2011-05-01

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    Two cases of severe tracheal stenosis due to advanced nonresectable adenoid cystic carcinoma of the trachea were reported. Case 1 was a 38-year-old male who underwent emergency {sup 60}Co irradiation following endoscopic YAG laser irradiation. This approach was quite effective. Proton irradiation was effective against tumor recurrence. Case 2 was a 28-year-old female in whom emergency treatment for tracheal obstruction due to edema after laser therapy necessitated transient tracheal intubation. The tracheal stenosis due to recurrent tumor after {sup 60}Co irradiation was improved by insertion of an intraluminal permanent stent. (author).

    Full Text Available Adenoid Cystic Carcinoma (ACC is uncommonly found outside the major or minor salivary glands and is especially rare when located in nasal cavity. A case report of 13 year old boy who presented with mass in nasal cavity and epistaxis is presented here. Endoscopic removal of mass was done and histopathology revealed ACC. ACCs are slow growing tumours with a propensity for frequent local recurrence and early perineural and haematogenous spread. Early diagnosis requires a high index of suspicion for this rare pathology.

    Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

    To investigate the expression of ErbB-3 binding protein-1 (EBP-1), matrix metalloproteinase 9 (MMP-9) and E-cadherin (E-cad) in adenoid cystic carcinoma and their correlation. Immunohistochemistry(PV6000 method) was used to detect EBP-1, MMP-9 and E-cad expression in 66 cases of adenoid cystic carcinoma tissues and matched para-cancerous normal tissues. In this study all cases were successfully followed up. The positive expression rate of EBP-1 in adenoid cystic carcinoma tissues was 85%. EBP-1 expression was significantly correlated to pathological pattern and clinical stage (P correlation between EBP-1 and E-cad expression, and positive correlation between EBP-1 and MMP-9. EBP-1 and its correlation with MMP-9 and E-cad may be used as useful indicators for clinical assessment of tumor biological behavior and prognosis in patients with adenoid cystic carcinoma.

    Tissue acidosis is an important feature of tumor. The response of adenoid cystic carcinoma (ACC) cells to acidic solution was studied using whole-cell patch-clamp recording in the current study. An inward, amiloride-sensitive Na + current was identified in cultured ACC-2 cells while not in normal human salivary gland epithelial cells. Electrophysiological and pharmacological properties of the currents suggest that heteromeric acid-sensing ion channels (ASICs) containing 2a and 3 may be responsible for the proton-induced currents in the majority of ACC-2 cells. Consistent with it, analyses of RT-PCR and Western blotting demonstrated the presences of ASIC2a and 3 in ACC-2 cells. Furthermore, we observed the enhanced expression of ASIC2a and 3 in the sample of ACC tissues. These results indicate that the functional expression of ASICs is characteristic feature of ACC cells

    Translocation events are frequent in cancer and may create chimeric fusions or ‘regulatory rearrangements’ that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin maps reveal distinct chromosomal rearrangements that juxtapose super-enhancers to the MYB locus. Chromosome conformation capture confirms that the translocated enhancers interact with the MYB promoter. Remarkably, MYB protein binds to the translocated enhancers, creating a positive feedback loop that sustains its expression. MYB also binds enhancers that drive different regulatory programs in alternate cell lineages in ACC, cooperating with TP63 in myoepithelial cells and a Notch program in luminal epithelial cells. Bromodomain inhibitors slow tumor growth in ACC primagraft models in vivo. Thus, our study identifies super-enhancer translocations that drive MYB expression and provides insight into downstream MYB functions in the alternate ACC lineages. PMID:26829750

    Extracellular matrix metalloproteinase inducer (EMMPRIN) is a transmembrane glycoprotein that is involved in tumor invasion by stimulating matrix metalloproteinase (MMP) expression. Our previous immunohistochemical study found that the expression of EMMPRIN in salivary adenoid cystic carcinoma (SACC) was positively correlated with tumor perineural and perivascular invasion. The present study was designed to further investigate the role of EMMPRIN in the invasion of SACC. Western blot results showed that EMMPRIN was upregulated in the highly metastatic SACC cell line SACC-LM, compared to SACC-83, a SACC cell line with low metastatic ability. Blocking of EMMPRIN by its antibody significantly decreased the adhesion, secretion of MMP-2 and MMP-9, and invasion activity of SACC-LM cells in vitro (PEMMPRIN may play an important role in the invasion of SACC by stimulating the expression of MMP-2 and MMP-9 in tumor and stromal cells.

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature.

    Purpose: To analyze the recent experience of patients with adenoid cystic carcinoma treated with radiation therapy at Memorial Sloan-Kettering Cancer Center. Methods and Materials: From 1990 to 2004, a total of 59 patients with a diagnosis of primary adenoid cystic carcinoma of the head and neck received radiation therapy at our institution. The subsite distribution was oral cavity, 28% (n = 17); paranasal sinuses, 22% (n = 13); parotid, 14% (n = 8); submandibular, 14% (n = 8); oropharynx, 10% (n = 6); sublingual, 3% (n = 2); nasopharynx, 3% (n = 2); and other, 5% (n = 3). T Stage distribution was T1, 34% (n = 20); T2, 19% (n = 11); T3, 14% (n = 8); and T4, 34% (n = 20). Twenty-nine percent of patients (n = 17) were treated with intensity-modulated radiation therapy; 25% (n =15), with three-dimensional conformal therapy, and the remainder, with conventional techniques. Ninety percent (n = 53) of patients received treatment including the base of skull. Results: Median follow-up for surviving patients was 5.9 years. Five-year and 10-year rates of local control and distant metastases-free survival were 91%/81% and 81%/49%, respectively. Five-year and 10-year rates of disease-free and overall survival were 76%/40% and 87%/65%, respectively. On univariate analysis, stage T4 (p = 0.004) and gross/clinical nerve involvement (p = 0.002) were associated with decreased progression free survival, whereas stage T4 and lymph node involvement were associated with decreased overall survival (p = 0.046 and p < 0.001, respectively). Conclusions: Radiation therapy in combination with surgery produces excellent rates of local control, although distant metastases account for a high proportion of failures. Routine treatment to the base of skull reduces the significance of histologic perineural invasion, but major nerve involvement remains an adverse prognostic factor

    Full Text Available Adenoid cystic carcinoma (ACC is one of the most common salivary gland malignant tumors with a high risk of recurrence and metastasis. Current studies on cancer stem cells (CSCs have verified that CSCs are the driving force behind tumor initiation and progression, suggesting that new cancer therapies may be established by effectively targeting and killing the CSCs. The primary goal of this study is to investigate the expression patterns of ABCG2, CD133, and podoplanin in ACC of minor salivary glands by immunohistochemistry analysis. We found that ABCG2 was weakly expressed in normal looking salivary gland tissues. A significant upregulation of ABCG2 expression in ACC was observed with a similar expression pattern of Ki-67. CD133 was detected in apical membrane of epithelial cells and podoplanin was expressed positively in myoepithelial cells of both normal looking tissue and ACC. However, no significant difference was found of the expression pattern of CD133 and podoplanin between normal looking tissues and ACC. Our observations suggest that CSCs may exist in quiescent cells with ABCG2 positive staining, which are surrounded by cells with positive expression of ABCG2 and Ki-67 in ACC, and costaining with ABCG2 and Ki-67 may help predict the location of CSCs.

    Adenoid cystic carcinoma (ACC) in the larynx is an extremely rare entity. Although the 5-year disease-specific survival rates for laryngeal ACC are high, distant metastasis might occur up to more than 5 years post treatment. Therefore patients with ACC require long-term follow-up. To summarize the characteristics of laryngeal ACC by analyzing six cases in a single center. This was a retrospective analysis of six patients with laryngeal ACC who were treated in Beijing Tongren Hospital between 1998 and 2013. The mean age at diagnosis was 44 years, ranging from 15 to 61 years. Dyspnea was the most common complaint. All patients underwent combined-modality treatment with surgical resection and external beam radiation. The range of follow-up time varied from 1 to 7 years (median 5 years). Follow-up inspections indicated that none of them had local or regional recurrence. Distant metastasis occurred in 33.7% (2/6) of the patients, with one lung metastasis 5 years after operation and one liver metastasis 4 years after operation.

    Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

    Vorinostat is a histone deacetylase inhibitor (HDACi). Based on a confirmed partial response (PR) in an adenoid cystic carcinoma (ACC) patient treated with vorinostat in a prior phase 1 trial, we initiated this phase 2 trial. Vorinostat was administered orally 400 mg daily, 28 day cycles. The primary objective was to evaluate response rate (RR). Exploratory studies included whole exome sequencing (WES) of selected patients. Thirty patients were enrolled. Median age of patients was 53 years (range 21-73). Median number of cycles was 5 (range 1-66). Lymphopenia (n = 5), hypertension (n = 3), oral pain (n = 2), thromboembolic events (n = 2) and fatigue (n = 2) were the only grade 3 adverse events (AEs) that occurred in more than 1 patient. Eleven patients were dose reduced secondary to drug-related AEs. Two patients had a partial response (PR), with response durations of 53 and 7.2 months. One patient had a minor response with a decrease in ascites (for 19 cycles). Stable disease was the best response in 27 patients. Targeted and WES of 8 patients in this trial identified mutations in chromatin remodeling genes highlighting the role of the epigenome in ACC. Vorinostat demonstrated efficacy in patients with ACC supporting the inclusion of HDACi in future studies to treat ACC.

    Purpose: To examine the efficacy of fast neutron radiotherapy for the treatment of locally advanced and/or recurrent adenoid cystic carcinoma of the head and neck and to identify prognostic variables associated with local-regional control and survival. Methods and Materials: One hundred fifty-nine patients with nonmetastatic, previously unirradiated, locally advanced, and/or recurrent adenoid cystic carcinoma (ACC) of the head and neck region were treated with fast neutron radiotherapy during the years 1985-1997. One hundred fifty-one patients had either unresectable disease, or gross residual disease (GRD) after an attempted surgical extirpation. Eight patients had microscopic residual disease and were analyzed separately. Sixty-two percent of patients had tumors arising in minor salivary glands, 29% in major salivary glands, and 9% in other sites such as the lacrimal glands, tracheal-bronchial tree, etc. Fifty-five percent of patients were treated for postsurgical recurrent disease and 13% of patients had lymph node involvement at the time of treatment. The median duration of follow-up was 32 months (range 3-142 months). Actuarial curves for survival, cause-specific survival, local-regional control, and the development of distant metastases are presented for times out to 11 years. Results: The 5-year actuarial local-regional tumor control rate for the 151 patients with GRD was 57%; the 5-year actuarial overall survival rate was 72%; and the 5-year actuarial cause-specific survival rate was 77%. Variables associated with decreased local-regional control in the patients with GRD as determined by multivariate analysis included base of skull involvement (p < 0.01) and biopsy only versus an attempted surgical resection prior to treatment (p = 0.03). Patients without these negative factors had an actuarial local-regional control rate of 80% at 5 years. Patients with microscopic residual disease (n = 8) had a 5-year actuarial local-regional control rate of 100%. Base of

    Objective: To describe the cytologic features of adenoid cystic carcinoma (ADCC) of salivary glands, and to identify distinguishing cytologic features of ADCC and basal cell adenoma (BCA). Methods: A retrospective review of cytology smears of 30 cases of ADCC and 12 cases of BCA of salivary glands were performed. All cases were collected from Beijing Tongren Hospital, Capital Medical University from January 2010 to January 2017. Except for 2 aspirate smears of ADCC, all were touch imprint smears. All cases had further histological confirmation. Results: Neoplastic ductal cells of ADCC were arranged in three-dimensional clusters, sheets and singles. Hyaline globules were found in most cases (20/30, 66.7%). The nuclei were round to oval, showing varying degrees of nuclear atypia. These included (1) the nuclei were hyperchromatic, demonstrating coarse or slightly coarse, irregularly distributed chromatin; (2) the nuclei were slightly large and vary in size; (3) appearance of the nuclei had a different degree of irregularity (often mild). Nucleoli were common seen (21/30, 70.0%), and were prominent in some cases. Mitosis and necrosis were rare. Cytologically, BCA showed cell arrangements and nuclear features overlapped with those of ADCC. The cytologic difference between these two tumors included: (1) the tumor cells presented rarely in singles; (2) hyaline globules were very uncommon (1/12) in BCA; (3) nuclei of BCA were hypochromatic or slightly hyperchromatic, homogeneous and uniform in appearance and size, overall without nuclear atypia and they were smaller and slender then those of ADCC and (4) individual cells of BCA showed relatively abundant cytoplasm. Conclusions: The cytologic features of ADCC and BCA both overlap and different from each other. Most cases can be diagnosed by cytologic examination. The presence of hyaline globules is an important diagnostic clue of ADCC, although not pathognomonic. Nuclear atypia of neoplastic ductal cells is an essential

    Salivary adenoid cystic carcinoma (SACC) is the most frequent salivary gland malignancy with a unique characteristic that has been named perineural invasion (PNI). EMMPRIN is a transmembrane glycoprotein that has been demonstrated to promote PNI in SACC. Slug, one of the most effective promoters of the epithelial-to-mesenchymal transition (EMT), has been found to be associated with PNI in SACC. The aim of the present study was to investigate the roles and relationships of Slug, EMMPRIN, and E-cadherin in the PNI process of SACC. The expression levels of Slug, EMMPRIN, and E-cadherin in 115 primary SACC cases were statistically analyzed by immunohistochemistry. Simultaneously, the SACC cell line SACC-83 was transfected with recombinant plasmids of silencing Slug (si-Slug) and/or silencing EMMPRIN (si-EMMPRIN). The functions of Slug and EMMPRIN in the EMT and PNI process were assessed by reverse transcription PCR (RT-PCR), western blotting, morphological observation, scratch test, migration assay, and in vitro perineural invasion assay. The immunohistochemical statistics revealed that the high expression of Slug and EMMPRIN and the low expression of E-cadherin were significantly associated with the PNI of SACC (P EMMPRIN expression (P EMMPRIN expression were both significantly negatively associated with E-cadherin expression (P EMMPRIN silencing both significantly inhibited EMMPRIN expression but promoted E-cadherin expression in SACC-83 cells (P EMMPRIN, or both induced cell morphology changes and inhibited tumor cell motility and PNI ability in SACC-83 cells (P EMMPRIN and then upregulating E-cadherin in the PNI process of SACC. The present study indicated that Slug and EMMPRIN are potential biomarkers and therapeutic targets for the diagnosis and treatment of PNI in human SACC.

    Provirus integration site for Moloney murine leukemia virus 1 (Pim-1) has proved to be an oncogene and it is known that to depress Pim-1 activity may be a novel oncological treatment strategy. SGI-1776, a small molecule, is the first clinically tested inhibitor of the Pim kinase family. Here, we aimed to explore the effect of SGI-1776 on salivary adenoid cystic carcinoma (SACC). Expression of Pim-1 was confirmed in SACC and control tissues by qRT-PCR. After SGI-1776 treatment, the Pim-1 expressions and Pim-1 kinase activity in both SACC-83 and SACC-LM cell lines were measured. Cell proliferation, cell invasion, cell cycle, apoptosis and mitochondrial membrane potential were analyzed. Also, the expression of FOXO3a, p-FOXO3a, RUNX3, Bcl-2, BAD, p-BAD, Bim and p-Bim were detected by Western blot. The results showed that Pim-1 was significantly overexpressed in SACC tissues. SGI-1776 down-regulated the Pim-1 expression, inhibited Pim-1 kinase activity, reduced cell proliferation, decreased invasive ability, increased caspase-3 activity and induced apoptosis, cell cycle arrest and mitochondrial depolarization. Reduced expression was also seen in p-FOXO3a, RUNX3, Bcl-2, p-BAD and p-Bim, whereas no significant changes were observed from FOXO3a, BAD and Bim. These results confirm the pivotal role of Pim-1 in SACC and suggest that targeting Pim-1 kinase signal pathway by SGI-1776 might be a promising therapeutic modality for SACC.

    Full Text Available BackgroundPulmonary mucoepidermoid carcinoma (PMEC and pulmonary adenoid cystic carcinoma (PACC are the two major types of primary salivary gland-type (PSGT lung cancers. The demographic profile, clinicopathological features, and predictors of survival as an overall group have not been described for PSGT cancers of lung.MethodsIn this study, we analyzed demographic, clinical, and survival data from 1,032 patients (546 PMEC and 486 PACC who were diagnosed of PSGT lung cancer in the Surveillance, Epidemiology and End Results database from 1973 to 2014.ResultsThe PSGT constituted 0.09% of all lung cancers with age-adjusted incidence rate of 0.07 per 100,000 person-years and change of −32% from 1973 to 2014. The incidence of PMEC was slightly higher than PACC but there were no differences in the age and sex distribution. PACCs (55% were significantly higher at trachea and main bronchus while PMECs were more common at peripheral lungs (85%. Most of the tumors were diagnosed at an early stage and were low grade irrespective of histology. As compared to PMEC, significantly higher number of patients with PACC underwent radical surgery and received adjuvant radiation. The 1- and 5-year cause-specific survival was 76.6 and 62.8%, respectively. On multivariate analysis, the survival was affected by age at diagnosis, tumor stage, histological grade, period of diagnosis, and surgical resection. The histology showed strong interaction with time and hazard ratio of patients with PACC was significantly worse than patients with PMEC only after 5 years.ConclusionThe incidence of pulmonary PSGT cancer is 7 cases per 10 million population in the United States and is decreasing. There was no difference between demographic profile of patients with PMEC and PACC but pathological features were diverse. The difference in the survival of patients with the two histological types surfaced only after 5 years when survival of patients with PMEC was better than PACC.

    2017-08-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare form of adenocarcinoma, which is a broad term describing any cancer that begins in the glandular tissues. It can be found in the head and neck. We report a patient with recurrent ACC arising from the submandibular gland, treated with 100 mg/m2 nedaplatin every 4 weeks. Although our patient’s lactate dehydrogenase levels, which is produced by ACC, showed a rising trend throughout the treatment, the level decreased for approximately 2 weeks immediately after administration of nedaplatin every 4 weeks. Thus, there is a possibility that the agent may be effective. Complications such as anorexia and nausea were observed, but they were tolerated and manageable. Nedaplatin may be considered as a supportive agent during palliative therapy for patients with ACC. More clinical trials regarding nedaplatin are necessary, as this study may indicate that a medical approach works well for ACC.

    Adenoid cystic carcinoma of the salivary glands has a propensity for perineural invasion, which could favor spread along the major cranial nerves, sometimes to the skull base and through the foramina to the brain parenchyma. This study evaluated the relationship between neural spread and relapse in the skull base. During surgery, we performed multiple biopsies with extemporaneous examination of the major nerves close to the tumor to guide the surgical resection. The percentage of actuarial local control at 5 years for patients with a positive named nerve and skull base infiltration was 12.5%, compared with 90.0% in patients who were named nerve-negative and without infiltration of the skull base (P = .001). Our study shows that local control of disease for patients who are named nerve-positive with skull base infiltration is significantly more complex compared with patients who are named nerve-negative without infiltration of the skull base.

    Adenoid Cystic Carcinoma (ACC) is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread. We report the first case of the 5 th and 6 th nerve palsy due to cavernous sinus invasion by adenoid cystic carcinoma. A 49-year-old African American female presented to the emergency room complaining of severe right-sided headache, photophobia, dizziness and nausea, with diplopia. The patient had a 14 year history migraine headaches, hypertension, and mild intermittent asthma. Physical examination revealed right lateral rectus muscle palsy with esotropia. There was numbness in all three divisions of the right trigeminal nerve. Motor and sensory examination of extremities was normal. An MRI of the brain/brain stem was obtained which showed a large mass in the clivus extending to involve the nasopharynx, pterygoid plate, sphenoid and right cavernous sinuses. Biopsy showed an ACC tumor with a cribriform pattern of the minor salivary glands. The patient underwent total gross surgical resection and radiation therapy. This is a case of ACC of the minor salivary glands with intracranial invasion. The patient had long history of headaches which changed in character during the past year, and symptoms of acute 5 th and 6 th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5 th and 6 th cranial nerve involvement as histopathology revealed no perineural invasion

    Purpose: This study sought to review a single-institution experience with the management of adenoid cystic carcinoma of the head and neck. Methods and Materials: Between 1960 and 2004, 140 patients with adenoid cystic carcinoma of the head and neck were treated with definitive surgery. Ninety patients (64%) received postoperative radiation to a median dose of 64 Gy (range, 54-71 Gy). Distribution of T stage was: 26% T1, 28% T2, 20% T3, and 26% T4. Seventy-eight patients (56%) had microscopically positive margins. Median follow-up was 66 months (range, 7-267 months). Results: The 5- and 10-year rate estimates of local control were 88% and 77%, respectively. A Cox proportional hazards model identified T4 disease (p = 0.0001), perineural invasion (p = 0.008), omission of postoperative radiation (p = 0.007), and major nerve involvement (p = 0.02) as independent predictors of local recurrence. Radiation dose lower than 60 Gy (p = 0.0004), T4 disease (p 0.005), and major nerve involvement (p = 0.02) were predictors of local recurrence among those treated with surgery and postoperative radiation. The 10-year overall survival and distant metastasis-free survival were 64% and 66%, respectively. Conclusion: Combined-modality therapy with surgery followed by radiation to doses in excess of 60 Gy should be considered the standard of care for adenoid cystic carcinoma of the head and neck

    1996-12-01

    Concerning the hypothesis that distinct types of salivary gland cysts may be the starting point of a salivary gland tumour, a histological examination of 1,661 salivary gland cysts was performed in order to analyse the cell types and their proliferative activity. Epithelial alterations were found especially in salivary duct cysts of parotid gland and in mucous retention cysts of minor salivary glands. Characteristic cellular changes were epithelial metaplasias (goblet cells, clear cells, squamous cells) and focal epithelial proliferations with plump or papillary plaques projecting into the cyst lumen. Only in one case had a mucoepidermoid carcinoma developed in the wall of a parotid duct cyst. The epithelial metaplasia and focal proliferative activity in salivary duct cysts is comparable to similar alterations in odontogenic cysts as possible early manifestation of a tumour, especially of an ameloblastoma or mucoepidermoid carcinoma. The differential diagnosis of salivary duct cysts must take primarily cystadenomas and cystic mucoepidermoid carcinomas of well-differentiated type into account.

    2017-05-01

    Full Text Available Adenoid cystic carcinoma (ACC is an uncommon malignancy of the salivary glands that is characterized by local recurrence and distant metastasis due to its resistance to conventional therapy. Platinum-based therapies have been extensively explored as a treatment for ACC, but they show little effectiveness. Studies have shown that a specific group of tumor cells, harboring characteristics of cancer stem cells (CSCs, are involved in chemoresistance of myeloid leukemias, breast, colorectal and pancreatic carcinomas. Therapeutic strategies that target CSCs improve the survival of patients by decreasing the rates of tumor relapse, and epigenetic drugs, such as histone deacetylase inhibitors (HDACi, have shown promising results in targeting CSCs. In this study, we investigated the effect of the HDACi Suberoylanilide hydroxamic acid (Vorinostat, and cisplatin, alone or in combination, on CSCs and non-CSCs from ACC. We used CSCs as a biological marker for tumor resistance to therapy in patient-derived xenograft (PDX samples and ACC primary cells. We found that cisplatin reduced tumor viability, but enriched the population of CSCs. Systemic administration of Vorinostat reduced the number of detectable CSCs in vivo and in vitro, and a low dose of Vorinostat decreased tumor cell viability. However, the combination of Vorinostat and cisplatin was extremely effective in depleting CSCs and reducing tumor viability in all ACC primary cells by activating cellular senescence. These observations suggest that HDACi and intercalating agents act more efficiently in combination to destroy tumor cells and their stem cells.

    Retrorectal, developmental tail gut cysts, include dermoid cysts, rectal duplication cysts and retrorectal cyst-hamartomas. Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hind gut, which normally involutes by the 8th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and teratomas). We report a patient with adenosquamous carcinoma arising within RCH, who underwent complete resection of the cyst through anterior laparotomy, and reached complete (recurrencefree for 14 mo, so far) functional recovery. The cyst was incidentally discovered during hysterectomy 12 years ago.Diagnostic, therapeutic and histopathological aspects of this rare case are discussed. The mentioned period between diagnosis and surgical treatment suggests that RCH, given enough time, can develop malignant degeneration, and should be resected at the time of diagnosis.

Materials and methods: This article screened the abstract and full-text papers that investigated salivary gland primary ACC of head and neck. Two independent reviewers searched for articles published before October 2017 in three databases (Web of Science, PubMed, and Ovid, having no limits in date and language. Statistical data were analyzed statistically by Review Manager 5.3. Results: In total, 18 studies involving 2993 patients were included in the analysis. Of the 2993 patients, 473 patients had cervical lymph node metastasis, with a merge frequency of 16% (95% CI: 13–19. Among included articles, only 4 involved cervical lymph node occult metastases, with a merge frequency of 14% (95% CI: 9–20. There were 5 articles containing minor salivary glands (MiSGs involving 370 patients of which 92 patients had cervical lymph node metastases and the merge frequency was 25% (95% CI: 11–38. Moreover, there were 4 studies on major salivary glands involving 904 patients of which 158 patients had cervical lymph node metastases and the merge frequency was 17% (95% CI: 15–20. Conclusion: Elective neck dissection is unnecessary for all patients with salivary gland ACC of head and neck. Moreover, compared with major salivary glands, MiSGs have a higher cervical lymph node metastases rate in ACC. The overall cervical lymph node metastases rate of MiSGs is 25%, which is enough to attract our attention. Therefore, we suggest that neck dissection might be

    Adenoid cystic carcinoma (ACC) of the breast is a rare type of breast cancer, which presents inconsistencies in the optimal management strategy. A retrospective review of prospectively collected data, spanning the last 20 years, was performed using the cancer registry database at our institution. Six patients were diagnosed with ACC of the breast, out of 5,813 total patients diagnosed with breast cancer (0.1%). Our identified patients had a median age of 66, all with the early stage cancer (Stage I/II). The average size of the breast lesion was 1.62 cm, and nodal status was negative for all cases. All patients had resection as primary therapy (partial or total mastectomy), with one patient also undergoing external beam radiation and tamoxifen hormonal therapy. Median follow-up was 85 months, with all patients being disease-free at last follow-up. ACC of the breast has an indolent course, despite triple negative status. Our study suggests that radiation may not be warranted and confirms the rarity of axillary node metastases, indicating that sentinel node excision may also not be necessary. Ultimately, the hope is that our findings along with the reviewed literature will aid in determining the most appropriate options for management of ACC of the breast.

  4. RadioImmunotherapy for adenoid cystic carcinoma: a single-institution series of combined treatment with cetuximab

    2010-01-01

    Background Local control in adjuvant/definitive RT of adenoid cystic carcinoma (ACC) is largely dose-dependent. However, some clinical situations do not allow application of tumouricidal doses (i.e. re-irradiation) hence radiation sensitization by exploitation of high endothelial growth factor receptor (EGFR)-expression in ACC seems beneficial. This is a single-institution experience of combined radioimmunotherapy (RIT) with the EGFR-inhibitor cetuximab. Methods Between 2006 and 2010, 9 pts received RIT for advanced/recurrent ACC, 5/9 pts as re-irradiation. Baseline characteristics as well as treatment parameters were retrieved to evaluate efficacy and toxicity of the combination regimen were evaluated. Control rates (local/distant) and overall survival were calculated using Kaplan-Meier estimation. Results Median dose was 65 Gy, pts received a median of 6 cycles cetuximab. RIT was tolerated well with only one °III mucositis/dysphagia. Overall response/remission rates were high (77,8%); 2-year estimate of local control was 80% hence reaching local control levels comparable to high-dose RT. Progression-free survival (PFS) at 2 years and median overall survival were only 62,5% and 22,2 mo respectively. Conclusion While local control and treatment response in RIT seems promising, PFS and overall survival are still hampered by distant failure. The potential benefit of RIT with cetuximab warrants exploration in a prospective controlled clinical trial. PMID:21047402

    Adenoid cystic carcinoma (ACC) is the most common malignant epithelial cancer of the lacrimal gland. Despite a slow rate of growth, ACCs are ultimately associated with poor clinical outcome. Given the rarity of this disease, most recommendations regarding therapy are guided by expert opinion and retrospective data rather than level 1 evidence. Surgery and postoperative radiation therapy are commonly used as initial local treatment. In patients at high risk of recurrence, concomitant platinum-based chemotherapy may be added to postoperative radiotherapy in an attempt to enhance radio-sensitivity. While encouraging responses have been reported with intra-arterial neoadjuvant chemotherapy, this strategy is associated with substantial toxicity and should be considered investigational. For patients with metastatic disease not amenable to surgery or radiotherapy, chemotherapy may have a role based on its modest efficacy in non-lacrimal ACC. Similarly, molecular targeted agents may have a role, although the agents tested to date in non-lacrimal ACC have been disappointing. A better understanding of the biology of ACC will be crucial to the future success of developing targeted agents for this disease.

    Full Text Available Abstract Objectives This study consisted of two parts. One part was to analyze the survival rates of adenoid cystic carcinoma (ACC in Chinese and explain the difference between our data and the literature. The other was to analyze the relationship between the expression of CD117 and the histological grade and the prognosis. Methods A retrospective study of 80 ACC patients was performed. Clinical data were collected, and p63, CD117 were detected by immunohistochemical staining. Results Eighty patients received follow-ups 3 to 216 months after initial diagnosis. ACC occurred in the lacrimal gland (26.3%, n = 21, nasal cavity and parasinus (33.8%, n = 27 and other sites (40.0%, n = 33. The 5-year and 10-year survival rates were 66.41% and 10.16%, respectively. Over expression of CD117 was detected in p63-negative cells in 94.3% of cases and in p63-positive cells in 45.8%. The expression of CD117 in p63-positive cells was significantly associated with the histological grade (P Conclusions ACC had a good 5-year survival but poor 10-year survival in Chinese, which differed from the occidental data. More p63+/CD117+ cells were associated with a higher histological grade and poorer outcome.

    Thymidylate synthase (TS) is an important target for chemotherapeutic treatment of cancer and high expression of TS has been associated with poor prognosis or refractory disease in several cancers including colorectal and head and neck cancer. Although TS is known to regulate cell cycles and transcription factors, its potency as a therapeutic target has not been fully explored in adenoid cystic carcinoma (ACC). An ACC cell line (ACC3) was transfected with siRNA targeting the TS gene and inhibition of cell growth and induction of apoptosis-associated molecules were evaluated in vitro. In addition, the in vivo effect of TS siRNA on tumor progression was assessed using a xenograft model. Our results demonstrated that ACC3 cells showed significantly higher TS expression than non-cancer cell lines and the induction of TS siRNA led to inhibition of cell proliferation. The effect was associated with an increase in p53, p21, and active caspase-3 and S-phase accumulation. We also found up-regulation of spermidine/spermine N1-acetyltransferase (SSAT), a polyamine metabolic enzyme. Furthermore, treatment with TS siRNA delivered by atelocollagen showed a significant cytostatic effect through the induction of apoptosis in a xenograft model. TS may be an important therapeutic target and siRNA targeting TS may be of potential therapeutic value in ACC

    Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In the present study, we investigated the effects of a DNA methyltransferase (DNMT) inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the RECK gene and tumor invasion in SACC cell lines. Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR were used to investigate the methylation status of the RECK gene and expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment

    Adenoid cystic carcinoma (AdCC) of the head and neck is an uncommon malignant epithelial tumour of the secretory glands. Many patients develop slowly growing local recurrence and/or distant metastasis, for which treatment options are limited. A retrospective analysis of 9 AdCC patients was conducted to analyse the visualization of AdCC on PSMA PET/CT and to investigate the expression of PSMA on primary, recurrent and metastatic AdCC tumour tissue using immunohistochemistry. Local recurrence occurred in six patients and eight developed distant metastasis. All PET/CTs depicted PSMA-ligand uptake. Four PSMA PET/CTs showed suspected residual disease, eight scans depicted uptake in areas suspected of distant metastasis. Median Maximum Standardized Uptake Value (SUV{sub max}) in local recurrent and distant metastatic AdCC was 2.52 (IQR 2.41-5.95) and 4.01 (IQR 2.66-8.71), respectively. All primary tumours showed PSMA expression on immunohistochemistry (5-90% expression), as well as all available specimens of local recurrence and distant metastases. PSMA PET/CT is able to detect and visualize local recurrent and distant metastatic AdCC. PSMA-specific targeting is supported by PSMA expression on immunohistochemistry. (orig.)

    Full Text Available Abstract Introduction Treatment for squamous cell carcinoma of the head and neck has significantly improved with the addition of cetuximab, a monoclonal antibody against the epidermal growth factor receptor, to conventional cytotoxic agents. The most significant aspect of this treatment approach is the proof that head and neck cancers are suitable for targeted therapies as has been shown in other malignancies. Unfortunately, there are other rare histologic types of head and neck cancer such as adenocarcinoma and adenoid cystic carcinoma. The latter has traditionally been considered to be chemotherapy resistant and surgical resection with or without adjuvant radiation therapy has been the rule as far as treatment is concerned. The course of adenoid cystic carcinoma ranges from indolent to aggressive; however, most patients succumb to the disease as a result of distant metastases. This clinical scenario poses a challenge to oncologists. Several conventional chemotherapy regimens and novel targeted agents have been tried in this rare histologic subtype without success. Case presentation In this case report, we present a 59-year-old Caucasian female with refractory adenoid cystic carcinoma of the maxilla metastatic to the lung that responded to sorafenib, a novel multi-tyrosine kinase inhibitor, which targets angiogenesis, Raf kinase pathway, platelet-derived growth factor Ret, and c-Kit. Conclusion This case illustrates the possibility that this chemoresistant tumor may need the inhibition or blocking of several oncogenic pathways. Certainly, it is imperative that more studies are done in this special population trying to identify tumorigenesis mechanisms that may be upregulated in this malignancy and could be potential targets for therapeutic development.

    Full Text Available Background : Mexico′s National Institute of Respiratory Diseases (NIRD is a third-level national reference center. Primary adenoid cystic carcinoma (PACC is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed. Materials and Methods: This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009. Results: We identified 9 cases of PACC (67% female out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57, and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO 2 and 28.5 mmHg for pCO 2 . Median FVC was 78%, while FEV 1 was 77% with an FEV 1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26 after the initial diagnosis. Conclusions: The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%. According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.

  15. Epithelial mesenchymal transition is required for acquisition of anoikis resistance and metastatic potential in adenoid cystic carcinoma.

    Directory of Open Access Journals (Sweden)

    Jun Jia

    Full Text Available Human adenoid cystic carcinoma (ACC is characterized by diffused invasion of the tumor into adjacent organs and early distant metastasis. Anoikis resistance and epithelial mesenchymal transition (EMT are considered prerequisites for cancer cells to metastasize. Exploring the relationship between these processes and their underlying mechanism of action is a promising way to better understand ACC tumors. We initially established anoikis-resistant sublines of ACC cells; the variant cells revealed a mesenchymal phenotype through Slug-mediated EMT-like transformation and displayed enhanced metastatic potential both in vitro and in vivo. Suppression of EMT by knockdown of Slug significantly impaired anoikis resistance, migration, and invasion of the variant cells. With overexpression of Slug and Twist, we determined that induction of EMT in normal ACC cells could prevent anoikis, albeit partially. These findings strongly suggest that EMT is indispensable in anoikis resistance, at least in ACC cells. Furthermore, we found that the EGFR/PI3K/Akt pathway acts as the common regulator for EMT-like transformation and anoikis resistance, as confirmed by their specific inhibitors. Gefitinib and LY294003 restored the sensibilities of anoikis-resistant cells to anoikis and simultaneously impaired their metastatic potential. In addition, the results from our in vivo model of metastasis suggest that pretreatment with gefitinib promotes mouse survival by alleviating pulmonary metastasis. Most importantly, immunohistochemistry of human ACC specimens showed a correlation between the overexpression of Slug and EGFR staining. This study has demonstrated that Slug-mediated EMT-like transformation is required by human ACC cells to achieve anoikis resistance and their metastatic potential. Targeting the EGFR/PI3K/Akt pathway holds potential as a preventive strategy against distant metastasis of ACC.

    Forty eight patients with adenoid cystic carcinoma(ACC) in the head and beck treated between 1979 and 1990 were reviewed according to treatment modalities and clinical courses. The common site of origin was minor salivary gland (69%), mostly had palate and maxillary sinus. 11 patients received radiation therapy(RT) alone and 37 patients received combined surgery and radiation therapy. The follow-up period of the survivors ranged from 4 to 118 months (median 49.5 months). The 5 year local control rate was 69.3%, 67.3% and 83.9% in RT alone, conservative operation(OP)+RT and radical OP+RT group, respectively(p>0.05). The control of local disease was best achieved with radical OP+RT. In postoperative RT, high dose (≥60 Gy) and generous field size (>64cm 2 ) yielded a better local control rate. Actuarial overall survival rate was 79.0%, at 5 years and 19.2% at 10 years. Distant metastases (DM) developed in 40% of patients, mostly in the lung. Disease-free(NED) survival rate was 45.8%, at 5 years and significant differences did not exist according to primary sites and treatment options. Survival rate after the onset of DM was 19.5% at 5 years. Occurrence of DM tends to lower survival significantly. In an effort to find the role of RT in the treatment of ACC, our data suggest that a well-planned postoperative RT employing a high dose and generous field size can produce high local control rate and remaining urgent problem of distant metastasis demands more effective chemotherapy for the purpose of improving survival of ACC patients

    The type II alveolar epithelial cell is one of two pluripotential stem cell phenotypes in normal mammalian lung morphogenesis; cells manifesting this phenotype have been found to constitute bronchioloalveolar regions of canine adenocarcinomas. We now studied type II cell expression in canine acinar adenocarcinomas and adenoid cystic (bronchial gland) carcinomas, using the same bronchogenic carcinoma model (subcutaneous bronchial autografts treated with 3-methylcholanthrene). Distinctive features of type II cells are the approximately cuboid cell shape, large and roundish nucleus, immunofluorescent staining of the cytoplasm for the surfactant protein SP-A, and presence of multilamellar bodies or their precursory forms. Cells with these type II cell characteristics were found in the basal epithelial layer of all tumor lesions and in upper layers as far as the lumen, singly or in clusters; they were also found in early invasive carcinomatous lesions but not in bronchial glands or bronchial epithelium before carcinogen exposure. Immunoblots of tumor homogenates showed reactive proteins within size classes of SP-A (28 to 36 kd) or its dimeric form (56 to 72 kd). These findings and those previously reported are consistent with the concept that chemical carcinogenesis in the adult bronchial epithelium may lead to type II cell carcinomas of varying glandular (acinar, adenoidcystic or bronchioloalveolar) growth patterns.

    Full Text Available The thyroglossal duct cysts (TGDCs are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.

The ACCEPT trial is a prospective, mono-centric, phase I/II trial evaluating toxicity (primary endpoint: acute and late effects) and efficacy (secondary endpoint: local control, distant control, disease-free survival, overall survival) of the combined treatment with IMRT/carbon ion boost and weekly cetuximab in 49 patients with histologically proven (≥R1-resected, inoperable or Pn+) ACC. Patients receive 18 GyE carbon ions (6 fractions) and 54 Gy IMRT (2.0 Gy/fraction) in combination with weekly cetuximab throughout radiotherapy. The primary objective of ACCEPT is to evaluate toxicity and feasibility of cetuximab and particle therapy in adenoid cystic carcinoma.

    To investigate the inhibitory effect and underlying mechanism of total saponins from Paris polyphylla var. yunnanensis on the proliferation of salivary adenoid cystic carcinoma ACC-83 cells. In vitro cell culture was performed. The proliferation of ACC-83 cells treated with different concentrations (5, 10, 20, 40, 60, 80, 100 μg·mL⁻¹) of total saponins from Paris polyphylla var. yunnanensis was observed using CCK-8 assay. Meanwhile, the apoptosis of ACC-83 cells treated with different concentrations (25, 50, 100 μg·mL⁻¹) of the total saponins was observed using flow cytometry. The expression levels of macrophage migration inhibitory factor (MIF) and CD74 were measured using Western blot and reverse transcription-polymerase chain reaction. The total saponins from Paris polyphylla var. yunnanensis induced apoptosis and expressed dose-effect relationship. ACC-83 cells expressed MIF and CD74, and the total saponins suppressed MIF and CD74 expression in ACC-83 cells. The total saponins from Paris polyphylla var. yunnanensis can significantly inhibit the proliferation, suppress MIF and CD74 expression, and promote apoptosis in ACC-83 cells. This study provides a theoretical basis for the treatment of salivary adenoid cystic carcinoma using Paris polyphylla var. yunnanensis.

    Full Text Available Objective To report the diagnosis and treatment of one case of adenoid glioblastoma and investigate the clinicopathological features, diagnosis and differential diagnosis. Methods and Results A 63-year-old male patient suffered from left-skewed corner of the mouth for more than 10 d. Brain enhanced MRI revealed a cystic mass in left frontotemporal lobe and metastatic tumor was considered. 18F-fluoro-2-deoxy-D-glucose (18F-FDG PET did not detected any sign of malignant neoplasm in the whole body. Under the guide of neuronavigation and ultrasound, the tumor was totally removed under microscope. Histologically, the tumor was located in brain parenchyma and presented a growing pattern of multicentric sheets or nests. Mucus scattered in some regions. Tumor cells were arranged in strip, cribriform, adenoid or papillary patterns. Tumor cells contained few cytoplasm with round or oval uniform hyperchromatic nuclei and occasionally obvious nucleoli. Proliferation of glomeruloid vascular endothelial cells could be seen. Immunohistochemical staining showed the cytoplasm of tumor cells was diffusively positive for glial fibrillary acidic protein (GFAP, vimentin (Vim and phosphatase and tensin homologue (PTEN; nuclei was positive for oligodendrocytes transcription factor-2 (Olig-2 and P53; cytoplasm and nuclei were positive for S-100 protein (S-100; membrane was positive for epidermal growth factor receptor (EGFR. The tumor cells showed a negative reaction for cytokeratin (CK, epithelial membrane antigen (EMA, carcinoembryonic antigen (CEA, thyroid transcription factor-1 (TTF-1, CD31, CD34, CAM5.2 and isocitrate dehydrogenase 1 (IDH1. Ki-67 labeling index was 76.80%. The final pathological diagnosis was adenoid glioblastoma. The patient died of respiratroy failure and circulation function failure 12 d after operation. Conclusions Adenoid glioblastoma was a rare glioblastoma subtype. A clear diagnosis depends on histological findings and immunohistochemical

Fluorescence microscopy and transmission electron microscopy were used to observe the autophagic process. Western blot was performed to detect the expression of microtube-related protein 1 light-chain 3 (LC3. An experimental adenoid cystic carcinoma (ACC lung metastasis model was established in nude mice to detect the impacts of SIL on lung weight and lung cancer nodules. Immunohistochemistry was used to detect the expressions of LC3 in human ACC samples and normal salivary gland tissue samples.Results: SIL inhibited the proliferation of ACC-M cells in a dose- and time-dependent manner, and inductively increased the autophagic bodies in ACC-M cells. Furthermore, SIL could increase the expression of LC3 in ACC-M cells and promote the conversion of LC3-I into LC3-II in a dose- and time-dependent manner. In the ACC lung metastasis model, the lung weight and left and right lung nodules in the SIL-treated group were significantly less than those in the control group (P<0.05. The expressions of LC3-I and LC3-II as well as the positive expression rate of LC3 (80% significantly increased, but the positive expression of LC3 in human ACC (42.22% reduced significantly.Conclusion: SIL could inhibit the proliferation and lung metastasis of ACC-M cells by possibly inducing tumor cells autophagy.

    The occurrence and diagnosis of thyroglossal duct carcinoma is very rare. The synchronous occurrence of papillary carcinomas arising in a thyroglossal duct cyst (TGDC) and thyroid gland is extremely rare. Sistrunk's surgical technique must always be the initial treatment for a TGDC. However, if there is an intra-thyroidal carcinoma or local invasion, thyroidectomy has to be considered. Accurate pre-operative radiological evaluation should be performed in order to plan a surgical strategy. The aim of this report was to review our experience in the management of papillary thyroid carcinoma associated with TGDC. Our patient was a 67-year-old man who had a mural, micro- calcified nodule within a palpable, thick-walled cyst at the level of the hyoid and synchronously, a small macro-calcified mass in the isthmus of the thyroid gland.

    We herein present a case of a left cervical cystic mass, for which the initial pathological diagnosis was branchial cleft cyst carcinoma (following complete mass excision). Thorough postoperative examinations, including with FDG positron emission tomography/computed tomography (PET/CT), revealed a primary tumor in the retromolar region of the left mandible. A 52-year-old female presented with a 2-month history of a painless, progressively enlarged left-sided neck mass. Fine-needle aspiration biopsy suggested a branchial cleft cyst. Physical examination revealed a 3 × 3-cm smooth, tender mass in the upper-left neck and anterior border of the sternocleidomastoid muscle. Examination using nasendoscopy and a strobolaryngoscope revealed no abnormalities of the nasal cavity, nasopharynx, oropharynx, hypopharynx or larynx. MRI of the neck revealed a solitary, round, cystic mass under the left parotid gland. The mass was excised completely. Pathologic results indicated a branchial cleft cyst carcinoma. According to the diagnostic criteria for a branchial cleft cystic carcinoma, PET/CT was performed to detect the occult primary site. PET/CT revealed high FDG uptake in the tooth root of the left mandible. Frozen sections of the mass were indicative of moderate, differentiated squamous cell carcinoma. The carcinoma in the retromolar region of the left mandible was locally excised under general anesthesia. A partial left maxillectomy, partial mandibulectomy, and left radical neck dissection were performed. The patient received postoperative concurrent chemoradiotherapy, and was disease-free at the 8-month follow-up. True branchial cleft cyst carcinoma is rare: once diagnosed, it should be distinguished from metastatic cystic cervical lymph and occult primary carcinoma. FDG PET/CT is useful in the identification of occult primary tumor.

    Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.

    Purpose: Surgery is the primary treatment for adenoid cystic carcinomas arising from major and minor salivary glands of the head and neck. However, local recurrence is frequent because of the infiltrative growth pattern and perineural spread associated with these tumors. At UTMDACC, we have had a long-standing policy of using postoperative radiotherapy to reduce the risk of local recurrence and to avoid the need for radical surgery; this 30-year retrospective study analyzes the results of this combined modality approach. Methods and Materials: Between 1962 and 1991, 198 patients ages 13-82 years, with adenoid cystic carcinomas of the head and neck, received postoperative radiotherapy for known or suspected microscopic residual disease following surgery. Distribution of primary sites was: parotid: 30 patients; submandibular/sublingual: 41 patients; lacrimal: 5 patients; and minor salivary glands: 122 patients. Eighty-three patients (42%) had microscopic positive margins and an additional 55 (28%) had close (≤5 mm) or uncertain margins. One hundred thirty-six patients (69%) had perineural spread with invasion of a major (named) nerve in 55 patients (28%). Using radiation techniques appropriate to the primary site, a median dose of 60 Gy (range 50-69 Gy) was delivered to the tumor bed. Follow-up ranged from 5-341 months (median, 93 months). All surviving patients had a minimum of 2 years follow-up. Results: Twenty-three patients (12%) had local recurrences with 5-, 10-, and 15-year actuarial local control rates of 95%, 86%, and 79%, respectively. Fifteen of the 83 patients (18%) with positive margins developed local recurrences, compared to 5 of 55 patients (9%) with close or uncertain margins, and 3 of 60 patients (5%) with negative margins (p 0.02). Patients with and without a major (named) nerve involved had crude failure rates of 18% (10 out of 55) and 9% (13 out of 143), respectively (p 0.02). There was a trend toward better local control with increasing dose

    Cancers found in the resected branchial cleft cyst are rare clinically but usually impose substantive diagnostic and treatment challenges for clinicians. A 31-year-old man presented with a lateral neck mass that was suspected to be an inflammatory branchial cleft cyst. After excision, the pathologic specimen revealed a benign cystic appearance with a focus of undifferentiated carcinoma. Serologic tests for Epstein-Barr virus were negative. A positron emission tomography scan and upper aerodigestive tract endoscopies were negative for any other suspicious lesion. The patient underwent random biopsies of the nasopharynx, tongue base, and hypopharynx and bil tonsillectomy. Pathologic examination of the nasopharyngeal biopsies showed the presence of undifferentiated carcinoma. The cancerous part of the branchial cleft cyst and this nasopharyngeal specimen were positive for the latent membrane protein-1 and EBV-encoded RNAs of Epstein-Barr virus (EBV) and confirmed our diagnosis. This is the first report of a NPC metastasizing to a branchial cleft cyst. Molecular diagnostic techniques facilitate the definite diagnosis that enabled us to refine treatment plans and offered the patient a favorable outcome. Copyright © 2017 Elsevier B.V.

    Beclin 1 plays a critical role in autophagy and functions as a haploinsufficient tumor suppressor. The expression and prognostic significance of beclin 1 in head and neck adenoid cystic carcinoma (ACC) are largely unexplored. Therefore, we investigated the expression of beclin 1, Bcl-2, and p53 in head and neck ACC tissue. Tissue samples from 35 cases (15 females, 20 males) of head and neck ACC were utilized for immunohistochemistry. Beclin 1 expression was observed in 32 cases (91.4%) and considered to be high in 15 cases (42.9%) and low in 20 cases (57.1%). Beclin 1 expression was significantly correlated with a histological growth pattern (P=0.046) and histological grade (P=0.037). Beclin 1 expression was inversely correlated with Bcl-2 expression (P=0.013) and significantly associated with overall survival (P=0.006). Bcl-2 and p53 expression were observed in 21 cases (60.0%) and 16 cases (45.7%). Bcl-2 expression was significantly correlated with perineural invasion (P=0.041) and not associated with overall survival (P=0.053). p53 expression was directly correlated with beclin 1 expression (P=0.044). Our results indicated that beclin 1 may be a novel, promising prognostic factor for clinical outcome in head and neck ACC patients and may play a part in the development of head and neck ACC by interacting with Bcl-2 and p53.

    Full Text Available A 61-year-old female patient with adenoid cystic carcinoma (ACC of the right maxilla and Angle class II division 1 malocclusion had received a subtotal maxillectomy in right side and used a conventional clasp-retained obturator. After implants placement, a maxillary interim immediate obturator (IIO and then a definitive obturator using six endosseous implants were fabricated. During one-year follow-up, the patient was completely satisfied. Ideally, after implants placement in edentulous patients suffering from hemimaxillectomy, an implant-supported obturator (ISO is designed in order to prevent nasal reflux and to improve speech and swallowing. However, in the following case, because of skeletal class II division 1 malocclusion and implants insertion in the premaxilla, using an ISO was impossible because it would cause excessive upper lip protrusion and lack of anterior teeth contact. Therefore, a five-unit implant-supported fixed partial denture (FPD was fabricated in the maxillary anterior segment so that anterior teeth contacts were possible and the patient’s normal lip support was achieved. A bar and three ball attachments were used in the maxillary posterior segment. A closed-hollow-bulb ISO was preferred. Conventional ISO in these patients results in several problems. Using a maxillary anterior FPD along with ISO caused satisfactory results in the current patient.

    Yoshitsugu Mitani

    Full Text Available Salivary adenoid cystic carcinoma (ACC is a rare relentlessly progressive malignant tumor. The molecular events associated with ACC tumorigenesis are poorly understood. Variable microRNAs (miRNA have been correlated with tumorigenesis of several solid tumors but not in ACC. To investigate the association of miRNAs with the development and/or progression of ACC, we performed a comparative analysis of primary ACC specimens and matched normal samples and a pooled salivary gland standard and correlated the results with clinicopathologic factors and validated selected miRNAs in a separate set of 30 tumors.MiRNA array platform was used for the identification of target miRNAs and the data was subjected to informatics and statistical interrelations. The results were also collected with the MYB-NFIB fusion status and the clinicopathologic features.Differentially dysregulated miRNAs in ACC were characterized in comparison to normal expression. No significant differences in miRNA expression were found between the MYB-NFIB fusion positive and -negative ACCs. Of the highly dysregulated miRNA in ACC, overexpression of the miR-17 and miR-20a were significantly associated with poor outcome in the screening and validation sets.Our study indicates that the upregulation of miR-17-92 may play a role in the biology of ACC and could be potentially targeted in future therapeutic studies.

  19. Genetic profiling reveals cross-contamination and misidentification of 6 adenoid cystic carcinoma cell lines: ACC2, ACC3, ACCM, ACCNS, ACCS and CAC2.

    Directory of Open Access Journals (Sweden)

    Janyaporn Phuchareon

    Full Text Available Adenoid cystic carcinoma (ACC is the second most common malignant neoplasm of the salivary glands. Most patients survive more than 5 years after surgery and postoperative radiation therapy. The 10 year survival rate, however, drops to 40%, due to locoregional recurrences and distant metastases. Improving long-term survival in ACC requires the development of more effective systemic therapies based on a better understanding of the biologic behavior of ACC. Much preclinical research in this field involves the use of cultured cells and, to date, several ACC cell lines have been established. Authentication of these cell lines, however, has not been reported. We performed DNA fingerprint analysis on six ACC cell lines using short tandem repeat (STR examinations and found that all six cell lines had been contaminated with other cells. ACC2, ACC3, and ACCM were determined to be cervical cancer cells (HeLa cells, whereas the ACCS cell line was composed of T24 urinary bladder cancer cells. ACCNS and CAC2 cells were contaminated with cells derived from non-human mammalian species: the cells labeled ACCNS were mouse cells and the CAC2 cells were rat cells. These observations suggest that future studies using ACC cell lines should include cell line authentication to avoid the use of contaminated or non-human cells.

    Full Text Available Choledochal cyst is a relatively rare condition. Even rarer is a choledochal cyst in association with a gallbladder carcinoma. This study reports a rare case of gallbladder carcinoma coexisting with a choledochal cyst in a Nigerian patient. Clinical records of the patient including preoperative evaluation, intraoperative findings, and postoperative care were reviewed. A 38-year-old woman presented with the recurrent right upper abdominal pain of 3 years duration associated with progressive weight loss, anorexia, recurrent vomiting, as well as, low-grade fever with chills and rigors. Physical examination revealed an anicteric woman with tenderness in the right hypochondrium and a positive Murphy's sign. A combination of abdominal ultrasound and computed tomography scan suggested a Type IV choledochal cyst and a distended gallbladder with thickened walls containing a heterogeneous hyperdense mass. Preoperative serum alkaline phosphatase was elevated while endoscopic retrograde cholangiopancreatography was inconclusive. At laparotomy, extrahepatic biliary dilatation and enlarged, the nodular gallbladder was found with a diffusely fibrotic pancreas. Intraoperative cholangiogram confirmed Type IV choledochal cyst. Excision of the common bile duct and radical cholecystectomy was performed, and a Roux-en-Y hepaticojejunostomy. Histopathology confirmed the diagnosis of gallbladder adenocarcinoma. She had adjuvant chemotherapy and is presently on follow-up. No evidence of recurrence after 5 years of follow-up. A high index of suspicion is required to detect a combination of these two rare entities. When detected, both conditions should be surgically addressed at the same sitting, and when combined with adjuvant chemotherapy, may increase the chances of achieving a cure.

    Borderline ovarian tumors (BOTs) represent a heterogeneous group of ovarian epithelial neoplasms. Despite a favorable prognosis, 10-20% of BOTs exhibit progressively worsening clinic. Primary involvement of pelvic organs with echinococcus is very rare. Lymphoepithelioma-like gastric carcinoma is a rare neoplasm of the stomach. A 58-year-old woman referred with abdominal swelling and gastric complaints. Imaging studies revealed a huge cystic mass with multiple septations and solid component, another cystic mass with an appearance of cyst hydatid in the pelvis, and thickening of the small curvature of stomach. Gastroscopy revealed an ulcer with a suspicious malignant appearance, and histology of the endoscopic specimen showed severe chronic inflammation and lymphocytic infiltration. No other involvement of hydatid cyst was detected. In the exploration, there was a 25cm cystic lesion with solid components arising from right ovary, another 6cm cyst over the former, 7cm cystic lesion arising from left ovary, and 10cm mass near the small curvature of the stomach. Excision of the masses; total gastrectomy with esophagojejunal anastomosis; total abdominal hysterectomy; bilateral salpingo-oophorectomy; omentectomy; appendectomy; splenectomy; and pelvic, paraaortic, and coeliac lympadenectomy were performed. Final pathology revealed lymphoepithelioma-like gastric carcinoma, bilateral serous BOT, and hydatid cyst.

    Full Text Available Adenoid cystic carcinoma (ACC is an aggressive malignant neoplasm of the salivary glands in which c-Kit is overexpressed and activated, although the mechanism for this is as yet unclear. We analyzed 27 sporadic ACC tumor specimens to examine the biologic and clinical significance of c-Kit activation. Mutational analysis revealed expression of wild-type c-Kit in all, eliminating gene mutation as a cause of activation. Because stem cell factor (SCF is c-Kit's sole ligand, we analyzed its expression in the tumor cells and their environment. Immunohistochemistry revealed its presence in c-Kit–positive tumor cells, suggesting an activation of autocrine signaling. We observed a significant induction of ERK1/2 in the cells. SCF staining was also found in other types of non-cancerous cells adjacent to tumors within salivary glands, including stromal fibroblasts, neutrophils, peripheral nerve, skeletal muscle, vascular endothelial cells, mucous acinar cells, and intercalated ducts. Quantitative PCR showed that the top quartile of c-Kit mRNA expression distinguished ACCs from normal salivary tissues and was cross-correlated with short-term poor prognosis. Expression levels of SCF and c-Kit were highly correlated in the cases with perineural invasion. These observations suggest that c-Kit is potentially activated by receptor dimerization upon stimulation by SCF in ACC, and that the highest quartile of c-Kit mRNA expression could be a predictor of poor prognosis. Our findings may support an avenue for c-Kit-targeted therapy to improve disease control in ACC patients harboring the top quartile of c-Kit mRNA expression.

  4. Incidental Squamous Cell Carcinoma in an Epidermal Inclusion Cyst: A Case Report and Review of the Literature

    Full Text Available Epidermal inclusion cysts are common lesions that rarely develop into squamous cell carcinoma (SCC. Neoplastic change in these cysts can be associated with prominent symptoms such as pain, rapid growth, or ulceration. This study describes the case of a 64-year-old woman with a 4-year history of a largely asymptomatic neck mass, which after routine excision was found to be an epidermal inclusion cyst harboring well-differentiated SCC. The diagnosis was made incidentally after routine cyst bisection and hematoxylin and eosin staining. Given the potential for variable presentation and low cost of hematoxylin and eosin analysis, we recommend a low threshold for a comprehensive pathological search for malignancy in excised cysts when appropriate.

    Full Text Available Case summary A 9-year-old spayed female domestic shorthair cat was examined for swelling of the right upper lip. The cat had been receiving oral ciclosporin A for eosinophilic plaques. The swelling appeared clinically and cytologically consistent with an abscess; exudate was cultured and treatment consisted of antibiotic therapy and surgical curettage. Five months of antibiotic therapy with three separate surgical treatments resulted in minimal improvement; three separate biopsy samples demonstrated epithelial cysts with severe dermal inflammation. Swelling and drainage of purulent material from the affected lip persisted and progressed to involve the left upper lip. Euthanasia was elected 13 months after initial examination due to disease progression. On necropsy, histopathology demonstrated multiple isthmus cysts intermixed with squamous cell carcinoma (SCC. Relevance and novel information The clinical and histopathologic features were unusual for feline cutaneous SCC. The cystic nature and lack of epidermal involvement suggest the tumor arose from non-epidermal squamous cells such as follicular isthmus or ductal epithelium. There is a pattern of SCC recognized in human renal transplant patients with features of epidermal inclusion cysts. These features have not been previously reported in SCC from a cat.

    Full text: Total body scintigraphy after the I-131 treatment for thyroid carcinoma is a routine procedure in staging. For smaller tumors uptake outside the neck is seldomly seen, usually benign and without clinical significance. However, a conscientious analysis of there accumulations can be relevant. A 33 year-old female presented in December 1998 with a T2N1M0 papillary thyroid carcinoma. Thyroidectomy, neck dissection and 50 mCi 1-131 treated her. The post-therapy scan was negative except for a small spot in the neck (thyroidremnant: 3.0 %). In September 1999 150 mCi was administered and the scan afterwards showed a focus median in the neck (thyroid remnant: 0.3 %) and a persistent hotspot in the left lower quadrant of the abdomen (figure). The thyreoglobuline was 3.8 μg/l (unchanged to the first I-131 therapy) during maximal TSH Stimulation (174 mu/l). Transvaginal ultrasound revealed an enlarged left ovary which was laparoscopical removed and appeared to be a dermoid cyst with hair- and skincomponents, respiratory epithelia and bone. Only after staining on thyreoglobuline thyroid tissue was demonstrated; there were no signs of malignancy. Six months later a 10 mCi I-131 scintigraphy was negative; thyreoglobuline was < 0.5 μg/l and TSH 161 mg/l suggesting no thyroid tissue was present in the Body. Her medical history showed a polycystic ovary syndrome (PCOS). She received treatment for ovulation induction including clomiphene, HCG, FSH and LH. Her thyroid function was normal. After two miscarriages She gave birth to a daughter. Germ cells must been present since birth to form a dermoid cyst during life. In our patient, the dermoid cyst with benign thyroid cells was visualized only after the second I-131 therapy. We assume that the sensitivity of a scan after 50 mCi and 150 mCi I-131 is equal. Therefore, probably not the ovulation induction medication but the TSH stimulation for the I-131 therapy is the reason for the development of the dermoid cyst. That only

    The high frequencies of recurrence and distant metastasis of adenoid cystic carcinoma (AdCC) emphasize the need to better understand the biological factors associated with these outcomes. To analyze the mechanisms of AdCC metastasis, we established the green fluorescence protein (GFP)-transfected subline ACCS-GFP from the AdCC parental cell line and the metastatic ACCS-M GFP line from an in vivo metastasis model. Using these cell lines, we investigated the involvement of the epithelial–mesenchymal transition (EMT) and cancer stem cell (CSCs) in AdCC metastasis by real-time RT-PCR for EMT related genes and stem cell markers. Characteristics of CSCs were also analyzed by sphere-forming ability and tumorigenicity. Short hairpin RNA (shRNA) silencing of target gene was also performed. ACCS-M GFP demonstrated characteristics of EMT and additionally displayed sphere-forming ability and high expression of EMT-related genes (Snail, Twist1, Twist2, Slug, zinc finger E-box binding homeobox 1 and 2 [Zeb1 and Zeb2], glycogen synthase kinase 3 beta [Gsk3β and transforming growth factor beta 2 [Tgf-β2]), stem cell markers (Nodal, Lefty, Oct-4, Pax6, Rex1, and Nanog), and differentiation markers (sex determining region Y [Sox2], Brachyury, and alpha fetoprotein [Afp]). These observations suggest that ACCS-M GFP shows the characteristics of CSCs and CSCs may be involved in the EMT of AdCC. Surprisingly, shRNA silencing of the T-box transcription factor Brachyury (also a differentiation marker) resulted in downregulation of the EMT and stem cell markers. In addition, sphere-forming ability, EMT characteristics, and tumorigenicity were simultaneously lost. Brachyury expression in clinical samples of AdCC was extremely high and closely related to EMT. This finding suggests that regulation of EMT by Brachyury in clinical AdCC may parallel that observed in vitro in this study. The use of a single cell line is a limitation of this study. However, parallel data from in vitro and

    Background: Treatment of local relapse in adenoid cystic carcinoma (ACC) following prior radiation remains a challenge: without the possibility of surgical salvage patients face the choice between palliative chemotherapy and re-irradiation. Chemotherapy yields response rates around 30% and application of tumouricidal doses is difficult due to proximity of critical structures. Carbon ion therapy (C12) is a promising method to minimize side-effects and maximize re-treatment dose in this indication. We describe our initial results for re-irradiation in heavily pre-treated ACC patients. Methods: Patients treated with carbon ion therapy between 04/2010 and 05/2013 (N = 52 pts, median age: 54 a) were retrospectively evaluated regarding toxicity (NCI CTC v.4), tumour response (RECIST) and control rates. 48 pts (92.3%) received carbon ions only, 4 pts received IMRT plus C12. Results: 4 pts were treated following R1-resection, 43 pts for inoperable local relapse. Most common tumour sites were paranasal sinus (36.5%), parotid (19.2%), and base of skull (17.3%). Pts received a median dose of 51 GyE C12/63 Gy BED and cumulative dose of 128 Gy BED [67–182 Gy] after a median RT-interval of 61 months. Median target volume was 93 ml [9–618 ml]. No higher-grade (>°II) acute reactions were observed, 7 pts showed blood–brain-barrier changes (°I/II: 8 pts; °III: 2 pts), 1 pt corneal ulceration, xerophthalmia 7 pts, °IV bleeding 1 pt, tissue necrosis 2 pts, otherwise no significant late reactions. Objective response rate (CR/PR) was 56.6%. With a median follow-up of 14 months [1–39 months] local control and distant control at 1a are 70.3% and 72.6% respectively. Of the 18 pts with local relapse, 13 pts have recurred in-field, 1 pt at the field edge, 3 pts out of field, and one in the dose gradient. Conclusion: Despite high applied doses, C12 re-irradiation shows moderate side-effects, response rates even in these heavily pre-treated patients are encouraging and present a

    The separation of branchial cleft cysts from metastatic cystic squamous cell carcinomas in adults can be clinically and cytologically challenging. Diagnostic accuracy for separation is reported to be as low as 75% prompting some authors to recommend frozen section evaluation of suspected branchial cleft cysts before resection. We evaluated 19 cytologic features to determine which were useful in this distinction. Thirty-three cases (21 squamous carcinoma and 12 branchial cysts) of histologically confirmed cystic lesions of the lateral neck were graded for the presence or absence of 19 cytologic features by two cytopathologists. The cytologic features were analyzed for agreement between observers and underwent multivariate analysis for correlation with the diagnosis of carcinoma. Interobserver agreement was greatest for increased nuclear/cytoplasmic (N/C) ratio, pyknotic nuclei, and irregular nuclear membranes. Recursive partitioning analysis showed increased N/C ratio, small clusters of cells, and irregular nuclear membranes were the best discriminators. The distinction of branchial cleft cysts from cystic squamous cell carcinoma is cytologically difficult. Both digital image analysis and p16 testing have been suggested as aids in this separation, but analysis of cytologic features remains the main method for diagnosis. In an analysis of 19 cytologic features, we found that high nuclear cytoplasmic ratio, irregular nuclear membranes, and small cell clusters were most helpful in their distinction. Diagn.

    Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.

    Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed. A 36-year-old man presented with a solitary cystic cervical swelling, initially diagnosed as branchial cleft cyst. Fine needle aspiration yielded 18 ml of straw-coloured fluid. During cytological examination no atypical cells were observed. Computed tomography of the neck showed a heterogeneous mass with multiseptation medial to the sternocleidomastoid muscle. Histopathological examination of the mass, post excision, revealed a metastatic lymph node. A suspicious mucosal lesion at the nasopharynx was detected after repeated thorough head and neck examinations and the biopsy result confirmed undifferentiated nasopharyngeal carcinoma. Cystic cervical metastasis may occur in young patients under 40 years. The primary tumour may not be obvious during initial presentation because it mimicks benign branchial cleft cyst clinically. Retrospective review of the computed tomography images revealed features that were not characteristic of simple branchial cleft cyst. The inadequacy of assessment and interpretation had lead to the error in diagnosis and subsequent management. Metastatic head and neck lesion must be considered in a young adult with a cystic neck mass.

    Full Text Available Background: Adenoid hypertrophy is one of the most common health problems affecting the paediatric population. This study aims to correlate adenoidal nasopharyngeal ratio (ANR with symptoms of enlarged adenoids in children with enlarged adenoids. Materials and Methods: It was a year, cross-sectional, hospital-based study conducted at Lautech Teaching Hospital, Osogbo. ANR was determined by dividing adenoidal depth with nasopharyngeal depth on the plain lateral radiographs. Results: A total of 90 consecutive children consisting of 61 males and 29 females were included in the study with M:F ratio of 2.1:1. Their ages ranged from 8 months to 11 years. All the patients presented with nasal obstruction, mouth breathing and noisy breathing. Majority (64.5% had severe obstructions with preponderance among children of 3-5 years (39.9%. Linear regression analysis showed significant association between age and ANR (t = 10.447, P < 0.001. There was high significant association (P < 0.05 between presenting symptoms and degree of nasopharyngeal airway obstruction; for snoring (r = 0.251, P = 0.000, sleep apnoea (r = 0.594, P = 0.000, nasal discharge (r = 0.314, P = 0.001, excessive daytime sleepiness (r = 0.219, P = 0.019 and failure to thrive (r = 0.240, P = 0.011. Conclusion: Lateral X-ray of the nasopharynx is an effective tool to evaluate children with suspected adenoid hypertrophy. It correlates well with patients′ symptoms and provides objective measures of adenoid hypertrophy.

    Full Text Available Birt-Hogg-Dubé syndrome (BHD is a rare autosomal dominant inherited disease caused by a germline mutation in the folliculin gene mapped in the region of chromosome 17p11.2. BHD predisposes the patient to cutaneous fibrofolliculomas (FFs, pulmonary cysts (PCs, and renal cell carcinoma (RC. Here, we present two cases of BHD in Japanese patients. One patient was a 37-year-old female, and the other a 35-year-old male. Each of the patients was affected by all three symptoms of BHD. Both patients had unremarkable FFs, asymptomatic PCs, and asymptomatic RC. The presence of RC was revealed by abdominal ultrasonic examination. We also summarized the data from 62 Asian cases of BHD from the available literature and found that their FFs were unremarkable. In addition, the proportion of BHD patients with FF is smaller for Asian patients than it is for Caucasian patients. We also found that it is rare for BHD patients in Asia to show all three symptoms of BHD. Careful inspection of the skin as well as skin biopsies are important for the early detection of BHD cases in Asia.

    Adenoid is a kind of tonsil located in the posterior wall of the nasopharynx. Enlargement of the adenoid can produce obstruction of the nasopharynx and eustachian tube. Disturbance in discharge of nasal and paranasal secretions can be a cause of chronic rhinitis, sinusitis and otitis media. The diagnosis of enlarged adenoid by inspection is difficult due to its location. In the lateral roentgenogram of the skull the anterior wall of the adenoid is sharply delineated by air in the nasopharynx. The authors measured the sizes of adenoid and nasopharynx and calculated the adenoid-nasopharyngeal ratio (AN ratio) from 1,000 simple skull lateral roentgenograms of the children between the age of 0 to 16 years. Adenoid size is gradually increasing in the children up to 9 years of age but almost uncharged in the older age group. The AN ratio is highest in the age group of 8-9 years. In the age groups above 9 years of age the AN ratio is gradually decreased due to atrophic changes of the adenoid

    Biofilms of pathogenic bacteria are present on the middle ear mucosa of children with chronic otitis media (COM) and may contribute to the persistence of pathogens and the recalcitrance of COM to antibiotic treatment. Controlled studies indicate that adenoidectomy is effective in the treatment of COM, suggesting that the adenoids may act as a reservoir for COM pathogens. To investigate the bacterial community in the adenoid, samples were obtained from 35 children undergoing adenoidectomy for chronic OM or obstructive sleep apnea. We used a novel, culture-independent molecular diagnostic methodology, followed by confocal microscopy, to investigate the in situ distribution and organization of pathogens in the adenoids to determine whether pathogenic bacteria exhibited criteria characteristic of biofilms. The Ibis T5000 Universal Biosensor System was used to interrogate the extent of the microbial diversity within adenoid biopsy specimens. Using a suite of 16 broad-range bacterial primers, we demonstrated that adenoids from both diagnostic groups were colonized with polymicrobial biofilms. Haemophilus influenzae was present in more adenoids from the COM group (P = 0.005), but there was no significant difference between the two patient groups for Streptococcus pneumoniae or Staphylococcus aureus. Fluorescence in situ hybridization, lectin binding, and the use of antibodies specific for host epithelial cells demonstrated that pathogens were aggregated, surrounded by a carbohydrate matrix, and localized on and within the epithelial cell surface, which is consistent with criteria for bacterial biofilms.

    Radiotherapy treatment in childhood is an important cause of thyroid cancer. In the 1930 to 1950 era, radium irradiation of the nasopharynx was used to control hyperplastic adenoids. Because of the technical characteristics of this applicator, sufficient radiation was not applied to the thyroid by this technique to stimulate the development of thyroid malignancies. No malignancies have been reported thus far as a result of this treatment

    An amygdaloid cyst is a rare high laterocervical cystic tumor arising from the second branchial cleft. It accounts for 2% of laterocervical tumors and up to 85% of second branchial cleft abnormalities [1]. The incidence of intracystic squamous cell carcinoma ranges from 4 to 22% [2]. The diagnosis of primary carcinoma or intracystic metastasis is a controversial issue. We report a rare case of degenerate amygdaloid cyst meeting the diagnostic criteria for intracystic squamous cell carcinoma determined by Martin and Khafif. A 73-year-old female patient consulted for a left cervical swelling in 2010; the diagnosis was an amygdaloid cyst. She had a history of squamous cell carcinoma of the hard palate (T1NoMo) surgery and radiation therapy in 2009, without recurrence. Three years later, the swelling increased to a large size without any cervical node involvement. An exploratory cervicotomy with histological study revealed intracystic squamous cell degeneration. Primary squamous cell carcinoma location in the wall of an amygdaloid cyst is extremely rare and a highly controversial issue. The challenge is to be able to discriminate between a cystic metastasis of squamous cell carcinoma of the aerodigestive tract and a primary squamous cell carcinoma located in the wall of an amygdaloid cyst. Martin and Khafif defined specific criteria to confirm the diagnosis of primary branchiogenic carcinoma. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Background: There are several methods of evaluating adenoidal size pre-operatively. Plain nasopharyngeal radiography is a common investigative modality: it has been advocated, and also condemned. Aim: This study was intended to assess nasopharyngeal airway obstruction by the adenoids using plain X-rays; and also to find correlation if any, with the symptomatology. Methods: This is a retrospective study carried out between January and December 2008. The case notes and plain X-rays of the nasopharynx of 34 paediatric patients with clinical features of obstructive adenoids were analyzed. Results: A total of 34 children were studied, 22 (64.7%) were males and 12 (35.3%) were females. Their ages ranged between 7 months and 10 years: mean age was 3.55 years, standard deviation 2.723. Majority (67.6%) of the children were in the age group 0-4 years. The lowest symptomatology assessment score was 0 and the highest was 3. Children 4 years and below had the highest symptomatology scores. The minimum adenoidal-nasopharyngeal ratio was 0.35 and the maximum was 0.94. There was no significant difference in the mean adenoidal-nasopharyngeal ratio of males and females (t = 0.407; p = 0.692). Many (75.0%) of the children with moderate to severe nasopharyngeal airway obstruction by the adenoids were in the age bracket 0-4 years. The lowest adenoidal-nasopharyngeal ratio score was 0 and the highest was 3. Children 4 years and below had the highest adenoidal-nasopharyngeal ratio scores. There was a very weak nonsignificant correlation between the symptomatology assessment score and the radiological assessment score (r = 0.168; p = 0.375). Conclusion: The adenoidal-nasopharyngeal ratio is reliable in assessing the nasopharyngeal airway in children with obstructive adenoids.

    To describe characteristics of odontogenic cysts in a Mexican population. A retrospective study of 103 odontogenic cysts in 86 patients was done. The data were obtained from files of the Pathology Department of a General Hospital. We observed a frequency of the 8.13 % of odontogenic cysts (103) in 1266 pathological studies. The dentigerous cyst 56 % and odontogenic keratocyst 33 % were the most common odontogenic cysts. Sixty one percent of the cysts appeared in the second and third decades of life. In 71 cysts, 42 % appeared in the posterior region jaw, 29 % in the anterior region of the maxilla and 21 % in the posterior region of the maxilla. A 6.7 % developed a recurrence after treatment and a case of keratocyst of posterior region of the maxilla was associated with epidermoid carcinoma. The study included three women with the syndrome of carcinoma of the basal cell nevus, who presented multiple keratocysts. The dentigerous cysts and odontogenic keratocysts were the most frequent odontogenic cysts. They appeared mainly in the second and third decades of life.

    To evaluate the clinical usefulness of adenoid-nasopharynx ratio (A/N ratio) measured on nasopharyngeal lateral plain film, 106 clinical cases of secretory otitis media were selected to measure the A/N ratio before treatment. For patients with A/N ratio of 0.50-0.70, the symptoms improved distinctly after conservative treatment, but one half of patients with A/N ratio ≥ 0.71 required adenoidectomy. A/N ratio is a practical and convenient method for evaluation of the adenoid. A/N ratio ≥ 0.71 indicates pathological enlarged adenoid

    2011-09-01

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

    Although echinococcosis is not rare in South Africa, the location of a hydatid cyst in the thyroid is unusual. It usually presents as a solitary nodule, which may mimic a thyroid carcinoma. The routine use of aspiration cytology in the workup of cases of single thyroid nodules may complicate the further management of patients with a hydatid cyst of the thyroid; anaphylaxis and dissemination may occur and technical difficulties may be experienced during operation. A case of echinococcal cyst of the thyroid presenting as a single thyroid nodule, suspected to be thyroid cancer, is reported. 4 refs

    2016-01-01

    Full Text Available Odontogenic cysts are the most common form of cystic lesions that affect the maxillofacial region. The low frequency of dentigerous cysts in children has been reported in dental literature. Dentigerous cysts arise as a result of cystic change in the remains of the enamel organ after the process of enamel formation is complete. They enclose the crown of an unerupted tooth and are attached to the cementoenamel junction. Although most dentigerous cysts are considered developmental cysts, some cases seem to have an inflammatory origin. The purpose of this report is to present a case of an 8-year-old male patient with a dentigerous cyst of inflammatory origin.

  18. The adenoid: Its history and a cautionary tale.

    Science.gov (United States)

    Ruben, Robert J

    2017-06-01

    The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid. Removal of the adenoid became rapidly accepted worldwide as a treatment for many morbidities, including otitis, speech problems, cognitive problems, and sleep apnea. Until the 1920s, adenoidectomy often was performed as a staged procedure and without general anesthesia. Early tools and techniques included use of the bare fingernail, a finger ring knife, a curette, and electrical desiccation. From the mid-1930s to the early 1960s, radiation therapy of the adenoid was in extensive use, both for children and in caring for army aviators and navy submarine crews during WWII. The effectiveness of surgical adenoidectomy for hearing loss led to a belief that radiation, which had been found to ablate lymphoid tissue, would be equally effective, and led to the wide-spread use of radiation. Ultimately, 500 thousand to 2.5 million children and adults were estimated to have been treated with radiation, and follow-up studies found increased risk for cancer. Furthermore, a follow-up study by Stacey R. Guild (1890-1966), published in 1950, on a very large sample of children who previously were reported to have had their hearing loss diminished through radiation, found that irradiation had produced no effect on high-tone loss. Thus, irradiation was both useless and harmful. Acceptance of authority, which can lurk within medical culture, led to the development of a tragically misguided management of adenoid disease.

    2014-11-01

    Goltz-Gorlin syndrome presents with multiple basal cell carcinomas, odontogenic keratocysts, and cutaneous cysts, among other manifestations. The cutaneous cysts have been described as both epidermoid cysts and keratocysts but were not further characterized. Light microscopic examinations were made on 23 cutaneous cysts in 4 patients associated with Goltz-Gorlin syndrome located on extremities, face, trunk, palms, and soles and compared with nonsyndromic vellus hair cysts, steatocystomas, and hybrid cysts. Twenty-one of the syndromic cysts revealed alternating infundibular-like and steatocystoma-like squamous epitheliums in varying proportions. The cysts were lined by both smooth and corrugated squamous epithelium. The horny layer was composed by alternating areas of thin, lamellate, and compact eosinophilic keratin. Only 2 cases showed an exclusive steatocystoma-like type of epithelium very similar to odontogenic keratocysts. Sebaceous glands and follicular structures were absent. There were no differences between palmar and plantar cysts and other anatomic locations. The ultrastructural findings in syndromatic cysts confirmed variable expression of keratohyalin granules. Only 3 of 6 cases of nonsyndromic hybrid cysts showed overlapping features with syndromic cysts. Immunohistochemical profiling of keratin, involucrin, filaggrin, loricrin, and BCL-2 expression in syndromatic cysts showed exclusive positivity of K19 and continuous staining for BCL-2. In summary, 2 types of cutaneous cysts are characteristic of Goltz-Gorlin, irrelevant of their anatomic location, namely steatocystoma-like and more frequently hybrid-like. The diagnosis of syndromic hybrid-like cysts should be considered whenever infundibular and steatocystoma differentiation alternate and overlap. Altogether, these findings in epithelial cysts may raise the suspicion of Goltz-Gorlin as an underlying cause.

    From January 1967 through November 1991, a total of 135 patients with carcinoma of the major salivary glands (parotid: 95; submandibular: 39, sublingual: 1) were treated at our department. 40 patients had adenocarcinoma, 29 adenoid cystic carcinoma, 24 mucoepidermoid carcinoma and 16 squamous cell carcinoma. 100 patients were irradiated postoperatively and the remaining 35 were treated with radiation alone. Total radiation doses delivered were 50 Gy for the postoperative group and 50 to 66 Gy for the group receiving only radiation using a [sup 60]Co single portal with or without wedged paired or single electron portal boost. Actuarial five-year survivals after radiation therapy were 55% for the postoperative group and 26% for radiation only group (p=0.0004). The local control rates for the postoperative group were 83% for adenocarcinoma, 81% for adenoid cystic carcinoma, 83% for mucoepidermoid carcinoma and 62% for squamous cell carcinoma. Corresponding figures for the radiation only group were 40% for adenocarcinoma, 38% for adenoid cystic carcinoma and 33% for mucoepidermoid carcinoma. Conventional irradiation techniques continue to play an important role because they offer superior local control for postoperative patients with carcinoma of the major salivary glands. However, the local control rates for the radiation only group were only 30 to 40%, so that new irradiation modalities such as provided by a high LET machine are needed for these patients. (orig.)

    Adenoid hypertrophy and chronic adenoiditis are associated with an increased incidence of chronic otitis media. This study intends to determine the relationship between chronic otitis media and dynamic ciliary beat frequency in children undergoing adenoidectomy. Prospective, controlled study. Pediatric tertiary care hospital. Children undergoing adenoidectomy were enrolled. Patients were stratified according to their indication for surgery, including adenotonsillar hypertrophy with obstructive sleep apnea, chronic otitis media with effusion, or recurrent episodes of acute otitis media. Adenoids were harvested using the curette. Tissue was sectioned and allowed to equilibrate in basal media for 24 hours. Cilia-bearing tissue was then stimulated using isoproterenol or methacholine. Ciliary beat frequency was serially reordered and analyzed using the Sisson-Ammons Video Analysis software program. Baseline ciliary beat frequency was similar in all groups (N = 47, total). Using isoproterenol, children with chronic otitis media with effusion demonstrated a blunted dynamic ciliary response at 2 and 3 hours relative to control (P = .0176 and P = .0282). Methacholine-stimulated ciliary beat frequency was not different between each group. At 2 and 3 hours following isoproterenol stimulation, there was a significant blunting of dynamic ciliary beat frequency in children with chronic otitis media with effusion. This ciliary dysfunction may provide a physiological explanation related to chronic adenoiditis in children with chronic otitis media.

    Full Text Available Adenoid hypertrophy is a process in which adenoid size becomes enlarged and causes clinical symptoms, especially nasal obstruction. Adenoid hypertrophy can be due to physiological, inflammatory, or malignancy processes. Adenoid inflammatory process can be assessed using a flexible fiberoptic nasoendoscopy with narrow band imaging (NBI. Intranasal corticosteroid is one of the choices to treat adenoid hypertrophy in children; however, more experiments are needed to use it in adults. This study was performed in the period of November 2012 to January 2013 at the outpatient clinic of the Otorhinolaryngology-Head and Neck Surgery Department of Dr. Hasan Sadikin General Hospital Bandung, using pre- and post-test open-labeled quasiexperimental design. Sample was selected through consecutive sampling, involving 11 subjects. Diagnosis was based on research subject’s anamnesis, ear nose and throat (ENT physical examination, NBI-equipped fiberoptic nasoendocopy examination, and adenoid mucosal biopsy. Subjects were given intranasal corticosteroid therapy for four weeks. NBI-equipped fiberoptic nasoendocopy examination and biopsy examination were performed after therapy. Data were analyzed using Wilcoxon test, showing significant improvement of the adenoid inflammation after intranasal corticosteroids therapy (p<0.05. McNemar test results showed a significant reduction in adenoid size (p<0.05. Spearman rank test showed a significant correlation between histopathologic findings and NBI examination result (p<0.05. In conclusion, intranasal corticosteroids are effective for adult adenoid hypertrophy treatment based on NBI examination. [MKB. 2016;48(4:228–33

    1991-01-01

    This paper reports on the diagnosis of mediastinal foregut cysts which are difficult to establish even with CT, because these lesions often have high attenuation numbers similar to tumors. This study was undertaken to determine the value of MR imaging in the diagnosis of foregut cysts. MR imaging of 58 mediastinal masses was performed between 1986 and 1991 at 0.5 T, with T1- and T2-weighted images obtained. Seven foregut cysts were identified. Five were pathologically proven; in two cases the diagnosis was based on clinical findings and radiologic stability. Signal characteristics were compared with those of 52 pathologically proven mediastinal masses: six thymomas, 10 thyroid goiters and carcinomas, 11 neurogenic tumors, 15 lymphomas, and 10 miscellaneous masses. Fat and muscle were used as internal standards of signal intensity (SI). All foregut cysts were very bright on T2-weighted images. On T1-weighted sequences, two had low SI, but the remaining five showed high SI. These differences reflected variability in cyst protein content, high SI indicating the presence of mucus. On T1-weighted images, low SI was identified in most other mediastinal masses, but uniform high SI was specific for foregut cysts. Our series did not include any fatty lesions, as these were easily recognized on CT scans

    The odontogenic keratocysts had traditionally been considered as a developmental odontogenic cyst. The characteristics exhibited by this pathology such as its clinical behavior, the high rate of recurrence, its association with the syndrome nevoid basal cell carcinoma, high mitotic activity shown by the epithelial lining and the presence of 'cysts daughter' in capsule of fibrous connective tissue, as well as the discovery of genetic abnormalities caused the World Health Organization (WHO) reclassified as a benign neoplasm and will use the term odontogenic keratocyst tumor to name it.

    Full Text Available Epidermal inclusion cysts are uncommon in the breast, but the consequences can besevere when these cysts occur in the breast parenchyma. Here,we report two suchcases. The patient in case 1 was an 37-year-old woman with a 3-cm palpable mass inthe right breast. Mammography revealed a round and smoothly outlined mass, whichindicated a benign tumor, and sonography showed an irregularly shaped and heterogeneoushypoechoic mass, fibroadenoma was suspected on the basis of clinical andimage findings, but excisional biopsy revealed an epidermal inclusion cyst. The patientin case 2 was a 50-year-old woman with a 2.5-cm lesion in the left breast. Mammographyrevealed a round, dense, smoothly outlined mass, and sonography showeda well-defined, central hyperechoic mass. . Breast cancer was suspected on the basisof the sonographic findings and the age of the patient, but the resected specimen revealedan epidermal inclusion cyst. Although epidermal inclusion cysts are benign,occasionally they may play a role in the origin of squamous carcinoma of the breast. .Mammographic and sonographic features of an epidermal cyst may mimic a malignantlesion. Malignant change appears to occur more frequently in epidermal inclusioncysts in the mammary gland, compared to common epidermal inclusion cysts,and this may be associated with origination of mammary epidermal inclusion cystsfrom squamous metaplasia of the mammary duct epithelium.Epidermmoid inclusion cyst of the breast is potentially serious, although such cystsare rare, and differentiation from a malignant or benign breast tumor is required. Excisionis probably the most appropriate treatment, and can eliminate the possible riskof malignant transformation.

    The aim of this study was to investigate the health-related quality of life (HRQOL) in 5-7-year-old children diagnosed with adenoid hypertrophy and the impact of adenoid hypertrophy on affected families. This is a cross-sectional case-control study evaluating 5-7-year-old children with adenoid hypertrophy (n=195), 5-7-year-old healthy children (n=156), and associated caregivers (parents and/or grandparents). A Chinese version of the PedsQL™ 4.0 Generic Core Scale was used to assess childhood HRQOL, and a Chinese version of the Family Impact Module (FIM) was used to assess the impact of adenoid hypertrophy on family members. HRQOL scores were compared between the children with adenoid hypertrophy and healthy children. In addition, a multiple step-wise regression with demographic variables of children and their caregivers, family economic status, and caregiver's HRQOL as independent variables were referenced to determine the factors that may influence HRQOL in children with adenoid hypertrophy. Children with adenoid hypertrophy showed significantly lower physical, emotional, social, and school functioning scores than healthy children (pchildren with adenoid hypertrophy also scored significantly lower than caregivers for healthy children on physical, emotional, social, cognitive, and communication functioning (pchildren also exhibited significantly higher levels of worry than healthy children (pchildren's age, children's relation with caregivers, caregiver's educational level, caregiver's own HRQOL, and the size of adenoid may all influence the HRQOL in children with adenoid hypertrophy (pchildren and their caregivers, and may negatively influence family functioning. In addition, caregivers' social characteristics may also significantly affect the HRQOL in children with adenoid hypertrophy. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2013-10-07

    Orthokeratinised odontogenic cyst (OOC) denotes the odontogenic cyst that microscopically has an orthokeratinised epithelial lining. OOC is characterised by a less-aggressive behaviour and a low rate of recurrence. This report describes a case of OOC involving posterior part of the mandible that mimicked periapical cyst in a 14-year-old boy. The initial clinical diagnosis was given as periapical cyst based on the clinical and radiographical features. Enucleation of the cyst was performed and the specimen was sent for histopathological examination. A definite diagnosis of OOC was made by histopathological examination of the biopsy specimen. This case emphases on including OOC in the differential diagnosis of radiolucencies occurring in the periapical region of non-vital tooth.

    Duplication cyst of the gastrointestinal (GI) tract is a rare congenital anomaly, and rectal duplication cysts comprise a small fraction these cases. Most patients present for the first time in adulthood, and the origin of rectal duplication cysts is unclear. Prior series document malignant transformation in approximately 20 per cent of cases. The following case report describes a carcinoma arising in a rectal duplication cyst. Given the lack of data demonstrating adequate control for patients with adenocarcinoma arising in a rectal duplication cyst and our experience with this patient, we recommend all patients undergo multidisciplinary evaluation prior to any therapy.

  16. Management of ovarian cysts

    Knudsen, Ulla Breth; Tabor, Ann; Mosgaard, Berit Jul

    2004-01-01

    BACKGROUND: The treatment of an ovarian cyst relies on its nature, and accurate preoperative discrimination of benign and malignant cysts is therefore of crucial importance. This study was undertaken to review the literature concerning the preoperative diagnosis and treatment of ovarian cysts....... METHODS: Articles concerning ovarian cysts from a medline literature search during the period 1985-2003 were included in addition to articles found as references in the initial publications. RESULTS: Different methods for discriminating between benign and malignant ovarian cysts are discussed....... The diagnosis and the treatment are assessed in relation to age, menopausal status, pregnancy, and whether the cyst is presumed to be benign or malignant. In general, expectant management is the choice in premenopausal and pregnant women with non-suspicious cysts and normal levels of CA-125. In postmenopausal...

    Adenoid hypertrophy is a condition that presents itself as the chronic enlargement of adenoid tissues; it is frequently observed in the pediatric population. The Ugrp2 gene, a member of the secretoglobin superfamily, encodes a low-molecular weight protein that functions in the differentiation of upper airway epithelial cells. However, little is known about the association of Ugrp2 genetic variations with adenoid hypertrophy. The aim of this study is to investigate the association of single nucleotide polymorphisms in the Ugrp2 gene with adenoid hypertrophy and its related phenotypes. A total of 219 children, comprising 114 patients suffering from adenoid hypertrophy and 105 healthy patients without adenoid hypertrophy, were enrolled in this study. Genotypes of the Ugrp2 gene were determined by DNA sequencing. We identified four single nucleotide polymorphisms (IVS1-189G>A, IVS1-89T>G, c.201delC, and IVS2-15G>A) in the Ugrp2 gene. Our genotype analysis showed that the Ugrp2 (IVS1-89T>G) TG and (c.201delC) CdelC genotypes and their minor alleles were associated with a considerable increase in the risk of adenoid hypertrophy compared with the controls (p=0.012, p=0.009, p=0.013, and p=0.037, respectively). Furthermore, Ugrp2 (GTdelCG, GTdelCA) haplotypes were significantly associated with adenoid hypertrophy (four single nucleotide polymorphisms ordered from 5' to 3'; p=0.0001). Polymorfism-Polymorfism interaction analysis indicated a strong interaction between combined genotypes of the Ugrp2 gene contributing to adenoid hypertrophy, as well as an increased chance of its diagnosis (p<0.0001). In addition, diplotypes carrying the mutant Ugrp2 (c.201delC) allele were strongly associated with an increased risk of adenoid hypertrophy with asthma and adenoid hypertrophy with allergies (p=0.003 and p=0.0007, respectively). Some single nucleotide polymorphisms and their combinations in the Ugrp2 gene are associated with an increased risk of developing adenoid hypertrophy

    Borrás-Ferreres, Jordi; Sánchez-Torres, Alba; Gay-Escoda, Cosme

    2016-12-01

    The aim of this study was to systematically review scientific literature in orderto describe the characteristics and prognosis of malignant entities developing from odontogenic cysts. A search in Pubmed (MEDLINE) and Cochrane databases was conducted. The inclusion criteria were articles published in English related to the malignisation of odontogenic cysts in humans. The exclusion criteria were articles that do not specify the type of odontogenic cyst, malignisation of parakeratinised keratocysts, the presence of an ameloblastic carcinoma and metastasis from distant primary tumours. The selected articles were classified according to Strength of Recommendation Taxonomy criteria. Statistical analysis of the data was carried out using statistical package software SPSS version 22.0. From the 1,237 articles initially obtained, the authors included 3 case series and 45 case reports in the end. Descriptive analysis showed that men have a disposition for malignisation from odontogenic cysts and they frequently appear at the posterior mandible, with pain and swelling being the most frequent signs and symptoms. Follicular cysts were the entities that underwent the most malignant changes with well differentiated squamous cell carcinomas being the most prevalent type of malignancy. The real prognosis of this malignancy is not known because of the heterogeneity of available studies. Key words: Odontogenic cysts, squamous cell carcinoma, neoplastic cell transformation, oral cancer.

  1. Malignant Transformation Six Months after Removal of Intracranial Epidermoid Cyst: A Case Report

    Directory of Open Access Journals (Sweden)

    Fayçal Lakhdar

    2011-01-01

    Full Text Available Intracranial epidermoid cysts are uncommon benign tumors of developmental origin; malignant transformation of benign epidermoid cysts is rare, and their prognosis remains poor. We report a case of squamous cell carcinoma arising in the cerebellopontine angle. A 52-year-old man presented with left facial paralysis and cerebellar ataxia. He had undergone total removal of a benign epidermoid cyst six months previously. Postoperative magnetic resonance imaging of the brain revealed a heterogeneous and cystic lesion in the left cerebellopontine angle with hydrocephalus. The cyst wall was enhanced by gadolinium. He underwent ventricle-peritoneal shunt and removal again; the histopathological examination revealed a squamous cell carcinoma possibly arising from an underlying epidermoid cyst. This entity is being reported for its rarity. The presence of contrast enhancement at the site of an epidermoid cyst combined with an acute, progressive neurological deficit should alert the neurosurgeon to the possibility of a malignant transformation.

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

    2013-09-01

    To study the extent of surface adenoid biofilm and to evaluate its role in the pathogenesis of chronic otitis media with effusion (COME) in children. The study was carried out on 100 children between 3 and 14 years of age, who were divided into two groups. The first group (50 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (50 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. Microbiological study, Scanning electron microscope and multiplex- PCR were done for suspected adenoid biofilms and specimens from middle ear effusion. Adenoids removed from children with COME had higher grade biofilm formation (74 %) than the second group (42 %). No correlation was found between adenoid size and biofilm formation. Culture of adenoid tissue in group 1 patients was positive in 52 % of cases compared to 96 % by PCR, while in group 2 culture of adenoid tissue was positive in 38 % compared to 48 % by PCR. Culture of middle ear fluid was positive in 32 % of cases only compared to 80 % by PCR. A positive correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected and identified by PCR technique. On the other hand, no correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected by culture. The size of the adenoid is not the main determinant factor in OME pathogenesis but the degree of bacterial colonization is much more important. Adenoids in COME may act as a reservoir of chronic infection rather than causing mechanical Eustachian obstruction. Higher grade biofilm formation was found in cases with middle ear effusion than those with adenoid hypertrophy only. These findings support the hypothesis that there would be an association between adenoidal biofilm formation and COME. This study focused on the value of PCR

    Hydatid cyst disease is common in our part of the world. Cardiac hydatid cyst is its rare manifestation. We report this case of 48-year male having isolated cardiac hydatid cyst, incidentally found on computed tomography. This patient presented in medical OPD of Combined Military Hospital, Lahore with one month history of mild retrosternal discomfort. His general physical and systemic examinations as well as ECG were unremarkable. Chest X-ray showed an enlarged cardiac shadow with mildly irregular left heart border. Contrast enhanced CT scan of the chest showed a large well defined multiloculated non-enhancing cystic lesion with multiple daughter cysts involving wall of left ventricle and overlying pericardium. Serology for echinococcus confirmed the diagnosis of hydatid cyst. Patient was offered the surgical treatment but he opted for medical treatment only. Albendezol was prescribed. His follow-up echocardiography after one month showed no significant decrease in size of the cyst. (author)

    Full Text Available Dermoid cysts are a developmental benign choristomas, which are congenital lesions representing normal tissue/s in an abnormal location. These consist of ectodermal and mesodermal elements, lined with epithelium and contain hair with other skin structures. Periorbital dermoid cyst is commonly located at lateral one third of the eyebrow. It is asymptomatic however school going child suffers from social stigma. So its surgical excision for cosmetic purpose becomes necessary. Excision also prevents bony remoulding and recurrent inflammatory responses due to leakage of cyst contents. In this article we are presenting a six years old male child having periorbital dermoid in lateral right eyebrow. The intact dermoid cyst was excised surgically and sent for histopathological examination, which confirmed the diagnosis of dermoid cyst. We highlight the merits of early surgical intervention, even in an asymptomatic periorbital dermoid cyst.

    Calcified hemorrhagic adrenal cysts are rather rare and unusual pathologic entity. Especially, the peripheral curvilinear calcification on roentgenogram is fairly characteristic picture of the cysts. Recently, we have experienced in Severance Hospital one of the classical cases of the benign calcified adrenal cyst in 35 year old white mail patient who has had vague abdominal pain and palpable mass in right abdomen. It has been reviewed several reports for adrenal cysts and hoped that this report may call additional attention of radiological diagnosis on this unusual disease.

    Full Text Available INTRODUCTION: There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp in adenotonsillar tissue. OBJECTIVE: A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. METHODS: Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction. RESULTS: Hp IgG was detected in 57 (89% patients' serum. A total of seven tissue samples from 64 patients (10.9% were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. CONCLUSION: This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas.

    2017-04-01

    Full Text Available Congenital hepatic cyst is a rare and nonsymptomatic condition in infants and children. Its incidence is 2.5% in the postnatal life with a much lower incidence in the prenatal period. Incidental finding on antenatal imaging is the most common presentation. We present a case of a newborn in whom fetal ultrasound detected a cyst within the fetal liver. Postnatal imaging revealed a liver cyst in the right lobe of the liver, with no other intrahepatic structure affected. Liver function tests were abnormal, but the patient was asymptomatic. Posterior follow-up imaging showed a minor decrease in size. Management of congenital hepatic cyst is usually conservative, done with periodic ultrasound monitoring. However, surgical treatment is the mainstay of treatment when hydrops, progressive enlargement, hemorrhage, torsion, or compression of adjacent structures occurs. Malignant transformation can occur, but it is extremely rare. Partial or total removal of the cyst is the preferred treatment in neonates with a large lesion.

    Cysts of spleen are rare entities. Congenital splenic cysts are even more uncommon comprising of only 10% of benign non-parasitic cysts. We report a case of 22 years old female who presented with history of 2 years abdominal pain and gradual distension. Ultrasound and computed tomography (CT) both were suggestive of splenic cyst. Laboratory tests show thrombocytopenia with platelets count of 97000 per cubic millimeter and anemia with hemoglobin 8.7 gram per deciliter. Serological tests were negative for parasitic infection. Splenectomy was done and the weight of the spleen was found to be 1.5 kilogram. Histopathological findings are consistent with splenic epithelial cyst. The aetiology, diagnostic modalities and treatment options are discussed in the case report. (author)

    A 39-year-old woman was admitted to hospital with headaches, vomiting, psychic impairment and diplopia. Three hydatid cysts of the lung had been previously removed. An avascular mass in the left hemisphere with left-to-right displacement of the anterior cerebral arteries was noted during a brain angioscintigraphy. A cerebralthrombosis (CT) brain scan showed two cystic lesions situated in the left-frontal and occipital regions. A CT abdominal scan showed multiple cysts in the liver, spleen and both kidneys. At operation, two brain cysts were totally extirpated without rupture. The definite pathological diagnosis was secondry hydatid cysts. The headaches, vomiting and diplopia were persistent in the post-operative period. Seven days after the operation, a CT brain scan showed an infratenrorial cyst. The patient rejected any surgical intervention.

  14. ON THE ROLE OF BACTERIAL MICROFLORA IN ETIOLOGY OF CHRONIC ADENOIDITIS IN CHILDREN

    Directory of Open Access Journals (Sweden)

    D. A. Tulupov

    2014-01-01

    Full Text Available A review of the results of clinical studies on the role of pathogenic bacterial microflora in etiology of chronic adenoiditis in children is shown in this article. According to the literature data the main cause of the development of chronic diseases of the nasopharynx in children is viral infection. The role of the bacterial microflora is secondary, but nevertheless significant. The main bacterial pathogens isolated from the nasopharynx of children with chronic adenoiditis are Staphylococcus aureus, Haemophilus influenzae and Streptococcus pneumonia. However there is significant dissociation in the prevalence of these bacterial agents according to the data of different scientists. Ability of the bacteria to produce biomembranes plays significant role in formation of persistence of the above-mentioned pathogens in the nasopharynx in chronic adenoiditis. Bacterial biomembranes as well as the revealing of the large amounts of bacteria within the tissues of adenoids determines discussions on possibilities of systemic and topical antibacterial treatment.

    2015-01-01

    Full Text Available Odontogenic cysts may occur in association with odontogenic tumors. Because neoplastic and hamartomatous aberrations can occur at any stage of odontogenesis, combined features of odontogenic tumors with epithelial and mesenchymal components may arise within odontogenic cysts. One of the most common of these is dentigerous cyst (DC which has neoplastic potential and shows associated pathologies such as ameloblastoma, squamous cell carcinoma, mucoepidermoid carcinoma (MEC, adenomatoid odontogenic tumor (AOT, and odontoma. The authors report four cases of DC and associated lesions exhibiting AOT in two cases while one case each of complex odontome and MEC. Emphasis is placed on pathogenesis and clinicopathologic features of these lesions.

    The fallen fragment sign is a prominent radiologic feature in a minority of cases of unicameral bone cyst (20% in this series). This sign is always associated with pathologic fracture. Intramedullary fracture fragments may be single or multiple and may or may not be entirely dislodged from overlying periosteum. The finding appears limited to unicameral bone cysts in patients with open physes. When present, the fallen fragment is a pathognomonic finding as it defines the interior of the cyst as nonsolid.

    We present the case of a child with chronic adenoiditis caused by a PspK+ NESp. We tested the pneumococcal isolate, designated C144.66, for antimicrobial resistance, the presence of the pspK gene and the expression of PspK. Sequence typing and genome sequencing were performed. C144.66 was found to be resistant to erythromycin and displayed intermediate resistance to penicillin and trimethoprim/sulfamethoxazole. C144.66 has the pspK gene in place of the capsule locus. Additionally, PspK expression was confirmed by flow cytometry. NESp are a growing concern as an emerging human pathogen, as current pneumococcal vaccines do not confer immunity against them. An inability to vaccinate against NESp may result in increased carriage and associated pathology.

    Glandular odontogenic cysts (GOCs) are rare intrabony solitary or multiloculated cysts of odontogenic origin. The importance of GOCs lies in the fact that they exhibit a propensity for recurrence similar to keratocystic odontogenic tumors and that they may be confused microscopically with central mucoepidermoid carcinoma. Thus, the oral and maxillofacial radiologists play an important role in definitive diagnosis of GOC based on distinctive cases; though they are rare. In large part, this is due to the GOC's complex and frequently non-specific histopathology. This report describes a case of GOC occurrence in the posterior mandibular ramus region in a 17-year-old female, which is a rare combination of site, age, and gender for occurrence.

    Full Text Available Background: Mesenchymal stromal cells (MSCs are multipotent progenitor cells that originally derived from bone marrow. Clinical use of bone marrow-derived MSC is difficult due to morbidity and low MSC abundance and isolation efficiency. Recently, MSCs have been isolated from various adult tissues. Here we report the isolation of adenoid tissue-derived MSCs (A-MSCs and their characteristics. Methods: We compared the surface markers, morphologies, and differentiation and proliferation capacities of previously established tonsil-derived MSCs (T-MSCs and bone marrow-derived MSCs (BM-MSCs with cells isolated from adenoid tissue. The immunophenotype of A-MSCs was investigated upon interferon (IFN-γ stimulation. Results: A-MSCs, T-MSCs, and BM-MSCs showed negative CD45, CD31 HLA-DR, CD34, CD14, CD19 and positive CD 90, CD44, CD73, CD105 expression. A-MSCs were fibroblast-like, spindle-shaped non-adherent cells, similar to T-MSCs and BM-MSCs. Adipogenesis was observed in A-MSCs by the formation of lipid droplets after Oil Red O staining. Osteogenesis was observed by the formation of the matrix mineralization in Alizarin Red staining. Chondrogenesis was observed by the accumulation of sulfated glycosaminoglycan-rich matrix in collagen type II staining. These data were similar to those of T-MSCs and BM-MSCs. Expression of marker genes (i.e., adipogenesis; lipoprotein lipase, proliferator-activator receptor-gamma, osteogenesis; osteocalcin, alkaline phasphatase, chondrogenesis; aggrecan, collagen type II α1 in A-MSCs were not different from those in T-MSCs and BM-MSCs. Conclusions: A-MSCs possess the characteristics of MSCs in terms of morphology, multipotent differentiation capacity, cell surface markers, and immunogeneity. Therefore, A-MSCs fulfill the definition of MSCs and represent an alternate source of MSCs.

    Authors described a case of 60 year-old woman with multiple lateral neck cysts. 4 cysts were located in the supraclavicular region of lateral neck triangle. During histopathological studies of postoperative specimens a cystic hygroma diagnosis was established. The fact, that cystic lymphangioma occurred in an adult woman, was interesting. The authors stress the necessity of preoperative evaluation of tumor size in view of the possibility of its penetration into the thorax. The CT examination may be useful in these cases. (author)

    A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used. (author)

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

    Simple bone cysts (SBC) are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid. In jaws initially it mimics a periapical cyst and later can lead to cortical bone expansion warranting for radical approach, which is seldom required. SBC is predominantly diagnosed in first two decades of life. Here we report a case of solitary bone cyst mimicking a periapical cyst of a mandibular molar in a 37-year-old patient.

    Epidermoid cysts are lesions, which form as a result of implantation of the epidermis in the layers of the dermis or the mucous membrane. The lesions are rare in adults with 7% occurring in the head and neck area and most often located in the submental region. In children population submental epidermoid cysts are extremely rare. The differential diagnosis of the lesions is necessary as it affects the choice of treatment methods. Among the pathological conditions occurring in that region, salivary retention cyst (ranula), thyroglossal duct cyst, vascular lymphatic malformation (cystic hygroma), median neck cyst, lymphadenopathy, thyroid gland tumor, laryngeal cyst, epidermoid and dermoid cysts, submental abscess, sialolithiasis and salivary gland inflammation should be considered. The authors of the present report demonstrate two cases of submental epidermoid cysts in children. Differential diagnosis in case of suspected submental epidermoid cyst in a child with proposed clinical practice and literature review is provided.

    Primary posterior mediastinal hydatid cyst is a serious health problem for the Mediterranean countries. We diagnosed a case of a 46-year-old female with a primary posterior mediastinum hydatid cyst on CT and MRI. It was provisionally identified as either a hydatid cyst or bronchogenic cyst or neuroenteric cyst. CT guided aspiration with 18 gauge needle confirmed as hydatid sand. This is very rare in this population but it should be kept in mind when one is looking at any cyst in the posterior mediastinum. (author)

    Accurate preoperative staging of ovarian chocolate cysts is very important because recent hormonal therapy has been effective in low stage patients. However, it has been difficult to assess the preoperative stage of ovarian chocolate cysts. We evaluated the diagnostic potential of MRI in preoperative staging of 15 overian chocolate cysts. It was well known that the older the ovarian chocolate cyst was the more iron content it had. We examined the iron contents effect on T1 and T2 relaxation times in surgically confirmed chocolate cysts (stage II: 3 cases, stage III: 3 cases and stage IV: 9 cases by AFS classification, 1985) employing the 0.15-T MR system and 200 MHz spectrometer. There was a positive linear relation between T1 of the lesion using the MR system (T1) and T1 of the resected contents using the spectrometer (sp-T1); r = 0.93. The same relation was revealed between T2 and sp-T2; r = 0.87. It was indicated that T1 and T2 using the MR system was accurate. There was a negative linear relation between T1 and the iron contents ( r = -0.81) but no relation between T2 and the iron contents. T1 was 412 ± 91 msec for stage II, 356 ± 126 msec for stage III and 208 ± 30 msec for stage IV. T1 for stage IV was shorter than that for stage II and III, statistically significant differences were noted (p < 0.05). Thus, T1 was useful in differentiating a fresh from an old ovarian chocolate cyst. We concluded that T1 relaxation time using the MR system was useful for the staging of an ovarian chocolate cyst without surgery. (author)

    Full Text Available Introduction: One of the major causes of pediatric morbidity today at the community level is infection involving the ear, nose, and throat. Maximum of these patients respond well initially on general regular medications, but then recurrent complaints are not very uncommon. One of the major causes for such recurrence is hypertrophy of adenoids, the evaluation of which requires a battery of sophisticated investigative tools and expertise which are lacking at the community level. The aim of the study is to evaluate various symptoms related to adenoid hypertrophy and its correlation to the size of the adenoid seen in the lateral view nasopharyngeal X-ray. The aim of the study was to assess various symptoms related to adenoid hypertrophy and its correlation with the size of adenoid radiologically. Methods: A total of fifty cases of pediatric age with strong clinical suspicion of adenoid hypertrophy were included in the study. Through ENT examination was done. X-ray lateral view nasopharynx was obtained. Results: Adenoid hypertrophy was graded according to symptoms score and lateral cephalometric/radiographs. Snoring was the most frequent symptom which had a linear relation with the size of the adenoid. Conclusion: There was good agreement between symptom and the X-ray findings.

    Twenty-six children with obstructive sleep apnea were evaluated by lateral neck radiographs during wakefulness, and by polygraphic monitoring and upper airway fluoreoscopy during natural sleep. Children with craniofacial abnormalities, palatal surgery, and central nervous system disease were excluded from the study. Moderate or marked enlargement of tonsils and adenoids was noted on lateral neck radiographs of 18 of 26 patients. An objective measure of adenoidal enlargement, the adenoidal-nasopharyngeal ratio, correlated well with subjective judgment of adenoidal size but was not generally more useful than subjective estimation. Upper airway fluroescopy demonstrated the site and mechanism of obstruction in all patients. Because all children with moderate to marked adenotonsillar enlargement demonstrated obstruction at the adenoidal or tonsillar level on fluoroscopy, we now screen children with suspected sleep apnea with lateral airway radiographs and polysomnography. Fluoroscopy is reserved for children with mild adenotosillar enlargement, craniofacial dysplasia, prior cleft palate repair, or neuromuscular disorders. These results suggest that the pathogenesis of obstuctive sleep apnea in children involve anatomic factors which narrow the upper airway, sleep-related hypotonia of pharyngeal dilator musculature, and compensatory mechanisms to prevent or alleviate asphyxia.

Between 2001-2002, 25 patients with chronic adenoitis and chronic secretory otitis media and 25 patients with isolated adenoid hypertrophy were included to the study. Adenoidectomy performed to the all patients under general anesthesia. Adenoidectomy specimens were evaluated under the light microscopy and the number of mast cells were calculated for each patient. The number of mast cells were compared between two groups. The number of mast cells were between 4-84 in the otitis media with effusion and adenoid hypertrophy group (median:52, however it was between 2-63 (median: 23 in the isolated adenoid hypertrophy group. When comparing the two groups using Mann-Withney U test, the number of mast cells found to be significantly higher in the chronic secretory otitis media group (p<0.001.Based on our findings there is a relationship between increased adenoid mast cells and otitis media with effusion and these cells may have a possible role in the etiology of chronic secretory otitis media.

    2006-09-01

    Since their original description by Virchow, simple bone cysts have been studied repeatedly. Although these defects are not true neoplasms, simple bone cysts may create major structural defects of the humerus, femur, and os calcis. They are commonly discovered incidentally when x-rays are taken for other reasons or on presentation due to a pathologic fracture. Various treatment strategies have been employed, but the only reliable predictor of success of any treatment strategy is the age of the patient; those being older than 10 years of age heal their cysts at a higher rate than those under age 10. The goal of management is the formation of a bone that can withstand the stresses of use by the patient without evidence of continued bone destruction as determined by serial radiographic follow-up. The goal is not a normal-appearing x-ray, but a functionally stable bone.

  4. Bone cysts: unicameral and aneurysmal bone cyst.

    Science.gov (United States)

    Mascard, E; Gomez-Brouchet, A; Lambot, K

    2015-02-01

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    To report our experience and review published reports on the laparoscopic management of peripelvic renal cysts. Peripelvic renal cysts represent a unique subset of renal cysts, as they are rare, commonly symptomatic, and more difficult to treat than simple peripheral renal cysts. Minimally invasive methods for the treatment of peripelvic renal cysts, including laparoscopic decortication, have recently become more common. Four patients who presented with symptomatic peripelvic cysts underwent laparoscopic decortication at our institution. All four were men aged 47 to 65 years. One patient had undergone an unsuccessful prior cyst aspiration. All patients underwent preoperative computed tomography and retrograde pyelography. The mean number of peripelvic cysts per patient was 3.0, and the mean cyst size was 7.1 cm. The mean operative time was 259 minutes (range 240 to 293), and the mean estimated blood loss was 30 mL (range 10 to 50). No evidence of cystic renal cell carcinoma was found on aspiration cytology or cyst wall pathologic examination. The mean hospital stay was 1.3 days. No inadvertent collecting system injuries and no intraoperative or postoperative complications occurred. All 4 patients achieved symptomatic relief and were determined to have radiologic success as determined by the 6-month postoperative computed tomography findings. Laparoscopic ablation of peripelvic renal cysts is more difficult than that of simple peripheral renal cysts and demands a heightened awareness of potential complications and, therefore, more advanced surgical skills. In addition to our experience, a thorough review of published reports found this procedure to be safe and effective with appropriate patient selection.

    Ectopy is the most common embryogenetic defect of the thyroid gland, representing between 48 and 61% of all thyroid dysgeneses. Persistence of thyroid tissue in the context of a thyroglossal duct remnant and lingual thyroid tissue are the most common defects. Although most cases of ectopic thyroid are asymptomatic, any disease affecting the thyroid may potentially involve the ectopic tissue, including malignancies. The prevalence of differentiated thyroid carcinoma in lingual thyroid and thyroglossal duct cyst is around 1% of patients affected with the above thyroid ectopies. We here review the current literature concerning primary thyroid carcinomas originating from thyroid tissue on thyroglossal duct cysts and lingual thyroid. Copyright © 2016 SEEN.

    The present study aimed to investigate the probable differences in cell proliferation index of odontogenic cysts and tumors by means of a comparative silver stained nucleolar organizing region (AgNOR) quantification. This descriptive cross-sectional study was done on archival paraffin blocks (n = 62), consisting of 10 odontogenic keratocysts, 10 dentigerous cysts, 10 radicular cysts, 10 conventional ameloblastomas, 10 adenomatoid odontogenic tumors, 10 calcifying epithelial odontogenic tumors and 2 ameloblasic carcinomas. The mean AgNOR count of odontogenic cysts was 1.709 and the benign odontogenic tumors was 1.862. Highest AgNOR count was recorded in odontogenic keratocyst and lowest was seen in radicular cyst. Statistically significant difference in AgNOR counts of ameloblastoma and adenomatoid odontogenic tumor, amelobalastoma and calcifying epithelial odontogenic tumor, benign odontogenic tumors and ameloblastic carcinoma were seen. AgNORs in ameloblastic carcinoma were more in number and more widely spread. AgNOR technique may be considered a good indicator of cell proliferation in odontogenic cysts and tumors.

    Full Text Available Primary intraosseous carcinoma of the jaws (PIOSCC might arise from odontogenic epithelium, more commonly from a previous odontogenic cyst. The aim of this case is to illustrate that the clinician should consider that an apparent benign dentigerous cyst can suffer malignant transformation and that all material removed from a patient must be evaluated histologically. A 44-year-old man presented in a routine periapical X-ray an impacted lower left third molar with radiolucency over its crown. Ten years later, the patient complained of pain in the same region and the tooth was extracted. After one month, the patient still complained of pain and suffered a fracture of the mandible. A biopsy was performed and carcinoma was diagnosed. The patient was treated surgically with adjuvant radio- and chemotherapy and after 8 years, he is well without signs of recurrences. This report describes a central mandibular carcinoma probably developed from a previous dentigerous cyst.

    Full Text Available Squamous cell carcinoma of the ovary is a rare condition and usually arises in mature cystic teratoma (MCT or dermoid cyst of the ovary. The reported incidence of malignant transformation in MCT is approximately 2%. A case of squamous cell carcinoma arising in a dermoid cyst of the ovary presenting at an early stage is presented here. A 53-year-old postmenopausal lady, presented with the complaint of pain in right lower abdomen since one month and a large complex abdomino-pelvic mass on examination and investigations. Final histopathology was reported as squamous cell carcinoma of left ovary arising from dermoid cyst and a benign dermoid cyst in the right ovary. The patient was assigned to squamous cell carcinoma of the ovary arising in a mature cystic teratoma, surgical stage Ic2. In view of the poor prognosis, adjuvant chemotherapy was started.

    A 37-year-old yellow-crowned Amazon parrot (Amazona ochrocephala) and a 20-year-old red-lored Amazon parrot (Amazona autumnalis) each presented with a large mass localized on the lateral neck. With the first bird, there was no evidence of signs of pain or discomfort, and the bird prehended and swallowed food normally. The second bird showed signs of mild upper-gastrointestinal discomfort. Results of an ultrasound examination and aspiration of the mass on each bird revealed a cystic structure. A computed tomography performed on the second bird revealed a large polycystic mass connected to the pharynx by a lateral tract. During surgical resection, both masses were found to originate from the subpharyngeal area. Based on topography and the histopathologic and immunohistochemical results, the masses were determined to be a second branchial cleft cyst for the first case and a second branchial pouch cyst for the second case. In addition, a carcinoma was present in situ within the epithelium of case 1, and the cyst in case 2 was secondarily infected. Branchial cysts are uncommonly diagnosed in veterinary and human medicine. These 2 cases are the first documented in parrots and appear similar to second branchial cysts reported in adult humans.

    To compare the skeletal features of subjects with adenoid hypertrophy with those of children with tonsillar hypertrophy using thin-plate spline (TPS) analysis. A group of 20 subjects (9 girls and 11 boys; mean age 8.4 ± 0.9 years) with adenoid hypertrophy (AG) was compared with a group of 20 subjects (10 girls and 10 boys; mean age 8.2 ± 1.1 years) with tonsillar hypertrophy (TG). Craniofacial morphology was analyzed on the lateral cephalograms of the subjects in both groups by means of TPS analysis. A cross-sectional comparison was performed on both size and shape differences between the two groups. AG exhibited statistically significant shape and size differences in craniofacial configuration with respect to TG. Subjects with adenoid hypertrophy showed an upward dislocation of the anterior region of the maxilla, a more downward/backward position of the anterior region of the mandibular body and an upward/backward displacement of the condylar region. Conversely, subjects with tonsillar hypertrophy showed a downward dislocation of the anterior region of the maxilla, a more upward/forward position of the anterior region of the mandibular body and a downward/forward displacement of the condylar region. Subjects with adenoid hypertrophy exhibited features suggesting a more retrognathic mandible while subjects with tonsillar hypertrophy showed features suggesting a more prognathic mandible.

    We studied 37 intradiploic epidermoid cysts, reviewing typical and atypical radiological features and the differential diagnosis. The most common clinical feature was a long standing lump in the scalp, occurring in 25 patients (67.7 %). Plain films were the most cost-effective radiological technique in diagnosis. The typical finding was a well-defined lytic lesion with sclerotic border, seen in 29 cases (78 %). Atypical lesions were those larger than 5 cm and/or with an ill-defined edge, being observed in 8 cases (22 %). CT and MRI were the best methods for assessing atypical ones. In all cases with typical radiological findings a preoperative diagnosis of intradiploic epidermoid cyst was suggested. (orig.). With 8 figs., 3 tabs

    The high-resolution ultrasound has taken to discover small ovary cysts in postmenopausal asymptomatic women who in another situation would not been detected; these cysts frequently disappear spontaneously and rarely develop cancer; however, they are treated aggressively. To know the prevalence, evolution and treatment of ovary simple cysts in the postmenopausal women in our department, since in our country there are not studies that had analyzed these data. We made a retrospective and descriptive study in the Service of Biology of the Human Reproduction of the Hospital Juarez de Mexico, in a four-year period (2000-2003) that included 1,010 postmenopausal women. The statistical analysis was made using the SPSS software program with which we obtained descriptive measurements in localization, dispersion and by a graphic analysis. We found a simple cysts prevalence of 8.2% (n = 83); the average of age at the diagnosis time was 50.76 years with a standard deviation of 5.55; the cysts diameter was between 0.614 to 12,883 cm with a mean and standard deviation of 2.542 and 1.91 cm respectively; in 27.71% of the cases (n = 23), the cysts disappear spontaneously in the follow up of 3 to 36 month (mean of 14.1). Surgery was indicated in 16.46% (n = 13), by increase in the size of the cyst in 9 patients (11.64%) and by changes in morphology from simple to complex in 4 (4.82%). Tumor like markers were made only to 37 patients (44.57%), which were in normal ranks; no carcinoma was found in this group. The prevalence of ovary simple cysts was similar to the reported in literature. Risk of cancer of these cysts is extremely low when a suitable evaluation is made, a reason why the conservative treatment is suggested when these are simple cysts lesser than 5cm with Ca-125 levels within normal ranks. We recommend a follow up every 3-6 months by Doppler color ultrasound and tumor like markers for five years.

    2015-01-01

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings.

    Hydatid cyst disease most commonly affects liver and lungs, but it can affect all viscera and soft tissues of the body. Simultaneous mammary and femoral hydatid cysts, without any other visceral involvement, are extremely rare. This is a case report of 25-years-old female, presenting with lump in left breast mimicking fibroadenoma and lump in right thigh mimicking fibroma. Both turned out to be hydatid cysts.

    Full Text Available This study presents the treatment of 68 children with secretory otitis media. Children underwent adenoid vegetations, nasal speech, conductive hearing loss, ventilation disturbance in Eustachian tube. In all children adenoidectomy was indicated.38 boys and 30 girls at the age of 3-17 were divided in two main groups: * 29 children without hypertrophic (enlarged adenoids, * 39 children with enlarged (hypertrophic adenoids.The surgical treatment included insertion of ventilation tubes and adenoidectomy where there where hypertrophic adenoids.Clinical material was analyzed according to hearing threshold, hearing level, middle ear condition estimated by pure tone audiometry and tympanometry before and after treatment. Data concerning both groups were compared.The results indicated that adenoidectomy combined with the ventilation tubes facilitates secretory otitis media heeling as well as decrease of hearing impairments. That enables prompt restoration of the hearing function as an important precondition for development of the language, social, emotional and academic development of children.

    2015-03-01

    The purpose of this report is to document the clinical, radiographic, pathological and molecular findings of the first case of multiple orthokeratinized odontogenic cysts (OOCs). Multiple odontogenic keratocysts are one of the major features of nevoid basal cell carcinoma syndrome (NBCCS), and loss of heterozygosity in the PTCH gene, the culprit gene for NBCCS, has recently been found in sporadic OOC cases. Therefore, in this presenting case, we also investigated the possibility that this patient might also have NBCCS, by comparing the available clinical information and the molecular findings of this case to the diagnostic criteria for NBCCS (as proposed by the First International Colloquium on NBCCS in 2011). However, this patient with multiple OOCs showed no evidence of having NBCCS. This conclusion supports the findings from previous case series based on sporadic cases that OOC does not appear to be associated with NBCCS.

    Full Text Available Objective. The aim of this paper is to present an uncommon clinical and radiographic aspect of odontogenic keratocyst (OKC mimicking paradental cyst. Methods. A 32-year-old female patient showed a well-delimited radiolucent lesion connected with the root of the left third molar with close anatomical relationship with the mandibular canal. The clinical, radiographic, and anamnestic features lead us to diagnose a paradental cyst that was treated by enucleation after extraction of the partially impacted tooth. Results. Histological analysis showed typical histological features of PKC such as the presence of a lining of stratified squamous epithelium with a well-defined basal layer of palisading columnar of cuboidal cells. Conclusion. Initial X-ray analysis and the position of the lesion related to the third mandibular tooth caused us to mistakenly diagnose a paradental cyst. We were only able to identify the cyst as an PKC rather than a paradental cyst after histological analysis.

    Branchial cleft cysts occur because of a failure of involution of the second branchial cleft. However, as well-differentiated squamous cell carcinoma can mimic branchial cleft cysts, there is a lack of consensus on the appropriate management of cystic neck lumps. To report our experience of fine needle aspiration cytology and frozen section examination in the management of cystic neck lumps. Retrospective case note review of patients managed in the Southern General Hospital, Scotland, UK. The sensitivity of fine needle aspiration cytology and frozen section for detecting branchial cleft cysts was 75 per cent and 100 per cent respectively. Two patients who did not undergo intra-operative frozen section examination were either over- or under-treated, which is discussed. Adult patients subjected to surgical excision of a suspected branchial cyst should undergo intra-operative frozen section analysis regardless of clinical suspicion for malignancy. This part of management is critical to ensure patients are offered appropriate treatment.

    Full Text Available A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month. There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing, lens removal with intraocular lens implantation. Slit lamp examination revealed a corneal scar at 9’oclock, a large transilluminant iris cyst superotemporally and adherent to corneal endothelium. It was extended from angle of the pupil and obstructing the visual axis. The patient underwent excision of an iris cyst through superior limbal incision. Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma. Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule. Post operatively 7 days, vision improved to 6/7.5 without complication. There was no recurrence up to 1 year postoperation. Histopathological finding revealed a benign cyst mass lined by simple cuboidal to nonkeratinized stratified squamous epithelium. We had achieved a good surgical outcome with no complication to date for our case study. We advocate this modified surgical method to completely remove iris cyst.

    To evaluate the incidence and characteristic findings of pineal cyst incidentally detected on magnetic resonance (MR) imaging. Brain MR images obtained in 2432 patients were retrospectively reviewed to determine the incidence and MR findings of pineal cysts, which were evaluated according to their size, shape, location, signal intensity, interval change, contrast enhancement and mass effect on adjacent structures. Cysts were encountered in 107(4.4 %) of 2432 patients evaluated. their size ranged from 1 X 1 X 1 to 15 X 8 X 9 (mean, 5.97 X 3.82 X 4.82)mm. All were spherical (n=53) or oval (n=54) in shape. Their margin was smooth and they were homogeneous in nature. On T1-weighted images, the cysts were seen to be hyperintense (n=57) or isointense (n=50) to cerebrospinal fluid, but less so than brain parenchyma. T2-weighted images showed them to be isointense (n=51)or hyperintense (n=56) to cerebrospinal fluid. The cysts were centrally located in 65 cases and eccentrically in 42. Compression of the superior colliculi of the tectum was demonstrated in 17 cases (15.9 %). NO patients presented clinical symptoms or signs related to either pineal or tectal lesions. Peripheral enhancement around the cyst after Gd-DTPA injection was demonstrated in 51 cases(100 %). Follow-up examinations in 19 cases demonstrated no interval change. The incidence of pineal cysts was 4.4 %. The MR characteristics of simple pineal cysts include: (1) an oval or spherical shape, (2) a smooth outer margin and homogeneous nature, (3) isosignal or slightly high signal intensity to cerebrospinal fluid on whole pulse sequences, (4) ring enhancement after contrast injection, (5) an absence of interval change, as seen during follow up MR study. These MR appearances of pineal cysts might be helpful for differentiating them from pineal tumors

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23–37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T 1 , 16T 2 , 32T 3 and 22 T 4 . Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T 1 lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs

    Epidermoid cysts are benign, uncommon lesions (1% of all intracranial tumors). Their localization is intradiploic in 25% of cases, and exceptionally subtentorial. We report here a rare case of giant intradiploic infratentorial epidermoid cyst. A 74-year old patient presented with recent diplopia and sindrome cerebellar. CT scan and MR imaging revealed a giant osteolytic extradural lesion of the posterior fossa (5.2 cm x 3.8 cm) with a small area of peripheral enhancement after contrast injection. Retrosigmoid suboccipital craniectomy allowed a satisfactory removal of the tumor, followed by an acrylic cranioplasty. The outcome was good. Neuropathological examination confirmed an epidermoid cyst. We review the literature and discuss our case.

    Full Text Available Epidermoid cysts are benign slow growing more often extra-axial tumors that insinuate between brain structures, we present the clinical, imaging, and pathological findings in 35 years old female patients with atypical epidermoid cysts which was situated anterior, middle & posterior cranial fossa. NCCT head revealed hypodense lesion over right temporal and perisylvian region with extension in prepontine cistern with mass effect & midline shift and MRI findings revealed a non-enhancing heterogeneous signal intensity cystic lesion in right frontal & temporal region extending into prepontine cistern with restricted diffusion. Patient was detoriated in night of same day of admission, emergency Fronto-temporal craniotomy with anterior peterousectomy and subtotal resection was done. The histological examination confirms the epidermoid cyst. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

    SUMMARY Taxonomy: Superkingdom Eukaryota; kingdom Metazoa; phylum Nematoda; class Chromadorea; order Tylenchida; suborder Tylenchina; superfamily Tylenchoidea; family Heteroderidae; subfamily Heteroderinae; main genera Heterodera and Globodera. Cyst nematodes comprise approximately 100 known species in six genera. They are pathogens of temperate, subtropical and tropical plant species and the host range of many species is narrow. The most economically important species are within the Globodera and Heterodera genera. Globodera pallida and G. rostochiensis are important pathogens of potato crops. There are many economic species in the Heterodera genus, including Heterodera glycines (soybean cyst nematode), H. avenae (cereal cyst nematode) and H. schachtii (sugar beet cyst nematode), the last of which attacks a range of Chenopodiaceae and Cruciferae, including Arabidopsis thaliana. Disease symptoms: Field symptoms of severe cyst nematode infection are often stunting, wilting and chlorosis, but considerable yield loss can occur without obvious symptoms. The only unique indicator of cyst nematode infection is the presence of adult female nematodes attached to host roots after several weeks of parasitism. Disease control: This is usually achieved by using integrated pest management involving cultural practices such as crop rotation, resistant cultivars if available and chemical control when economically justified.

    To summarize the experience in diagnosis and treatment of congenital biliary duct cyst. Clinical data from 108 patients treated from 1980 to 2000 were analyzed retrospectively. Abdominal pain, jaundice and abdominal mass were presented in most pediatric patients. Clinical symptoms in adult patients were non-specific, resulting in delayed diagnosis frequently. Fifty-seven patients (52.7%) had coexistent pancreatic biliary disease. Carcinoma of the biliary duct occurred in 18 patients (16.6%). Ultrasonic examination was performed in 94 patients, ERCP in 46, and CT in 71. All of the patients were correctly diagnosed before operation. Abnormal pancreatobiliary duct junction was found in 39 patients. Before 1985, the diagnosis and classification of congenital biliary duct cyst were established by ultrasonography preoperatively and confirmed during operation. The main procedure was internal drainage by cyst-enterostomy. After 1985, the diagnosis was decided with ERCP and CT, the procedure was cyst excision with Roux-en-Y hepaticojejunostomy. In 1994, we used a new and simplified operative procedure to reduce the risk of malignancy of choledochal cyst. Retrograde infection of the biliary tract the major postoperative complication, could be controlled by the administration of antibiotics. The concept in diagnosis and treatment of congenital choledochal cyst has been changed greatly. CT and ERCP are of great help in the classification of the disease. Currently, cyst excision with Roux-en-Y hepaticojejunostomy is strongly recommended as the treatment of choice for patients with type I and IV cysts. Piggyback orthotopic liver transplantation is indicated for type V cysts (Caroli's disease) with frequently recurrent cholangitis, resulting in biliary cirrhosis.

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    Conclusion: A literature review revealed that this was a rare case of combined ABC–SCC associated with HPV 31 infection. In this case, the ABC component did not affect the tumor stage because it was confined to the cervix. However, we must avoid overestimating the clinical stage because the ABC component is thought to be a benign lesion.

    In the present study expression of cyclin D1 in the epithelial lining of odontogenic keratocyst, radicular cyst, dentigerous cyst and glandular odontogenic cyst was investigated to compare proliferative activity in these lesions. Immunohistochemical staining of cyclin D1 on formalin-fixed, paraffin-embedded tissue sections of odontogenic keratocysts (n=23), dentigerous cysts (n=20), radicular cysts (n=20) and glandular odontogenic cysts (n=5) was performed by standard EnVision method. Then, slides were studied to evaluate the following parameters in epithelial lining of cysts: expression, expression pattern, staining intensity and localization of expression. The data analysis showed statistically significant difference in cyclin D1 expression in studied groups (p keratocysts, but difference was not statistically significant among groups respectively (p=0.204, 0.469). Considering expression localization, cyclin D1 positive cells in odontogenic keratocysts and dentigerous cysts were frequently confined in parabasal layer, different from radicular cysts and glandular odontogenic cysts. The difference was statistically significant (p keratocyst and the entire cystic epithelium of glandular odontogenic cysts comparing to dentigerous cysts and radicular cysts, implying the possible role of G1-S cell cycle phase disturbances in the aggressiveness of odontogenic keratocyst and glandular odontogenic cyst.

    To discuss the experience of diagnosis and treatment of ovarian cyst in infants. A retrospective review was conducted on 20 infants who suffered from ovarian cyst. There were no dysplasia ovarian was found in children which were preoperatively diagnosed simplex cyst. Within thirteen children preoperatively detected mixed cystic-solid lesion, six cases ovarian cysts disappeared and two cases underwent poor blood supply in the following time. Adverse effects for ovarian cyst in infants can be prevented by agressive surgical intervention. Harmful effects of ovarian cyst can be prevented by positive surgical intervention despite the diagnostic difficulties in children with clinical symptoms of this condition.

    1984-06-01

    Anamnesis and treatment of two cases of arachnoid cysts extending into the subarachnoid space are described. No traumatic incident was discovered in the previous history of these two patients. The causal genesis of neurological signs of deficiency in patients with arachnoid and acquired cysts is discussed. However, the cause of the development of a subdural hygroma in arachnoid cysts remains unclarified. CT findings of arachnoid cysts with a hypodense zone between brain surface and the vault of the cranium always require an investigation into the possibility of a spontaneous emptying of the cyst or of a congenital and not only localised extension of the cyst itself.

    Full Text Available Nasopalatine duct cyst (NPDC is the most common non-odontogenic cyst of oral cavity. Clinically, Nasopalatine duct cyst manifests as an asymptomatic swelling of the palate or the upper lip. Radiographically, it is seen as a heart-shaped radiolucency and can be confused with periapical pathology. The aim of this article is to report a case of a nasopalatine duct cyst in a 36-year-old patient which was misinterpreted for a periapical cyst. Diagnosis of a Nasopalatine duct cyst can be given through clinical, radiographical, and histopathological examination.

    2008-12-01

    Full Text Available Abstract Background Squamous cells are normally not found inside the breast, so a primary squamous cell carcinoma of the breast is an exceptional phenomenon. There is a possible explanation for these findings. Case presentation A 72-year-old woman presented with a breast abnormality suspected for breast carcinoma. After the operation the pathological examination revealed a primary squamous cell carcinoma of the breast. Conclusion The presentation of squamous cell carcinoma could be similar to that of an adenocarcinoma. However, a squamous cell carcinoma of the breast could also develop from a complicated breast cyst or abscess. Therefore, pathological examination of these apparent benign abnormalities is mandatory.

    Full text: Introduction: We present a case of neuroendocrine tumor which is arisen from a tailgut cyst in a middle aged woman with its computed tomography (CT) imaging findings. Objective and tasks:The tailgut normally involutes by the eighth week of gestational age. If a tailgut rest proceeds, it may give rise to a tailgut cyst in the presacral space. Malign transformation of the tailgut cyst is very rare. Material and methods: A 35-year-old woman with a history of endometriosis admitted to our hospital for her routine control.An ultrasonography examination and contrast medium enhanced tomography of the abdomen and pelvis were performed. Results: CT showed multiple well-defined solid heterogen masses in presacral space. The patient underwent surgery. Pathology was reported as neuroendocrine tumor arising within tailgut cyst. Conclusion: Adenocarcinoma, neuroendocrine carcinoma, and sarcoma developing within the tailgut cyst has been reported. CT shows well-marginated presacral mass.If concurrent malignant transformation occurs, CT shows loss of margins and involvement of adjacent structures.Diagnosis of tailgut cyst is important because of it's malignant potential

    Cystic mesothelioma is a rare benign tumor of the abdominal and pelvic peritoneum, consisting of solitary or multiple cysts. No more than 130 cases are reported. Several risk factors such as chronic peritoneal irritation, caused by foreign bodies, infection or endometriosis, were hypothesized but the pathogenesis is still unknown. A 51-year menopausal woman was submitted to ultrasonography because of abnormal uterine bleeding. The scan revealed a right ovarian cyst (size 81 x 64 mm) with the feature of serous cyst. In the anamnesis a cystectomy of the right ovary and appendectomy were reported. At laparoscopy, then converted in laparotomy, a cyst arising from peritoneum of the posterior surface of the uterus was found. The right ovary was normal. The histopathological finding was: serous simple cyst of peritoneum. Ultrasonographic diagnosis was not confirmed by surgery; in fact, sometimes, it may be difficult to establish the origin of pelvic cystic mass, from ovary or peritoneum, by ultrasonography. It is mandatory to suggest a laparoscopy and/or laparotomy in case of pelvic cystic mass that does not regress in the time even after administration of oral contraceptives.

    A perspective study was carried out to assess the efficacy of a combination of percutaneous aspiration plus oral albendazole to assess its efficacy as an alternative to surgery in the treatment of hydatid cyst. We performed percutaneous aspiration followed by injection of 20% hypertonic saline solution into 16 hydatid cysts in 13 patients. All the patients received oral albendazole (400 mg/12 hours) starting 2 days before and lasting until there weeks after the procedure. There were no anaphylactic reactions during or after the procedure. Follow-up included monthly ultrasound over a period ranging between 10 and 36 months. Three cysts disappeared completely; in 10 cases, the cysts cavity was replaced by a complex ultrasonographic findings, with strong signals similar to those of a pseudotumor. In another case, the aspirate was sterile and its morphology remained unchanged. In two cases, infection of the cyst ensued, requiring surgical treatment. We consider that percutaneous aspiration in combination with albendazole may prove to be a good alternative to surgery for the management of hepatic hydatid disease. (Author) 15 refs

    Cystic duplications of the biliary tract are rare anomalies, easily mistaken for choledochal cysts. Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

    A 56-year-old man presented himself for an intracranial glioblastoma multiforme excision. After being routinely monitored, he was preoxygenated. We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation.

    Intraparenchymal or intradiploic epidermoid cysts are very rare. Most of these cysts, when present, tend to involve the frontal and temporal lobes, and occasionally, the pineal gland or the brain stem. Here, we report a 45-year-old female, who presented with localized occipital headache and a tender occipital swelling, gradually increasing in size. She was hemodynamically and neurologically stable and did not have any focal neurological deficits. Whole skull and brain imaging revealed a well-demarcated expansile lytic lesion in the right occipital bone, which was hypointense on T1-weighted and hyperintense on both T2-weighted imaging and diffusion-weighted imaging without any contrast enhancement. The patient underwent a right occipital craniotomy and total excision of the intradiploic space occupying lesion. Histopathological examination confirmed the lytic bone lesion over occipital bone as intradiploic epidermoid cyst.

    Full Text Available Arachnoid cysts are rare, usually benign, space-occupying central nervous system lesion. They are the results of an accumulation of cerebrospinal-like fluid between the cerebral meninges and diagnosed prenatally as a unilocular, simple, echolucent area within the fetal head. They may be primary (congenital (maldevelopment of the meninges or secondary (acquired (result of infection trauma, or hemorrhage. The primary ones typically dont communicate with the subarachnoid space whereas acquired forms usually communicate. In recent years, with the development of radiological techniques, the clinical detectability of arachnoid cysts seems to have increased.

    2017-03-01

    A 56-year-old G3P3 postmenopausal woman presented with a 5 month history of abnormal uterine bleeding and pelvic pain. A computed tomographic scan revealed a 5 cm right adnexal cystic mass in addition to a thickened, heterogenous endometrium and leiomyomatous uterus. A total laparascopic hysterectomy and bilateral salpingo-oophorectomy with omental and peritoneal biopsy were performed. Gross examination revealed a 12 week size uterus with small fibroids, normal bilateral atrophic ovaries, and a right paratubal cyst. A 4 cm vegetating mass was found in the right side of the uterine wall. Microscopically, the uterine mass was diagnosed as an endometrioid adenocarcinoma (EAC) FIGO 1 with 70% of myometrial invasion. The remaining endometrium showed a complex atypical hyperplasia. In addition, a 5 cm paratubal cystic mass was found that was separate from the uterus and the right adnexa. The cyst content was a chocolate brown fluid and the cyst wall was smooth with a single solid mass of 2 cm in size. The diagnosis of EAC, FIGO 1 was given. The remaining cyst lining showed endometriotic cyst and foci of endometriosis in the cyst wall. There was no lymphovascular invasion. The entire fallopian tube and ovaries were submitted and they were free of tumor. The patient was diagnosed with primary EAC of the paratubal cyst in addition to EAC of the uterine corpus (pT1b). A close follow-up was recommended. Because of our limited knowledge of carcinomas arising in the paratubal cyst, we will review the literature and discuss their clinical aspects, management, and behavior.

    For 10 case in which we detected cysts in the choledochus ourselves comparing traditional radiological methods (infusion-cholegram, ERC, scintigraphy, barium meal examination, angiography) with recent imaging procedures (ultrasound, CT, NMR) the following sequence of procedures proved to be favorable: Screening methods are ultrasound and infusion-cholegram. CT and NMR furnish good presentations of the intra- and extrahepatic dilatations of the bile duct. ERC still represents the best methods for demonstration of an extrahepatic cyst of the choledochus. Hepato-biliary functional scintigraphy is performed as a supplement. Barium meal examination and coeliacography furnish a small diagnostic contribution only. (orig.) [de

    2014-02-01

    Arthroscopy is an advancing field in orthopedics, the applications of which have been expanding over time. Traditionally, excision of ganglion cysts has been done in an open fashion. However, more recently, studies show outcomes following arthroscopic excision to be as good as open excision. Cosmetically, the incisions are smaller and heal faster following arthroscopy. In addition, there is the suggested benefit that patients will regain function and return to work faster following arthroscopic excision. More prospective studies comparing open and arthroscopic excision of ganglion cysts need to be done in order to delineate if there is a true functional benefit. Copyright © 2014 Elsevier Inc.

    Branchial cleft anomalies are a common cause of lateral neck masses and may present with infection, cyst enlargement or fistulas. They may affect any of the nearby neck structures, causing compressive symptoms or vessel thrombosis. We present a case of a branchial cleft cyst in a 10-year-old boy who had been present for 1year. At the time of operation, the cyst was found to completely envelop the hypoglossal nerve. While reports of hypoglossal nerve palsies due to external compression from cysts are known, we believe this to be the first report of direct nerve involvement by a branchial cleft cyst.

    Hematic cyst refers to accumulation of blood or blood breakdown products in a non epithelium-lined fibrous tissue capsule. Hepatic cyst is a term often used for deeply placed, incompletely resorbed hematoma hemorrhagic cyst, which may remain unchanged and unidentified for long periods of time. Trauma is the major causative factor, although it is often vague or totally uncalled by the patient. Chronic hematic cysts are uncommon lesions those can present diagnostic challenge. In this article we report a first case of a chronic hematic cyst of the temporomandibular joint TMJ. (author)

This study was carried out during 2005, where the cadavers were randomly included from the criminal laboratories of the Ministry of Justice, Republic of Turkey in Istanbul. None of the cadavers had laryngeal and cervical injuries resulting from a trauma or the cause of their death. The examined cadavers included 59 men and 21 females, and their ages were ranged from 35-80 years old. The larynges were removed and fixed in 10% formalin and then dissected. The sections were examined using surgical SMZ 10 Nikon stereomicroscope. We evaluated the presence, localization and diameter of the cysts with regard to age and sex of the cadavers. We observed a total of 12 different localization of thyroglossal ducts and cysts among the 80 dissected cadavers. Ten of these ducts cysts were found in males with an age range of 35-68 years and 2 female cadavers aged 45-65 years. In 6 cases, the thyroglossal ducts and cysts were located in the left of the midline of the neck, while 3 cases were from the right of the midline, and the remaining was located on the midline of the neck. In all cases, thryoglossal ducts and cysts were complete and restricted to the infrahyoid region: all of them had connection with the hyoid bone, but not with the perichondrium of the cartilage. In addition, the thyroglossal ducts have connection with the left lobe of the thyroid glands in 3 cases, one case in the right lobe, and 2 cases with the isthmus of the thyroid gland. Finally in 5 cases thyroglossal ducts were complete and had well developed cysts. Thyroglossal duct remnants are one of the most often seen congenital asymptomatic masses of the neck region (7%). The presence of these duct remnants may lead to abnormal phonation and epithelial carcinomas. Therefore, correlation of

    Full Text Available bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery.

    Is is shown that ultrasonography, computer tomography, laparoscopy provide for liver cyst detection. Parasitic cyst of Echinococcus and opisthhordeiasis nature are subject to surgical treatment. Selective procedures under echinococcosis include echinococcotomy and liver resection, and under opisthorchiasis - liver resection. Under nonparasitic liver cysts of minor size dynamic observation is advisable, under medium, hard and multiple complication cysts - sergical treatment is advisable. Selective procedures under non-complicated cysts include cyst resection with tamponage using omentum, and under complicated multiple cysts - liver resection

    Reinke edema is one of the common cause of dysphonia middle-aged population, and severe thickening of vocal folds require surgical treatment. Smoking plays a major role on etiology. Vocal fold cysts are also benign lesions and vocal trauma blamed for acquired cysts. We would like to present 3 cases with vocal fold cyst related with Reinke edema. First case had a subepidermal epidermoid cyst with Reinke edema, which could be easily observed before surgery during laryngostroboscopy. Second case had a mucous retention cyst into the edematous Reinke tissue, which was detected during surgical intervention, and third case had a epidermoid cyst that occurred 2 months after before microlaryngeal operation regarding Reinke edema reduction. These 3 cases revealed that surgical management of Reinke edema needs a careful dissection and close follow-up after surgery for presence of vocal fold cysts.

    Many Chrysophyte algae produce morphologically distinctive, siliceous, microscopic cysts during a resting stage of their life cycles; these cysts are often preserved in sediments. Scanning electron microscopy and Nomarski optics permit much more detailed observation of these cysts than was heretofore possible. We have used an ecologic and biogeographic approach to study the distribution of cyst forms in sediments and have established that many cyst types are found only in specific habitats, such as montane lakes, wet meadows, ephemeral ponds, and Sphagnum bogs. In the samples we have studied, cysts seem to be most common in fluctuating fresh-water habitats of low to moderate pH and some winter freezing. Numerous taxonomic problems have yet to be resolved. We believe that chrysophyte cysts have the potential to become a useful tool for both modern environmental assessments and paleoecological studies of Cenozoic fresh-water lacustrine deposits.

    The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone) or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula) managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts.

    Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%).

    Sclerotherapy for renal cysts was performed, using 50% acetic acid as new sclerosing agent. We report the methods and results of this procedure. Fifteen patients underwent sclerotherapy for renal cyst, using 50% acetic acid. Because four patients were lost to follow-up, only 11 of the 15 were included in this study. The renal cysts, including one infected case, were diagnosed by ultrasonograpy (n=3D10) ormagnetic resonance imaging (n=3D1). The patient group consisted of four men and seven women(mean age, 59 years; range, 23-77). At first, the cyst was completely aspirated, and 25 volume% of aspirated volume was replaced with 50% sterile acetic acid through the drainage catheter. During the follwing 20 minutes, the patient changed position, and the acetic acid was then removed from the cyst. Finally, the drainage catheter was removed, after cleaning the cyst with saline. After treatment of infection by antibiotics and catheter drainage for 7 days, sclerotherapy in the infected case followed the same procedure. In order to observe changes in the size of renal cysts and recurrence, all patients were followed up by ultrasound between 2 and 8 months. We defined response to therapy as follows:complete regression as under 5 volume%, partial regression as 5-50 volume% and no response as more than 50 volume% of initial cyst volume. No clinically significant complication occured during the procedures or follow-up periods. All cysts regressed completely during follow-up of 8 months. Complete regression occurred as follows: two cysts at 2 months, seven cysts at 4 months, two cysts at 6 months. Two cysts showed residues at the last follow-up, at 4 and 6 months, respectively. The volume of residual cysts decreased to under 5 volume% of initial volume, however. Completely regressed cysts did not recurr during follow-up. Acetic acid sclerotherapy for renal cysts showed good results, regardless of the dilution of sclerosing agent with residual cyst fluid, and no significant

    An epidermoid cyst is a benign cyst usually found on the skin. Bone cysts are very rare and if they appear in bone they usually appear in the distal phalanges of the fingers. Epidermoid cysts of the jaws are uncommon. We present a case, of a 41 year-old female patient admitted to our department because of pain and swelling in the parotid and masseteric region-left side. There was no trismus, pathological findings in skin, high body temperature level, infra-alveolar nerves anesthesia or lymphadenopathy present. The orthopantomography revealed a cystic lesion and a unilocular lesion that included mandibular ramus on the left side with 3 cm in diameter. Under total anesthesia, a cyst had been reached and was enucleated. Histopathologic findings showed that the pathologic lesion was an epidermoid cyst. Epidermoid and dermoid cysts are rare, benign lesions found throughout the body. Only a few cases in literature describe an intraossesus epidermoid cyst. Our case is an epidermoid cyst with a rare location in the region of the mandibular ramus. It is not associated with any trauma in this region except medical history reveals there was an operative removal of a wisdom tooth 12 years ago in the same side. These cysts are interesting from the etiological point of view. They should be considered in the differential diagnosis of other radiolucent lesions of the jaws. Surgically they have a very good prognosis, and are non-aggressive lesions.

    Apical periodontitis can appear clinically as apical granulomas or radicular cysts. There is evidence that immunologic factors are involved in the pathogenesis of both pathologies. In contrast to radicular cysts, the dentigerous cysts have a developmental origin. Macrophage polarization (M1 vs M2) is a main regulator of tissue homeostasis and differentiation. There are no studies comparing macrophage polarization in apical granulomas, radicular cysts, and dentigerous cysts. Forty-one apical granulomas, 23 radicular cysts, and 23 dentigerous cysts were analyzed in this study. A tissue microarray (TMA) of the 87 consecutive specimens was created, and CD68-, CD11c-, CD163-, and MRC1-positive macrophages were detected by immunohistochemical methods. TMAs were digitized, and the expression of macrophage markers was quantitatively assessed. Radicular cysts are characterized by M1 polarization of macrophages while apical granulomas show a significantly higher degree of M2 polarization. Dentigerous cysts have a significantly lower M1 polarization than both analyzed periapical lesions (apical granulomas and radicular cysts) and accordingly, a significantly higher M2 polarization than radicular cysts. Macrophage cell density in dentigerous cysts is significantly lower than in the periapical lesions. The development of apical periodontitis towards apical granulomas or radicular cysts might be directed by macrophage polarization. Radicular cyst formation is associated with an increased M1 polarization of infiltrating macrophages. In contrast to radicular cysts, dentigerous cysts are characterized by a low macrophage infiltration and a high degree of M2 polarization, possibly reflecting their developmental rather than inflammatory origin. As M1 polarization of macrophages is triggered by bacterial antigens, these results underline the need for sufficient bacterial clearance during endodontic treatment to prevent a possible M1 macrophage-derived stimulus for radicular cyst

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    To summarize the experience of diagnosis and treatment of congenital choledochal cyst in the past 20 years (1980-2000). The clinical data of 108 patients admitted from 1980 to 2000 were analyzed retrospectively. Abdominal pain,jaundice and abdominal mass were presented in most child cases. Clinical symptoms in adult cases were non-specific, resulting in delayed diagnosis frequently. Fifty-seven patients (52.7%) had coexistent pancreatiobiliary disease. Carcinoma of the biliary duct occurred in 18 patients (16.6%). Ultrasonic examination was undertaken in 94 cases, ERCP performed in 46 cases and CT in 71 cases. All of the cases were correctly diagnosed before operation. Abnormal pancreatobiliary duct junction was found in 39 patients. Before 1985 the diagnosis and classification of congenital choledochal cyst were established by ultrasonography preoperatively and confirmed during operation, the main procedures were internal drainage by cyst enterostomy. After 1985, the diagnosis was established by ERCP and CT, and cystectomy with Roux-en-Y hepaticojejunostomy was the conventional procedures.In 1994, we reported a new and simplified operative procedure in order to reduce the risk of choledochal cyst malignancy. Postoperative complication was mainly retrograde infection of biliary tract, which could be controlled by the administration of antibiotics, there was no perioperative mortality. The concept in diagnosis and treatment of congenital choledochal cyst has obviously been changed greatly.CT and ERCP were of great help in the classification of the disease.Currently, cystectomy with Roux-en-Y hepaticojejunostomy is strongly recommended as the choice for patients with type I and type IV cysts. Piggyback orthotopic liver transplantation is indicated in type V cysts (Caroli's disease) with frequently recurrent cholangitis.

    Thirty-one patients with malignant tumors of the middle ear and external auditory canal (EAC) were observed at the University of Virginia Hospital from 1956 through 1980. Of 27 patients with carcinoma, 21 had squamous cell carcinoma, 4 had basal cell carcinoma and 2 had adenoid cystic carcinoma. The 27 patients with carcinoma are reviewed with regard to clinical presentation, treatment modality, results and complications. The majority (67%) of patients had a history of chronic ear drainage, 22% had a previous mastoidectomy or polypectomy and 7% had an associated cholesteatoma. Eighty percent of patients with carcinoma limited to EAC were alive and well at 5 years, compared to 43% of patients with involvement of the middle ear. Fifty-six percent of patients without invasion of the petrous bone were alive at 5 years compared to only 20% of patients with petrous bone involvement. The data strongly suggest that survival depends on the extent of disease. The corrected disease free 5 year survival rates were 14% for patients who had surgery alone and 50% for those who had surgery and radiotherapy. Of the three patients with advanced disease who received radiotherapy alone, none survived five years

On CT scan, it showed a well-organized peripheral calcification resembling a myositis ossificans. On MRI, it presented as a multilocular, cystic lesion with fluid-fluid levels. The lesion had no solid components except for intralesional septa. Although findings on imaging and histology were identical to those described in classical aneurysmal bone cyst, diagnosis was delayed because of lack of knowledge of this entity and its resemblance to the more familiar post-traumatic heterotopic ossification (myositis ossificans).

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    Full Text Available Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland and the oral cavity (usually the floor of the mouth. there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography.It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management.

    Full Text Available Orthokeratinized Odontogenic Cyst (OOC is a developmental cyst of odontogenic origin and was initially defined as the uncommon orthokeratinized variant of the Odontogenic Keratocyst (OKC, until the World Health Organization′s (WHO′s classification in 2005, where it was separated from the Keratocystic Odontogenic Tumor (KCOT. It is a relatively uncommon developmental cyst comprising of only 0.4% of all odontogenic cysts. It is rather mystifying that its radiographic features are similar to the dentigerous cyst and histological characteristics are similar to the odontogenic keratocyst; and it has inconsistent cytokeratin expression profiles overlapping with both the dentigerous cyst and odontogenic keratocyst as well as with the epidermis. It has a predilection for the posterior mandibular region. This is a report of a rare case of OOC in an unusual maxillary anterior region, with emphasis on its biological characteristics.

    Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

    CT is indispensable in the evaluation of renal masses, providing noninvasive and clear transverse images. With wider clinical application of CT, renal cysts have been found more frequently. CT examinations on 500 patients, who underwent CT for the diagnosis of renal diseases except for renal cysts, have been reviewed and analysed. The incidence of renal cysts was 9.6 % without prediction for sexes, but the incidence and sizes of the cysts increased with the advancing age. The upper portion of the kidneys was more frequently involved, but there was no relationship between number, sex and age of the patients. Since renal cysts produce mass effect in the kidneys, understanding of the nature and incidence of the renal cysts is important in diagnosing renal mass lesions. (author)

    Radicular cysts are inflammatory odontogenic cysts of tooth bearing areas of the jaws. Most of these lesions involve the apex of offending tooth and appear as well-defined radiolucencies. Owing to its clinical characteristics similar to other more commonly occurring lesions in the oral cavity, differential diagnosis should include dentigerous cyst, ameloblastoma, odontogenic keratocyst, periapical cementoma and Pindborg tumour. The present case report documents a massive radicular cyst crossing the midline of the palate. Based on clinical, radiographical and histopathological findings, the present case was diagnosed as an infected radicular cyst. The clinical characteristics of this cyst could be considered as an interesting and unusual due to its giant nature. The lesion was surgically enucleated along with the extraction of the associated tooth; preservation of all other teeth and vital structures, without any postoperative complications and satisfactory healing, was achieved.

    On the basis of the studies listed in the bibliography, this dissertation reports on the pathology, clinical symptoms and radiology of cysts of the semilunar cartilage. The author analyses 118 cases of his own, with special regard to the results of pneumo-arthrographic investigations carried through according to a special technique by Schaefer. In the course of this work, measurements of the meniscal base are for the first time used as radiological criteria indicating the presence of a cyst of the semilunar cartilage. Furthermore the well-known radiological signs of cysts, such as bone defects according to Albert and Keller, light central spot in the meniscal body, as well as Rauber's sign and horizontal rupture, are investigated as to the frequency of their incidence. For that purpose all the X-ray pictures were subjected to a further dose scrutiny. A list of all the 118 cases with their clinical and radiological data is found in the annex, together with the results of the operations and patho-anatomical investigations. (orig.) [de

    The objective was to document the hydatid cyst cases in the endemic Cukurova region of Turkey, by their involvement sites in the body, and discuss the clinical and morphological features of the cases with rare localization. Archival materials of 153 hydatid cyst cases that were diagnosed in 2 different medical centers in Adana, Turkey Cukurova region between the years 2000-2006 were included in the study. Cases with rare localizations were re-evaluated in terms of clinical and laboratory findings, and histopathological features. Involvement sites of the cases were documented, cases with rare localizations are discussed. The liver was the most common localization with 63 cases followed by lungs with 54 cases. Uncommon locations were spleen n=4, bone n=3, intra-arterial n=1, ovary n=1, adrenal n=1, heart n=1, mesenteric n=2, retroperitoneal n=2, subcutaneous tissue n=4, breast n=1, intramuscular tissue n=4. The diagnosis of hydatic cyst should be considered in patients with a cystic mass, who live or have lived in a geographic region that has a high risk for Echinococcus granulosus, or visited an endemic area.

    Full Text Available Cystic lesions of the mediastinum may be congenital or acquired. The differential diagnosis depends on their location in the mediastinum. Cysts in the posterior mediastinum are generally developmental cysts and are neurogenic or of foregut origin. We report the case of a 14-year-old boy, who presented with dry cough and progressively increasing breathlessness, and was found to have a cystic lesion in the posterior mediastinum. Fine needle aspiration from the cyst helped make a diagnosis of tuberculosis.

    1999-03-01

    Unicameral bone cysts are not seen commonly in the calcaneus. Little is known about the etiology and natural history of these lesions. Calcaneal cysts often are symptomatic, although some of these lesions are detected as incidental findings. Treatment has been advocated based on the fear of pathologic fracture and collapse. Several published series have been divided in their favor for either open treatment or injection management. These series are small, and the optimal treatment is still in question. The current study compared the efficacy of methylprednisolone acetate injection treatment with curettage and bone grafting in the treatment of unicameral bone cysts of the calcaneus. All patients treated for unicameral bone cysts of the calcaneus during the past 7 years at two institutions were reviewed. Eleven patients met inclusion criteria. All diagnoses were confirmed radiographically or histologically. Demographic information, presenting complaints, diagnostic imaging, treatment modalities, and outcome were analyzed. Long term radiographic and subjective followup was obtained. Eighteen surgical procedures were performed on 11 patients with 12 cysts. Nine injections performed on six patients failed to show healing of the cyst. Nine cysts treated with curettage and bone grafting showed cyst healing. At mean followup of 28 months (range, 12-77 months), all 11 patients had no symptoms; there were no recurrences of the cyst in the nine patients who underwent bone grafting and persistence of the cyst in the two patients who underwent injection therapy. This review reports one of the largest series of cysts in this location. The results indicate that steroid injection treatment, although useful in other locations, may not be the best option for the management of unicameral bone cysts in the calcaneus. Curettage and bone grafting yielded uniformly good results.

    Among the pseudocysts of the jaws, the traumatic bone cyst is known as an asymptomatic lesion often noted unintentionally during routine radiographic examinations. The lesion neither devitalizes the teeth within its borders, nor does it cause resorption of their roots. The well-demarcated traumatic bone cyst often projects into the intraradicular septa and hence has been described as having scalloped borders. The following presentation is of a traumatic bone cyst that resembled periodontal pathology in its appearance.

    Background: The aim of the paper was the US evaluation of hormonal disorders and treatment results in adolescent girls and boys with breast cysts. Material/Methods: In the years 2001 - 2009, US examination of the breast was performed in 427 children aged 10 - 18 years, with clinically suspected breast pathologies. The indications for US examination typically included pain, breast swelling and a palpable tumor. The US examination was performed using a 7 - 12 MHz linear transducer. Results: Breast cysts were found in 42 children: 36 adolescent girls and 6 boys with gynaecomastia. Infected cysts were found in 35 children. The cysts ranged in size from 5 mm to 30 mm. In 5 of the girls, large cysts were treated by an incision and drainage, and in all the children with infected cysts, antibiotic therapy was used. Hormonal disorders were found in 30 girls. A follow-up examination was performed, and the observation time varied from 1/12 to 2 years. The cysts disappeared completely in 30 children. Hormonal therapy was introduced in 5 girls. Conclusions: Breast cysts found in US examinations are indications for check-up examinations including endocrinological diagnostics and, if the cyst is persistent, possibly for hormonal treatment.

    The so-called "globulomaxillary cyst", described as a fissural cyst, caused by entrapped epithelium between the nasal and maxillary process, is no longer considered for its own entity. Nevertheless, cystic lesions, which correspond to the previous image of globulomaxillary cysts, do still occur in daily practice. This raises the question to which entities pathological processes in this particular region actually belong to. In a retrospective study, 17 cases (12 men and 5 women, 12-59 years old) of primarily diagnosed globulomaxillary cysts are analysed according to clinical, radiological and histological aspects, catamnestic processed and assigned to a new entity. The results are compared with the international literature and draws conclusions on the diagnostic and therapeutic procedure. Seven lateral periodontal cysts, four radicular cysts, two keratocystic odontogenic tumours, one adenomatoid odontogenic tumour, one periapical granuloma, one residual cyst and one undefined jaw cyst were determined. According to the results of our study and the data from the international literature, the entity globulomaxillary cyst is no longer justified.

    Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

    To compare the long-term outcomes in patients with salivary gland adenoid cystic carcinoma (SGACC) treated with post-operative chemoradiotherapy (POCRT) versus post-operative radiotherapy (PORT). We retrospectively reviewed the records of 91 SGACC patients treated with surgery followed by PORT (n = 58) or POCRT (n = 33) between 2000 and 2013. Treatment outcomes between groups were compared using propensity score matching (1:1 nearest neighbor). The median radiation dose was 66 Gy, and patients were followed up for a median of 71 months. Cisplatin-based concurrent regimens were the most commonly used chemotherapy schedules. In the entire study cohort, patients undergoing POCRT showed a trend toward higher locoregional control (LRC) rates than those treated with PORT alone at both 5 and 8 years (97 and 97 % versus 84 and 79 %, respectively; P = .066). Distant metastases were the most common form of treatment failure and occurred in 31 (34 %) patients (PORT, n = 17; POCRT, n = 14). After propensity score matching (33 pairs), patients receiving POCRT had 5- and 8 year LRC rates of 97 and 97 %, respectively, compared with 79 and 67 % for patients treated with PORT alone (P = .017). The two groups did not differ significantly in terms of distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS). However, a significantly better opioid-requiring pain-free survival (ORPFS) was achieved in POCRT group (P = .038). Subgroup analyses revealed that patients with stage III − IV disease (P = .040 and .017), positive surgical margins (P = .011 and .050), or perineural invasion (P = .013 and .035) had significantly higher 5- and 8 year LRC and ORPFS when treated with POCRT, respectively. In SGACC patients, adding concurrent chemotherapy to PORT may increase LRC and ORPFS rates, particularly in presence of stage III − IV disease, positive surgical margins, or perineural invasion. However, no significant differences in DMFS, DFS, and OS were

    Full Text Available The enlarged adenoid serves as a mechanical obstacle on the nasopharynx to intricate nasotracheal intubation. No matter what video or direct laryngoscopic techniques are applied, nasotracheal tube navigation from the nasal valve area through the nasal cavity to the nasopharynx is always blind; trauma is not uncommon. Here we report a case of unintended avulsed adenoids that plugged the tube tip while the nasotracheal tube blindly navigated through the nasopharyngeal space. After failing to insert a bent tip of gum elastic bougie passing through the nasopharynx, an alternative method of NTI was performed by mounting the nasotracheal tube on a fiberoptic bronchoscope. The nasotracheal tube was successfully railroaded along the insertion tube of the fiberscope to the trachea.

    In a 86-year-old woman, basal cell carcinoma (BCC) arose on the skin with chronic radiation dermatitis. She, at the age of 46, received irradiation to the abdomen for cancer of the uterine cervix. Radiation source and dose were unknown. A verrucous eruption appeared on the irradiated field of the right abdomen, and gradually expanded. Histological examination showed that proliferation of tumor cells with adenoid and cystose structure extended to the epidermis. Electron microscopic study showed both clear and dark tumor cells, although dark cells were few in number. A review of the literature showed that BCC arising on the skin with chronic radiation dermatitis is uncommon in Japan. (Namekawa, K.)

    Odontogenic cysts, which showed cystic radiolucency in the jaw bone by radiographic examination and computed tomography, were enucleated by operation in 3 dogs. One dog had a odontogenic keratocyst in the incisive bone of the right maxilla and another 2 cases revealed dentigerous cysts in the mandible. These cyst walls were enucleated or transpired by semiconductor laser. Afterwards, osteogenesis was confirmed at the defective part of jaw bone by extirpation of the cyst in all cases, and no recurrence has been noted in any cases. Odontogenic cyst is a disease which should be treated by surgical extirpation or transpiration.

    2009-05-01

    It is a general belief that large cyst-like periapical lesions and apical true cysts caused by root canal infection are less likely to heal after nonsurgical root canal therapy. Nevertheless, there is no direct evidence to support this assumption. A large cyst-like periapical lesion or an apical true cyst is formed within an area of apical periodontitis and cannot form by itself. Therefore, both large cyst-like periapical lesions and apical true cysts are of inflammatory and not of neoplastic origin. Apical periodontitis lesions, regardless of whether they are granulomas, abscesses, or cysts, fail to heal after nonsurgical root canal therapy for the same reason, intraradicular and/or extraradicular infection. If the microbial etiology of large cyst-like periapical lesions and inflammatory apical true cysts in the root canal is removed by nonsurgical root canal therapy, the lesions might regress by the mechanism of apoptosis in a manner similar to the resolution of inflammatory apical pocket cysts. To achieve satisfactory periapical wound healing, surgical removal of an apical true cyst must include elimination of root canal infection.

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Parathyroid cyst is an infrequent and unsuspected disease. There are more than 300 hundred cases reported in the world literature, a few of them are from Latin America. The experience of our centers and a review of the cases are presented. Case report of a series of patients with parathyroid cyst from our institutions according to the CARE guidelines (Case Reports). A search of Medline, Embase, BIREME ( Biblioteca Regional de Medicina ) LILACS ( Literatura Latinoamericana y del Caribe en Ciencias de la Salud ), Google Scholar and Scielo ( Scientific Electronic Library on Line ) databases and telephonic or email communications with other experts from Latin-America was performed . Six patients with parathyroid cyst were found in our centers in Colombia. Most of them were managed with aspiration of the cyst. Two of them required surgery. Only one case was functional. Twelve reports from Latin America were found for a total of 18 cases in our region adding ours. Parathyroid cysts are uncommonly reported in Latin America. Most of them are diagnosed postoperatively. Suspicion for parathyroid cyst should be raised when a crystal clear fluid is aspirated from a cyst. The confirmation of the diagnosis may be easily done if parathyroid hormone (PTH) level is measured in the cyst fluid.

    Aneurysmal bone cyst is a benign proliferative tumefaction of bone. Histologic similarities indicate a kinship among classic aneurysmal bone cysts, essentially 'solid' proliferative lesions in bones; giant cell reparative granulomas of the jaws, at the base of the skull, and in the small bones of the hands and feet; skeletal lesions of hyperparathyroidism; and even pseudosarcomatous myositis ossificans, proliferative myositis, and proliferative fasciitis.

    Omental and mesenteric cysts are uncommon diseases mostly occurring in young children. They are felt to have a common origin from obstructed or ectopic lymphatics. We reviewed three cases of omental cyst and three cases of mesenteric cyst. Sonography showed cystic mass with a thin wall and multiple thin septi dividing the cyst into multiple irregular spaces. In most cases(5/6) solid portions were detected and they were proved to be tissue debris and hemorrhagic clots. Fluid content was either anechoic or echogenic. Floating echogenicities or fluid-fluid level were detected in some cases. Ultrasound is very useful in the diagnosis of omental and mesenteric cysts in children, giving reliable information relating to internal hemorrhage, infection or adhesion to adjacent organs

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    Full Text Available Background. A six-year-old boy presented with a large progressive intracorneal and scleral cyst. Two years before, bilateral cataract surgery through a 6.5-mm corneal incision was performed elsewhere.Methods. The posterior wall of the cyst could be excised, as well as the anterior wall in the sclera. Upon histo-pathology the cyst wall was lined by epithelium. The epithelial cells of the anterior side in the cornea were removed with a curette and a corpus alienum drill. Three and a half years after removal of the cyst, there was no recurrence. Visual acuity was 0.8. Conclusions. An intracorneal and scleral inclusion cyst was successfully removed by surgical excision and the removal of epithelial cells by a curette and a corpus alienum drill.

    Oral foregut cysts are congenital choristomas that arise in the oral cavity during embryonic development from remnants of foregut-derived epithelium. This is an unusual report of a neonate with a large congenital sublingual cystic lesion, extending superficially from the left ventral tongue to the anterior floor of the mouth, impeding breast-feeding. The differential diagnosis included dermoid cyst, epidermoid cyst, mucous retention cyst, and oral lymphangioma. The treatment of choice was enucleation under general anesthesia. Histology showed a cystic lesion with a ciliated pseudostratified columnar epithelium with numerous goblet cells. Immunohistochemistry was positive for cytokeratin 7 and thyroid transcription factor 1 and negative for cytokeratin 20, resulting in a final diagnosis of an oral foregut cyst. Three weeks after surgery, the tongue had healed with good mobility, and breast-feeding could be established. No recurrence was present at 6 months of follow-up.

    Hydatid cysts in the neck are relatively exceptional, even in areas where Echinococcus granulosis is endemic, such as Asia. Although liver and lung are frequent sites of involvement, it can involve all tissues, with neck remaining one of the most rare sites. It should come in the differential diagnosis of cystic lesion of neck, as the treatment options differ widely from common neck cysts. The role of radiological investigation is important and, in these cases, the involvement of other organs should be investigated. Serological tests may be helpful. The major treatment modality is surgical and the cyst should be excised as a whole, without being ruptured, to prevent any treatment complications, as the cyst fluid can initiate an anaphylactic reaction. Postoperative albendazole therapy is recommended particularly when there is intra-operative spillover. We report a case of an isolated hydatid cyst localized in the anterior triangle of the neck without any pulmonary or hepatic involvement. (author)

    Full Text Available Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

    The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts. Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped lobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7 cm in diameter (mean, 2.6 cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU (mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases (93%), and heterogeneously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts (14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles

    Full Text Available Background: As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH. Patients and Methods: A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients′ data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Results: Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1 belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years. The age group of 3-5 years had the highest (n = 40, 40% number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85% surgery performed on patients who had obstructive sleep apnea (OSA. The commonest (n = 6, 6% complication was haemorrhage, and only few (n = 3, 3% patients had blood transfusion. However, mortality was recorded in some (n = 3, 3% patients. Conclusion: This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    The pediatric dental approach to the oral cavity of newborns requires special attention, as many aspects are unique and peculiar to this period of life. It is important that pediatricians and pediatric dentists be aware of the characteristics within normal newborn patterns and prepared to make a correct diagnosis of abnormalities at early stages. Congenital eruption cysts (ECs) are rarely observed in newborns, as at this stage of a child's life, tooth eruption is unusual. This study reports a case of EC treated successfully by monitoring of the lesion, without any surgical procedure. In the 4th month, the lesion had completely regressed, and the deciduous central incisors had erupted without problems. The clinical and radiographic monitoring of ECs in newborns seems to be a satisfactory management procedure, similar to what is recommended for older children.

    Odontogenic cysts are the most common cysts of the jaws and are formed from the remnants of the odontogenic apparatus. Among these odontogenic cysts, radicular cysts (RCs) (about 60% of all diagnosed jaw cysts), dentigerous cysts (DCs) (16.6% of all jaw cysts) and odontogenic keratocysts (OKCs) (11.2% of all developmental odontogenic cysts) are the most common. The behavior of any lesion is generally reflected by its growth potential. Growth potential is determined by measuring the cell proliferative activity. The cell proliferative activity is measured by various methods among which immunohistochemistry (IHC) is the commonly used technique. Most of the IHC studies on cell proliferation have been based on antibodies such as Ki-67 and proliferating cell nuclear antigen. In the present study, the total sample size comprised of 45 cases of odontogenic cysts, with 15 cases each of OKC, RC and DC. Here, an attempt is made to study immunohistochemical (streptavidin-biotin detection system HRP-DAB) method to assess the expression of Ki-67 in different layers of the epithelial lining of OKCs, RCs and DCs. Ki-67 positive cells were highest in epithelium of OKC as compared to DC and RC. The increased Ki-67 labeling index and its expression in suprabasal cell layers of epithelial lining in OKC and its correlation with suprabasal cell layers of epithelial lining in DC and RC could contribute toward its clinically aggressive behavior. OKC is of more significance to the oral pathologist and oral surgeon because of its specific histopathological features, high recurrence rate and aggressive behavior.

    Full Text Available The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts.

    To report the effectiveness of Minocin sclerotherapy in the treatment of renal cysts. We performed minocin sclerotherapy to 19 patients with 21 renal cysts composed of 17 cases of solitary renal cyst and three cases of multiple renal cyst and one case of polycystic kidney confirmed by ultrasound and CT. After aspiration of cyst fluid, if the amount was less than 50 ml, 500 mg of minocin was mixed with 3 ml of normal saline, if more than 50 ml, 1000 mg of minocin mixed with 5 ml of normal saline were injected, and each case was followed-up over 3 months by ultrasound. Of all 21 renal cysts, 14 cases were followed-up three months after minocin sclerotherapy. In 12 of 14 case, the size of the cysts decreased by 10% or collapsed completely. Of the remaining two cases, one collapsed after 6 months while the other recurred after 6 months. Three cases were followed up after 20 months and only one of them recurred. 19 of all 21 cases(91%) were cured, and two of 21 cases(9%) were recurred. Pain was the only complaint and four of 10 cases needed analgesics. Sclerotherapy with minocin has low recurrence-rate and low complication, and relatively early high cure-rate.

The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

    Vocal cysts are benign laryngeal lesions, which affect children and adults. They can be classified as epidermic or mucous-retention cyst. The objective was to study the clinical, endoscopic, and surgical aspects of vocal cysts. We reviewed the medical charts of 72 patients with vocal cysts, considering age, gender, occupation, time of vocal symptoms, nasosinusal and gastroesophageal symptoms, vocal abuse, tabagism, alcoholism, associated lesions, treatment, and histological details. Of the 72 cases, 46 were adults (36 females and 10 male) and 26 were children (eight girls and 18 boys). As far as occupation is concerned, there was a higher incidence of students and teachers. All the patients had symptoms of chronic hoarseness. Nasosinusal (27.77%) and gastroesophageal (32%) symptoms were not relevant. Vocal abuse was reported by 45.83%, smoking by 18%, and alcoholism by 8.4% of the patients. Unilateral cysts were seen in 93% of the cases, 22 patients had associated lesions, such as bridge, sulcus vocalis, and microweb. Surgical treatment was performed in 46 cases. Histological analysis of the epidermic cysts revealed a cavity with caseous content, covered by stratified squamous epithelium, often keratinized. Mucous cysts presented mucous content, and the walls were coated by a cylindrical ciliated epithelium. Vocal cysts are benign vocal fold lesions that affect children and adults, being often associated with vocal overuse, which frequently affects people who use their voices professionally. Vocal symptoms are chronic in course, often times since childhood, and the treatment of choice is surgical removal. A careful examination of the vocal folds is necessary during surgery, because other laryngeal lesions may be associated with vocal cysts. Copyright © 2011 The Voice Foundation.

    To review management strategies for treatment of anterior chamber epithelial cysts. Retrospective review of consecutive interventional case series. Charts of patients treated for epithelial ingrowth over a 10-year period by a single surgeon were reviewed. Cases of anterior chamber epithelial cysts were identified and recorded, including details of ocular history, preoperative and postoperative acuity, intraocular pressure (IOP), and ocular examination, type of surgical intervention, and details of further procedures performed. Seven eyes with epithelial cysts were identified. Patient age ranged from 1.5 to 53 years at presentation. Four patients were children. In four eyes, cysts were secondary to trauma, one case was presumably congenital, one case developed after corneal perforation in an eye with Terrien's marginal degeneration, and one case developed after penetrating keratoplasty (PK). Three eyes were treated with vitrectomy, en bloc resection of the cyst and associated tissue, fluid-air exchange and cryotherapy. The last four eyes were treated with a new conservative strategy of cyst aspiration (three cases) or local excision (one keratin "pearl" cyst), and endolaser photocoagulation of the collapsed cyst wall/base. All epithelial tissue was successfully eradicated by clinical criteria; one case required repeat excision (follow-up, 9 to 78 months, mean 45). Two eyes required later surgery for elevated IOP, two for cataract extraction and one for repeat PK. Final visual acuity ranged from 20/20 to hand motions, depending on associated ocular damage. Best-corrected visual results were obtained in the more conservatively managed eyes. Anterior chamber epithelial cysts can be managed conservatively in selected cases with good results. This strategy may be particularly useful in children's eyes, where preservation of the lens, iris, and other structures may facilitate amblyopia management. Copyright 2003 by Elsevier Science Inc.

    Intraspinal synovial cysts of the lumbar spine are rare and commonly associated with osteoarthritis of the facet joints, particularly at level L4-L5. Symptoms are uncommon and may include low-back pain or sciatica. These cysts are accurately diagnosed by using computed tomography and magnetic resonance imaging. Diagnosis is essential for the correct management of the cysts. Several treatment options are available including rest and immobilization, computed tomography guided corticosteroid injection, and surgery in patients that are nonresponsive to other treatment methods.

    2012-02-01

    Parathyroid cysts are rare causes of neck swelling accounting for 0.6% of thyroid and parathyroid lesions. They may be functional, resulting in the release of parathyroid hormone, or non-functional. Non-functional cysts may be cosmetically unacceptable or cause dysphagia, dyspnoea or recurrent laryngeal nerve palsy as a result of compression. This article presents a young woman who was diagnosed with a thyroid cyst both on examination and imaging. However, the final histology confirmed this to be parathyroid in origin and this should be considered in the differential of such neck swellings.

    Full Text Available Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond with hyperintense signal on T1-weighted MRI. We present a case of an adult patient with rupture of an intracranial dermoid cyst, precipitated by minor trauma.

    We report a case of a large posterior mediastinal neurenteric cyst in a neonate demonstrated by chest radiographs, barium swallow examination, ultrasonography and CT of the thorax. All the investigations revealed a large posterior mediastinal cystic mass with vertebral anomalies in the form of scoliosis and hemivertebra. The cyst was completely excised by a right posterolateral thoracotomy and biopsy showed the features of a neurenteric cyst. The rarity of the lesion prompted us to report this case Copyright (2005) Blackwell Publishing Asia Pty Ltd

    Full Text Available Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options.

    Full Text Available The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often related with the more frequently branchial cyst in young adults, but also rarely related with thyroid carcinomas. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland.

    Full Text Available Squamous cell carcinoma (SCC arising from odontogenic cyst lining is rare. The exact incidence of carcinoma arising in odontogenic cyst is unknown, but it is estimated to vary between 1 and 2/1000. The pathogenesis is unknown, but a long-standing inflammation and continuous intracystic pressure have been suggested as possible causative factors. Metastasis from these lesions is not common (< 20%, and most of the carcinomas are moderately to well differentiated. To qualify as a primary intraosseous carcinoma, there must be no initial connection with the oral mucosa, overlying skin, or antral or nasal mucosa. This paper presents a case of primary intraosseous carcinoma arising from odontogenic keratocyst in the anterior mandible with metastasis to left parotid lymph nodes.

    We recently encountered two large intrasellar arachnoid cysts extending to the suprasellar region. The intensity of the cyst contents was identical to that of the cerebrospinal fluid on both T1- and T2-weighted MRI. On contrast-enhanced MRI, the pituitary gland was compressed posteroinferiorly and flattened in the sella turcica. In this report of rare intrasellar arachnoid cysts the discussion is focused on dislocation of the pituitary gland. (orig.)

    Objective: To present the prevalence and imaging findings of patients with hydatid disease (HD) showing features of migration or herniation of the hydatid cysts (HCs) and underline the clinical significance of this condition. Materials and methods: Between May 2003 and June 2006, 212 patients with HD were diagnosed by abdomen and/or thorax CT, searched for migrating or herniating HC. Imaging findings of 7 patients (5 women, 2 men with an age range of 19-63 years; mean ± S.D., 44 ± 19 years) with HD showing transdiaphragmatic migration (6 subjects) or femoral herniation (1 subject) were evaluated. Diagnosis of all the patients were established by pathologic examination and migration or herniation was confirmed by surgery in all patients. Results: Liver HD were identified in 169 (79.7%) of 212 patients with HD. Transdiaphragmatic migration of HCs were identified in 6 (3.5%) of the 169 patients with liver HD. In one patient, femoral herniation of the retroperitoneal HC into the proximal anterior thigh was identified. All of these seven patients exhibiting migration or herniation of HCs had active HCs including 'daughter cysts'. Two patients had previous surgery because of liver HD and any supradiaphragmatic lesion was not noted before operation. Findings of migration or herniation were confirmed by surgery. Conclusion: Active HCs may show migration or herniation due to pressure difference between the anatomic cavities, and in some of the patients, by contribution of gravity. Previous surgery may be a complementary factor for migration as seen in two of our patients. The possibility of migration or herniation in patients with HD should be considered before surgery

    2012-01-01

    Full Text Available Botryoid odontogenic cyst (BOC is considered to be a polycystic variant of the lateral periodontal cyst (LPC as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    We describe two patients with cyst-like lesions of bone that developed at sites of healed or healing fractures. One case showed histological features of a unicameral bone cyst, which, to the best of our knowledge, is a previously unreported finding in a post-traumatic cyst. It is suggested that there are two principal clinical and radiological types of post-traumatic cyst, of which each of our cases represents an example: (1) asymtompatic transient cortical lesions, found only in children, and (2) more central expanding lesions, found in a wider age group and associated with pain, swelling, and pathological fractures.

    Full Text Available Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic molecules. Thus, the objective of this study was to evaluate BRAF mutations in salivary gland carcinomas. Methods: We designed PCR- RFLP (Polymerase Chain Reaction -Restriction Fragment Length Polymorphism and screened 50 salivary gland carcinomas (SGCs including mucoepidermoid carcinoma (MEC, adenoid cystic carcinoma (AdCC and polymorphous low grade adenocarcinoma (PLGA for the BRAF V600E mutation. Results: PCR-RFLP analyses demonstrated no mutation in BRAF exon 15 for SGC samples at position V600, which is the most commonly mutated site for BRAF in human cancer. Conclusions: According to our results SGCs didn’t acquire BRAF mutations that result in a constitutive activation of the signaling cascade downstream of EGFR, hence SGCs can be a good candidate for anti EGFR therapies.

    1999-01-01

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

  10. Medical image of the week: bronchogenic cysts

    2018-03-01

    Full Text Available Bronchogenic cysts are congenital foregut malformations forming from abnormal budding of the bronchial tree between the 4th and 6th weeks of embryonic development. While identified primarily in children, the cysts are often asymptomatic and may not be identified until adulthood. Most (70% are within the middle mediastinum and contain fluid or proteinaceous material. When involving the parenchyma, they generally do not communicate with the tracheobronchial tree. Communication with the airways may develop following infection, procedures, or trauma and may result in lesions with an air-fluid level (Figures 1 and 2. Bronchogenic cysts may be complicated by infection, bleeding, fistula formation, or most concerning, by malignant transformation. Unless the cyst contains air, it may manifest as a solitary pulmonary nodule on plain radiographs. Computed tomography or T2-weighted MRI images are used to confirm the diagnosis.

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

    An air-filled paratracheal cyst is a common radiological finding. It may be a congenital defect or an acquired lesion. 'Acquired paratracheal cyst' is the term given to the acquired abnormalities, which usually arise in adults. They result from a weakness of the tracheal wall, and they may be caused by trauma, infection, high pressure injuries, long lasting tracheostomy, and obstructive tracheal disease. Majority of the paratracheal air cysts are asymptomatic and are discovered incidentally on radiological images. Also, the management is primarily conservative treatment. Here, we report a case of an infected paratracheal air cyst on the right posterolateral wall of the trachea, which developed into an abscess and was visualized on follow-up multidetector computed tomography and was surgically removed due to persistent symptoms

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    Full Text Available The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved.

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    Full Text Available Ventriculoperitoneal (VP shunt is one of the commonest procedures done in neurosurgical practice throughout the world. One of the commonest problems after putting the VP shunt is the shunt obstruction, which can be due to varied causes. Shunt obstruction secondary to the parasitic infections is rarely seen. We are presenting a 15-year-old child, a case of operated cerebral hydatid cyst with hydrocephalus. She presented with shunt malfunction after 1 year of surgical excision of the hydatid cyst. Revision of the VP shunt was done and peroperatively, it was found that the shunt tubing was obstructed due to small hydatid cysts. This is the first reported case of VP shunt obstruction by hydatid cyst.

    Full Text Available A 21-year-old male with developmental delay presented with abdominal pain of two days' duration. He was afebrile and his abdomen was soft with mild diffuse tenderness. There were no peritoneal signs. Plain x-ray demonstrated a large air-filled structure in the right upper quadrant. Computed tomography of the abdomen revealed a 9×8 cm structure adjacent to the hepatic flexure containing an air-fluid level. It did not contain oral contrast and had no apparent communication with the colon. At operation, the cystic lesion was identified as a duplication cyst of the sigmoid colon that was adherent to the right upper quadrant. The cyst was excised with a segment of the sigmoid colon and a stapled colo-colostomy was performed. Recovery was uneventful. Final pathology was consistent with a duplication cyst of the sigmoid colon. The cyst was attached to the colon but did not communicate with the lumen.

    Full Text Available A 28 years old male presented with a case of painless soft fluctuant swelling of right parotid gland is reported to our hospital. The lesion was found to be a cystic lesion through the pre - operative examinations and investigations. The cyst was completely excised, taking care not to injure the lower division of the facial nerve. Po st recovery was uneventful with no defect of the facial nerve functions. The histologic picture confirmed that the cyst was lymphoepithelial cyst which is so called “branchial cyst”. Through the literature reviews of parotid lymphoepit h elial cyst the discu ssions on prevalence, origin, diagnosis, histological finding, investigation and the modes of treatment are made. The ultra sound was found to be valuable in the pre - operative evaluation of the parotid swelling furthermore it is non - invasive, harmless, pai nless and relatively quick

    Pancreatic cancer is the most lethal cancer with an overall 5-year survival rate of 7%1 due to the late stage at diagnosis and the ineffectiveness of current therapeutic strategies. Given the poor prognosis, early detection at a pre-cancerous stage is the best tool for preventing this disease. Intraductal papillary mucinous neoplasms (IPMN), cystic tumors of the pancreas, represent the only radiographically identifiable precursor lesion of pancreatic cancer and are known to evolve stepwise from low-to-high-grade dysplasia before progressing into an invasive carcinoma. Observation is usually recommended for low-risk (low- and intermediate-grade dysplasia) patients, while high-risk (high-grade dysplasia and invasive carcinoma) patients undergo resection; hence, patient selection is critically important in the management of pancreatic cysts.2 Radiologists use standard criteria such as main pancreatic duct size, cyst size, or presence of a solid enhancing component in the cyst to optimally select patients for surgery.3 However, these findings are subject to a radiologist's interpretation and have been shown to be inconsistent with regards to the presence of a mural nodule or solid component.4 We propose objective classification of risk groups based on quantitative imaging features extracted from CT scans. We apply new features that represent the solid component (i.e. areas of high intensity) within the cyst and extract standard texture features. An adaptive boost classifier5 achieves the best performance with area under receiver operating characteristic curve (AUC) of 0.73 and accuracy of 77.3% for texture features. The random forest classifier achieves the best performance with AUC of 0.71 and accuracy of 70.8% with the solid component features.

    Bilateral cerebellopontine angle (CPA) arachnoid cysts (ACs) are very rare: only one case is reported in literature. Pathogenesis of those cysts is unknown; they are thought to be congenital. The presenting symptoms of CPA AC are frequently nonspecific or otological. The management of ACs of the CPA is controversial. We are reporting two cases of bilateral CPA AC with their pathophysiology and review of literature.

    The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone) or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of t...

    Cancer cells experience higher oxidative stress from reactive oxygen species (ROS) than do non-malignant cells because of genetic alterations and abnormal growth; as a result, maintenance of the antioxidant glutathione (GSH) is essential for their survival and proliferation. Under conditions of elevated ROS, endogenous L-cysteine (L-Cys) production is insufficient for GSH synthesis. This necessitates uptake of L-Cys that is predominantly in its disulfide form, L-cystine (CSSC), via the xCT(-) transporter. We show that administration of an engineered and pharmacologically optimized human cyst(e)inase enzyme mediates sustained depletion of the extracellular L-Cys and CSSC pool in mice and non-human primates. Treatment with this enzyme selectively causes cell cycle arrest and death in cancer cells due to depletion of intracellular GSH and ensuing elevated ROS; yet this treatment results in no apparent toxicities in mice even after months of continuous treatment. Cyst(e)inase suppressed the growth of prostate carcinoma allografts, reduced tumor growth in both prostate and breast cancer xenografts and doubled the median survival time of TCL1-Tg:p53 -/- mice, which develop disease resembling human chronic lymphocytic leukemia. It was observed that enzyme-mediated depletion of the serum L-Cys and CSSC pool suppresses the growth of multiple tumors, yet is very well tolerated for prolonged periods, suggesting that cyst(e)inase represents a safe and effective therapeutic modality for inactivating antioxidant cellular responses in a wide range of malignancies.

    The soybean cyst nematode (SCN), Heterodera glycines, causes economically significant damage to soybeans (Glycine max) in many parts of the world. The cysts of this nematode can remain quiescent in soils for many years as a reservoir of infection for future crops. To investigate bacterial communities associated with SCN cysts, cysts were obtained from eight SCN-infested farms in southern Ontario, Canada, and analyzed by culture-dependent and -independent means. Confocal laser scanning microscopy observations of cyst contents revealed a microbial flora located on the cyst exterior, within a polymer plug region and within the cyst. Microscopic counts using 5-(4,6-dichlorotriazine-2-yl)aminofluorescein staining and in situ hybridization (EUB 338) indicated that the cysts contained (2.6 +/- 0.5) x 10(5) bacteria (mean +/- standard deviation) with various cellular morphologies. Filamentous fungi were also observed. Live-dead staining indicated that the majority of cyst bacteria were viable. The probe Nile red also bound to the interior polymer, indicating that it is lipid rich in nature. Bacterial community profiles determined by denaturing gradient gel electrophoresis analysis were simple in composition. Bands shared by all eight samples included the actinobacterium genera Actinomadura and STREPTOMYCES: A collection of 290 bacteria were obtained by plating macerated surface-sterilized cysts onto nutrient broth yeast extract agar or on actinomycete medium. These were clustered into groups of siblings by repetitive extragenic palindromic PCR fingerprinting, and representative isolates were tentatively identified on the basis of 16S rRNA gene sequence. Thirty phylotypes were detected, with the collection dominated by Lysobacter and Variovorax spp. This study has revealed the cysts of this important plant pathogen to be rich in a variety of bacteria, some of which could presumably play a role in the ecology of SCN or have potential as biocontrol agents.

  12. Primary hydatid cyst in gastrocnemius muscle

    Full Text Available Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer′s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease. In regions where hydatidosis is endemic, hydatid cyst should be included in the differential diagnosis of any unusual muscular mass.

    A 21-year-old female patient recently diagnosed with severe hypothyroidism was found to have a large ovarian cyst. In view of the large ovarian cyst, she was advised to undergo elective laparotomy in the gynaecology department. She was further evaluated in our medical out-patient department (OPD), and elective surgery was withheld. She was started on thyroxine replacement therapy, and within a period of 4 months, the size of the cyst regressed significantly, thereby improving the condition of the patient significantly. This case report highlights the rare and often missed association between hypothyroidism and ovarian cysts. Although very rare, profound hypothyroidism that can cause ovarian cysts in an adult should always be kept in the differential diagnosis to avoid unnecessary ovarian surgery. Hypothyroidism should be considered in the differential diagnosis of adult females presenting with multicystic ovarian tumours.Adequate thyroid hormone replacement therapy can prevent these patients from undergoing unnecessary and catastrophic ovarian resection.Surgical excision should be considered only when adequate thyroid replacement therapy fails to resolve ovarian enlargement.In younger women with ovarian cysts, it is also desirable to avoid unnecessary surgery so as to not compromise fertility in the future.

    1984-01-01

    Eleven patients with sharply circumscribed round to ovoid renal cysts measuring 70-90 H on CT are reported. The cysts were hyperdense on unenhanced scans, measuring 30-60 H greater than the adjacent parenchyma, and either hypodense, isodense, or hyperdense on enhanced scans. Four patients had polycystic kidney disease; of the other 7 patients, the cysts were cortical in 6 and parapelvic in 1. Eight patients had a solitary cyst and 3 had multiple cysts. Sonography demonstrated internal echoes and/or lack of increased through-transmission in 6 patients. Pathological analysis was available in 6 cases and indicated a benign, hemorrhagic renal cyst. This hyperdense CT appearance is characteristic of some hemorrhagic renal cysts, though differentiation between benign and malignant cysts requires cyst puncture and/or surgery

    The differential between aneurysmal bone cysts and unicameral bone cysts usually is clear clinically and radiographically. Occasionally there are cases in which the diagnosis is not clear. Because natural history and treatment are different, the ability to distinguish between these two entities before surgery is important. The authors reviewed, in a blinded fashion, the preoperative magnetic resonance images to investigate criteria that could be used to differentiate between the two lesions. All patients had operative or pathologic confirmation of an aneurysmal bone cyst or unicameral bone cyst. The authors analyzed the preoperative magnetic resonance images of 14 patients with diagnostically difficult bone cysts (eight children with unicameral bone cysts and six children with aneurysmal bone cysts) and correlated these findings with diagnosis after biopsy or cyst aspiration and contrast injection. The presence of a double density fluid level within the lesion strongly indicated that the lesion was an aneurysmal bone cyst, rather than a unicameral bone cyst. Other criteria that suggested the lesion was an aneurysmal bone cyst were the presence of septations within the lesion and signal characteristics of low intensity on T1 images and high intensity on T2 images. The authors identified a way of helping to differentiate between aneurysmal bone cysts and unicameral bone cysts on magnetic resonance images. Double density fluid level, septation, and low signal on T1 images and high signal on T2 images strongly suggest the bone cyst in question is an aneurysmal bone cyst, rather than a unicameral bone cyst. This may be helpful before surgery for the child who has a cystic lesion for which radiographic features do not allow a clear differentiation of unicameral bone cyst from aneurysmal bone cyst.

    Congenital rectal duplication cyst is a rare entity treated with surgical excision. Without treatment, a rectal duplication cyst may cause a variety of complications, most notably, transforming into a malignancy. We report on a 7-week-old girl who was found to have a rectal duplication cyst. The rectal duplication cyst was successfully excised laparoscopically. Rectal duplication cysts are rare alimentary tract anomalies generally discovered during childhood. Complications include symptoms arising from the cyst and the possibility of malignant degeneration. They are typically managed by surgical excision.

    Full Text Available Xanthogranulomatous pyelonephritis is a rare and peculiar form of chronic pyelonephritis and is generally associated with renal lithiasis. Its incidence is higher in females. The peculiarity of this disease is that it requires a differential diagnosis, because it can often simulate dramatic pathologic conditions. In fact, in the literature are also described cases in association with squamous cell carcinoma of the kidney The radiologic clinical findings simulate renal masses, sometimes in association with caval thrombus. We describe a case of xanthogranulomatous pyelonephritis with radiologic aspects of a complex cyst of Bosniak class III in a man 40-year old.

    Immunostaining with monoclonal antibodies was used to study and compare the cytokeratin content of odontogenic cysts and normal gingival epithelium. Two monoclonal antibodies, PKK2 and KA1, stained the whole epithelium in all cyst samples. In gingiva, PKK2 gave a suprabasal staining and KA1 reacted with all epithelial cell layers. Antibodies PKK1, KM 4.62 and KS 8.12 gave a heterogeneous staining in follicular and radicular cysts. In keratocysts and in gingiva PKK1 and KM 4.62 reacted mainly with basal cells and KS 8.12 gave a suprabasal staining. Antibodies reacting with the simple epithelial cytokeratin polypeptide No. 18 (PKK3, KS 18.18) recognized in gingiva only solitary cells compatible with Merkel cells. In a case of follicular ameloblastoma a distinct staining of tumor epithelium was revealed with these antibodies. In 2 follicular cysts, but not in other cyst types, a layer of cytokeratin 18-positive cells was revealed. KA5 and KK 8.60 antibodies, reacting exclusively with keratinizing epithelia, including normal gingiva, gave no reaction in radicular cysts, keratocysts and ameloblastoma. Two of the follicular cysts, were negative for PKK3 and KS 18.18, but reacted strongly with KA5 and KK 8.60. The present results show that odontogenic jaw cysts have distinct differences in their cytokeratin content. With the exception of some follicular cysts, they lack signs of keratinizing epithelial differentiation. Only follicular cysts appear to share with some types of ameloblastoma the expression of cytokeratin polypeptide No. 18.

    Objective: To analyse our clinical experience with CT guided percutaneous renal cysts puncture and ethanol therapy. Methods: Five hundred and ten renal cysts in 445 patients were undergone CT guided percutaneous renal cysts puncture and ethanol therapy. Among the 445 cases, 385 cases had solitary renal cyst, 53 multiple renal cysts, and 7 polycystic kidneys. The renal cysts varied in size from 1.9 to 13.5 cm in diameter. The amount of aspirated fluid varied from 3 to 780 ml. A 18-21 gauge aspiration needles were used for all patients. A 25.0% cyst volume replacement with 99.7% ethanol was approved to be appropriate. Results: 427 renal cysts in 396 patients were followed up by computed tomographic (CT) or ultrasound for less than 3 months to more than one year duration. The curative effective rate and disappearance rate of the renal cystic cavity in solitary renal cysts were 97% and 82%, respectively. In multiple renal cysts, the corresponding values were 95% and 79%. In polycystic kidneys, the curative rate was 67%. The complications such as local abdominal pain (28 cases) and hematuria (four cases) were observed in this series. There were no fatal complications. Conclusions: CT guided percutaneous renal cyst puncture and ethanol therapy is an useful procedure for the treatment of solitary renal cysts and multiple renal cysts

    To evaluate the frequency of a paratracheal cyst on CT in an adult, and to compare the degree of loculation and the patient's age with the longest diameter of the air cysts. Of 1520 patients, who underwent a CT scan, 41 patients with paratracheal cysts were enrolled in this study. There were 26-males and 15 females, whose ranged from 24 to 82 years (mean, 59.8). The CT findings were evaluated to determine the relationship between the degree of loculation and the longest diameter of the air cysts. Another tracheal diverticula or an air cyst, as well as the tracheal communication were also evaluated. The longest diameter of the paratracheal air cysts was 1 cm (ρ = 0.043). The paratracheal air cysts 2 cm were multilocular. Four patients had another small tracheal diverticula, and one patient had another small paratracheal air cyst. Tracheal communication was observed in 7 patients (17%). The frequency of paratracheal air cysts in adults undergoing a CT scan was 2.7%. The longest diameter of the paratracheal air cysts was associated with the patient's age. The shape of air cysts became more multilocular as the longest diameter of the paratracheal air cysts increased. Another small tracheal diverticula or air cysts were observed in 12% of patients

The subject of the study is to determine the importance of ETS exposure for the accumulation of Pb, Be, Ba, Ca, Mg and Sr in the pharyngeal tonsils. Material and methods. The study involved 162 adenoids from boys and girls living in Tychy and Chorzów. exposed and not exposed to passive smoking. All biological samples were subjected to mineralization with nitric acid (V from Merck. The chemical composition of the samples was determined by the ICP – AES method. Results. The statistical analysis of the elements in the tonsils of children exposed and not exposed to ETS is performed taking into account as an additional criterion of distribution the place of residence and gender of the children. Conclusions. There was no significant effect of passive smoking on the increase of the examined metals in the adenoid. However the role of gender and place of residence to the process of accumulation of elements in this organ remains significant.

  9. Spontaneously resolving macular cyst in an infant

    Full Text Available The purpose of this study is to describe transient macular cysts in an infant and correlate their occurrence with normal development events. A newborn Caucasian girl presented with a protruding corneal mass in her left eye at birth. She underwent a complete ophthalmic examination. A keratinized staphylomatous malformation involving the entire cornea and precluding further visualization of the anterior and posterior segment was observed in the left eye. Spectral domain optical coherence tomography (SD-OCT of the right eye performed when the child was approximately 6-week-old had revealed an unexpected finding of macular cysts involving the inner nuclear and outer retinal layers. Corneal transplant in the left eye was performed a month later. Ocular examination under anesthesia just prior to surgery revealed normal intraocular pressure, anterior segment and retina in the right eye. SD-OCT was normal in both eyes and showed complete resolution of the cysts in the right eye. The patient had not been on any medications at that time. Although clinical retinal examination might be unremarkable, SD-OCT may reveal cystic spaces in the macula. In the absence of conditions known to be associated with macular edema, transient macular cysts may arise due to a developmental incompetence of the blood-retinal barrier or may represent transient spaces created during normal migration of retinal cells. Further study is warranted to delineate the entity of transient macular cysts in infancy.

    Full Text Available We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

    CT and MR images of 8 patients with supratentorial arachnoid cyst complicated by subdural hematoma were studied and compared with those of 8 patients who developed nontraumatic subdural hematoma without arachnoid cyst. Ot the 8 patients with supratentorial arachnoid cyst, CT and MR disclosed temporal bulging and/or thinning of the temporal squama in all 6 patients with middle fossa arachnoid cysts, and the thinning of the calvaria was evident in another patient with a convexity cyst. Calvarial thinning at the site corresponding to interhemispheric arachnoid cyst was clearly depicted on coronal MR images. In contrast, none of the 8 young patients with nontraumatic subdural hematoma without arachnoid cyst had abnormal calvaria. Temporal bulging and thinning of the overlying calvaria were identified as diagnostic CT and MR features of arachnoid cyst with complicating intracystic and subdural hermorrhage. Radiologists should be aware of this association and should evaluate the bony structure carefully. (orig.)

    Supratentorial endodermal cysts are very rare pathological entities. Their pathoembryology is largely unknown and they can represent a diagnostic challenge. A research performed on the PubMed database in December 2010, to screen for supratentorial endodermal cyst studies, demonstrated that since 1960 only 31 supratentorial endodermal cysts have been described in the literature, including our case: a 42-year-old woman with a parasellar endodermal cyst. These lesions are usually benign. As with other types of brain cysts, the signs and symptoms caused by supratentorial endodermal cysts are mainly linked to the compression or irritation of surrounding neural structures. Upon neuroimaging examination, they typically appear as a round or lobulated mass. The signal intensity may vary depending on the protein content of the cyst. The majority of reported supratentorial endodermal cysts were completely excised with good or excellent results. Incomplete excision can result in an increased risk of recurrence, infection, and dissemination. Georg Thieme Verlag KG Stuttgart · New York.

    2011-01-01

    The aim of this case study is to present effectiveness of percutaneous drainage as a treatment option of ruptured lung and liver hydatid cysts. A 65-year-old male patient was admitted with complicated liver and lung hydatid cysts. A liver hydatid cyst had ruptured transdiaphragmatically, and a lung hydatid cyst had ruptured both into bronchi and pleural space. The patient could not undergo surgery because of decreased respiratory function. Both cysts were drained percutaneously using oral albendazole. Povidone–iodine was used to treat the liver cyst after closure of the diaphragmatic rupture. The drainage was considered successful, and the patient had no recurrence of signs and symptoms. Clinical, laboratory, and radiologic recovery was observed during 2.5 months of catheterization. The patient was asymptomatic after catheter drainage. No recurrence was detected during 86 months of follow-up. For inoperable patients with ruptured liver and lung hydatid cysts, percutaneous drainage with oral albendazole is an alternative treatment option to surgery. The percutaneous approach can be life-saving in such cases.

    Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. (orig.)

    Katz, L B; Ehya, H

    1990-01-01

    Peculiar ring-like structures identified as Liesegang rings (LRs) were found in renal cyst fluid from three patients with benign renal cysts. They ranged in size from 5 to 820 mu. Most had a double-layer outer wall with equally spaced radial cross-striations and an amorphous central nidus. Special stains were performed in one case, and the results are discussed. Reports of LRs in cystic or inflamed tissues have recently appeared in the literature. Some LRs have been mistaken for eggs or mature components of the giant kidney worm, Dioctophyma renale. We propose that cytologic assessment of renal cyst fluid in conjunction with histologic examination decreases the likelihood of misdiagnosis of LRs.

    2012-12-01

    Full Text Available The objective of this study was to describe a case of a lymphoepithelial cyst in the palatoglossus arch. A 16-years-old black man said that he was observed a lesion in his mouth. On the physical exam, a pedicled, consistent, smooth surface 1.5 x 1 cm lesion, similar in color to the adjacent mucosa, was found. The lesion was surgically removed and the microscopic exam showed mucosal fragments with pedicled lesion; the cystic cavity sometimes lined with pseudostratified cylindrical epithelium and others with stratified squamous flat interface of the epithelium. Around the cyst, a well-delimited mass of lymphoid tissue, presenting lymphoid follicles, was also seen. Lymphoepithelial cyst has clinical characteristics similar to those of others lesions that occur in the oral cavity. The diagnosis should be based on conservative biopsy, with total removal of lesion.

  11. Nasolacrimal drainage system cyst in an adult.

    1996-01-01

    A cyst of the nasolacrimal drainage system (NLDS) is rare in an adult. We report a case in a 29-year-old man of a mucous retention cyst of the NLDS, which appeared 2 years after the patient developed dacryocystitis coincident with an aggravation of chronic sinusitis. The lesion was successfully managed by removing the bony wall of the NLDS at the interface with the ethmoid and nasal cavity, as well as the membranous closure of the ostium of the common canaliculus. We speculate that the cyst development might have been initiated by inflammatory change such as mucosal adhesion in the NLDS resulting from the spread of secondary infection from the sinonasal tract.

    1997-01-01

    Lumbar and intraneural synovial cysts are uncommon lesions. although their incidence has increased since the introduction of MRI. The authors describe the results of a study comprising 23 patients with synovial cyst (5 lumbar, 19 intraneural). Neuroradiological investigations included CT scan and MRI; however, it was not always possible to diagnose the nature of the lesion. In 18 cases the lesion was removed totally including its capsule; in the other 5 cases it was removed subtotally. Seven of the 23 patients presented a total remission of symptoms/signs, 11 improved and 5 remained unchanged. The importance of treating synovial cysts as radically as possible is discussed together with their most significant clinical and neuroradiological aspects. (author)

    Full Text Available Hydatid disease is an ancient endemic parasitic infestation caused by Echinococcus granulosus, which results in the formation of hydatid cysts in various parts of the body, the liver, and lungs being the most common sites. However, in 15% to 20% of the cases it may occur in unusual sites. We report a 25-year-old male patient who presented with clinical features similar to scrofuloderma in the axillary region but confirmed from histological examination to have hydatid cyst. This case highlights the uncommon site of hydatid cyst and unusual clinical and histopathological features along with the fact that it should be kept in differential diagnosis of nodules and sinuses in the axillary region. The treatment of choice is excision along with combination of albendazole and praziquantel.

    Enteric duplication is a rare developmental malformation in people, dogs and cats. The purpose of the present report is to describe the first case of a rectal duplication cyst in a 7-year-old domestic shorthair cat presenting for acute constipation and tenesmus. On rectal palpation a spherical mass compressing the lumen of the rectum could be felt in the dorsal wall of the rectum. A computed tomography (CT) scan confirmed the presence of a well demarcated cystic lesion in the pelvic canal, dorsal to the rectum. The cyst was surgically removed via a perineal approach. No communication with the rectal lumen could be demonstrated. Histopathological examination was consistent with a rectal duplication cyst. Clinical signs resolved completely after excision of this conjoined non-communicating cystic rectal duplicate. Copyright © 2010 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

    We present a 29-year-old woman who was admitted to the emergency department with shortness of breath. Using echocardiography, a giant multi-cystic mass was detected in the right ventricle, attached to the septal leaflet of the tricuspid valve and basal portion of the interventricular septum. Serologic tests (hydatid cyst antibody) confirmed Echinococcus infection. Lung computed tomography with intravenous contrast showed involvement of the pulmonary vasculature. The patient underwent cardiac surgery and the large cardiac cyst and the one in the right pulmonary artery branch were both removed. The tricuspid valve was also replaced by a bioprosthetic one. Albendazole was started preoperatively and was continued for six months after surgery. The patient recovered uneventfully and was followed up for one year. This is a report of a rare case of a very large cardiac hydatid cyst complicated by pulmonary embolism with attachments to both the tricuspid valve and interventricular septum.

  17. Intracranial neurenteric cyst traversing the brainstem

    Directory of Open Access Journals (Sweden)

    Jasmit Singh

    2015-01-01

    Full Text Available Neurenteric cysts (NECs, also called enterogenous cysts, are rare benign endodermal lesions of the central nervous system that probably result from separation failure of the notochord and upper gastrointestinal tract. Most frequently they are found in the lower cervical spine or the upper thoracic spine. Intracranial occurrence is rare and mostly confined to infratentorial compartment, in prepontine region [51%]. Other common locations are fourth ventricle and cerebellopontine angle. There are few reports of NEC in medulla or the cerebellum. Because of the rarity of the disease and common radiological findings, they are misinterpreted as arachnoid or simple cysts until the histopathological confirmation, unless suspected preoperatively. We herein report a rare yet interesting case of intracranial NEC traversing across the brainstem.

    Full Text Available Thornwaldt's bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx that is produced by persistent notochord remnants. If its opening becomes obstructed, possibly due to infection or a complication from adenoidectomy, a Thornwaldt's cyst might develop. Here, we present a 53-year-old man who complained of nasal obstruction that had progressed for 1 year. Nasopharyngoscopy showed a huge nasopharyngeal mass. Thornwaldt's cyst was suspected. Magnetic resonance imaging showed a lesion measuring 3.6 × 3.4 cm, intermediate on T1-weighted and high signal intensity on T2-weighted imaging, neither bony destruction nor connection to the brain. The patient underwent endoscopic surgery for this huge mass. Afterwards, his symptoms improved significantly. We present the treatment and differential diagnosis of a nasopharyngeal cyst.

    A three-year-old male Siberian Husky dog was referred to the Veterinary Teaching Hospital in Osaka Prefecture University with a complaint of difficulty in expelling the stools. By rectal examination, a mass as big as a fist could be detected occupying the cavum pelvis. Radiographically the mass had a thin bony shell bulging from the pubic periosteum. In the shell, radiolucent trabeculation gave the area a ''soap bubble'' appearance. The cut surface of the removed mass showed a honeycomb-like pattern constituted of some small loculate bony cysts. These cysts were separated from each other by a fibrous or bony trabeculae with blood-filled vascular channels or sponge-like structures. From clinical and pathological findings, this mass was diagnosed as a pelvic aneurysmal bone cyst. After surgery, the patient completely recovered without tenesmus

    Full Text Available Postoperative maxillary cyst is a quite rare delayed complication of surgical intervention associated with maxillary sinuses. It occurs many years after surgery. This paper describes a 54-year-old woman presenting with swelling of left cheek for seven-years duration. The orthopantomograph revealed a unilocular cystic radiolucency with well-defined margins in left maxillary sinus. In the computerized tomography, the cyst had a sclerotic wall with bony condensations. Aspiration cytology revealed many neutrophil leukocytes. Cyst was drained and enucleated. Histopathologically, it had a fibrous wall with inflammation and focal reactive bone formation and lined by a respiratory-type epithelium. In the clinical history, it is learned that she had a maxillary sinus surgery 8 years ago and the diagnosis was made considering the clinical and histopathological findings.

    Full Text Available Background. Microcystic variant of urothelial carcinoma is one of the new variants of urothelial carcinoma that was added to the WHO classification in 2004. Aims. To review the literature on microcystic variant of urothelial carcinoma. Methods. Various internet search engines were used to identify reported cases of the tumour. Results. Microscopic features of the tumour include: (i Conspicuous intracellular and intercellular lumina/microcysts encompassed by malignant urothelial or squamous cells. (ii The lumina are usually empty; may contain granular eosinophilic debris, mucin, or necrotic cells. (iii The cysts may be variable in size; round, or oval, up to 2 mm; lined by urothelium which are either flattened cells or low columnar cells however, they do not contain colonic epithelium or goblet cells; are infiltrative; invade the muscularis propria; mimic cystitis cystica and cystitis glandularis; occasionally exhibit neuroendocrine differentiation. (iv Elongated and irregular branching spaces are usually seen. About 17 cases of the tumour have been reported with only 2 patients who have survived. The tumour tends to be of high-grade and high-stage. There is no consensus opinion on the best option of treatment of the tumour. Conclusions. It would prove difficult at the moment to be dogmatic regarding its prognosis but it is a highly aggressive tumour. New cases of the tumour should be reported in order to document its biological behaviour.

  2. Development of the yellow potato cyst nematode Globodera rostochiensis (Woll.) on potatoes after gamma irradiation of cysts

    Karnkowski, W.; Ignatowicz, S.

    1999-01-01

    Gamma irradiation inhibited the development of the yellow potato cyst nematode, Globodera rostochiensis (Woll.) Behrens when cysts containing juveniles in anabiosis were irradiated with a dose of 0.5 kGy or higher. A dose of 0.5 kGy reduced the infestation level and the density of females/cysts on root of infested plants. However, a few cysts were found on roots of plants grown in pots with soil treated with a dose of 3.0 kGy. Development of the second generation of the potato cyst nematode (= F1 cysts that originated from irradiated cysts) was much weaker than that of the parental generation. The F1 females and/or cysts were found only in the control and in the 0.5 kGy treatment in low numbers. (author)

    20 radicular cysts of primary teeth mimicking dentigerous cyst were reviewed. The following results were obtained. 1. The patients' age ranged from 7 to 14 years. Males(60%) were more involved than females (40%). 2. The mandible (85%) was affected more frequently than the maxilla (15%). The mandibular deciduous molar area (80%) was the most frequently involved. 3. The diameter of the cyst varied from 10 to 30 mm. 55% of permanent successors showed underdeveloped roots less than one-third. 4. The etiologic factors were pulp-treated teeth (65%), severe caries (20%), trauma (10%), deep amalgam filling (5%).

  4. A lymphoepithelial cyst (branchial cyst) in the floor of the mouth.

    Kumara, G R; Gillgrass, T J; Bridgman, J B

    1995-03-01

    Lymphoepithelial cysts are developmental, but their pathogenesis is unknown. The classical explanation is that they are derived from remnants of the branchial arches or clefts. This has been disputed, and it is likely that most arise from epithelium, possibly of tonsillar or salivary origin, that becomes entrapped by lymphoid tissue. This report describes a lymphoepithelial cyst in a 29-year-old man. The cyst was situated on the right side of the floor of the mouth adjacent to the lingual frenum. Its appearance supports both branchiogenic and the entrapment theories.

  7. Supratentorial neurenteric cyst: Analysis of 45 cases in the literature

    Directory of Open Access Journals (Sweden)

    Pedro Góes, M.D.

    2018-03-01

    Conclusions: S-NC are rare and challenging lesions. The radiological features are nonspecific, and it is difficult to differentiate enterogenous cysts from other cystic lesions such as arachnoid cyst, epidermoid or glioependymal cyst. In cases with mass effect and refractory symptoms, surgical removal is indicated, including liquid drainage, capsule removal and cisternal communication. Resection of these lesions is associated with favorable outcomes.

    Ganglion cysts are fibrous-walled cystic lesions closely associated with joint or tendon sheaths and contain gelatinous mucinous fluid. The radiographic appearance is usually normal. Calcification or ossification in these cysts is extremely unusual. We report on an unusual appearing ganglion cyst of the little finger in a swimmer with ossification resembling myositis ossificans.

    African Journals Online (AJOL)

    diagnosis of the origin of the cyst is not always clear; the differential diagnosis includes choledocal, mesenteric, urachal and enteric duplication cysts, hydrometrocolpos and lymphangioma.4 A cyst shown on ultrasound scan to be echo free can sometimes be necrotic.4 A laparoscopic procedure eliminates this uncertainty.

    We present a case of lymphoepithelial cyst of the pancreas. The cyst showed moderate echogenicity, mimicking a solid lesion on ultrasonography (US), and had a cystic appearance on computed tomography (CT). This ambivalent finding may be a distinctive feature of lymphoepithelial cysts of the pancreas

    We present the MR imaging findings in a patient who developed tetraventricular hydrocephalus after massive rupture of dermoid cysts with generalized subarachnoid and ventricular spread of cyst contents. The development of tetraventricular hydrocephalus due to ruptured dermoid is a very unusual complication, and was attributed to cyst contents interfering with passage of cerebrospinal fluid through the arachnoid granulations and fourth ventricular outlet foramina.

    Degenerative cysts of the lumbar spine encompass a heterogeneous group of cystic lesions that are presumed to share a common aetiology. Some of these cysts may be incidental findings, whereas others may produce acute or chronic symptoms. These cysts have been categorized using various combinations of topographic and pathological characteristics and by their attachment to or communication with a specific spinal structure

    Giant ovarian cysts, ≥15 cm in diameter, are quite rare in women of reproductive age. Here, we present a case of ovarian cyst with unusual presentation treated by laparoscopic surgery. On histology, mass was found to be mature cystic teratoma. The diagnostic and management challenges posed by this huge ovarian cyst were discussed in the light of the literature.

  19. Low-grade salivary duct carcinoma or low-grade intraductal carcinoma? Review of the literature.

    Low-grade salivary duct carcinoma (LG-SDC) is a rare neoplasm characterized by predominant intraductal growth, luminal ductal phenotype, bland microscopic features, and favorable clinical behavior with an appearance reminiscent of florid to atypical ductal hyperplasia to low grade intraductal breast carcinoma. LG-SDC is composed of multiple cysts, cribriform architecture with "Roman Bridges", "pseudocribriform" proliferations with floppy fenestrations or irregular slits, micropapillae with epithelial tufts, fibrovascular cores, and solid areas. Most of the tumor cells are small to medium sized with pale eosinophilic cytoplasm, and round to oval nuclei, which may contain finely dispersed or dark condensed chromatin. Foci of intermediate to high grade atypia, and invasive carcinoma or micro-invasion have been reported in up to 23 % of cases. The neoplastic cells have a ductal phenotype with coexpression of keratins and S100 protein and are surrounded by a layer of myoepithelial cells in non-invasive cases. The main differential diagnosis of LG-SDC includes cystadenoma, cystadenocarcinoma, sclerosing polycystic adenosis, salivary duct carcinoma in situ/high-grade intraductal carcinoma, and papillary-cystic variant of acinic cell carcinoma. There is no published data supporting the continuous classification of LG-SDC as a variant of cystadenocarcinoma. Given that most LG-SDC are non-invasive neoplasms; the terms "cribriform cystadenocarcinoma" and LG-SDC should be replaced by "low-grade intraductal carcinoma" (LG-IDC) of salivary gland or "low-grade intraductal carcinoma with areas of invasive carcinoma" in those cases with evidence of invasive carcinoma.

    Full Text Available Congenital cystic adenomatoid malformations (CCAM are rare developmental anomalies of the lung characterized by cysts of varying sizes and/or adenomatoid proliferation. Type I CCAM, the most frequent subtype, is associated with an increased incidence of malignant transformation, principally bronchioloalveolar carcinoma, with a reported incidence of around 1%. We report the first case of mucoepidermoid carcinoma arising in a type 1 CCAM.
