    1985-04-01

    In 1978, Pratt challenged the otolaryngology community to identify an incidence of malignancy in individuals who have previously received radium therapy to the nasopharyngeal lymphoid tissues. This case report is a direct response to that quest and presents a well documented adenoid cystic carcinoma evolving 23 years after radium applicator treatment to the fossa of Rosenmuller. Although a cause-and-effect relationship cannot be scientifically proven, the case history raises several important questions concerning the stimulating effects of radiation on the later onset of frank malignancy.

    Tamme, Tiia; Leibur, Edvitar; Kulla, Andres

    2003-12-01

    We report the case of a 74-year-old woman who developed a follicular ameloblastoma of the right mandible and 22 months later developed a cribriform adenoid cystic carcinoma of the soft palate on the right maxilla. The ameloblastoma was treated by hemimandibulectomy, and the adenoid cystic carcinoma was managed by resection of the soft palate and the surrounding tissue and bone followed by a 6-week course of radiotherapy. Our review of the literature indicates that only one similar case has been previously reported where an odontogenic tumor and a salivary gland tumor involved two different anatomic locations in the same patient at nearly the same time.

    Das, Somdipto; Nayak, Umanath K; Buggavetti, Rahul; Sekhar, Shobana

    2016-05-01

    The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry. PMID:26851989

    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.

  16. Adenoid cystic carcinoma of sublingual glands. Surgery and radiotherapy combination

    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)

  17. The CT evaluation of cephalic and cervical adenoid cystic carcinoma

    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

    Adenoid cystic carcinoma (ACC) of the breast is a rare type of tumor. Our objective was to determine the clinicopathologic features of breast ACC. We reviewed slides of breast ACC reported during 12 years. Seven cases were identified. Age ranged from 38 to 59 years (mean = 47 years). Mean tumor size was 2.3 cm (range 1.2 to 4 cm). Histologically, dominant cribriform pattern was seen in 4 cases, solid in 2 and tubular in one case. Mitotic figures ranged from 2 to 22/10 HPFs. Grades I and II were seen in 3 cases each while 1 was grade III. Post-surgical tamoxifen given in 3 cases, chemotherapy and radiotherapy in 2 and 1 case, respectively. Follow-up ranged from 12.5 - 138.5 months (mean = 61. 25 months). One patient developed vertebral metastasis. Consistent with published data, this series indicated that ACC-breast has a good prognosis. PMID:27225150

    2012-01-01

    Full Text Available Adenoid cystic carcinoma (ACC occurs more commonly in the minor salivary glands of the palate on than the tongue. ACC is a malignant neoplasm that accounts for 1-2% of all head and neck malignancies and 10-15% of all salivary gland malignancies. ACC affects the exocrine glands at any site, but the parotid gland is the most common site in the head and neck region. Many factors should be taken into account in the prognosis of ACC, including the histological and clinical stages of the disease. The most striking feature of ACC is that it is locally aggressive, with a high recurrence level, perineural invasion and distant metastases, especially to the lungs and bones. The most common presentation histologically is the presence of cribriform appearance (Swiss cheese pattern. The present case is a rare one present on the tongue.

    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.

  2. Neutron radiotherapy for adenoid cystic carcinoma of minor salivary glands

    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

  3. Solid Variant of Adenoid Cystic Carcinoma: Difficulties in Diagnostic Recognition.

    2016-08-01

    Adenoid cystic carcinoma (ACC) is a malignant neoplasm that mainly affects the salivary glands but has been described in many other anatomical sites. It is composed of basaloid cells with myoepithelial/basal cell differentiation and ductal epithelial cells that proliferate in a fibrous stroma, with variable amounts of myxohyaline material. Three patterns (cribriform, tubular, and solid) occur, and the solid variant is characterized by a predominant compact sheet-like and nested pattern of rounded basaloid cells lacking obvious cribriform or tubular architecture. The solid variant has significant morphological and immunohistochemical overlap with a large range of neoplasms of different lineages, including other carcinomas and sarcomas. We describe a case of solid variant ACC of the paranasal sinuses, which showed an almost entirely solid pattern of growth (in >95% of cells) and which on initial biopsy showed no features of classical ACC. This highlights the potential for diagnostic misinterpretation with a variety of other neoplasms, which is particularly important because of the significant difference in treatment for ACC and tumors in its differential diagnosis.

  8. A subset of prostatic basal cell carcinomas harbor the MYB rearrangement of adenoid cystic carcinoma.

    Bishop, Justin A; Yonescu, Raluca; Epstein, Jonathan I; Westra, William H

    2015-08-01

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

  9. Cervical Lymph Node Metastasis: Unusual Presentation of Adenoid Cystic Carcinoma - Diagnosed By FNAC

    Archana Buch

    2015-01-01

    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.

  13. EXPRESSION OF EPIDERMAL GROWTH FACTOR RECEPTOR IN DIFFERENT SALIVARY ADENOID CYSTIC CARCINOMA CELL LINES

    MA Jie; ZONG Zhi-hong; WANG Zhao-yuan

    2005-01-01

    Objective: To investigate the expression of epidermal growth factor receptor, a receptor tyrosine protein kinase, in the subcellular fractions of human salivary adenoid cystic carcinoma cell lines SACC-83 and SACC-LM. Methods: Low metastatic and high metastatic cells of the adenoid cystic carcinoma, SACC-83 and SACC-LM, were cultured. Their subcellular fractions were extracted. The expression of epidermal growth factor receptor was detected with Western blot method, and the results of protein expression were quantitatively analyzed by FluorChem V2.0 software. Results: The results of Western blot analysis indicated that, EGFR expression on the membrane of SACC-83 cells was significantly higher than that of SACC-LM cells, but its expression in cytoplasm was significantly less in the former than the later (P<0.01). In SACC-83 cell line, EGFR was over-expressed in membrane (P<0.01), but in SACC-LM cell line, EGFR was over-expressed in cytoplasm (P<0.01). Conclusion: The results suggest that the obtaining of metastasis ability is related to the high expression of EGFR protein in cytoplasm, so the molecular targeting therapy to EGFR may be an ideal treatment for the invasion and metastasis of salivary adenoid cystic carcinoma.

The patient presented with adenoid cystic carcinoma (ACC) of the distal trachea, extending along the right main bronchus with carinal invasion. The reconstruction procedure was assisted with cross-field ventilation. Postoperative clinical course of this case was good. The forced expiratory volume in the first second (FEV1) improved from 0.461 L (17% pred.) to 2.31 L (87% pred.) 1 month after the operation. VATS tracheal resection and carinal reconstruction is a feasible option for patients with tracheal tumor with carina involvement. PMID:26904230

    Metastasis and invasion, the important characteristics of malignant tumors, are closely associated with a series of changes in the expression of genes and proteins. In this study, we compare mRNA and protein expression in high and low metastasis adenoid cystic carcinoma cell lines by mRNA suppression subtractive hybridization and two-dimensional electrophoresis combined with peptide mass fingerprint analysis. 34 differentially expressed genes were obtained using suppression subtractive hybridization experiments including 6 highly expressed gene sequences in the high metastasis cell line, and 28 in the low metastasis cell line. RNA dot blot hybridization further confirmed the results after excluding false positives. For protein analysis, ten significantly different protein spots were detected using two-dimensional gel electrophoresis technique combined with matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI- TOF-MS). The results then compare with the SWISS PROT database. These results suggest that high tumor metastasis of adenoid cystic carcinoma is associated with multiple genes whose function include angiogenesis, protein synthesis, signal transduction, modulation of cell cycle, molecular chaperones, and immune co-stimulating molecule. Moreover, the results of the phenotypic function-related expression mapping analysis at the mRNA and protein level revealed obvious complementarities, providing important clues for further study of the molecular mechanism of metastasis, metastasis control and possible targets for cancer gene therapy.

  17. Biological behavior and Treatment of Adenoid Cystic Carcinoma in the Head and Neck

    Biological Behavior and treatment results of 33 patients with Adenoid Cystic Carcinoma (ACC) in the Head and Neck at Yonsei Cancer Center for 10 years between 1971 and 1980 were retrospectively analyzed. Most common, primary site was minor salivary glands such as maxillary sinus, nasal cavity and base of tongue. The typical biological behavior of these tumors was very slowly in growth with long rime of duration (mean 19 months) from I month to 10 years and more frequent of nerve invasion but rare invasion of neck nodes. Local control and failure pattern in the results of treatment, 16 of 17 patients with irradiation alone were seen complete or partial response but 5 cases of loco regional recurrence, 2 cases of failure of neck node and 4 cases of distant metastasis as lung and brain. On the other hand, among 10 cases of surgery and postoperative irradiation, 2 cases of locoreginal failure and 3 cases of distant metastasis as lung and bone. 2 of 4 cases with surgery alone were recurred within primary site. Actuarial overall NED survival at 5 and 10 years were 52.6% and 42.8%, respectively. Survival rate of 10 patients with surgery and postoperative irradiation was more high than 17 patients of radiation alone. Therefore, we have known that surgery with postoperative adjunctive irradiation is most effective treatment modality of adenoid cystic carcinoma in the head and neck. Primary site, treatment modality and with or without nerve and bone invasion have influenced on prognosis

  18. Clinicopathological study of 54 cases of adenoid cystic carcinoma in the head and neck

    A retrospective analysis was performed on 54 patients with adenoid cystic carcinoma in the head and neck, treated from January 1971 to July l997 in the Kurume University Hospital. The patients consisted of 35 females and 19 males, with a mean age of 59 years. The site of the lesion was the oral cavity in 13, nasal cavity in 11, submandibular gland in 8, parotid gland in 5, paranasal sinus in 3, nasopharynx in 3, oropharynx in 3, external auditory canal in 3, orbita in 2, lip in 1, lacrimal gland in 1 and trachea in 1. The over all 5-year, 10-year and 15-year survival rates as determined by the Kaplan-Meier method were 72%, 53%, and 46%, respectively. There was no relationship between survival rate and the site of the original lesion. According to the histologic criteria reported by Szanto et al., when more than 30% of the neoplasma showed a solid pattern, its treatment outcome appeared poor. In this study, the same tendency was seen. Fifteen patients died of the tumor. Ten died of distant metastasis and 5 died of local recurrence invading the cranium. No patient died of neck metastasis. Adenoid cystic carcinoma was thought to be radioresistant, but recently some authors have reported this tumor as radiosensitive. This study also showed that postoperative radiotherapy was effective, producing an increase in the survival rate. (author)

  19. Lacrimal gland adenoid cystic carcinoma: intracranial and extracranial en bloc resection.

    Marsh, J L; Wise, D M; Smith, M; Schwartz, H

    1981-10-01

    Adenoid cystic carcinoma of the lacrimal gland is a rare tumor, although it is the malignancy most frequently arising in the gland. Treatment has been unsuccessful generally, with a 15-year survival of less than 20 percent. Our experience with this tumor in a 61-year-old woman has led to a proposal for therapeutic management based on awareness of the lesion's natural history, an understanding of regional anatomy, and familiarity with therapies reported in the literature. The feasibility of adequate tumor ablation is determined from preoperative evaluation, including CT scan, initial exploratory craniotomy, and frozen-section examination of the cranial nerves transversing the orbit. Once resectability is confirmed, "curative" intracranial and extracranial en bloc resection is performed, including the tumor, the lacrimal gland, and all contiguous structures. The defect is immediately resurfaced with and "ice cream cone" forehead flap in anticipation of adjuvant radiotherapy. An orbital prosthesis is fitted as soon as the radiation reaction subsides, and a postablative CT scan is obtained as the baseline for follow-up. It remains to be seen whether this application of the technology of CT scanning and the techniques of craniofacial surgery will improve the prognosis for adenoid cystic carcinoma arising in the lacrimal gland.

    2016-01-01

    Adenoid cystic carcinoma (ACC) is an infrequent malignant neoplasm of the salivary glands. We present a case of a 70-year-old male patient with a swelling over the dorsal and ventral surface of anterior two third of the tongue which was causing him difficulty in mastication since 10 months. Ultrasound and magnetic resonance imaging were done following which the surgical excision of the lesion was performed and histopathological diagnosis of ACC was achieved. It was rare to find ACC in such an old man with such a large lesion presenting so late in the rare site of the mobile tongue. ACC is a slowly growing, highly invasive cancer with a high recurrence rate and chances of metastases, so surgery is the choice of treatment with mandatory long-term follow-up. PMID:27195216

  3. Identification of acid-sensing ion channels in adenoid cystic carcinomas

    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

    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.

  5. ANTIMETASTATIC EFFECT OF INTEGRIN IIb/IIIa INHIBITORS ON SALIVARY ADENOID CYSTIC CARCINOMA

    2001-01-01

    Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studied in vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observed in vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 mg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.

    2016-10-01

    A 33-year-old woman presented with an unusual subglottic bulging mass accompanied by prolonged cough and wheeze. Laryngeal endoscopy revealed a bilateral, symmetrical mass immediately below the vocal cords with marked airway obstruction. Chronic subglottic laryngitis with inflammation or another condition such as amyloidosis was initially suspected. Cervicothoracic computed tomography revealed an obvious reduction of laryngeal caliber caused by an engulfing mass extending from just under the vocal cords to the cricoid ring, which was associated with thyroid, arytenoid, and cricoid cartilage destruction. Histopathological diagnosis of a biopsy specimen collected via a tracheotomy revealed that the lesion was a cT4aN0M0 adenoid cystic carcinoma (ACC) originating from the laryngeal minor salivary glands. The patient was treated by total laryngectomy with elective bilateral neck dissection under general anesthesia. Gross inspection of resected tissue confirmed yellowish-white, solid tumor mainly circumferentially encompassing the lumina of the cricoid ring. The histopathological findings confirmed typical ACC accompanied by a predominant cribriform appearance with no evidence of lymph node metastasis. The patient remains well and free of recurrence or metastasis. We herein describe laryngeal ACC and discuss radiological images and the surgical pathology. PMID:26803452

    2009-12-01

    Adenoid cystic carcinoma (AdCC) and polymorphous low-grade adenocarcinoma (PLGA) have several common histological and clinicopathological features that may create diagnostic difficulties. In this study, 10 AdCCs, 8 PLGAs, and 5 normal minor salivary glands as a control group were selected. Sections prepared from each tumor were stained using the streptavidin-biotin system for seven marker antigens: carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), muscle-specific actin (MSA), vimentin, S100, p53, and Ki-67. Data analysis showed high expression of CEA, MSA and Ki-67 in AdCCs compared with PLGAs, although CEA expression was limited to luminal cells. Ki-67 was expressed in both luminal and non-luminal cells and MSA only in non-luminal cells. Vimentin and S100 showed stronger expression in PLGAs, the expression of vimentin was more noticeable, being focal and widespread. The immunoreactivities of EMA and P53 were not helpful for distinguishing between the two tumors, although the EMA expression pattern in AdCCs was limited to luminal cells, whereas it was present in both luminal and non-luminal cells in PLGAs. Thus, immunohistochemistry can be helpful for differential diagnosis of AdCC and PLGA, particularly that for CEA, vimentin, and Ki-67. PMID:20032601

  10. Pattern of failure and role of radiotherapy in adenoid cystic carcinoma of the head and neck

    This retrospective study reviewed 55 patients with adenoid cystic carcinoma of the head and neck who were treated with radiotherapy for primary sites between 1980 and 1998. The treatment modality consisted of radiotherapy combined with surgery in 44 patients and radiotherapy without surgery in 11. Chemotherapy was also administered to 9 operated and 6 unoperated patients. The range of prescribed doses was 25-65 Gy (median 50 Gy) for patients who underwent surgery, and 60-70 Gy (median 65 Gy) for those who did not. Local failure occurred in 16 patients (29%), and 20 (36%) developed distant metastasis, which were common types of failure. Although not statistically significant different, local relapse free rates of early stage tumors were better than those of advanced stage tumors (p=0.08). The local relapse free rates were influenced by the primary sites (major vs. minor salivary glands) (p=0.04). These factors, however, had no impact on survival. Three patients developed recurrences in the skull base probably thorough perineural spread. Neck failure was also uncommon type of recurrence, occurring in only two patients. We also discuss elective irradiation to the neck nodes and the skull base. (author)

  11. Intracranial extension of adenoid cystic carcinoma of the palate: a case report

    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

  13. EXPRESSIONS OF P53, PROLIFERATING CELL NUCLEAR ANITIGEN, BCL-2 PROTEIN AND THEIR SIGNIFICANCE IN SALIVARY ADENOID CYSTIC CARCINOMA

    2000-01-01

    Objective To study the effects of P53, PCNA, Bcl-2 protein and their relationship in salivary adenoid cystic carcinoma(SACC). Methods These proteins were examined by immunohistochemistry. Results Overexpressions of P53 and PCNA were revealed in ACC samples, they were higher than those in (polymorphous adenomas) PA, but expression of Bcl-2 protein was not different between ACC and PA. In 3 subtypes of ACC, expressions of 3 proteins were different. Conclusion Mutations of P53, Bcl-2 may be involed in the occurrence of SACC, expression of PCNA and mutation of P53 may coexist in the development of the SACC.

  14. Management of Adenoid Cystic Carcinoma of the Breast: A Rare Cancer Network Study

    Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-up of 79 months (range, 6–285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%–100%) and 82% (95% CI, 71%–93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%–100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%–100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%–100%) for the RT group versus 83% (95% CI, 54%–100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.

  16. Adenoid cystic carcinoma of the parotid gland: Anastamosis of the facial nerve with the great auricular nerve after radical parotidectomy

    Bahadir Osman

    2008-01-01

    Full Text Available Adenoid cystic carcinoma of the parotid gland is a rare and slowly growing, but highly malignant tumor. Surgical resection of a malignant parotid tumor should include resection of the facial nerve when the nerve is involved in the tumor. Facial nerve reconstruction is required after nerve resection. A 14 year-old female presented with complaints of painless enlargement of the right parotid gland and facial asymmetry. Physical examination revealed a firm mass in the region of the parotid gland as well as right facial paralysis. Biopsy obtained from the mass showed an adenoid cystic carcinoma of the parotid gland. A radical parotidectomy with a modified radical neck dissection was carried out. Grafting material for the facial reconstruction was harvested from the great auricular nerve. The proximal main trunk and each distal branch of the facial nerve were coapted with the greater auricular nerve. The patient received radiotherapy after surgery and was seen to achieve grade IV facial function one year after surgery. Thus, the great auricular nerve is appropriate grafting material for coaptation of each distal branch of the facial nerve.

  17. Reactive oxygen species and autophagy associated apoptosis and limitation of clonogenic survival induced by zoledronic acid in salivary adenoid cystic carcinoma cell line SACC-83.

    Xi-Yuan Ge

    Full Text Available Salivary adenoid cystic carcinoma is an epithelial tumor in the head and neck region. Despite its slow growth, patients with salivary adenoid cystic carcinoma exhibit poor long term survival because of a high rate of distant metastasis. Lung and bone are common distant metastasis sites. Zoledronic acid, a third generation bisphosphonate, has been used for tumor-induced osteolysis due to bone metastasis and has direct antitumor activity in several human neoplasms. Here, we observed that zoledronic acid inhibited salivary adenoid cystic carcinoma cell line SACC-83 xenograft tumor growth in nude mice. In vitro, zoledronic acid induced apoptosis and reduced clonogenic survival in SACC-83. Flow cytometry and western blotting indicated that the cell cycle was arrested at G0/G1. Zoledronic acid treatment upregulated reactive oxygen species as well as the autophagy marker protein LC-3B. Reactive oxygen species scavenger N-acetylcysteine and autophagy antagonist 3-methyladenine decreased zoledronic acid-induced apoptosis and increased clonogenic survival. Silencing of the autophagy related gene Beclin-1 also decreased zoledronic acid-induced apoptosis and inhibition of clonogenic formation. In addition, isobolographic analysis revealed synergistic effects on apoptosis when zoledronic acid and paclitaxel/cisplatin were combined. Taken together, our results suggest that zoledronic acid induced apoptosis and reduced clonogenic survival via upregulation of reactive oxygen species and autophagy in the SACC-83 cell line. Thus, zoledronic acid should be considered a promising drug for the treatment of salivary adenoid cystic carcinoma.

    Background Due to the rarity of adenoid cystic carcinoma (ACC), information on outcome is based upon small retrospective case series. The aim of our study was to create a large multiinstitutional international dataset of patients with ACC in order to design predictive nomograms for outcome. Methods ACC patients managed at 10 international centers were identified. Patient, tumor, and treatment characteristics were recorded and an international collaborative dataset created. Multivariable competing risk models were then built to predict the 10 year recurrence free probability (RFP), distant recurrence free probability (DRFP), overall survival (OS) and cancer specific mortality (CSM). All predictors of interest were added in the starting full models before selection, including age, gender, tumor site, clinical T stage, perineural invasion, margin status, pathologic N-status, and M-status. Stepdown method was used in model selection to choose predictive variables. An external dataset of 99 patients from 2 other institutions was used to validate the nomograms. Findings Of 438 ACC patients, 27.2% (119/438) died from ACC and 38.8% (170/438) died of other causes. Median follow-up was 56 months (range 1–306). The nomogram for OS had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N-status and M-status) with a concordance index (CI) of 0.71. The nomogram for CSM had the same variables, except margin status, with a concordance index (CI) of 0.70. The nomogram for RFP had 7 variables (age, gender, clinical T stage, tumor site, margin status, pathologic N status and perineural invasion) (CI 0.66). The nomogram for DRFP had 6 variables (gender, clinical T stage, tumor site, pathologic N-status, perineural invasion and margin status) (CI 0.64). Concordance index for the external validation set were 0.76, 0.72, 0.67 and 0.70 respectively. Interpretation Using an international collaborative database we have created the first nomograms which

    Adenoid cystic carcinoma (ACC) is both invasive and clinically unpredictable, and our aim was to evaluate the factors that affect its recurrence in the palate. We retrospectively studied 38 patients who had ACC of the palate treated surgically, and the outcome measure was recurrence during the mean (SD) followup time of 55 (18) months. Age, sex, T-stage, bony involvement, duration of follow up, histological type, perineural invasion, and surgical margins were all recorded. Results showed no association between recurrence, and age or histopathological types. However, T-stage (p=0.001), sex (p=0.04), and bony and perineural involvement (p=0.01 in each case) were significantly associated with recurrent tumour. Close superior and posterior margins (< 2mm) were also associated with recurrence (p=0.001 in each case). Large tumours with bony and perineural involvement, together with close superior and posterior surgical margins, had a higher risk of recurrence. PMID:27094499

  20. An unusual presentation of adenoid cystic carcinoma of the minor salivary glands with cranial nerve palsy: a case study

    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 5th and 6th 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 5th and 6th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5th and 6th cranial nerve involvement as histopathology revealed no perineural invasion

    Jovičić-Milentijević Maja

    2011-01-01

    Full Text Available Background. We presented an unusual case of adenoid cystic carcinoma (ACC of the breast with multinucleated stromal giant cells (MSGCs. To the best of our knowledge, the occurrence of ACC with MSGCs has not been reported previously. MSGCs should be distinguished from other multinucleated giant cells in breast tumors. The histogenesis of MSGCs still remains obscure. In hope to elucidate the histogenesis of MSGCs, we used a broad range of antibodies. Case report. A 40-year-old woman presented with a palpable lump in the subareolar location of her right breast. Excision of the tumor was performed. At gross pathologic examination the tumor was 20 × 15 × 15 mm in size, redbrown and well circumscribed. The surgical margins were positive for carcinoma and skin-sparing mastectomy with axillary dissection was complited. Eighteen lymph nodes examined were uninvolved. Patohistological examination showed ACC with numerous MSGCs scattered within tumor stroma. Immunohistochemical studies indicated that MSGCs are probably derived from stromal fibroblasts. These cells showed strong reactivity only for vimentin. Staining for histiocytic marker (CD68, as well as for epithelial marker (cytokeratin, myoepithelial markers (S-100, α- smooth muscle actin, vascular marker (CD34, hormonal receptors (ER, PR and HER2 in MSGCs were negative. Conclusion. The presence of MSGCs should not alter the prognosis of an otherwise typical breast ACC.

  4. 125I brachytherapy alone for recurrent or locally advanced adenoid cystic carcinoma of the oral and maxillofacial region

    Background and purpose: This retrospective study was to evaluate the local control and survival of 125I brachytherapy for recurrent and/or locally advanced adenoid cystic carcinoma (ACC) of the oral and maxillofacial region. Patients and methods: A total of 38 patients with recurrent and/or locally advanced ACC of the oral and maxillofacial region received 125I brachytherapy alone from 2001-2010. Twenty-nine were recurrent cases following previous surgery and radiation therapy. The other 9 cases involved primary tumors. Overall, 12 tumors were located in the major salivary glands, 12 in the minor salivary glands, and 14 in the paranasal region, the nasal cavity or the skull base. The prescribed dose was 100-160 Gy. Results: Patients were followed for 12-122 months (median 51 months). The 2-, 5-, and 10-year local tumor control rates were 86.3, 59, and 31.5 %, respectively. The 2-, 5-, and 10-year overall survival rates were 92.1, 65 and 34.1 %, respectively. Tumors > 6 cm had significantly lower local control and survival rates. No severe complications were observed during follow-up. Conclusion: 125I brachytherapy is a feasible and effective modality for the treatment of locally advanced unresectable or recurrent ACC.

  6. Effects of 5-aza-2′deoxycytidine on RECK gene expression and tumor invasion in salivary adenoid cystic carcinoma

    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

    Full Text Available Background: Adenoid cystic carcinoma (ACC accounts for 1% of all head and neck (HN cancers. Materials and Methods: Demographic, clinical, treatment, and survival details of 66 patients were collected (1995-2011 and analyzed. Disease-free survival (DFS was estimated by Kaplan-Meier method. Results: Primary disease sites were sinonasal (n = 27, salivary gland (n = 30, and others (n = 9. Median follow-up was 23 months (range: 12-211 months. Estimated DFS at 2- and 5-year were 75% and 67.2%, respectively. On univariate analysis, intra-cranial extension (ICE (hazard ratio [HR]: 3.59, P = 0.0071, lymph node involvement (HR: 4.05, P = 0.0065, treatment modality (others vs. surgery plus adjuvant radiotherapy, HR: 2.39, P = 0.0286 and T stage (T3/4 vs. T1/2, HR: 3.27, P = 0.007 had significant impact on DFS. Lymph node involvement (P = 0.038 and ICE (P = 0.038 continued to have significant impact on DFS on multivariate analysis. Conclusion: Surgery followed by adjuvant radiotherapy remains the treatment of choice for HN ACC. Lymph node involvement and ICE confer poor prognosis.

    Adenoid cystic carcinoma (SACC) is a rare malignancy, but a frequent subtype in minor and major salivary glands. The molecular alterations or biomarkers that underlie its development and progression as well as therapy outcomes are poorly characterized. The main study goal was to investigate reliable biomarkers and patient-related factors that may have impact on recurrence and long-term survival of SACC. The prevalence of human papilloma virus (HPV) in SACC was determined by HPV-DNA genotyping and p16 immunostaining. Epithelial growth factor receptor (EGFR), p53 and Ki-67 expression were also evaluated. Twenty-eight (42%) of 67 patients were HPV-DNA positive. Kaplan-Meier analysis indicated that SACC patients with metastases (P=0.03) had a poor overall survival (OS) and a shorter recurrence-free survival (POS while non-metastatic disease (P=0.002), HPV positivity (P=0.041) and negative resection margin predicted a better recurrence-free survival. The present study documents for the first time the positivity for HPV infection and overexpression of certain markers (p16, Ki-67, EGFR and p53) used in diagnostics in SACC as well as characterizes clinical entities. These factors might be exploited in the future as biomarkers for its prognostic value. Using the clinical and pathological basis for predicting different outcomes could significantly facilitate SACC stratification and potentially directing treatment. PMID:27279281

    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.

    2010-11-01

    Full Text Available Abstract 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.

  12. Efficacy of sorafenib, a multi-tyrosine kinase inhibitor, in an adenoid cystic carcinoma metastatic to the lung: case report and review of literature

    Santos Edgardo S

    2011-09-01

    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.

    The purpose of this study was to suggest general guidelines in the management of the N0 neck of oral cavity and oropharyngeal adenoid cystic carcinoma (AdCC) in order to improve the survival of these patients and/or reduce the risk of neck recurrences. The incidence of cervical node metastasis at diagnosis of head and neck AdCC is variable, and ranges between 3% and 16%. Metastasis to the cervical lymph nodes of intraoral and oropharyngeal AdCC varies from 2% to 43%, with the lower rates pertaining to palatal AdCC and the higher rates to base of the tongue. Neck node recurrence may happen after treatment in 0-14% of AdCC, is highly dependent on the extent of the treatment and is very rare in patients who have been treated with therapeutic or elective neck dissections, or elective neck irradiation. Lymph node involvement with or without extracapsular extension in AdCC has been shown in most reports to be independently associated with decreased overall and cause-specific survival, probably because lymph node involvement is a risk factor for subsequent distant metastasis. The overall rate of occult neck metastasis in patients with head and neck AdCC ranges from 15% to 44%, but occult neck metastasis from oral cavity and/or oropharynx seems to occur more frequently than from other locations, such as the sinonasal tract and major salivary glands. Nevertheless, the benefit of elective neck dissection (END) in AdCC is not comparable to that of squamous cell carcinoma, because the main cause of failure is not related to neck or local recurrence, but rather, to distant failure. Therefore, END should be considered in patients with a cN0 neck with AdCC in some high risk oral and oropharyngeal locations when postoperative RT is not planned, or the rare AdCC-high grade transformation.

    2009-03-01

    Full Text Available Objective: The aim of the present study was to investigate the demographic and pathological aspects of adenoid cystic carcinomas (ACC in an Iranian sample based on a 20-year archive review.Materials and Methods: In this descriptive study, tumors of the head and neck registered between 1980 and 2000 were evaluated and cases of ACC were selected. Patients’ medical records and pathology reports were reviewed. Variables such as age, sex, duration of disease,symptoms, site of tumor involvement and tumor diameter as well as pathologic features were recorded. Analysis was performed using chi-square and t-tests; P<0.05 was considered as the level of significance.Results: ACC was the most common malignant tumor followed by mucoepidermoid carcinoma and adenocarcinoma NOS. A total of 120 ACCs were found, of which 50.8% occurred in females and 49.2% in males. Patients’ ages ranged from 5 to 90 with a mean of 49.2 (SD=15.9 years. In 60.9% of cases, minor salivary glands were involved and the palate was the most common site. The greatest tumor diameter was between 2-15cm with a mean of 4.6 cm (SD=2.9. The most prevalent histologic appearance was cribriform, followed by tubular pattern. No significant relation was observed between lymph node metastasisand patients’ age, sex, disease duration, greatest tumor diameter and site of involvement.Conclusion: Our findings were relatively similar to other reports from different parts of the world. Further analytic and case-control studies are recommended to gain a better understanding of different aspects of ACC.

  17. Bmi-1 expression predicts prognosis in salivary adenoid cystic carcinoma and correlates with epithelial-mesenchymal transition-related factors.

    Yi, Chun; Li, Bin-Bin; Zhou, Chuan-Xiang

    2016-06-01

    Salivary adenoid cystic carcinoma (AdCC) is known for its high propensity to invade and metastasize. Bmi-1 acts as an oncogene by controlling cell cycle and self-renewal of adult stem cells, and its overexpression correlates with metastasis and poor prognosis in several cancers. Epithelial-mesenchymal transition (EMT) plays a central role in cancer metastasis. A key step in EMT is the down-regulation of E-cadherin that can be repressed by the transcriptional factors, such as Snail and Slug. In the present study, we investigated Bmi-1, Snail, Slug, and E-cadherin expression by immunohistochemistry in 102 patients with AdCC and analyzed statistically whether their expression correlated with clinicopathologic factors and prognosis. Reverse transcription-polymerase chain reaction was also performed in 22 tumor tissues and the adjacent noncancerous tissues to confirm Bmi-1 status in AdCCs. Our data demonstrated significant associations between the tumor metastasis and the expression of Bmi-1, Snail, Slug, and E-cadherin. Furthermore, a high level of Bmi-1 was not only correlated with the overexpression of Snail and Slug but also indicated an unfavorable metastasis-free survival and served as a high-risk marker for AdCC. In addition, Bmi-1 messenger RNA level was found much higher in AdCC tissues than in the adjacent noncancerous salivary gland tissues. Our results suggest that Bmi-1 may play a crucial role in AdCC progression by interaction with EMT-related markers and predict poor survival. PMID:27180058

  18. Therapeutic strategies for adenoid cystic carcinoma of the nasal and paranasal sinus from the long-term treatment results

    This article presents long-term treatment results by analyzing 24 cases with adenoid cystic carcinoma (ACC) of the nasal and paranasal sinus treated from 1975 to 1995 at Akita University Hospital and Chiba University Hospital. The basic strategies for treatment for ACC of the nasal and paranasal sinuses are en bloc tumor resection, followed by primary reconstruction of the maxilla. Preoperative and postoperative radiation were combined. Cumulative 5-year and 10-year survival rates were 70.6% and 47.1% for maxillary sinus tumors, respectively. Cumulative 5-year and 10-year survival rates for nasal tumors were 100% and 75.0%, and those for sphenoid sinus tumors were 50.0% and 0%, respectively. The patient with ethomoid sinus who needed skull base surgery is alive at 8.1 years after therapy. Treatment results closely correlated with tumor extension. Cumulative 5-year survival rates for T2, T3 and, T4 patients with maxillary sinus tumors were 85.7%, 71.4%, and 33.3%, respectively. And cumulative 10-year survival rates for T2, T3, and T4 were 71.4%, 42.9%, and 0%, respectively. The histopathological effects of preoperative radiation were Shimosato II a in 6 out of 10 patients, II b in 2, and III in 2, respectively. Only fast neutron therapy reached Shimosato III. Two of the patients with Shimosato II a died of distant metastasis. The above data suggests that, although radiation therapy alone cannot cure tumors, preoperative full-dose radiation may prevent the development of distant metastasis if it can achieve histopathological effects of a higher classification than Shimosato II b. Because chemotherapy and radiation is not very effective on ACC, the role of skull base surgeries for nasal-paranasal sinus malignancies that invade the skull base is valuable, particularly in cases having a relatively small mass in the ethmoid sinus.

    2012-01-01

    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.

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

    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.

  1. Interdisciplinary treatment of the patient with adenoid cystic carcinoma of the Bartholin’s gland resulting in 15 years’ survival: a case report and review of literature

    Marek Nowak

    2014-11-01

    Full Text Available Carcinoma of the Bartholin’s gland is very rare, comprises below 2% of Bartholin’s gland lesions and adenoid cystic carcinoma (ADC is one of the most uncommon variants and accounts for 10-15% of Bartholin’s gland malignancies. There is no consensus on treatment of ADC of the Bartholin’s gland: reported cases were treated with local excision or vulvectomy with or without lymphadenectomy followed or not by radiotherapy. The survival of patients varies significantly, so we present a case of interdisciplinary treatment of ADC resulting in 15 years’ survival. The patient was initially treated with local excision, but the margins were not clear. Then vulvectomy, inguinal lymphadenectomy and adjuvant brachytherapy were performed resulting in 7 years free of the disease. Relapses were excised by abdominoperineal amputation of the rectum and distal part of the vagina with sigmoideostomy, excisions of local recurrences in vagina and metastasectomy of isolated lung metastases. The patient died manifesting multiple lung metastases 15 years after the initial diagnosis. Based on our experience and world literature, in cases of adenoid cystic carcinoma of the Bartholin’s gland, vulvectomy with or without lymphadenectomy should be considered as a treatment of choice and in patients with positive margin, surgery should be extended by adjuvant radiotherapy.

  2. Combined treatment of adenoid cystic carcinoma with cetuximab and IMRT plus C12 heavy ion boost: ACCEPT [ACC, Erbitux® and particle therapy

    Hinke Axel

    2011-02-01

    Full Text Available Abstract Background Local control in adjuvant/definitive RT of adenoid cystic carcinoma (ACC is largely dose-dependent leading to the establishment of particle therapy in this indication. However, even modern techniques leave space for improvement of local control by intensification of local treatment. Radiation sensitization by exploitation of high EGFR-expression in ACC with the EGFR receptor antibody cetuximab seems promising. Methods/design 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. Discussion The primary objective of ACCEPT is to evaluate toxicity and feasibility of cetuximab and particle therapy in adenoid cystic carcinoma.

    Salivary gland adenoid cystic carcinoma (ACC) is a rare head and neck malignancy without molecular biomarkers that can be used to predict the chemotherapeutic response or prognosis of ACC. The regulation of gene expression of oncogenes and tumor suppressor genes (TSGs) through DNA promoter methylation may play a role in the carcinogenesis of ACC. To identify differentially methylated genes in ACC, a global demethylating agent, 5-aza-2′-deoxycytidine (5-AZA) was utilized to unmask putative TSG silencing in ACC xenograft models in mice. Fresh xenografts were passaged, implanted in triplicate in mice that were treated with 5-AZA daily for 28 days. These xenografts were then evaluated for genome-wide DNA methylation patterns using the Illumina Infinium HumanMethylation27 BeadChip array. Validation of the 32 candidate genes was performed by bisulfite sequencing (BS-seq) in a separate cohort of 6 ACC primary tumors and 6 normal control salivary gland tissues. Hypermethylation was identified in the HCN2 gene promoter in all 6 control tissues, but hypomethylation was found in all 6 ACC tumor tissues. Quantitative validation of HCN2 promoter methylation level in the region detected by BS-seq was performed in a larger cohort of primary tumors (n=32) confirming significant HCN2 hypomethylation in ACCs compared with normal samples (n=10; P=0.04). HCN2 immunohistochemical staining was performed on an ACC tissue microarray. HCN2 staining intensity and H-score, but not percentage of the positively stained cells, were significantly stronger in normal tissues than those of ACC tissues. With our novel screening and sequencing methods, we identified several gene candidates that were methylated. The most significant of these genes, HCN2, was actually hypomethylated in tumors. However, promoter methylation status does not appear to be a major determinant of HCN2 expression in normal and ACC tissues. HCN2 hypomethylation is a biomarker of ACC and may play an important role in the

    Background A20, also known as tumor necrosis factor α induced protein 3 (TNFaip3), is a cytoplasmic zinc finger protein that inhibits nuclear factor kappa-B (NF-κB) activity and prevents tumor necrosis factor (TNF)-mediated programmed cell death. NF-κB is a transcription factor that regulates expression of genes involved in cell proliferation,cell survival and anti-apoptosis. Several studies have implicated that the NF-κB signal pathway is associated with angiogenesis and clinico-pathological process of adenoid cystic carcinoma (ACC) of the salivary glands.Methods The ability of overexpression of A20 to influence the biological behavior and invasion of ACC cells was examined. The cells were stably transfected with full-length A20 cDNA. Stable gene transfer was verified by realtime-polymerase chain reaction (PCR) and Western blot analysis. The change of cell biological behavior was examined by methyl thiazolyl tetrazolium (MTT) and NF-κB luciferase reporter assay and the invasion of the cells was examined by a Matrigel invasion chamber.Results pEGPFN3-A20 gene was stably transferred into ACC-2 cells and overexpressed. When cells were treated with TNFα, the NF-κB activity of ACC-2-A20 cells could be down-regulated about 46.32% in contrast to ACC-2-GFP cells (P<0.05). A20 potently inhibited growth of A20 transfectant ACC-2-A20 compared with control vector transfected groups and the ACC-2 empty control group (P<0.05). The ACC-2-A20 cells showed significantly reduced ability to invade through Matrigei-coated filters compared to ACC-2-GFP and ACC-2 cells. The inhibition rate was up to 71.05% (P<0.05).Conclusions A20 gene transfer is associated with decreased tumor invasion, in part via the down-regulation of NF-κB expression, providing evidence for a potential application of A20 in designing a treatment modality for salivary gland cancers such as ACC.

  5. The effect of proteoglycans inhibited by RNA interference on metastatic characters of human salivary adenoid cystic carcinoma

    Salivary adenoid cystic carcinoma (SACC) is one of the most common malignancies of salivary gland. Recurrence or/and early metastasis is its biological properties. In SACC, neoplastic myoepithelial cells secrete proteoglycans unconventionally full of the cribriform or tubular and glandular structures of SACC. Literatures have demonstrated that extracellular matrix provided an essential microenvironment for the biological behavior of SACC. However, there is rare study of the effect of proteoglycans on the potential metastasis of SACC. In this study, human xylosyltransferase-I (XTLY-I) gene, which catalyzes the rate-limited step of proteoglycans biosynthesis, was knocked down by RNA interference (RNAi) to inhibit the proteoglycans biosynthesis in SACC cell line with high tendency of lung metastasis (SACC-M). The impact of down-regulated proteoglycans on the metastasis characters of SACC-M cells was analyzed and discussed. This research could provide a new idea for the clinical treatment of SACC. The eukaryotic expression vector of short hairpin RNA (shRNA) targeting XTLY-I gene was constructed and transfected into SACC-M cells. A stably transfectant cell line named SACC-M-WJ4 was isolated. The XTLY-I expression was measured by real-time PCR and Western blot; the reduction of proteoglycans was measured. The invasion and metastasis of SACC-M-WJ4 cells were detected; the effect of down-regulated proteoglycans on the potential lung metastasis of nude mice was observed, respectively. The shRNA plasmid targeting XTLY-I gene showed powerful efficiency of RNAi. The mRNA level of target gene decreased by 86.81%, the protein level was decreased by 80.10%, respectively. The silence of XTLY-I gene resulted in the reduction of proteoglycans significantly in SACC-M-WJ4 cells. The inhibitory rate of proteoglycans was 58.17% (24 h), 66.06% (48 h), 57.91% (72 h), 59.36% (96 h), and 55.65% (120 h), respectively. The reduction of proteoglycans suppressed the adhesion, invasion and

  6. In vitro angiogenesis and expression of nuclear factor κB and VEGF in high and low metastasis cell lines of salivary gland Adenoid Cystic Carcinoma

    Adenoid cystic carcinoma is a high malignant carcinoma characterized by intensive local invasion and high incidence of distant metastasis. Although many reports have demonstrated that angiogenesis has played an important role in tumor metastasis, the relationship between metastasis characters and angiogenesis ability in high and low metastasis cell lines of Adenoid cystic carcinoma has rarely been reported. The present study aimed to compare the angiogenesis ability of ACC-M (high metastasis) and ACC-2 (low metastasis) cell lines in vitro. Furthermore, the activity of nuclear factor κappa B and the expression of vascular endothelial growth factor (VEGF) in ACC-2 and ACC-M were also detected. Electrophoretic mobility shift assay was used to detect nuclear factor κappa B activity. Semi-quantitative RT-PCR was used to quantify the mRNA level of VEGF. Immuofluorescence double staining and semi-quantitative confocal laser scanning analysis was carried out to detect nuclear factor κappa B nuclear localization and staining intensity of VEGF. The angiogenesis ability of ACC-M and ACC-2 was compared by an in vitro three-dimensional angiogenic model assay. The vector transfection assay was performed to transfect the PCMV-IκBαM vector into ACCs cell lines expressing the phosphorylation defective IκBαM. Nuclear factor κappa B activity and the rate of nuclear factor κappa B nuclear localization in ACC-M was significantly higher than that in ACC-2. Moreover, ACC-M exhibited higher mRNA and protein levels of vascular endothelial growth factor than ACC-2. VEGF mRNA expression was effectively decreased by inhibition of nuclear factor κappa B activity. Furthermore, ACC-M could remarkably stimulate the migration and tube formation of endothelial cells and induce The umbilical vein endothelial cells sprouting into the gel matrix. These results implicated that ACCs cells with higher metastasis feature might present greater angiogenesis ability

    2016-04-01

    We report the case of a 63-year-old woman with adenoid cystic carcinoma of the lower trachea treated by resection of 11 of the 18 cartilaginous rings (61%) of the total length. The little remaining membranous portion of the carina was sewn up to create a margin for anastomosis. The anastomotic sites could be approximated by the mobilization of the cervical trachea and the left main bronchus, pulling across the traction sutures, and anteflexion of the neck. The patient's postoperative course was uneventful without any complications associated with anastomosis. Because both the proximal and distal margins showed microscopic tumors, radiation therapy was performed with 50 Gy 2 months after surgery. The patient has a good social life without recurrence 20 months after surgery. PMID:25261213

    2014-03-01

    Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare adnexal skin tumor first described in 1975, of which merely 62 cases have so far been studied in detail and reported in the English literature. PCACC is usually regarded as apocrine in origin/differentiation, but its precise histogenesis is still not well known. PCACC has in most cases a rather indolent course but can produce local recurrences and, more rarely, regional (lymph node) and distant (pulmonary) metastases. We report herein a Greek woman with a long-standing PCACC that grew slowly over several years and produced metastasis in the regional lymph nodes, highlighting the potentially aggressive course of this tumor. The primary and metastatic tumors were studied immunohistochemically and proved to express several (sweat gland-related) antigens (such as keratin 7, epithelial membrane antigen, CD10, and CD117) but neither hormonal receptors nor p63 or Gross Cystic disease Fluid Protein 15. The salient clinicopathologic features of this rare cutaneous adnexal tumor are reviewed. PMID:23812021

  9. SIKVAV, a Laminin α1-Derived Peptide, Interacts with Integrins and Increases Protease Activity of a Human Salivary Gland Adenoid Cystic Carcinoma Cell Line through the ERK 1/2 Signaling Pathway

    2007-01-01

    Adenoid cystic carcinoma is a frequently occurring malignant salivary gland neoplasm. We studied the induction of protease activity by the laminin-derived peptide, SIKVAV, in cells (CAC2) derived from this neoplasm. Laminin α1 and matrix metalloproteinases (MMPs) 2 and 9 were immunolocalized in adenoid cystic carcinoma cells in vivo and in vitro. CAC2 cells cultured on SIKVAV showed a dose-dependent increase of MMP9 as detected by zymography and colocalization of α3 and α6 integrins. Small interfering RNA (siRNA) knockdown of integrin expression in CAC2 cells resulted in decreased adhesion to the peptide. SIKVAV affinity chromatography and immunoblot analysis showed that α3, α6, and β1 integrins were eluted from the SIKVAV column, which was confirmed by mass spectrometry and a solid-phase binding assay. Small interfering RNA experiments also showed that these integrins, through extracellular signal-regulated kinase (ERK) 1/2 signaling, regulate MMP secretion induced by SIKVAV in CAC2 cells. We propose that SIKVAV increases protease activity of a human salivary gland adenoid cystic carcinoma cell line through α3β1 and α6β1 integrins and the ERK 1/2 signaling pathway. PMID:17591960

  10. The influence of positive margins and nerve invasion in adenoid cystic carcinoma of the head and neck treated with surgery and radiation

    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

  12. Accuracy of methionine-PET in predicting the efficacy of heavy-particle therapy on primary adenoid cystic carcinomas of the head and neck

    We evaluated whether or not PET or PET/CT using L-methyl-[11C]-methionine (MET) can allow for the early prediction of local recurrence and metastasis, as well as the prognosis (disease-specific survival), in patients with adenoid cystic carcinoma of the head and neck treated by carbon ion beam radiotherapy. This was a retrospective cohort study of sixty-seven patients who underwent a MET-PET or PET/CT study prior to and one month after the completion of carbon ion radiotherapy (CIRT). The minimum follow-up period for survivors was 12 months. The MET accumulation of the tumor was evaluated using the semiquantitative tumor to normal tissue ratio (TNR). A univariate analysis was conducted using the log-rank method, and the Cox model was used in a multivariate survival regression analysis. The average TNR prior to and following treatment was 4.8 (±1.5) and 3.0 (±1.3), respectively, showing a significant decrease following treatment. In the univariate analysis, a high TNR prior to treatment (TNRpre) was a significant factor for predicting the occurrence of metastasis and the disease-specific survival. A high TNR following treatment (TNRpost) was a significant factor for predicting the development of local recurrence. The residual ratio of TNR changes (TNRratio) seemed to be less useful than the TNRpre. In the multivariate analysis, the TNRpost and tumor size were the factors found to significantly influence the risk of local recurrence. The TNRpre, TNRratio and tumor size were all significant factors influencing the occurrence of metastasis. Regarding the disease-specific survival, the TNRpre and age were the only factors with a significant influence on the outcome. The TNRpre was a factor that was significantly related to the occurrence of metastasis and the disease-specific survival after CIRT for adenoid cystic carcinoma of the head and neck. The TNRpost was a factor that was significantly related to the development of local recurrence. Thus, MET-PET or PET/CT can

    2012-01-01

    Objective: To explore the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell and Survivin gene expression in adenoid cystic carcinoma (ACC) of lacrimal gland. Methods:ACC-2 cell in human with ACC of lacrimal gland was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin gene expression was analyzed by RT-PCR and Western blotting. Results: EGB had inhibitory effect on the proliferation of ACC-2 cell with significant dose-effect relationship, and there was statistical difference when compared with the control group (P<0.01). The inhibitory concentration 50 % (IC50) is 88 mg/L. The flow cytometer test indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell was obviously increased (P<0.05 or P<0.01). EGB had certain inhibitory effect on Survivin gene expression of ACC-2 cell, and Survivin gene expression was decreased with the increasing of the EGB concentration (P<0.01). Conclusions:EGB can effectively inhibit Survivin gene expression of ACC-2 cell in human with ACC of lacrimal gland, induce the apoptosis of ACC-2 cell and inhibit tumor cell proliferation.

    This study investigates whether Wnt components play a role in carcinogenesis, or the invasion and metastasis of salivary glands, also referred to as adenoid cystic carcinoma (sAdCC). Several sAdCC cell lines with low invasive potential (ACC-2), high metastatic potential (ACC-M), and higher invasive potential (T-ACC-M) were examined to determine whether Wnt components correlate with tumors' invasive and metastatic behavior. Immunohistochemistry was performed in a sAdCC tissue array. ACC-M expressed higher levels of Wnt-1, beta-catenin and lower WIF-1 compared to ACC-2 (PWIF-1 compared to ACC-2 and ACC-M. Immuno-histochemistry showed up-regulation of Wnt-1 and down-regulation of WIF-1 in sAdCC compared with normal salivary glands. Beta-catenin was found in the cytoplasm and nuclei of sAdCC. Dislocation of E-cadherin in sAdCC was observed. These results suggest that sAdCC exhibits diverse expressions of Wnt components. It has an important relationship with the invasive phenotype of these cells. PMID:26405993

    Adenoid cystic carcinoma (ACC) is an exocrine gland tumor accounting for approximately 10%-15% of all epithelial salivary neoplasms and occurs most often in the parotid and submandibular glands. Metastatic pituitary tumors are rare, and there is only 1 previously reported case of parotid ACC metastatic to the pituitary. Magnetic resonance elastography (MRE) is a dynamic magnetic resonance imaging (MRI)-based technique that measures the propagation of mechanically induced shear waves through a particular tissue to determine stiffness and offers a method to evaluate tissue consistency. We present the case of a 72-year-old woman with a remote history of parotid gland ACC and subsequent lung metastases presented after a fall that resulted in facial trauma. A non-contrast head computed tomography scan revealed a sellar/suprasellar mass, and follow-up MRI revealed a well-defined, enhancing 3.8-cm lesion. MRE showed the tumor to be firm. The tumor was resected through a transsphenoidal approach and was consistent with the MRE findings. Pathology returned as metastatic ACC. We report the second case of ACC metastatic to pituitary and the first firm pituitary tumor found by MRE and discuss the potential diagnostic value of MRE in pituitary lesions. PMID:27018011

    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.

  18. Expression of beclin 1 in primary salivary adenoid cystic carcinoma and its relation to Bcl-2 and p53 and prognosis

    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).

  19. Treatment outcomes of particle radiotherapy using protons or carbon ions as a single-modality therapy for adenoid cystic carcinoma of the head and neck

    Background and purpose: The aim of this study was to retrospectively analyse the outcomes of cases of adenoid cystic carcinomas (ACCs) of the head and neck that were treated at a single institution with particle therapy consisting of either protons or carbon ions. Methods and materials: Between February 2002 and March 2012, 80 patients were treated with proton therapy (PT) or carbon ion therapy (CIT) alone. PT and CIT were employed in 40 (50%) patients each, and more than half of the patients received 65.0 GyE in 26 fractions (n = 47, 59%). Results: The median duration of follow-up was 38 months (range, 6–115 months). For all patients, the 5-year for overall survival (OS) rate, progression-free survival (PFS) rate, and local control (LC) rate were 63%, 39%, and 75%, respectively. No significant differences between PT and CIT were observed. The 5-year LC rates for T4 and inoperable cases were 66% and 68%, respectively. Twenty-one patients (26%) experienced grade 3 or greater late toxicities, including three patients who developed grade 5 bleeding from nasopharyngeal ulcers. Conclusions: Particle radiotherapy for ACC achieves favourable LC, and its efficacy in inoperable or T4 cases is promising. There were no significant differences between PT and CIT in terms of OS, PFS and LC

    The authors discuss the characteristics and the radiotherapy treatment procedures of cystic adenoid carcinomas, and more precisely the treatment of two of such cases of nasopharyngeal carcinomas. The first one had an incomplete resection surgery followed by curing radiotherapy: he has then been in local-regional control situation for 8 months. The second one had lung metastases, was treated chemotherapy and radiotherapy (decompressive treatment), and died six months after diagnosis. Radiotherapy is considered to be the treatment basis, whereas chemotherapy is a matter of controversy. Short communication

  1. c-Kit Expression is Rate-Limiting for Stem Cell Factor-Mediated Disease Progression in Adenoid Cystic Carcinoma of the Salivary Glands

    2014-10-01

    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.

    Adenoid cystic carcinoma (ACC) is an aggressive malignant neoplasm of the secretory glands. Conventional chemotherapy has poor effectiveness against metastatic ACC. Thus, a novel effective therapy is needed against metastatic ACC. A majority of ACCs (up to 94%) express c-kit. Imatinib is monoclonal antibody with specific activity against c-kit but has not been found to be effective in treating patients with ACC in which c-kit is overexpressed and activated. The NF-κB and mTOR pathways have been shown that ubiquitously and concurrently activated, indicating that the inhibition of these pathways may represent a novel treatment approach for patients with ACC. Curcumin has been shown to inhibit NF-κB and NF-κB-related pathways. 43-year-old patient was diagnosed ACC from submandibular salivary gland. After complete resection of tumor adjuvant radiotherapy was initiated. Seven years later multiple lung metastases were detected and ACC was confirmed by re-biopsy. First-line chemotherapy failed. NF-κB and c-kit were overexpressed in the metastatic specimens. Therefore, we treated the patient with metastatic chemoresistant ACC with imatinib 400mg/day and intravenous curcumin 225mg/m(2) twice a week plus oral bioavailable curcumin Arantal(®) 2×84mg/day. At 24 months, we observed near complete anatomic and complete metabolic response. To our knowledge, this is the first report of a patient with a c-kit-positive ACC that is successfully treated with the combination of imatinib and curcumin in an integrative approach. PMID:27515884

    Adenoid cystic carcinoma (AdCC) of the breast is an uncommon but distinct neoplasm composed of a dual cell population polarized around true glandular (luminal) spaces and pseudolumina. The aim of this study was to clarify whether various immunohistochemical markers (CK7, EMA, CD117, p63, calponin, CD10, S100, CK5/6, CK14, vimentin, and type IV collagen) can distinguish between the two cell types in classical AdCC (n = 14) and in collagenous spherulosis (n = 5). The sensitivity and specificity of these 11 markers to distinguish luminal from abluminal cells were evaluated using a curve created by plotting the true-positive rate (sensitivity) against the false-positive rate (1 - specificity) at threshold settings of 0, 10, 50, and 70 %. The most sensitive and specific markers for luminal cells in AdCC were CK7 and EMA; those for abluminal cells were type IV collagen, p63, and vimentin. CD10 and S100 did not act as abluminal markers in AdCC. CK5/6, one of the basal/myoepithelial markers, was expressed more frequently in luminal than in abluminal cells of AdCC. Thus, CK5/6 immunostaining resulted in a reverse expression pattern, analogous to what we recently documented in clear cells in mammary adenomyoepithelioma. In conclusion, compared with myoepithelial/abluminal cells of normal breast or collagenous spherulosis, the neoplastic abluminal cells of classical AdCC are characterized by enhanced vimentin and attenuated CD10 and S100. Furthermore, the luminal cells of AdCC show a unique aberrant staining pattern for CK5/6 that may aid in the differential diagnosis. PMID:27240462

  4. The T-box transcription factor Brachyury regulates epithelial–mesenchymal transition in association with cancer stem-like cells in adenoid cystic carcinoma cells

    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

    Full Text Available Context: Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from the salivary, lacrimal, or other exocrine glands. It is characteristically locally infiltrative in nature and has a tendency toward local recurrence, high propensity for perineural invasion, and prolonged clinical course. Aim: To analyze the presentation and natural history of cases of adenoid cystic tumors of salivary glands in our institution; and to compare with the existing literature. Design and Setting: Retrospective study at the Department of Radiotherapy. Materials and Methods: Data on 18 patients of ACC of the salivary glands treated between 2004 and 2008 were reviewed with respect to clinical presentation, stage, and histology. Results: There were 8 cases of major salivary gland tumors (47%, of which 2 were in the submandibular and 6 were involving the parotid. Ten patients (53% had minor salivary gland involvement. Two patients had metastasis at the time of presentation. All patients underwent surgery. Radiotherapy was delivered to 16 patients and chemotherapy to 6 patients (concurrent, n = 3 and adjuvant, n = 3 and no adjuvant therapy was given to 2 patients. All patients were alive at a median follow-up of 3 years. No patient developed local or distant failure during the study duration. Conclusion: ACC has locally aggressive behavior. Radiotherapy adjuvant to surgery improves local control in locally advanced disease. Longer follow-up is mandatory in view of incidence of late metastasis.

    PURPOSE:To investigate the expression of ErbB3 binding protein ebpl, E-cadherin, ICAM-1 and matrix metalloproteinase-9 (MMP-9) in salivary adenoid cystic carcinoma (SACC), and to explore their relationship with clinical pathological features. METHODS:Two-step immunohistochemical staining method was used to detect the expression of ebpl E-cadherin, ICAM-1 and MMP-9 in 33 cases with human SACC and 33 with para-cancerous normal tissues. All data were analyzed with SPSS17.0 software package. RESULTS:Positive expression rate of ebpl in SACC was 84.85%, lower than in normal salivary tissues (96.97%). Ebpl expression was significantly correlated to pathological pattern and clinical stage (P<0.05),but not correlated to gender and age. Positive expression rate of ebpl at Ⅰ- Ⅱ stage was higher than that of SACC at Ⅲ - Ⅳ stage; in regard to pathological typing, higher expression was found in adenoid tubular type than in solid type; the positive expression rate in patients with tumor metastasis was lower than in patients without metastasis (P<0.05). Expression of ebpl had a positive relationship with E-cadherin (r=0.851 ,P<0.01), while a negative relationship was found with MMP-9 (r=-0.364,P<0.05). CONCLUSIONS:Expression of ebpl may be associated with progression of SACC. Ebpl has important role in the generation and evolution of adenoid cystic carcinoma, and can be used as a useful indicator for clinical assessment of tumor biological behavior and prognosis in patients with adenoid cystic carcinoma.

    2015-01-01

    Introduction:Patients with nasopharyngeal carcinoma (NPC) sporadically develop abnormal adenoids. Nasopharyngeal adenoids are usually included in the gross tumor volume (GTV) but may have different therapeutic responses than tumor tissue. Therefore, distinguishing adenoids from tumor tissue may be required for precise and efficient chemoradiotherapy and radiotherapy. We characterized nasopharyngeal adenoids and investigated the therapeutic responses of NPC and nasopharyngeal adenoids using magnetic resonance imaging (MRI). Methods:MRI data from 40 NPC patients with a coexisting adenoid mass before and after treatment were analyzed. The features of the adenoid masses, including location, striped appearance, size, interface, symmetry/asymmetry, and cysts, were evaluated. Treatment response were scored according to the World Health Organization guidelines. Results:A striped appearance was observed in 36 cases before treatment and in all cases after treatment. In these 36 cases, the average GTVs including and excluding the uninvolved adenoids were 19.8 cm3 and 14.8 cm3, respectively. The average percentage change after excluding the uninvolved adenoids from the GTV was 31.0%. Stable disease in the adenoids was identified in 27 (96.4%) of 28 patients after neoadjuvant chemotherapy, while NPC clearly regressed. Partial adenoid responses were identified in 33 (82.5%) of 40 patients at 3 months after chemoradiotherapy or radiotherapy, whereas complete tumor responses were achieved in all patients. Six months after treatment, the adenoids continued to atrophy but did not disappear, and tumor recurrence was not found. Conclusions:Nasopharyngeal adenoids and carcinoma tissue in NPC patients can be distinguished by using MRI and have different responses to chemoradiotherapy and radiotherapy. These findings contribute to better delineating the GTV of NPC, based on which spatially optimized strategies can be developed to render precise and efficient chemoradiotherapy and

    Salivary gland-type lung carcinomas are uncommon neoplasms of the lung, the two most common being adenoid cystic carcinoma and mucoepidermoid carcinoma. Although they usually have an indolent behavior, adenoid cystic carcinomas can be more aggressive, with 5-year survival as low as 55%. Unfortunately, these tumors do not respond well to chemotherapy. In contrast to the most common subtypes of lung carcinomas, epidermal growth factor receptor studies have not been carried out in this group of ...

  15. Adding concurrent chemotherapy to postoperative radiotherapy improves locoregional control but Not overall survival in patients with salivary gland adenoid cystic carcinoma—a propensity score matched study

    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.

    Objective To investigate the effect of 5-aza-2'-deoxycytidine (5-Aza-CdR),a methylation inhibitor,on O6-methylguanine-DNA methyltransferase (MGMT) and human homo sapiens mutL homolog 1 (hMLH1) gene expression in salivary adenoid cystic carcinoma(SACC) cell line.Methods Methyl thiazolyl tetraxolium (MTT) assay was used to test the cytotoxicity of 5-Aza-CdR treatment at different concentrations.And then the mRNA expression of hMLH1 and MGMT was detected by reverse trancriptase polymerase chain reaction (RT-PCR) and real time PCR.Results The half maximal inhibitory concentration of a substance(IC50) value of 5-Aza-CdR in SACC-83 and SACC-LM cells was (11.816 ± 0.023) μmoL/L and (5.751 ± 0.049) μmol/L,respectively.RT-PCR and real time PCR showed that mRNA expression level of MGMT and hMLH1 in SACC cells increased after treated by 5-Aza-CdR (P < 0.01).Conclusions 5-Aza-CdR can change cells morphology and up-regulate mRNA expression of MGMT and hMLH1,which may be correlated with the reversion of hypermethylation status on these gene promoters in tumor cells.%目的 观察5-氮杂-2’-脱氧胞苷(5-aza-2-deoxycytidine,5-Aza-CdR)对体外培养人涎腺腺样囊性癌(salivary adenoid cystic carcinoma,SACC)细胞系细胞O6-甲基鸟嘌呤-DNA甲基转移酶(O6-methylguanine-DNA methyhransferase,MGMT)和人类mutL同源物1(homo sapiens mutL homolog 1,hMLH1)基因表达的影响,探讨DNA甲基转移酶抑制剂应用于SACC治疗的可行性及机制.方法 用不同浓度5-Aza-CdR分别处理体外培养SACC-83和SACC-LM细胞作为药物处理组,以药物处理浓度0 μmol/L为对照组.甲基噻唑基四唑法确定5-Aza-CdR的半数抑制浓度(half maximal inhibitory concentration of a substance,IC50);实时聚合酶链反应和反转录聚合酶链反应检测用药后细胞中MGMT和hMLH1 mRNA表达水平.结果 药物处理细胞24 h后细胞形态发生变化,并且随时间延长变化愈加显著.5-Aza-CdR对SACC-83和SACC-LM细胞的IC50

  18. Exclusive irradiation of cyst adenoid carcinomas: contribution of a dose complement in stereotactic mode

    The cyst adenoid carcinoma is a rare malignant tumor that reaches principally the salivary glands; It is characterized by a clinical aggressiveness, the presence of peri neural invasions, frequent local recurrences and a high rate of metastases dissemination at delayed distance. The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

    Full Text Available We report a case of multiple gastric carcinomas associated with Potter type III cystic disease of the liver, mesenterium and kidney. A 65-year-old man with chronic renal failure due to polycystic kidneys and under hemodialysis treatment 3 times a week for 2 years was admitted to our hospital because of anemia. He stated that his sister had suffered from polycystic kidney disease. Gastrointestinal fiberscopy showed two lesions in the lesser curvature in the lower portion of the stomach, and histopathological analysis of the gastric tumor biopsies revealed that one of the tumors was a papillary adenocarcinoma and the other a poorly differentiated adenocarcinoma. Helicobacter pylori infection was not detected in the stomach mucosa. Abdominal computed tomography scan revealed polycystic lesions in the liver, mesenterium and both kidneys. These imaging findings and family history suggested that the patient suffered from multiple gastric carcinomas associated with Potter type III cystic disease of the liver, mesenterium and kidney. Reports on the association of malignant neoplasm with Potter type III cystic disease are extremely rare. Especially, no case of the association of gastric carcinoma with Potter type III cystic disease of the liver and kidney has been described previously. This is a first report of the association of gastric carcinoma with Potter type III cystic disease. We also review reports of other malignant neoplasms associated with polycystic disease.

    tumor that contains a mixture of malignant cells with squamous and glandular differentiation. The literature points to the importance of making this diagnosis when the cellular components are still well differentiated in the sample, otherwise the tumor may be erroneously interpreted as squamous carcinoma or adenocarcinoma. This study describes an unusual presentation of a adenosquamous carcinoma in a 47 year old patient. After conflicting cytological diagnoses and a history of abnormal uterine bleeding caused by cervical endometriosis, the patient was subjected to radical hysterectomy and a final diagnosis was obtained. The tumor was diagnosed as adenosquamous carcinoma. In many aspects, however, it was similar to the adenoid basal carcinoma. Characteristic features of the adenoid basal carcinoma such as the presence of high-grade squamous intraepithelial lesion in the surface epithelium, squamous and glandular differentiation in the center of the neoplastic mass, and basaloid cells in deep areas of the tumor were observed. Therefore, the following elements usually absent from adenoid basal carcinoma were present in this case: atypia and mitotic figures in undifferentiated cells, squamous-mucinous intraepithelial lesion (SMILE in the superficial areas. Epidemiological and clinical data, such as patient age (47, race (white and presentation (a cervical mass, concurred to exclude the diagnosis of adenoid basal carcinoma. Other differential diagnoses include pure squamous carcinoma or adenocarcinoma, collision tumor, and endometrial adenocarcinoma with squamous differentiation invading the uterine cervix.

    Purpose To investigate the clinicopathologic features of cervical adenoid basal cell carcinoma. Methods Clinical and pathological data were analyzed in 12 cases of cervical adenoid basal cell carcinoma and the relevant literatures were reviewed. Results The age of 12 cases of with cervical adenoid basal cell cancer patients ranged from 36~70 years ( mean:53. 3 years) , with a medi-an age of 51. 5 years. Amongst 12 patients who contained no gross definite lesion, 5 patients (41. 7%) had the symptoms of vaginal bleeding. 8 cases of patients underwent hysterectomy, while the other four received cervical conization. Cervical intraepithelial neopla-sia ( CIN) lesions were observed in all 12 cases. The tumor cells were small and uniform, with dark oval nuclei without conspicuous nucleoli and scanty cytoplasm. Tumor infiltrated into the stroma in nests and cords. Glandular differentiation within tumor nests were seen in 12 cases, including two cases of squamous cell differentiation accompanied by partial and minor interstitial edema. Peripheral palisading cells around tumor nests were also found. The infiltrating depth of tumor ranged from 0. 5~10 mm with the average 4. 12 mm. Cancer embolis were available in 2 cases with no lymph node metastasis. 10 cases followed up for 3~78 months with no recur-rence and metastasis, but 2 cases were lost. Conclusion Adenoid basal cell carcinoma is a rare uterine cervical tumor found in post-menopausal women, which are often accompanied with CIN. This tumor has a favorable prognosis and should be clearly separated from adenoid cystic carcinoma and other tumors which also have infiltrative growth pattern.%目的:探讨子宫颈腺样基底细胞癌的临床病理学特征。方法回顾性分析12例子宫颈腺样基底细胞癌患者的临床病理资料、组织学特征及免疫表型,并复习相关文献。结果12例子宫颈腺样基底细胞癌患者年龄36~70岁,平均53.3岁。5例(41.7%)有阴道出血症状,12例中8

    Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports. PMID:24009635

    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.

  19. Hepatocellular carcinoma complicating cystic fibrosis related liver disease.

    O'Donnell, D H

    2012-02-01

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

  20. Results of fast neutron therapy of adenoid cystic carcinoma of the salivary glands

    72 consecutive patients with ACC were treated with fast neutrons, 66 after surgery, 6 for primarily unresectable disease, 43/66 for macroscopic residual disease, 23/66 for unresectable recurrent disease. 45/72 tumors were localized in the minor, 27 in the major salivary glands. T-stage was in 13 pts T2, in 33 T3, in 26 T4; positive nodes were in 10 pts. M+ in 15 pts. Mean tumor volume was 89 cm3. Neutron therapy was 15.03 Gy in 3 weeks with 1.67 Gy per fraction three times per week. Individual computer assisted treatment planning was performed based on CT and/or MRI, using bolus material if necessary. Target volume was the macroscopic tumor volume with a generous safety margin. Results: Complete response was achieved in 28 pts, partial response in 35 pts. Local control was observed in 73.4% after a mean observation period of 36 months. Overall and recurrence free survival was 85%/81% at two years, and 58%/53% at 5 years (Kaplan-Meier). In univariate analysis tumor volume (> 100 cm3), distant metastases, histologic subtype (solid) and neutron dose (<15 Gy) turned out to be significant parameters for predicting outcome, in multivariate analysis tumor volume and histologic subtype remained the only significant parameters. Acute morbidity was grade III/IV (EORTC/RTOG) in 6% for skin (desquamation), in 4% for mucosa (ulceration), late morbidity (grade III/IV) in one patient with local temporal brain necrosis. (orig.)

    Although local recurrence of renal cell carcinoma after laparoscopic radical nephrectomy is sometimes reported, cystic local recurrence of renal cell carcinoma has rarely been reported. We report the case of a 59-year-old man with hemodialysis who developed cystic local recurrence of renal cell carcinoma accompanied by acquired cystic disease of the kidney in the retroperitoneal space after laparoscopic radical nephrectomy. A cystic tumor of 5.1 cm in diameter occurred in the left retroperitoneal space 15 months after left laparoscopic radical nephrectomy, and enlarged to 7.2 cm in diameter with enhanced mass along the wall of the cyst 36 months after surgery. The cystic tumor was removed and showed local recurrence of renal cell carcinoma on pathological examination. PMID:23909823

  2. Radiation therapy for carcinoma of the major salivary glands

    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 60Co 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.)

The treatment is surgery with a postoperative adjuvant radiotherapy. for the patients suffering of inoperable tumors, the exclusive radiotherapy gives bad results with tests of use of heavy particles. The place of a hypo fractionated treatment on a stereotactic mode has not been evaluated, especially in dose complement after three dimensional irradiation. The purpose was to answer the following question if the Cyberknife was useful to deliver a complement of hypo fractionated stereotactic dose for the inoperable head and neck tumors. The limited number of patients does not allow a definitive conclusion. however, this therapy option seems interesting for the inoperable tumors subject to the management of the toxicity induced by the treatment. The evaluation of the irradiation volumes remains the critical element for the feasibility of this kind of protocol. (N.C.)

  10. Safety of Chemotherapeutic Infusion or Chemoembolization for Hepatocellular Carcinoma Supplied Exclusively by the Cystic Artery

    Purpose: This study was designed to evaluate the safety of chemotherapeutic infusion or chemoembolization by way of the cystic artery in patients with hepatocellular carcinoma (HCC) supplied exclusively by the cystic artery. Methods: Between Jan 2002 and Dec 2011, we performed chemotherapeutic infusion or chemoembolization using iodized oil for the treatment of 27 patients with HCC supplied exclusively by the cystic artery. Computed tomography (CT) scans, digital subtraction angiograms, and medical records were retrospectively reviewed by consensus. Results: The cystic artery originated from the main right hepatic artery in 24 (89 %) patients, from the right anterior hepatic artery in 2 (7 %) patients, and from the left hepatic artery in 1 (4 %) patient. Selective catheterization of the cystic artery was achieved in all patients. Superselection of tumor-feeding vessels from the cystic artery was achieved in 7 patients (26 %). Chemotherapeutic infusion was performed in 18 patients (67 %), and chemoembolization was performed in 9 patients (33 %). There were no major complications and only 2 minor complications, including vasovagal syncope and nausea with vomiting. Individual tumor response supplied exclusively by the cystic artery at the follow-up enhanced CT scan were complete response (n = 16), partial response (n = 3), and stable disease (n = 8). Conclusion: HCC supplied exclusively by the cystic artery can be safely treated without severe complications by chemotherapeutic infusion or chemoembolization using iodized oil through the cystic artery

    Minor salivary gland carcinoma is a rare and heterogeneous type of cancer. Molecular prognostic and predictive markers are sparse. The aim of this study was to identify new prognostic and predictive markers in minor salivary gland carcinoma. 50 tissue samples of carcinomas of the minor salivary glands (adenoid cystic carcinoma n = 23, mucoepidermoid carcinoma n = 12, adenocarcinoma n = 10, carcinoma ex pleomorphic adenoma n = 2, salivary duct carcinoma n = 1, clear cell carcinoma n = 1, basal cell carcinoma n = 1) were immunohistochemically stained for β-catenin, cyclin D1 and PIN1. Expression patterns were analyzed and correlated to clinical outcome of 37 patients with complete clinical data. High expression of membranous β-catenin was linked to significantly better overall survival in patients with adenoid cystic carcinoma (log rank test, χ (2) = 13.3, p = .00397, Bonferroni corrected p = .024). PIN1 and cyclin D1 did not show any significant correlation to patients' clinical outcome. Expression of β-catenin in adenoid cystic carcinoma of the minor salivary glands significantly correlates with better overall survival. Hence, evaluation of β-catenin might serve as a clinical prognostic marker. PMID:25801951

  2. Conventional papillary thyroid carcinoma: effects of cystic changes visible on ultrasonography on disease prognosis

    To investigate the characteristics of papillary thyroid carcinoma (PTC) with cystic changes visible on ultrasonography (US). This study included 553 PTCs in 553 patients between January 2003 and August 2004. One radiologist with 10 years of experience in thyroid imaging retrospectively reviewed the preoperative US images. Two different groups were formed according to two different reference points (group 1, 25%; group 2, 50%) of the cystic component. Patients between the groups were compared according to their clinicopathologic characteristics. Disease-free survival (DFS) was estimated. Cox's multivariate proportional hazards regression model was used to identify the effect of variable factors on the recurrence risk. Fifty-six patients (10.1%) were confirmed to have tumor recurrence within the follow-up period. Thirty-five patients had regional metastasis, one had distant metastasis, eight had multiple site metastases, and 12 had biochemical recurrence. PTC patients with a ≤ 50% or PTC patients with a ≤ 25% cystic component did not have a statistically significant longer DFS than those with a >50% (hazard ratio [HR], 1.118; 95% confidence interval [CI], 0.255 to 4.910; P=0.883) or those with a >25% cystic component (HR, 0.569; 95% CI, 0.164 to 1.976; P=0.375), respectively. Moreover, independent predictors of recurrence were pathologic size, male gender, and lymph node metastasis, not a >50% or >25% cystic component. The proportion of the cystic component in PTCs did not affect DFS.

  6. Acquired cystic disease and renal cell carcinoma in hemodialysis patients: A case report on three patients

    Mijušković Mirjana

    2015-01-01

    Full Text Available Introduction. Renal cell carcinoma (RCC is derived from renal tubular epithelial cells and represents approximately 3.8% of all malignancies in adults. The incidence of renal cell carcinoma has been growing steadily and ranging from 0.6 to 14.7 for every 100,000 inhabitants. Patients with end-stage renal disease and acquired cystic kidney disease are at increased risk of developing RCC while undergoing dialysis treatment or after renal transplantation. Case report. We presented 3 patients undergoing hemodialysis, with acquired cystic kidney disease accompanied by the development of RCC. In all the patients tumor was asymptomatic and discovered through ultrasound screening in 2 patients and in 1 of the patients by post-surgery pathohistological analysis of the tissue of the kidney excised using nephrectomy. All the three patients had organ-limited disease at the time of the diagnosis and they did not require additional therapy after surgical treatment. During the follow- up after nephrectomy from 6 months to 7 years, local recurrence or metastasis of RCC were not diagnosed. Conclusion. Acquired cystic kidney disease represents a predisposing factor for the development of renal cell carcinoma in dialysis patients and requires regular ultrasound examinations of the abdomen aimed at early diagnosis of malignancies. Prognosis for patients with endstage renal disease and RCC is mostly good because these tumors are usually of indolent course.

  8. Colloid Carcinoma of the Extrahepatic Biliary Tract with Metastatic Lymphadenopathy Mimicking Cystic Neoplasm: A Case Report

    The patient is a previously healthy 52-year-old woman who presented with dyspepsia for two months. Multiple imaging modalities including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) showed diffuse bile duct dilatation with an obstructive lesion of the distal extrahepatic biliary duct (EHD) as well as two masses in the peripancreatic area. The peripancreatic masses appeared cystic with posterior acoustic enhancement on ultrasound, low density on CT imaging, and high signal intensity on T2-weighted MRI. The lesion in the distal EHD exhibited similar characteristics on CT and MRI. A Whipple procedure was performed and histological specimens showed malignant cells with large mucin pools that was consistent with a diagnosis of colloid carcinoma of the EHD with metastatic lymphadenopathies. Colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. Because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. We report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with characteristic imaging findings reflecting abundant intratumoral mucin pools

    To report on the safety and efficacy of superselective transcatheter arterial chemoembolization(TACE) of tumor feeding branches originating from the cystic artery for the treatment of hepatocellular carcinoma(HCC). From, May 1955 to, September 1999, eleven HCC patients aged between 38 and 82 (mean, 57.4) years with tumor-feeding branches originating from the cystic artery underwent TACE. In eight, for whom superselection of these branches was possible, TACE was done with the use of Gelform and a mixture of Lipiodol and cisplatin, while for three, for whom superselection was impossible, a mixture of Lipiodol and cisplatin only was used. Immediately after TACE, remnant tumor staining was angiographically evaluated, and tumor response was determined by follow-up CT at one month. After procedure, the development of cholecystitis was clinically. Post-FACE angiography showed remnant tumor staining in one patients who underwent embolization with Gelform and the mixture fo Lipiodol and cisplatin, and in one for whom the mix ture of Lipodol and cisplationly was used. Among the eight for whom Gelfoam and the mixture of Lipiodol and cisplatin was used, one-month follow up CT showed compact Lipiodol uptake in five, partial Lipiodol uptake in three, no change in tumor size in six, increased tumor size in one, and decreased tumor size in one. Among the three for whom the mixture of Lipiodol and cisplatin only was used,one-month follow-up CT showed neither Lipiodol uptake nor change in tumor size in one patient, partial Lipiodol uptake and increased tumor size in one, and compact Lipiodol uptake and decreased tumor size in one. Cholecystitis developed in only one patient who underwent embolization with Gelfoam and the mixture of Lipiodol and cisplatin, but was cured by conservative treatment. Superselective TACE of tumor feeding branches originating from the cystic artery seems to be a safe and effective method for the treatment of hepatocellular carcinoma.

    The initial and follow-up CT and MRI images of ten patients with hepatic metastases from ovarian tumors were retrospectively analyzed to establish their features and sequential changes in appearance. Ten patients with hepatic metastasis from ovarian tumors received initial and follow-up CT and MRI examinations. Six patients were followed up every two to three weeks before surgical tumor resection. Both CT and MR images were analyzed by two radiologists. A total of fourteen lesions were detected by CT and MRI in 10 patients. All 14 lesions were demonstrated as areas of marked hyperintensity on T2-weighted MRI. Eleven cyst-like tumors were demonstrated as round or oval low density lesions on CT and as areas of hypointensity on T1-weighted imaging. Three lesions were shown as solid masses with slightly low attenuation at the initial CT examination and slightly low or iso-intensity areas on T1-weighted imaging, and these lesions showed early peripheral globular enhancement and delayed enhancement on contrast-enhanced CT and MR imaging. Cystic formation was observed two to three weeks later after initial study in all the 3 solid lesions. Rapid subcapsular effusion, which showed obvious enhancement on delayed Gd-DTPA enhanced MR imaging, was observed in two patients. The hepatic metastatic tumor from cystic ovarian carcinoma may manifest as a well-defined cystic lesion or as a solid mass, and the solid mass shows delayed enhancement on contrast-enhanced CT and MR imaging. Furthermore, rapid cystic formation and rapid subcapsular extension is frequently seen. (author)

    Renal oncocytoma (RO) may present with a tubulocystic growth in 3% to 7% of cases, and in such cases its morphology may significantly overlap with tubulocystic renal cell carcinoma (TCRCC). We compared the morphologic and immunohistochemical characteristics of these tumors, aiming to clarify the differential diagnostic criteria, which facilitate the discrimination of RO from TCRCC. Twenty-four cystic ROs and 15 TCRCCs were selected and analyzed for: architectural growth patterns, stromal features, cytomorphology, ISUP nucleolar grade, necrosis, and mitotic activity. Immunohistochemical panel included various cytokeratins (AE1-AE3, OSCAR, CAM5.2, CK7), vimentin, CD10, CD117, AMACR, CA-IX, antimitochondrial antigen (MIA), EMA, and Ki-67. The presence of at least focal solid growth and islands of tumor cells interspersed with loose stroma, lower ISUP nucleolar grade, absence of necrosis, and absence of mitotic figures were strongly suggestive of a cystic RO. In contrast, the absence of solid and island growth patterns and presence of more compact, fibrous stroma, accompanied by higher ISUP nucleolar grade, focal necrosis, and mitotic figures were all associated with TCRCC. TCRCC marked more frequently for vimentin, CD10, AMACR, and CK7 and had a higher proliferative index by Ki-67 (>15%). CD117 was negative in 14/15 cases. One case was weakly CD117 reactive with cytoplasmic positivity. All cystic RO cases were strongly positive for CD117. The remaining markers (AE1-AE3, CAM5.2, OSCAR, CA-IX, MIA, EMA) were of limited utility. Presence of tumor cell islands and solid growth areas and the type of stroma may be major morphologic criteria in differentiating cystic RO from TCRCC. In difficult cases, or when a limited tissue precludes full morphologic assessment, immunohistochemical pattern of vimentin, CD10, CD117, AMACR, CK7, and Ki-67 could help in establishing the correct diagnosis.

  13. Differential expression of topoisomerase IIα protein in salivary gland carcinomas: histogenetic and prognostic implications

    Salivary gland carcinomas are relatively uncommon heterogeneous malignancies characterized by locoregional invasion and distant metastasis. Topoisomerase IIα (topoIIα), located at chromosome 17q21-22, is considered a major mediator of cell proliferation and DNA replication. The purpose of this study was to evaluate the expression of topoIIα in various types of salivary gland tumors and its biological significance. The protein expression of topoIIα was evaluated immunohistochemically in formalin-fixed, paraffin-embedded tissue from 54 salivary gland carcinomas and 20 benign tumors (10 pleomorphic adenomas and 10 Warthin's tumors). The primary salivary gland carcinoma specimens consisted of 17 adenoid cystic carcinomas, 7 adenocarcinomas not otherwise specified, 7 mucoepidermoid carcinomas, 6 salivary duct carcinomas, 3 acinic cell carcinomas, 3 carcinomas ex pleomorphic adenomas, 3 epithelial-myoepithelial carcinomas, 2 carcinosarcomas, 2 lymphoepithelial carcinomas, 2 myoepithelial carcinomas, 1 oncocytic carcinoma, and 1 squamous cell carcinoma. The associations between clinicopathological factors and outcome were analyzed. Of the 54 primary salivary gland carcinomas, 38 (70%) showed positive expression (≥10%) of topoIIα protein, and 16 carcinomas (30%) and all benign tumors were negative (p < 0.001). Expression of topoIIα was more frequently observed in salivary duct carcinoma, carcinoma ex pleomorphic adenoma, adenocarcinoma, and adenoid cystic carcinoma, solid type, and it was associated with advanced stage and shortened survival. The results of the present study suggest that topoIIα expression is associated with histologically aggressive subtypes and shortened survival. Furthermore, it may provide useful prognostic information and suggests the potential efficacy of topoIIα-targeting therapy in patients with salivary gland carcinoma

    Spindle cell carcinoma of the breast is a rare tumor. hTis tumor can proliferate rapidly and cause cystic changes because of internal tissue necrosis. We evaluated a 54-year-old woman with right breast lump. Mammography showed a category four mass with a diameter of 2.5 cm. Ultrasonography (US) revealed a complex cystic lesion, and ifne-needle aspiration (FNA) cytology demonstrated bloody fluid and malignant cells. Partial breast resection and sentinel lymph node biopsy were performed. Immunohistology revealed spindle cells with positive results for cytokeratin (AE1/AE3) and vimentin, partially positive results for s-100, and negative results for desmin and α-actin. The pathological stage was IIA, and biochemical characterization showed that the tumor was triple negative. Six courses of FEC-100 chemotherapy (5-fluorouracil 500 mg/m2, epirubicin 100 mg/m2, and cyclophosphamide 500 mg/m2) were administered. Radiotherapy was performed. hTis case is discussed with reference to the literature.

    Acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) is a recently established entity. In this article, we introduce the general view of this new entity. Macroscopically, the disease exclusively occurs in ACD and may arise as a dominant mass or non-dominant masses. Histologically, the tumor is characterized by a microcystic pattern, neoplastic cells with an eosinophilic or oncocytic cytoplasm and frequent intratumoral oxalate crystal deposition. Prominent nucleoli of tumor cells are often observed. Immunohistochemically, neoplastic cells are generally positive for AMACR but negative for cytokeratin 7. Ultrastructurally, neoplastic cells contain abundant mitochondria in the cytoplasm. Genetically, the gain of chromosomes 3, 7, 17 and abnormality of the sex chromosome were frequently observed in several studies. In conclusion, ACD-associated RCC may be widely recognized as a distinct entity in the near future because this tumor is morphologically and genetically different from other renal tumor entities that have been previously established.

    2011-12-01

    Acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) has been recently identified. However, there are only a few genetic studies to date. In this article, we performed an immunohistochemical and fluorescence in situ hybridization (FISH) study for six cases including one case with sarcomatoid change. As a result, we observed frequent immunohistochemical expression of AMACR. FISH of chromosome 3 showed trisomy for three cases, monosomy for two cases, and disomy for one case. Additionally, FISH of chromosome 16 showed trisomy for three cases, monosomy for two cases, and both trisomy and monosomy for one case. Furthermore, both the carcinomatous area and the sarcomatoid area of one ACD-associated RCC with sarcomatoid change revealed monosomy of chromosomes 3, 9, and 16 but showed disomy of chromosome 14. In conclusion, the numerical abnormalities of chromosomes 3 and 16, irrespective of gain or loss, may be characteristic of ACD-associated RCC. PMID:22179186

    Oncogenesis of anaplastic carcinoma of the pancreas is a subject of controversy, because it shows sarcomatous nature with extremely poor prognosis. We herein report an unusual case of anaplastic carcinoma occurring with a recurrent mucinous cystic neoplasm in a 38-year-old female. A 10-cm retroperitoneal cystic mass was pointed out in the first pregnancy and a probable diagnosis of mucinous cystic neoplasm was made in October 2000. She refused surgery first and delivered her baby uneventfully. During her second pregnancy in 2002, however, she presented hematemesis and underwent urgent distal pancreatectomy, splenectomy and partial resection of the gastric wall where the tumor perforated. A diagnosis of borderline-type mucinous cystic neoplasm with ovarian-like stroma was made. Nine months later, CT visualized a recurrent cystic tumor near the pancreatic stump, which was subsequently resected. Pathology revealed that the tumor was composed of two different components of borderline-type mucinous cystic neoplasm and anaplastic carcinoma. The latter was intensely positive for vimentin, CD68, p53 and focally for cytokeratin, suggesting both sarcomatous and carcinomatous differentiation. She survived four years after the second surgery without tumor recurrence. Although the origin of anaplastic carcinoma has not been determined yet, it should be remembered that anaplastic carcinoma can occur in association with mucinous cystic neoplasm of more benign histology.

    Acquired cystic disease-associated renal cell carcinoma (ACD-RCC) is a subtype of renal cell carcinoma (RCC) with unique morphologic features found exclusively in the background of end-stage renal disease. We analyzed the clinicopathologic features and immumoreactive profiles of 12 cases of ACD-RCC to further characterize this recently recognized entity. Review of histologic slides was performed in conjunction with immunohistochemical staining directed to the contemporary diagnostic antibodies and the putative target therapy-related markers. Histologically, the tumors showed characteristic inter-or intracellular microlumens and eosinophilic tumor cells. Intratumoral hemosiderin deposition and degenerating foamy tumor cells were consistent findings which were not previously described. Immunohistochemically, all the tumors were positive for alpha-methylacyl-CoA-racemase, CD10, pan-cytokeratin, PTEN (phosphatase and tensin homolog deleted on chromosome 10) and c-met, while negative for carbonic anhydrase-9, CD57, CD68, c-kit, pax-2, platelet-derived growth factor receptor (PDGFR)-α or vascular endothelial growth factor receptor (VEGFR)-2. Heterogenous staining was found for CK7 and kidney-specific cadherin. Positive reaction to c-met suggests its utility as a plausible therapeutic target in ACD-RCC. Thus, we present the unique morphologic and immunopathologic features of ACD-RCC, which may be helpful in both diagnostic and therapeutic aspects. PMID:23471757

    Most cases of cystic squamous cell carcinoma (SCC) metastases in the upper neck are associated with an oropharyngeal primary, namely human papillomavirus (HPV)-associated SCC arising in the palatine or lingual tonsil. A retrospective study was performed on 22 patients who presented with cystic head and neck SCC metastases. The purpose of the study was to find out whether histological characteristics, p16 protein expression, HPV and Epstein-Barr virus (EBV) status could be useful in predicting the localization of the primary tumor. The primary site was identified in 20 of 22 patients and included the oropharynx in 14 patients (63.6%), the nasopharynx in 3 patients (13.6%), the lungs in 2 cases (9%), and the skin of the auricle in one case (4.5%). No primary was found in two patients (9%). Sixteen of 17 cases (94.1%) originating in Waldayer's ring (oropharynx and nasopharynx), and both cases with an unknown primary showed morphology of non-keratinizing SCC or non-keratinizing SCC with maturation. All tumors with oropharyngeal primary and both cases with unknown primary showed diffuse p16 staining and presence of HPV DNA. All three cystic metastases of nasopharyngeal carcinoma were EBV-positive and p16/HPV-negative. In contrast, cutaneous and pulmonary metastases showed morphology of a well differentiated keratinizing SCC and poorly differentiated keratinizing SCC, respectively, and were HPV/EBV-negative. We confirmed that cystic SCC lymph node metastases of the head and neck region are strongly associated with the occult primary localized in the oropharynx. The oropharyngeal origin should always be corroborated by p16 immunohistochemistry and HPV-specific testing because SCC arising in other sites, such as nasopharynx, skin or lungs may manifest with cystic neck metastases as well. Addition of EBV testing in p16/HPV-negative cases can disclose the nasopharyngeal origin of the cystic neck metastases in a subset of cases. PMID:27013059

    Acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) is a recently described entity. To the best of our knowledge, there are no reports of ACD-associated RCC with sarcomatoid and rhabdoid changes. In this article, we present the first case of such a tumor. A 56-year-old Japanese man has received long-term hemodialysis and had a history of right renal cancer. Following the discovery of metastatic cancer in the thoracic wall, detailed imaging studies revealed a mass in the left kidney. The histologic examination of the left renal tumor showed ACD-associated RCC with sarcomatoid change and rhabdoid features. Immunohistochemically, intracytoplasmic globular inclusions in rhabdoid cells were positive for vimentin and cytokeratin CAM5.2. The G-band karyotype showed the following changes: 46, X, +X. -Y[1]/43, idem, add(2)(q31), -6, -9, -14, -15, +16, -22, +mar1[6]/46, XY[2]/abnormal cell[11]. In conclusion, pathologists and urologists should be aware that rhabdoid features may occur in ACD-associated RCC and that the loss of chromosomes 9 and 14 may occur during the process of sarcomatoid change in ACD-associated RCC.

    Pediatric nasopharyngeal carcinoma (NPC) is rare and usually poorly differentiated. We report a 14-year-old boy with NPC with metastases to liver, spleen, lymph nodes and bone marrow. The liver metastases closely resembled benign cystic liver disease on imaging; however, they showed intense uptake similar to other metastatic sites on positron emission tomography (PET) scan. A liver biopsy could not be performed on the boy. The boy responded clinically to platinum-based chemotherapy, and all the baseline PET-positive lesions became negative. This case highlights the rarity of splenic and cystic liver metastases in pediatric NPC and demonstrates the potential use of PET/CT in diagnosis, staging and response assessment in metastatic pediatric NPC.

  3. Patterns of nodal relapse after surgery and postoperative radiation therapy for carcinomas of the major and minor salivary glands: What is the role of elective neck irradiation?

    Purpose: To evaluate the incidence of nodal relapses from carcinomas of the salivary glands among patients with clinically negative necks in an attempt to determine the potential utility of elective neck irradiation (ENI). Methods and Materials: Between 1960 and 2004, 251 patients with clinically N0 carcinomas of the salivary glands were treated with surgery and postoperative radiation therapy. None of the patients had undergone previous neck dissection. Histology was: adenoid cystic (84 patients), mucoepidermoid (60 patients), adenocarcinoma (58 patients), acinic cell (21 patients), undifferentiated (11 patients), carcinoma ex pleomorphic adenoma (7 patients), squamous cell (7 patients), and salivary duct carcinoma (3 patients); 131 patients (52%) had ENI. Median follow-up was 62 months (range, 3-267 months). Results: The 5- and 10-year actuarial estimates of nodal relapse were 11% and 13%, respectively. The 10-year actuarial rates of nodal failure were 7%, 5%, 12%, and 16%, for patients with T1, T2, T3, and T4 disease, respectively (p = 0.11). The use of ENI reduced the 10-year nodal failure rate from 26% to 0% (p = 0.0001). The highest crude rates of nodal relapse among those treated without ENI were found in patients with squamous cell carcinoma (67%), undifferentiated carcinoma (50%), adenocarcinoma (34%), and mucoepidermoid carcinoma (29%). There were no nodal failures observed among patients with adenoid cystic or acinic cell histology. Conclusion: ENI effectively prevents nodal relapses and should be used for select patients at high risk for regional failure

  4. Pulmonary Pleomorphic Carcinoma Detected as a Result of Pneumothorax and the Subsequent Occurrence of Multiple Cystic Metastases

    Hideaki Yamakawa

    2014-01-01

    Full Text Available A 39-year-old man was admitted for spontaneous pneumothorax. He underwent pulmonary resection to correct the lesion causing the air leakage, and a pathological diagnosis of pulmonary pleomorphic carcinoma was made because we thought that the pneumothorax developed due to the direct rupture of necrotic neoplastic tissue into the pleural cavity. After the operation, the patient received chemotherapy, during which multiple cystic metastases gradually developed in the lung that caused repeated occurrences of pneumothorax. Clinicians must be careful to recognize that pneumothorax can also be a complication of primary and various metastatic pulmonary malignancies.

  5. Resection and Reconstruction of Maxillary Class IIIc Defect in a Case of Adenoid Cystic Carcinoma: Cost-Sensitive Technique without Microvascular Grafts

    Dwarkadas Adwani

    2013-01-01

    Full Text Available ACC is a rare malignant tumor that affects most commonly the major and minor salivary glands and rarely the paranasal sinuses, lacrimal gland, larynx, ear, vulva, and so forth. The maxillary sinus when affected is considered having a poor prognosis due to delayed diagnosis and delayed treatment credited to its slow spread, late symptoms, and complex anatomy which hampers surgical resection. The expressions of tumor markers too have a significant role in determining the prognosis. The treatment of choice consists of wide radical resection of the tumor followed by radiotherapy. Rehabilitation options in cases with huge maxillary defects still need further exploration.

    2016-05-01

    We report a rare case of synchronous clear cell renal cell carcinoma and multilocular cystic renal cell neoplasia of low malignant potential in the same kidney. The tumors were seen incidentally in a 45-year-old man. Pathologic study revealed that the former tumor was nucleolar grade 2, and the multilocular cystic renal cell neoplasia of low malignant potential was nucleolar grade 1. At immunohistochemistry, the clear cells in both tumors were positive for CD10 and CA IX. Interestingly, these uncommon synchronous tumors showed a different KRAS/NRAS mutation analysis that was characterized by KRAS mutation at codon p.G12C in the clear cell renal cell carcinoma, while this mutation was not present in the case of multilocular cystic renal cell neoplasia of low malignant potential. NRAS mutation was not seen in any of the tumors. PMID:26874573

  7. Renal-cell carcinomas in end-stage kidneys: a clinicopathological study with emphasis on clear-cell papillary renal-cell carcinoma and acquired cystic kidney disease-associated carcinoma.

    Bhatnagar, Ramneesh; Alexiev, Borislav A

    2012-02-01

    Clear-cell papillary renal-cell carcinoma (CCPC) and acquired cystic kidney disease-associated carcinoma (ACDAC) are neoplasms with distinct morphological characteristics that behave less aggressively than conventional renal-cell carcinomas. End-stage kidney specimens from 61 patients (47 males and 14 females) with 109 renal-cell carcinomas were selected. Papillary renal-cell carcinoma was the most common malignancy (61/109, 56%), followed by CCPC (20/109, 18%). The CCPC showed a papillary or tubular/solid architecture, clear cytoplasm, low nuclear grade, and a distinct immunohistochemical profile (RCC-, vimentin+, CK7+, p504S-). ACDAC displayed a variety of architectural patterns, eosinophilic cytoplasm, high nuclear grade, intratumoral calcium oxalate deposits, and an immunohistochemical profile similar to type 2 papillary renal-cell carcinoma (RCC+, vimentin+, CK7-/+, p504S+). Less than 5% (3/69) of pathologically staged renal-cell carcinomas in end-stage kidneys presented with lymphogenous and/or hematogenous metastases. PMID:21791489

  8. Myoepithelial Carcinoma of the Nasopharynx: Report of a Rare Case and a Review of the Literature.

    Soon, Gwyneth; Petersson, Fredrik

    2015-12-01

    Salivary gland carcinomas are very rare in the nasopharynx, with the most frequent histologic types being adenoid cystic carcinoma, mucoepidermoid carcinoma and adenocarcinoma, not otherwise specified. Myoepithelial carcinoma (MECA) is a rare tumor of the salivary glands, and there are only three previously reported cases of nasopharyngeal MECA. The case presented is the fourth reported case of MECA in the nasopharynx. Due to the morphologic heterogeneity of MECA, immunohistochemistry is indispensable in ascertaining the diagnosis. MECA is a locally aggressive tumor, but the long-term prognosis of this tumor in the nasopharynx remains uncertain. In our case the tumor was unresectable and the patient was given chemo-radiotherapy. Despite this, residual tumor was seen on nasoscopy 5 months after initial diagnosis and was documented on a re-biopsy which displayed the same histomorphologic features as the original tumor.

  12. Malignant Transformation of a Mature Cystic Ovarian Teratoma into Thyroid Carcinoma, Mucinous Adenocarcinoma, and Strumal Carcinoid: A Case Report and Literature Review

    Hilary D. Hinshaw

    2012-01-01

    Full Text Available Malignant transformation of a mature cystic teratoma (MCT is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a, mucinous adenocarcinoma (b, and strumal carcinoid tumor (c—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

    Clear cell papillary renal cell carcinoma (RCC) is a recently established disease entity. However, there are few reports on genetic study of this entity. We report such a case with focus on genetic study. A 57-year-old Japanese man was found to have 3 renal tumors. Histologically, two tumors showed findings of clear cell RCC; and the other tumor showed findings of clear cell papillary RCC that was characterized by papillary growth pattern of neoplastic cells in cystic space with purely clear cell cytology. Immunohistochemically, tumor cells of clear cell papillary RCC were diffusely positive for PAX2 and cytokeratin 7, but negative for CD10, RCC Ma, and AMACR. In fluorescence in situ hybridization study for one clear cell papillary RCC, we detected polysomy for chromosome 7 and monosomy for chromosomes 17, 16, and 20. In addition, we detected mutation of VHL gene in clear cell RCC, but found no VHL gene mutation in clear cell papillary RCC. Finally, our results provide further evidence that clear cell papillary RCC may be both morphologically and genetically distinct entity from clear cell RCC and papillary RCC. PMID:20952286

  16. Carcinomas of the nasal cavity

    Between 1969-1985, 45 patients with carcinomas of the nasal cavity proper received curative treatment. Of these, 30 had squamous cell carcinoma, 1 un-differentiated carcinoma, 9 adenocarcinoma and 5 adenoid cystic carcinoma. 18 Patients were treated with definitive radiotherapy (interstitial brachy-therapy in 5 patients and external beam therapy in 13 patients), 27 received surgery and radiotherapy. Median length of follow-up was 11 years (range 2.8-16.8 years). 36 Patients had no evidence of disease at the last follow-up visit. All 14 patients with carcinoma of nasal septum had the disease controlled. 9/31 Patients with lesions of lateral wall and floor died of the disease, 5 of uncontrolled local disease, 2 of distant metastases, 2 of both. Disease specific survival rates at 5 and 10 years were 83 and 80%, the corresponding overall survival rates were 75 and 60%. Blindness occurred in 4 patients, 2 due to orbital exenteration and 2 to radiation injury to the cornea and optic pathway. Other infrequent side effects were bone necrosis, dental decay, nasal stenosis and septal perforation. This study indicated that prognosis of patients with nasal cavity carcinoma was better than that of patients with maxillary sinus cancer treated during the same era. In addition, the study showed that carcinoma of the nasal septum were smaller than those of lateral wall and floor at diagnosis, so that excellent control could be achieved by definitive radiotherapy; when accessible, interstitial brachytherapy might be the treatment of choice in such patients.

    The preoperative assessment of renal cell carcinoma (RCC) complicated with acquired renal cystic disease in a 63-year-old male patient on long-term hemodialysis (30 years and 8 months) that was difficult because of no or poor contrast enhancement by dynamic CT scan is reported. Contrast-enhanced ultrasonography with perflubutane microbubbles and positron emission tomography-computed tomography (PET-CT) with 18F-fluorodeoxy glucose (FDG) in addition to dynamic CT were effective and useful for preoperative assessment of this patient. The pathological subtype of RCC in this patient was acquired cystic disease-associated RCC (ACD-associated RCC), which has been newly defined by Tickoo et al. (Am J Surg Pathol 30:141-153, 2006).

    Full Text Available Basal cell carcinoma preferentially occurs in the face where the surgical excision with adequate margin is curative. Sometimes basal cell carcinoma is also reported rarely in other sites especially associated with basal cell carcinoma syndrome. The histological variants are Nodular basal cell carcinoma, Keratotic basal cell carcinoma, Adenoid basal cell carcinoma, Basal cell carcinoma with sebaceous differentiation. Of these variants, Basal cell carcinoma with eccrine differentiation is practically very rare.

  20. Cystic renal neoplasms and renal neoplasms associated with cystic renal diseases in adults: cross-sectional imaging findings.

    Katabathina, Venkata S; Garg, Deepak; Prasad, Srinivasa R; Vikram, Raghu

    2012-01-01

    Cystic renal neoplasms in adults are a heterogeneous group of tumors with characteristic histogenesis, pathological findings, and variable biological profiles. They include disparate entities that are either biologically benign (lymphangioma, cystic nephroma, and mixed epithelial and stromal tumor) or malignant (cystic renal cell carcinoma, multilocular cystic renal cell carcinoma, and primary renal synovial sarcoma). Renal cystic diseases are characterized by cystic changes of the kidneys due to hereditary, developmental, or acquired etiology. Cystic renal diseases such as acquired cystic kidney disease, von Hippel-Lindau disease, and tuberous sclerosis are associated with the development of a wide spectrum of benign and malignant renal neoplasms. Most cystic renal tumors and cystic disease-associated renal neoplasms show characteristic cross-sectional imaging findings that permit accurate diagnosis. In addition, cross-sectional imaging is pivotal in the follow-up and surveillance of adult cystic tumors of the kidney. PMID:23192202

  1. Impact of local radiation in the management of salivary gland carcinomas

    Seventy patients with salivary gland carcinoma (63% major gland and 37% minor gland) are reviewed. Histologies included adenoid cystic (54%), mucoepidermoid (16%), and adenocarcinoma (14%). Patients were analyzed according to extent of surgery and whether or not adjuvant postoperative radiotherapy was given. There is no difference in survival in patients who had complete excision of gross tumor with or without adjuvant radiotherapy. Patients who did not undergo radiotherapy had a 62% actuarial risk of locoregional failure at 5 years, with a 20% risk in the adjuvantly irradiated group (P less than 0.001). A failure analysis demonstrates that among the 44% of patients with recurrence 71% (22/31) failed locoregionally and 69% (21/31) had distant metastases. Twenty-seven percent (19/70) died of disease, with 31% (6/19) dying of locoregional disease and 26% (5/19) of distant disease. Implications for management are discussed

  3. Plain radiographic evaluation of children with obstructive adenoids

    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.

    Full Text Available Background /Objectives: To study 30 cases of patients of chronic adenoiditis with adenoid facies and refractory chronic rhinosinusitis managed by endoscopic assisted adenoidectomy. Materials and method: 7 cases of adenoid facies and 23 cases of chronic refractory rhinosinusitis with adenoiditis were managed by endoscopic assisted adenoidectomy during the study period of 12 months from August 2012 to July 2013. Result: endoscopic assisted adenoidectomy proves to be more effective in managing adenoid facies and chronic refractory rhinosinusitis with adenoid hyperplasia. Conclusion: visualization of the adenoid mass using endoscope helps complete removal of the diseased adenoids. Endoscopic assisted adenoidectomy is treatment of choice in adenoid facies and chronic refractory rhinosinusitis with adenoid hyperplasia and more effective than conventional adenoidectomy.

  5. Clinico-pathological study on non-squamous cell carcinomas of the oral cavity and oropharynx

    We reviewed 22 cases of non-squamous cell carcinoma (NSCC) of the oral cavity and oropharynx that were treated at the Kurume University Hospital between 1976 and 2005. Two percent of the oral carcinomas and 5% of the oropharyngeal carcinomas were NSCCs. The 5-year and 10-year survival rates of NSCC in the oropharynx were 90%. There was no statistically significant difference in survival rate between squamous cell carcinoma (SCC) and NSCC (p=0.06). The 5-year and 10-year survival rates of NSCC in the oral cavity were 75% and 37%, respectively. There was no statistically significant difference in the survival rate between SCC and NSCC. Survival results well correlated with clinical stages. A significant difference between Stage I, II and III versus Stage IV was found (p=0.04). In contrast, no significant relationship was found between survival and histologic type, or between survival and treatment. Patients with adenoid cystic carcinoma of Grade III, peri-neural invasion or vessel invasion, are recommended to receive adjuvant therapy. (author)

    2016-01-01

    Primary salivary gland-type lung cancer is a heterogeneous group of neoplasms arising from the seromucinous glands of the respiratory tract. Histopathologically, they are identical to salivary gland neoplasms of the head and neck. While mucoepidermoid carcinoma and adenoid cystic carcinoma are overwhelmingly the most common subtypes found in the lung, reports of uncommon subtypes can be found in the literature. We report a case of a 73-year-old woman with primary lung salivary duct carcinoma, mucin-rich variant--an exceedingly rare subtype of an already rare malignant salivary-type neoplasm. One case of primary lung salivary duct carcinoma has been reported in the literature; however, the mucin-rich variant has never been described in the lung. Furthermore, the tumor in our case bears a rare BRAF G464V mutation. To our knowledge, this is the first reported case of a BRAF G464V mutation detected in a salivary duct carcinoma or any other salivary-type neoplasm. PMID:26527521

  7. Adenoid basal lesions of the uterine cervix: evolving terminology and clinicopathological concepts

    Russell Michael J

    2006-08-01

    Full Text Available Abstract The epithelial proliferations that are designated adenoid basal carcinoma (ABC in the current classification from the World Health Organization represent 15%. The biologic course of ABCs that are associated with separate malignancies is largely dependent on the clinicopathologic parameters of the associated malignancies. Morphologically pure lesions, in contrast, have largely been associated with favorable patient outcomes, as none of the 66 reported patients have experienced tumor recurrence, metastases or tumor-associated death, irrespective of the modality of treatment. Although the finding of genome integrated high-risk human papillomavirus (HPV types and p53 alterations in adenoid basal lesions (ABL argue in support of their neoplastic nature, we identified no lines evidence that suggest an inherent malignancy for morphologically pure lesions. The finding of morphologic transitions between ABLs and conventional malignancies and shared HPV types in these areas, suggest that ABLs have some malignant potential. However, the precise magnitude of this potential is not readily quantifiable and should not dictate the management of morphologically pure lesions that are entirely evaluable. ABLs continue to occupy a unique position in human oncology in which the term carcinoma (without an in-situ suffix is applied to a tumor that has not been shown to recur, metastasize or cause death. We concur with a previous proposal that the term ABC should be discarded and replaced with Adenoid Basal Epithelioma (ABE. In our opinion, there is insufficient evidence at present time to expose patients with morphologically pure lesions to the ominous implications – social, psychological, medical, financial – of a "carcinoma" diagnosis. Morphologically impure lesions should not be designated ABC or ABE. Furthermore, given the uncertainties regarding the frequency with which ABE are associated with separate malignancies, we suggest that the ABE

    2010-12-01

    Acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) has been recently described. To date, there are no reports on genetic findings of G-band karyotype of ACD-associated RCC. In this article, we report the first report of G-band karyotype of ACD-associated RCC. A 66-year-old Japanese man was found to have a left renal tumor during the follow-up of hemodialysis consequent to chronic renal failure. Left nephrectomy was performed. Histological examination of three tumors in the left kidney showed the cribriform or microcystic growth pattern of neoplastic cells with eosinophilic cytoplasm, and many oxalate crystals were observed. The G-band karyotype of ACD-associated RCC showed 49, X, +X, -Y, +3, +7, +16. These chromosomal abnormalities resemble those of sporadic papillary RCC that has been previously reported. Finally, we suggest that this tumor may show a close relationship between ACD-associated RCC and papillary RCC, but a large-scale study will be needed to clarify the relationship between ACD-associated RCC and papillary RCC.

    Cystic fibrosis represents a major health problem in developed countries. Although its distribution is worldwide, in most developing countries there is little awareness of its prevalence and little opportunity to provide treatment. The improvements in survival of cystic fibrosis patients in developed countries over the past two decades have brought mean life expectancy to 20 years or more, and many adult patients with cystic fibrosis at present are fully integrated in society and have an acce...

  10. A male case of an undifferentiated carcinoma with osteoclast-like giant cells originating in an indeterminate mucin-producing cystic neoplasm of the pancreas. A case report and review of the literature

    2011-09-01

    Full Text Available Abstract We report a rare male case of an undifferentiated carcinoma with osteoclast-like giant cells originating in an indeterminate mucin-producing cystic neoplasm of the pancreas. A 59-year-old Japanese man with diabetes visited our hospital, complaining of fullness in the upper abdomen. A laboratory analysis revealed anemia (Hemoglobin; 9.7 g/dl and elevated C-reactive protein (3.01 mg/dl. Carbohydrate antigen 19-9 was 274 U/ml and Carcinoembryonic antigen was 29.6 ng/ml. A computed tomography scan of the abdomen revealed a 14-cm cystic mass in the upper left quadrant of the abdomen that appeared to originate from the pancreatic tail. The patient underwent distal pancreatectomy/splenectomy/total gastrectomy/cholecystectomy. The mass consisted of a multilocular cystic lesion. Microscopically, the cyst was lined by cuboidal or columnar epithelium, including mucinous epithelium. Sarcomatous mononuclear cells and multinucleated osteoclast-like giant cells were found in the stroma. Ovarian-type stroma was not seen. We made a diagnosis of osteoclast-like giant cell tumor originating in an indeterminate mucin-producing cystic neoplasm of the pancreas. All surgical margins were negative, however, two peripancreatic lymph nodes were positive. The patient recovered uneventfully. Two months after the operation, multiple metastases occurred in the liver. He died 4 months after the operation.

  12. Salivary gland carcinomas: prognostic factors for local control and distant metastasis, the role of radiotherapy

    Purpose: The Dutch Head and Neck Oncology Cooperative Group, in which head and neck groups of all University hospitals and the two cancer institutes are represented, initiated a retrospective study concerning salivary gland carcinomas. A majority of Dutch patients with head and neck carcinomas are treated in the participating centres, and the follow-up is precise. Prognostic factors for local control and survival were studied, with special interest in the role of treatment and the role of histologic type. Methods and materials: Results were obtained of 568 patients with a mean follow-up time of 5 years. The parotid gland was involved in 59%, the submandibular gland in 14%, oral cavity in 24% and 3% was located elsewhere. Mean age was 59 years (range 8-100 yr), 48% was female. T-stage was T1 in 27%, T2 in 44%, T3 in 19% and T4 in 11%. Positive necknodes were seen in 15%, 3% was initially M1. Histologic type was acinic cell carcinoma in 12%, mucoepidermoid ca. in 16%, adenoid cystic ca. in 26%, adenoca. in 24%, carcinoma in pleomorphic adenoma in 8%, squamous cell ca. in 6% and undifferentiated ca. in 7%. Resection margins were radical in 37%, close in 20% and irradical in 40% (3% unknown). Surgery was the primary treatment in 501 patients, combined with postoperative radiotherapy (50-70 Gy, mean dose 62 Gy) in 389 patients. Radiotherapy was the primary treatment in 40 patients (18 M1, 30% N+), 20 patients were not treated and 7 patients were treated otherwise. For statistical analysis the Cox PH regression analysis was used (SPSS-PC+). Results: Actuarial local control after 8 years was 80% for surgery alone and 92% for the combined modality (in which more advanced cases prevaled). Independent factors for local control in the surgery±radiotherapy group were: I:T-stage (T3 vs T1-2: RR 3.7; T4 vs T1-2: RR 11.7), II: anatomic site (oral cavity vs parotid and submandibular gland: RR 0.2) and III: treatment modality (surgery alone vs surgery+radiotherapy: RR 7.0).

  15. Cystic renal tumors: new entities and novel concepts.

    Moch, Holger

    2010-05-01

    Cystic renal neoplasms and renal epithelial stromal tumors are diagnostically challenging and represent some novel tumor entities. In this article, clinical and pathologic features of established and novel entities are discussed. Predominantly cystic renal tumors include cystic nephroma/mixed epithelial and stromal tumor, synovial sarcoma, and multilocular cystic renal cell carcinoma. These entities are own tumor entities of the 2004 WHO classification of renal tumors. Tubulocystic carcinoma and acquired cystic disease-associated renal cell carcinoma are neoplasms with an intrinsically cystic growth pattern. Both tumor types should be included in a future WHO classification as novel entities owing to their characteristic features. Cysts and clear cell renal cell carcinoma frequently coexist within the kidneys of patients with von Hippel-Lindau disease. Sporadic clear cell renal cell carcinomas often contain cysts, usually as a minor component. Some clear cell renal cell carcinomas have prominent cysts, and multilocular cystic renal cell carcinoma is composed almost exclusively of cysts. Recent molecular findings suggest that clear cell renal cancer may develop through cyst-dependent and cyst-independent molecular pathways. PMID:20418675

    Radiograph of the nasopharynx is still the most commonly used imaging method to investigate the adenoidal tissue. Due to the variety and complexity of proposed methods to measure the adenoid size, some radiologists prefer subjective evaluation, which can, however, be imprecise and inaccurate. We review and describe several methods to determine the adenoid size, taking into account the practicity, accuracy and precision with the aim of pointing out the best methods to be applied in daily routine practice.

  18. Computed tomographic evaluation of pancreatic and peripancreatic cystic mass

    Forty-four cases of pancreatic cystic mass (pancreatic pseudocyst 37, pseudocyst caused by pancreatic carcinoma 2, mucous producing caner 2, cystadenoma 1, cystadenocarcinoma 2, and 16 cases of peripancreatic cystic mass (intestinal leiomyosarcoma 10, lymphonode metastasis 3, mesenteric hematoma 1, carcinoma of Vater's papilla 1, duplicating cyst of duodenum 1) were evaluated by computed tomography during the period from April 1978 to December 1984 at Fujita-Gakuen Health University Hospital. The most common cystic masses of pancreatic and peripancreatic lesion were pseudocyst. Although there are many cystic masses mimicking a pancreatic pseudocyst in pancreatic region, sometimes it is impossible to distinguish between cystic mass arising in the pancreas and the adjuvant organ. Difficulties in the computed tomographic differential diagnosis between pancreatic and peripancreatic cystic mass are analyzed and discussed in this paper. (author)

  19. Acquired cystic disease-associated renal cell carcinoma with a focal sarcomatoid component: Report of a case showing more pronounced polysomy of chromosomes 3 and 16 in the sarcomatoid component.

    Tajima, Shogo; Waki, Michihiko; Doi, Wataru; Hayashi, Kazumasa; Takenaka, Syunsuke; Fukaya, Yoshie; Kimura, Ryosuke

    2015-02-01

    Acquired cystic disease (ACD)-associated renal cell carcinoma (RCC) has recently been established. Herein we report the sixth case of ACD-associated RCC with a sarcomatoid change. The patient was a 77-year-old man who regularly underwent hemodialysis for 14 years due to chronic renal failure resulting from IgA nephropathy. On computed tomography, a large right RCC was observed with contrast enhancement in the arterial phase. A nodular protrusion into the perirenal fat was detected. Right nephrectomy was performed under laparoscopy. Surgically resected specimens revealed a tan-to-yellow tumor (95 × 75 × 55 mm) with a whitish nodule (20 × 15 × 15 mm) invading into the perirenal fat. Histopathologically, the large carcinoma component of the tumor displayed a cribriform or microcystic growth pattern with deposition of oxalate crystals. The whitish nodule corresponded to the sarcomatoid component, and the spindled and pleomorphic tumor cells showed diffuse positivity of p53 on immunohistochemistry. Fluorescence in situ hybridization revealed trisomy of chromosomes 3 and 16 in the carcinoma component, as was expected from the literature. In addition, increased polysomy of these chromosomes was also observed in the sarcomatoid component. This finding may be related to the development of the sarcomatoid component along with the TP53 mutation. PMID:25424516

    We illustrate the sonographic findings of malignant breast masses that can mimic a cystic component with pathologic correlations. The disease entities presented in this study include infiltrating ductal carcinoma, ductal carcinoma in situ (DCIS), papillary carcinoma, mucinous carcinoma, medullary carcinoma, metaplastic carcinoma, and a malignant phyllodes tumor. Malignant masses with a cystic component are often characterized by well-circumscribed round, oval, or lobular masses, thereby appearing benign on ultrasonography. On pathology, the cystic component of a malignant mass is identified by cystic degeneration, hemorrhage, necrosis, or ductal dilatation. If the mass is well-circumscribed with a cystic component, a biopsy should be considered in the analysis of the solid component within a mass.

  1. Multilocular cystic renal tumor in children: radiologic-pathologic correlation.

    Agrons, G A; Wagner, B J; Davidson, A J; Suarez, E S

    1995-05-01

    Multilocular cystic renal tumor is a term that encompasses two histologically distinct but grossly indistinguishable lesions: cystic nephroma and cystic partially differentiated nephroblastoma (CPDN). Cystic nephroma is a segmental, purely cystic mass characterized by multiple septations composed entirely of differentiated tissues, without blastemal elements. CPDN is also a multiloculated lesion without nodular solid components, but its septa contain embryonal cells. Multilocular cystic tumors primarily affect boys during early childhood, with a substantial number of the lesions containing blastema (CPDN), and adult women, with lesions that more commonly lack septal blastema (cystic) nephroma). As a rule, nephrectomy is curative and the clinical course benign, but CPDN may recur locally. Although cystic nephroma and CPDN cannot be distinguished radiologically, failure to do so has no practical impact on management, since all of these tumors are surgically removed. However, the differential diagnosis includes other pediatric cystic renal masses that may require different treatment stratagems: Wilms tumor with cyst formation due to hemorrhage and necrosis, cystic clear cell sarcoma, cystic mesoblastic nephroma, cystic renal cell carcinoma, multicystic dysplastic kidney, and segmental multicystic dysplasia in a duplicated renal collecting system.

  2. Long-term outcome of patients treated by radiation therapy alone for salivary gland carcinomas

    Purpose: To review a single-institution experience with the management of salivary gland cancers treated by radiation alone. Methods and Materials: Between 1960 and 2004, 45 patients with newly diagnosed salivary gland carcinomas were treated with definitive radiation to a median dose of 66 Gy (range, 57-74 Gy). Distribution of T-stage was: 24% T1, 18% T2, 31% T3, and 27% T4. Histology was: 14 mucoepidermoid (31%), 10 adenocarcinoma (22%), 8 adenoid cystic (18%), 4 undifferentiated (9%), 4 acinic (9%), 2 malignant mixed (4%), 2 squamous (4%), and 1 salivary duct carcinoma (2%). No patient had clinical or pathologic evidence of lymph node disease. Median follow-up was 101 months (range, 3-285 months). Results: The 5-year and 10-year rate estimates of local control were 70% and 57%, respectively. A Cox proportional hazard model identified T3-4 disease (p = 0.004) and radiation dose lower than 66 Gy (p = 0.001) as independent predictors of local recurrence. The 10-year overall survival and distant metastasis-free rates were 46% and 67%, respectively. Conclusion: Radiation therapy alone is a reasonable alternative to surgery in the definitive management of salivary gland cancers and results in long-term survival in a significant proportion of patients. Radiation dose in excess of 66 Gy is recommended

    In the 1930s, when cystic fibrosis (CF) was first clearly recognised, it was a disorder that inevitably led to death in early childhood from respiratory failure and malnutrition. Since that time, antibiotic treatment and improving nutrition have brought increasing hope to sufferers from the disorder, so that increasing numbers of children have lived on into adult life. Chaired by Professor John Walker-Smith, and attended by a group of leading experts in field at the time, this transcript disc...

  7. Radiographic evaluation of adenoidal size in children: methods of measurement and parameters of normality

    Radiograph of the nasopharynx is still the most commonly used imaging method to investigate the adenoidal tissue. Due to the variety and complexity of proposed methods to measure the adenoid size, some radiologists prefer subjective evaluation, which can, however, be imprecise and inaccurate. We review and describe several methods to determine the adenoid size, taking into account the practicity, accuracy and precision with the aim of pointing out the best methods to be applied in daily routine practice.

  9. Long-term Outcomes and Quality of Life of 186 Patients With Primary Parotid Carcinoma Treated With Surgery and Radiotherapy at the Daniel den Hoed Cancer Center

    Purpose: To assess the outcomes, toxicity, and quality of life (QOL) of patients with primary parotid carcinoma treated with surgery and postoperative radiotherapy at the Daniel den Hoed Cancer Center. Methods and Materials: Between 1995 and 2010, 186 patients with parotid carcinoma were treated with parotidectomy with or without neck dissection, followed by radiotherapy. Elective nodal irradiation (ENI) was applied to high-risk, node-negative disease. End points were locoregional control (LRC), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS), late toxicity, and QOL. Results: After a median follow-up of 58 months (range, 4–172 months), the 5-year Kaplan-Meier estimates for LRC, DFS, CSS, and OS were 89%, 83%, 80%, and 68%, respectively. Forty-five events were reported: 24 distant metastases (DM) and 21 locoregional failures (LRF). Event-free survival rates by histological types were 89%, 78%, 76%, 74%, and 70% for acinic cell, mucoepidermoid, adenoid cystic, adenocarcinoma, and squamous cell carcinoma, respectively. More LRF were reported in patients with squamous cell and high-grade mucoepidermoid carcinoma (21% and 19%, respectively) than in patients with other histological types (p = 0.04) and more DM in patients with adenoid cystic and adenocarcinoma (20% and 19%, respectively) than in patients with other types (p = 0.03). None of the high-risk node-negative patients who received ENI developed regional failure. On multivariate analysis, T stage, N stage, grade, and presence of perineural invasion and facial paralysis correlated significantly with DFS. The 5-year cumulative incidence of grade ≥2 late toxicity was 8%. QOL scores deteriorate during and shortly after treatment but returned in almost all scales to baseline scores within 6 months. Conclusions: Of the entire group, surgery and postoperative radiotherapy resulted in excellent outcomes with minimal side effects and preservation of good QOL scores. However, in

  11. Role of fluorine-18-fluorodeoxyglucose positron emission tomography-computed tomography in management of pulmonary mucoepidermoid carcinomas and review of literature.

    Krishnamurthy, Arvind; Ramshankar, Vijayalakshmi; Majhi, Urmila

    2016-01-01

    Pulmonary mucoepidermoid carcinoma (PMEC) is a rare tumor of bronchial gland origin with a striking resemblance to MEC of the salivary glands. The World Health Organization classifies PMECs as "salivary gland type" tumors along with pulmonary adenoid cystic carcinomas and epimyoepithelial lung carcinomas. Their description in literature is largely limited to a few case series/case reports. Further, the experience of imaging in these tumors with fluorine-18 fluorodeoxyglucose positron emission tomography-computed tomography ( (18)F-FDG PET-CT) is also limited and evolving largely due to rarity of PMEC. We recently managed an interesting case of a PMEC and reviewed the literature surrounding this rare tumor with an emphasis on the role of (18)F-FDG PET-CT in its management. An (18)F-FDG PET-CT appears to be a useful imaging modality for predicting the tumor grade of patients with PMECs; further, there is emerging data to suggest the role of (18)F-FDG PET-CT for predicting the long-term prognosis of patients with PMEC.

  13. Immunohistochemical study of androgen, estrogen and progesterone receptors in salivary gland tumors

    Fabio Augusto Ito

    2009-12-01

    Full Text Available The aim of this work was to study the immunohistochemical expression of androgen receptor, estrogen receptor and progesterone receptor in pleomorphic adenomas, Warthin's tumors, mucoepidermoid carcinomas and adenoid cystic carcinomas of salivary glands. A total of 41 pleomorphic adenomas, 30 Warthin's tumors, 30 mucoepidermoid carcinomas and 30 adenoid cystic carcinomas were analyzed, and the immunohistochemical expression of these hormone receptors were assessed. It was observed that all cases were negative for estrogen and progesterone receptors. Androgen receptor was positive in 2 cases each of pleomorphic adenoma, mucoepidermoid carcinoma and adenoid cystic carcinoma. In conclusion, the results do not support a role of estrogen and progesterone in the tumorigenesis of pleomorphic adenomas, Warthin's tumors, mucoepidermoid carcinomas and adenoid cystic carcinomas. However, androgen receptors can play a role in a small set of salivary gland tumors, and this would deserve further studies.

    2015-09-01

    Full Text Available OBJECTIVES: To identify the common bacteria found in the nasopharynx of patients of serous otitis media, to study the prevalence of adenoiditis in patient of serous otitis media and to study the bacteria isolated from operated adenoid tissue of patients of serous otitis media. METHOD AND MATERIA LS : Study was carried out on clinically diagnosed 40 cases of serous otitis media. Patients were operated under general anaesthesia. At the commencement of the surgery, a sterile swab was taken with an applicator from the surface of the adenoid. Prior to surgery, the adenoid tissue was palpated and confirmed. Adenoidectomy was done by curettage method using adenoid curette and the specimen was immediately transported in normal saline to the microbiology lab in a sterile bottle along with the surface swab. RESULT: 95% culture shows bacterial growth , males are more common in serous otitis media and most bacteria isolated from nasopharyngeal swab and adenoid are Gram positive bacteria includes Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus species, Streptococcus viridians, Streptococcus pyogenes and Gram negative bacteria includes Moraxella catarrhalis, Klebsiella pneumonia. CONCLUSION: T he nasopharyngeal and adenoid bacterial flora is polymicrobial in nature and there is no difference in the pathogens isolated from nasopharynx swab or adenoid culture in patients of serous otitis media.

  15. [Immunomodulators for topical application to prevent and manage chronic adenoiditis in children].

    Garashchenko, T I; Zelenkova, I V; Alferova, M V

    2011-01-01

    The authors report the results of a study on the efficacy of topical application of the immunomodulator IRS 19 in children presenting with chronic adenoiditis and grade I-III hypertrophy of adenoid vegetation. The use of this preparation is shown to faster and more efficaciously normalize the volume of the lymphoid tissue than irrigation of the nasopharynx with saline solutions. Moreover, the treatment of chronic adenoiditis with IRS 19 promoted normalization of biocenosis of the nasopharyngeal secretion and significantly decreased the abundance of pathogenic microflora. Specifically, the overall frequency of exacerbations and the frequency of exacerbations of adenoiditis decreased three- and two-fold respectively while the duration of the disease shortened. It is recommended that the topical immunomodulator IRS 19 should be included in the programs of planned seasonal treatment of children suffering chronic adenoiditis (to be applied at least 2-3 times annually).

    @@ Mucinous cystic neoplasms (MCNs) of the pancreas are a distinct entity, account for 1% of pancreatic exocrine tumors. MCNs can be classified histologically as adenomas, borderline tumors, or carcinomas. Because several evidences showing that mucinous cystadenomas are poten- tially malignant and may transform into cystadeno- carcinomas, particularly if treated by drainage, these tumors should be identified accurately.1

  19. Maxillary sinus carcinoma: Natural history and outcome

    To assess natural history, treatment outcome and pattern of relapse in patients with maxillary sinus carcinoma. A review was conducted of the medical records of all adult patients with maxillary sinus carcinoma, who were treated at King Faisal Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia, between January 1990 and December 1999. A total of 60 patients were identified for analysis, 36 men and 24 women; the median age was 58-years (range 23-95). Major presenting symptoms were facial swelling 55%, facial pain 50%, and nasal obstruction 43.4%, with a median duration of 5-months (range 1-24). Histology was quamous cell carcinoma in 71.7% and adenoid cystic in 16.7%. They were restaged according to American Joint Committee on Cancer classification 1997 as II, III and IV in 1, 10 and 49. Thirty patients received treatment with curative intent (surgery in 4 patients, radiotherapy in 2, and combined modality in 24), 6 patients refused treatment and 24 were treated palliatively. With a median follow up of 50-months (range 2-128) in surviving patients treated with a curative intent, 12/30 failed locally, 4/30 in the regional neck nodes and 2/30 had systemic relapse. The actuarial 5-year overall survival (OS), relapse free survival (RFS) and local control rate (LC) were 55%, 39% and 51%. Treatment modality was the only significant prognostic factor for outcome, with 5 year OS, RFS and LC of 72%, 49% and 61%, for combined modality using surgery followed by radiotherapy compared to 0% for single approach (p=0.0003, p=0.0052 and p=0.0098). This study indicates that the majority of our patients presented with advanced disease, resulting in poor outcome to conventional treatment modalities. Efforts should be directed to minimize the delay in diagnosis at the primary care level. Combined modality treatment should be offered to all patients with locally advanced disease. New approaches such as neoadjuvant or concurrent chemoradiotherapy with or without surgery need to

    2015-06-01

    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.

    Cystic renal lesions are commonly encountered in abdominal imaging. Although most cystic renal lesions are benign simple cysts, complex renal cysts, infectious cystic renal disease, and multifocal cystic renal disease are also common phenomena. The Bosniak classification system provides a useful means of categorizing cystic renal lesions but places less emphasis on their underlying pathophysiology. Cystic renal diseases can be categorized as focal, multifocal, or infectious lesions. Diseases that manifest with focal lesions, such as cystic renal cell carcinoma, mixed epithelial and stromal tumor, and cystic nephroma, are often difficult to differentiate but have differing implications for follow-up after resection. Multifocal cystic renal lesions can be categorized as acquired or heritable. Acquired entities, such as glomerulocystic kidney disease, lithium-induced nephrotoxicity, acquired cystic kidney disease, multicystic dysplastic kidney, and localized cystic renal disease, often have distinct imaging and clinical features that allow definitive diagnosis. Heritable diseases, such as autosomal dominant polycystic kidney disease, von Hippel-Lindau disease, and tuberous sclerosis, are usually easily identified and have various implications for patient management. Infectious diseases have varied imaging appearances, and the possibility of infection must not be overlooked when assessing a cystic renal lesion. A thorough understanding of the spectrum of cystic renal disease will allow the radiologist to make a more specific diagnosis and provide the clinician with optimal recommendations for further diagnostic testing and follow-up imaging.

  10. Carcinoma multiplex

    Multiple primaries in a single patient are uncommon, though not very rare. The existence of such cancers in two un-related, non-paired organs is even more un-common. Here, we present a case of 55 years old male who presented to us with a mucoepidermoid carcinoma of the parotid gland and was operated. Later on, he presented with a large cystic swelling in the pelvis which turned out to be pseudomyxoma peritonei. A review of slides and immunohistochemistry indicated it to be adenocarcinoma colon. He presented again with recurrent mucoepidermoid carcinoma of the parotid which was operated successfully with the use of myocutaneous flap for wound closure. He is currently undergoing chemotherapy. In order to establish a separate mono-clonal etiology of both tumours, immunohistochemistry was performed. To the best of our knowledge, carcinoma multiplex in the colon and the parotid has never been reported before. (author)
