Abstract Introduction/Objective Human Papilloma Virus (HPV)-related multiphenotypic sinonasal carcinoma, previously known as HPV-related sinonasal carcinoma with adenoid cystic carcinoma-like features, is a rare type of sinonasal carcinoma with both epithelial-derived and salivary gland-type morphologic features. It is associated with high-risk HPV, but lacks MYB gene rearrangements. Methods/Case Report We report a case of a 59-year-old male who presented with a rapidly growing sinonasal mass. On MRI, a left nasal cavity lesion was identified growing laterally along the frontal process of the maxilla, extending into the middle meatus and into the maxillary sinus. Patient underwent a complex left medial maxillectomy, spheno- ethmoidectomy, and sinusotomy. On gross evaluation, the left inferior turbinate and sidewall demonstrated a 4 cm unremarkable turbinate with attached friable soft tissue. Microscopic examination revealed sections of carcinoma with various architectural patterns comprised of foci with adenoid cystic carcinoma-like morphology, basaloid squamous cell carcinoma and adenocarcinoma. The tumor showed positive immunostaining for P40, but focal reactivity to S100 and rare scattered reactivity with CD117. INI-1 immunostain was retained in tumor cells. P16 immunostain was strong and diffuse and high-risk cocktail HPV RNA ISH was positive. However, MYB FISH testing was equivocal. Morphologic and immunophenotypic findings were consistent with HPV-related multiphenotypic sinonasal carcinoma. The tumor involved the olfactory nerve fibers requiring a skull base resection and showed extension into the dura mater. Results (if a Case Study enter NA) NA Conclusion HPV related multiphenotypic sinonasal carcinoma is a recently described entity that can pose significant diagnostic challenge. It typically has an indolent clinical course with potential for late recurrences. This case study highlights the potential aggressive nature of this type of sinonasal carcinoma, despite association with high-risk HPV, and use of ancillary testing in aiding diagnosis.

Abstract Introduction/Objective Adenoid cystic carcinoma (ACC) of the female genital tract is rare and the published literature is sparse. In the vulva it is considered to arise from Bartholin’s gland whereas, in cervix it arises from the reserve cells. Although morphologically ACC of female genital tract is similar to its counterparts in salivary glands, the clinical behavior is different. Methods/Case Report We describe the clinicopathologic and immunohistochemical features of three cases of adenoid cystic carcinoma of female genital tract with review of literature. The age of our patients ranged from 48 to 75 years with tumors ranging from 1.9 to 3.9 cm. The tumor sites were vulva (2 cases) and cervix (1 case). Two of the 3 patients presented with mass lesions and one patient presented with postmenopausal bleeding. Microscopically, all tumors showed classic morphologic features with cribriform, tubular and solid patterns. On immunohistochemistry, CD117 was consistently reactive in all 3 cases. In addition, the ductal and myoepithelial cell population were highlighted by keratin cocktail and p63 respectively. P16 was diffuse and block-like positive in two cases (one vulvar and cervical ACC). High risk HPV (HPV 33) was detected in one case of vulvar ACC. Two patients underwent surgical excision while one patient was deemed unfit for surgical treatment. All 3 patients received radiation therapy. On follow- up that ranged from 17 to 76 months, one patient is alive without evidence of disease. One patient died of disease with local recurrence and lung metastasis. The other patient died of complications (radiation proctocolitis with colonic perforation). Results (if a Case Study enter NA) NA Conclusion Our cases highlight the aggressive behavior of adenoid cystic carcinoma in the female genital tract and the need for close follow-up. Also high risk HPV has been demonstrated in cervical ACC previously, but our series demonstrates high risk HPV association with vulvar ACC.

History Of

Adenoid cystic carcinoma is a relatively uncommon tumour of salivary, glands and is characterised by a prolonged clinical course and a fatal outcome. It was first described as `cylindroma' by Billroth in 1859. Half of these tumors occur in glandular tissues other than the major salivary glands; principally in the hard palate, but they can also arise in the tongue and minor salivary glands. Unusual locations include the external auditory canal, nasopharynx, lacrimal glands, breast, vulva, esophagus, cervix and Cowper glands. The long natural history of this tumor and its tendency for local recurrence are well known. JMS 2012;15(1):76-77.

Malignant tumours of the salivary glands in children are extremely rare. We present here a 12-year-old girl initially diagnosed as pleomorphic adenoma on fine needle aspiration biopsy, and adenoid cystic carcinoma (ACC) after the lesion was excised and examined by histopathology. A wide resection of the lesion and bilateral supraomyohyoid neck dissection was performed. To our knowledge this is one of the youngest patients with ACC of the minor salivary glands. Due to its benign histological appearance, the biological agressiveness of ACC is usually underestimated. Although fine needle aspiration cytology (FNAC) is very valuable in diagnosis, cytological variations of pleomorphic adenoma must be considered. ACC of the tongue in a young age group should be treated with wide resection and selective neck dissection if the tumour is localized in places where the risk of metastasis is increased and if there is a clinically palpable lymph node. In such cases the clinician should not avoid radical operations even in a young patient.

Objectives Kallikrein-related peptidase 10 (KLK10) has been implicated in the development of several types of cancer. The purpose of this study was to analyze the expression of KLK10 in 3 types of salivary gland tumour and normal salivary glands. Materials and methods: A standard immunoperoxidase staining technique was used to assess the Immunoexpression profile of KLK10 in normal salivary glands and 3 types of salivary gland tumour: pleomorphic adenoma, adenoid cystic carcinoma and mucoepidermoid carcinoma. Results Pleomorphic adenomas showed significantly lower KLK10 levels than control tissues. Neither of the malignant tumours (adenoid cystic carcinoma and mucoepidermoid carcinoma) showed a significant alteration in the immunoreactive scores of KLK10 in comparison with the normal salivary gland tissues. KLK10 immunoreactive scores were comparable in adenoid cystic carcinoma and mucoepidermoid carcinoma. Pleomorphic adenoma had significantly lower levels of KLK10 than mucoepidermoid carcinoma. Conclusions The finding of lower KLK10 levels in pleomorphic adenoma suggests aberrant expression in a tumour that develops primarily from myoepithelial cells. A kallikrein cascade may play a role in the development and/or outcome of some salivary gland tumours.

Background: Salivary gland tumors include a wide variety of benign and malignant tumors in the oral and maxillofacial region. Although these tumors are not common, they are not rare. The prevalence of these tumors varies with regard to age, gender, and their location in the body. Objectives: This study aimed to evaluate the frequency of benign and malignant salivary gland tumors in patients referred to three referral hospitals in Tehran, Iran. Methods: This retrospective cross-sectional study examined the demographic and pathologic records of the patients with salivary gland tumors submitted to the Department of Pathology of Amir Alam, Loghman Hakim, and Shohada Hospitals from 2005 to 2016. In this study, the histological variants of salivary gland tumors and clinical parameters such as age, gender, and the location of the tumor were examined. The clinical data were analyzed using SPSS software version 21. Results: Of 137632 patient records, 1180 cases were salivary gland tumors. Pleomorphic adenoma in 794 cases (67.3%) and adenoid cystic carcinoma in 109 cases (9.2%) were the most common tumors, respectively. Salivary gland tumors were more common in males, and the participants’ mean age was 42.86 ± 16.5 years. The most common site was parotid and minor salivary glands, with 937 (79.4%) and 137 (12%) cases, respectively. Conclusions: In this study, the most common benign tumor was pleomorphic adenoma in the parotid gland, and the most common malignant tumor was adenoid cystic carcinoma in the major salivary glands. Furthermore, benign tumors were more frequent than malignant tumors.
