Background Hyalinizing clear cell carcinomas (HCCCs) are rare, low-grade, malignant tumors which most often arise from the minor salivary glands primarily in palate and tongue but can arise in any location with minor salivary glands including the nasopharynx. Methods A case report of primary nasopharyngeal HCCC is presented. Because of the rarity of this tumor and location, a literature search was conducted to determine the most common presenting symptoms, treatment strategies, and outcomes. Results A 48-year-old man underwent biopsy of a 4.5 cm mass of the right nasopharynx with pathology suggesting an intermediate grade mucoepidermoid carcinoma. After discussing management with the patient, an endoscopic resection was performed. Final pathology revealed an HCCC which was confirmed after negative Mastermind-like 2 (MAML2) and positive Ewing sarcoma breakpoint region 1 (ESWR1) gene rearrangements on fluorescence in situ hybridization (FISH) studies. Literature review of other nasopharyngeal HCCC cases shows diverse presentation and overall excellent prognosis through surgical and radiation therapy. Conclusion HCCCs are rare, low-grade malignant tumors of the minor salivary glands and can present as a nasopharyngeal mass. Presenting symptoms are diverse but frequently involve otologic and sinonasal disturbances. HCCC is an indolent tumor with an excellent prognostic outcome when treated appropriately with surgical resection and adjuvant radiotherapy.

Hyalinizing clear cell carcinoma (HCCC), so-called clear cell carcinoma, not otherwise specified (CCC (NOS)), of the salivary glands is a rare and low-grade malignant tumor. We report a case of HCCC so-called CCC (NOS) (referred to as HCCC) of the minor salivary gland of the buccal mucosa. A 52-year-old woman had presented with a gradually growing and indolent mass in the right buccal mucosa for about two years. The first biopsy histopathologically suggested the possibility of malignancy derived from the minor salivary glands. A month later, she visited our hospital. The tumor measured approximately 1.5 cm in diameter and was elastic hard, smooth, and well movable. Image examinations demonstrated internal homogeneity of the lesion, which had a smooth margin, in the right buccal mucosa. Complete tumor resection followed by covering with a polyglycolic acid sheet and fibrin glue spray was performed without surgical flap reconstruction. Histopathological findings revealed proliferating tumor cells with clear cytoplasm surrounded by hyalinizing stroma in the submucosal minor salivary glands. Immunohistochemical stains revealed these tumor cells to be positive for epithelial cell markers but negative for myoepithelial ones. These findings confirmed the diagnosis of HCCC. Good wound healing and no evidence of local recurrence and metastasis have been shown since surgery.

Polymorphous low-grade adenocarcinoma is a rare salivary gland malignant tumor of low aggressiveness, commonly occurring in minor salivary glands. Its origin in major salivary glands is considered exceedingly rare. We report a case of polymorphous low grade adenocarcinoma arising from left parotid in a 21-yearold female patient.Journal of Pathology of Nepal (2012) Vol. 2, 331-334DOI: http://dx.doi.org/10.3126/jpn.v2i4.6890

Retroperitoneal liposarcomas (RLPS) are rare tumors that have variable clinical behavior and complex treatment strategies based on presentation, histopathology, and genomics. Early identification is critical, and complete surgical resection remains the primary treatment, although chemotherapy and radiation are used on individual bases. Presenting symptoms are often nonspecific; therefore, a high degree of suspicion is essential for early diagnosis. In this report, the management of a 37-year-old otherwise healthy male with a large RLPS causing right groin/testicular pain is presented. After three evaluations in the emergency department, the patient was diagnosed and received two cycles of doxorubicin/ifosfamide/mesna (AIM) neoadjuvant chemotherapy. His physical exam on presentation for second opinion demonstrated a large palpable abdominal mass and fullness around the right spermatic cord. There was no appreciable change in tumor size or distant metastases on repeat scanning. Given some obstructive symptoms, a multidisciplinary team advised neoadjuvant radiation followed by radical resection of RLPS. Final pathology demonstrated a 31-cm grade II well-differentiated (WD) liposarcoma with low-grade dedifferentiation. Scattered foci of microscopic positive WD margins were noted, and the remainder of margins were negative. Genomic evaluation showed amplification of CDK4, MDM2, and FRS2. A concise literature review of common presentations, histopathology, genomics, and treatment information is discussed herein. Thorough physical exams, attention to subtle findings, appropriate medical imaging studies, and a high index of suspicion when evaluating vague symptomatology can lead to earlier diagnosis and treatment of RLPS, and ultimately better patient outcomes.

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

Polymorphous low-grade adenocarcinoma (PLGA) is a rare tumour that mostly affects oral minor salivary glands. Our review of the literature found that there are only two reported cases of PLGA originating in the nasopharynx. Another nasopharyngeal PLGA in a 14-year-old boy is reported, focusing on the histopathological features and ultrastructural findings.

AbstractFibrosarcomas are malignant tumors of the connective tissue, which are characterized by proliferation of fibroblasts. Most of these tumors are localized subcutaneously and cause different symptoms depending on their location. The case report describes a dermal tumor on the outside of the pinna in a 7-year-old female Cashmere goat. The tumor was surgically removed and histopathological examination revealed a low grade fibrosarcoma. Although tumors are rare in ruminants because of the animals’ short lifespan (age of slaughtering in most cases < 24 months) in modern production processes, they should be considered as a differential diagnosis.

Abstract Introduction/Objective Myoepithelial carcinoma is identified by nearly exclusive myoepithelial differentiation and evidence of malignancy. It may arise de novo or in preexisting benign tumors including pleomorphic adenoma and benign myoepithelioma. It occurs most commonly in the parotid gland followed by submandibular glands, minor salivary glands, and occasionally in the sublingual gland. Nasopharyngeal origin has been rarely reported. Methods/Case Report An afebrile 19-year-old female presented to the emergency department with persistent facial pressure, otalgia (right side greater than left side), rhinorrhea, and several episodes of epistaxis. One month before, she has been treated with Amoxicillin for three days with no relief, where Augmentin started for her for five days. About four days prior presentation, she was placed on Prednisone and Cefdinir. Over the next several days, she began having throat pain with difficulty swallowing. Routine blood work revealed a leukocytosis of 14.2 with normal differentiation. CT of the neck showed a large soft tissue mass centered at the right nasopharynx. Flexible nasal endoscopy performed bilaterally to reveal the nasopharynx is entirely obstructed with a lobulated mass filling the nasopharynx. On the right side, it extends into the posterior nasal passage filling the sphenoethmoid recess and the posterior floor of the nasal passage. Outpatient biopsy from nasopharynx mass is also performed. Results (if a Case Study enter NA) Mass biopsy reveals a mucinous and chondromyxoid background with mixed epithelial and myoepithelial differentiation. The is squamous metaplasia of myoepithelial cells and prominent mitotic activity and apoptotic activity. Immunohistochemistry was positive for CK5/6, calponin, BCL2, SMA, BerEp4, Sox10, and a proliferative index up to 40%. Based on this information Myoepithelial Carcinoma ex-pleomorphic adenoma of the nasopharynx is the diagnosis. Conclusion Carcinoma ex pleomorphic adenoma is usually a high-grade malignancy. It occurs most commonly in the parotid gland, followed by submandibular glands, minor salivary glands, and occasionally in the sublingual gland. Our case is one of the few cases of myoepithelial carcinoma arising in nasopharyngeal pleomorphic adenoma.
