Neoplasms of the major and minor salivary glands are morphologically and a clinically diverse group of neoplasms which lead the clinician to diagnostic and management challenges. This article aims to report a case of mucoepidermoid carcinoma in 83 - year - old woman who presented in the dermatology clinic with a tumour mass in the left auricular area. The patient complained of pain and abnormal...

Rationale: Mucoepidermoid carcinoma (MEC) of the breast is a rare entity comprising specific morphological and immunohistochemical features, and has been previously only reported in 33 cases. Patient concerns: Four cases of MEC of the breast are reported in this study. All patients were women with ages ranging from 39 to 66 years. The lesions consisted of neoplastic solid nests and cystic space...

Low-grade mucoepidermoid carcinoma (LG MEC) is a rare tumor which can occur in the minor salivary glands as intraoral lesion, more frequently in the palate and very rarely in the floor of the mouth. Traditionally, the diagnosis has been made on surgical resection specimens only. There is new growing evidence that these lesions can be accurately diagnosed by a fine-needle aspiration (FNA) biopsy...

We treated two patients requiring nasolabial flap reconstruction. The first patient was a 75-year-old man with mucoepidermoid carcinoma in the left-side floor of the mouth; requiring resection of the floor of the mouth, partial mandibulectomy, and left supraomohyoid neck dissection. The second patient was a 74-year-old man with recurrent acinic cell carcinoma in the anterior oral floor infiltra...

Rats (Ar/IRE Wistar strain) exposed for 12 months to vapors of vinyl chloride developed tumors of the skin, lungs, and bones. The cutaneous tumors, which always appeared in the area in which submaxillary and parotid glands are located, have been histologically recognized as epidermoid carcinomas, papillomas, and mucoepidermoid carcinomas. The morphological characteristics of lung tumors, which ...

OBJECTIVE The maximum standardized uptake value (SUVmax) of pulmonary mucoepidermoid carcinoma (PMEC) in fluorine-18fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) was evaluated as a preoperative predictor of pathologic grade and survival rate. MATERIALS AND METHODS Twenty-three patients who underwent preoperative PET/CT and complete resection for PMEC w...

Malignant tumors of the paranasal sinus are uncommon, constituting less than 1% of all malignancies and 3% of all head and neck cancers. Nonsquamous cancers of the maxillary sinus are even rarer as is evident from the limited data available on the clinical characteristics and outcomes. Mucoepidermoid carcinoma accounts for 13% of all malignancies occurring in maxillary sinus. We report a rare c...

Salivary gland carcinomas are a rare and clinically diverse group of neoplasms among which mucoepidermoid carcinomas (MEC) are reported to be most frequently occurring. MEC display a variety of biological behaviors and variable natural history. We report a case of mucoepidermoidcarcinom. Histopathological features suggested intermediate grade mucoepidermoid carcinoma. Surgical resection was don...

Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland neoplasm. Central MEC (CMEC) is a rare primary intraosseous bony lesion with an incidence of 2%-4.3% of all MECs reported. In this article, we present a rare case of a CMEC in the anterior region of maxilla at a 43-year-old female patient that was arising from a dentigerous cyst. CMECs are extremely rare tumor. They are ...
