“…[9] Other than salivary glands, this tumor also occurs in the breast, skin, nasal cavity, nasopharynx, larynx and lung. [101112] We herein report a rare case of myoepithelial carcinoma of a 55-year-old female at buccal mucosa, a rare location. To the best of our knowledge, there are only eight cases of myoepithelial carcinoma of buccal mucosa are reported in the literature.…”

Myoepithelial carcinoma is a rare neoplasm of salivary glands that account for < 1% of all salivary gland tumors. The most common sites of involvement are major salivary glands mainly parotid gland. Intraorally, it can arise from minor salivary glands; palate is the most common site of occurrence. It also occurs in nasopharynx, paranasal sinuses, nasal cavity and larynx in head and neck region. Myoepithelial tumors were first described in 1943. Their malignant variant, myoepithelial carcinoma, was first reported by Stromeyer et al., in 1975, characterized by distinct morphologic heterogeneity and an infiltrative growth pattern into adjacent tissues. Here, we report a rare case of a 55-year-old female with myoepithelial carcinoma of buccal mucosa. It was also rare because of unusual location of tumor. Our patient was treated with wide local resection and remained free of disease for 15 months.

“…[ 2 3 4 5 ] MECAs have been described in other sites such as lungs, skin, breast, stomach, and soft tissues. [ 6 7 8 9 ] The mean age at presentation is in the fifth to sixth decade and in general, MECAs exhibit no gender predilection, with the exception of primary lung MECAs that affect males more than females. The majority of patients with head and neck tumors present with the primary complaints of a painless mass with duration of symptoms ranging from 2 months to 7 years.…”

Pleural fluid metastases of myoepithelial carcinoma: A case report and review of the literature

et al. 2016

Myoepithelial carcinoma (MECA) is one of the rarest salivary gland neoplasms, which may either arise de novo or develop within a preexisting pleomorphic adenoma or benign myoepithelioma. The tumor occurs mainly in the parotid gland followed by minor salivary glands and other body sites. As a result of their morphologic heterogeneity, they can be confused easily with many tumors. Awareness of their unique cytoarchitectural patterns and immunohistochemical profile is crucial for accurate identification. Herein, we report a rare case of a 51-year-old female patient with MECA of the maxillary sinus that metastasized to the pleural fluid. To the best of our knowledge, this is the first case of pleural fluid involvement by MECA reported in the literature.

“…[ 1 ] These tumors arise commonly in salivary glands and very rarely in skin, soft tissue, retroperitoneum, breast, vulva, stomach, and lung. [ 2 3 4 5 6 7 ] Myoepithelial carcinoma of the breast is extremely rare, and <40 case reports have been published in English literature. Most of the reports lay emphasis on diagnosis and pathology and very few mention of the chemotherapy regimen used and its response.…”
