Dermal analogue tumor of the salivary gland diagnosed by fine needle aspiration cytology. A case report

BACKGROUND: Dermal analogue tumor of the salivary gland is a rare form of salivary gland adenoma. Cytologic and histologic findings of 1 case are presented. CASE: A 74-year-old-female had a dermal analogue tumor in the parotid gland diagnosed by fine needle aspiration cytology (FNAC). Aspiration smears were characterized by aggregates of uniform epithelial cells, and cell groups bordered on thick, basement membrane-like material. The tumor was excised, and the histologic sections confirmed the cytologic diagnosis. CONCLUSION: Dermal analogue tumor of the salivary gland has a distinctive cytomorphologic appearance, and diagnosis of this neoplasm by FNAC is possible. Preoperative FNAC of salivary gland lesions is important in planning the most appropriate type of treatment.
