Context: Myoepithelial carcinoma (MECA) represents < 1% percent of salivary gland (SG) tumors with a mean age of 55 years. These tumors can arise de novo or in association with pre-existing pleomorphic Adenoma (PA). The cytologic features of MECA overlap with other SG neoplasms including the more common benign entities like PA and myoepithelioma and can pose a diagnostic challenge.

Myoepitheliomas are rare salivary gland-type tumors. The tumors are divided into four histological subtypes (spindle cell, plasmacytoid, epithelioid, and clear cell) and two variants (reticular and mucinous). A myoepithelioma of the mucinous variant, also referred to as mucinous or secretory myoepithelioma, is a novel variant of myoepithelioma characterized by the presence of extracellular mucin.

Myoepithelial tumors of the soft tissue and bone occurring in patients 21 years of age and younger are rare, and their clinicopathologic features remain incompletely understood. We studied a well-characterized series of 40 such tumors. Cases were retrieved from our archives for the period 2009-2022 and re-reviewed.
