The exact pathogenesis of<unk>  adenoma is not fully understood. Chromosomal abnormalities involving 8q12 and 12q15 have been described. The gross features of<unk>  adenoma are firm, well demarcated, encapsulated, and mobile. On microscopic histopathology they are a mixture of both epithelial cells and stromal matrix. The stromal matrix can be either hyaline, cartilaginous, myxoid. The epithelial components can be arranged into clumps, sheets or interlacing strands. On immunohistology these tumors are positive for S-100, GFAP, actin, keratin.
