متن کاملA Cutaneous Myoepithelial Carcinoma Arising in a Papillary Eccrine Adenoma
Benign and malignant neoplasm of myoepithelial cells comprise a rare but well-characterized group of tumors in the salivary glands, breasts, and soft tissues. Histopathologically, myoepitheliomas show solid, reticular, trabecular architecture and myxoid or hyaline stroma, and are composed of round/epithelioid or spindle cells.
