title: Trabecular carcinoma of the skin: a case report.
abstract: A case of trabecular carcinoma of the skin in a 62 year old Caucasian male is reported. The lesions occurred on the face, ear, chest, abdominal wall, and the upper extremity over a period of four years. At the light microscopic level the lesions were confused with metastatic carcinoma, lymphoma, and adult neuroblastoma. Ultrastructural study revealed the presence of not only neurosecretory granules but also premelanosomes in the tumor cells.
