Abstract

A case of sebaceous carcinoma was reported. The patient was a 59-year-old man who had a reddish nodule on his left hypochondriac region. Histopathologically, the tumor was non-capsulated but relatively circumscribed reaching the subcutaneous tissue. It consisted of variably sized lobules of undifferentiated cells and sebaceous cells with abundant foamy vacuolated cytoplasm. This is the first case which has occurred on the chest or abdomen in Japan.
