Two cases of subcutaneous trichoblastoma.

This report concerns two Japanese women, 54 and 53 years old, with trichoblastoma. Histopathologically, these neoplasms were mainly composed of follicular germinative cells with fibrotic stroma. One of them was a giant lesion, but the other was small. Because both lesions were located in the subcutis, we termed them subcutaneous trichoblastoma.
