title: Metastatic trichomatricial carcinoma.
abstract: Trichomatricial carcinoma has been recently recognized as a rare malignant variant of pilomatricoma with a potential for local recurrence and, rarely, for distant metastases. We describe such a tumor in a 52-year-old man who developed local recurrence and axillary lymph node metastases within six months of local excision, followed by bilateral pulmonary metastases and 2 1/2 years later by death due to disseminated tumor. This, to our knowledge, is the second reported case of metastasizing trichomatricial carcinoma.
