Abstract
Pilomatrix carcinoma is a rare locally aggressive hair-follicle tumor. We report a 54-year-old man who presented with a tumor in the left flank that was found by skin biopsy to be pilomatrix carcinoma. A contrast-enhanced computed tomographic scan of the chest, abdomen, and pelvis showed multiple small nodules in both lungs and lymphadenopathy in the abdomen. Video-assisted thoracoscopic biopsy of the lung lesions was consistent with metastatic pilomatrix carcinoma. After intravenous cisplatin and 5-fluorouracil, the skin, lung, and lymph node lesions shrank.
