Pilomatrix carcinoma with subsequent pulmonary metastases: a case report

ABSTRACT

Pilomatrix carcinoma is the malignant counterpart of the pilomatrixoma which is a hamartoma of the hair matrix. It is a rare locally aggressive skin tumor with a great tendency for recurrence but its metastatic potential is limited. We report a pilomatrix carcinoma with proven metastases to the lung in a 51-year old man who was admitted to the hospital for respiratory symptoms such as productive cough with green colored sputum and halitosis since one year ago
