Ann Saudi Med 2012; 32(6): 642-645 DOI: 10.5144/0256-4947.2012.01.7.1530 We describe an unusual case of trichilemmal carcinoma accompanied by a large horn formation in a 79-year-old man who presented with a brown tumor mass including a 15-cm-long horn on the vertex for one and a half years. Two months after the surgical removal of the primary tumor, the tumor recurred with a dimension 10x8x8 cm. The tumor was then excised again and the wound was covered using skin from the patient's back. Microscopically, the tumor showed histology consistent with trichilem-mal carcinoma. After 2 years, the patient had not shown any recurrence or metastases. We highlight the features that distinguish trichilemmal carcinoma from the other malignant tumors, such as squamous cell carcinoma, basal cell carcinoma, nodular melanoma, or keratoacanthoma.
