The authors report a case of proliferating trichilemmal tumor and review the related literature. Although considered biologically benign, malignant proliferating trichilemmal tumor have been reported. The authors emphasize the importance of recognizing that the tumors can occur in individuals in their 20s and 30s, and that the tumors should be excised with a margin of normal tissue. Routine follow-up is recommended.
A 57-year-old Caucasian man presented for treatment of a biopsy-confirmed invasive squamous cell carcinoma on the right ear helix. Two stages of Mohs micrographic surgery were required to extirpate the tumor. The resulting surgical defect measured 2.2 Â 0.8 cm (Figure 1). The patient strongly preferred a single operative reconstruction. How would you reconstruct this defect?
