Trichilemmal Carcinoma: A Rare Cutaneous Malignancy: A Report of Two Cases

BACKGROUND: Trichilemmal carcinoma is a rare cutaneous malignancy that usually occurs on the sun-exposed areas of older individuals. The lesion is usually solitary and may present as an exophytic or polypoid nodule that maybe hyperkeratotic with ulceration. OBJECTIVE: To present two cases of trichilemmal carcinoma, one occurring in a kidney transplantation patient. METHODS: Two case reports and a discussion of the rare carcinoma are presented. RESULTS: Both lesions were treated with Mohs micrographic surgery without sign of recurrence after several years. CONCLUSION: Trichilemmal carcinoma is a rare cutaneous malignancy that can be seen in both immunocompetent and immunosuppressed hosts. Mohs micrographic surgery should be considered among the surgical options to avoid a wide surgical excision in these patients.
