TRICHILEMMAL CYST OF THE THIRD FINGERTIP: A CASE REPORT

Abstract

Introduction: Trichilemmal cysts (TCs) are common skin lesions that occur in hairy areas. A TC involving a fingertip has not been previously described in the literature. We herein report a case of a TC occupying a fingertip region. Case presentation: A 43-year-old woman presented with a 1.5 × 1.5 cm nodular lesion on the third fingertip. The lesion was completely excised, and histopathological examination revealed a TC. Conclusion: TCs may involve atypical locations, such as fingertips, where there are no hair follicles. After surgical excision, a careful histopathological examination should be performed to differentiate TCs from proliferating pilar tumors.
