Cystic panfolliculoma of the conchal bowl
Abstract
Panfolliculomas are rare, benign follicular neoplasms showing differentiation toward all components of the hair follicle. Cystic panfolliculoma (CPF), a histologic variant, is uniquely characterized by epidermal invagination. This lesion is uncommon, with fewer than 25 cases reported in the literature. Clinically and histologically, it can mimic other tumors, including basal cell carcinoma and trichoblastoma, complicating diagnosis. We describe a case of CPF arising in the right conchal bowl of an 84-year-old man, along with a brief review of similar cases.
