A Giant Solitary Trichoepithelioma Originating from the Auricle

“…GSTs have a close histopathologic and clinical resemblance to keratotic basal cell carcinoma. Histopathologically, the tumor consists of basaloid epithelial cell islands, abortive hair follicle structures characterized by follicular differentiation, and keratinous cystic structures …”

“…The solitary types do not show hereditary transition. Hereditary trichoepitheliomas are seen in younger people with multiple millimetrical nodules . In this article, we describe a GST originating from the auricle and evaluate the approach to its management.…”
