A 52-year-old man presented with multiple, skin-colored to hyperpigmented, smooth surfaced, firm, papules, and nodules of size varying from 2 to 8 mm over the periocular area, perioral area, dorsum of nose, and bilateral nasolabial folds [Figure 1]. His daughter had fewer and smaller, but similar, lesions on her face. Based on the clinical morphology, family history and histopathological findings, a diagnosis of trichoepithelioma was made. Trichoepithelioma is a benign appendageal proliferation of cells of follicular germinative differentiation.[1] The familial variant is inherited in an autosomal dominant pattern with decreased expression and penetrance in males.
