Cutaneous sarcoidosis showing multiple papular eruptions with keratotic plugs

A 26-year-old woman developed 249 discrete papules on her lower extremities. Twenty-three of them had keratotic plugs. Histologic examination demonstrated granulomatous foci consisting of epithelioid cells and a epidermal invagination which was disrupted at the base and lateral sites. This invagination was considered to represent transepithelial elimination.
