Trichostasis spinulosa arising within syringoma.
A forty-eight-year-old man presented with multiple pinhead to rice-sized papules on the face. Histopathologic examination showed a typical syringoma and dilated hair follicles containing several vellus hairs in the middle of a fibrotic stroma. We discuss the possible pathomechanism between these two conditions in the same lesion.
