Abstract

Solitary circumscribed neuroma (SCN) also called Palisaded encapsulated neuroma (PEN) is a benign neural tumour, which usually present as skin coloured papule or nodule on face. Clinically, often it mimics Intradermal melanocytic nevus or cutaneous neurofibroma. Microscopically it mimics a neurofibroma and schwannoma, especially when there is nuclear palisading or even a cutaneous leiomyoma if there are epithelioid cells rather than the usual spindle cells. Here we are reporting two cases of SCN, over the face with characteristic histomorphological findings of Intratumoral clefts
