Abstract

Isolated cutaneous swelling can have varied etiologies. The clinical diagnosis is usually difficult, and a correct diagnosis always requires a pathological examination. Hereby, we report a case of linear keloidal morphea on the neck of an 18-year-old male who presented with an asymptomatic, firm lesion for 6 months. Histopathological examination was consistent with morphea. This case highlights the uncommon form of morphea in an unusual location, which can be misdiagnosed for numerous neoplastic conditions and for which simple histopathological evaluation can clinch the diagnosis.
