Abstract

Cutaneous neurofibromas are benign peripheral nerve sheath tumors confined to the dermis and are commonly encountered either in association with neurofibromatosis type 1 or as solitary sporadic lesions. They demonstrate considerable clinical polymorphism and may present as sessile, globular, or pedunculated lesions. We report a 47-year-old man who presented with a painless, progressively enlarging pedunculated mass over the posterior aspect of the left leg for two years. There were no clinically evident features suggestive of neurofibromatosis type 1. Imaging revealed a well-defined superficial soft-tissue lesion with a discrete vascular stalk and no deep extension. Complete surgical excision was performed. Histopathological examination demonstrated an unencapsulated dermal tumor composed of spindle-shaped cells with elongated, wavy nuclei embedded in a mildly myxoid stroma, consistent with cutaneous neurofibroma. This case illustrates a solitary pedunculated presentation of localized cutaneous neurofibroma in the lower limb and highlights the value of multimodal imaging and histopathological correlation in the evaluation of superficial polypoid lesions. Complete excision is generally definitive treatment, with no recurrence observed at six-month follow-up in the present case.
