LARGE PLEXIFORM NEUROFIBROMA OF THE SACRO-GLUTEAL REGION – A RARE CASE REPORT

Abstract

Plexiform neurobroma is a rare benign nerve sheath tumor that develops in the perineurium and is often considered pathognomonic of neurobromatosis type 1 (NF1 or von Recklinghausen disease). They occur most frequently in the craniomaxillofacial region, rarely on back and extremities. These lesions are highly vascular and there is 15-20% potential for malignant transformation. Here, we present a 26-year-old female with neurobromatosis all over her body, but with a large plexiform neurobroma in the sacral region which was causing difculty in sitting and lying supine as well as disgurement of the gluteal region. Surgical excision with primary closure of the swelling was done. Histopathology ndings were consistent with neurobromatosis.
