Abstract
Objective: To report a rare occurrence of giant, solitary, cystic, intramuscular plexiform neurofibroma in the thigh. Case Report: A 45-year-old architect presented with a 5-year history of painless, progressively enlarging soft tissue mass in the right thigh, which was diagnosed on histology as cystic plexiform neurofibroma after excision biopsy. Conclusion: A plexiform neurofibroma should be considered in the differentials of a solitary cystic mass in the thigh even in the absence of usual manifestations of Neurofibromatosis.
Highlights
According to Stedman’s Medical Dictionary, a plexiform neurofibroma (PN) is a type of neurofibroma representing an anomaly rather than a true neoplasm in which the proliferation of all elements of the nerve occur from the nerve sheath thereby resulting in an irregularly thickened, distorted tortuous structure (Stedman 2006)
A plexiform neurofibroma should be considered in the differentials of a solitary cystic mass in the thigh even in the absence of usual manifestations of Neurofibromatosis
We present this patient with PN because of its giant size, cystic nature, in a rare intramuscular location and not associated with Neurofibromatosis-1
