Fungating Growth of Squamous Cell Carcinoma in Long-Standing Meningocele.

Squamous cell carcinoma is known to occur as a serious complication of chronic burns, scars, and ulcers, but very rarely has it been reported to occur in a long-neglected meningocele. The authors wish to present the case of a 21-year-old man who presented to us when a previously asymptomatic meningocele developed a squamous cell carcinoma on the meningocele sac. The squamous cell carcinoma was excised in toto, followed by excision of the redundant meningocele sac. The neural placode was closed and dural closure done with an artificial dural patch. Reconstruction of the defect thus created was performed by a lumbar perforator-based reverse latissimus dorsi myocutaneous flap. The patient did not develop any postoperative neurological deficits and made an uneventful recovery in the postoperative period. He received adjuvant radiation therapy and is doing well at 4 months' follow-up.
