Giant Malignant Schwannoma in the Right Thoracic Limb: Case Report

Introduction: Tumors of the sheath of the peripheral nerves, also known as schwannomas, mainly benign. The malignancy of these is very rare and there are few cases reported in the literature.

Clinical case: A 62-year-old male with a diagnosis of ulcerated malignant schwannoma in the distal third of the posterior aspect of the right thoracic limb who attended the oncosurgery service. The CT scan reported a large solid tumor, predominantly hypodense, with a probable origin dependent on the poorly defined triceps brachii muscle. Surgical removal was performed with two centimeters of perilesional margins, performing primary closure with drain placement.

Conclusion: Surgical treatment of total surgical removal with adequate margin coverage is the treatment of choice as a protective factor in survival in this type of tumor..
