Desmoid Tumour of the Brachial Plexus

الملخص EN

Desmoid tumours of the brachial plexus are rare and may occur in extra-abdominal sites.

The tumours are of fibroblastic origin and, although benign, are locally aggressive.

Their relationship to critical neurovascular structures in their anatomic locations presents a challenge to the operating surgeons trying to adhere to the principles of surgery.

Surprisingly little neurosurgical literature exists which was devoted to this topic despite the challenge these lesions present in surgery both at surgery and in choosing adjuvant therapies.

We report a case of a large brachial plexus tumour in a patient which was diagnosed radiologically and histopathologically and the patient underwent surgical excision with good outcome.

Desmoid tumours histologically are benign and are usually composed of proliferating, benign fibroblasts in an abundant matrix of collagen.

They do not transform into malignant tumours or metastasize.

Surgery is the mainstay of treatment; however, adjuvant radiation and chemotherapy remain controversial.
