“…Schwannomas most often affect the peripheral nerves. An exceptional location in axillary nerves was reported [6]. Multiple malignant nerve tumors occur mainly in the context of neurofibromatosis.…”

Objective: To report cases of armpit tumors in a retrospective study from 2010, January to 2015, December, to determine their diagnostic, therapeutic and prognosis aspect at Joliot Curie Cancer Center in Dakar.Results: It was about 8 cases of axillary tumors with a sex ratio of 1 and a mean age of 48 years. The consultation delay was of 2 years. Histology showed 1 high-grade nerve tumor, 1malignant schwannoma, 1 undifferentiated sarcoma, 1 Non-Hodgkin Lymphoma in a man and 2 carcinomas with unknown primary. In 2 patients, we found 2 infiltrating ductal carcinomas of axillary breast. Surgical treatment consisted of 3 surgical resections, 2 disarticulations of the shoulder. Follow-up was marked by 1 lymphedema after resection in 1 patient and a survival rate of 25% after 16 months of follow up. Conclusion:Axillary tumors are rare. Histological types are various. Surgery is the main treatment. Prognosis is improved by chemotherapy and radiation therapy for relative lesions.

“…In our patients, none of the tumours were located in musculocutaneous or axillary nerve. The latter location is a subject of casuistic reports [ 40 ]. Out of rare schwannoma locations in our study, we wish to highlight 2 cases of tumours located in medial cutaneous nerve of the arm.…”

Schwannomas are benign neoplasms derived from Schwann cells. In this work, we present our experience in operative management of schwannomas and analyse results of treatment. Clinical material consisted of 34 patients, in whom 44 schwannomas located in extremities were excised between 1985 and 2013. Thirty-five tumours originated from major peripheral nerves and 9 from small nerve branches. Postoperatively, in the first group of tumours, pain resolved in 100%, paresthesias in 83.3%, and Hoffmann-Tinel sign in 91.6% of the patients. Improvement in motor function was noted in 28.5% of the cases, in sensory function: complete in 70%, and partial in 15%. The most frequently affected major peripheral nerves were the ulnar (11 tumours) and median (5 tumours) nerves. Schwannomas originating from small nerve branches were removed without identification of the site of origin. After their resection, definitive healing was achieved. Conclusions. (1) Schwannomas located in extremities arise predominantly from major peripheral nerves, most commonly the ulnar and median nerves. (2) Gradual tumour growth causes exacerbation of compression neuropathy, creating an indication for surgery. (3) In most cases, improvement in peripheral nerve function after excision of schwannoma is achieved. (4) The risk of new permanent postoperative neurological deficits is low.

“…Firstly, this location of schwannoma is extremely rare in clinical practice. In the upper limb, these tumours are most commonly located in the ulnar, median and radial nerves, being significantly rarer in the musculocutaneous and axillary nerves [1,3,5,6,18]. In our For this reason, dysfunction of the medial cutaneous nerve of the arm does not cause evident discomfort in patients, in contrast to impairment of function of other nerves [2,16,20].…”
