Objectives/Interrogation: To report 18 case of patients with rare tumours in hand and forearm and review the related literature.

Methods: The sample consisted of 18 patients, who consulted for mass in hand and forearm who were taken to exeresis and the pathology report rare tumours for locating.

The sources of data for the literature review were obtained from Medline, Cochrane and Pubmed.

Results: 18 patients aged 8-74 years old, the tumours were:

• 1 endometrioma,
• 1 squamous cell carcinoma type Keratoacanthoma,
• 2 necrotizing synovitis,
• 1 Multiple Osteocondromas,
• 1 Schwannoma with metacarpal intraosseous osteochondroma,
• 3 atypical Schwannoma,
• 1 Nodular fascitis,
• 1 Keratoacanthoma type cutaneous horn,
• 1 cavernous hemangioma,
• 1 villonodular synovitis,
• 1 melanocytic lesions parallel ungual,
• 1 intravascular papillary endothelial hyperplasia,
• 1 aneurysmal bone cyst,
• 1 fibrokeratoma,
• 1 papillary digital adenocarcinoma.

Discussion and Conclusions: Because of rare occurrence of these tumours diagnostic and operative experience is relatively small.

There is also a few number of publications regarding strange tumours of hand and forearm. Therefore the aim of the study was present our experience in the surgical treatment of the unusual tumours of the hand and forearm basing on the material of 18 cases treated in the years 1999-2016.

In the literature there is no record of endometrioma in upper extremity, during our literature review we found only one case in lower limb. The present authors have 589 cases of resection tumours in 13 years, and these 18 cases represent 3% of them. Generally these rare tumours are average 2% of report in the literature review without significant experiences have resgistered.

Unusual tumours pathologies in hand and forearm are part of the differential diagnosis the hand surgeon must be present.
