Abstract
Aim
Bumps and lumps of the hand are a common cause for consultation in general practice. However not all of these lesions are of true neoplastic nature and malignant tumours are a rarity in this location.
Method
The records of all tumours of the hand and wrist treated surgically at our institution in the period 1994 to 2009 were reviewed. Because of their non-neoplastic nature typical lesions of the hand such as ganglion cysts or palmar fibromatosis and the like were not included in this study. Histological entity, location, radiographic and clinical findings were analysed; malignant tumours were followed up by X-ray and MRI.
Results
Out of 142 cases which were further investigated, there were 86 bone tumours and 56 soft tissue lesions. The mean age was 41 years (range 8 to 85), there were 57 male and 85 female patients.122 cases (86%) were benign lesions, 71 cases located in the bone and 52 cases in the soft tissue respectively. There were twenty malignant lesions, sixteen of which were bone tumours; the most common being chondrosarcoma (11), followed by metastases (3) and osteosarcoma (2). The group of malignant soft tissue tumours (4) was comprised of synovial sarcoma (2), Ewing sarcoma (1) and extraosseus myxoid chondrosarcoma (1).
Out of 52 benign soft tissue tumours, pigmented villonodular synovitis (32), haemangioma (6) and lipomatous tumours (6) have been the most frequent entities. Chondroma (48), osteoid-osteoma (4) and giant cell tumour (3) were the most common benign bone tumours.
Conclusion
Knowledge of tumour prevalence under consideration of the patient's age and location of the tumour is an important prerequisite for identifying neoplastic lesions of the hand.
