RESUMO
<p><b>INTRODUCTION</b>Hand tumours are frequently encountered in clinical practice. A list of differential diagnoses of the most common hand tumours based on anatomical location would be helpful for clinicians. We aimed to determine the anatomical distribution of hand tumours seen at a hand surgery practice in Singapore.</p><p><b>METHODS</b>The medical records of 50 men and 65 women (mean age 41.7 [range 17-74] years) who underwent excision of hand tumours between 1 June 2010 and 31 December 2012 were reviewed. The histological diagnoses and anatomical locations of the tumours were analysed. The locations were divided into three main groups: (a) distal to the metacarpophalangeal joints (MCPJs); (b) between the MCPJs and carpometacarpal joints (CMCJs); and (c) between the CMCJs and the radiocarpal joint (RCJ).</p><p><b>RESULTS</b>Overall, the most common tumours excised from the hand were ganglions (n = 66/116, 56.9%) and giant cell tumours of the tendon sheath (GCTTSs; n = 11/116, 9.5%). However, distal to the MCPJs, GCTTSs (n = 11/39, 28.2%) were more common than ganglions (n = 7/39, 17.9%). Most of the ganglions (n = 59/66, 89.4%) arose from between the CMCJs and RCJ.</p><p><b>CONCLUSION</b>Most hand tumours were benign. Ganglions were the most common tumours between the CMCJs and RCJ, while GCTTSs were the most common tumours distal to the MCPJs.</p>
RESUMO
El tumor de células gigantes u osteoclastoma es una lesión benigna, aunque con comportamiento agresivo, puesto de manifiesto por la posibilidad de recidivar, invadir estructuras aledañas y vasculares y posibilidad de desarrollar metástasis. Sin embargo, no responde a ningún tratamiento sistémico. Presentamos el caso de una mujer joven con varias recaídas locales de un tumor de células gigantes de origen costovertebral, con metástasis pulmonar única contralateral, y su tratamiento.
The giant cell tumour is a benign condition, but with aggressivebehavior, as evidence by the ability to recur, presentvascular invasion and possibility of metastasis. There isno role to systemic treatment for these tumours. We reportthe case of a young woman with several local relapses ofgiant cell tumour, with contralateral lung metastases andits treatment.
