Case Report
In December 2008, a 52-year-old, right hand–dominant woman was referred to our hospital reporting pain and tenderness in the left trapeziometacarpal joint. She initially noticed discomfort with no major trauma in 2006. The symptom had increased over time, changing to pain and subsequent difficulty of grasp motion.

Discussion
Osteochondroma of the carpal is extremely rare. Our literature search revealed 21 cases of osteochondroma occurring in carpals, including 15 cases of scaphoid,4, 5, 6, 8 3 of capitates,9, 11 and 1 each of lunate,12 hamate,13 and trapezium.14 Most osteochondromas develop in the scaphoid. Only 1 case of osteochondroma originating from the trapezium has been reported. The mean age of patients with carpal osteochondromas in previous reports was 50 years (range, 14–84 y). Complications have been

2017, International Journal of Surgery Case ReportsCitation Excerpt :Distal phalangeal tumors almost always arise subungually and cause nail deformity [2]. Tumors arising from the carpal bones may cause extensor tendon rupture [3], carpal tunnel syndrome [4], or pain [5]. In this paper, we present a rare case of a giant multi-lobed osteochondroma of the phalanx developing in an adult.
