Intraosseous phalangeal growth of giant cell tumor of the tendon sheath (GCTTS) is an uncommon manifestation of this tumor, but it is well known because of its potentially aggressive local growth. This article details the findings of 2 cases of previously unreported intraosseous metacarpal involvement of GCTTS. Differential diagnosis of a metacarpal lesion with decreased radiodensity on radiographs should include GCTTS.
腱鞘巨细胞瘤（GCTTS）的骨内指骨生长是该肿瘤一种不常见的表现形式，但因其具有潜在侵袭性的局部生长而为人熟知。本文详细介绍了2例此前未报道的GCTTS累及掌骨骨内的病例。X线片上表现为掌骨病变且放射密度降低时，其鉴别诊断应包括GCTTS。
