We report the case of a 33-year-old female who presented with a painful, rapidly growing mass on her left dorsal forearm. Physical examination revealed a 2 cm firm, well-demarcated, non-erythematous nodule beneath the skin, with an initial diagnosis of lipoma. Upon removal, the mass was found to be intramuscular beneath the antebrachial fascia. The histopathology confirmed a benign giant cell tumor of soft tissue (GCT-ST). The patient was informed of the potential risk of recurrence, and regular follow-up was recommended. At the last follow-up, no clinical evidence of recurrence was noted. This report highlights a rare case of an intramuscular soft tissue GCT at an exceptional location, the forearm.
我们报告了一例33岁女性病例,该患者左前臂背侧出现一个疼痛且生长迅速的肿块。体格检查发现皮下有一个2厘米大小、质地坚硬、边界清晰、无红斑的结节,初步诊断为脂肪瘤。切除后发现肿块位于前臂筋膜下的肌肉内。组织病理学证实为良性软组织巨细胞瘤(GCT-ST)。已告知患者复发的潜在风险,并建议定期随访。在最后一次随访时,未发现复发的临床证据。本报告强调了在前臂这一特殊部位发生的肌肉内软组织GCT的罕见病例。
