Abstract

Tenosynovial giant cell tumor (TGCT) is a rare type of neoplasm that may be locally aggressive but is most often benign and can be divided into two subtypes: localized and diffuse. It tends to develop in the joints, bursae, and tendon sheaths primarily in the digits of the hand and less commonly in the forefoot. This soft-tissue mass has many possible differential diagnoses, including lipoma, ganglion cyst, plantar fibroma, and various sarcomas; surgical excision is usually indicated to reach a definitive diagnosis and rule out malignancy. We report a rare case of a 30-year-old woman with atypical plantar hallucal pain and a palpable mass on the plantar lateral aspect of the left hallux. Surgical excision and histopathologic evaluation confirmed a TGCT of the left hallucal flexor tendon sheath. Although it bears clinical resemblance to several other soft-tissue masses, TGCT has numerous pathognomonic features evident with advanced imaging and histologic analysis that help the physician obtain an accurate diagnosis and proceed with appropriate treatment.

非典型表现的腱鞘巨细胞瘤位于舌侧屈肌腱鞘上:病例报告。
腱鞘巨细胞瘤(TGCT)是一种罕见的肿瘤,可能具有局部侵袭性,但多为良性,可分为两种亚型:局部型和弥漫型。它往往发生在关节、滑囊和腱鞘中,主要发生在手的指端,前足较少见。这种软组织肿块有许多可能的鉴别诊断,包括脂肪瘤、神经节囊肿、足底纤维瘤和各种肉瘤;通常需要进行手术切除以明确诊断并排除恶性肿瘤。我们报告了一例罕见病例,患者是一名 30 岁女性,患有非典型足底幻觉痛,左脚脚掌外侧可触及肿块。手术切除和组织病理学评估证实了左侧拇指屈肌腱鞘的 TGCT。虽然 TGCT 在临床上与其他几种软组织肿块相似,但通过先进的影像学和组织学分析,TGCT 有许多明显的病理特征,有助于医生获得准确的诊断并进行适当的治疗。
