Tenosynovial giant cell tumor is the common term used to describe a group of soft-tissue tumors that share a common etiologic link. These tumors are relatively infrequent in the foot and ankle, and occasionally they may be the cause of destruction of the adjacent bone structures. We report the imaging appearance and pathologic findings of two patients with localized tenosynovial giant cell tumor of the forefoot. Both of these patients underwent surgical gross total resection. However, one of the patients experienced a recurrence. Their clinical, radiologic, and pathologic features, with their treatment protocol, are summarized retrospectively, and related literature is reviewed in an attempt to enhance the understanding of these tumor lesions. Clinicians should perform a careful preoperative and postoperative examination and complete tumor surgical resection with the aim of reducing local recurrence.
Epidermoid cysts of the sole of the foot are rare lesions that must be differentiated from other, more common subcutaneous pathologic abnormalities located on the sole. Cases of epidermoid cysts that extend to the interosseous musculature are rarer still. We report the case of a giant epidermal cyst in a 64-year-old individual that extended to the intrinsic musculature of the third space of the right foot and that was diagnosed after fine-needle aspiration biopsy and subsequent cytologic study. Differential diagnosis of these lesions should be made with the support of additional imaging tests, and diagnostic confirmation should always be obtained after surgical removal and subsequent histopathologic study.
