Tenosynovial giant cell tumor, localized type, with recurrence, and lung metastases: A case report

Tenosynovial Giant Cell Tumors (TSGCT) are the second most frequent benign soft tissue tumor in the hand and wrist after ganglion cysts. The tumor arises from joint synovia and tendon sheaths. It is divided into 2 categories: localized and diffuse type. The well-circumscribed localized type usually responds nicely to single excision surgery. The diffuse type, on the other hand, has a proclivity for becoming an aggressive lesion. We reported a case of a 56-year-old woman who was experiencing shortness of breath as a result of lung metastases. A TSGCT, localized type, was found after radiology, and histology examination of the re-excised surgical lesion was done. This rare case demonstrates the possibility of lung metastases from tenosynovial giant cell tumor, localized type.
