ABSTRACT
Introduction: Giant cell tumor of tendon sheath (GCTTS), also known as tenosynovial giant cell tumor or pigmented villonodular tenosynovitis, is a rare benign soft-tissue tumor with an unclear cause. It is the second most frequent soft-tissue tumor in the hand after ganglion cyst. Case Report: We described a female patient, age 19, who has had a 3 cm × 2 cm firm swelling on the palmer aspect of the right second metacarpal region for 7 years. The bulge developed spontaneously and moved quite slowly. It is required to do a histological and radiographic evaluation to determine whether or not to pursue additional treatment. Excision surgery was done, and the tumor was entirely removed. According to histopathology, this mass was compatible with GCTTS without being malignant. Conclusion: It is an uncommon instance of GCTTS at the hand, to sum up. The tumor should be entirely excised due to its high risk of recurrence to lower the likelihood of recurrence and restore hand function.
ABSTRACT
Introduction: Among all the primary bone tumors and all the type of lipomas, parosteal lipomas stand for <0.1% and 0.3%, respectively, which mostly consists of fully developed adipose tissue with or without a bony component. Patients with this tumor usually have bony lesions (59.2%), necessitating a differential diagnosis of malignant tumors. Case Report: Here, we analyze a case report of a 9-year-old boy, who developed a parosteal lipoma in the distal femur. A massive, well-defined, lobulated, mostly fat-intensity lesion of 10 cm by 6 cm by 8 cm was seen on an magnetic resonance imaging scan of the right distal femur. After the lump was removed, the pathologically reveals a parosteal lipoma without any malignant changes. Conclusion: Finally, it should be noted that parosteal lipomas are less common neoplasias with no known malignant potential. Since these tumors can be removed with mild impact to nearby structures, the lower limb's functionality is kept intact.
