Giant parosteal lipoma of thigh: A case report and review of the literature.

introduction and importanceParosteal lipoma is an uncommon benign tumor that can arise in various parts of the body. Giant parosteal lipomas are particularly rare and may compress or interfere with adjacent structures. Effective management typically involves surgical removal, with a thorough evaluation to exclude the possibility of malignancy. CASE PRESENTATION: We describe a case of a patient presenting with a soft tissue mass in the thigh measuring 10 cm × 14 cm × 26 cm and weighing 1300 g. MRI findings were suggestive of a parosteal lipoma. Wide excision of the tumor was performed using an anterior thigh approach. Histopathological examination confirmed the diagnosis of parosteal lipoma. The postoperative course was uneventful, with no complications or local recurrence observed. CLINICAL DISCUSSION: Most lipomas are asymptomatic; however, in some cases, they can affect nearby structures, potentially leading to compression syndromes. MRI is the preferred imaging technique for evaluating large soft tissue tumors with suspected malignancy. It plays a crucial role in distinguishing between differential diagnoses and facilitating treatment planning. Surgery is recommended for tumors that are large, symptomatic, compress vital structures like nerves or blood vessels, or are suspected to be malignant. Performing a wide tumor excision is crucial to reduce the likelihood of recurrence.

conclusionMalignancy should be carefully ruled out in diagnosing giant parosteal lipoma. MRI plays a crucial role in distinguishing between potential diagnoses, and aiding in surgical planning. Complete tumor excision through wide resection is the treatment of choice for this lesion.
