RESUMO
Giant cell tumour is a benign lesion classified as a fibrocystic tumour whose localization in Hoffa's fat pad is very rare. Clinical symptoms are insidious and non-specific causing a frequent confusion and delay in diagnosis therefore it should be distinguished radiologically from other similar conditions such as Hoffa´s disease and lipomas. We report a case of a 37-year-old patient, with no relevant history, who complained of a right knee pain for 5 years. Magnetic resonance imaging showed a small nodular mass in Hoffa's pad which was excised through a direct approach. Histologic examination of the specimen revealed a giant cell tenosynovial tumour. One year after surgery, the patient was asymptomatic with no local recurrence. The surgical removal of the tumour is the ideal treatment. The choice between open surgery and endoscopy depends on the site, size, and extent of the tumour.

Primary musculoskeletal echinococcosis is rare and accounts for 2-3% of the patients with hydatid disease. We report a case of giant primary hydatid cysts of the thigh and the gluteal region in an 82-year-old female, who presented with a painful multiple palpable mass. The diagnosis was confirmed by imaging and serology. Total resection was performed through an extended lateral approach of the thigh and intraoperative findings revealed infected giant hydatid cysts. The postoperative outcome was uneventful. Albendazole drug (400mg per day) was given for the next 3 months. At 6 months follow-up, the patient was satisfied with no complications or recurrence.
