One-stage combined approach en bloc vertebrectomy for primary Ewing's sarcoma of mobile spine in an adult patient: 3 years following aggressive surgery for a rare entity.

Key Clinical Message: Currently, there is no consensus on the optimal management of nonmetastatic Ewing's sarcoma of the mobile spine. However, associated to chemotherapy, aggressive surgery with en bloc wide resection seems to improve local control and survival. Abstract: Primary Ewing's sarcoma (EWS) of non-sacral spine is extremely rare, especially in middle-age. Therapeutic strategy aims: to large tumor resection, to provide spine stability and to avoid recurrence through chemo and radiotherapy. We report a case of thoracic spine EWS in an adult treated by combined approach en bloc vertebrectomy.

Primary giant hydatid cyst of the thigh: An unusual location.

Key Clinical Message: Primary hydatid cyst of the thigh is a rare condition requiring prompt recognition and accurate diagnosis for timely management and prevention of complications. Abstract: Muscular hydatid cysts are rare, with a frequency ranging from 1% to 5% even in endemic areas. The clinical presentation of muscular hydatidosis is typically subtle and lacks specific features, frequently resulting in delayed diagnosis. Herein, the authors describe a case of a primary hydatid cyst located in the thigh.

Bone metastases from renal cell carcinoma: 4 years after aggressive surgeries and anti-angiogenic therapy.

Management of bone metastases from renal cell carcinoma (RCC) has significantly changed after the era of targeted therapy that improved the overall survival (OS). Surgical decision-making remains a subject of controversy. We report a case of pelvic bone metastasis from RCC, 2 months after nephrectomy and surgery of a revealing clavicular metastasis.

A rare soft tissue tumor of the big toe: Superficial acral fibromyxoma.

Superficial acral fibromyxoma (SAF) is a rare and benign soft tissue tumor that has a predilection to develop in acral sites. Its treatment is surgical excision. Follow-up is recommended due to the risk of recurrence. The purpose of this case is to raise awareness of this recently described neoplasm.
