Abstract

A rare soft tissue tumour--chordoid sarcoma of the thigh--in a 52-year-old woman is described. The tumour has a specific histologic structure and resembles a true chordoma. The most frequent site of chordoid sarcoma is the limb soft tissue that is in a direct link with fasciae, tendon sheaths and synovial membranes.

Proton radiation therapy for clivus chordoma--case report.

A 57-year-old male with clival chordoma developed severe hoarseness, dysphagia, and dysphonia 1 month after a second removal of the tumor. Magnetic resonance imaging demonstrated a mass 10 cm in diameter in the region of the middle clivus enhanced inhomogeneously by gadolinium-diethylenetriaminepentaacetic acid, and a defect in the skull base. There was evidence of compression of the anterior surface of the pons. He received proton irradiation employing a pair of parallel opposed lateral proton beams. The dose aimed at the tumor mass was 75.5 Gy, to the pharyngeal wall less than 38 Gy, and to the anterior portion of the pons less than 30 Gy. Time dose and fractionation factor was calculated at 148. Thirty-one months following treatment, he was free of clinical neurological sequelae. Proton therapy should be considered in treatment planning following initial surgical removal or for inoperable clivus chordoma.
