title: [Scintigraphy with thallium chloride in a case of clear cell sarcoma of the tendons and aponeurosis].
abstract: Clear cell sarcoma of the soft parts (CCSSP) is a rare and highly malignant tumor. This is a case report of a 31 years old woman who presented with a tumor in the internal face of left thigh. The tumor biopsy was suggestive of a possible malignant tumor of the peripheral nerve sheath (malignant schwannoma). Biochemical analyses, computed tomography and magnetic resonance were performed and reported a sarcoma of soft parts (CCSSP) without abnormal inguinal lymph nodes. With this diagnostic suspicion, the patient was sent to the Nuclear Medicine Service of our center where a 201Thallium scintigraphy study was performed. In this study, it showed the primary tumor together with a hot spot in the homolateral inguinal region, suggestive of the presence of a metastastic lymph node. This finding would change the surgical attitude in the patient, including inguinal lymphadenectomy. The post-surgical histological study confirmed a clear cell sarcoma of soft parts (CCSSP) with a metastatic inguinal lymph node.
