Abstract

Systemic chemotherapy is a standard treatment for Stage IVc nasopharyngeal carcinoma (NPC). Stage IVc NPC patients with oligometastases have a better prognosis, and local therapy has an important role in further development of the disease. However, the efficacy of local therapy to the metastases in patients with multiple-site and/or multiple-organ metastases is limited due to the aggressive behavior of the tumor. We report a NPC case in a pediatric patient with repeated oligometastases involving the bone, liver and distant lymph nodes who achieved 10-year disease free status after initial chemotherapy and radiotherapy to all the metastases. This very rare case demonstrated that radiotherapy to oligometastatic lesions have a potential to cure repeated oligometastases which involved multiple-organ metastases in a pediatric NPC with stage IVc.

Abstract

Introduction: Diffuse-type tenosynovial giant cell tumor (D-TGCT), or pigmented villonodular synovitis, is a benign, but aggressive lesion, primarily involving large joints. The spine is rarely affected, with the involvement of the thoracic spine being particularly rare. Massive bone involvement associated with facet joints is a characteristic of spinal D-TGCT. Case Report: We report the case of a 26-year-old woman with D-TGCT in her first thoracic vertebral lamina. Computed tomography (CT) showed an osteolytic expansive lesion without the involvement of the facet joint. Magnetic resonance imaging (MRI)revealed a lesion with intermediate signal intensity on T1- and T2-weighted images. After computed tomographically guided biopsy, curettage was performed, and D-TGCTwas diagnosed. Conclusions: Features of CT and MRI suggested an aggressive bone lesion, and it was challenging to assume D-TGCT, particularly without the involvement of the facet joint.
