Alveolar soft-part sarcoma (ASPS) is a very rare malignant tumor, usually of the extremities, and is seen most often in adolescents and young adults. Surgical excision of the primary and pulmonary metastases has resulted in prolonged survival in some patients, but adjuvant radiation and/or chemotherapy are generally thought to be ineffective. The authors describe a 13-year-old patient with ASPS...

Alveolar soft part sarcoma (ASPS) is a rare malignant soft-tissue neoplasm of unknown histogenesis. The two main sites of occurrence are the lower extremities in adults and the head and neck in children. We report the first case of pleural ASPS occurring in a 58-yr-old man who presented with progressive dyspnea. A computed tomographic scan of the thorax revealed a large enhancing pleural mass w...

Alveolar soft part sarcoma is a rare tumour of unknown histogenesis. Although tumour growth is slow and often asymptomatic, vascular invasion and metastatic dissemination (especially to the brain and lung) take place early in the course of disease. Resection is the treatment of choice and could lead to complete remission. If complete resection is not possible, the prognosis of alveolar soft par...

INTRODUCTION Alveolar soft-part sarcomas are rare, slow-growing tumors that metastasize commonly via vascular routes to the lungs, bones, lymph nodes and brain, causing morbidity and mortality. To the best of our knowledge, this is the first case describing metastasis to the liver reported from Nigeria. CASE PRESENTATION A 57-year-old man of the Urhobo ethnic group of Nigeria presented with a...

Background. Alveolar soft part sarcomas (ASPS) of the head and neck are rare, aggressive soft-tissue malignancies. This study describes the clinical course and management of two patients presenting with ASPS in very rare head and neck locations, the larynx and parotid gland. Methods. We identified two patients presenting with ASPS of the head and neck and treated at the University of North Caro...

PURPOSE To evaluate the characteristics of highly malignant soft tissue sarcoma of the extremity with a delayed diagnosis. MATERIALS AND METHODS The clinical and radiological characteristics of 18 cases of highly malignant soft tissue sarcomas of the extremity with a delayed diagnosis were determined. RESULTS Ten men and eight women of mean age 44.8 years (range, 15-79 years) were included ...
