Epitheloid Leiomyosarcoma of the Jejunum Presenting with Intussusception in a Young Adult Male: A Case Report

摘要

A 27-year-old male presented with intestinal obstruction due to a jejuno-jejunal intussusception, 23 years after a childhood nasopharyngeal carcinoma. He was successfully treated for the latter by radiotherapy but subsequently required a mandibuloplasty for presumably facial hypoplasia sequel to the radiotherapy. The present intussusception was resected with wide margins revealing a partly haemorrhagic, polypoid and sessile jejunal tumour measuring 7.7 × 3.5 × 2.6 cm. Microscopy with extensive immunohistochemical studies revealed a relatively rare and highly malignant epitheloid leiomyosarcoma arising from the muscularis propria with extension to the mucosa and serosa. No metastases were found and post-operative follow-up has so far been uneventful. The present case of a malignant tumour presenting as an intussusception in a young adult, was unrelated to a childhood malignant tumour in the same patient. The former was successfully treated by a wide excision in support of the advocated surgical approach to adult intussusception.
