Intestinal leiomyosarcomas are exceedingly rare in immunologically intact children, except during infancy. While leiomyosarcomas account for less than 2% of all soft tissue tumors in childhood, they are the second most frequent malignancy in children with the acquired immunodeficiency syndrome (AIDS). In this cohort they are often located in unusual sites for primary soft tissue tumors. This report describes a young girl with advanced AIDS, referred for evaluation of abdominal pain, hematochezia, and wasting syndrome. Colonoscopy revealed two 1- to 2-cm submucosal nodules with central umbilication. Repeat colonoscopy 18 months later revealed no changes in these lesions. Biopsy revealed a submucosal spindle-cell lesion, with necrosis and cellular atypia. Initially it was characterized as a partially excised low-grade leiomyosarcoma. However, the final consensus diagnosis was smooth muscle tumor of uncertain malignant potential. Because of her advanced AIDS, there was no attempt at surgical resection or chemotherapy. Thirty-six months after initial referral, she remains alive without radiographic or clinical evidence of local extension or metastases. Additional data are required to determine the long-term outcome of these indolent submucosal tumors in the digestive tracts of children with AIDS. |
