Abstract

A 7-year-old boy underwent uncomplicated laparoscopic appendectomy for acute appendicitis. Incidentally, he was found to have a spindle cell tumor with CD117 immunopositivity, consistent with gastrointestinal stromal tumor (GIST) in the appendix. Although commonly reported in adults, pediatric GISTs are rare gastrointestinal malignancies that occur in only 1.4-2.7 % of children and adolescents [1]. Due to the paucity of reports, data are insufficient to adequately characterize tumor behavior, recurrence, and survival. We present the first case of pediatric GIST in the appendix. In addition, a review of the literature for CD117 confirmed pediatric GISTs was conducted to summarize its clinical features and current treatment options.
