title: [Umbilical Hernia Complicated by Gastrointestinal Stromal Tumor of the Small Intestine - A Case Report].
abstract: Intraabdominal tumors can cause umbilical hernia and may lead to serious consequences, such as incarcerated or necrotized intestine. However, little information is available concerning how the location and characteristics of tumors may affect the process of umbilical hernia development. A 46-year-old Japanese man presented at the department of surgery with abdominal pain and abdominal retention, which appeared on the day of presentation and 4 years before the presentation, respectively. Abdominal computed tomography revealed a suspected gastrointestinal stromal tumor(GIST)and an umbilical hernia close to the tumor, both of which were clinically diagnosed. Surgical tumor resection and hernia repair were conducted successfully. The patient was pathologically diagnosed with high-risk GIST. Adjuvant therapy with imatinib was administered with no recurrence as of 1 year post-surgery. This is a case of GIST complicated by umbilical hernia. Small solid tumors may cause umbilical hernia if they are in close proximity to vulnerable parts of the abdominal wall.
