BackgroundSignet-ring cell adenocarcinoma of the colon is well-recognized in adult patients who are extremely rare and not well-documented in children. Our study aims to raise awareness about this rare disease and its long-term outcomes.MethodsWe retrospectively evaluated patients with signet-ring cell colon adenocarcinoma.ResultsSix patients, three boys and three girls, with a mean age of 14.83 (range, 13-17 years), presented with signs of intesti-nal obstruction and were diagnosed with signet-ring cell colon adenocarcinoma. All patients had air-fluid levels on abdominal X-ray. Abdominal ultrasonography of all patients revealed subileus. Abdominal computed tomography was performed in five patients, and pre-operative colonoscopy was conducted in two patients before the emergency intervention. All of the patients underwent emergent exploratory laparotomy with the preliminary diagnosis of acute abdomen. In two patients, debulking surgery followed by a stoma was performed. The remaining four patients were treated with anastomosis following intestinal resection. All girls had metastases on the ovary. One of the patients died due to the burden of multiple metastases in the early period, and three died in the sixth post-operative year. We have been following the remaining two patients since then.ConclusionAlthough signet-ring cell carcinomas (SRCCs) are rare, they should be considered in the differential diagnosis of acute abdomen and intestinal obstruction in pediatric patients. Despite early diagnosis and treatment, SRCC has a poor prognosis in the pediatric population.
