Abstract PDF: We report a case about successful surgical treatment of a granular cell tumor in the ascending colon. A 36-year-old man underwent screening colonoscopy. An endoscopic examination revealed a 10-mm yellowish and hemispheric mass in the ascending colon, and lower endoscopic ultrasonography revealed a hypoechoic-to-isoechoic mass invaded the submucosal layer. The mass was suspected to be a colonic carcinoid tumor. Based on the preoperative evaluation, endoscopic complete resection was considered difficult. Therefore, the lesion was removed via laparoscopic right hemicolectomy. Histological examination revealed that the tumor consisted of nests of polygonal cells with abundant granular eosinophilic cytoplasm. Immunohistochemical staining revealed diffuse positivity for S100 and CD68. Therefore, the tumor was diagnosed as a granular cell tumor. We suggest that surgical resection should be considered if it is located in the thin-walled ascending colon prone to perforation, difficult to rule out malignant tumor due to submucosal invasion, or to remove endoscopically.

Abstract PDF

Small intestinal malignant tumor accounts for about 3% of all malignant tumors in the gastrointestinal tract, among which 13% are leiomyosarcoma (LMS). In addition, epithelioid LMS is of very rare occurrence. As small intestinal malignant tumors are initially asymptomatic and nonspecific, diagnosis is often delayed, and this can lead to large tumor at the time of detection and lead to intussusception. We observed ileocolonic intussusception in an 80-year-old male patient who was admitted to the hospital with a complaint of abdominal pain and palpable mass on right lower quadrant. The laparoscopic ileocecectomy was performed by the emergency operation because of obstruction. The pathologic examination revealed that the epithelioid LMS developed in the terminal ileum was the leading point of intussusception. To the best of our knowledge, laparoscopic surgery for ileocolonic intussusception with epithelioid LMS has not yet been reported.
