| 2 | Anal canal gastrointestinal stromal tumors:Case report and literature review显示文摘Gastrointestinal stromal tumors(GIST)are an uncommon group of tumors of mesenchymal origin.GIST of the anal canal is extremely rare.At present,only 10cases of c-kit positive anal GIST have been reported in the literature.There is no widely accepted treatment approach for this neoplasia.Literature is sparse on imaging evaluation of anal canal GIST,usually described as a lesion in the intersphincteric space.We describe the case of a 73-year-old man with a mass in the anal canal,and no other symptoms.Endoanal ultrasound and magnetic resonance imaging showed a well circumscribed solid nodule in the intersphincteric space.The patient was treated by local excision.Gross pathological examination showed a 7 cm×3.5 cm×3cm mass,and histological examination showed a proliferation of spindle cells,with prominent nuclear palisading.The mitotic count was of 12 mitoses/50 HPF.The tumor was positive for KIT protein,CD34 and vimentin in the majority of cells,and negative for desmin and S100.A diagnosis of GIST,with high risk aggressive behavior was made.An abdomino-perineal resection was discussed,but refused.The follow-up included clinical evaluation and anal ultrasound.After 5 years the patient is well,with maintained continence and no evidence of local recurrence. | Nuno Carvalho Diogo Albergaria Rui Lebre Joo Giria Vitor Fernandes Helena Vidal Maria José Brito | 2014 | World Journal of Gastroenterology2014，20，1： | 1 |
