Most cholecystocolic fistulae are late complications of gallstone disease, but can also develop following carcinoma of the gallbladder when the necrotic tumor penetrates into the adjacent colon. Although no currently available imaging technique has shown great accuracy in recognizing cholecystocolic fistula, abdominopelvic computed tomography may show fistulous communication and anatomical details.Herein we report an unusual case of cholecystocolic fistula caused by gallbladder carcinoma, which was preoperatively misdiagnosed as hepatic flexure colon carcinoma.展开更多

The differential diagnosis is very difficult and some cases may result in an unnecessary esophagectomy. We reported herein a 48-year-old man with symptoms of dysphagia and pectoralgia for one month. Our primary diagnosis was established as esophageal carcinoma and the patient underwent surgical therapy. Histopathological examination of the excised tumor lesion and lymph nodes showed epithelioid granulomas, Langhans＇ giant cells, caseous necrosis. No evidence of malignancy has been found. The Mantoux test revealed a positive reaction with 20 mm in diameter. Antituberculous treatment was given alter operation. Clinicians should aware the features of ET and this rare disease should be considered in the differential diagnosis of esophageal lesions.展开更多

Due to the relatively infrequent presentation, it can be easily missed. Toe tourniquet syndrome is strangulation of the toes by what is usually hair, although synthetic fibres have also been described. It is considered a surgical emergency as left untreated, the tissues of the toe can become necrotic and the patient would lose that appendage. In this paper, we have done a literature review and written the article with illustrations which would explain this repeatedly misdiagnosed condition very thoroughly to all the clinicians dealing with this rare problem.展开更多
