Here we describe an infrequent case of gastrointestinal stromal tumor of the rectum in a 57 year-old man with spindle cell neoplasm probably gastrointestinal stromal tumor and CT scan showed tumor from the anterior rectal wall and offered abdominoperineal resection for the same. The patient was started on imatinib and had a significant reduction in symptoms. The patient was reassessed with the CT scan, which showed a reduction in tumor size and Transanal minimally invasive surgery was planned for the patient. Use of imatinib prior to surgical resection to attain the reduced size of the tumor within the limit of resection is an attractive approach. Since tumor development can happen rapidly again after substantial tumor shrinkage, the best time to operate depending on resectability and the maximum therapeutic outcome remains divisive.
Diabetic foot ulcers are on the rise and increasingly associated with amputations. Fungal infections have recently been implicated in the nonhealing nature of these wounds. One hundred five patients treated as in-patients with nonhealing diabetic ulcers in a tertiary care hospital were included in this prospective study. Wound swabs and deep tissue biopsies were taken from these ulcers for fungal stain and culture and bacterial culture. Once the fungal stain or the culture study is positive, oral Fluconazole was started. Nineteen patients grew fungus in the ulcer, commonest species being Candida tropicalis (10.5%). The most common bacterial organism isolated with fungal infection is Pseudomonas followed by Enterococcus. Patients on prolonged antibiotic therapy showed statistically significant increase in fungal infection. Patients who underwent amputation within 15 days of admission were higher in fungal culture positive group, due to progression of ulcer in spite of antibiotic therapy. There is a definite correlation between incidence of amputation and fungal infection in whom antifungal therapy was not started, though not statistically significant. Fourteen patients, who did not undergo amputation, had faster wound healing and lesser progression of disease, with none of them requiring amputation after initiating antifungal therapy. Our study reveals that there is a definite relation between fungal infections and nonhealing nature of diabetic ulcers. Further randomized trials are necessary to substantiate this finding.

Background This study defines the disease profile in south Indian population and determine the clinic-pathological aspects of Gastro-Intestinal Stromal Tumors. Method In this prospective study patients diagnosed of gastrointestinal stromal tumors were taken thorough clinical examination and a database of Anthropometric details and clinical details were analyzed. Pathological data included tumor size, presence or absence necrosis, mitotic counts, immunohistochemistry for CD-117, CD-34. Results There were 44 patients with confirmed diagnosis of gastro-intestinal stromal tumor. The highest incidence was found in the 6 th decade. The most common symptoms were abdominal pain and gastrointestinal bleed. Stomach was most frequent site for gastro-intestinal stromal tumors. Immunochemistry for CD-117 was positive in 93.18% cases. Majority of tumors (79.5%) had pure spindle cell morphology and mitotic activity showed that 34% of the GISTs were of the high risk group. Forty two patients were suggestive of surgery as the primary treatment after presentation. Conclusion Abdominal pain was the most common presenting complaint. Majority of the tumors aroused from the stomach. The majority of the tumors had pure spindle cell morphology and 93% of the tumors were CD-117 positive. A significant relationship between tumor size, tumor necrosis and mitotic activity with large tumors having necrosis and high mitotic rate having high risk of malignancy, was observed. Surgical resection is considered mainstay of treatment of gastro-intestinal stromal tumor. Imatinib therapy should be given to patients in moderate to severe risk categories.
Introduction: To summarize the characteristics of cystic pancreatic adenocarcinoma, and to improve the general understanding of the imaging and pathologic features, and other pancreatic cystic diseases are compared for differential diagnosis. Method: This study included patients treated in our hospital from Jan, 2000 to Dec, 2014 due to pancreatic neoplasm. The imaging data and diagnostic imaging reports showed that in the cases that were diagnosed as pancreatic carcinoma there were cystic performance and "cystic mass". Result: Among the 485 cases of pancreatic carcinoma, 37 patients had cystic characteristics, accounting for 7.6%. 37 cases were all underwent surgical exploration. Based on preoperative imaging and gross pathological results, the cystic lesions were divided into the following four types : cyst with thin wall type (8cases); cyst with thick wall type (9cases); cystic-solid type (15 cases), and duct dilated type (5 cases). Pathological examination revealed that 29 cases were pancreatic ductal adenocarcinoma, which was moderately or poorly differentiated; and the other 8 cases were rare types of pancreatic carcinoma. Conclusion: Pancreatic ductal adenocarcinoma and its variants may have cystic features. When analyzing preoperative imaging findings of pancreatic cystic mass, the characteristics of the cystic pancreatic ductal adenocarcinoma should be fully taken into account to make differential diagnosis.
