Abstract Mucinous cystadenoma is a rare tumor of appendix it accounts for only 0.4% of the gastrointestinal tract malignancies and is reported rarely in literature. Therefore the surgical management is not yet established. Here we report a case of a 65 year old female who presented with a dragging sensation and a feeling of mass in right iliac fossa. Her computed tomography (CT) suggested an abscess formation of the parietal peritoneum. She was planned for laparotomy and upon exploration a mass was found arising from tip of retroperitoneal appendix. Whole of the appendix was studded with mucoid material. Limited right hemicolectomy was performed and histopathology of appendix showed mucinous cystadenoma with no evidence of malignant changes. Patient remained uneventful and was discharged on 4th post operative day. The unusual presentation of retroperitoneal pseudomyxoma without any intraperitoneal pathology, prompted us to report this case. Continuous...

Rare Entity

Primary mucinous cystadenocarcinoma (MCA) of breast is an exceedingly rare tumor with histologic resemblance to MCA arising in ovary, pancreas, and gastrointestinal tract. In this article, we present 2 additional cases of MCA of breast, one highlighting the diagnostic challenges of a rare entity that may potentially lead to unnecessary chemotherapy and the second case presenting with recurrence after 8 years of primary surgical excision defying the indolent behavior reported in the literature. To our knowledge, this is the first reported instance of such behavior.

Duodenal Carcinoma

AbstractDuodenal carcinoma is a rare tumor of the gastrointestinal tract of an insidious and secretive course, often diagnosed during the advanced stage of the disease. The study presented a case of a female patient diagnosed with duodenal carcinoma, subjected to two-staged surgery. The initial surgical intervention consisted in the implementation of a gastrointestinal anastomosis, followed by radical surgery by means of Whipple's method performed after three years.

AbstractAn inflammatory myofibroblastic tumor is a rare tumor of mesenchymal background commonly found in the pulmonary system. It is rarely found as a primary tumor in the gastrointestinal tract. We report an unusual presentation of this rare lesion causing intussusception and intestinal obstruction in a 39-year-old male.

Malignant perivascular epithelioid cell tumor (PEComa) is a rare tumor composed of hybrid tumor cells characterized by immunoreactivity for both melanocytic and smooth muscle markers. This paper describes the uncommon esophageal location of an 8 cm PEComa in a 75-year-old Caucasian man who was presented with ingravescent dysphagia. Although PEComas arising within the gastrointestinal tract are exceptional findings, clinicians should not exclude this class of tumors in the diagnostic investigation of a bulky lesion of the esophageal wall.
