Anorectal melanoma: Report of two cases.

Introduction: Anorectal melanoma (AM) is a rare and aggressive type of cancer. Its symptoms often resemble those of common benign anal conditions, such as hemorrhoids, leading to frequent delays in diagnosis. Consequently, about one-third of patients have metastases at the time of their initial diagnosis.

Mesonephric carcinoma of the cervix associated with ovarian serous carcinoma: a case report.

Malignant mesonephric tumor of the uterine cervix is an extremely uncommon subtype of cervical adenocarcinoma with rare, documented cases in the literature. In this report, we present a case of 58 yo, with abdominal pain and ascites that was found to have a synchronous presence of a mesonephric adenocarcinoma of the cervix and advanced serous ovarian carcinoma on the surgical specimen. The histological study identified a tumor showing a mix of tubular and ductal growth patterns.

A case of intra-abdominal textiloma mimicking a mesenteric tumor.

Introduction: A textiloma or gossypiboma is a retained surgical material in the body after an operation. It may be asymptomatic or revealed by complications such as occlusion, perforation, and fistulization.

Case Report: We report a case of intraabdominal textiloma mimicking a mesenteric tumor.

Perforated ulcer at the gastrojejunal anastomosis: a rare complication of pancreaticoduodenectomy (case report).

Pancreaticoduodenectomy (PD) is recognized as one of the most intricate abdominal surgical procedures, often accompanied by high morbidity rates. The occurrence of an anastomotic ulcer at the gastrojejunal anastomosis post-pancreaticoduodenectomy surgery is a relatively uncommon complication, albeit potentially leading to severe, life-threatening consequences. The predominant symptomatology manifests as acute abdominal pain accompanied by peritonitis.

Pre-sternal Embryonic Dermoid Cyst: A Case Report.

Epidermoid and dermoid cysts are benign, usually slow-growing lesions classified as ectodermal inclusion cysts. These cysts form when epithelial remnants become trapped during the closure of the first and second branchial arch; however, a few cases are related to trauma or are iatrogenic. Diagnosis is made based on the cyst development history and imaging such as ultrasound.
