A needle in the colon, the risk of ingested foreign objects: a case report.

Ingestion of foreign bodies is often found in clinical practice; however, intestinal perforation due to ingestion of foreign bodies is rare. Sharp and metallic objects are usually the ones that cause most complications. Preoperative diagnosis is difficult since the clinical presentation is vague and nonspecific presentation can simulate many abdominal pathologies.

Pneumoperitoneum and Pneumatosis cystoides intestinalis, a dangerous mixture. A case report.

Background: Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by gas infiltration into the intestine wall. When gas is seen in the intestinal wall, it is usually a sign of bowel wall infarction and a surgical emergency; therefore, an adequate differentiation of benign and urgent conditions of pneumatosis intestinalis is necessary to prevent misdiagnosis and inadequate therapies.

Case Presentation: We present the case of a 79-year-old male with past medical history of Alzheimer's, cholecystectomy, and umbilical hernia.

Giant ovarian cystadenocarcinoma in an adult patient, a rare finding in modern times.

Ovarian cancer (OC) is one of the most commonly diagnosed cancers among women. Regretfully due to its a broad spectrum of clinical behavior and challenging diagnosis most cases are diagnosed at a late stage. On rare occasions, these tumors can grow to massive sizes if left untreated, worsening the prognosis of the patient.

Subcapsular liver hematoma after extracorporeal shock wave lithotripsy, a rare complication.

Extracorporeal shock wave lithotripsy (ESLW) is a common and relatively safe procedure, with a high success rate and low adverse effects. Complications of this procedure are usually limited to the kidneys and almost always resolve spontaneously. However, on rare occasions, a frightening complication, as a hematoma of a parenchymatous organ, such as the liver can appear.

Gastric mixed adenoneuroendocrine carcinoma case report.

Mixed adenoneuroendocrine carcinomas are rare tumors that contain both an exocrine and an endocrine component. Since the latest classification by the World Health Organization and with the aid of immunostaining, more mixed adenoneuroendocrine carcinomas are now identified and diagnosed. Nonetheless, our knowledge of these tumors is still limited, notably concerning gastric variants, as the cases reported in the literature are very limited.

Massive retroperitoneal dedifferentiated liposarcoma in a young patient.

Liposarcomas are rare malignant tumors that mostly develop in the retroperitoneum. They have a broad behavioral spectrum, from small masses of tissue to highly aggressive tumors. The dedifferentiation process occurs in up to 10% and it's most likely to occur in the retroperitoneum, a process that not only changes its components but also its prognosis.

Laparoscopic approach to non-communicating intestinal duplication cyst in adult.

Intestinal duplication is rare congenital pathology generally diagnosed in infancy or early childhood. Presentation in adults is extremely rare. We present a case of a 36-year-old otherwise healthy female patient without any past medical history.
