RESUMO
Pseudomyxoma peritonei (PMP) is a rare clinical entity characterized by widespread mucinous implants in the peritoneal cavity. Commonly seen in females in their 50s, PMP typically originates from ruptured appendiceal mucoceles that find refuge in the peritoneal space. Rarely, PMP may originate from the ovary, stomach, colon, or pancreas. Pseudomyxoma peritonei of colorectal origin is more malignant and has a lower survival rate. We report a case of a 59-year-old Hispanic woman with PMP who presented to the emergency room with a 3-month history of progressive abdominal distention. Pseudomyxoma peritonei was confirmed by computed tomography (CT) scan of the abdomen and pelvis and histopathology, and the patient underwent partial cytoreductive surgery. Given her Eastern Cooperative Oncology Group (ECOG) performance status of 1 despite extensive carcinomatosis, our patient may benefit from hyperthermic intraperitoneal chemotherapy (HIPEC) in the future.

Acute gastric volvulus is a surgical emergency that requires urgent intervention to prevent gastric ischemia and necrosis. Gastric volvulus manifests as an abnormal rotation or torsion of the stomach and may be associated with gastric outlet obstruction. This pathology can be classified as either mesentero-axial or organo-axial volvulus, depending on the axis of rotation. Similarly, it can be categorized as primary or secondary, depending on the etiology. We describe a case of a 63-year-old female with a history of peptic ulcer disease who presented with severe epigastric pain and vomiting of one-day duration. She was diagnosed with an acute mesentero-axial gastric volvulus, which was successfully reduced using a nasogastric tube.
