Alpha-Fetoprotein-Producing Hepatoid Adenocarcinoma of the Stomach.

Hepatoid adenocarcinoma of the stomach (HAS) is a rare type of gastric cancer with unique clinicopathological features. HAS has a poor prognosis because of early liver, lung, and lymph node metastasis. Owing to its rarity and malignant potential, data on its pathophysiology and management are scarce.

A Plasmacytoma of the Lateral Pharyngeal Wall: A Diagnostic Enigma.

Plasmacytoma is a rare plasma cell dyscrasia that grows in bones or soft tissues such as the pharynx. Soft tissue plasmacytomas are rare, and a higher burden has been reported in the upper aero-digestive tract, often manifesting as hoarseness, dysphagia, or odynophagia. Due to their rarity, extramedullary plasmacytomas (EMPs) have unknown prognostic factors, and guidelines for optimal management are still lacking.

The Cancer Diaspora: A Rare Case of Pseudomyxoma Peritonei of Appendiceal Origin.

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.

Rectal Tropism: An Extremely Rare Case of Prostate Cancer Recurrence With Metastasis to the Rectum Postradical Prostatectomy.

Prostate cancer is the most common noncutaneous cancer affecting men in the United States. It is a slow-growing tumor that can be missed during the nascent phase. Prostate cancer commonly metastasizes to the bones and nearby lymph nodes.

Erdheim-Chester disease presenting at the central nervous system.

Erdheim-Chester disease is a rare non-Langerhans cell histiocytosis (LCH) that affects different body systems. It was recently recognized as a neoplastic disorder after identifying an activating mutation of the MAPK pathway. Neurological presentations of ECD are rare.

Annular Indentation of the Ventricles in a Stillborn: A Case Report and Literature Review.

Idiopathic indentation of the cardiac ventricles in a fetus has not been previously reported. Reported cases of congenital ventricle indentation are either caused by pericardial abnormalities or myocardial defects. : We describe an incidental finding of annular indentation of the lower part of both ventricles in a stillborn male.

Upper Gastrointestinal Crohn's Disease: Literature Review and Case Presentation.

Upper gastrointestinal tract predominant Crohn's Disease (CD) remains an elusive clinical entity, manifesting limited or vague symptomatology, eluding clinical suspicion, and delaying subsequent diagnostic evaluation. As a result, it has not been widely described and there is a lack of clear recommendations for diagnosis or management. Standard IBD evaluation including serologic testing, imaging, and endoscopy may initially not be fruitful.
