Oncogenic Osteomalacia as the Initial Presentation of Pleural Epithelioid Hemangioendothelioma: A Case Report.

Epithelioid hemangioendothelioma (EHE) is a rare form of vascular neoplasm that can manifest with various symptoms or be discovered incidentally in asymptomatic patients. In this report, we describe a case of a 56-year-old male who presented with progressive lower limb weakness over four years. The evaluation revealed severe hypophosphatemia, an inappropriately normal fibroblast growth factor 23 C-terminal (cFGF-23) level, and a 30 x 20 mm hypermetabolic right pleural mass, which was subsequently proven to be EHE.

Adrenocorticotropic Hormone-Dependent Cushing's Syndrome Complicated With Gastric Ulcer Perforation in a 30-Year-Old Saudi Female: A Case Report and a Review of the Literature.

Gastrointestinal perforation is a well-addressed complication of exogenous hypercortisolism; however, patients with endogenous Cushing's syndrome (CS) do not usually experience this condition in clinical practice. The literature on this subject is limited and consists solely of clinical case reports/series with only 23 instances of gastrointestinal perforation occurring in individuals with endogenous Cushing's syndrome. This is mainly attributed to the rarity of Cushing's syndrome itself and the low chance of occurrence of such complications.
