Venous intestinal ischemia of fungal origin as a cause of intestinal obstruction in immunocompromised patients: case report and literature review.

Background: Mucormycosis is a highly lethal opportunistic fungal disease caused by ubiquitous molds of the order Mucorales, with Rhizopus, Lichtheimia and Mucor being the most common genera. This rare disease primarily affects immunocompromised patients, with presentations ranging from rhino-orbito-cerebral infections to disseminated mucormycosis with angioinvasion, leading to thrombosis and tissue infarction. Gastrointestinal mucormycosis is the least common clinical presentation and is believed to be secondary to spore ingestion.

Erythema nodosum with incidental calciphylaxis secondary to zoledronic acid and denosumab.

Erythema nodosum (EN) is the most common clinical presentation of panniculitis, an inflammatory process that affects subcutaneous cellular tissue, characterized by the acute appearance of painful erythematous nodules predominantly in the lower extremities. An unusual case of EN is presented below, secondary to the administration of zoledronic acid (ZA) and denosumab, in which incidental histopathological findings of calciphylaxis were also found.
