Erythrodermic psoriasis is a rare subtype of psoriasis vulgaris that presents with diffuse erythema and desquamation over greater than 75% of the body's surface area. We present a case of a 57-year-old male who was admitted with a diffuse, erythematous scaly rash covering his entire body, with associated subjective fevers. Skin biopsy revealed erythrodermic psoriasis, and blood cultures were positive for methicillin-sensitive Staphylococcus aureus. Echocardiogram revealed a mitral valve vegetation. Clinical improvement was achieved with intravenous antibiotic administration and topical corticosteroids without the use of immunomodulators.

Coccidioidomycosis is an infection caused by inhalation of arthroconidia produced by dimorphic fungi in the genus Coccidioides. Forty percent of patients will develop an influenza-like illness with symptoms suggestive of a mild and self-limited respiratory infection; however, 5% of these individuals will develop extrapulmonary disseminated disease. An immunocompromised patient presented with right upper quadrant pain, ultrasound with pericholecystic fluid, in which a percutaneous cholecystostomy contained biliary fluid that grew the fungus Coccidioides immitis. Patient was initiated on intravenous amphotericin therapy and was followed closely with postoperative bile drainage with eventual laparoscopic cholecystectomy. We present a very rare case of disseminated coccidioidomycosis to the gallbladder.
