We describe a rare case of Pneumocystis jirovecii pneumonia (PCP) in a heterosexual man with a pertinent medical history of well-controlled human immunodeficiency virus (HIV) on highly active antiretroviral therapy (HAART) and PCP prophylaxis with atovaquone. The patient presented with recurrent shortness of breath, worsening malaise, and fever, following treatment for hypersensitivity pneumonitis one month prior, including a twenty-four-day course of 40 milligrams daily glucocorticoid with taper. However, transbronchial biopsies, lavage, and cytology from prior admission were inconclusive. The patient refused video-assisted thoracic surgery (VATS) at that time. Upon readmission, bronchoscopy with right VATS and lung biopsy were performed. Grocott’s methenamine silver stain of right lung biopsy was positive for Pneumocystis jirovecii. This case is a rare example of PCP in a patient with a normal CD4 count (>487 cells/μL) and a low viral load (<20 copies/mL) despite PCP prophylactic antibiotics in the setting of recent iatrogenic immunosuppression.

Cutaneous pythiosis is described in four horses in Northern Paraná, Brazil. All animals presented ulcerative, granulomatous, cutaneous lesions that did not invade adjacent muscular tissues. Histopathological evaluations revealed eosinophilic granulomatous reactions associated with intralesional hyphae suggestive of Pythium insidiosum observed at the margins of coagula. P. insidiosum hyphae were visualized by Gomori’s methenamine silver stain.
