Two years earlier, the dog underwent a gastrotomy to retrieve a foreign object and recovered uneventfully. Fluid aspirated from the lesions was culture-negative for aerobic and anaerobic bacterial growth. Abdominal ultrasound demonstrated a large intra-abdominal mass with apparent communication with the cutaneous lesion, along with gossypiboma from the previous laparotomy. Neoplasia or a sterile abscess were suspected. Exploratory laparotomy was performed and revealed that the intra-abdominal mass was adhered to the abdominal midline and the greater curvature of the stomach. The masses and affected portions of the body wall and stomach were resected and histopathology was consistent with phaeohyphomycosis. Antifungal therapy with voriconazole (6.3 mg/kg, PO, q12h) was initiated. At 1 mo after surgery, all clinical signs had resolved. At 4 and 7 mo after surgery, the dog continued to thrive despite 2 small masses, seen on abdominal ultrasound imaging on the intra-abdominal midline, suggestive of reoccurrence. Continued voriconazole therapy was administered in lieu of further surgical excision. One year after surgery, the masses were no longer present on ultrasonographic evaluation. Phaeohyphomycosis is a rare, opportunistic fungal infection that typically affects the dermis and subcutis of immunocompromised dogs. This is the first report of phaeohyphomycosis in an immunocompetent dog and involving the dermis, subcutis, and abdominal viscera.

Equivalence of outcome is a concept that crosses animal, human, and environmental health standards. Loosely defined, it is taken to mean achieving a similar reduction in risk by different methods. Countries conduct assessments known as health infrastructure evaluations (HIE) to allow safe trade in commodities of food, plant, and animal origin. This review analyzes the use of HIE for trade purposes, with an added focus on their One Health context.
