Abstract

 A Case of Subcutaneous Destructive Facial Swelling in a Dog Caused by Mucor Species

A three-year-old Black Jack dog was presented in August, 2014 to Mansoura veterinary teaching hospital, Egypt for investigation of a firm non-painful subcutaneous swelling beneath the right eye. Oral examination revealed normal lips, gums, teeth, tongue and palate. Incision of the swelling discharged whitish yellow fluid, pyogranulomatous masses and bloody exudates. Subsequent biopsy and culture examination revealed a pure growth of a Mucor species. On necropsy, right maxillary bone, underneath the swelling, showed erosion and destruction of bony wall extending into orbit, anterior ethmoidal sinus and soft tissue of right cheek. Histopathological evaluation showed pyogranulomatous inflammation associated with intra lesional hollow thin walled branched aseptated hyphae characteristic of Mucor species. The fungus was visualized by periodic acid Schiff (PAS) and Grocott’s methenamine silver (GMS) stain.
