Histopathological features of cutaneous and gastric habronemiasis in horse.
The aim of study was to describe clinico histopathological manifestations of cutaneous and gastric habronemiasis in horse. The adult worms live on the wall of the stomach and cutaneous of the host without internal migration. A 5 year old 700 kg warm-blood, cross gelding was referred to the Tehran School of Veterinary Medicine, Veterinary Teaching Hospital. The horse presented skin lesions around. In our survey, several raised granulomatous nodules with a cystic space and parasites within the cysts were observed. Also gastric rupture at greater curvature due to abscess and perforation through the serosa causing diffused peritonitis and subsequent death. Eosinophils and other inflammatory cells were present in large numbers. Furthermore, cutaneous lesions were characterized by single or multiple ulcerated timorous masses with eosinophil epithelioid cell infiltration and scattered necrotic debris. Granulation tissue and neutrophils were observed along the ulcerated area. In this report a case of cutaneous and gastric habronemiasis in a horse in Iran is described with special attention to confirmation of the clinical diagnosis.
