Proventricular Hemangiosarcoma Identified in a Broiler at Slaughter

A discrete circumscribed red nodule present on the surface of the proventriculus of a 7-week-old broiler was diagnosed as a hemangiosarcoma. Histologically, discrete islands and dense sheets of anaplastic ovoid to spindle-shaped basophilic cells surrounded irregular vascular clefts and spaces. Mitot...

Description
Summary:A discrete circumscribed red nodule present on the surface of the proventriculus of a 7-week-old broiler was diagnosed as a hemangiosarcoma. Histologically, discrete islands and dense sheets of anaplastic ovoid to spindle-shaped basophilic cells surrounded irregular vascular clefts and spaces. Mitotic figures were focally numerous, and extension into the tunica muscularis of the proventriculus was seen. Neoplastic islands were also present in the tunica mucosa and the adjacent mesentery. /// Un nódulo rojo circunscrito presente en la superficie del proventrículo de un pollo de engorde de 7 semanas de edad se diagnosticó como un hemangiosarcoma. Histológicamente, el neoplasma estaba compuesto de islas discretas y capas densas de basófilos anaplásicos ovoidales o en forma de huso, formando fisuras y espacios. Dentro del neoplasma se observaron múltiples focos hemorrágicos cavernosos, numerosas figuras mitóticas e invasión de la túnica muscular del proventrículo. Las islas focales neoplásicas también fueron observadas en la túnica mucosa y en el mesenterio adyacente.
