Pathology of Ceruminous Gland Adenoma in a Doberman Dog

Abstract

Ceruminous gland adenoma of a 10-year-old male neutered Doberman dog is described in this study. Small nodular growth was noticed on clinical examination which was partially obstructing the lumen of the external ear canal. The tumorous mass was surgically excised and processed for histopathological examination. Microscopically, the tumorous mass revealed cystic alterations and glandular epithelial growth with a polypoid pattern. The glandular cuboidal cells lining the cyst were either pile up or attenuated and supported by a stroma. The glandular tubule lumen was filled with pale eosinophilic material along with a, degenerated neutrophils, necrotic debris, few sloughed-off epithelial cells and brown pigment laden macrophages.
