Esthesioneuroblastoma or olfactory neuroblastoma is a malignant tumor and is derived from the olfactory neuroepithelium, rare in domestic species and particularly in equines. The present report corresponds to a 13-year-old equine patient who presented chronic respiratory disease with two years of evolution and in which period developed unilateral proptosis. At necropsy, an intracranial mass of soft consistency was found, partially delimited in the aboral region within the left nasal cavity, which extended, partially compromising the bones, presphenoids, ethmoids and membranous structures in the ethmoidal and orbital region, causing the partial protrusion of the eyeball and face compression of the left cerebral hemisphere, secondary lesions in the maxillary tuberosity, pterygopalatine fossa and guttural pouch. The microscopic findings corresponded to a neoplastic process of neuroendocrine...

The aim of this report was to describe six cases of canine splenic blastomycosis between 2013 and 2017 in two pathology laboratories in Bogotá, Colombia (Anatomopathology Laboratory of the University of La Salle-Bogotá, pathology laboratory of CORPAVET©). The samples were obtained by splenectomy consistent with the suspicion of neoplastic disease. The pathological diagnoses were considered as accidental findings of fungal splenitis caused by Blastomyces spores, as there was no clinical or laboratory evidence of joint systemic disease.

El objetivo de este artículo fue reportar y describir seis casos de blastomicosis esplénica canina entre 2013 y 2017 en dos laboratorios de patología en Bogotá, Colombia (Laboratorio de Anatomopatología de la Universidad de La Salle-Bogotá, laboratorio de patología de la empresa CORPAVET©). Las muestras fueron obtenidas por esplenectomía consecuente a sospecha de enfermedad neoplásica. Los diagnósticos patológicos fueron considerados como hallazgos accidentales de esplenitis micótica causada por esporas de Blastomyces, pues no hubo evidencia clínica o laboratorial de enfermedad sistémica conjunta.
