Tumores sincrónicos en un canino French poodle con hemangioma hepático y linfoma difuso de células B inmunoblástico esplénico.

Abstract

The following, a clinical case of a canine is describeb, male, unsterilized, french poodle, 9 years old and weighting 6.7 kg. Severe abdominal distension on clinical examination was evidenced and on abdominal palpation a firm consistency structure was perceived in the mesogastrium region with severe pain manifestation. The presumptive diagnosis was hepatic neoplasia, this was approximated by means of complementary diagnostic tests such as abdominal ultrasound and paraclinical examinations consisting of a hemoleukogram and biochemical profile (ALT, FA, PT, albumin, BUN and creatinine). The therapeutic approach consisted of an abdominal laparotomy with hepatic lobectomy of the left medial lobe, subsequently the mass was sent for histopathological study, reporting hepatic hemangioma. In-hospital treatment consisted of: cephradine, tramadol, dipyrone plus hyoscine, omeprazole and maropitant. Due to the progressive deterioration of the patient, his low response to treatment and the poor prognosis, the decision was made to euthanize with owners authorization and subsequently a necropsy and histopathology were performed. The post-mortem histopathological study reported diffuse splenic large cell lymphoma with apparent metastasis in the liver, this neoplasm is the one related to the deterioration of the patient and based on the lesions with various biochemical alterations presented. Additionally, for the correct classification of lymphoma, complementary immunohistochemistry (IHC) was performed to determine the clonality of B lymphocytes. In this case we describe a presentation of synchronous neoplasms in a canine, being this a condition of low report in this animal specie.
