High-Grade Lymphoblastic Lymphoma Mimicking Burkitt - Like Lymphoma in a Puppy: Case Report

Abstract

Burkitt-like lymphoma (B-LL) is a rare and aggressive high-grade B-cell malignancy in dogs. Present report describes a case of high-grade lymphoblastic lymphoma in a 2-month-old, non-descriptive male puppy with clinical signs of progressive abdominal distension, emaciation and vomiting. Radiographic, haematological, cytological, histopathological and immunohistochemical evaluations were performed. The neoplastic cells were negative for CD10 and CD20, ruling out classical B-LL. Based on histopathological and immunohistochemical findings, the case was diagnosed as high-grade lymphoblastic lymphoma, likely of T-cell origin. Present case emphasizes the importance of immunephenotyping in diagnosing canine lymphomas and highlights the occurrence of aggressive lymphoid neoplasms in young dogs.
