Plain-English summary
A study looked at 100 dogs diagnosed with lymphoma, a type of cancer that affects the lymph nodes. Symptoms varied, but in 29% of the dogs, swollen lymph nodes were the only sign noticed. The dogs ranged in age from 1.5 to 15 years, and most were of different breeds, with a suggestion that Boxers might be more likely to develop a specific type of lymphoma. The researchers used fine needle aspiration biopsies to confirm the diagnosis, finding that most cases were high-grade lymphomas, which are more aggressive. Treatment options were not detailed, but early diagnosis is crucial for better outcomes.

Abstract
Malignant lymphoma is one of the most common malignant tumours occurring in dogs. Fine needle aspiration biopsy (FNAB) is an excellent, specific diagnostic procedure used to assess pathological processes in lymph nodes. The aim of the present study was to conduct a cytopathological analysis of lymphoma in dogs and to analyse some epidemic aspects of occurrence of lymphoma in 100 dogs using Giemsa stained slides. Samples were obtained by fine needle aspiration biopsy, fine needle non-aspiration biopsy, lymph node impression smears and by examination of body cavity effusions. The determination of the type and subtype of tumour was made on the basis of the updated Kiel classification adopted for dogs. Based on cytopathological analysis, the lymphoma was diagnosed in 100 dogs: 44 were female and 56 male. The animals' age ranged from 1.5 year to 15 years (median: 7.5 years), the animals were of different breeds (72% of all dogs belonged to 28 different breeds) and crossbreeds (28%). In 29% of dogs the regional or general lymphadenomegaly was the only clinical sign observed, in remaining cases (71%) at least one abnormality connected to lymphoma was found. Among all diagnosed lymphomas, high-grade lymphomas were more prevalent (86% of all cases) than low-grade lymphomas (14% of all cases). The possibility of boxers having a predisposition to T cell lymphoma development could be also suspected.
