ABSTRACT
Mouth-related neoplastic and non-neoplastic lesions are commonly found in dogs and cats, and their diagnosis and classification are important for treatment planning and prognosis. This retrospective study analyzed mouth-related lesions in dogs and cats between 2000-2019 from the animal pathology laboratory of the Universidad de Antioquia, Medellín, Colombia. A total of 640 mouth-related lesions affecting 572 dogs (89.4%) and 68 cats (10.6%) were reviewed. Lesions were classified as neoplastic or non-neoplastic. The average age for neoplastic lesions was 8.6 years in dogs and 6.4 years in cats, while for non-neoplastic lesions the average age was 7.7 years for dogs and 5 years for cats. Data was analyzed using descriptive statistical methods according to year and source of report, demographic information for the animal, location of the lesion, and diagnosis. Tissue origin and behavior were variables considered for neoplastic lesions. Melanoma was the most common neoplasia in dogs and squamous cell carcinoma was most common in cats. The most frequent non-neoplastic lesion in dogs was gingival hyperplasia, while in cats the inflammatory lesions showed a wide range of morphological diagnoses. This study described many pathological lesions affecting the oral cavity for both dogs and cats and provides useful epidemiological data for both pathologists and clinicians.

Granuloma Piogénico (GP) es una lesión reactiva producida por un crecimiento excesivo del tejido conectivo, es frecuente en la mucosa bucal muy especialmente en el tejido gingival. Se trata de una patología de crecimiento rápido, sangrante y se asocia a la presencia de irritantes locales, microtraumatismos, entre otros factores. Tiene importante predilección por el género femenino entre la segunda y quinta década de la vida. Lesiones como malformaciones vasculares, lesión periférica de células gigantes y sarcoma de Kaposi son sus principales diagnósticos diferenciales y el tratamiento de elección es la escisión quirúrgica. A continuación se presenta un caso clínico poco común debido a las características clínicas de la lesión y la edad del paciente, pues se trata de un infante del género masculino de 5 años de edad, que acudió a la Facultad de Odontología de la UCV, referido por su odontólogo general, debido a la presencia de una lesión tumoral en el sector posterior derecho maxilar, adyacente a la cara distal del 55 de 2.5cm de tamaño. Se realizó la escisión quirúrgica de la lesión posterior a la evaluación de los exámenes preoperatorios y fue analizada histopatológicamente, donde se confirmó el diagnóstico inicial de GP
Pyogenic Granuloma (PG), is a reactive lesion caused by an excessive connective tissue growth and it frequently appears on oral mucosa, especially the gingiva. The PG present fast growth, bleeding propensity and it is associated, among other factors, to local irritation and minor trauma. It has predilection for female patients between second and fifth decade of life. The main differential diagnosis can be made with lesions such as: vascular malformations, peripheral giant-cell lesion and Kaposi's sarcoma. Surgical excision is the treatment of choice. This article presents a case report of an uncommon lesion regarding its rare clinical features and age of the patient. A 5 year old male patient who attended the Facultad de Odontología of Universidad Central de Venezuela, referred by his dental practitioner, presented a tumor-like lesion. The lesion was 2.5 cm in size and located on posterior right maxilla next to distal surface of 55. Surgical excision was performed after full laboratory test evaluation. The histopathology findings confirmed initial diagnose of PG
