Characterization of epididymal and testicular histologic lesions and use of immunohistochemistry and PCR on formalin-fixed tissues to detect Brucella canis in male dogs

Camargo-Castañeda, Andrea M.; Stranahan, Lauren W.; Edwards, John F.; Garcia-Gonzalez, Daniel G.; Roa, Leonardo; Avila-Granados, Lisa M.; Hensel, Martha E. (2021)

In male dogs, Brucella canis frequently causes epididymitis, ultimately resulting in testicular atrophy and infertility. Although B. canis predominantly affects the epididymis, the misleading term “orchitis” is still ...

Collazos Osorio, Ruth | 2016

Se describe el desarrollo de un caso clínico de un canino macho de raza mestizo, de aproximadamente nueve años de edad con un peso de 9 kg. Al examen físico se observa un animal apoplético, en buena condición corporal,con algunas zonas alopécicas focalizadas en la región torácica, bilateralmente, con claudicación del miembro anterior derecho (MAD), en donde se halló unión de sus falanges y lo más relevante fue la presencia de una masa perianal en forma de coliflor; seguidamente se realizan exámenes complementarios como hemograma, que reportó, anemia normocítica hipocrómica regenerativa, trombocitopenia, leucopenia con linfopenia y proceso inflamatorio no controlado; en el examen de química sanguínea, se encontró la ALT dentro de los parámetros normales y la creatinina ligeramente disminuida. Partiendo de esta base, se instauró un tratamiento para los problemas dérmicos, donde después de una semana se practicó la eutanasia con el consentimiento del propietario, cuando se realizó la necropsia se extirpo la masa tumoral para envío a examen de histopatología cuyo resultado fue carcinoma de hepatoides e inmunohistoquímica para exactitud del tumor, donde el resultado sugirió melanoma amelánico altamente agresivo.

Characterization of epididymal and testicular histologic lesions and use of immunohistochemistry and PCR on formalin-fixed tissues to detect Brucella canis in male dogs

Camargo-Castañeda, Andrea M. | 2021

In male dogs, Brucella canis frequently causes epididymitis, ultimately resulting in testicular atrophy and infertility. Although B. canis predominantly affects the epididymis, the misleading term “orchitis” is still commonly used by clinicians. Of additional concern, diagnosis in dogs remains challenging because of variable sensitivity and specificity of serologic assays and fluctuations in bacteremia levels in infected dogs, reducing the sensitivity of blood culture. We describe here the histologic lesions in the scrotal contents of 8 dogs suspected of being infected with B. canis and clinically diagnosed with orchitis. We explored the possibility of using immunohistochemistry (IHC) and real-time PCR (rtPCR) in formalin-fixed, paraffin-embedded (FFPE) tissues to detect the presence of B. canis. Epididymitis of variable chronicity was identified in all 8 dogs, with only 3 also exhibiting orchitis. Using rtPCR, the presence of B. canis was identified in 4 of 8 dogs, with 3 of these 4 dogs also positive by IHC. These results suggest that rtPCR and IHC are promising techniques that can be used in FFPE tissues to detect B. canis when other detection techniques are unavailable. Additionally, accurate recognition of epididymitis rather than orchitis in suspect cases could aid in accurate diagnosis

The present work describes the case of a female canine of 11 years old, Schnauzer breed, that was attacked at the Veterinary Clinic of the University of Applied and Environmental Sciences. Anamnesis: Masses in the cervical region that were detected 1 week ago, decreased appetite and water consumption, depressed attitude and reduced physical activity in recent days. Clinical and laboratory findings: generalized lymphadenomegaly, dyspnea, tachypnea, pleural friction rub, lordosis, neutrophilic leukocytosis, presence of lymphoblasts and metamyelocytes, chemical analysis with hypercalcemia and azotemia; lymphocytic leukocytes and atypical mitosis were evidenced in the cytology, and in the immunohistochemistry, there was positive reactivity to the marker CD3+. Therapeutic approach: Treatment with COP chemotherapeutic protocol (cyclophosphamide, prednisone and vincristine). Conclusions: It was corroborated that T-cell lymphomas are more aggressive in their clinical presentation due to the rapid deterioration presented by the patient

This study was made with the purpose of informing veterinarians and students of veterinary medicine on the most recent updates of canine lymphoma, this research includes related topics to epidemiology, etiology, risk factors; another topics that the readers could find in this investigation are related too anatomical, morphological, histopathological and immunohistochemical classification; the author investigated the different methods that are available at veterinary medicine to make a diagnosis of this disease such as physical examination, hematology, imaging techniques, laboratory tests and molecular diagnosis; in addition to this, the most used therapeutic plans for patients are shown in this investigation, the most current treatments like the immunotherapy in veterinary medicine; this compilation has the purpose of showing the importance of new diagnostic aids in our country and in this way to make known a more accurate prognosis and then choose the most appropriate therapeutic plan for each patient offering a better quality of life to individuals suffering of CANINE LYMPHOMA.
