Bone and pulmonary metastasis from a mammary adenosquamous carcinoma in a bitch / Metástase óssea e pulmonar de adenocarcinoma escamoso mamário em cadela

Mammary tumors are the most common in bitches, and bone and pulmonary metastases are not well described. Adenosquamous mammary carcinoma is a rare tumor that can be classified as a type of metaplastic tumor. This report describes the clinical and histopathological findings of this atypical presentation of mammary carcinoma in an 11-year-old, spayed, Poodle. Surgery was performed to remove malignant mammary nodules with a provisional diagnosis of carcinoma on cytologic examination. Thirteen months later, the dog returned showing left pelvic limb lameness that had persisted for 6 months prior to the consultation. The patient showed right pelvic limb lameness and a mass in the same limb. Radiographs of the affected limb revealed a pathological fracture in the femoral diaphysis and proliferation of the periosteum. After clinical staging, a left pelvic limb amputation was performed. A diagnosis of grade II adenosquamous mammary carcinoma was made through histopathology and immunohistochemistry. Although uncommon, bone and pulmonary metastases from mammary tumors, such as adenosquamous carcinoma, can be considered differential diagnoses for bony tumors. This report highlights the aggressive nature and significant metastatic potential of the adenosquamous carcinoma.

Os tumores mamários são os mais comuns em cadelas e as metástases ósseas e pulmonares não são bem descritas. O carcinoma mamário adenoescamoso é um tumor raro que pode ser classificado como um tipo de tumor metaplásico. Este relato descreve os achados clínicos e histopatológicos dessa apresentação atípica de carcinoma mamário em um Poodle de 11 anos de idade, castrado. A cirurgia foi realizada para remover nódulos mamários malignos com diagnóstico provisório de carcinoma no exame citológico. Treze meses depois, a cadela retornou apresentando claudicação do membro pélvico esquerdo que persistia por seis meses antes da consulta. O paciente apresentava claudicação do membro pélvico direito e uma massa no mesmo membro. A radiografia do membro afetado revelou fratura patológica na diáfise femoral, proliferação do periósteo e áreas de osteopenia. Após estadiamento clínico, foi realizada amputação do membro pélvico esquerdo. O diagnóstico de carcinoma adenoescamoso mamário grau II foi feito através da histopatologia e imunohistoquímica. Embora incomuns, as metástases ósseas e pulmonares de tumores mamários, como o carcinoma adenoescamoso, podem ser consideradas diagnósticos diferenciais para tumores ósseos. Este relatório destaca a natureza agressiva e significativo potencial metastático do carcinoma adenoescamoso.

Feline sarcoid: case report / Sarcóide Felino: relato de caso

It was aimed to describe the clinical and histopathological characteristics of a case of sarcoid tumor in an adult, mixed-breed female cat, with a history of a small increase of volume on the ear. At physical examination, no alteration was found with the exception of the presence of a rounded dermal nodule of 3.0 x 1.5 x 0.5 cm, ulcerated, well-circumscribed, pedunculated, pinkish, solid-elastic, mobile and painless, located on the skin of the border of the auricular pavilion. In the cytological examination of the nodule, the involvement of a benign mesenchymal neoplasia was found. Furthermore, alterations in the hematological examinations were not observed, nor in the imaging tests, and the serological analyses for infection by the leukemia and immunodeficiency were negative. The surgical excision of the nodule was performed, and then the nodule was submitted to histopathologic examination. Microscopically, was verified superficial and deep dermis distended by a non-encapsulated nodule, covered by intact skin, constituted by fibroblasts disposed in random beams predominantly spaced, at times, interspersed by collagen fibers; epidermis with focally extensive acanthosis, projecting papillae in the direction of the superficial dermis. Furthermore, was observed accentuated orthokeratotic hyperkeratosis and, in occasional vessels, the presence of a discreet lymphoplasmocitary

Objetivou-se descrever as características clínicas e histopatológicas de um caso de sarcoide em uma gata, adulta, sem raça definida, com histórico de pequeno aumento de volume na orelha. Ao exame físico, não constatou-se nenhuma alteração à exceção da presença de um nódulo dérmico arredondado de 3,0 x 1,5 x 0,5 cm, ulcerado, de circunferência circunscrita, pedunculado, rosado, firme-elástico, móvel e indolor, localizado na pele da borda do pavilhão auricular. Ao exame citológico do nódulo, constatou-se o envolvimento de uma neoplasia mesenquimal benigna. Ademais, não foram observadas alterações nos exames hematológicos, nem de imagem e as análises sorológicas para infecção pelo vírus da leucemia e imunodeficiência foram negativas. Procedeu-se com a excisão cirúrgica do nódulo, o qual foi submetido a exame histopatológico. Microscopicamente, verificou-se derme superficial e profunda distendida por nódulo não encapsulado, revestido por pele íntegra, constituído por fibroblastos dispostos em feixes aleatórios predominantemente espaçados e, por vezes, entremeados por fibras colágenas; epiderme com acantose focalmente extensa, projetando papilas em direção à derme superficial. Ademais, observou-se hiperqueratose ortoqueratótica acentuada e, em ocasionais vasos, presença de discreto infiltrado linfoplasmocitário e área focal de hemorragia, compatível com sarcoide felino. Decorridos 11 meses após a conchectomia, não constatou-se recidivas. Este relato alerta a necessidade de incluir esta neoplasia nos diagnósticos diferenciais de neoformações cutâneas em gatos com as características supracitadas.

Carcinoma de células escamosas multicêntrico com envolvimento de anexos oculares em um cão / Multicentric squamous cell carcinoma with the involvement of the ocular annexes in a dog

Background: The cutaneous squamous cell carcinoma (cSCC) is considered to be a frequent neoplasm in dogs, however,its origin in ocular annexes, especially in relation to the conjuctival location, is a rare finding in dogs. Therefore, it wasaimed to report the occurrence of a multicentric SCC, with the involvement of ocular annexes in a dog, emphasizing itsclinical characteristics and histopathological findings.Case: A 6-year-old non-castrated white-coated Pitbull dog was attended, with a history of increased volume and bloodysecretion in the left eye, with an evolution of approximately six months. By means of general physical examination, ulcerated lesions in the foreskin and scrotum were found. During the ophthalmologic examination was identified an extensiveand irregular exophytic mass, of a reddish color and with a cauliflower-like appearance, located in the inferior bulbarconjunctiva and third eyelid of the left eye, accompanied by a large quantity of piosanguinolenta secretion, mainly duringmanipulation. Other alterations were observed, such as, meibomitis, conjuctival hyperemia, hypopyon, corneal edema andloss of sight. In the right eye, the only alteration found was conjunctival hyperemia. The hemograma revealed discreetanemia; the serum biochemical profile was inside the normal range and there was no evidence of metastasis in the imaging examinations. The animal was submitted to the incisional biopsy of the lesions for histopathological analysis, whichrevealed a proliferation of neoplastic epithelial cells, highly pleomorphic, composed of eosinophilic cytoplasm, whichvaried from scarce to moderate, of indistinct borders, with a large nucleus and loose chromatin and large and evidentnucleolus, compatible with SCC, enabling, also, the classification as multicentric...

Presença de Leishmania sp. e Dirofilaria immitis em / Tumor Venéreo Transmissível Canino cutâneo / Presence of Leishmania sp. and Dirofilaria immitis in Cutaneous Canine Transmissible Venereal Tumor

Background: Canine Transmissible Venereal Tumor (CTVT) is a neoplasm transmitted by implantation of its cells into genitaland extragenital organs, while Heartworm and Visceral Leishmaniasis are zoonosis transmitted by hematophagous insectsthat are often underdiagnosed in asymptomatic animals. Coinfection by the agents of these parasitosis is well documented,however, the association of both diseases with the CTVT is still unusual. Thus, it was aimed to report a case of incidentalidentification of microfilariae of D. immitis and amastigotes forms of Leishmania sp. in cutaneous CTVT by cytology in anasymptomatic dog for the parasitosis.Case: A 6-year-old, male, mongrel, sexually intact dog from the city of Patos, Paraiba, Brazil, was presented with a cutaneouscircumscribed tumoral lesion in a region adjacent to the right olecranon, with an ulcerated surface of reddish color, havingareas of necrosis inside and larvae (myiasis), draining bloody secretion. The material was collected for cytological analysis,which proved to be Canine Transmissible Venereal Tumor (CTVT) with the presence of amastigote forms of Leishmania sp.and microfilariae of D. immitis among neoplastic cells. Blood count, serum urea, creatinine and albumin, ALT, AST, FA,CK, Na+, K+, Ca++, CK-MB, Troponin I (cTnI), Snap 4Dx Plus (Idexx®), Snap Leishmania (Idexx®), and Knott’s test wereperformed, plus chest radiography, blood pressure measurements and electrocardiogram (ECG).

Effects of autohemotherapy on hematologic parameters and morphology of canine oral papillomatosis

Background: Several treatments for oral papillomatosis in dogs, with satisfactory results, have already been described in the literature. However, there is need for further studies regarding remission time, association and exposure to drugs, side effects, cost-effectiveness and reproducibility of results. Autohemotherapy (AHT) is a therapeutic technique increasingly used in veterinary medicine that has been providing satisfactory clinical results to treat several pathologies. The procedure consists of removing blood by intravenous puncture that is immediately re-administered via intramuscular, subcutaneous, intravenous or intradermal. Although the empirical isolated use via intramuscular reached excellent results in routine medical treatment of dogs and since few studies and protocols have been described for this species, many times the treatment is based on the experience with the bovine papillomatosis. To this end, this report describes a case of canine oral papillomatosis treated with autohemotherapy (AHT), emphasizing the dosage and clinical evolution of the case. Case: A one-year-old mongrel dog rescued from the street eight months earlier was treated. The animal was thin resulting from the small food amount ingested due to feeding difficulty, infested with ticks, had bad breath and few small warts on the lips, which, after five months, grew and multiplied, and were distributed throughout the oral cavity. The animal clinical history led to papillomatosis diagnosis, which was confirmed by cytological and histopathological exams. The AHT treatment consisted of taking 5 mL of whole blood without EDTA and immediately injecting this volume intramuscularly, every four days until the total remission of the clinical symptoms. Every four days, the papilloma fall off, and involution processes were recorded through a detailed macroscopic analysis of the warts […](AU)

Alterações radiográficas de 131 cães com cardiopatia congestiva / Radiographic alterations of 131 dogs with congestive heart disease

The objective of this study was to describe the radiographic alterations of 131 cardiopatic dogs treated at the Small Animals Medical Clinic, Veterinary Hospital of the Federal University of Campina Grande. From January 2007 to December 2012, all clinical records of dogs attended in the routine were selected, by means of selecting animals that had a history, and clinical signs compatible with heart disease. From these, the radiographic examinations were evaluated, describing the alterations found. Cough, fatigue and apathy were the most frequent clinical complaints. Each animal had more than one radiographic alteration, with pulmonary edema (48,1%), HSV greater than 10.5 (42,5%), tracheal dorsal displacement (34,3%), greater contact with the external bone (34,3%) and rounded silhouette (32,8%) the most frequent findings. An extensive knowledge of the radiographic changes related to the cardiological patient should be recognized, in order to aid in the rapid identification of the patients with heart disease.

Aspectos clínicos do tumor venéreo transmissível canino (Tvtc) linfóide, plasmocitóide e misto / Clinical aspects of lymphoid, plasmocytoid and mixed canine transmissible venereal tumor (TVTc)

The objective of this study was to describe the clinical aspects of the subtypes of Canine Transmissible Venereal Tumor (TVTc). The clinical record of 40 dogs with the cytologic diagnosis of TVTc was evaluated. Of these was selected information about classfication, clinical complaint and affected organs with their specific locations. In this study, the plasmocytoid TVTc prevailed. The predominant clinical complaint was penile bleeding (14/40) and vaginal bleeding (13/40). As to the location, genital (G) (34/40) and extragenital (EG) (17/40) tumors were observed, with TVTcL (G-66,66% and EG-66,66%), TVTcM (G-90% and EG-30%) and TVTcP (G-90,47% and EG-38,08%). Among the genitals, the base, body and gland prevailed, and in the vagina: ventral and dorsal floors. In the extragenital tumors, there were changes in the skin, mouth, subcutaneous, nasal region and eye. It was concluded that the TVTcP prevailed more in the skin, while the TVTcL in the head region.

Tumor venéreo trasmissível canino em mucosa vaginal com metástase em pele e globo ocular / Transmissible venereal tumor canine in vaginal mucosa with metastasis on the skin and eye ball

A six year old bitch had ulcerated, friable, easily bleeding masses similar to cauli flower in submucosa in the dorsum-posterior region of the vagina at the junction with the vestibule.

Cryptococcal sialoadenitis in a dog

Background: Salivary gland diseases in dogs have an overall incidence of 0.3%. Sialocele and sialoadenitis are the most common injuries and are usually caused by infectious diseases, especially of bacterial origin. Currently, Cryptococcus neoformans has not been registered as the etiological agent since fungal participation is unusual. This case report describes a cryptococcal sialoadenitis in a dog. Case: A 1.9-year-old male poodle had a swelling of the right submandibular region, combined with dry cough and snoring that persisted for about 30 days. The dog often walked in the town square, which has pigeons, and was seen eating chicken droppings. The dog was diagnosed with sialoadenitis in the right submandibular salivary gland. The following laboratory tests were performed cytology, fungal culture, blood count, search for hemoparasites, total plasma protein (ppt), alanine aminotransferase dosage (ALT), alkaline phosphatase (ALP), urea (U), creatinine (CREA), Albumin (ALB), total protein (TP), globulin (GLOB) and amylase (AML). In addition, the dog underwent cervical, thoracic and abdominal ultrasound, and cervical x-rays. The cytology results showed fungal sialoadenitis caused by Cryptococcus neoformans. The blood test results evidenced thrombocytopenia and increased ppt, TP, GLOB, and AML. The lungs and heart x-rays results showed no alterations. However, the proximal third [...]

Cryptococcal sialoadenitis in a dog

Background: Salivary gland diseases in dogs have an overall incidence of 0.3%. Sialocele and sialoadenitis are the most common injuries and are usually caused by infectious diseases, especially of bacterial origin. Currently, Cryptococcus neoformans has not been registered as the etiological agent since fungal participation is unusual. This case report describes a cryptococcal sialoadenitis in a dog. Case: A 1.9-year-old male poodle had a swelling of the right submandibular region, combined with dry cough and snoring that persisted for about 30 days. The dog often walked in the town square, which has pigeons, and was seen eating chicken droppings. The dog was diagnosed with sialoadenitis in the right submandibular salivary gland. The following laboratory tests were performed cytology, fungal culture, blood count, search for hemoparasites, total plasma protein (ppt), alanine aminotransferase dosage (ALT), alkaline phosphatase (ALP), urea (U), creatinine (CREA), Albumin (ALB), total protein (TP), globulin (GLOB) and amylase (AML). In addition, the dog underwent cervical, thoracic and abdominal ultrasound, and cervical x-rays. The cytology results showed fungal sialoadenitis caused by Cryptococcus neoformans. The blood test results evidenced thrombocytopenia and increased ppt, TP, GLOB, and AML. The lungs and heart x-rays results showed no alterations. However, the proximal third [...](AU)

Capillaria plica em felino assintomático: um achado ultrassonográfico / Capillaria plica in an asymptomatic feline: an ultrasonographic finding

The aim of this report was to describe a case of urinary capilariosis in a feline and an ultrasonographic finding of Capillaria plica in the urinary bladder. A female feline, 14-years-old, was seen presenting a history of weight loss and anorexia for five days. A hemogram, renal and hepatic serum biochemistry, total protein dosages and albumin and urinalysis were performed. The urinalysis showed dark yellow urine, elevated density, turbid aspect, proteinuria, hematuria, cylindruria, presence of leucocytes and bacteria. The microscopic examination of the urinary sediment revealed the presence of oval and colourless eggs with a thick capsule and bioperculated, characterized as being of C. plica. Treatment with levamisole was carried out, however some of the parasites eggs were still verified after the therapy. An abdominal ultrasonography was performed being visualized, in the urinary bladder, a filiform mobile hyperechoic structure of 0.59 cm of length and 0.28 of thickness, besides a thickening of the organs wall. Ivermectine was administered at a dose of 0.2 mg/kg, IM. After this treatment, C. plica eggs were no longer found in the urinary sediment. The ultrasonographic examination of the urinary bladder may be a good tool for the confirmation of the diagnosis in these cases.

O objetivo desse relato foi descrever um caso de capilariose urinária em um felino e um achado ultrassonográfico de Capillaria plica na vesícula urinária. Um felino, fêmea, de 14 anos de idade, foi atendido apresentando um histórico de perda de peso e anorexia por cinco dias. Foram realizados hemograma, bioquímica sérica renal e hepática, dosagens de proteína total e albumina e urinálise. A urinálise mostrou uma urina amarelo-escura, elevada densidade, aspecto túrbido, proteinúria, hematúria, cilindrúria, presença de leucócitos e bactérias. O exame microscópico do sedimento urinário revelou a presença de ovos incolores, bioperculados e ovais com uma cápsula espessa, caracterizados como sendo de C. plica. Foi realizado tratamento com levamisol. No entanto, alguns ovos do parasita ainda foram verificados após o tratamento. Uma ultrassonografia abdominal foi realizada sendo visualizada, na vesícula urinária, uma estrutura hiperecóica, móvel, de 0,59 cm de comprimento e 0,28 cm de espessura, além de uma parede do órgão espessa. Ivermectina foi administrada na dose de 0,2 mg/kg, IM. Após este tratamento, ovos de C. plica não foram mais encontrados no sedimento urinário. O exame ultrassonográfico da vesicular urinária pode ser uma boa ferramenta para confirmação do diagnóstico nesses casos.
