Atypical transmissible venereal tumor in dogs

Background: The Transmissible Venereal Tumor (TVT), classified as a round cell tumor, is considered one of the oldestexisting tumors. It affects dogs all over the world and has a contagious characteristic. Despite the good response to clinicaltreatment in most cases, it can sometimes have non-classical presentations and even different behavior. Thus, the presentstudy aims to report 3 cases of atypical TVT treated at the Veterinary Medical Teaching Hospital of the State University ofMaringá (UEM) in Umuarama, Paraná, aiming to describe the epidemiology and clinical-pathological aspects, focusingon the diagnostic method used, the treatment of choice and the clinical follow-up of each case.Cases: Case records of 3 intact male mongrel dogs with atypical Transmissible Venereal Tumor (case 1: intranasal; case2: intra-abdominal and case 3: cutaneous with lymph node metastasis) were reviewed regarding history, clinical signs,duration of clinical signs, examination findings, results and findings of complementary exams (hematological, biochemical,radiographic, ultrasonographic and cytological), treatment, follow-up and final result. Case 1: had an ulcerated mass in thenasal plane causing significant airway obstruction and respiratory difficulty. Case 2: had a lesion in a typical location (penilemucosa in the glans area) but with a large intra-abdominal mass in the lumbar paravertebral region, causing compressionof important structures. Case 3: on the other hand, had cutaneous TVT with several ulcerated plaque lesions all over theskin, in addition to popliteal lymph node enlargement due to metastasis later confirmed by microscopy. All dogs reportedwere mixed breed, intact males with free access to the street. Despite...

Feline Hyperesthesia Syndrome - Case Report / Síndrome da Hiperestesia Felina Relato de Caso

Feline Hyperesthesia Syndrome (FHS) is a clinical condition, characterized by involuntary muscle contractions and changes in behavior. It is a rare syndrome, often of unknown origin, and the most common associated causes are skin related disorders, such as bacterial, fungal dermatitis, allergics and immune-mediated diseases. Causes related to the central nervous system and behavioral disorders are also reported. The clinical signs are varied, the diagnosis is often complex and the treatment varies according to the underlying cause. The purpose of this case report is to describe a case of FHS of possible dermatological etiology. A three-year-old Siamese male feline was treated for feline lower urinary tract disease throughout the duration of nine days. Associated, the animal also presented erythematous areas and hypotrichosis all over the face, especially around the eyes, nose and auricular pavilions, along with painful hypersensitivity to the touch and skin fasciculations in the lumbar and coccygeal region and pelvic limbs. An histopathological exam of the skin lesions was performed, where a chronic, superficial perivascular dermatitis was seen to be proliferative. Based on physical examination findings and additional tests, the animal was diagnosed with feline hyperesthesia syndrome secondary to dermatopathy.(AU)

A Síndrome da Hiperestesia Felina (FHS) é uma condição clínica, caracterizada por contrações musculares involuntárias e mudanças de comportamento. É uma síndrome rara, muitas vezes de origem desconhecida, sendo que as causas mais comuns associadas são doenças relacionadas à pele, tais como dermatites bacterianas, fúngicas, alérgicas e doenças imunomediadas. Causas relacionadas ao sistema nervoso central e distúrbios comportamentais também são relatadas. Os sinais clínicos são variados, o diagnóstico muitas vezes é complexo e o tratamento varia de acordo com a causa de base.  O objetivo deste relato de caso é descrever um caso de FHS de possível origem dermatológica. Um felino, macho, de três anos, da raça Siamês, foi atendido apresentando doença do trato urinário inferior felino há nove dias. Associado, o animal possuía áreas eritematosas e de hipotricose por toda a face, principalmente ao redor dos olhos, nariz e pavilhões auriculares, juntamente com hipersensibilidade dolorosa ao toque e fasciculações cutâneas na região lombar, coccígea e membros pélvicos. Foi realizado exame histopatológico das lesões de pele, onde foi visualizada dermatite superficial perivascular crônica proliferativa. Com base nos achados de exame físico e nos exames complementares, o animal foi diagnosticado com síndrome da hiperestesia felina secundária à dermatopatia.(AU)
