“…28,33,35,36 OVH resulted in a total FMFH remission rate of 94%, which is similar to previous studies that adopted the early administration of antiprogestin. 2,31,37,38 However, considering the complications of FMFH, and the fact that all cats that died were given injectable progestin and presented persistent mammary growth after OVH, we suggest the occurrence of two clinical presentations of the disease: non-complex (endogenous origin) and complex FMFH (exogenous origin). In the latter case, because of the delayed remission associated with a higher percentage of persistent mammary growth and mortality, we recommend using antiprogestin whenever no reduction of the mammary glands is observed after OVH (see the supplementary material).…”

Objectives The aim of this study was to evaluate the effectiveness of ovariohysterectomy (OVH) on feline mammary fibroepithelial hyperplasia (FMFH) treatment, as well as the influence of previous injectable progestin on clinical signs and treatment of FMFH. Methods Seventy-nine female cats diagnosed with FMFH between 2014 and 2018 were included. The animals were distributed as follows: (1) treated only with OVH (TA) or OVH plus antiprogestin (TB); and (2) no administration (G1) or previous administration (G2) of injectable progestin before FMFH diagnosis. Data regarding clinical signs of FMFH, occurrence of persistent mammary growth after OVH, and time until complete remission of FMFH post-surgery were recorded and evaluated. Results Mastectomy was not performed in any cat during the study. TA was adopted in 71/79 (89.9%) cases, with 42/71 (59.2%) from G2 and 29/71 (40.8%) from G1. TB was adopted in 8/79 (10.1%) cats, all from G2. Total remission of FMFH was observed in 73/79 (92.4%) cats, with six animals from G2 having died (n = 6/79 [7.6%]). The time until complete remission of FMFH was higher ( P <0.0001) in cats from G2 than from G1. Moreover, animals from G2 had a higher percentage of persistent mammary growth after OVH ( P <0.001) and a tendency to higher mortality ( P = 0.052) compared with G1. Conclusions and relevance Previous treatment with injectable progestin may result in a more complex clinical presentation of FMFH. Ovariohysterectomy is a good treatment option for FMFH when there is no interest in breeding the queen. Treatment with antiprogestin is recommended, especially if persistent mammary growth is detected after OVH.

“…Contudo no quadragésimo primeiro dia houve recidiva da mastopatia e assim optou-se por administrar o aglepristone, com demonstração de resultado satisfatório. Ao contrário da abordagem típica pela incisão da linha média, o ideal é que a OSH seja realizada a partir de celiotomia pelo flanco ou ainda por videolaparoscopia assistida, devido ao grande volume mamário (Filgueira & Reche-Júnior, 2012;Colomé et al, 2014).…”

RESUMO -A hiperplasia fibroepitelial e a displasia cística são proliferações não neoplásicas da glândula mamária felina. Embora sejam benignas, possuem o carcinoma como principal diagnóstico diferencial. Objetivou-se estabelecer o perfil clínico-epidemiológico e terapêutico das neoformações mamárias não neoplásicas de gatas domésticas, no sentido de auxiliar aos clínicos veterinários no manejo destas mastopatias. A obtenção das informações, de forma retrospectiva, ocorreu por meio de fichas do Hospital Veterinário da Universidade Federal Rural do Semi-Árido. Foi colhida informação da anamnese, aspecto clínico das lesões, diagnóstico microscópico, terapia utilizada e resposta clínica. Os dados foram distribuídos em frequências. Verificou-se que a maioria das alterações (91%) correspondia à hiperplasia fibroepitelial, em contraste com apenas um (9%) caso de displasia cística. A citologia confirmou todas as situações de hiperplasia fibroepitelial, enquanto o diagnóstico definitivo da displasia cística foi obtido somente pela histopatologia. Grande parte das gatas estudadas possuía idade inferior a um ano, sendo usualmente não ovariectomizada e já submetida à terapia com progestágenos. O sinal clínico mais comum foi à cianose local. Em 90% das fêmeas com hiperplasia fibroepitelial mamária, o tratamento primário equivaleu à administração de fármaco antiprogestágeno (aglepristone). Após a regressão do tecido mamário, as pacientes foram submetidas à ovariossalpingohisterectomia. Para a displasia cística, estabeleceu-se a associação da esterilização cirúrgica com a mastectomia. Para todas as situações, as distintas terapias promoveram a remissão definitiva das mastopatias. Os dados obtidos tornam-se fundamentais para a abordagem clínica e terapêutica das pacientes felinas acometidas por neoformações não neoplásicas da glândula mamária.Palavras-Chave: Estudo retrospectivo; Felis catus; mastopatias hiperplásicas e displásicas. ABSTRACT -The fibroepithelial hyperplasia and cystic dysplasia correspond to feline mammary gland nonneoplastic proliferations. Although benign, they have the carcinoma as the main differential diagnosis. The study aimed to establish the clinical-epidemiological and therapeutic profile of nonneoplastic mammary neoformations of domestic cats, in order to help veterinary clinicians in the management of feline mastopathies. Information was obtained retrospectively from the Veterinary Hospital of the Semi-Arid Rural Federal University clinical records. Historical information, clinical appearance of the lesions and microscopic diagnosis were collected, besides the therapy used and the respective clinical response. The data were distributed in frequencies. It was found that most disorders (91%) corresponded to fibroepithelial hyperplasia, in contrast with one (9%) case of cystic dysplasia. Cytology was enough to confirm all cases of fibroepithelial hyperplasia, while the cystic dysplasia definitive diagnosis was obtained only by the histopathological exam. Many of the cats studied were under one year old,...
