Mammary tumors have a high prevalence in bitches and women, and are related to high rates of morbidity and mortality. For the human species, thermography has stood out as a diagnostic tool for breast cancer. However, its clinical benefit in bitches remains unknown. Thus, the goal of the present study was to evaluate the diagnostic applicability of infrared thermography for canine mammary tumors, as well as to correlate tumor temperature with mitotic index and tumor volume. Thermographic and digital images of eight bitches with mammary neoplasms were captured. Thermograms were entered into the FLIR tools software and the temperature of 15 tumor and 15 healthy glands from the contralateral mammary chain was analyzed. There was no significant difference (p = 0.786) between the mean temperature of neoplastic (33.71°C±1.86) and healthy (33.54°C±1.59) glands. There was a negative and moderate correlation between tumor temperature and mitotic index (ρ= -0.52 p = 0.049). However, no correlation was detected between mammary temperature and tumor volume (p = 0.10). Although thermography allowed no distinction between neoplastic and healthy mammary glands in bitches, it may be promising to assess the proliferative rate of tumors. In addition, malignant neoplasms may be more often hypothermic than healthy tissue.

A histerocele é uma condição rara na espécie felina, sendo caracterizada por protrusão do útero pelo anel inguinal. O diagnóstico diferencial inclui tumor mamário, linfadenopatia, hematoma, abscesso e granuloma. Assim, exames de imagem como a ultrassonografia abdominal apresentam importante papel no diagnóstico e prognóstico da doença. O tratamento dessa condição é cirúrgico e inclui a realização de herniorrafia e ovário-histerectomia, a fim de evitar recidivas e a transmissão hereditária. O presente trabalho relata um caso de uma gata adulta com aumento de volume inguinal. Ao exame ultrassonográfico foi identificada a presença de útero herniado, contendo três fetos viáveis. O tratamento consistiu em cesariana, ovário-histerectomia e herniorrafia pela via inguinal.
