RESUMO
Background: Ovarian torsion is a condition which the ovary and the ovarian pedicle twist around the ovary suspensory ligament. No report regarding this condition was reported. The aim of the report was to describe a case of unilateral ovarian torsion in a 2-year-old primipara Golden Retriever dog.Case: A 2-year-old female primipara Golden Retriever dog weighting was referred to the Veterinary Hospital, for purulent vaginal discharge evaluation. The dog was presenting anorexia, weight loss, and intermittent diarrhea and vomiting. A cesarean section was performed nine months before her presentation and the oestrus cycle was recorded six months after the cesarean section. Discomfort was observed during the palpation of the abdomen and purulent vaginal was observed. Vaginal swab was performed and followed by cytological examination. The ultrasonographic examination was consistent with pyometra. The ovariohysterectomy was performed and were observed torsion of the left ovary. The histopathological examination of the left ovary and uterus were consistent with ovary necrosis and pyometra. Ten days after surgery the vaginal discharge had resolved and the sutures were removed. Six months postoperatively the dog revealed no further abnormalities. Grossly, the left ovary had firm consistency, dark red surface and 8 cm diameter. The histopathology examination findings were consistent with a diagnosis of diffuse necrosis of left ovary due to ovarian torsion, and uterine suppurative inflammatory process - pyometra.Discussion: Ovarian torsion is uncommon in small animals, but can be observed high incidence in pregnant female dogs than in non-pregnant ones. The 360º an asynchronous ovarian torsion described in the present case is also an unusual condition in primipara female dogs due to the smaller stretching of the ovary suspensory ligament. The ovarian torsion is considerate an emergency condition due to acute abdominal pain.[...](AU)

Trichoblastoma is a cutaneous benign neoplasia which is derivate of primitive hair follicles and have epithelial and mesenchymal elements. The study aimed to describe a case of an unusually aggressive trichoblastoma in a male dog, Maltese breed, 7 months old and 7 kg of body weight, with history of increased and rapid growth volume in frontal head region. The neoformation was ulcerated; hard consistency and not adhered; presence of alopecia and pink color; and no pain during palpation. The blood count, serum biochemical tests, urinalysis and imaging exams revealed no changes. On the cytological examination was observed the presence of basal epithelial cells with monomorphic nuclei and basophilic cytoplasm. The treatment was surgery with total excision of the neoformation. Twenty-one months after the surgical procedure was not observed any signs of recurrence and metastasis. Even rare in dogs and with age under 6 years, it was identified a macroscopically aggressive trichoblastoma in young dog with 7 months old, with histopathological features similar to that of adult dogs, and was the first case reported in Mozambique. The total surgical excision of the trichoblastoma was the treatment for this case report.(AU)
O tricoblastoma é uma neoplasia benigna cutânea derivada do folículo piloso primitivo, possuindo elementos epiteliais e mesenquimais. O trabalho teve como objetivo descrever um caso raro de tricoblastoma agressivo, em um cão macho da raça Maltês, sete meses de idade e pesando 7 kg, com histórico de aumento de volume, de crescimento rápido, em região frontal da cabeça. A neoformação apresentava-se ulcerada; de consistência dura e não aderida; presença de alopecia e coloração rósea; e ausência de dor à palpação. O hemograma, os exames bioquímicos séricos, urinálise e exames de imagem não revelaram alterações. No exame citopatológico foi observado presença de células epiteliais basais com núcleo monomórfico e citoplasma basofílico. O tratamento consistiu no procedimento cirúrgico por excisão total da neoformação. Vinte e um meses após o procedimento cirúrgico, não foi observado quaisquer sinais de recidiva e metástases. Visto que o tricoblastoma é raro em cães e com idade inferior a seis anos, o mesmo foi identificado na sua forma macroscopicamente agressiva em cão jovem de sete meses de idade, com características histopatológicas similares à dos cães adultos, sendo o primeiro caso reportado em Moçambique. A exérese total do tricoblastoma foi o tratamento para o presente relato de caso.(AU)
