Retrospective study on uterine neoplasms in 36 rabbits was conducted. These were definitively diagnosed by ovariohysterectomy and histopathology. The most common chief complaint was sanguineous discharge from the vulva, followed by anorexia and swelling of the mammary gland. Urinary examination to detect hematuria, abdominal palpation, observation of the mammary gland and abdominal ultrasonography were all useful for the diagnosis of the uterine neoplasms. The most common histopathological types were uterine adenoma and adenocarcinoma, which developed even in relatively younger rabbits such as two or three years old. The third most common histopathologic type was leiomyoma, which was mostly observed in cases over five years old. The mortality was higher in serious cases with anorexia, hydrometra and/or ascites. Prognosis in the relatively shorter period after the surgery seemed to depend on the preoperative general conditions rather than the histopathologic type. If the early detection and operation could be achieved, prognosis would be better. However, spaying at the younger age must be the definitive mean to prevent uterine disorders.

A 7-month-old femal Rhodesian Ridgeback was referred for the cervical subcutaneous mass to the Veterinary Medical Center of the University of Tokyo. Thirty days before the first admission, the cervical mass was surgically removed by a practitioner but the mass with a cyst recurred at the surgical site soon after the removal. On physical examination, the mass with a size approximately 10cm in diameter was palpated on the dorsal midline of the neck. Serous fluid was drained from the selfscratched wound of the mass. The patient did not show pain by palpating the mass and was otherwise healthy. There were no abnormal findings on blood examination and on cervical and thoracic radiography. From above results, dermoid sinus of a Rhodesian Ridgeback was suspected. Magnetic resonance (MR) images revealed that the sinus seemed to extend ventrally to the nuchal ligament. After the MR imaging, the mass with the sinus reaching to the nuchal ligament was completely removed. On histology, the mass was inflammatory granulation tissue and the hair follical was demonstrated in the sinus, thus diagnosed as dermoid sinus.

Two cases of high-rise syndrome with fracture in young cats were reported. A 9-month-old spayed female and a 6-month-old male cats fell from the 6th or 7th floor and suffered from distal physeal fracture of the left femur, or right proximal ulnar fracture in addition to humeroradial and proximal radioulnar joint luxations, respectively. The surgical repair of these fracture / luxation was performed after the general condition was stabilized. Prognoses in these cases were good. Since cats with high-rise syndrome seems to be increasing possibly because of the transition of the social circumstance, it is important to take preventive measures such as education to pet owners on this syndrome.
