A 5-yr-old female African hedgehog (Ateleris albiventris) presented with hematuria. Vulvar culture results revealed a 4 growth of Enterococcus sp. and gamma-Streptococcus sp. susceptible to trimethoprim sulfa and enrofloxacin. Ultrasound evaluation of the abdomen revealed an unidentifiable tubular structure in the region of the reproductive tract. An exploratory laparotomy and ovariohysterectomy were performed. Pathologic studies of the uterus showed a uterine spindle cell tumor, uterine endometrial polyp, uterine adenomyosis, and a possible acute infarct resulting in uterine wall necrosis. Hematuria did not reoccur, and the hedgehog lived for another 19 mo until she died from an oral squamous cell carcinoma. To date, this is the first report of a uterine spindle cell tumor in an African hedgehog.
