Pollakisuria in a dwarf goat due to pathologic enlargement of the uterus

Abstract

SUMMARYPollakisuria in adult goats can be caused by diseases of the urinary tract and by distension of parts of the genital tract leading to irritation of the bladder. Hydrometra is the most common cause of uterine distension in goats and usually can be resolved by prostaglandin injections. But other pathologies of the uterus can generate a similar syndrome. A dwarf goat was presented at the clinic with a history of chronic pollakisuria and tenesm. An initial ultrasonographic examination of the abdomen led to the suspicion of hydrometra, but treatment with injections of prostaglandin were not successful. Blood samples revealed low progesterone and high oestrogen values. A laparotomy was performed and an enlarged uterus with 1.5 L of mucous content and cystic ovaries were found and partially removed. A single solid leiomyoma was diagnosed histologically in the uterine wall. Two months later the goat's condition had deteriorated and therefore she was euthanized. Necropsy and pathohistological examination revealed the presence of a metastasized adenocarcinoma of the uterus. In this case, the pollakisuria provoqued by distension of the uterus was not caused by hydrometra, but by neoplasia. The syndrome and the pathogenesis of the adenocarcinoma in consideration of the hormonal status of the patient is discussed.

Tumor collision of uterine adenocarcinoma and leiomyosarcoma in a goat

“…Pollakiuria and abdominal straining in goats with pathologic enlargement of the uterus has been reported, and is postulated to occur secondary to mechanical irritation of the urinary bladder. 1,8,12 The present case was also diagnosed with bilateral hydroureters secondary to compression of the ureters by uterine mass lesions, which may have contributed to this patient's abdominal straining.…”

Tumors of the reproductive tract of sheep and goats: A review of the current literature and a report of vaginal fibroma in an Awassi ewe

“…In the reproductive tract, the most common sites for leiomyoma formation are the uterus, vagina, and cervix [2]. Leiomyoma was diagnosed in the cervix in a 17-year-old Toggenburg doe with a history of acute vaginal bleeding and death [14]. The tumor was found to originate from the cervix and occupy most of the vaginal lumen [14].…”

Addisonian Crisis due to Metastatic Adenocarcinoma in a Pygmy Goat

“…Necropsy findings in this doe revealed that the metastatic adenocarcinoma originated from the uterus and infiltrated multiple abdominal organs. There are a couple of single case reports of uterine neoplasia of muscle origin in goats [13,14] and one report of metastasized adenocarcinoma of the uterus [15], but no case series of uterine neoplasia are described. Based on studies in other species [16], we may assume that they are more common in the geriatric population.…”
