Abstract
Due to the increasing popularity of minipigs as pets, the frequency of presentation to the veterinarian is increasing as well. In addition to routine measures such as claw trimming, vaccination and antiparasitic treatment, diagnostics, and therapy of diseased minipigs are also common activities in the veterinary practice. In recent years, we have noticed more and more pathological changes of the female genital tract of uncastrated minipigs. There are also some case reports available in the international literature in this regard. The following case report describes the diagnostic procedures and ovariohysterectomies of 2 13-year-old female minipigs in detail. In these cases, uterine adenocarcinoma, and uterine carcinoma, respectively, combined with cystic endometrial hyperplasia (CEH) of the endometrium were diagnosed.

Abstract
OBJECTIVES The primary objective of this study was to describe the clinical management and surgical treatment of production size pigs (PrdP) with uterine neoplasia. A secondary objective was to compare tumor diagnoses as well as short- and long-term survival between PrdP and a published report of pot-bellied pigs (PBP) following surgical intervention. STUDY DESIGN Retrospective clinical study. ANIMALS OR SAMPLE POPULATION Client-owned PrdP (n = 13) treated with exploratory celiotomy ±ovariohysterectomy for uterine neoplasia. METHODS Medical records from a university hospital were reviewed for historical treatment, presenting complaint, clinical signs, diagnostics, surgical intervention, pathology, and outcome. An online owner survey was performed for follow-up. The novel PrdP cohort was compared to a previously published PBP cohort for differences in tumor diagnoses, surgical complications, and survival. Descriptive statistics, Fischer's exact tests and odds ratios were reported. RESULTS PrdP were affected by uterine leiomyoma (4/11), leiomyosarcoma (2/11), adenoma (1/11), adenocarcinoma (3/11), and carcinosarcoma (1/11) with no difference in tumor types between PrdP and PBP. PrdP surviving to hospital discharge (6/13) survived at least 1 year postoperatively, with median follow-up of 16 months (14-60 months). PrdP were less likely than PBP to survive in the short-term despite similar frequencies of marked intraoperative hemorrhage. PrdP and PBP had comparable rates of long-term survival following hospital discharge. CONCLUSION PrdP are afflicted by similar uterine neoplasia diagnoses as PBP, but they have lower rates of short-term survival to hospital discharge with surgical treatment. CLINICAL SIGNIFICANCE/IMPACT PrdP have a guarded prognosis for survival to hospital discharge when operated for uterine neoplasia.

Abstract
Background The present paper reviews the occurrence of neoplasms in swine and presents a case series of 56 tumors submitted to the Slaughterhouse Support Network (Servei de Suport a Escorxadors [SESC] IRTA-CReSA]) from slaughtered pigs from 1998 to 2018 (April) in Catalonia (Spain). The aim of the study was to describe the spectrum of spontaneous neoplastic lesions found in slaughtered pigs and to compare the reported tumor cases with previous published data. Lymphoid neoplasms were characterized and classified using the WHO classification adapted for animals. Results The most reported neoplasm during this period was lymphoma (28). Within lymphomas, the B-cell type was the most common, being the diffuse large B-cell lymphoma (15/28) the most represented subtype. Other submitted non-lymphoid neoplasms included melanoma (7), nephroblastoma (3), mast cell tumor (2), liposarcoma (2), osteochondromatosis (2), papillary cystadenocarcinoma (1), peripheral nerve sheath tumor (1), lymphoid leukemia (1), fibropapilloma (1), hemangiosarcoma (1), hepatoma (1), histiocytic sarcoma (1), pheochromocytoma (1) and osteosarcoma (1). Conclusions The existence of a well-established Slaughterhouse Support Network allowed the compilation of comprehensive data for further epidemiological and pathological studies, particularly about less commonly reported lesions in livestock such as neoplasms in pigs. Supplementary Information The online version contains supplementary material available at 10.1186/s40813-021-00207-0.

Abstract
In contrast to the diverse studies on human papillomaviruses (HPVs), information on animal PVs associated with anogenital lesions is limited. In the animal kingdom, papillomas occur more commonly in cattle than in any other animals, and diverse types of Bos taurus papillomaviruses (BPVs) exist, including the very recently discovered BPV type 29 (BPV29). From this perspective, we will review previous studies describing PV types associated with anogenitals in animals, with a focus on BPVs. To date, two classical BPV types, classified into Deltapapillomavirus (BPV1 and BPV2) and Dyokappapapillomavirus (BPV22), and two novel Xipapillomaviruses (BPV28 and BPV29) have been identified from anogenital lesions and tissues of the domestic cow. Due to the limited reports describing anogenital-associated PVs in animals, the relationships between their phylogenetic and pathogenetic properties are still undiscovered. Animal studies are valuable not only for the veterinary field but also for human medicine, as animal diseases have been shown to mimic human diseases. Studies of anogenital-associated PVs in animals have a positive impact on various research fields.

Abstract
Uterine leiomyomas, commonly termed fibroids, clinically affect approximately 25% of women of reproductive age in the United States, with a subclinical incidence as high as 77%. The pathogenesis of fibroid formation remains poorly understood, due in large part to the lack of a suitable animal model. This retrospective study characterizes the clinical, gross, and histopathologic features of similar, spontaneously occurring uterine tumors in potbellied pigs. Medical records available through a local Potbellied Pig Spay/Neuter Program, pig sanctuaries, and the Duchess Fund database were reviewed for evidence of reproductive disease or surgery. One-hundred and six female potbellied pigs were evaluated and uterine neoplasia was identified in 17 animals; tissues were available for 13 of these. Uterine leiomyoma was diagnosed in 11 of 13 cases, leiomyosarcoma in 1 of 13 cases, and undifferentiated sarcoma in 1 case. Pigs presented with clinical signs including abdominal distension or vaginal bleeding or were subclinical and identified during ovariohysterectomy. Tumors ranged from microscopic to 45 kg, were often multiple, and primarily involved the uterine horns. Hematoxylin and eosin and trichrome-stained sections were evaluated for morphological features of human and animal leiomyomas; immunohistochemistry to detect smooth muscle actin was also performed. The cellular pattern/morphology and variable degree of fibroplasia of the leiomyomas were similar to that reported for human fibroids. These results support further investigation of uterine leiomyomas in potbellied pigs as a potentially valuable animal model for studying human fibroids.

Abstract
Two Vietnamese pot-bellied pigs ( Sus scrofa) were euthanatized after they developed abdominal distension. Necropsy of both pigs revealed large myometrial neoplasms and cystic endometrial hyperplasia. Multiple discrete smaller myometrial neoplasms were also observed in one pig; however, distant metastases were not observed in either animal. The tumors were diagnosed as leiomyomas on the basis of histologic examination and immunohistochemistry. This is the first detailed report of uterine leiomyomas in swine, and it is suggested that this diagnosis may become more common as more aging pigs are examined.

Abstract
The clinical, pathological, and immunohistochemical findings associated with a vaginal leiomyosarcoma in a 12-year-old, Senepol breed of cow from Uberlândia, Minas Gerais are described. The animal had a large ulcerative neoplastic growth that originated between the base and the left-lateral vaginal wall. Histopathology revealed a tumor formed by muscle-like cells that demonstrated cellular pleomorphism, anisokaryosis, prominent and multiple nucleoli, with rare tumor giant cells. The neoplastic growth invaded adjacent adipose tissue, and contained areas of hemorrhage with discrete accumulations of inflammatory cells. By immunohistochemistry, most neoplastic cells expressed actin, while immunoreactivity to desmin was weakly expressed. These findings support a diagnosis of leiomyosarcoma, and represent the first description of a bovine vaginal leiomyosarcoma from Brazil.

Abstract
Advances in our understanding of ovarian cyclicity, pathogenesis of subfertility and/or infertility and reproductive pathology in food animals have frequently entailed examination of abattoir material. Despite the fact that most lesions in ewes are likely to be of relatively minor significance to fertility, results of previous studies suggest that lesions of the female reproductive system may represent a significant source of loss to sheep husbandry. The objective of this paper is to review the pathophysiology, the effects on reproductive efficiency and the key gross and histological diagnostic features of congenital and acquired pathology of ovary and tubular genital organs in ewes.

Abstract
The clinical and pathology features of a cow with uterine adenocarcinoma and multiple metastasis are described. Weight loss, inappetence, mild respiratory signs, and reduced milk yield were evident on clinical examination. Grossly deformed uterus, enlarged iliac lymph nodes, and rosary arranged nodules in the mesentery were felt by rectal palpation. Right side laparotomy revealed numerous small masses covering the omentum, and mesentery. Euthanasia was performed. Necropsy and histopathology exam revealed a uterine adenocarcinoma with multiple pulmonary, liver and mesentery metastasis. Uterine adenocarcinoma with metastasis should be included in the differential diagnosis of cows showing weight loss and mild respiratory distress and palpation of numerous firm nodules in the mesentery should be suggestive of neoplasias' metastasis.

Abstract
Leiomyomas are benign tumours, which are frequently found in animal species. However, the presence of leiomyomas in domestic ruminants has been rarely reported, especially in sheep. This report describes the pathological and immunohistochemical characteristics of a leiomyoma in the uterine body of a sheep and discusses the different aetiological causes. This is the first description of a leiomyoma in sheep in Spain.

Abstract
Leiomyosarcoma was diagnosed in the uterus surgically removed from a 3-year-old pet Suffolk ewe with a history of bleeding from the vulva, spontaneous lactation, and nursing behavior. The uterus contained multiple well-circumscribed, soft, intraluminal polypoid masses of variable sizes (0.5-4 cm). The masses were red, with white, smooth, and glistening cut surfaces. Histologically they comprised variably dense sheets of moderately pleomorphic, plump spindle cells embedded in richly vascularized stroma. The mitotic index was usually low (0-1/high-power field), but in some polyps there were up to 10 mitoses/high-power field. Neoplastic cells stained positive for alpha smooth muscle actin (alpha-SMA) by immunohistochemistry. Ultrastructural features of neoplastic cells included the presence of basal lamina, scant microfilaments, contracted nuclei with blunt ends, and flat intercellular junctions. Uterine leiomyosarcoma was diagnosed based on cellular morphology and atypia and positive immunohistochemistry for alpha-SMA.

Abstract
Three cases of bovine, ovarian epidermoid cysts were diagnosed as unilateral benign lesions in three out of 1,971 cows at slaughter. A stratified, cornifying, and squamous epithelium without associated skin adnexal structures or tissues from other embryonic tissue layers lined the cysts. The cysts were small, usually multiple, and contained keratin debris. Macroscopically, they resembled abscesses. These are benign, congenital lesions that are a separate entity from dermoids and teratomas, and they appear to have a higher incidence in cattle with Bos indicus breeding.

Abstract
An aged Saanen doe was euthanized following repeated severe hemorrhage from the vulva. Necropsy examination revealed mural thickening of tubular genitalia with firm, protruding intralumenal masses containing blood-filled cavitations, and effacement of normal cervical architecture. Histologically, uterine and cervical masses comprised a variably dense population of mildly pleomorphic spindle cells forming interlacing streams supported by variably dense collagenous stroma. Immunoperoxidase staining of neoplastic cells was positive for muscle-specific actin, supporting the diagnosis of low-grade leiomyosarcoma. Months later, the doe's twin was likewise euthanized due to persistent bleeding from the vulva associated with a large vulvar mass having histopathologic features similar to those of the previous case. The clinical, gross, and histologic findings are similar to five cases of caprine genital leiomyosarcoma identified in retrospectively analyzed case material. Analysis of caprine tumor accessions over 20 years demonstrated a significantly higher incidence of genital leiomyosarcoma within the Saanen breed.

Abstract
A 4-year-old Holstein cow developed a large neoplastic mass, which was formed in the deep soft tissue of the neck and removed surgically. The neoplasm was shown to be a smooth muscle tumour by the presence of alpha smooth muscle actin and fine intracytoplasmic filaments with focal densities. This malignant neoplasm showed extensive areas of necrosis and haemorrhage, high cellularity, marked pleomorphism, atypical giant cells and numerous mitoses with occasional abnormal figures.

Abstract
A review is given of the comparative pathology of endometrial carcinomas regarding the incidence, the morphology, and the relation with endometrial hyperplasia. Compared to man, endometrial carcinomas in animals are fairly rare, except in rabbits, in cattle, and in a stock of Han: Wistar rats. In rabbits the endometrial carcinomas are mostly primary multiple and present in both horns. Histologically they are almost always adenocarcinomas. The histological structure can vary considerably with regard to the degree of differentiation. In cattle the endometrial carcinomas are mostly singular. Histologically they are mostly adenocarcinomas, often accompanied by formation of much dense fibrous tissue. In rats the endometrial carcinomas are mostly primary multiple adenocarcinomas. In man as well as in the rabbit and in the rat, relationships have been described between endometrial hyperplasia and endometrial carcinoma. It is striking that in the dog, a species in which endometrial hyperplasia very often occurs, endometrial carcinomas should be rare. The endometrial carcinoma in the rabbit as an animal model for human endometrial carcinoma is discussed extensively. In both species there are signs indicating relationships between endometrial carcinomas and sex hormones, especially oestrogens. The incidence in rabbits is very high. Endometrial carcinomas in rabbits can be transplanted subcutaneously in the same rabbit. They can also be cultured in vitro. Moreover the rabbit is a suitable species to study the progesterone/progesterone-receptor complex by determining the synthesis of the progesterone-induced protein uteroglobin which may be important in studying endometrial carcinomas. Uteroglobin is a good marker for a functional 'Progesterone-PR-DNA-mRNAug-Uteroglobin- System' (or PUG-System).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Of a total of 1445 sows, tumors were detected in the uterus of 11 animals and in the cervix/vagina of 1 animal. Tumor-like lesions were detected in the ovary of 56 animals. The incidence of tumors was higher than that mentioned in the literature, possibly because of the relatively high age of the sows (mean parity of 6.8) and the accuracy of investigation. Several tumors would not have been detected during routine slaughter examination. The uterine tumors were diagnosed as leiomyoma (6), fibroma (3), cyst-adenoma (1) and fibro-leiomyoma (1). The cervical/vaginal tumor appeared to be a fibroma. The ovarian lesions could not be satisfactorily classified. They consisted of connective tissue, blood vessels, and granulosa cells, which were present in variable quantities in different ovaries and in different sides of the same ovary. Sows with tumors were older than the mean determined age at slaughter (parity 6.8). Sows with uterine and cervical/vaginal tumors had a parity of 11.6; sows with ovarian lesions had a parity of 9.0. Sows with uterine- or a cervical/vaginal tumor were often slaughtered for infertility reasons.
