Pheochromocytoma in Dogs: 61 Cases (1984-1995) Paul Y. Barthez, Stanley L. Marks, Je nny Woo, Edward C. Feldman, and Mark Matteucci This report presents the clinical, laboratory, imaging, and pathologic findings in 61 dogs with pheochromocytoma by retrospective evaluation of medical records. The mass was characterized ultrasonographically as solid in three dogs (all leiomyomas), solid with cystic component in four dogs (two adenocarcinomas, one leiomyoma, and one fibroleiomyoma), and cystic in two (both leiomyomas). Benign smooth muscle tumours are reported to be rare amongst domestic animals (Hulland, 1978): the leiomyoma (fibroleiomyoma) is the most frequent tubular genital tract tumour in the dog and cat, constituting approximately 80 per cent of the tumours of the uterus, vagina and vulva in the bitch. Malignant uterine tumors reported in the dog include adenocarcinoma, endometrial carcinoma, lymphosarcoma, hemangiosarcoma, metastatic transmissible venereal tumor, and metastatic dysgerminoma. In: International Conference on One Health and 24th VAM Congress 2012, … The most common smooth muscle tumor of the uterus … Define fibroleiomyoma. Hyperechoic foci in the mass were observed in three dogs. Fig 5: Dog-Vaginal mass-Masson’s Trichrome staining method-Green coloration of the abundant collagen (40x) The age group of the dog correlated with the previous findings of Brodey and Roszel, (1967) [2] who reported that that the average age group of affected dogs tends to be around 10 to 12 years. leiomyofibroma. clinique des animaux de compagnie et des équidés (DCA) > Obstét. Leiomyomas are benign soft tissue neoplasms that arise from smooth muscle; they were first described by Virchow in 1854. Microscopic Findings The examined sections of urinary bladder were extensively ulcerated. These include obesity, arthritis, skin disorders, overgrown tusks and overgrown claws. 66,69 These dogs have multiple firm, haired masses all over their bodies. The prevalence of Leiomyomas in female genital tract is 2.4% of all canine neoplasia [Susaneck, 1981; Barrett and Theilen, 1977; Hulland, 1978]. 30104773. leiomyoma [li″o-mi-o´mah] a benign tumor derived from smooth muscle, most often of the uterus (leiomyoma uteri). eng.

Unusual Case of a Torted Mesenteric Fibroid leiomyoma), fibroleiomyoma , a fibrous tissue and smooth muscle tissue tumor and fibroma, a fibrous tissue tumor. Clinical findings of three pedunculated vaginal masses at the vaginal orifice were observed. Mesenchymal intestinal tumours such as fibroma and fibroleiomyoma occur very rarely and there are few reports of their occurrence in the dog (JUBB et al., 1993). The dog was reassessed, three months after surgery and then periodically for a year without any recurrence. Indications for vaginectomy include vaginal tumors (leiomyoma, fibroleiomyoma and leiomyosarcoma), polyps, vaginal prolapses etc. Other benign uterine tumors reported include fibroma, fibroleiomyoma, fibromyoma, fibroadenoma, adenoma, lipoma, angiolipoleiomyoma, and endometrial polyps. In the present research, the findings revealed that the incidence of tumors affecting skin and soft tissues was highest in bovines when compared to other types of tumors. Radi 9 also reported a case of vulvar lipoleiomyoma in a bitch spayed two weeks prior to excision of the mass. fibroma, leiomyoma, fibroleiomyoma, and inflammatory polyp. Although these tumors are the most common uterine neoplasia in humans (Crum, 1999) and are relatively frequent in other animal species and among other domestic animal species, but uterine leiomyomas are most commonly reported in dogs (Dhoke et al., 2017). The average age of dogs with gastric spindle cell tumors diagnosed as leiomyosarcoma was reported to be 7 years, ... the mean age of the dogs was 12.5 years for leiomyoma, but no information was available regarding the age of dogs with fibroleiomyoma. vaginal process. Most mammary tumours arise in middle-aged intact females with a peak incidence between 6 and 10 years of age (Egenvall et al 2005).Mammary cancer in males is rare (<1% of all mammary tumours occur in males) (Lana et al 2007), and female dogs are 62 times more likely to develop mammary gland tumours than male dogs (Saba et al 2007).In a recent study of eight male dogs with mammary … In some cases your dog may show symptoms such as difficulty urinating, vaginal discharge, licking at … bizarre leiomyoma epithelioid leiomyoma. On histopathologic examination these nodules are composed of dense, irregular collagen. A 15 year-old, intact female, Pomeranian dog was presented to University Veterinary Hospital (UVH), Universiti Putra Malaysia (UPM) with a complaint of vaginal mass growth for the pass one year. des anim. Keywords: vagina; fibroleiomyoma; pathology; cow Fibroleiomyoma are tumours which consist of an admixture of smooth muscle and connective tis-sue, and generally have been reported in the female reproductive tract of dogs and cats (Brodey and Roszel, 1967; Cooper and Valentine, 2002; Pulley and Stannard, 1990). The incidence of tumors in bovines is relatively increasing which undermine the productivity of animals. EXAMPLES • Medroxyprogesterone acetate (MPA), proligestone and hydroxyprogesterone hexanoate are synthetic progestins that should not be used in small animal reproduction. (There are several types of smooth muscle tumors, including leiomyoma; fibroleiomyoma, a fibrous tissue and smooth muscle tissue tumor; and fibroma, a fibrous tissue tumor.) Megestrol acetate (MA) is a synthetic progestin registered for use in bitches and queens. de comp. Fibrolipoleiomyoma in the present case occurred in spayed bitch. Hyperechoic foci in the mass were observed in three dogs. Smooth muscle tumors (leiomyoma, fibroleiomyoma, fibromyxoleiomyoma, adipoleiomyoma, leiomyosarcoma) The most common neoplasm of the wall of the uterus in the dog is the smooth muscle tumor (leiomyoma). The most common tumors arise from smooth muscle or collagen-producing cells, and go by the multisyllabic names of leiomyoma, fibroma, or fibroleiomyoma. Leiomyoma in dogs also is described as hormone dependent and does not occur in spayed dogs 8. Uterine Leiomyoma in a Sheep Uterine Leiomyoma in a Sheep Corpa, JM; Martínez, CM 2010-08-01 00:00:00 Introduction A variety of mesenchymal tumours, including fibroleiomyoma, fibroma, leiomyoma and, far less commonly, their malignant counterparts, are formed in the uterus of domestic animals ( Maclachlan and Kennedy 2002 ). The surgical technique is two-folded and consists of an extended laparotomy approach with caudal ovariohysterectomy followed by an episiotomy approach with removal and reconstruction of the vaginal wall. These tumors may be located in all organs, with a higher or lower incidence in some tissues, as it will be shown. A total of 59 samples suspected for neoplasia were collected in cattle (47 samples) and buffaloes (12 samples) during 2012-2014, out of which neoplasia were diagnosed in 57 samples. In nonulcerated areas, there was hyperplasia of tran- ... Polypoid cystitis in dogs appears to have a predilection for females and presents as macroscopic hematuria.10 Mostlesions The records of nine female intact dogs with histologically confirmed uterine tumors were reviewed retrospectively, and the related radiographic and ultrasonographic signs of the lesions detected were recorded.

Vulvovaginectomy and perineal urethrostomy were performed in three dogs with extensive neoplasms of the vulva and vagina. Discussion In dogs, 86 percent of vaginal tumors are benign smooth muscle tumors, often with finger like extensions (e.g. Mesenchymal tissue neoplasms are soft tissue tumors, also known as connective tissue tumors, which are relatively frequent in domestic animals and have a high incidence in some species. Leiomyomas are benign tumours consisting of … Nodular dermatofibrosis is a pathognomonic cutaneous syndrome associated with renal cystadenocarcinomas, primarily described in German shepherd dogs. Histological examination indicated a fibroleiomyoma. Cattle occupied the second place after dogs for incidence of tumors.
