Vaginal fibrosarcomas are unusual mesenchymal tumours in cows. This report describes the clinical investigation, gross and histopathological findings, surgical treatment and postoperative course of a vaginal fibrosarcoma in a cow. They are usually pedunculated and can be removed surgically. Although they do not cause infertility, they may be associated with dystocia [ 6 ]. Besides fibropapillomas, cases of squamous cell carcinoma, leiomyoma, fibroma, haemangioma, leiomyosarcoma and melanoma have also been reported in the vagina and vulva of cows [ 7 ].

Fibrosarcomas can be found in any location of the body. However, they are unusual mesenchymal tumours of the bovine vagina [ 2 , 1 , 5 ]. Fibromas, fibro-papillomas and fibrosarcomas have been reported as mushroom-shaped growths, and can be attached either by a broad base or by a long pedicle that allows part of the tumour to protrude from the vulva [ 7 ].

The mass had a wet surface with a mucoid, sanguinous discharge. Appetite was normal and the general physical examination revealed no other abnormalities. Haematological examination prior to surgery revealed a leucocytosis. The total WBC count was elevated to Other parameters, such as RBC, HGB and HCT were slightly below physiological range, which may be an indicator of mild anaemia due to the continuous haemorrhagic discharge from the mass.

The cow was restrained and the tail bandaged. Additional local infiltration anaesthesia, within the vaginal mucosa surrounding the pedicle of the tumoral mass, was performed with the same anaesthetic agent using a volume of approximately ml. Following anaesthesia, the vulva was retracted from either side with uterine forceps and the mass was revealed. An oval incision was made on the mucoasl surface at a distance of approximately 2 cm from the margin of the mass.

The total length of incision was 15 cm. Following this, blunt dissection with scissors was used to increase the depth of the incision without interfering with the edge of the mass. The major blood vessels were ligated where necessary. The defect created after the removal of the mass was closed in two steps.

Firstly, interrupted cruciate sutures were applied and, secondly, these were supported with a superficial continuous suture pattern, both using a chromic gut of USP size 2.

Postoperative parenteral antibiotics Clemipen-Strep; Topkim, Turkey for four days and local wound healing agents Bepanthene plus; Roche, Turkey were administered daily for two weeks. Sections were stained with van Gieson's and Masson's trichrome stains for the detection of collagen fibers [ 3 , 4 ].

Macroscopically, the tumoral mass was located on the ventral vaginal wall. The cut surface was homogeneously white in colour. Microscopically, the tumour was composed of spindle-shaped tumour cells forming interlacing bundles or arranged in herringbone patterns.

The cells had marked cellular pleomorphism with oval or round and slightly hyperchromatic, nuclei with abundant eosinophilic cytoplasm. The stroma of the tumour was made up of collagen fibres which were detected by van Gieson's and Masson's trichrome stains. According to these histopathological findings, the tumour was diagnosed as a fibrosarcoma.

In contrast to a fibropapilloma, the tumour did not consist of proliferating fibrous tissue with an epithelial covering of variable thickness. Fibrosarcoma with marked cellular pleomorphism and multinucleated giant cell.

Haemotoxylin and Eosin. The cow was examined two weeks after the operation, and excellent wound healing was observed with no evidence of postoperative infection. A further examination was performed following a six-month period, no evidence of regrowth of any tumoral tissue could be found and the general condition of the cow was normal.

This suggests that a favourable prognosis may be expected following proper extirpation of pedunculated tumoral masses in cows. National Center for Biotechnology Information , U.

Let's start with the female reproductive tract. Basically, it consists of two ovaries, two oviducts, two uterine horns, a uterine body, the cervix, vagina and vulva. The bladder lies below the reproductive tract and is connected at the urethral opening on the vaginal wall.

The rectum is located above the reproductive system. The vulva is the opening to the reproductive system. Its functions are the passage of urine, the opening for mating and as the birth canal. Included in the vulva's structure are the lips, vestibule and clitoris. The vulva lips are located at the opening and appear wrinkled and dry when the cow is not in heat.

A secondary sign of heat, however, is when the vulva swells and appears moist and red. The vagina, which is in. This is where semen is deposited during natural mating. Cells in the vagina and cervix secrete mucus, which lubricates the tract during insemination. The cervix itself is made of very dense, connective tissue. Thick folds and rings in the center of the cervix overlap, making it an effective barrier between the uterus and the vagina.

The cervix opens into the body of the uterus. About an inch long, the body of the uterus serves as a connection between the two uterine horns. This is where semen is usually deposited during AI.

The two uterine horns consist of layers of muscle and a heavy network of blood vessels. When a cow is bred either naturally or through AI, the uterine muscles, under the influence of the hormone oxytocin, rhythmically contract. This continuous contraction helps move the semen to the site of fertilization in the middle of the oviduct. Oviducts carry ova, the cow's eggs.

The ova are caught by the large open end of the oviduct, which surrounds the ovary. This funnel-like structure, called the infundibulum, keeps the ova from falling into the body cavity. Hair-like structures carry the ova down the oviduct to the site of fertilization.

After fertilization, the embryo travels down the oviduct and arrives in the uterus within four to five days. Over a period of time, many changes take place in a cow's reproductive system. These changes in non-pregnant, normal cows repeat about every 21 days. This regular repetition is called the estrous cycle. One ovary has a large follicle with a blister-like appearance.

This fluid-filled follicle has a mature egg ready to be released. The follicle is also producing the hormone estrogen. Estrogen, which is transported in the blood to all parts of the cow's body, causes other organs to react in numerous ways:. On Day 1, the follicle breaks, releasing the egg into the oviduct.

In the oviduct, the egg awaits sperm for fertilization. As a result, the cow no longer displays the familiar signs of heat. New types of cells — luteal cells — grow in the void on the ovary where the follicle was located. Quite rapidly, over the next five to six days, this cell growth, called the corpus luteum or CL , continues to grow.

The CL is important because it produces another hormone called progesterone, which makes the uterus ready to accept a fertilized egg and keeps the cow from coming in heat. Under the influence of progesterone, the uterus produces a nourishing substance on which the embryo grows.

At the same time, a thick plug forms in the cervix, preventing any bacteria or viruses from entering the uterus. On the other hand, if the cow is not pregnant, we do want her to come in heat again. The FSH initiates the development of a new follicle, which grows and produces large amounts of estrogen. This ultimately brings the cow back into heat. The full cycle is now complete. The average total time is about 21 days with a normal range of about days. If the cow becomes pregnant, the events of the estrous cycle are the same as those of the non-pregnant animal until Day 16 or Thus the CL remains intact and on the ovary producing large amounts of progesterone to support the developing embryo and prevent the cow from coming back in heat.

The CL remains on the ovary until the cow is at or near calving. During the first four or five days of pregnancy, the embryo moves in the oviduct toward the uterus. Once it enters the uterus, the embryo is bathed in uterine fluids and continues growing, while flowing freely there for about 30 days.

Several membranes, including the amnion, chorion and allantois, are produced by the new embryo. These eventually attach to the uterus at several points, which are called placentomes. The placentomes allow the developing calf to get nutrients from its mother and dispose of wastes via arteries and veins going in and out through the umbilical cord. At calving, the muscles in the uterus begin to contract and eventually expel the calf and membranes through a dilated cervix and vagina.

Several hormones, including progesterone, estrogen, prolactin and corticoids produced by the mother, the fetus and the placenta interact to bring about this event.

When a piece of equipment or machinery is broken, it's impossible to fix it unless you thoroughly understand the parts and how they normally work. The same is true with your cows and your reproductive management program. Understanding Females Feb 01, Management considerations for new replacement heifers.
