A one-day-old male Holstein calf was presented with a palpable subcutaneous mass, extending from the parotid to the orbital region, involving entire the right side of the face and a bulky flabby mass on the tongue. Histological examination confirmed the subcutaneous lipoma and infiltrative lingual myxoma. In this report, clinical and detailed histhopathological findings of congenital infiltrative myxoma are described in a newborn calf and coincidence with facial lipoma is reported for the first time.

Introduction:
Tumours in calves, like those in children, are relatively uncommon. These tumours are interesting because of their occurrence early in life, indicating a probable congenital nature(Misdorp, 2002). Myxoma is a benign neoplastic process (Okamoto et al., 2002) of fibroblast or multipotential mesenchymal cells origin distinguished by its abundant myxoid matrix rich in mucopolysaccharides (Maxie and Jubb, 2007; Meuten, 2002). Myxoma is extremely rare in cattle (Misra et al., 1981). It usually occurs in adult or aged animals as solitary or infiltrative soft masses (Maxie and Jubb, 2007). In a retrospective study of 6,706 cattle during the period of January 1964 to December 2008, only one case of myxoma was detected among 586 tumors in Brazil (Lucena et al., 2011). Etiology of this tumor is unknown (Allen, 2000). Genetics, envorimental factors, carsinogenic drugs or miscellenous toxic substances are among the probable causes of this neoplasm (Yeruham et al., 1999). Tumors arising from subcutaneous lipocytes occur in all species. Lipomas are most common in dogs and may be multiple. In all species, they usually occur in adult and aged animals and are most ...

The condition known as Equine Metabolic Syndrome (EMS) gains its name from the similarities it shares with a widely known disease in humans: Metabolic Syndrome or better known as Type II Diabetes. The condition was suggested in 2002 by Johnson of the University of Missouri Veterinary Medicine College. He proposed insulin resistance, obesity of the neck, tail head and sheath/mammary gland area, and an increased predisposition to laminitis were symptoms of a clinical syndrome in horses and ponies....
... occurs in the shin, thigh, and upper arm, but not explicitly. This can be localized, meaning in one place on the body, or metastic, having spread to other parts. This cancer is more common in male teens than any others. For the greatest part, teens suffering from osteoarcoma do recover. The survival rate for this cancer, if localized, is 70-75%. ("Osteosarcoma" Teens Living with Cancer.) If this cancer spreads, it is customarily to the lungs of the patient. X-rays are generally the first diagnostic test. Biopsies are performed to make the final and certain diagnosis. This disease’s treatments include chemotherapy, and surgery, ordinarily together. Radiation, though uncommon, can be used as a treatment for osteosarcoma. After treatments, it is recommended the patient receives follow up care to monitor the cancer in case it returns or any side effects are present.

Dysplasia causes abnormal wear of the joints, which are very common in large dog breeds; gastric dilation and volvulus (bloat) caused from over eating, is also an occurrence known in this breed of dog. The swollen and twisting of the stomach, causes restriction of blood flow to several major organs like the heart.
Envision, a tumor so repulsive, it violates the very laws of physiology, turning normal tissues at odds with their own nature. According to Merriam Webster, a teratoma is defined as a tumor derived from more than one embryonic layer and made up of a heterogeneous mixture of tissues, such as epithelium, bone, cartilage, or muscle. The name teratoma, originates from the ancient greek prefix of terato, meaning monster, combined with the suffix oma, meaning mass. Therefore, it can be interpreted, the phrase teratoma, denotes a monstrous mass. Indeed, teratomas, are of grotesque quality, seeing as they are not limited by normal anatomical boundaries. Even more, they may even contain hair, teeth, fat, bone, and sometimes complex organs (see fig 1).

Though cats are less likely to get cancer than dogs, there are many different types of cancers that a cat can contract. Some of the most comon are Lymphoma, Skin Cancer, Gingiva Oral squamous Carinomas or mouth cancer, and Osterocacroma. Lymphoma is a type of cancer that starts in the Lymphocyte Cells, a type of whote blood cell. Lymphocyte Cells play an important part in the immuine system. Lymphoma is found to be responsible for around 90% of blood cancers and about 33% of all tumors in cats. Its also the most common cause of hypercalcemia in cats. (Science Weekly, 2012) Skin cancer in cats often appears like a white plaque or a raised bump on the skin. The bump will often ulcerate with occasional bleeding. These type of carcinomas are usually malignant, early detection and treatment is best. These cancerous cells can easly spread just like any other cancer to other organs. Skin cancers are more likely in cats that live in high altitudes or cats with light, esspecially white, coats. (Crain, D, 2005) Gingiva Oral squamous Carinomas, or mouth cancer, is particularly deadly, moving quickly though the body, with usual fatal results. These tumors grow very rapidly and usually invade to nearby bone and tissue. These carcinomas are usually seen in oldercats. (PetMD, 1999- 2014) Osteosacroma is the most common milignant bone tumor in veterinary practice. This cancer is especially painful, the most comon places for these tumors are the humerus, femur, and ti...
The tissue was fixed overnight in, the tissues were stained Thick sections for light microscopic (LM) survey were stained with toluidine-blue. Thin sections for EM were stained with uranyl acetate and lead citrate, and examined using a Zeiss EM 109 transmission electron microscope. He observed Apoptotic keratinocytes in 95 of the 106 cases. Electron microscopic study of 25 EM blocks of 18cases revealed seven AKs.

The condition may be present at birth or in the very early years of the child’s life. Besides the obvious polygon shaped scaly patches on the skin(gray, white, brown) other notable and identifiable symptoms include itchy, dry, or thick skin. However, Mr.Anders and Mrs.Anders, I am not trying to send you into a panicked alarm as there is much to be done for the child in the future. Ichthyosis Vulgaris does not affect life expectancy in any manner and although there is no cure for the condition certain treatment can help manage the
Most doctor do not know much about Systemic Mastocytosis and if they do it is only a little bit. After a while the doctors wanted to keep a close eye on me and my siblings. My brother and I only showed signs of the disease. However, my brother was growing out of the disease and signs of the disease like most kids, who show signs of SM. I on the other hand was not. I have one major sign of SM, which is Dermatographia. Dermatographia is a condition in which lightly scratching your skin causes raised, red lines where you’ve scratches, which is basically hives. But this is not limited to scratches. You could be scratched, hit, or, this has happened to me before, I sat a really cold hold and developed hives. The hives to go way by the time 30 minutes past. Although I do show signs of SM I have not be officially diagnosed. My dog just so happened to have a tumor in her leg. When the vet sent it in to be tested, they found that it was mast cells. My dog has staged two cancer and the same disease as my dad, what is the
