Neurofibroma in a dog on chest cavity




Neurofibroma is a benign nerve sheath tumor in the peripheral nervous system, a genetically-inherited disease, and can result in physical disfiguration and pain to cognitive disability. Neurofibromas arise from Schwann cells. Neurofibromas have been subdivided into two broad categories: dermal and plexiform. Dermal are associated with a single peripheral nerve, while plexiform are associated with multiple nerve bundles.
Dermal Neurofibromas
Dermal neurofibromas continue to increase in number and size throughout life. They look like lumps on or under the skin.
Plexiform Neurofibromas
Plexiform neurofibromas are often congenital defects, and can be very large and can cause pain, disfigurement, neurological and other clinical deficits. These tumors are commonly treated with surgical removal. Dermal neurofibromas are not usually removed unless they are painful or disfiguring, because there are generally so many of them and they are not dangerous.

These are the photos of a street pet dog and i have already written about her story. I feel so sorry for her as she came to me in quite late stages. CT scan revealed that growth was deeply attached with intercostal muscles and was deeply rooted in the thoracic cavity. i tried but couldn't help her too much.
