Skin Tumor (Histiocytoma) in Dogs A histiocytoma is a benign skin tumor that originates in the Langerhans cells, immune cells that function to provide protective immunity to the tissues that are in contact with the outer environment -- the nose, stomach, intestines and lungs, but mainly the skin's surface. histiocytoma is a benign skin tumor that originates in the Langerhans cells, immune cells that function to provide protective immunity to the tissues that are in contact with the outer environment -- the nose, stomach, intestines and lungs, but mainly the skin's surface.

Medical Definition of Mastocytosis Definition of Mastocytosis. Mastocytosis: A condition characterized by infiltration of mast cells into the tissues of the body. Mast cells are connective tissue cells which release chemicals including histamine that are very irritating and cause itching, swelling, and fluid leakage from cells. There are several different clinical forms of mastocytosis, including: Mastocytoma -- A benign nodular tumor on the skin rich in mast cells.

Malignant Histiocytoma Recent studies have revealed that for malignant histiocytoma, non-restricted cytotoxic T-cell line TALL-104 therapy (name of a therapy) has yielded very satisfying results. The dogs received multiple injections of lethally irradiated (40 Gy) TALL-104 cells at a dosage of 10 cells/kg with cyclosporin A, followed by monthly infusions.

What is Histotechnology? Histology is a science dealing with the structure of cells and their formation into tissues and organs. Histotechnology centers on the detection of tissue abnormalities and the treatment for the diseases causing the abnormalities. Dyes and chemicals are used in histology. It is important to know their composition, how they act, and how they react with each other. With this knowledge, combined with an understanding of tissue composition, the histotechnologist treats the tissue with these chemicals and dyes.

Lymphoma Lymphoma is any of a group of blood cell tumors that develop from lymphatic cells. The name often refers to just the cancerous ones rather than all such tumors. Symptoms may include enlarged lymph nodes, fever, drenching sweats, weight loss, itching, and feeling tired. The enlarged lymph nodes are usually painless.

Langerhans Cell Histiocytosis Langerhans Cell Histiocytosis (LCH) is a very rare form of disorder that involves clonal proliferation of the Langerhans cells, the abnormal cells that are derived from the bone marrow which are capable of moving from the skin to the lymph nodes. LCH is also known by several other names like:

A dermatofibroma is a round, brownish to red-purple growth commonly found on the legs. It is also called a histiocytoma. It can occur anywhere, but seems to favor exposed areas. Dermatofibromas feel like hard lumps under the skin. They're like an iceberg in that there is more under the skin than seen on the surface. Often these start out as red, turning later to brown, and sometimes itch.
