Jaw tumour. Light micrograph (LM) of a section through tissue from a jaw showing an ameloblastoma. Ameloblastoma is a rare disorder of the jaw involving abnormal tissue growth. The resulting tumours or cysts are usually not malignant (benign) but the tissue growth may be aggressive in the involved area. On occasion, tissue near the jaws, such as around the sinuses and eye sockets, may become involved as well. The tissues involved are most often those that give rise to the teeth so that ameloblastoma may cause facial distortion. Malignancy is uncommon as are metastases, but they do occur. Treatment is with surgical removal of the tumour. Magnification: x100 when printed at 10 centimetres wide. Human tissue.
