###Human: I was diagnosed with fibromatosis of muscle after removing a fibromatosis from my thigh. Why? ###Assistant: Hi. I have gone through the reports (attachment removed to protect patient identity). Your report does not show a definite diagnosis. I am taking fibromatosis as the final diagnosis. Fibromatosis is also called as a desmoid tumor. It is a slow-growing disease. It has an uncontrolled proliferation of fibrous tissue in the body. It starts as a slight tightening of the skin, and it slows down the functions of the structures or organs it involves. It is treated by doing surgery. Some oral medications can keep them under control.
