M72: Fibroblastic disorders

Fibroblastic disorders, as classified within the M72 group, represent a collection of conditions that stem from abnormal behavior of fibroblasts, which are cells crucial for the repair and maintenance of body tissues. These disorders might be instigated by several factors such as genetic alterations, injury, or certain diseases. Prevalent symptoms across these conditions commonly include unusual lumps or growths, pain, and, in some cases, limited movement when fibroblasts are near or in muscles or joints. The rate and path of disease progression greatly depend on the specific disorder and its location. While some of these disorders can remain relatively stable for a long period of time, others might progress swiftly causing more severe health problems. These disorders may involve multiple body systems, primarily affecting the connective tissues including skin, tendons, ligaments or even internal organs.
