👉 Haplothorax is a term used in medicine that describes a condition where a patient's body produces too much collagen, which can lead to skin and joint problems. This condition may be caused by a genetic defect or an injury to the connective tissue in the body. Haplothorax can affect multiple areas of the body, including the face, neck, and hands. It is often associated with conditions such as rheumatoid arthritis, psoriasis, and lupus.
