Causes of IndurationSkin induration often develops due to conditions triggering inflammatory processes and infiltration of cancer cells into body tissues. Some common causes of induration are listed below.Skin InfectionsVarious types of skin infections can lead to induration of the skin. These include:Infections leading to abscesses (pus-filled bumps or pockets under the skin)Bacterial infections of the soft tissuesWound infectionsInsect bite infectionsChronic ConditionsCertain conditions that trigger inflammatory processes can cause induration of the skin. A few common conditions are:Scleroderma: This autoimmune condition causes skin inflammation and thickening. Improper immune system functioning leads to excessive collagen production, which ultimately causes skin hardening. Collagen is a naturally occurring protein in your body found in connective tissues, including skin and muscles.Diabetes mellitus: Diabetes can cause skin hardening, especially in the peripheral parts of the body like arms, feet, nails, hands, or legs.Panniculitis: This is a group of conditions characterized by inflammation of the body's subcutaneous fat tissue (fat tissue located right under your skin). It can cause induration of skin along with formation of nodules and plaques.Lichen sclerosus: This chronic (long-term) inflammatory condition forms white patchy areas that often become indurated.Venous stasis dermatitis: This condition causes poor lower leg circulation. It's also called stasis dermatitis, venous eczema, and gravitational dermatitis.Cancer Cell InfiltrationThe migration of cancer cells, also called cutaneous metastatic disease, from the primary tumor to other body tissues can cause skin induration. This most often occurs in cases of lung or breast cancer. Skin cancer can also cause skin induration.When To See a Healthcare ProviderYou may want to see a healthcare provider if your skin starts turning thick or bumpy for no known reason.
