Malum perforans

Malum perforans (pronunciation: /ˈmæləm pɜːrˈfɔːrænz/), also known as a trophic ulcer or neurotrophic ulcer, is a long-lasting, usually painless ulcer that penetrates deep into or through the skin, usually on the sole of the foot.

Etymology

The term "malum perforans" is derived from the Latin words "malum" meaning "evil" and "perforans" meaning "piercing". It was first used in medical literature in the late 19th century.

Causes

Malum perforans is typically caused by decreased sensation in the foot, often due to diabetes or leprosy. Other causes can include syphilis, spinal cord injury, and peripheral neuropathy.

Symptoms

The primary symptom of malum perforans is a painless ulcer on the foot. The ulcer can be deep, often penetrating to the bone. Other symptoms can include swelling, redness, and a foul-smelling discharge.

Treatment

Treatment for malum perforans typically involves managing the underlying condition causing the decreased sensation in the foot. This can include controlling blood sugar levels in patients with diabetes or treating the infection in patients with leprosy. In some cases, surgery may be required to remove dead tissue or to correct deformities.
