Malum perforans is a long-lasting, usually painless ulcer that penetrates deep into or through the skin, usually on the sole of the foot (in which case it may be called malum perforans pedis). It is often a complication in diabetes mellitus and other conditions affecting the nerves.
Diabetic foot ulcer is a breakdown of the skin and sometimes deeper tissues of the foot that leads to sore formation. It is thought to occur due to abnormal pressure or mechanical stress chronically applied to the foot, usually with concomitant predisposing conditions such as peripheral sensory neuropathy, peripheral motor neuropathy, autonomic neuropathy or peripheral arterial disease.

Calluses (plantar in right foot and medial in left foot) A callus (pl.: calluses) is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin.
Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
Pressure wounds are often the result of local ischemia from the increased pressure. Increased pressure also plays a roles in many diabetic foot ulcerations as changes due to the disease causes the foot to have limited joint mobility and creates pressure points on the bottom of the foot.
Diabetic foot infection is any infection of the foot in a diabetic person. [2] The most frequent cause of hospitalization for diabetic patients is due to foot infections. [ 3 ] Symptoms may include pus from a wound, redness, swelling, pain, warmth, tachycardia , or tachypnea. [ 4 ]
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. [3]
A diabetic foot disease is any condition that results directly from peripheral artery disease (PAD) or sensory neuropathy affecting the feet of people living with diabetes. Diabetic foot conditions can be acute or chronic complications of diabetes. [1] Presence of several characteristic diabetic foot pathologies such as infection, diabetic foot ...
