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.
Early lesions may be colonized or infected by, Bacillus fusiformis (Vincent's organism), anaerobes and spirochaetes. Later, tropical ulcer may become infected with a variety of organisms, notably, staphylococci and/or streptococci. [4] The condition has been shown to be transmissible by inoculation of material from affected patients. [5]
Infection may vary in the depth of tissue to which it extends. Foot infections range from the most superficial, cellulitis, to deeper soft tissue necrotizing fasciitis, which may necessitate limb amputations or become life-threatening. [9] [10] [11] Infections may also extend to bone, termed osteomyelitis.
Often, gangrene is associated with underlying infection, thus the gangrenous tissue must be debrided to hinder the spread of the associated infection. The extent of surgical debridement needed depends on the extent of the gangrene and may be limited to the removal of a finger, toe, or ear, but in severe cases may involve a limb amputation .
Athlete's foot, known medically as tinea pedis, is a common skin infection of the feet caused by a fungus. [2] Signs and symptoms often include itching, scaling, cracking and redness. [3] In rare cases the skin may blister. [6] Athlete's foot fungus may infect any part of the foot, but most often grows between the toes. [3]
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. [1]
Pitted keratolysis (also known as keratolysis plantare sulcatum, [1] keratoma plantare sulcatum, [1] and ringed keratolysis [1]) is a bacterial skin infection of the foot. [2] The infection is characterized by craterlike pits on the sole of the feet and toes, particularly weight-bearing areas. The infection is caused by Kytococcus sedentarius.
Eumycetoma, also known as Madura foot, [1] [6] is a persistent fungal infection of the skin and the tissues just under the skin, affecting most commonly the feet, although it can occur in hands and other body parts. [5]
