It is a form of psoriasis found in the armpits, groin, under the breasts and in other flexion creases such as those around the genitals and buttocks. It often results in redness and inflammation, with scaly, dead skin on the surface.
Fungal infections: Any condition caused by fungus.

Generalized pustular psoriasis: This is a rare form of psoriasis is also known as von Zumbusch psoriasis. It can be life-threatening especially in the elderly. It is characterized by the development of pustules in the flexural areas - the backs of the knees, the insides of the elbows, the armpits and the groin. These pustules continue to spread and soon they join to form lakes of pus. The pustules rupture easily and can become infected. This condition can be fatal if the patient gets dehydrated, or the infection spreads to the bloodstream. Generalized pustular psoriasis is often triggered by stopping topical or oral steroids.
Genital psoriasis: Psoriasis can occur in the genital area at the same time it occurs elsewhere on the body, or it can appear in the genital area only. People with genital psoriasis may have affected areas that range from small, red spots to large patches.

Infantile pustular psoriasis: Pustular psoriasis is a form of psoriasis characterized by pustules rather the skin bumps. There are various subtypes of the disorder: generalized, annular, palmoplantar or juvenile. Infantile pustular psoriasis tends to occur during infancy. The skin under and around the pustules is red. The blisters tend to occur in repeated waves with frequent spontaneous remissions.
Infection: Infections as a symptom.
Intertrigo: Skin inflammation from rubbing together of two skin areas
Juvenile pustular psoriasis: Pustular psoriasis is an uncommon form of psoriasis.People with pustular psoriasis have clearly defined, raised bumps on the skin that are filled with pus (pustules). The skin under and around these bumps is red. Large portions of your skin may redden.
Lichen planus: Skin rash
Lichen simplex chronicus: Lichen simplex chronicus refers to thickened itchy skin that results from persistently rubbing or scratching an area of skin.
Localized pustular psoriasis: Localized pustular psoriasis presents as two distinct conditions that must be considered separate from generalized psoriasis, and without systemic symptoms, these two distinct varieties being pustulosis palmaris et plantaris and acrodermatitis continua. Localized Pustular Psoriasis either occurs on the tips of the fingers (acropustulosis) or affects only the palms of hands, soles of feet (palmo-plantar pustulosis). It is very painful, and may keep you from any daily activity upon which you need your hands and feet, including walking and eating. Palmo-Plantar Pustulosis occurs in people between 20 and 60 years old, and may be triggered by infection and/or stress.
Mental retardation, X-linked - seizures - psoriasis: A rare syndrome characterized mainly by mental retardation, seizures and a skin disorder.
Mycosis fungoides: Mycosis fungoides is a rare form of T-cell lymphoma of the skin. The disease is typically slowly progressive and chronic.
Mycosis fungoides, familial: A rare form of lymphatic cancer (T-cell lymphoma) that primarily affects the skin and tends to occur with higher than normal frequency within a family. The skin is affected first, then the lymph nodes become inflamed and usually cancerous. The cancer can then spread to organs such as the liver, lungs and bone marrow. Survival depends on how early treatment starts. Patients diagnosed in the early stages can survive more than 12 years whereas once the cancer has spread to other organs, death usually occurs within three years.
Nail psoriasis: Persons with active psoriasis have psoriatic changes in fingernails and/or toenails. In some instances psoriasis may occur only in the nails and nowhere else on the body. Psoriatic changes in nails range from mild to severe, generally reflecting the extent of psoriatic involvement of the nail plate, nail matrix (tissue from which the nail grows), nail bed (tissue under the nail), and skin at the base of the nail. Damage to the nail bed by the pustular psoriasis can result in loss of the nail.
Neurodermatitis: Lichen simplex chronicus refers to thickened itchy skin that results from persistently rubbing or scratching an area of skin.
Neurosis: Variety of mental disorders with self-awareness
Nummular dermatitis: A skin disorder characterized by the development of round or oval skin lesions which itch and burn. In the initial stages, small red spots or blisters form and the grow and joint together to form a patch. The lesion eventually looks similar to a ringworm infection with a clear centre and a distinct border. The causes of some cases includes mercury fillings and allergy to rubber, nickel, formaldehyde or neomycin.

Onchyomycosis: A fungal infection of the nail. The toenails tend to be affected more than the fingernails.
Paget's Disease: Breast carcinoma involving nipple and areola.
Parapsoriasis: A group of skin condition characterized by red scaly skin which resemble psoriasis. The chronic, inflammatory skin lesions are relatively difficult to treat. The skin lesions may develop into cutaneous T-cell lymphoma.
Paronychia: Skin infection of a nail

Psoriasis arthropathica: Psoriatic arthritis is a chronic disease characterized by inflammation of the skin (psoriasis) and joints (arthritis). Psoriatic arthritis is said to be a seronegative spondyloarthropathy and therefore occurs more commonly in patients with tissue type HLA-B27 Syndrome in which psoriasis is associated with arthritis, often involving inflammation in terminal interphalangeal joints. A rheumatoid factor is not usually present in the sera of affected individuals.
