Folliculitis is the infection and inflammation of one or more hair follicles. The condition may occur anywhere on the skin except the palms of the hands and soles of the feet. The rash may appear as pimples that come to white tips on the face, chest, back, arms, legs, buttocks, or head.
Papular mucinosis is a rare skin disease. Localized and disseminated cases are called papular mucinosis or lichen myxedematosus while generalized, confluent papular forms with sclerosis are called scleromyxedema. Frequently, all three forms are regarded as papular mucinosis. However, some authors restrict it to only mild cases. Another form, acral persistent papular mucinosis is regarded as a separate entity.
Prurigo gestationis is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.
Angiolymphoid hyperplasia with eosinophilia usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck, especially about the ears and on the scalp.
Angioma serpiginosum is characterized by minute, copper-colored to bright red angiomatous puncta that have a tendency to become papular.
Alopecia mucinosa is a skin disorder that generally presents, but not exclusively, as erythematous plaques or flat patches without hair primarily on the scalp, neck and face. This can also be present on the body as a follicular mucinosis and may represent a systemic disease.
Lichen myxedematosus is a group of cutaneous disorders considered mucinoses. Conditions included in this group are:
Localized lichen myxedematosus is a group of skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides, a disease for which there is no treatment.
Discrete papular lichen myxedematosus is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides characterized by the occurrence of waxy, flesh-colored papules.
Acral persistent papular mucinosis is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides, characterized by bilaterally symmetrical, flesh-colored papules localized to the hands and wrists.
Self-healing papular mucinosis is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides, and may present in adult and juvenile forms. The juvenile variant is also called self-healing juvenile cutaneous mucinosis.
Reticular erythematous mucinosis (REM) is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides. It is a disease that tends to affect women in the third and fourth decades of life.
Cutaneous focal mucinosis is a skin condition characterized by a solitary nodule or papule.
Papular xanthoma is a cutaneous condition that is a rare form of non-X histiocytosis.
Urticaria-like follicular mucinosis is a rare cutaneous disorder that occurs primarily in middle-aged men.
Stiff skin syndrome is a cutaneous condition characterized by ‘rock hard’ induration, thickening of the skin and subcutaneous tissues, limited joint mobility, and mild hypertrichosis in infancy or early childhood. Immunologic abnormalities or vascular hyperactivity are not present in patients.
Nodular lichen myxedematosus is a cutaneous condition characterized by multiple nodules on the limbs and trunk, with a mild or absent papular component.
Cutaneous lupus mucinosis is a cutaneous condition characterized by lesions that present as asymptomatic skin-colored, at times reddish, 0.5–2 cm papules and nodules.
Eccrine mucinosis is a cutaneous condition characterized by mucinosis, and described in HIV-infected patients.
Perifollicular mucinosis is a cutaneous condition characterized by mucinosis, and described in HIV-infected patients.
