Tuberculosis verrucosa cutis is a rash of small, red papular nodules in the skin that may appear 2–4 weeks after inoculation by Mycobacterium tuberculosis in a previously infected and immunocompetent individual.
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.
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.
Papular mucinosis of infancy is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides, characterized by skin-colored or translucent papules.
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.
Non-X histiocytoses are a clinically well-defined group of cutaneous syndromes characterized by infiltrates of monocytes/macrophages, as opposed to X-type histiocytoses in which the infiltrates contain Langerhans cells. Conditions included in this group are:
Papular xanthoma is a cutaneous condition that is a rare form of non-X histiocytosis.
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.
Sarcoidosis involves the skin in about 25% of patients. The most common lesions are erythema nodosum, plaques, maculopapular eruptions, subcutaneous nodules, and lupus pernio. Treatment is not required, since the lesions usually resolve spontaneously in two to four weeks. Although it may be disfiguring, cutaneous sarcoidosis rarely causes major problems.
