HistoryThis section has been translated automatically.
Müller and Winkelmann, 1963
DefinitionThis section has been translated automatically.
Very rare, spontaneously healing (benign) non-Langerhans cell histiocytosis
EtiopathogenesisThis section has been translated automatically.
Unknown; self-limited benign histiocytic systemic disease.
ManifestationThis section has been translated automatically.
Mainly occurring in adults, very rarely in children. So far, less than 20 cases have been described in the literature.
Efflorescence(s)This section has been translated automatically.
Disseminated, brown smooth, non-confluent, asymptomatic papules.
LocalizationThis section has been translated automatically.
Face, trunk, proximal extremities.
Clinical featuresThis section has been translated automatically.
Progression in phases (phases of activity lasting from a few weeks to months). Generalised clinical picture with disseminated, skin-coloured or reddish-brown, smooth, mostly asymptomatic (rarely slight itching), 0.3-1.0 cm large papules which do not tend to confluence and appear on unmodified skin. At full manifestation usually 50 to 1000 efflorescences occur. Mucous membranes, palmae and plantae are almost always free. Recess of the large bends.
HistologyThis section has been translated automatically.
Regularly stratified surface epithelium with orthokeratotic keratinization. In the upper and middle dermis, there is a dense patchy infiltrate of slightly vacuolated predominantly mononuclear macrophages (CD68+, only very occasionally S 100+, CD1a-) and lymphocytes; no foam or giant cells. Infiltrate-free border zone below the epidermis.
Electron microscopy: Large numbers of electron-dense, regularly structured "laminated bodies" are seen in the tumor cells, but no Langerhans granules.
Usually no presence of foam cells or giant cells.
Immunohistology: Notice. Histiocytes are positive for Stabilin-1(scavenger receptor protein) and CD68 markers, negative for CD1a and S100 markers(S100 only very occasionally positive).
Differential diagnosisThis section has been translated automatically.
Other non-Langerhans cell histiocytoses, in particular multicentric reticulohistiocytosis and multinodular, storing, partly giant cell reticulohistiocytosis Differentiation from congenital self-healing reticulohistiocytosis (Birbeck granules negative; S100 positive; CD1a negative) is possible by ultrastructural means and immunohistology.
Complication(s)This section has been translated automatically.
TherapyThis section has been translated automatically.
Waiting, because of benign course with spontaneous remissions.
Radiation therapyThis section has been translated automatically.
Individual case reports on positive effects of PUVA therapy are available (systemic PUVA with meladinine 0.5 mg/kg bw; GD 1.25 J/cm2).
Progression/forecastThis section has been translated automatically.
Later development of acute leukaemia is possible, therefore regular checks of the differential blood count.
