Occurrence/EpidemiologyThis section has been translated automatically.
Very rare (less than 50 cases have been reported in the literature worldwide).
EtiopathogenesisThis section has been translated automatically.
Unknown. Triggering by a primary inflammatory event is discussed.
ManifestationThis section has been translated automatically.
Mainly middle-aged women (w:m=3:1).
LocalizationThis section has been translated automatically.
Mainly acra, legs, less often face.
Clinical featuresThis section has been translated automatically.
Solitary or multiple, occasionally also disseminated or generalized, 0.3-3.0 cm in size, pale reddish to livid, firm, flat, asymptomatic (mild itching is rarely described) papules with smooth surface, which tend to confluence.
HistologyThis section has been translated automatically.
- Beneath a slightly acanthotic epidermis there is a varying density, partly perivascular, partly diffuse infiltrate of lymphocytes, spindle-shaped cells and bizarre, large, multinucleated giant cells as well as numerous vessel incisions.
- Endothelial cells: positive staining with factor VIII related antigen, Ulex europaeus I lectin, CD31, CD 34.
- Giant cells (multinuclear histiocytes): positive staining with vimentin.
- Mononuclear histiocytes: positive staining with CD 68, lysozyme, alpha-1 antitrypsin; negative for S100 protein and CD1a.
Differential diagnosisThis section has been translated automatically.
Since the clinical picture is very heterogeneous (solitary and multiple, isolated or confluent papules, no symptoms) the diagnosis is based on the histological findings. As clinical differential diagnosis the following diseases are possible:
TherapyThis section has been translated automatically.
Lesions arranged in groups can be ablated with the laser (CO2 laser), individual lesions can be removed surgically, e.g. by punching. Recurrence rate apparently low (?).
