Figure 10.2. Giberta pink dandruff – typical spreading pale pink spots on the skin of the trunk.
Clinical: A characteristic location is the torso along the clefts and close parts of the limbs; at the beginning of the disease, the so-called mother lamina, i.e. a large spot with a diameter of a few centimeters, with clear peeling around the perimeter, after a few days (6-10) numerous, pale pink spots of oval or round shape are sown, with delicate exfoliation of the surface, these lesions are much smaller than the mother lamina ; The symptoms are small – sometimes there is a slight itching, the general condition of the patients is good, the changes disappear spontaneously after 4-8 weeks, do not recur, the disease may have a different course in people of Spanish and black origin. Then, eruptions appear on the face, neck and distal parts of the limbs (the so-called inverted pink dandruff). They are usually smaller, lumpy, very itchy and resolve with significant post-inflammatory hypopigmentation, in smaller children (under 10 years of age), there may be lesions with the same distribution as in the inverted form, but more edema. Other, less common, varieties are hemorrhagic and vesicular.
Hist .: Acanthosis, intracellular and intercellular edema, leading lymphocytes and leukocytes from inflammatory infiltrates in the skin are present in the epidermis. Usually there is a slight parakeratosis. In the upper layers of the dermis, there are dilated blood vessels surrounded by infiltrates of lymphocytes, histiocytes and leukocytes.
DR: Tinea, psoriasis, seborrheic eczema, maculopapular exanthema in secondary syphilis, drug reactions (e.g. gold salts).
But: In most cases, it does not require treatment. In general, local treatment is sufficient – mash with 1% menthol, possibly medium-strength steroid preparations, in case of severe itching – antihistamines.
Year: The disease lasts 4-8 weeks and usually resolves on its own. In rare cases, the lesions may persist for up to 3-4 months. Resolution of changes may be accompanied by hyperpigmentation; relapses are very rare.
