There is a good general condition. After a mildly pronounced catarrhal stage with infection of the upper airways or gastrointestinal symptoms, exanthema forms. Lens sized, scarlitiniform, partly lichenoid and confluent, erythematous, discreetly scaling papules occur mostly axillanah, rarely also inguinal partly along the blaschko lines. The efflorescences are mostly unilaterally accentuated or exclusively unilaterally arranged. After 2 weeks, it spreads to the thoracic wall or leg as well as to the contralateral side. A regional lymphadenopathy must be expected.
Initially unilateral thoracoaxillary, in some cases also inguinal. Finally, spread to the contralateral side of the body. A symmetrical occurrence is also possible from the beginning in a few cases.
Discreet spongiosis, exocytosis, superficial perivascular lymphocytic dermatitis, otherwise unspecific.
Not possible.
