Unilateral laterothoracic exanthema, ULE, asymmetrical exanthema, asymmetrical periflexural exanthema of childhood, APEC.
Self-limiting, 4-6 weeks lasting, probably infectious allergic skin disease of childhood.
The triggering agent has not yet been described.
There is a good general condition. After a mild catarrhal stage with upper respiratory tract infection or gastrointestinal symptoms, exanthema develops. Lens-sized, scarlitiniform, partly lichenoid and confluent, erythematous, discretely scaling papules occur mostly axillary, rarely also inguinal partly along the Blaschko lines. The efflorescences are mostly unilaterally accentuated or exclusively unilaterally arranged. After 2 weeks, the efflorescence spreads to the thoracic wall or leg and to the contralateral side. Regional lymphadenopathy must be expected.
Initially unilateral thoracoaxillary, in some cases also inguinal. Eventually spreading to the contralateral half of the body. Symmetrical occurrence is also possible from the beginning in a few cases.
Decent spongiosis, exocytosis, superficial perivascular lymphocytic dermatitis, otherwise nonspecific.
