摘要

A 6-year-old boy presented with recurrent pruritic scalylesions all over trunk for last 2 years. These lesionsappeared spontaneously and resolved in 4-8 weeks withoutany sequale. Rest of the history was non-contributory andno other family member was having similar lesions. Onexamination, multiple, annular erythematous lesions withtrailing scale at the inner border were present on trunk (Fig.1). Few annular lesions were found on tongue too. Onenquiry, tongue lesions used to appear and disappearsimultaneously with trunk lesions. Palm, sole, nail, scalpand other mucosa were unremarkable. Routineinvestigations and KOH mount did not reveal anyabnormality. Clinically, the child was diagnosed asErythema annulare centrifugum (EAC). Histopathologicalfindings were consistent with the diagnosis. Involvement oftongue is very rare. The incidence of disease peaks in thefifth decade.
