Multiple annular erythematous lesions with trailing scale.

A 6-year-old boy presented with recurrent pruritic scaly lesions all over trunk for last 2 years. These lesions appeared spontaneously and resolved in 4-8 weeks without any sequale. Rest of the history was non-contributory and no other family member was having similar lesions. On examination, multiple, annular erythematous lesions with trailing scale at the inner border were present on trunk (Fig. 1). Few annular lesions were found on tongue too. On enquiry, tongue lesions used to appear and disappear simultaneously with trunk lesions. Palm, sole, nail, scalp and other mucosa were unremarkable. Routine investigations and KOH mount did not reveal any abnormality. Clinically, the child was diagnosed as Erythema annulare centrifugum (EAC). Histopathological findings were consistent with the diagnosis. Involvement of tongue is very rare. The incidence of disease peaks in the fifth decade.
