Pityriasiform deramtitis suggestive of Superficial erythema annulare centrifugum. Histologically, pityraisis rosea shows overlapping features with sperifical EAC, but in this case the clinical description is more likely of EAC.

if clinical information is annular lesion then epidermal focal parakeratosis with superficial dermal perivascular lymphocytes and a few eosinophils. since not responding to fungal treatment to rule out figurative erythema -EAC but CPC required

Histologically Pytiriasis rosea of Gilbert, because of superficial perivascular infiltrate. Question: could a mother plaque become confluent with other ones around?
