Lesions on the 1st and 2nd day of onset. On the 1st day: A – red, oedematous helix, B – red, oedematous helix and antihelix with few purpuric dots. On the 2nd day; C – ecchymotic purpura of the left cheek with a rosette-shaped border, D – targetoid, ecchymotic eruption of the right cheek. On the 3rd day: E – ecchymotic cockade purpura and oedema which extend to the mouth angle and angle of the jaw of the left face, F – the oedematous erythematous lesion extends to cover most of the helix and antihelix of the left auricle. On the 4th day: G – the targetoid, ecchymotic lesions confluent and extend to cover most of the right face, H – ecchymotic lesion extends more to cover most of the right face. On the 5th (I), 6th (J), and 7th (K) day of onset, lesions start to resolve by changing to brownish-red colour in figure. L – Lesions resolve leaving central crust on the 8th day of onset

Histology shows orthokeratosis, spongiosis of the epidermis, lymphocytes extravasation is seen in the epidermis, dilated upper-dermis blood vessels with erythrocyte extravasation in all dermis levels (haematoxylin and eosin staining; original magnification 200×). (B) Deep perivascular infiltrate composed mostly of neutrophils with abundant nuclear dust; the inflammatory cells extend to the fat tissue; adnexal structures are unaffected. However, there is a mild inflammatory cell (haematoxylin and eosin staining; original magnification 200×). (C) higher magnification of (A) shows fibrinoid necrosis, neutrophilic nuclear dust (haematoxylin and eosin staining; original magnification 400×)
