Even i thought of IgE but would it not be deposited on mast cells rather than in the microvasculature.

IgM Erythema multiforme lesions like that on periphery its red and in centr pale in color.

Erythema multiforme is a skin condition of unknown cause, possibly mediated by deposition of immune complex (mostly IgM) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure. It is a common disorder, with peak incidence in the second and third decades of life.

he mild form usually presents with mildly itchy (Itching can be severe), pink-red blotches, symmetrically arranged and starting on the extremities. It often takes on the classical "target lesion" appearance,[2] with a pink-red ring around a pale center. Resolution within 710 days is the norm.
