The pathogenesis of erythema annulare centrifugum (EAC) is unknown, but it is probably due to a hypersensitivity reaction to a variety of agents, including drugs, arthropod bites, infections (bacterial, mycobacterial, viral, fungal, filarial), ingestion (blue cheese Penicillium), and malignancy.
Pathophysiology. Bloom syndrome (congenital telangiectatic erythema) is caused by a mutation in both alleles of the gene designated BLM, traced to band 15q26.1. BLM encodes 1417 amino acids that code for a protein in the nuclear matrix of growing cells, which is a member of the RecQ family of helicases.hotosensitivity in Bloom syndrome patients is a result of increased susceptibility to 313-nm light, approaching the ultraviolet (UV)âA range. The minimal erythema dose threshold for both UV-A and UV-B are reduced.
