Is eccentric annular erythema cancer precursor?

Eccentric annular erythema generally refers to eccentric annular erythema, which may be a precursor to cancer, but not necessarily.

Eccentric annular erythema may be a precursor to cancer or malignant tumor. Eccentric annular erythema belongs to the category of skin disease clinically. It is good to occur on the limbs and trunk of the human body. It is manifested as annular erythema and eccentric expansion. Although there is no definite conclusion on the etiology of erythema annularis dissociata, many research data show that it is related to allergy, mosquito bite, infection, family inheritance and other factors. Very few cases are related to malignant tumor, i.e. cancer, and the specific pathogenesis is still unclear.
