Summary

The annular erythemas are a group of cutaneous eruptions characterized by their morphological pattern. They are dermatoses with annular, arcuate, circinate, polycyclic or serpiginous configurations which may spread peripherally or remain fixed.

In the literature, the annular erythemas have been classified under such headings as gyrate, figurate or reactive erythemas. Several of the annular erythemas have been associated with an underlying condition, which suggests that they may represent a hypersensitivity reaction. Differentiating between the annular erythemas can be difficult because there may be considerable clinical and histological overlap between the individual variants. Subtle variations in morphological presentation, age of patient, duration of eruption and associated symptoms may aid in making a diagnosis.
