ERYTHEMA GYRATUM REPENS
By Gary M. White, MD
Erythema gyratum repens (EGR) is a rare often paraneoplastic syndrome most commonly associated with lung, esophageal, and breast carcinoma.
- In a review of 112 cases, 58 (70%) were associated with an underlying neoplasm, 25 (30%) were non-paraneoplastic and 29 were considered as different dermatoses mimicking EGR in their clinical presentation 'EGR-like' eruption) [JEADV 2014;28:112-5]
Gyrate erythematous and scaly lesions are widespread. The appearance can be akin to erythema annular centrifugum. The annular, wavy, red, scaly lines are sometimes said to fit together like "grains of wood".
If paraneoplastic, removing the malignancy clears the rash.
This case of EAC was dense enough in some areas to resemble EGR.
