- Most common underlying neoplasms are from lung, breast, or esophagus
- Some cases of erythema gyratum rapens–like eruptions are associated with infection (tuberculosis), connective tissue disease (lupus, Sjogren syndrome), or are idiopathic, but most cases are associated with a solid organ malignancy.
