Overview
Historical Perspective
- Erythema gyratum repens was first described by Dr. John A Gammel, the dermatologist, who was trained to link bizarre or recalcitrant dermatoses to internal diseases, In 1952, in a 55-year-old patient who had been complaining of pruritic scaly skin eruption and diagnosed nine months later with poorly differentiated adenocarcinoma of the breast with metastasis to axillary lymph nodes [1] [2]
- In 1950, Dr. Gammel presented his case before the Cleveland Dermatological Society as Erythema gyratum migrans then he changed the term to erythema gyratum repens because the eruption does not "migrate" from one place to another but "crawls" constantly in the areas involved, like ants on an anthill [1]
- The association between cutaneous manifestations and systemic malignancies was first studied in 1925 by Rothman, the Hungarian investigative dermatologist, who wrote a comprehensive review on this subject and since then, cases were added to proof for the relationship between internal neoplasm and some skin lesions [3] [4]
- In 1973, 45 year old man was diagnosed with erythema gyratum repens associated with metastatic, undifferentiated adenocarcinoma which was removed following a right- sided craniotomy. The patient was misdiagnosed with erythema perstans and the malignancy was discovered after 8 months of the skin manifestations. [5]
- Up to 1992, there were only 49 cases in the literature, 41 of which (84%) were associated with a neoplasm [6]
- Between 1990 and 2010, a literature review was done by collecting data from the medical records of patients form dermatology department in University of Genoa and from databases as pubmed and medline, to conclude that erythema gyratum repens is no longer considered as an obligate paraneoplastic syndrome. More than expected cases of EGR were found with no neoplasm association [7]
Classification
- Erythema gyratum repens has no established system for the classification. However, we can classify erythema gyratum repens based on its association with systemic malignancy as:
- Paraneoplastic EGR
- Erythema gyratum repens is associated with internal malignancy in 82% of cases [7]
- Non-paraneoplastic EGR could be:
- Idiopathic EGR
- EGR-like eruptions (different dermatologic lesions that mimic EGR)
- EGR with concomittant skin disease as:
- pityriasis rubra pilaris, psoriasis, ichthyosis, CREST, rheumatoid arthritis, tuberculosis, bullous pemphigoid, linear IgA disease, and hypereosinophilic syndrome
- Drug-induced EGR examples are:
- Azathioprine with type I autoimmune hepatitis
- Interferon given for hepatitis C virus–related chronic hepatitis
- Paraneoplastic EGR

Pathophysiology
- The pathogenesis of erythema gyratum repens is unclear [8] [9]
- Many immunologic theories have been implicated in its pathogenesis
- The immunologic mechanism theory is evidenced by the observed immunofluorescence patterns of IgG, C3, and C4 at the basement membrane: [9]
- Theory 1: the tumor induces antibodies that cross-react with the basement membrane of skin
- Theory 2: the tumor produces polypeptides that bind skin antigens and render them immunogenic
- Theory 3: deposition of tumor antigen-antibody complexes onto the basement membrane causes reactive dermatitis seen in EGR
- The gross appearance of the unique eruptions are:
- Wavy erythematous concentric bands that can be figurate, gyrate, or annular
- The bands are arranged in parallel rings and lined by a fine trailing edge of scales, a pattern often described as “wood grained”
- The distinctive wood grain appearance of the eruption is pathognomonic
- The rash typically involves large areas of the body but tends to spare the face, hands, and feet and it can expand as fast as 1 cm a day.
- Bullae can also form from within the areas of erythema
- The microscopic histologic features of erythema gratum repens are not characteristics but the following are the biopsy specimen findings that are compatible with the diagnosis: [1][5] [10]
- The epidermis has thin atrophic patches with areas of acanthosis, focal parakeratotic horny layers, and spongiosis
- The dermis contains a moderate perivascular mononuclear, lymphocytic, and histiocytic infiltrate in the superficial plexus as well as mild focal spongiosis and parakeratosis
- Eosinophils and melanophages have also been reported in the dermal infiltrate
- Diffuse to moderate edema of the connective tissue can be seen
Causes
- The exact cause of EGR is unknown
- Various immunologic mechanisms suggest that EGR etiology is stemmed from an immunologic reaction.
- The association between erythema gyratum repens and systemic malignancy is evidenced by the disappearance of the pruritic eruptions after the treatment of the underlying neoplasm.
- The association doesn't necessarily mean causation.
Differentiating Erythema Gyratum Repens from Other Diseases
- EGR has a narrow differential diagnosis. It has to be differentiated from Reactive gyrate erythematous eruptions, such as:
- Reactive (figurate or gyrate) erythemas that are associated with malignancy include:
- Erythema annulare centrifugum (EAC)
- Necrolytic migratory erythema (NME)
- Reactive (figurate or gyrate) erythemas that are not associated with malignancy include:
- Erythema marginatum rheumaticum
- Erythema chronicum migrans
- Familial annular erythema
- The carrier state of chronic granulomatous disease
- Subacute cutaneous lupus erythematosus
- Neonatal lupus erythematosus
- Reactive (figurate or gyrate) erythemas that are associated with malignancy include:
