Erythema elevatum diutinum and hypothyroidism: coincidence or causal relationship?

Atypical Palmar Involvement with Erythema Elevatum Diutinum as a Sole Manifestation: A Report of Two Cases

Erythema elevated diutinum (EED) is a rare distinctive form of cutaneous leukocytoclastic vasculitis. EED typically presents with asymptomatic symmetrical erythematous-brown papules, nodules or plaques which favor the extensor aspect of extremities while distinctly sparing the palms. We report two cases of EED with a rare presentation limited to the palms.

Erythema elevatum et diutinum as a systemic disease

Erythema elevatum et diutinum (EED) is a rare, chronic dermatosis. It has been associated with extracutaneous findings, including arthralgias, scleritis, panuveitis, peripheral ulcerative keratitis, oral and penile ulcers, and neuropathy. Additionally, EED is connected with various systemic diseases, including HIV, IgA paraproteinemia, myelomas, neutrophilic dermatoses, and inflammatory bowel diseases. The presence of such extracutaneous manifestations in EED patients suggests that EED may be a multiorgan entity. Extracutaneous manifestations in EED may involve deposition of circulating immune complexes; thus, patients with EED should be evaluated for systemic manifestations to ensure targeted management.

Erythema elevatum diutinum involving palms and soles: a case report and literature review

Erythema elevatum diutinum (EED) is a rare chronic inflammatory dermatosis and a part of the spectrum of cutaneous leukocytoclasticvasculitis. The most common site of involvement is extensor surface of the extremities, with a predilection for the skin overlying joints, particularly hands, feet, elbows and knees, as well as buttocks and Achilles tendons. Here we report a case of EED with atypical presentation involving palms and soles. The patient showed dramatic response to the treatment with prednisolone combined with Tripterygium wilfordii glycoside (TWP). The lesions improved significantly after three months of therapy. We will also review the atypical cases of EED that were previously published in English literature.
