Erythema elevatum diutinum with lower limb neuropathy: A rare presentation
Abstract
Nodular lesions can be seen in a wide range of conditions such as infections, granulomatous conditions, neutrophilic disorders, vasculitis, benign tumours and malignant conditions. These numerous aetiologies behind the occurrence of nodular lesions signify the importance of thorough work-up of the patient to diagnose the underlying reason behind the clinical condition. Erythema elevatum diutinum (EED) is a rare vasculitis with variable clinical presentation, the diagnosis of which can be challenging. Extracutaneous signs such as arthralgias, oral and penile ulcers, involvement of the eye and neuropathy have all been linked to it. Various systemic illnesses, infectious diseases, autoimmune diseases, haematological abnormalities and plasma cell dyscrasias are also associated with EED. Such extracutaneous signs in EED patients indicate that the condition may involve several organ systems. Patients with EED should be assessed for systemic manifestations to ensure focused care, since extracutaneous forms of EED may comprise deposition of circulating immune complexes.
