Recurrent Erythema Nodosum Associated With Finger Millet–Blended Injera: A Case Report on a Potential Dietary Trigger

Abstract

This case report presents a recurrent episode of erythema nodosum (EN) potentially associated with the consumption of finger millet-blended injera. The patient developed EN manifestations within 1 week of initiating intake of injera prepared from teff and finger millet, with symptoms persisting for 6 months. Following dietary elimination of finger millet, complete clinical resolution was observed, and no recurrence was documented during an 8-month follow-up. However, causality cannot be confirmed due to the lack of allergy testing, dietary rechallenge, and histopathological verification. This case highlights the value of detailed dietary assessment, including less commonly consumed cereals, in the diagnostic evaluation and management of recurrent or idiopathic EN.
