Epithelial sheath neuroma (ESN) is a rare entity, histologically showing enlarged nerves in the superficial dermis surrounded by cytologically bland keratinocytes, classically presenting clinically as an erythematous papule or nodule on the back of middle‐aged to elderly individuals. Clear‐cut recommendations for treatment are not available, with many reports citing biopsy alone or simple excision as curative. We report a case of biopsy‐proven ESN presenting as a significantly painful nodule in an elderly woman. Surgical excision was performed for symptom control and the residual ESN was found to extend deep into the subcutis.
