BACKGROUND: Dermatopathic lymphadenitis is a rare benign lymphatic hyperplasia commonly associated with exfoliative or eczematoid dermatitis. Of interest, this condition can be confused with lymphatic metastasis in adults.

CASE REPORT: In this report, we describe the case of a 56-year-old woman diagnosed with left breast invasive ductal carcinoma in remission, who presented with dermatopathic lymphadenitis mimicking breast cancer recurrence.

CONCLUSIONS: Dermatopathic lymphadenitis is a benign entity that needs to be considered in the differential diagnosis of lymphadenopathy. Pursuing extensive workup in asymptomatic patients with a similar presentation and initial negative tests for malignancy recurrence is not recommended.
