« Malignant » Rosacea as a sign of systemic marginal zone lymphoma

Abstract

Rosacea is a common facial dermatosis for which differential diagnoses have to be considered in the case of atypical features or treatment failure. We report 3 cases of systemic marginal zone lymphomas (MZL), with skin involvement simulating rosacea. A 76-year-old man presented a rhinophyma for one year (Fig 1).
