BACKGROUND: Unlike T-cell neoplasms, B-cell lymphoproliferative disorders have a limited clinical spectrum of skin involvement. Cutaneous B-cell neoplasms mimicking rosacea or rhinophyma are rare.
OBSERVATIONS: We described 12 patients with B-cell lymphoproliferative neoplasms presenting with a facial eruption clinically mimicking rosacea or rhinophyma. Eleven patients were women; ages ranged from 36 to 81 years. The clinical presentation included small papules on the nose and cheeks and around the eyes mimicking granulomatous rosacea; nodules on the nose, cheeks, chin, or forehead mimicking phymatous rosacea; or a combination of both. Three patients had preexisting erythematotelangiectatic rosacea and 1 had rhinophyma. Based on a clinicopathologic correlation and B-cell clonality analysis, the diagnosis was primary cutaneous follicular center B-cell lymphoma in 4 cases, primary cutaneous marginal zone lymphoma in 6, and skin involvement of chronic lymphocytic leukemia in 2. All patients had an indolent course as expected for their disease.
CONCLUSIONS: Cutaneous involvement of B-cell neoplasms may mimic granulomatous rosacea or rhinophyma. This unusual clinical presentation is more common in women and appears in the setting of preexisting rosacea or as a new eruption. Proliferative B-cell disorders should be added to the differential diagnosis of symmetric papular or papulonodular eruptions of the face.
