The primary cutaneous marginal zone B cell lymphoma is a small B cell lymphoma, including cells of the marginal zone, lymphoplasmacytic cells, and plasma cells. Clinically it manifests as erythematous or erythematous-violaceous papules, plaques, or nodules, single or multiple, most often located to the extremities. Its course is usually indolent, with a survival at 5 years of approximately 97 percent. The tumor exhibits a tendency towards local recurrence, but spread to locations outside the skin is extremely rare. We present a case report of a man, 80 years of age, with a primary cutaneous marginal B cell lymphoma of the chin, an atypical location.
