Two cases of primary cutaneous marginal zone B-cell lymphoma of the skin (SALT) are described in this article. Case 1 concerns a 57-year-old man who in 2006 removed four asymptomatic, reddish, nodular lesions on the right arm, the left arm, the forehead and the abdomen, respectively. A biopsy of all lesions showed similar changes and resulted in a cutaneous marginal B-cell lymphoma. During the follow-up no lesion recurred. Case 2 concerns a 53-year-old man who presented four reddish lesions on the sacral, the axillary, the hemithorax and the lumbar left sites which received the same diagnosis. This phenotype of the lymphoma is considered as part of MALT lymphomas. These lymphomas are characterized by low grade indolent course, with persistent and recurrent nodular lesions.
