AMP case report: Use of molecular techniques to solve a challenging case of primary cutaneous marginal zone lymphoma
April 2024—Primary cutaneous marginal zone lymphoma (PCMZL) is a newly recognized, distinctive subtype of non-Hodgkin’s lymphoma. This low-grade lymphoma predominantly presents as papules or nodules within the skin of middle-aged adults. Formerly grouped under the extranodal marginal zone lymphoma (EMZL) category, the World Health Organization’s fifth edition classification of hematolymphoid tumors now recognizes PCMZL as a distinct entity.
