Primary cutaneous marginal zone lymphomas (PCMZL) share histological and clinical characteristics with mucosa-associated lymphoid tissue (MALT) lymphomas suggesting a common pathogenesis. A number of recurrent structural and numerical chromosomal aberrations have been described in MALT lymphoma, but their incidence in PCMZL is largely unknown, as is their relation with clinical and pathological data. In this study, the incidence of t(11;18)(q21;q21), t(1;14)(p22;q32), two different t(14;18)(q32;q21), involving either IGH/MALT1 or IGH/BCL2, and numerical aberrations of chromosomes 3, 7, 12 and 18 were analysed in 12 patients with PCMZL, with follow-up of up to 10 years. Nuclei were isolated from paraffin wax sections for dual-colour interphase fluorescence in situ hybridization (FISH) using various probe sets either flanking or spanning the involved genes. T(14;18)(q32;q21), with breakpoints in IGH and MALT1, was found in three cases. All three had partly monocytoid histological appearances and lacked blastic transformation. An additional trisomy of chromosome 3 was detected in one of these cases. Trisomy 18 was present in two lymphomas without monocytoid morphology. No definite correlation was seen with any clinical feature, including Borrelia serology. Neither t(11;18)(q21;q21), nor t(1;14)(p22;q32) or any other translocation involving IGH, BCL10, MALT1, BCL2 and API2, amplification or deletion of chromosomal region 11q21, 18q21, 1p22, and 14q32 was detected. These results indicate that a subgroup of PCMZL with partly monocytoid morphology is genetically related to MZL at other extranodal sites.
