Although peritumoral lymphoid infiltrates are frequently interpreted as reactive, they may occasionally correspond to underlying or previously unrecognized lymphoproliferative disorders, with relevant clinical implications. We report three diagnostically challenging cases of epithelial skin cancers associated with unusual B\u2010cell lymphoproliferative disorders, including composite lymphomas and previously unreported associations. These cases highlight the broad spectrum of B\u2010cell lymphoproliferative conditions that may coexist with epithelial skin malignancies and underscore the importance of meticulous morphological assessment, comprehensive immunophenotypic characterization, and careful clinicopathological correlation. Awareness of this potential association is crucial to avoid misclassification of neoplastic lymphoid infiltrates as reactive processes and to ensure appropriate hematological work\u2010up and optimal patient management.<\/jats:p>","DOI":"10.1111\/cup.70178","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T00:37:07Z","timestamp":1784594227000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unusual
