Presentamos el caso de un paciente masculino diagnosticado y tratado previamente por linfocitoma cutis, quien acudió por la aparición de nuevas dermatosis ipsilaterales en las regiones temporal y parietal, con datos dermatoscópicos sugestivos de LCPCB. El diagnóstico histopatológico fue realizado por un dermatopatólogo especializado en linfomas cutáneos y posteriormente confirmado con estudios de extensión. El tratamiento consistió en escisión quirúrgica más radioterapia. Actualmente, el paciente se encuentra en remisión. La comunicación de neoplasias cutáneas raras en población mexicana contribuye a su reconocimiento y a la difusión de estrategias de abordaje y manejo.]]></p></abstract>

We present the case of a male patient previously diagnosed and treated for cutaneous lymphocytoma who presented with the development of new ipsilateral dermatoses in the temporal and parietal regions, with dermoscopic findings suggestive of PCBCL. The histopathological diagnosis was established by a dermatopathologist specialized in cutaneous lymphomas and subsequently confirmed with staging studies. Treatment consisted of surgical excision followed by radiotherapy. The patient is currently in remission. Reporting rare cutaneous neoplasms in the Mexican population contributes to their recognition and to the dissemination of diagnostic and management strategies.]]></p></abstract>
