RESUMEN
Se evaluaron las características clínicas, histológicas y la evolución de una cohorte de pacientes con linfomas de la órbita y anexos oculares. Entre 1995 y 2008 se estudiaron 25 casos de linfomas de la órbita y anexos oculares en un centro oncológico de referencia. En cada caso se analizó el inmunofenotipo usando un panel de anticuerpos monoclonales (CD45, CD20, CD3, CD5, CD23, BCL2, BCL6, BCL10, Ki67, CD30, CD15, BCL1, Kappa, Lambda, CD138). Las lesiones fueron evaluadas utilizando el sistema de clasificación de linfomas (OMS, 2008). Se analizaron 23 linfomas primarios y dos secundarios. Los subtipos histológicos fueron 16 linfomas B de la zona marginal asociados a las mucosas (MALT), cuatro linfomas difusos de células grandes B, dos linfomas foliculares y un paciente con linfoma Hodgkin. De los 25 casos estudiados, 22 presentaron estadios localizados. El linfoma MALT fue el subtipo más frecuente. En este estudio se observó enfermedad localizada en la mayoría de los casos y con baja progresión a distancia.
ABSTRACT
Clinical, histological features and outcome of a cohort of patients with orbital and adnexal lymphoproliferative tumors were evaluated. Twenty-five cases in an oncologic referral center from 1995 to 2008, were included in the study. Each case had detailed immunophenotypic analysis using a panel of monoclonal antibodies (CD45, CD20, CD3, CD5, CD23, BCL2, BCL6, BCL10, Ki67, CD30, CD15, BCL1, Kappa, Lambda, CD138). Lesions were classified by using WHO (2008) lymphomas classification. Twenty-three patients were found to have primary and two secondary lymphomas. Histological subtypes were 16 patients with marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma, four diffuse large B cell lymphomas, two mantle cell lymphomas, two follicular lymphomas, and one Hodgkin lymphoma. Among the 25 patients studied, 22 had localized stage. Extranodal marginal zone lymphoma was the most frequent type of primary orbital and adnexal lymphoma. In this study localized disease was observed in most cases, and distant spread of the lymphomas was infrequent.
