Marcaje de leucocitos con 99mTc-exametazima y policitemia vera: un hallazgo casual

Abstract

La clasificación oficial de la Organización Mundial de la Salud de los tumores de tejidos hematopoyéticos y linfoides de 2016 introduce el concepto de policitemia vera (PV) enmascarada y revela que esta entidad ha sido infradiagnosticada en el pasado. Se presenta el caso de un varón de 49 años, fumador, intervenido de fractura de tobillo hace más de 15 años, remitido para valorar un posible proceso infeccioso asociado. Al no producirse separación previa de los hematíes por sedimentación durante el procedimiento de marcaje de leucocitos con 99mTc-exametazima se revisaron las causas de disminución de la velocidad de sedimentación globular. Entre ellas destacan la poliglobulia y el hábito tabáquico, ambas presentes en el paciente. Se recomendó realización de estudio hematológico que concluyó con el diagnóstico de PV. Las indicaciones del especialista en Radiofarmacia permitieron diagnosticar un caso no identificado hasta entonces, pese a que el paciente presentaba síntomas desde hacía años.

The official World Health Organization classification of hematopoietic and lymphoid tissue tumors introduces in 2016 the concept of masked polycythemia vera (PV) and reveals that this entity has been underdiagnosed in the past. We present the case of a 49-year-old man, smoker, operated on for ankle fracture more than 15 years ago, referred to evaluate a possible associated infectious process. As there was no previous separation of the red blood cells by sedimentation during the leukocyte labelling procedure with 99mTc-exametazima, the causes of decreased erythrocyte sedimentation rate were reviewed. These include polyglobulia and smoking, both present in the patient. A haematological study was advised, which concluded with the diagnosis of PV. The indications of the specialist in Radiopharmacy allowed diagnosing a case not identified until then, although the patient had had symptoms for years.
