Resumen

ANTECEDENTES: la incidencia del linfoma no Hodgkin de mama es inferior a 0.5%. El diagnóstico preoperatorio es difícil de establecer, puede confundirse con el carcinoma mamario.

CASO CLÍNICO: paciente de 52 años de edad con tumoración en la mama izquierda valorada en la mamografía. En las pruebas complementarias se diagnosticó linfoma B folicular de bajo grado. Se realizó ROLL (Radioguided Occult Lesion Localization) mamario y axilar y posteriormente se indicaron radiaciones. 

CONCLUSIONES: es una enfermedad muy rara y no se dispone de estudios importantes para establecer el diagnóstico e indicar tratamiento.

PALABRAS CLAVE: linfoma no Hodgkin, mama.

Abstract

BACKGROUND: Extranodal lymphoma are rare, in particular, breast non-Hodgkin´s lymphoma has an impact of lower 0.5 %. It is difficult to diagnose during the pre-operative period, since it can be confused with breast carcinoma. 

CASE REPORT: A 52 years old female patient was sent due to a lump in her left breast identified in a mammogram. A study was conducted with supplementary tests, being eventually diagnosed as low-grade B-cell follicular lymphoma. She was subjected to a mammary and axillary radioguided occult lesion localisation (ROLL). After, radiation therapy was delivered. 

CONCLUSIONS: It is a very rare pathology, therefore, there is not relevant research to show effective treatment or diagnosis. 

KEY WORDS: Non-Hodgkin´s lymphoma; breast
