Primary non-hodgkin lymphoma of breast in a patient with rectal carcinoma and magnetic resonance spectroscopic examination

Abstract

A 62-year-old woman being treated for stage IIIC rectal adenocarcinoma was diagnosed with primary non-Hodgkin lymphoma of the breast after a 4-year follow-up. This case illustrates the importance of close and long-term follow-up as well as of differential diagnostic procedures for second primary malignancies after the initial diagnosis and treatment of a solid tumor.
