NCIt definition : A distinctive variant of follicular lymphoma arising from the testis. It has been
reported with higher frequency in children, but is also seen rarely in adults. It
differs biologically from nodal follicular lymphoma because it lacks evidence of the
BCL2 translocation. It is usually of high cytological grade, usually grade 3A, but
has a good prognosis, even without additional therapy beyond surgical excision. (WHO
2017);
