[A case of primary testicular diffuse large B-cell lymphoma with a p53 gene point mutation].

A 52-year-old man with bilateral swelling in the scrotum was referred to the department of urology in our hospital in January 2013. Pathological examination of the scrotum revealed diffuse large B-cell lymphoma(DLBCL). Immunohistochemical staining revealed p53 overexpression, and polymerase chain reaction-single strand conformation polymorphism(PCRSSCP) revealed a point mutation in exon 7 of the p53 gene.
