GARCIA PENALVER, Cristóbal et al. Primary testicular lymphoma with extranodal involvement. Arch. Esp. Urol. [online]. 2009, vol.62, n.6, pp.489-493. ISSN 0004-0614.

We report the case of a 65-year-old man who presented with a right testicular mass and synchronous involvement of skin and Waldeyer's ring. These facts led us to the working diagnosis of malignant primary testicular lymphoma. Material/Results: We present the case with comments and make a bibliographic review of the disease. Conclusions: Primary testicular lymphoma is an uncommon testicular tumour that accounts for not more that 9% of all testicular tumours in the series with higher incidence. Testicular lymphomas are also rare among haematopoietic tumours, accounting for just 1% of all lymphomas, but due to their highly malignant histopathology they may become highly aggressive tumours. Patient age at presentation is over 60 years which makes it the most frequent tumour for this age group. 70% of recently diagnosed patients show Ann Arbor stages I and II. Tumours in advanced-stage have a predilection for spreading to extranodal sites such as central nervous system, skin, Waldeyer's ring and lungs.
