Testicular pseudolymphoma.
Pseudolymphomas are reactive processes which by their morphology can be confused with lymphomas. They have been described in non-lymphoid organs (gastrointestinal tract, lung, breast, etc.), although cases have also been reported in the spleen. In this article we present the case of a 3-year-old child in whom the location was in the testes. It is the 4th case reported in the literature and the first in a child. The main criteria for establishing such a diagnosis are the delimitation of the lesion, the presence of mature lymphocytes intermingled with other cells which are mainly plasma cells of polyclonal type and the formation of lymphoid follicles with active germinal centers. A differential diagnosis within the testicle should be made with the lymphoma (primary or secondary), the leukemic infiltration and the seminoma with marked stromal lymphoid reaction.
