Testicular lymphoma: a literature review and report of a case with a zoster-like cutaneous recurrence.

Testicular lymphoma accounts for approximately 1% of all cases of non-Hodgkin's lymphoma. This distinct clinical entity can have an aggressive course with a high rate of systemic relapse. We describe a unique case of a diffuse large B-cell lymphoma, T-cell-rich variant with cutaneous dermatomal zosteriform recurrence presenting as neuralgia. This case represents a unique pattern of treatment failure in this aggressive extranodal lymphoma.
