[Chicken pox recurrence revealing a renal adenocarcinoma in an adult]

A new episode of chicken pox in adults who had a well documented infection previously is usually observed in immunocompromised individuals. The principal immunodeficiency factors are hematology diseases, acquired immunodeficiency disease and old age. We report here the case of a young woman who after a contaminating contact presented a recurrence of typical chicken pox. Morphological investigations evidenced a right kidney tumor which pathology revealed to be a renal adenocarcinoma. We discuss this pathological association and review cases reported in the literature.
