Fusion of the testis with adrenal remnants is a relatively common incidental finding during orchidopexy. Splenogonadal fusion has been described in several cases. Herein the authors report a case of hepatogonadal fusion. To their knowledge, this is the first such case in the literature. Ectopic liver tissue has been encountered in a variety of locations, but had not been found in a testicle. The trapping of hepatocyte-destined mesenchyma in different areas may explain the presence of heterotopic liver tissue in different organs. If these cell aggregates are trapped in the area of peritoneum where the testis is forming, heterotopic liver tissue can end up in the testis.

The 4th case of plasma cell neoplasm associated with a hypereosinophilic syndrome is described and compared with the previous reports. Hypereosinophilia in the present patient displayed some borderline traits with eosinophilic leukemia. Myeloproliferative disorders of the eosinophilic line often present as a precancerous state, but sometimes they seem to acquire malignant independence. In our patient the occurrence of a plasmocytoma with a dramatic course leads to suspect an underlying complex genetic aberration.
