SUMMARYTwo autopsy-proved cases are presented of a rare form of congenital heart disease, anatomically corrected malposition IS, D

Immunohistologic studies were performed on autopsy tissues of 2 patients with systemic lupus erythematosus. All tissues examined-the kidney, lung, spleen, liver, intestine, peritoneum, and choroid plexus-contained immune deposits. Antinuclear antibody concentration in immunoglobulin G eluted from lung and spleen tissue was higher than in serum immunoglobulin G. These findings support the assumption that in systemic lupus erythematosus the renal as well as the extrarenal lesions can be attributed to vascular deposition of immune complexes.

Scrotal masses are a common problem in children. Cystic lesions usually are found to be hydroceles, while solid masses suggest the possibility of neoplasia. A rare cause of a cystic scrotal mass is ectasia of the rete testis. A review of the literature reveals only 1 case similar to the patient herein described. Both patients had agenesis of the ipsilateral kidney, which explained on the basis of the embryologic overlapping of the genitourinary system. Our patient bears clinical similarity to the ACI rat and correlation is made with this animal model system. Excision of the multiloculated rete testis cyst, rather than orchiectomy, appears to be curative.
