Abstract
A case is presented of a 50-year old man with a unilocular cystic intratesticular tumour exhibiting the morphological features demanded from WHO for the diagnosis of serous papillary cystadenoma of the ovary.
Keratin filaments could be demonstrated in the cyst lining and papillae covering cells by means of PAP-technique; AFP and SP-1 were lacking. The epithelial cells of the tumour showed a lectin binding pattern (WGA, UEA-1, PNA, Con A, PSA, LCA, RCA) different from the epithelium of rete testis and epididymis.
We intend to classify our tumour as the male analogue of the respective ovarian growth.
