Paratesticular papillary serous cystadenocarcinoma--a case report.

A case of paratesticular papillary serous cystadenocarcinoma in a six year old child is presented. The occurrence of these epithelial tumours of the ovarian type, in the paratesticular region is extremely rare and only six cases have been reported so far. They are thought to arise from Mullerian metaplasia of the peritoneal lining of the tunica vaginalis, appendix testis or mullerian remnants between the testis and spermatic cord.

In situ apoptosis in the thyroid.

Recent evidence has emphasized the importance of programmed cell death, or apoptosis, in the maintenance of tissue homeostasis and pathogenesis of tumors. This study analyzed the significance of apoptosis in relation to the expression of p53 and bcl-2 proteins, tissue proliferation defined by Ki-67 expression, and tissue histology in thyroid tissue. Extent of apoptosis was defined by morphological criteria and the terminal deoxynucleotidyl transferase-mediated deoxy uridine triphosphate (dUTP) biotin nick end labeling (TUNEL) assay.
