Evaluation of commercial immunoperoxidase kits for prostatic specific antigen and prostatic specific acid phosphatase

Relationship between histologic grading and serum prostate specific antigen in prostatic carcinoma

Prostate specific antigen (PSA) is the most important tumour marker which, used routinely, proved to have a positive correlation with tumour volume and pathological stage. To evaluate the relationship between serum PSA and histologic grading of prostatic carcinoma, preoperative PSA determinations were made in 25 patients with prostatic cancer. Biopsy materials were evaluated and the Gleason scores were adjusted for histologic grading. The higher values of PSA were proportional to the Gleason scores of the primary prostatic biopsy.

Prostate specific antigen and prostate specific acid phosphatase in adenocarcinoma of Skene's paraurethral glands and ducts

An autopsy case of adenocarcinoma of Skene's paraurethral gland co-incident with renal cell carcinoma is described. The adenocarcinoma showed distinct prostate specific antigen and prostate specific acid phosphatase pointing to the equivalence between the male prostate and Skene's paraurethral glands and ducts. Skene's gland are the homologue of the prostate in females and tumours arising from them are immunohistochemically similar to male prostate carcinoma.

Tumour of female paraurethral duct. Immunohistochemical similarity with prostatic carcinoma

A case of adenocarcinoma derived from a female paraurethral duct is described. Morphologically the tumour looked like a prostatic adenocarcinoma. Furthermore, the tumour cells stained positively with antibodies to prostatic specific antigen and prostatic specific acid phosphatase. The karyotype of the patient was 45,x/46,xx/47,xxx/46,xt(x;13)(p11;q22) demonstrating that the patient was not a hermaphrodite. The tumour therefore represented female homology of a prostatic adenocarcinoma.
