Differential diagnosis of testicular mass by cytological examination of seminal fluid collected by ejaculation or prostatic massage.
The cytological examination of the seminal fluid of 3 patients with painless testicular masses was performed using an ordinary conventional technique. Neoplastic cells appeared in the ejaculate or fluid from prostatic massage of all patients. The final pathologies were seminoma, choriocarcinoma and mixed teratocarcinoma. Malignant cells were no longer found in the seminal fluid after orchiectomy. This sample, noninvasive technique plus further flow cytometric study of cellular DNA contents is a great help in the preoperative differential diagnosis of testicular masses.
