Fine-needle aspiration of testicular lesions: Report of 17 cases

Abstract

In this article we report on our diagnostic experience of fine-needle aspiration biopsies (FNAB) performed on 17 patients with testicular lesions in the period from 1994-1998. The cytological diagnosis was consistent with seminoma in 7 cases, sex cord-stromal tumors in 3 cases (2 Sertoli cell tumors, 1 Leydig cell tumor), embryonal carcinoma in 3 cases, and yolk-sac tumor in 1 case; the other 3 patients were suffering from flogistic pathology. The cytological diagnosis was confirmed in all cases after surgery. According to our experience, ultrasound FNAB of testicular lesions proved to be a very reliable technique in predicting malignancy with high sensitivity and specificity. None of the patients developed local recurrences or inguinal lymph-node metastasis due to FNAB. Therefore, tumor stage classification (TNM) was not modified in any patient.
