Abstract
We have experienced a case of testicular tumor, which was suggestive of malignant lymphoma through the cytological examination of hydrocele fluid.
The patient, 74 year-old man, was admitted to our hospital becouse of painless swelling of the testis. Orchiectomy was performed with histopathological diagnosis of malignant lymphoma, histiocytic type. Generally establishment of preoperative diagnosis of a testicular tumor is not easy and correct diagnosis is usually obtained by histological examination of the orchiectomized specimen. At this point, cytological examination of hydrocele fluid of the testicular tumor is very useful in early preoperative diagnosis. Furthermore we reviewed the literature of the other testicular tumors, compared with malignant lymphoma, and discussed the cytology of the hydrocele fluid.
