Abstract

Adenomatoid tumors arising in the parenchyma of the testes are extremely rare neoplasms, and they uniformly behave in a benign fashion. The long reorted history of these tumors and the absence of distant metastasis suggest a benign nature. Thus, the treatment is surgical excision. We report here on a case of an adenomatoid tumor of the testis. Radical orchiectomy was performed, and this revealed an adenomatoid tumor of the parenchyma of the testis.

• 

  Fig. 1 Scrotal ultrasonography shows an approximately 0.8cm sized ovoid mass with a homogeneous echotexture, and there was no evidence of abnormal fluid collection.

• 

  Fig. 2 The vacuoles replaced most of the cytoplasm and the nuclei show marked uniformity in size and chromatin distribution (H&E, ×400).
