1. This is a clinical and pathological report of an adenocarcinoma of the right epidydimis which deals with a patient of one year and nine months old boy. He was operated on two week later from the onset of the swelling of that region and no evidence of metastasis after four months, follow up. 2. Grossly the tumor shows rather close relationship with the right side epidydimis than tunica vaginalis and measures 3 × 2.5 × 2 cm in its overall dimensions and covered by thin layer of membranous tissue. Histologically the tumor is composed of various areas one of which is a feature of carcinoma of glandular type and the other of which is hemangiomatous and occasional solid cell nests. The cells of the tumor shows atypicality of nuclei: large size of the nucleus in comparison with an amount of the cytoplasma present, moderate hyperchromatism, coarse chromatin and occasional mitotic figure. No extension beyond the covering tissue. 3. As to the histologic origin of this type tumor the epithelial origin should be taken in consideration rather than mesothelial one. Although the tumor exhibitis in a majority of areas a feature of angiomatous one the authers assume it as a carcinoma of glandular type because there is lacking. lymphoid tissue and peculiar large cells in the stroma of the tumor. No contributory in the past history in regards to the pathogenesis of the tumor such as a trauma or long standing inflammatory responce.
