A Case of Spheroidal-Cell Carcinoma (Seminoma) of the Epididymis A CASE OF SPHEROIDAL-CELL CARCINOMA (SEMINOMA) OF THE EPIDIDYMIS A. A. EIHENBEHG, M.D., IRVING SIMONS, M.D., AND IL\ItHy WALLERSTEIN, M.D. (Proll! the Sydenhalll Hospital, New York) The following case is reported because of the extreme rarity of this type of spheroidal-cell carcinoma (seminoma) in the epi­ didymis. FlU. 1. SPHEROIDAL-CELL CARCINOMA OF THE EPIDIDYMIS: UNOPENED SPECIMEN. A. EPIDIDYMIS. B. TESTIS CASE REPORT The patient, Louis W., aged forty-eight, was admitted to the Syden­ ham Hospital (Case No. 19866), to the service of Dr. A. Lightstone,' on Nov. 5, 1931. 1 Dr. Lightstonc's kind permission to report this case is gratefully acknowledged. 875 876 A. A. EISENBERG, IRVING SIMONS, AND HARRY WALLERSTEIN History: One year previously the patient had observed swelling and some pain in the right testicle. There had been no trauma, and no inflammation. Venereal disease was denied. Recently the swelling had increased in size. FlO. 2. SPHEROIDAL-CELL CARCINOMA OF THE EPIDIDYMIS: OPENED SPECIMEN. A. EPIDIDYMIS. B. TESTIS Physical Examination: The general condition was normal. The penis and left testicle were normal, but the right testicle showed a hard lump, the size of a hazelnut, at the upper pole, apparently involving the epididymis. It did not involve the skin, and did not transilluminate. A few" shotty" lymph nodes were palpable in the right inguinal region. Preoperative Diagnosis: Carcinoma of testicle or tuberculosis of the epididymis. Operation: On Nov. 6, 1931, under local anesthesia, the right testicle and the vas deferens as far as the internal inguinal ring were removed. The patient left the hospital Nov. 11, 1931, and returned later for deep x-ray therapy. Pathologic Study Gross: The specimen (7279) is a testicle with the epididymis attached (Fig. 1), the entire mass measuring 6.5 X 5 X 2 em. The testicle SPHEROIDAL-CELL CARCINOMA OF THE EPIDIDYMIS 877 measures 3 X 1.5 em.; the epididymis, 3.5 X 3 em. The testis appears normal except that it is compressed somewhat by the hard nodular epididymis above it. On section (Fig. 2) the cut surface of the testis is soft, homogeneous, and brownish-yellow; no nodules are seen in its FIG. 3. LOW-POWER VIEW OF SECTION SHOWING ATROPHIC TESTICLE ABOVE AND SPHEROIDAL-CELL CARCINOMA OF EPIDIDYMIS BELOW, WITH AN INTERVENING FIBROUS CAPSULE parenchyma. A thick capsule separates it from the epididymis. The latter is firm, except for an occasional area of softening, brownish in color, and presents a fleshy sarcoma-like appearance identical with that seen in spheroidal-cell carcinoma of the testis proper. Microscopic: Sections (Figs. 3-5) show that the epididymis is entirely converted into a neoplasm consisting of large cells, some of which are 878 A. A. EISENBERG, IRVING SIMONS, AND HARRY WALLERSTEIN round and others polyhedral. There is a distinct uniformity in the type of the cell, which has a clear cytoplasm with a large nucleus con­ taining considerable chromatin material and in some cases filling almost the entire cell. These cells form large masses with no tendency toward FlOS. 4 AND 5. SPIiEROlDAL-CELL CARCINOMA m' THE EPIDIDYMIS, X 200 AND X 300 grouping or alveolar arrangement, A small amount of stroma is present, and this is infiltrated with small lymphocytes. A few areas of necrosis are seen. Separating the epididymis from the testicle is a thick layer of fibrous tissue, which is not invaded by neoplastic cells. The testis proper is not infiltrated by the neoplasm, several sections failing to show SPHEROIDAL-CELL CARCINOMA OF THE EPIDIDYMIS 879 carcinomatous involvement. There is, however, a good deal of fibrous tissue in the testis, the tubules being atrophied. Diagnosis: Spheroidal-cell carcinoma of the epididymis, not involving the testis. DISCUSSION A search of the medical literature shows that since 1881 there have been twenty reports, presenting 23 cases of malignant neo­ plasms of the epididymis, as follows: No. of Cases SARCOMA •••••••...............•........... '" ..........•..•..• 12 Sarcoma (unqualified) 4 Cystic sarcoma 2 Round-cell sarcoma 2 Melanosarcoma 2 Mixed-cell sarcoma 1 Chondrosarcoma 1 CARCINOMA. .••.............................................. .. 7 Carcinoma (unqualified) 1 Columnar carcinoma 1 Squamous-cell epithelioma 1 Epithelioma 1 Basal-cell carcinoma 1 Adenocarcinoma 2 TERATOMA ••......••........................................•.• 2 Teratoma (unqualified) 1 Malignant teratoma 1 SEMINOMA (EMBRYONAL CARCINOMA) .......•.......•..........•..• 2 TOTAL .••.•••................•..........................23 Of these 23 cases, 2 are authentic cases of spheroidal-cell carcinoma (seminoma or embryonal carcinoma) as evidenced by photomicro­ graphs. The case here reported is the third authentic case. Some of the older cases up to twenty-five years ago are difficult to pass judgment upon, as most of the histologic pictures are from drawings. Also the nomenclature of this earlier period makes it difficult to decide as to the exact character of the neoplasms. It is probable that some of the sarcomata were really carcinomata. It is also probable that such tumors as were called cystosarcoma and chondrosarcoma may have been mixed tumors of the type to-day called embryomata. The only authentic cases of spheroidal-cell carcinomata are that of Hinman and Gibson (Case 3), and that of Coleman, Mackie and Simpson. 880 A. A. EISENBERG, IRVING SIMONS, AND HARRY WALLERSTEIN It is not our desire to enter into the controversy, as to whether there is but one malignant testicular tumor (teratoma), or two distinct types (embryoma and seminoma). By using the term spheroidal-cell carcinoma, rather than seminoma, the question of the origin of the neoplasm from cells of testicular tubules is avoided. The neoplasm reported here is certainly identical with those of like histology occurring in the testicle. The presence of such a tumor in the epididymis need not, in our opinion, invalidate the idea of the development of such a tumor from the epithelium of testicular tubules, as it is not impossible that such tubules may have been misplaced in the development of the testicle. At any rate, it does not seem likely that the reported tumor developed from epididymal duct epithelium. An interesting development in this case is the presence of a hormone reaction. Dr. Russel S. Ferguson, who was kind enough to perform the Aschheim-Zondek test, reported it strongly positive, and this despite the fact that the patient has been receiving deep x-ray therapy since operation. This would suggest that metastases have already occurred. CONCLUSIONS 1. A case of spheroidal-cell carcinoma of the epididymis is reported. It is the third case to be described. 2. The tumor, in its gross and microscopic nature, is identical with the neoplasm of the same name that appears in the testicle. 3. The use of the term spheroidal-cell carcinoma avoids the controversy as to the origin of this tumor implied in the terms seminoma and embryonal carcinoma. 4. The Aschheim-Zondek reaction is a valuable aid in the prognosis of spheroidal-cell carcinoma of the testis and epididymis. BIBLIOGRAPHY (Case reports of malignant neoplasms of the epididymis) 1.

We investigated the immunohistochemical expression of these markers in different testicular germ cell tumors, and their utility in the differential diagnosis of morphologically difficult-to-classify components of these tumors. A total of 50 mixed testicular germ cell tumors, 43 also containing difficult-to-classify areas, were studied. In these areas, multiple morphological parameters were noted, and high-grade nuclear details similar to typical embryonal carcinoma were considered ‘embryonal carcinoma-like high-grade’. Immunohistochemical staining for OCT3/4, c-kit, CD30, SOX2, and GDF3 was performed and graded in each component as 0, negative; 1 þ , 1–25%; 2 þ , 26–50%; and 3 þ , 450% positive staining cells. The different components identified in these tumors were seminoma (8), embryonal carcinoma (50), yolk sac tumor (40), teratoma (40), choriocarcinoma (3) and intra-tubular germ cell neoplasia, unclassified (35).

Research and Statistics See the latest estimates for new cases of testicular cancer and deaths in the US and what research is currently being done. ● Key Statistics for Testicular Cancer ● What’s New in Testicular Cancer Research? What Is Testicular Cancer? Cancer starts when cells begin to grow out of control. Cells in nearly any part of the body can become cancer and spread to other parts of the body. To learn more about how cancers start and spread, see What Is Cancer?1 Cancer that starts in the testicles is called testicular cancer. To understand this cancer, it helps to know about the normal structure and function of the testicles. 1 ____________________________________________________________________________________American Cancer Society cancer.org | 1.800.227.2345 What are testicles? Testicles (also called testes; a single testicle is called a testis) are part of the male reproductive system. The 2 organs are each normally a little smaller than a golf ball in adult males. They're held within a sac of skin called the scrotum. The scrotum hangs under the base of the penis. Testicles have 2 main functions: ● They make male hormones (androgens) such as testosterone. ● They make sperm, the male cells needed to fertilize a female egg cell to start a pregnancy. Sperm cells are made in long, thread-like tubes inside the testicles called seminiferous tubules.

  • Testicular Seminomatous Mixed Germ Cell Tumor with Choriocarcinoma
    Aneja et al. Journal of Medical Case Reports 2014, 8:1 JOURNAL OF MEDICAL http://www.jmedicalcasereports.com/content/8/1/1 CASE REPORTS CASE REPORT Open Access Testicular seminomatous mixed germ cell tumor with choriocarcinoma and teratoma with secondary somatic malignancy: a case report Amandeep Aneja1*, Siddharth Bhattacharyya1, Jack Mydlo2 and Susan Inniss1 Abstract Introduction: Testicular tumors are a heterogeneous group of neoplasms exhibiting diverse histopathology and can be classified as seminomatous and non-seminomatous germ cell tumor types. Mixed germ cell tumors contain more than one germ cell component and various combinations have been reported. Here, we present a rare case of a mixed germ cell tumor composed of seminoma, choriocarcinoma and teratoma with a secondary somatic malignancy. Case presentation: A 31-year-old Caucasian man presented with splenic rupture to our hospital. A right-sided testicular swelling had been present for 6 months and his alpha-fetoprotein, beta-human chorionic gonadotropin, and lactose dehydrogenase were increased. An ultrasound of his scrotum revealed an enlarged right testis with heterogeneous echogenicity. Multiple hypervascular lesions were noted in his liver and spleen. He underwent transcatheter embolization therapy of his splenic artery followed by splenectomy and right-sided orchiectomy. A computed tomography scan also showed metastasis to both lungs. During his last follow up after four cycles of cisplatin-based chemotherapy, the level of tumor markers had decreased, decreases in the size of his liver and pulmonary lesions were noted but new sclerotic lesions were evident in his thoracolumbar region raising concern for bony metastasis. Conclusions: Prognosis of testicular tumor depends mainly on the clinical stage, but emergence of a sarcomatous component presents a challenge in the treatment of germ cell tumors and the histological subtype of this component can be used as a guide to specific chemotherapy in these patients.

MADEJ Department of Pathology, ¹Department of Surgery, ²Department of Reproduction and Clinic of Farm Animals, Faculty of Veterinary Medicine, Wroclaw University of Environmental and Life Sciences, 50-375 Wroclaw, Poland [email protected] Received: April 27, 2012 Accepted: September 7, 2012 Abstract The study aimed at presenting the most frequent male gonadal tumours in dogs, their clinical and histopathological aspects, at outlining aetiopathogenesis and differential diagnosis of the tumours. As examples of the most frequently manifested testicular tumours, three clinical cases were presented, involving tumour of interstitial (Leydig) cells, tumour of Sertoli cells, and seminoma. Respective clinical diagnosis employed USG, X-ray patterns, and morphological and biochemical tests. The surgically sampled material was stained with H+E and an attempt was made to establish expression of E-cadherin, calretinin, and Ki-67. It was shown that histopathological diagnosis of testicular tumours in dogs is frequently very difficult and complex and requires multidirectional studies. Key words: dogs, seminoma, sertolioma, leydigoma, calretinin, E-cadherin. Testicular tumours used to be encountered significant effect on the development of leydigomas (5, relatively frequently in household animals and the 34). lesions are most frequently noted in dogs (14, 19, 22, 23, An increased risk of testicular tumour 25, 35). On grounds of multi-year studies of Nielsen et development can be noted in morbid syndromes linked al.
