Abstract
Abstract
Spermatocytic tumor is a rare testicular tumor, which is originated from gonocytes. It is characterized by the histological feature of tripartite which is composed of large, medium, and lymphocyte-like small cells. It is well-known that spematocytic tumor is benign, thus a good prognosis is expected after simple resection. Metastatic spermatocytic tumor is extremely rare and usually accompanied by histological variants including sarcomatous changes and anaplastic variants. In this case, however, we report a canine metastatic spermatocytic tumor without prominent sarcomatous changes and anaplastic variants. The mass was composed of three kinds of cells including large, medium, and small cells with high pleomorphism. The neoplastic cells had an indistinct cytoplasmic border and mitotic figures were frequently observed. The primary spermatocytic tumor metastasized to the abdominal organs one month after the resection, and the dog died 13 months after the surgery. Thus, careful follow-up is recommended after surgical resection of canine spermatocytic tumor even though metastasis in spermatocytic tumors is rare.

A systematic review of treatment outcomes in localised and metastatic spermatocytic tumors of the testis. J Cancer Res Clin Oncol 2019; 145:3037-3045.

Abstract
INTRODUCTION Because spermatocytic tumors of the testis are rare, only limited evidence exists regarding the malignant potential and the optimal management of localized and metastatic disease. MATERIALS AND METHODS We performed a systematic review through MEDLINE, EMBASE, Scopus, Cochrane Database of Systematic Reviews and Web of Science to identify reports including patients with testicular spermatocytic tumors. RESULTS From originally 7863 studies, we extracted data of 146 patients of which 99% were treated with radical orchiectomy. Metastases in patients with initially localised disease were diagnosed in 7% of patients and detected after a median follow-up of 5.5 months (range 2-21 months). Patients with aggressive histology (sarcoma or anaplastic subtype) were more likely to have metastatic disease (6/124 (5%) vs 9/22 (41%), p < 0.001). Patients with metastatic disease had larger primary tumors (92.5 vs 67.5 mm, p = 0.05). Life expectancy in patients with metastatic disease ranged from 1 to 25 months. CONCLUSION The published literature does neither support the use of testis sparing surgery nor adjuvant therapy. Patients with aggressive variants or larger tumors were more likely to have metastases and develop recurrences within the first few years. Patients with metastatic disease have a limited life expectancy and metastatic spermatocytic tumors are not as responsive to chemotherapy as germ cell cancers.

Abstract
Spermatocytic seminomas affect 0.3-0.8 per one million men. This tumor is not, as the name might suggest, a variant of classical seminoma but a distinct nosological entity, which differs markedly from all other germ cell tumors in its epidemiology, peculiar morphology, oncogenesis and clinical outcome. There are no racial differences in the incidence and risk factors are completely unknown. Patients are significantly older than is the case for other germ cell tumors with an average of 53.5 years; nevertheless, more than 25 % are younger than 40 years. Spermatocytic seminoma arises from differentiated spermatogonia, not from intratubular germ cell neoplasms. The tumor-specific gain of chromosome 9 seems to be the most important event in the oncogenesis. Conventional spermatocytic seminoma consists of three different cell types which give the tumor a highly aggressive appearance, although in actual fact, the tumor has a very favorable outcome, with few reported cases of general metastatic spread. Anaplastic spermatocytic seminoma, a recently described variant, also takes mostly a benign course; however, spermatocytic seminomas combined with sarcomas are extremely malignant.

Abstract
Spermatocytic seminoma (SS) is a rare entity, accounting for 2%-12% of all seminomas; amongst those, fewer than 10% are bilateral. These may occur synchronously or metachranously. We report here a case of bilateral SS in a 63-year-old patient, who initially presented with bilateral testicular masses. In our search of the literature, this represents the fifth documented case of synchronous, bilateral SS.

Cancer testis antigen expression in testicular germ cell tumorigenesis. Mod Pathol 2014; 27:899-905.

Abstract
Cancer testis antigens are encoded by germ line-associated genes that are present in normal germ cells of testis and ovary but not in differentiated tissues. Their expression in various human cancer types has been interpreted as 're-expression' or as intratumoral progenitor cell signature. Cancer testis antigen expression patterns have not yet been studied in germ cell tumorigenesis with specific emphasis on intratubular germ cell neoplasia unclassified as a precursor lesion for testicular germ cell tumors. Immunohistochemistry was used to study MAGEA3, MAGEA4, MAGEC1, GAGE1 and CTAG1B expression in 325 primary testicular germ cell tumors, including 94 mixed germ cell tumors. Seminomatous and non-seminomatous components were separately arranged and evaluated on tissue microarrays. Spermatogonia in the normal testis were positive, whereas intratubular germ cell neoplasia unclassified was negative for all five CT antigens. Cancer testis antigen expression was only found in 3% (CTAG1B), 10% (GAGE1, MAGEA4), 33% (MAGEA3) and 40% (MAGEC1) of classic seminoma but not in non-seminomatous testicular germ cell tumors. In contrast, all spermatocytic seminomas were positive for cancer testis antigens. These data are consistent with a different cell origin in spermatocytic seminoma compared with classic seminoma and support a progression model with loss of cancer testis antigens in early tumorigenesis of testicular germ cell tumors and later re-expression in a subset of seminomas.

Abstract
Background Spermatocytic seminoma (SS) is a distinct testicular germ cell tumor, representing less than 1% of testicular cancers. The clinical features that distinguish ss from classical seminoma are an older age at presentation and a reduced propensity to metastasize. The aim of our work is to underline the epidemiological, clinical, histological, therapeutical and prognostic features of this tumor. Findings A retrospective analysis of patients referred to the national institute of oncology with seminoma, identified from the institutional tumor registry, between January 1996 and February 2009, was performed. Information reviewed included demographics, clinical, pathological staging, surgical management, adjuvant treatment and last follow-up. We studied four cases of spermatocytic seminoma, which represented 1% of testicular tumor and 6,4% of all seminoma treated at our institution during the study period. Median age at diagnosis was 45 years (range: 42-48). Mean delay before consulting was 9 months and the mean tumor size was 13,75 cm (10-18 cm). No patient had a history of maldescended testis. The main clinical complaint was unilateral testis mass with low progression. Pathology showed that tumors had a polymorphic appearance with small, intermediate and large cells. In all cases, the tumor was limited to the testis. immunohistochemical studies showed that tumors were negative for all the classical antibodies tested (LCA, cytokeratins, PLAP, lymphoid markers, CD117). Thoraco-abdomino-pelvic CT scan and tumor markers (AFP and hCG) were normal. All patients were Stage I. Treatment consisted on an orchidectomy associated with adjuvant radiotherapy in one patient. After a median follow-up of 6 years ranging from 2 to 15 years, we did not note any relapse or metastasis. Conclusion The diagnosis of spermatocytic seminoma must be considered in all patients aged of more than 50 with testicular tumor. With only three cases of metastatic disease confirmed in the literature, this is a subgroup of patients in whom radiotherapy can safely be omitted.

Abstract
The aims of this paper were to review the literature of Spermatocytic Seminoma (SS) updating its clinico-pathological features and to present a new case of the exceptionally rare variant of this tumor known as anaplastic which only five cases have been reported. Many studies have confirmed that SS is a distinct neoplasm both clinically and pathologically from classical Seminoma and it differs from the latter especially in regard to behavior, characterized by an almost complete inability to metastasize with only very few convincing examples described with metastatic behavior. There is general agreement that orchidectomy is sufficient therapy for SS and that surveillance following surgery is the preferred management option. Surprisingly, the presence of an anaplastic component does not seem to impact on this excellent prognosis. Very different is the case of sarcomatous transformation, for which further therapy after orchiectomy is advisable.

Abstract
Metastatic spermatocytic seminoma is an extremely rare disease. No chemotherapeutic regimen is established and the use of adjuvant radiation therapy after orchiectomy as frequently performed for classical seminoma is unclear. We report the third case of proven spermatocytic seminoma metastatic in the literature and provide a review of the literature. Administering BEP polychemotherapy as in classical seminoma was poorly effective in reducing the retroperitoneal mass in a patient with spermatocytic seminoma. A review of the literature showed that all the three described patients developing metastatic disease did not receive adjuvant radiation therapy after orchiectomy, which might be considered in high-risk cases.

Abstract
Recent advances in the understanding of the molecular pathology of testicular tumours have led to the identification of several new immunohistochemical markers for invasive and in situ germ cell neoplasms. OCT3/4 and NANOG are nuclear stains that have high sensitivity and specificity for the identification of intratubular germ cell neoplasia as well as seminoma and embryonal carcinoma. A potential pitfall in their application to the detection of intratubular germ cell neoplasia, as in other markers that represent oncofetal antigens, is their expression in non-neoplastic germ cells with 'delayed maturation'. SALL4, another nuclear stain, is positive for most germ cell tumours as a group and may be especially helpful in the distinction of these tumours from somatic carcinomas in non-testicular sites. Glypican 3 is a more sensitive marker for yolk sac tumour than alpha-fetoprotein. SOX2 and SOX17 may be useful for differentiating seminoma and embryonal carcinoma, especially following chemotherapy as embryonal carcinoma may lose CD30 expression in this setting. This article reviews the application of these immunohistochemical markers and others to the diagnosis of germ cell neoplasia with reference to older immunohistochemical stains when appropriate. Suggested immunohistochemical panels are described for individual tumour types.

Abstract
Abstract
Spermatocytic seminoma is a rare germ cell tumor distinct from classical seminoma, both clinically and pathologically. It affects older men, has not been associated with a history of cryptorchidism, and has no known counterpart in ovary or any other site. Pathologically, it is characterized by 3 distinct cell types, lack of cytoplasmic glycogen, and scant to absent lymphocytic infiltrate. Gain of chromosome 9 is the most consistent genetic abnormality. There have been few case reports of sarcomas arising in spermatocytic seminoma and only an occasional report of metastasis. It is important to differentiate this condition from its frequent mimics, such as classic seminoma and embryonal carcinoma, because patients with spermatocytic seminoma may not require further treatment after surgery.

Abstract
CONTEXT More than 90% of testicular neoplasms originate from germ cells. Testicular germ cell tumors (GCTs) are a heterogeneous group of neoplasms with diverse histopathology and clinical behavior. OBJECTIVE To help the readers distinguish various subtypes of GCTs, to highlight the clinical manifestations and pathologic features of these tumors, and to review several newly developed immunohistochemical markers for GCTs. DATA SOURCES Review of the pertinent literature and our experience. CONCLUSIONS The etiology of GCTs is largely unknown. Cytogenetic studies suggest a different pathogenesis for each group of infantile/prepubertal GCTs, postpubertal GCTs, and spermatocytic seminoma. Unclassified intratubular germ cell neoplasia is the precursor of all GCTs, excluding spermatocytic seminoma and infantile/prepubertal GCTs. Seminoma, the most common GCT in adults, does not occur before 5 years of age. Spermatocytic seminoma, a tumor of elderly men, typically has an indolent clinical behavior, but rarely it undergoes sarcomatous transformation associated with an aggressive behavior. Embryonal carcinoma is the most common component in mixed GCTs. Eighty percent or more of embryonal carcinoma component and vascular invasion are recognized predictors of occult metastasis for clinical stage I mixed GCTs. Most patients with prepubertal yolk sac tumor, the most common pediatric GCT, have stage I disease at presentation. Most choriocarcinomas present with metastatic symptoms because of the propensity for rapid hematogenous dissemination. Teratomas in children regardless of maturity and dermoid cysts in adults are benign; in contrast, teratomas in adults have a malignant behavior. With appropriate therapy, the majority of testicular GCTs are curable.

Abstract
We report a case of a 56-year-old male with an anaplastic variant of spermatocytic seminoma of the left testis. Grossly, the tumor measured 10 x 7.5 x 6.5 cm and consisted of soft grayish-white tissue, which varied from fleshy to gelatinous with formation of some pseudocysts. Histologically, the tumor was composed of the areas of typical spermatocytic seminoma; however, in some areas, the intermediate and large tumor cells showed prominent nucleoli. In another part of the tumor, we noted anaplastic areas composed of sheets of tumor cells with large vesicular nuclei and prominent nucleoli. Tunical and vascular invasion as well as growth into the epididymis were noted. Immunohistochemically, the tumor cells showed only weak positivity for CD117, the other markers examined were negative.

Abstract
Testicular seminoma represents a modern model of a multidisciplinary approach to a curable neoplasm. Surgeons, radiation oncologists, and medical oncologists play an important role in disease detection, diagnosis, treatment, and follow-up. This article focuses on the management of men who have early-stage seminoma, which represents stage I and IIa (minimal retroperitoneal spread). In stage I disease, the major controversies continue to revolve around surveillance versus adjuvant treatment and more recently adjuvant radiotherapy or carboplatin-based chemotherapy. Focus on long-term complications, such as cardiovascular disease, gastrointestinal disease, and secondary cancers, has led to the concept of increased surveillance with therapy for those who relapse. Radiation therapy remains the mainstay of therapy for patients who have stage IIa disease.
