Abstract
BACKGROUND Yolk sac tumors (YST) are commonly encountered gonadal germ cell tumors in children, especially in the prepubertal age group. In addition to gonadal primary, it can occur in multiple extragonadal sites, of which sacrococcygeal, retroperitoneum, gastric and mediastinum are the commonest. There are 4 previous reports of primary penile YST. CASE REPORT We describe a primary penile yolk sac tumor in a child with achondroplasia. CONCLUSION Yolk sac tumor can occur in the penis during the prepubertal period. Penile yolk sac tumor associated with achondroplasia has not been previously reported, but this could be incidental.

Abstract
BACKGROUND Primary seminoma of the prostate (PSP) is a rare type of extragonadal germ cell tumour that is easily misdiagnosed, owing to the lack of specific clinical features. It is therefore necessary for clinicians to work toward improving the accuracy of PSP diagnosis.
CASE SUMMARY A 59-year-old male patient presenting with acute urinary retention was admitted to a local hospital. A misdiagnosis of benign prostatic hyperplasia led to an improper prostatectomy. Histopathology revealed PSP invading the bladder neck and bilateral seminal vesicles. Further radiotherapy treatment for the local lesion was performed, and the patient had a disease-free survival period of 96 mo. This case was analysed along with 13 other cases of PSP identified from the literature. Only four of the cases (28.6%) were initially confirmed by prostate biopsy. In these cases, imaging examinations showed an enlarged prostate (range 6-11 cm) involving the bladder neck (13/14). Of the 14 total cases, 11 (78.6%) presented typical pure seminoma cell features, staining strongly positive for placental alkaline phosphatase, CD117, and OCT4. The median age at diagnosis was 51 (range 27-59) years, and patients had a median progression-free survival time of 48 (range 6-156) mo after treatment by cisplatin-based chemotherapy combined with surgery or radiotherapy. The remaining three were cases of mixed embryonal tumours with focal seminoma, which had clinical features similar to those of pure PSP, in addition that they also had elevated serum alpha-fetoprotein, beta-human chorionic gonadotropin, and lactose dehydrogenase.
CONCLUSION PSP should be considered in patients younger than 60 years with an enlarged prostate invading the bladder neck. Further prostate biopsies may aid in proper PSP diagnosis. Cisplatin-based chemotherapy is still the main primary therapy for PSP.

Abstract
Extragonadal germ cell tumors (EGCTs) are uncommon, and those involving the prostate are rare. We report on a primary seminoma of the prostate in a 56-year-old male presenting with scrotal pain, urinary frequency and urgency, and erectile dysfunction. Digital rectal examination revealed a hard, markedly enlarged prostate projecting posteriorly into the rectum. All 12 cores from ultrasound-guided prostate biopsy revealed malignant cells that stained positive for OCT4, PLAP, and CD117. Imaging revealed a 10.2 cm x 7.8 cm x 8.4 cm prostate mass with irregular nodular margins extending superiorly to the base of the bladder and posteriorly abutting the anterior rectal wall. There was no evidence of distant metastatic disease on both nuclear medicine and CT scans of the chest, abdomen, and pelvis. An 11 mm right internal iliac lymph node and several tiny sub-centimeter external iliac nodes were noted bilaterally. The patient was treated with radiotherapy to the prostate and pelvic lymph nodes. The pelvic lymph nodes were treated with 20 Gy in eight fractions, followed by a boost to the prostate for a further 20 Gy in eight fractions. There was a significant response during treatment that allowed an adaptive boost for a further 10 Gy in four fractions to bring the total dose to the prostate to 50 Gy in 20 fractions. Treatment was well tolerated. Adjuvant chemotherapy was not recommended. He remains disease-free 24 months post-treatment. This case report indicates that like most seminomas, extragonadal seminomas are exquisitely sensitive to radiotherapy and may be considered for the primary treatment of non-metastatic disease. To our knowledge, this is the first reported case of the sole use of radiotherapy to treat a primary seminoma of the prostate.

Abstract
Prostatic yolk sac tumour is a germ cell tumour with a wide range of age of occurrence, unusual anatomic locations, diverse morphologic patterns, and aggressive biologic behavior, posing challenges both to diagnosis and clinical management. We report a rare case of primary yolk sac tumour of the prostate with extensive local and liver metastasis, the latter of which exhibited sheets of small blue cells expressing CD99 and focal sall4 on biopsy. Positivity for CD99 and gata3 in the initial biopsy raised the differential diagnosis of Ewing sarcoma and poorly differentiated carcinoma. The primary tumour demonstrated an admixture of solid and glandular growth patterns and occasional Schiller-Duval bodies. A panel of immunohistochemical stains showing positivity for AE1/3, sall4, cdx2, and focal alpha-fetoprotein, and negativity for oct-4, facilitated the diagnosis. A thorough review of the literature and our current report indicate that a large tumour load, incomplete tumour resection, limited response to preoperative neoadjuvant chemotherapy, and late stage of the disease are predictive factors for a poor clinical outcome.

Abstract
Extragonadal germ cell tumours (EGGCTs) originated in prostate are extremely rare, with <20 cases described in the literature. We report a case of a patient with a primary prostatic mixed EGGCT. A 47-year-old man presenting severe low urinary tract symptoms and signs of prostatic enlargement, with no malignancy suspicion, underwent transurethral resection of the prostate. The histopathological evaluation suggested the diagnosis of a retroperitoneal sarcoma. The patient underwent neoadjuvant chemotherapy and then was submitted to radical cystoprostatectomy. Histology revealed a mixed EGGCT of the prostate with yolk sac tumour and seminoma components. No testicular abnormalities were identified on the postoperative scrotal ultrasound. The patient went through four cycles of chemotherapy with bleomycin, etoposide and cisplatin. After 12 months of follow-up, the patient is alive and free of recurrence.

Abstract
A 69-year-old man presented with an incidental undifferentiated carcinoma of the prostate. Ten years ago the patient had clinical stage I seminoma of the right testis with adjuvant radiotherapy. Follow-up care was without pathological findings. Staging examinations did not show metastatic disease. After radical prostatectomy with pelvic lymphadenectomy, the histological examination revealed a metastatic seminoma in the prostate. Therefore, the diagnosis was a late relapse in an extremely rare location. So far only four other reports describe testicular seminoma with metastases to the prostate.

Abstract
Non-epithelial prostatic neoplasms are infrequent and cover a broad array of entities that include both benign and highly aggressive tumours. Because they are very infrequent, there is often limited understanding of them, and the recognition of these entities, when encountered, may pose a diagnostic challenge, owing to histological overlap between them or their rarity. Most lesions in this category are mesenchymal in origin, such as prostatic stromal tumours arising from specialized prostatic stroma, smooth muscle tumours, both benign and malignant, and solitary fibrous tumours. Less commonly occurring tumours include neural, germ cell and melanocytic tumours that may be derived from cells not normally present in the prostate. Some tumours have well-established extraprostatic counterparts and, when encountered, are more commonly extraprostatic/secondary in origin; these include gastrointestinal stromal tumours and most haematopoietic tumours. The majority of tumours are characterized by a spindle cell pattern with significant overlap in morphological features. In this setting, appropriate use of immunohistochemistry and molecular studies are often necessary for accurate diagnosis, prognosis, or prediction for therapy. This review addresses and updates the clinicopathological features of the entire spectrum of non-epithelial tumours with an approach to the histological diagnosis.

Abstract
Primary seminoma of the prostate is extremely rare. We describe a case of a 35-year-old man who presented with difficulty in urinating. Physical findings were unremarkable, but a rectal examination revealed a slightly hardened prostate with a nodule in the right lobe. Blood parameters were normal; however, blood chemistry revealed slightly elevated lactic dehydrogenase, and microscopic hematuria was evident. Serum prostate acid phosphate, carcinoembryonic antigen, and alpha-fetoprotein values were within normal limits. Both computed tomography and magnetic resonance images revealed a large mass in the prostate gland. A prostatic sarcoma or malignant lymphoma was initially suspected. A systemic survey using 18-fluoro-2-deoxyglucose (F-18 FDG) positron emission tomography revealed focal FDG uptake in the prostate gland. A prostatic biopsy of the mass was histologically diagnosed to reveal an extragonadal seminoma.

Abstract
Extragonadal yolk sac tumors (YSTs; primary and metastatic) are rare but are malignant germ cell tumors. Pathologic diagnosis of extragonadal YSTs can be challenging without immunohistochemical markers but markers used for diagnosing these tumors such as placental-like alkaline phosphatase (PLAP), alpha-fetoprotein (AFP), and glypican-3 lack adequate sensitivity and/or specificity. In earlier studies with gonadal germ cell tumors, SALL4 has been identified as a novel diagnostic marker for YSTs and other types of primitive germ cell tumors. Here, we investigated the diagnostic utility of SALL4 in 59 extragonadal YSTs (27 primary sacrococcygeal, 15 primary nonsacrococcygeal, and 17 metastatic) by immunohistochemical staining. We also compared SALL4 with PLAP, AFP, and glypican-3. In addition, we performed immunostains for pancytokeratin, epithelial membrane antigen, and OCT4 in these tumors. Our results showed that all 59 YSTs showed strong pancytokeratin staining (70% tumor cells in 1 case, >90% tumor cells in 58) and 10 (17%) of them also showed focal epithelial membrane antigen staining (<3% tumor cells). All 59 YSTs were negative for OCT4. Strong SALL4 staining was seen in all 59 YSTs (in more than 90% tumor cells in 54 and 70% to 85% tumor cells in 5 YSTs). Only 39 of 59 (66%) YSTs showed positive PLAP staining and the staining was often focal (in less than 30% tumor cells) (28 of 39 cases). Positive AFP staining was seen in the vast majority of YSTs (56 of 59 or 95%); however, 32 (54%) YSTs showed staining in less than 30% tumor cells. Although all 59 YSTs showed positive glypican-3 staining, 18 (30%) showed staining in less than 30% tumor cells, and additional 10 (17%) showed staining in between 30% and 60% tumor cells. In these 59 YSTs, the mean percentage of tumor cells stained with PLAP was 14% (range: 0% to 90%), with AFP 35% (range 0% to 95%), and with glypican-3 57% (range: 1% to 100%), whereas the mean percentage of tumor cells stained for SALL4 was 94% (range: 70% to 100%) (P<0.001). Our results indicate that SALL4 is a novel sensitive (100% sensitivity) diagnostic marker for extragonadal YSTs. SALL4 is a more sensitive marker than PLAP, AFP, or glypican-3 for extragonadal YSTs.

Abstract
Abstract A 54-year-old gentleman was suspected of having sarcoma of the prostate because of his low serum prostate-specific antigen level (1.9 ng/mL) and an enlarged heterogeneous mass on computed tomography and magnetic resonance imaging scans. Pathological examination of the prostate needle biopsy indicated seminoma, which was confirmed with immunohistochemical staining. There was no evidence of disease in other areas on physical examination or on radiographic tests. Therefore, we diagnosed the case as a primary seminoma of the prostate, which was consequently treated with a total of three courses of bleomycin, etoposide and cisplatin chemotherapy. Complete response was obtained on computed tomography, magnetic resonance imaging and prostate needle re-biopsy. To our knowledge, there have only been five cases of primary seminoma of the prostate reported.

Abstract
A 42-year-old man presented with severe abdominal pain, constipation, and hematuria. The patient had a history of seminoma treated by chemotherapy followed by bilateral orchiectomy and retroperitoneal lymph node dissection 16 years earlier. A computed tomography (CT) scan showed a 8.0 x 6.0 x 5.0 cm mass in the retrovesical space, encompassing the left side of his proximal bladder, the prostate, and the rectum. A urine cytologic specimen showed loosely cohesive cell clusters composed of highly atypical large cells and occasional large, single cells with macronucleoli present in a background of mainly lymphocytes and histiocytes was diagnosed as recurrent seminoma. Prostate biopsies showed extensively necrotic seminoma with accompanying granulomatous reaction. The tumor cells were immunoreactive for c-kit (CD117), placental-like alkaline phosphatase (PLAP), D2-40, and OCT4. To our knowledge, this is the second report on urine cytology of metastatic seminoma.
