RATIONALE: Testicular Leydig cell tumor (LCT) is a rare neoplasm. It commonly presents as a painless testicular mass with or without endocrine changes. Histological and immunohistochemical examination play important roles in differentiating LCT from testicular germ cell tumors. PATIENT CONCERNS: We highlight the imaging phenotype, as well as the pathological findings of a case of LCT in a 62-year-old male. DIAGNOSES: Preoperative noncontrast CT scan of the abdomen revealed a 7...

Norimitsu Shirai, Mark G Evans
The present article describes an occurrence of testicular microlithiasis in a cynomolgus monkey from a routine regulatory toxicology study. The monkey was from a negative control group. Microscopically, the lesion was characterized by multiple extracellular mineralized calculi within seminiferous tubular epithelia of both testes without any tissue reaction or abnormal condition such as cryptorchidism, testicular neoplasm, or hypogonadism. The present case is remarkable in that there is a paucity of reports on spontaneous testicular microlithiasis in nonhuman primates...

PURPOSE: To analyze the dimensional characteristics between non-palpable testicular masses detected during ultrasonographic (US) study and their postoperative dimensions reported in definitive histological diagnosis, and evaluate if the sonographic measurements may be a relevant parameter to improve the identification of testicular lesions amenable to treatment with testicular-sparing surgery (TSS). METHODS: A total of 77 patients who underwent radical orchiectomy or TSS for non-palpable testicular masses suspected for malignant neoplasms were included into this study...

REVIEW
Vincent Murray, Jon K Chen, Long H Chung
The cancer chemotherapeutic drug, bleomycin, is clinically used to treat several neoplasms including testicular and ovarian cancers. Bleomycin is a metallo-glycopeptide antibiotic that requires a transition metal ion, usually Fe(II), for activity. In this review, the properties of bleomycin are examined, especially the interaction of bleomycin with DNA. A Fe(II)-bleomycin complex is capable of DNA cleavage and this process is thought to be the major determinant for the cytotoxicity of bleomycin. The DNA sequence specificity of bleomycin cleavage is found to at 5′-GT* and 5′-GC* dinucleotides (where * indicates the cleaved nucleotide)...

CD20-negative diffuse large B-cell lymphoma (DLBCL) is a very uncommon neoplasm, and very rare unclassifiable cases that did not meet the criteria for well-established subtypes of CD20-negative DLBCLs have been reported. CD20-negative DLBCLs often present an aggressive clinical course with important chemoresistance and poor prognosis. Here, we report a case of CD20-negative DLBCL presented as a testicular mass. To the best of our knowledge, this is one of the first reported cases of testicular unclassifiable CD20-negative DLBCL...

BACKGROUND: Recently, we came with the theory of a possible relationship between a group of testicular and pancreatic tumors. We used one case of a pancreatic analogue solid pseudopapillary neoplasm of the testis composed partially of areas reminiscent of solid pseudopapillary neoplasm (SPN) of the pancreas and partially of structures identical to primary signet ring stromal tumor of the testis (PSRSTT) as a connecting link between these two entities. After demonstrating that PSRSTT and pancreatic analogue SPN of the testis share the same immunoprofile and genetic features characteristic for pancreatic SPN, we came to the conclusion that pancreatic analogue SPN of the testis and PSRSTT represent a morphological spectrum of a single entity and that both are related to the pancreatic SPN...

Testicular germ cell tumours (TGCTs) are a heterogeneous group of neoplasms, mostly affecting young men. Curability rates are high and adequate treatment relies on careful and accurate pathological and clinical assessment. Indeed, TGCTs' histopathological subtyping is critical for adequate therapeutic decision. Considering the limitation of currently available serum biomarkers, novel candidates have been proposed, most notably miR-371a-3p, which outperformed classical serum markers, but no detailed information concerning TGCT subtype was available...

Testicular cancer is the most common solid tumor among males 15 to 34 years of age, with an estimated 8,850 new cases and 410 deaths during 2017 in the United States. With effective treatment, the overall five-year survival rate is 97%. Risk factors for testicular cancer include undescended testis (cryptorchidism), personal or family history of testicular cancer, age, ethnicity, and infertility. The U.S. Preventive Services Task Force recommends against routine screening in asymptomatic men. Men with symptoms should receive a complete history and physical examination...

Leydig cell tumor is a rare sex cord tumor that accounts for 1-3% of all testicular neoplasms. Seminomas are more common and occur in 30-40% of testicular tumors. Leydig cell tumors are derived from undifferentiated gonadal mesenchyme and the concurrent development of the tumor and a seminoma which are derived from germinal epithelium in an ipsilateral testis is extremely rare. Here we report a case of ipsilateral Leydig cell tumor and seminoma occurring in a 38-year-old man with a left testicular mass. The key to diagnosis is dependent on histopathology and immunohistochemistry...

Testicular cancer has become the paradigm of adult-onset cancer survivorship, due to the young age at diagnosis and 10-year relative survival of 95%. This clinical review presents the current status of various treatment-related complications experienced by long-term testicular cancer survivors (TCS) free of disease for 5 or more years after primary treatment. Cardiovascular disease and second malignant neoplasms represent the most common potentially life-threatening late effects. Other long-term adverse outcomes include neuro- and ototoxicity, pulmonary complications, nephrotoxicity, hypogonadism, infertility, and avascular necrosis...

Metronidazole is a synthetic derivative of nitroimidazole that has been widely used for the treatment of several bacterial and protozoal parasitic infections including trichomoniasis, amoebiasis, giardiasis, liver abscess, acute ulcerative gingivitis, syphilis and tropical phagedena. In addition to its toxicity in the gastrointestinal tract and central/peripheral nervous system, metronidazole has been reported to cause mucosal imbalance by affecting the expression of mucin (Muc2 gene), which is responsible to form an insoluble mucous barrier that protects the gut lumen from microbial colonization...

High-dose chemotherapy combined with autologous hematopoietic stem-cell transplantation (ASCT) is the first-line treatment for multiple myeloma. Yet, some patients will relapse. Testicular plasmacytoma which rarely happens can be isolated or associated with progressive multiple myeloma. Here, we report a case of multiple myeloma (MM) undergoing ASCT when the patient obtained complete remission. He developed painless right testicular swelling after nearly 3 years since the ASCT. After radical orchiectomy, histopathology showed diffuse abnormal plasma cells infiltration of the testicular tissue...

Seminomas are the most frequent testicular tumors and in spite of specific markers some histological subtypes can be diagnostically challenging due to the potential overlap of morphologic features and a variant antigen expression. Terminal deoxynucleotidyl transferase (TdT) is a DNA polymerase present in hematogones, thymic T cells, lymphoblastic lymphoma/leukemia (LBL), and in some cases of acute myeloid leukemia but so far has not been described to be expressed in seminomas. After observing a reactivity of TdT in one case of seminoma, we analyzed ten additional tumors by immunohistochemistry to determine their spectrum of reactivity for TdT...

A 44-year-old man presented with cerebellar ataxia and limbic encephalitis and was ultimately diagnosed with metastatic germ cell neoplasm resulting from a "burned out" primary testicular tumor. The patient had progressive ataxia, leading to a thorough investigation for infectious, autoimmune, metabolic, and malignant causes of acquired cerebellar ataxia that revealed no significant findings. Testicular sonography demonstrated a possible right testicular lesion that was not confirmed on radical inguinal orchiectomy...

Tumors with Müllerian-like serous or mucinous phenotypes originating in the testis and its adnexa are rare neoplasms that have been increasingly recognized in recent years. Cystadenomas with or without ovarian-type stroma, borderline tumors, and adenocarcinomas are the main documented types. Although a handful cases of putative endometrioid adenocarcinomas have been reported, to our knowledge no case of endometrial stromal-type neoplasm has ever been reported in the literature. A 59-year-old man presented with a 2 cm left intrascrotal mass that was found on sonographic examination to arise from the epididymal tail with prominent vascularization...

INTRODUCTION: The role of autoimmune responses against central nervous system (CNS) antigens in encephalitis presenting with non-classified neurologic or psychiatric symptoms has been appreciated in the past decade. Paraneoplastic limbic encephalitis has a poor prognosis and is most commonly associated with lung, ovarium, and testicular neoplasms, leading to immune reactions against intracellular antigens (anti-Hu/ANNA1, anti-Ri/ANNA2, anti-CV2/CRMP5 and anti-Ma2/Ta). In contrast, the recently described autoimmune encephalitis subtypes present with a broad spectrum of symptoms, respond to autoimmune therapies well and usually associate with autoantibodies against neuronal cell surface receptors (NMDAR, GABAB R, AMPAR) or synaptic proteins (LGI1, CASPR2)...

The Tumor-Node-Metastasis (TNM) classification on cancer staging, jointly developed by the American Joint Commission on Cancer (AJCC) and the Union for International Cancer Control (UICC), has been updated to its 8th edition with two contemporaneous versions published by the AJCC and UICC. While the goal of the AJCC and UICC is to have identical TNM staging systems, differences exist between these two publications including in the staging of urologic cancers. Among several new facets in the AJCC staging manual, a select few of greater import include an expanded section on imaging, presentation of levels of evidence for significant changes, and endorsement of risk assessment models that pass the AJCC quality criteria such as in prostate cancer...

Testicular germ-cell cancer (GCC) is a curable disease. Stage I patients are mostly cured by surgery alone. For those with good prognosis advanced disease, radiotherapy in some patients with stage II Seminoma and chemotherapy for all other patients, are responsible for 95% of long-term survivors. Unfortunately, despite this high level of curability, overall survival has been reported lower for those patients receiving either radiotherapy or chemotherapy versus patients treated by surgery alone. Long-term survivors face a higher incidence of second neoplasms, and a higher risk of cardiovascular disease and metabolic syndrome than expected...

Glomus tumor in the genital area is extremely rare, with an extensive search in the medical literature revealing only 1 case arising in the scrotum. They can be easily mistaken, both clinically and radiologically, for skin neoplasms or primary testicular tumors involving the scrotum. This report presents a case of a 54-year-old man who presented with a painful right scrotal swelling. Ultrasound suggested the possibility of an epidermal inclusion cyst. The excised mass was diagnosed as a benign glomus tumor...
