Testicular melanotic neuroectodermal tumor of infancy (MNTI) is extremely rare, with 2 cases reported in the literature. Its rarity and rapid and infiltrative growth pattern pose a diagnostic challenge. A previously healthy 3-month-old male, presented with a history of worsening left hemiscrotal swelling for 1 week. An outside ultrasound was suggestive of testicular torsion. Left orchiectomy demonstrated a mass occupying almost entire testicle with a variegated cut surface, with areas of pigmentation, necrosis, and hemorrhage...

Malignant feminizing adrenocortical tumors are exceedingly rare. Their main presentation is gynecomastia. In these estrogen secreting tumors (with or without other adrenocortical hormones) lack of gynecomastia is exceptional as in our case. A 44-year-old man presented with abdominal pain. Radiological assessment revealed a tumor measuring 120 × 95 mm in the retroperitoneal area with numerous metastases. Pathological examination pleaded for an adrenal origin with a Weiss's score of 5. Six months later, the tumor relapsed, and he had a second surgery and was sent for hormone assessment...

Familial risks of breast cancer (BC) are well established but whether BC clusters with other, i.e. discordant, cancers is less certain but of interest for the identification of common genetic and possible environmental factors contributing to a general cancer susceptibility. We apply a novel approach to search for familial associations of BC with other (discordant) cancers based on the Swedish Family-Cancer Database. Relative risks (RRs) were calculated for BC in families with increasing numbers of patients with discordant cancer X, and conversely, familial RRs for cancer X in families with increasing numbers of BC patients...

Seminoma is the most common testicular malignant germ cell tumor which severely threaten male reproductive health. However, the pathogenesis and progression mechanisms are still unclear and little research is carried out to uncover the mechanism of this cancer. To identify gene signatures that are expected to converge on particular molecular pathways may drive the development of the core cancer characteristics in seminoma. We downloaded the gene expression profiles GSE18155 from GEO database and obtained the differentially expressed genes (DEGs)...

Malignant mesothelioma involving the para-testicular tunica is extremely rare and an aggressive tumor. Bilateral malignant mesothelioma of the tunica vaginalis is not reported previously in the literature. Rarity of the disease, absence of any specific clinical and radiological findings makes the preoperative diagnosis difficult. Aggressive surgical approach is the key to successful management with high inguinal orchiectomy and scrotectomy appears to be optimal treatment in patients with localized disease.

PURPOSE: To demonstrate the safety of surveillance of small testicular masses incidentally discovered during evaluation of male infertility. MATERIALS & METHODS: Retrospective review of a prospectively-collected database to identify male infertility patients found to have incidental small testicular masses (hypoechoic lesions <10mm) on scrotal ultrasonography. Men were offered close surveillance with interval imaging and office follow-up. Patient and imaging characteristics were collected for comparisons between surveillance and surgical groups with additional comparisons between benign and malignant pathologies to elucidate predictors of underlying malignancy...

Microcystin-leucine arginine (MC-LR) causes testicular inflammation and hinders spermatogenesis. However, the molecular mechanisms underlying the immune responses to MC-LR in the testis have not been elucidated in detail. In this study, we show that MC-LR induced immune responses in Sertoli cells (SC), germ cells (GC), and Leydig cells (LC) via activating phosphatidylinositol 3-kinase (PI3K)/AKT/nuclear factor kappa B (NF-κB), resulting in the production of pro-inflammatory cytokines and chemokines including tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and chemokine (C-X-C motif) ligand 10 (CXCL10)...

This study aimed to investigate the effects of anti-tumor necrosis factor (TNF)-α antibody (Ab) on alteration of penile structure in the hyperprolactinemia (hyperPRL) rat model. HyperPRL was induced in 8-week-old male Sprague-Dawley rats by allografting anterior pituitary (AP) glands under the renal capsule (+AP rats). Rats implanted with cerebral cortex (CX) were used as sham control (+CX rats). At 6 weeks post implantation, rats received either a single intra-testicular dose of TNF-α Ab (12.5 μg/kg) or testosterone replacement (2 doses of testosterone enanthate [TE], 3 mg/kg), and they were sacrificed 1 week later...

Serous borderline tumor (SBT) of the testis is a rare, ovarian epithelial-type tumor of the testis. We present a case of SBT after radical orchiectomy in a 59-year-old man who had 3-month progressive enlargement of his right hemi-scrotum, negative testicular tumor markers and scrotal ultrasound equivocal for malignancy. Magnetic resonance imaging (MRI) of the pelvis was obtained to aid with evaluation and showed marked hyperintensity on T2-weighted images with frond-like nodular peripheral enhancement within right testis mass...

The interaction between obesity and chronic inflammation has been studied. Diet-induced obesity or chronic inflammation could reduce the testicular functions of males. However, the mechanism underlying the reproductive effects of fattening foods in males with or without chronic inflammation still needs further discussion. This study was aimed to investigate the effects of high-fat, high-protein diet on testicular steroidogenesis and sperm parameters in adult mice under physiological and chronic inflammatory conditions...

Primary signet ring stromal tumor of the testis (PSRSTT) is an extremely rare tumor described only twice in the literature. Pancreatic-analogue solid pseudopapillary neoplasm (SPN) of the testis is a recently reported entity with morphological overlap with PSRSTT. We reviewed our files to find all cases of PSRSTT in order to better characterize this entity. We studied 13 cases of PSRSTTs using histological, immunohistochemical (IHC) and molecular genetic methods and compared the results with pancreatic SPN...

Chronic orchialgia is a vexing condition defined as chronic or intermittent scrotal pain lasting at least three months that significantly interferes with daily activities. There are currently no guidelines regarding the diagnosis and management of this condition despite it being the cause of 2.5-4.8% of urologic clinic visits. Men often present with chronic orchialgia in their mid to late 30s, although the condition can present at any age. A broad differential diagnosis of chronic orchialgia includes epididymitis, testicular torsion, tumors, obstruction, varicocele, epididymal cysts, hydrocele, iatrogenic injury following vasectomy or hernia repair, and referred pain from a variety of sources including mid-ureteral stone, indirect inguinal hernia, aortic or common iliac artery aneurysms, lower back disorders, interstitial cystitis, and nerve entrapment due to perineural fibrosis; approximately 25-50% of chronic orchialgia is idiopathic in nature...

Prophylactic gonadectomy in young adult women with complete androgen insensitivity syndrome (CAIS) to avoid development of an invasive testicular germ cell tumor (TGCT) is currently advised in most centers. However, women with CAIS increasingly question the need of this procedure. In order to provide optimal counseling and follow-up of these women, insight in the mechanisms underlying TGCT development in androgen insensitivity syndrome (AIS), data regarding the incidence of TGCT in AIS adults specifically, and an overview of existing and novel screening tools for in situ and invasive neoplastic lesions are crucial...

The staging of testicular nonseminomatous germ cell tumors (NSGCTs) with lymphovascular invasion (LVI) of the spermatic cord in the absence of cord parenchymal involvement remains controversial. Our previous study showed that tumors with spermatic cord LVI present at a higher clinical stage than tumors with LVI confined to the testis (pT2). We compared NSGCTs with LVI of the spermatic cord without direct involvement of the spermatic cord soft tissues to pT3 tumors to help clarify the appropriate staging of this histologic finding...

INTRODUCTION: Pure choriocarcinoma of the testes is a rare, aggressive germ cell tumor (GCT) that can metastasize to the brain. Although its prognosis has improved with the development of cisplatin-based chemotherapy regimens, cerebral metastases are prone to hemorrhage and are associated with high morbidity. Here, we present two cases of testicular choriocarcinoma with cerebral metastasis and discuss potential pitfalls in their diagnosis and management. We also review cases in the literature that feature these rare lesions...

Leydig cell tumors (LCTs) are rare testicular tumors. Incidence is 1%-3% of all testicular neoplasms, bilateral in 10%. They are frequently hormonally active, leading to feminizing or virilizing syndromes. LCTs can be either pure or mixed with germ cell tumors or other sex cord-stromal tumors. Here, we are reporting a benign pure LCT in a 6-year-old boy presented with pseudopuberty.
