Primary carcinoid tumour of the testis is extremely rare. We describe a case of testicular carcinoid, discuss the ultrasound appearances and differential diagnosis.

Testicular fibroma of gonadal stromal origin is a rare benign tumor of testis which usually presents as a slow growing testicular mass. Only 25 cases of testicular fibroma have been reported in the literature. Presence of minor sex cord elements in this tumor is even rarer. We report a case of testicular fibroma with minor sex cord elements that involved almost the entire testis and tunica vagi...

A rare case of a seminoma developing in an atrophic testis is described and the role of testicular atrophy in tumorigenesis is discussed.

OBJECTIVE Ultrasound surveillance of patients with testicular microlithiasis (TM) has been recommended because of the reported association between TM and testicular cancer (TC). The purpose of this review is to summarize what is known about TM and discuss recent recommendations. CONCLUSION The most recent recommendations do not support the use of routine ultrasound surveillance for patients w...

Plasma cell neoplasms include various conditions ranging from indolent such as monoclonal gammopathy of undetermined significance (MGUS) to more aggressive forms multiple myeloma (MM). The World Health Organization classifies plasmacytomas into two types: solitary osseous plasmacytoma (SOP) and extramedullary (EMP). Most primary EMPs occur in the upper gastrointestinal tract, head neck, respira...

BACKGROUND GOLPH2 (Golgi phosphoprotein 2) is a novel Golgi membrane protein. Despite its unknown physiologic function, however, it has been proposed as a biomarker for hepatocellular and prostate carcinoma due to its upregulation in those cancer entities. Whether the overexpression of GOLPH2 is tumour specific or a generic parameter of malignancy and whether this finding is true for additional...

Sonography is the imaging modality of choice for the scrotum because it is simple, relatively inexpensive, and quick. Recent technological advances and transducer improvements have led to exquisite high-resolution detail in gray-scale as well as Doppler imaging. The purposes of this pictorial essay are to review the anatomy and embryology of the scrotal contents and to review the various scrota...

Sera from eleven patients with gonadal germ cell tumors were tested for alpha-fetoprotein (AFP) by counterelectrophoresis. Ovarian neoplasms containing either the endodermal sinus tumor (EST) or dysgerminoma and half of the testicular embryonal carcinomas elaborated the protein into the serum. The presence of AFP in the serum seemed to correlate with early metastasis or a fatal outcome. That th...

BACKGROUND Testicular tumors are the most common genital neoplasms in male dogs, with Leydig cell tumors (LCT), seminomas (SEM), and Sertoli cell tumors (SCT) the most common forms. Human SEM are classified as classical (CSEM) or spermatocytic (SSEM). Intratubular germ cell neoplasia of undifferentiated origin (IGCNU) is another form of human testicular tumor. The aim of this study was to verif...
