Testis. Orchiectomy specimen showing testis replaced by tumour (proven to be seminoma ). (WC/Ed Uthman) The testis, plural testes, are important for survival of the species. Tumours occasionally arise in 'em. They generally are not biopsied. If the testis is biopsied, it is usually for fertility Appendix testis. It consists of columnar epithelium enclosing a highly vascular fibrous core with smooth muscle cells. Invaginations of the surface may result in appearance of glandular structures in the core, as seen here. Due to its pedunculated structure, it may undergo hemorrhagic infarction causing severe testicular pain Focally, fibrosis is seen without definite tumour outlines. There is no significant inflammation. The rete testis is identified. Rare seminiferous tubules have spermatid within. The germ cells seen do not have appreciable nuclear atypia. Small Leydig cell clusters are seen in some sections. See also. Testis. Pick's adenoma (Sertoli cell nodule. A decline in testicular function occurs normally with the aging process, matched by involutional changes in the testicular parenchyma, including hypospermatogenesis, peritubular fibrosis, and hyalinization of tubules commonly resulting in a pattern resembling that of mixed primary testicular pathology

Appendix testis (T) is a small round or oval, sessile or pedunculated structure attached to the tunica albuginea on the antero-superior portion of the testis. It is a remnant of the cranial portion of the m llerian duct. Appendix epididymis (E) is a remnant of the cranial portion of the mesonephric duct. It is located just above the appendix.

Seminoma is the most common pure germ cell tumor (GCT) of the testis, accounting for up to 50% of cases.

Materials and Methods: All testicular biopsies from males with infertility received by the Pathology Department of King AbdulAziz University Hospital, Jeddah, in the period from January 2004 until May 2010 are reviewed and histopathologically classified into seven categories as follows : Normal spermatogenesis, hypospermatogenesis, germ cell maturation arrest (GCMA), Sertoli cell only syndrome. Cryptorchid Testis: Aggregates of small seminiferous tubules lined by immature-appearing Sertoli cells are commonly found in cryptorchid testes. They are usually microscopic but sometimes may be large enough to be detected clinically or on testicular ultrasound. Leydig Cell Tumor (LCT): Features favoring LCT include: diffuse sheet-like growth. In this series testicular nubbins in vanishing testes contained no viable testicular tissue. Since the risk of testicular cancer in an undescended testis is 8 to 10% and the incidence of viable testicular tissue in these nubbins ranges from 0% in our series to 11% in others, there is only a 0 to 1.1% risk of testicular cancer in the nubbin Sperm Granuloma.

About half the time when infertility occurs in couples wanting children, the cause is a problem in the male genital system The two main categories of testicular tumors are germ cell tumors (GCTs), which account for 95 percent of cases, and sex cord-stromal tumors.

Types of Testicular Cancer. The most common type of testis cancer is a germ cell tumor. There are two main types of GCT: seminoma and nonseminomatous germ cell tumors (NSGCT). Both seminoma and NSGCT occur at about the same rate, and men can have seminoma, NSGCT or a combination of both. There are several differences between seminomas and NSGCT. Abstract. Approximately 94-96 % of testicular tumors are of germ cell origin. The remaining tumors are either sex cord tumors or lymphomas. The germ cell tumors are rare (approximately 1 % of all tumors in men). They are classified histologically into seminomas and non-seminomas. More than 50 % of germ cell tumors consist of more than one.

Testes pathology. 1. TESTES PATHOLOGY. NIRAV HITESH KUMAR VALAND. 2. Anatomy of the testes. • The testes (testicles) are the male gonads, paired ovoid reproductive glands that produce sperms (spermatozoa) and male hormones, primarily testosterone. • The testes are suspended in the scrotum by the spermatic cords, with the left testis usually. Performing a testicular biopsy does not have a high complication rate: sometimes bleeding and infection occur. Biopsies taken in small atrophic testicles might increase the risk of hypogonadism, which then results in life-long testosterone substitution. 10 This concern should be considered in advance and discussed with the patient.

Testis. The pair of testes produces spermatozoa and androgens. Several accessory glands produce the fluid constituents of semen. Long ducts store the sperm and transport them to the penis. The male reproductive system consists of paired testes and genital ducts, accessory sex glands and the penis. The testes and ducts are shown in this diagram Context.—Although relatively rare, testicular cancer is the most common solid organ malignancy in young men and remains a leading cause of cancer death in this population.Different types of testicular tumors are treated differently, with an overall very high cure rate with proper management. Pathologists must, therefore, be familiar with important diagnostic pitfalls in testicular pathology.

Topics discussed in this compilation include the roles an Orchitis, inflammation and swelling of the testes as a result of infection or physical injury. The testes are a pair of organs located in the scrotum of the male; they produce sperm cells for reproduction.

Spermatogenesis, the origin and development of the sperm cells within the male reproductive organs, the testes.The testes are composed of numerous thin tightly coiled tubules known as the seminiferous tubules; the sperm cells are produced within the walls of the tubules.
