Sertoli cell nodule, abbreviated SCN, is a benign lesion of the testis that is usually incidental. It is also known as Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis Sertoli-cell-only syndrome (also referred to as germ cell aplasia) applies to a testicle in which germ cells at any stage of maturation are absent, but the tubular architecture is not effaced by fibrosis and supporting cells continue to be present. The picture superficially resembles the prepubertal testis (Figure 2) Sertoli cell tumour is a sex cord-stromal tumour typically found in the testis. It is occasionally seen in women
Sertoli cell-only syndrome (a.k.a. Del Castillo syndrome and germ cell aplasia) is a disorder characterized by male sterility without sexual abnormality. It describes a condition of the testes in which only Sertoli cells line is present in seminiferous tubules Sertoli cell-only syndrome (SCOS) also known as germ cell aplasia is characterized by azoospermia in which the seminiferous tubules of testicular biopsy are lined only with Sertoli cells. The definitive diagnosis of SCOS is by diagnostic testicular biopsy Sertoli cell only syndrome 16 30.18 Seminiferous tubule hyalinization 04 7.54 Mixed pattern 05 9.43 Discordant pattern 01 1.88 Table 2: Mixed histopathological patterns in the same testicular biopsy (n=05) Mixed Histopathological patterns No. of cases Sertoli cell only syndrome - Germ cell maturation arrest 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.
Leydig cells are usually normal in appearance but may appear to be increased in number due to reduced tubular diameter. Causes of Sertoli cell-only syndrome include: gonadotropin deficiency, cryptorchidism, viral orchitis, irradiation, alkylating agents, hormonal therapy for prostate cancer etc. slide 4 of 1 . In Klinefeher's syndrome, testicular alteration has been attributed to the presence of an extra X chromosome,z7 Fhroland and Skakkebaek'a have distinguished two types of Sertoli-cell. The following histologic subtypes are seen: adult granulosa cell tumor, juvenile granulosa cell tumor, Sertoli-Leydig cell tumor, sex cord tumor with annular tubules, and mixed forms, including gynandroblastoma. Figure 1 shows representative pathology images from juvenile granulosa cell tumor, Sertoli-Leydig cell tumors, and gynandroblastoma Sertoli cell-only syndrome (SCOS) also known as germ cell aplasia is characterized by azoospermia in which the seminiferous tubules of testicular biopsy are lined only with Sertoli cells No. 4 TESTICULAR & OVARIAN ANDROBLASTOMA & SERTOLI CELL TUMORY reilurn 773 man, a slight degree of gynecomastia and a nut-sized swelling of the left testis were ob- served at the age of 52.

The term Sertoli-cell--only syndrome should be reserved for those cases in which all the tubules in the biopsy show absence of germ cells; if some tubules contain only Sertoli cells but other tubules contain advanced spermatids, the overall diagnosis is hypospermatogenesis with a mixed pattern . When positive in the non-Sertoli cell tumors, the extent of expression tended to be focal to patchy (50% or less positive cells). In Sertoli cell tumors, inhibin and calretinin were expressed in 96% and 54% of cases, respectively Leydig cells were hyperplastic. The prepubertal patients showed only diffuse lesions characterized by Sertoli cell hyperplasia, decreased germ cell numbers, and a discontinuous immunoreaction to collagen IV Sertoli cells. Germinal epithelium of the testicle. Histological section through testicular parenchyma of a boar. A Sertoli cell (a kind of sustentacular cell) is a 'nurse' cell of the testes which is part of a seminiferous tubule. It is activated by follicle-stimulating hormone, and has FSH-receptor on its membranes The Sertoli cell only syndrome and the seminiferous tubule hyalinization categories were each reported in 16 cases (16%). Nine cases (9%) showed a mixed pattern. Discordant pattern was seen in 5 (5%) cases.<br>Conclusion: Our study showed that hypospermatogenesis is the commonest pattern in testicular biopsies taken from males with.
Welcome to the updated version of Pathology for Urologists! This program was designed to help Urology residents and fellows familiarize themselves with the pathologic features of common urologic entities. This will serve not only as a resource tool for your review but also as a quick reference guide to urologic pathology cal alterations that might occur in the structure of the ipsilateral testis after experimental varicocele, to determine whether this effect was time dependent, and to evaluate the possible role of l-carnitine on the varicocele. Materials and methods Thirty-six young adult albino rats were used. They were equally divided into three groups. Group 1 was the control. Group 2 was the experimentally. Sertoli cell only syndrome on right and Germ cell maturation arrest on left side.

During postnatal life, Sertoli cells undergo extensive proliferative activity, which is essential for the expansion of the testis cords and to produce the final number of Sertoli cells in adulthood (Figure 14.1A and B) (reviewed in ).Because each Sertoli cell supports a fixed number of germ cells, the number of adult Sertoli cells quantitatively determines sperm output, with decreases and. Sertoli cell-only syndrome (SCOS) affects about 26.3-57.8% of azoospermic men, with their seminiferous tubules containing only Sertoli cells. Recently, it was reported that testicular biopsies from nonobstructive azoospermic (NOA) patients contained germ cells, and that sperm could be found in the tubules of 20% of SCOS patients using testicular sperm extraction technology Outline the epidemiology of infertility in the United States. pathology of the hypothalamus, pituitary, adrenals, or gonads can quickly lead to a hormone imbalance, malformation of the genitals, and/or infertility. Sertoli-cell only syndrome. TREATMENT OF INFERTILITY Biopsy diagnoses were as follows: Absent spermatogenesis in 19 cases (49%), of which six (32%) were due to Sertoli-cell-only syndrome, 10 cases (29%) due to maturation arrest, hypospermatogenesis in four cases (11%), and complete spermatogenesis in six cases (15%) In addition, a strong association exists between intratubular Sertoli cell proliferations and the Puetz-Jeghers syndrome. 2 Whether intratubular Sertoli cell proliferations represent a non-neoplastic, proliferative phenomenon or an intraepithelial stage in the evolution of certain Sertoli cell tumours is still controversial. 2 Although the.
Sertoli cell-only syndrome is the condition wherein sperm-manufacturing cells are absent. Treatment for elevated or low FSH levels depends upon the cause of abnormal FSH levels. A simple blood test helps measure FSH levels. FSH level above 15 mIU/ml in a man is considered as very high. Low FSH levels usually indicate improper development or.

The two main categories of testicular tumors are germ cell tumors (GCTs), which account for 95 percent of cases, and sex cord-stromal tumors. Testicular pathology is a nosologically complex subject because of the spectrum of histologic subtypes and variable clinical behavior, particularly among GCTs. Prediction of biologic behavior depends upon.
Peutz-Jeghers syndrome (PJS), in most cases, is attributed to mutation in STK11/LKB1 and is clinically characterized by. We selected Sertoli cell-only and maturation arrest cases for two reasons: these two pathologies have clear histological characteristics and a high frequency of Yq microdeletions in Sertoli cell-only syndrome has been reported in prospective studies (Foresta et al., 1998; Ferlin et al., 1999) In humans, pure or total Sertoli cell-only syndrome is characterized by azoospermia and a complete lack of germ cells, whereas the mixed form reveals focal Sertoli cell-only areas adjacent to. Immunohistochemistry studies in case of Sertoli cell-only syndrome with immature Sertoli cells (n =1) showed expression of inhibin B bodies: these are gran-ules in apical region of the cells (+2). In Leydig cells (+2) as well as in germ cells (+2), a marked inhibin B expression can also be detected. In case of Sertoli cell Sertoli cell only syndrome is a common finding of non-obstructive azoospermia. It is a histopathologic phenotype of spermatogenic failure described first by Del Castillo et al. . In complete germ cell aplasia, the tubules are reduced in diameter, contain only Sertoli cells and no germ cells are present

Sertoli cell function. Sertoli cells have extensive cytoplasm which spans the full height of the seminiferous epithelium from basement membrane to lumen (Figure 21.2).Where adjacent Sertoli cells come into contact with each other near the basement membrane, special occluding junctions are formed which divide the seminiferous epithelium into a basal (outer) compartment, which interacts with the.

Treatment plans are generally limited to a short interval. According to both Johnsen' and McLachlan' scoring systems of germinal histological classification, testis parenchyma of negative sperm retrieval iNOA men were classified as Sertoli cells only.
The testes may exhibit at least four distinct features: Sertoli cell-only tubules, Leydig cell hyperplasia, nodular Sertoli cell masses, and germ cell atypia and neoplasia ( Figs. 1.11 to 1.13 ). The background pattern consists of Sertoli tubules devoid of spermatogonia, admixed with abundant Leydig cells (see Fig. 1.12A and B ) Aims and outlines of the thesis Chapter 3 31 Pathobiological implications of the expression of markers of testicular carcinoma in situ by fetal germ cells.

IHC stain with Inh-A (inhibin-A) helps to differentiate from germ cell tumors but not from Sertoli cell tumors. Calretinin is a positive marker for LCT while WT-1 for SCT. SALL4, which is a newer marker, is negative in LCT and positive in GCTs. NKX3.1 is expressed routinely in Sertoli cells and P501S in Leydig cells and rete testis epithelium cells , because of fear of trauma to the testes with hematoma formation by the procedure and because cytology was unable to give information about the tubular basement membrane and status of interstitial tissue.11 But later on many studies carried out showed that FNAC evaluated spermatogenesis of entire testes
Bilateral ISCPs were the only pathologic finding in three patients (patient nos. 1-3) and were associated with a microscopic tumor that resembled a large-cell calcifying Sertoli cell tumor (LCCSCT) in a fourth patient (patient no. 4) Etv5 is expressed not only in the germline but also in Sertoli cells. Mice with a targeted Etv5 deletion undergo the first wave of spermatogenesis, but they subsequently show progressive germ cell depletion and a Sertoli cell-only syndrome (Chen et al., 2005) We have studied gonadal tissue from 10 individuals, 0.3-17 years of age, with a male phenotype and either hypospadias and/or cryptorchidism. Four patients, 0.3-15 years of age, had carcinoma in situ, 1 boy had Sertoli-cell-only pattern and the remainder prepubertal histology. Gonadoblastoma or invasive carcinoma was not found The Sertoli cells only prolificate after the completion of one year and therefore become an equal to the follicular cells that exist within women. On the other hand, the Leydig cells only start to prolificate once the 7 th week starts during the time of the second trimester No previous diagnostic biopsy has been (four patients without diagnostic testicle biopsy) or of foci of obtained in 10% of the patients, the remaining presenting complete spermatogenesis (,2% of tubules) in diagnostic Sertoli cell only (SCO) syndrome (48%) or maturation arrest testicle biopsy (seven patients with maturation arrest at the at the.
