Abstract
Large cell calcifying Sertoli cell tumor (LCCST) is a rare testicular tumor, usually occurring in young men before the age of 20. Ultrastructural study has been performed rarely demonstrating Sertoli cell features. We report a case of LCCST in a 7-year-old boy. A well-circumscribed yellowish-tan, 1.5-cm-sized mass was located within the left testicular parenchyma. The cut surface was somewhat resilient with multiple calcifications. On microscopic examination, the tumor was composed of large eosinophilic polygonal cells with abundant eosinophilic cytoplasm arranging in solid tubular and trabecular patterns, superficially mimicking Leydig cell tumor. However, there were multiple calcifications and the tumor cell nests were surrounded by PAS-positive basement membrane. Ultrastructural examination revealed the features of the Sertoli cell with Spangaro's crystals. The right testis showed a normal appearance by ultrasonogram and there were no other clinical features associated with Carney syndrome.

Abstract
Primary cilia are sensory organelles that coordinate numerous cellular signalling pathways during development and adulthood. Defects in ciliary assembly or function lead to a series of developmental disorders and diseases commonly referred to as ciliopathies. Still, little is known about the formation and function of primary cilia in the mammalian testis. Here, we characterized primary cilia in adult human testis and report a constitutive expression of cilia in peritubular myoid cells and a dynamic expression of cilia in differentiating Leydig cells. Primary cilia are generally absent from cells of mature seminiferous epithelium, but present in Sertoli cell-only tubules in Klinefelter syndrome testis. Peritubular cells in atrophic testis produce overly long cilia. Furthermore cultures of growth-arrested immature mouse Leydig cells express primary cilia that are enriched in components of Hedgehog signalling, including Smoothened, Patched-1, and GLI2, which are involved in regulating Leydig cell differentiation. Stimulation of Hedgehog signalling increases the localization of Smoothened to the cilium, which is followed by transactivation of the Hedgehog target genes, Gli1 and Ptch1. Our findings provide new information on the spatiotemporal formation of primary cilia in the testis and show that primary cilia in immature Leydig cells mediate Hedgehog signalling.

Abstract
Ovarian Sertoli cell tumors are rare, and their morphologic spectrum, behavior, and factors influencing the latter are not clearly established. They may be mimicked by many different tumors, some of them more frequent than Sertoli cell tumors; immunohistochemistry may aid in this differential, but its role has not been analyzed in a large series. We studied the clinicopathologic features of 54 Sertoli cell tumors, including the immunohistochemical profile of 23 of them. The patients, 6 of whom had Peutz-Jeghers syndrome, ranged from 2 to 76 years of age (mean, 30 years). Eleven patients had estrogenic and 4 had androgenic manifestations. The tumors ranged from 0.8 to 30 cm, with the majority being in the range of 4 to 12 cm. They were all unilateral, usually solid, and often yellow. The predominant microscopic pattern was tubular, seen, albeit often only focally, in all tumors; other patterns were cords or trabeculae (28), diffuse (21), pseudopapillary (4), retiform (3), islands or alveolar arrangements (3), and spindled (3). The tubules were solid or hollow with the former being somewhat more common. Delicate septa were occasionally seen and were conspicuous in areas of one tumor. The stroma was abundant in 15 tumors with marked sclerosis in 4. The cells usually had pale to occasionally densely eosinophilic cytoplasm, but 6 tumors were composed of cells with prominent foamy cytoplasm, falling in the category of "lipid-rich" Sertoli cell tumor, and one had cells with clear non-foamy cytoplasm. Forty-four tumors were stage I (42 of them were stage Ia and 2 were stage Ic), 1 was stage II, 3 were stage III, and 6 were not adequately staged. Follow-up was available for 27 patients with stage I tumors, and all were alive and well at last follow-up except for 2 patients with stage Ia and 1 with stage Ic disease. Those 3 patients had pelvic-abdominal recurrences 18, 36, and 9 months, respectively, after the initial diagnosis. Two of the three clinically malignant stage I tumors had moderate to severe cytologic atypia and brisk mitotic activity (>5 or more mitoses/10 high power fields [HPFs]), and one of these had tumor cell necrosis. Among the 10 clinically benign stage I tumors with more than 5 years of follow-up, only 3 had >5 mitoses/10 HPFs, but none had more than mild cytologic atypia and none had tumor cell necrosis. Two of the three patients with stage III disease had follow-up information and one was alive at 16 months and the second developed splenic metastases 2 years after the initial diagnosis. Two of the three stage III tumors had at least moderate cytologic atypia and brisk mitotic activity. Immunohistochemical stains showed positivity for AE1/3-Cam5.2 in 15 of 23 tumors; Epithelial membrane antigen (EMA) was negative in all the tumors. Inhibin was positive in 18 of 22 tumors, calretinin in 10 of 20, CD99 in 19 of 22, vimentin in 17 of 18, smooth muscle actin in 4 of 18, neuron specific enolase in 8 of 16, S-100 in 2 of 20, and chromogranin was negative in all 21 cases studied. Although Sertoli cell tumors usually have a distinctive tubular pattern that facilitates the diagnosis, other patterns may occasionally predominate, causing confusion with various other primary and metastatic ovarian tumors. EMA, inhibin, and chromogranin represent the most helpful triad of immunomarkers serving to exclude two common mimics of Sertoli cell tumors (endometrioid carcinoma [inhibin-; EMA+; chromogranin-] and carcinoid tumor [inhibin-; EMA+; chromogranin+]). Although CD99 and calretinin are often expressed in these tumors, they are much less specific and not as helpful in the differential diagnosis. Most Sertoli cell tumors are stage I, unilateral, cytologically bland, and clinically benign, but occasional examples are high stage, and about 11% of stage I tumors have worrisome histologic features that may portend an adverse outcome. The tumors typically occur in young females, sometimes children who typically present with sexual precocity, and occasional patients have Peutz-Jeghers syndrome.

Abstract
A 23-year-old woman underwent resection of a tumorous right ovary after long-standing irregular genital bleeding. The tumor measured 50 x 30 mm and had a yellowish-white solid cut surface with scattered small cysts. The light microscopic diagnosis was a sex cord tumor with annular tubules. Ultrastructurally, the tumor cells had Charcot-Boettcher filaments and showed vimentin positivity by immunohistochemistry. A three-dimensional reconstruction study proved that the tumor cell nests had a ovoid outer margin and contained blind-ended ellipsoid hyaline bodies. This tumor is presumed to be a variant of sex cord/stromal tumor showing differentiation predominantly to Sertoli cells.

Abstract
Of 71 dogs with primary ovarian neoplasms, 12 (17%) had Sertoli-Leydig cell tumors. Five dogs had Sertoli-Leydig cell tumors, four had pure Sertoli cell tumors, and three had Sertoli-Leydig cell tumors with a retiform pattern. Variously differentiated Sertoli cells were seen in the Sertoli-Leydig cell tumors, and one of these metastasized to the peritoneum. The pure Sertoli cell tumors were similar to these tumors in male dogs. The retiform pattern in the third group of tumors was characterized by tubuloalveolar structures resembling rete testes. Heterologous elements were seen in seven tumors (58%)--enteric glands in three Sertoli-Leydig cell tumors and one Sertoli-Leydig cell tumor with retiform pattern, and neuroendocrine carcinoma in one pure Sertoli cell tumor and two Sertoli-Leydig cell tumors with retiform pattern. The uterus was examined in seven dogs, and six (87%) had endometrial hyperplasia.

Abstract
A pathologic study was done on four cases of ovarian sex cord tumor with annular tubules. All four tumors occurred in young women (11-24 years of age) and were not associated with the Peutz-Jeghers syndrome. Two patients had evidence of hyperestrinism. One patient who had metastasis to the retroperitoneum, left supraclavicular lymph node, and liver confirmed the malignant potential of this tumor. Gross examination revealed tumors that were solid, yellowish, and unilateral, with varying degrees of cystic degeneration. Microscopic examination showed simple or complex annular tubules with prominent basement membranes. Many tumor cells contained lipid in the cytoplasm. Ultrastructural study showed Charcot-Bottcher filaments in all four cases, indicating Sertoli cell differentiation. True lumens and microvilli were identified in one case. The classification of the sex cord tumor with annular tubules as a Sertoli cell tumor, annular tubular type was proposed on the basis of ultrastructural findings.

Abstract
A 33-year-old woman presenting with secondary amenorrhea and galactorrhea was found to have a Sertoli cell tumor of the ovary. The neoplasm also had a sex cord tumor with annular tubules (SCTAT) component. Further investigations revealed that in many respects the patient was endocrinologically pregnant. She had markedly elevated serum estrogen and progesterone levels and the endometrium demonstrated pronounced decidualization, but there was no evidence of actual pregnancy. Estrogen and progesterone were demonstrated by immunohistochemistry to be present in both the Sertoli cell and SCTAT portions of the tumor.

Abstract
The aim of this review is to give a reasonably concise resumé of our knowledge of the sex cord-stromal tumours of the ovary. Lipoid cell tumours of the ovary are often included within this broad category but this poorly defined and heterogenous group of neoplasms will not be considered here. This review is a selective one and no attempt is made to cover all aspects of sex cord-stromal tumours or to provide a complete bibliography. The histological features of many of the neoplasms in this group, particularly those which have been recently defined, are discussed but a consideration of differential histological diagnosis is excluded. The ultrastructural characteristics of the various neoplasms are considered only in terms of their relevance to histogenesis or metabolic activity.

Abstract
Estrogen-secreting Sertoli cell tumor of the ovary is rare. The few cases reported were characterized by metrorrhagia suggesting the hyperestrogenic state. An additional case of Sertoli cell tumor is reported in which the clinical picture is of secondary amenorrhea followed by metrorrhagia. The endocrinological status was investigated by hormonal assays showing a high level of estradiol, which was consistent with endometrial biopsy. A review of the literature together with a discussion on the histogenesis and diagnosis of the tumor is presented.

Abstract
An ovarian sex-cord tumor with annular tubules (SCTAT) and with Charcot-Böttcher bodies in a 29-year-old woman with primary infertility, secondary amenorrhea, and without evidence of the Peutz-Jeghers syndrome was studied by light and electron microscopy. At laparotomy, a right ovarian tumor was removed, and there was no evidence of metastases. The patient has been well and disease free for a period of 3 months after surgery. The tumor was histologically composed of nests of cells arranged in complex tubules with hyaline bodies. Ultrastructurally, cells were joined by specialized junctions along their lateral adjacent borders. Microvilli and cilia were absent. Concentrically arranged membranes were seen in the cytoplasm. Charcot-Böttcher filaments were seen in paranuclear region. The findings of Charcot-Böttcher filament in an ovarian SCTAT support the hypothesis of the Sertoli nature of this neoplasm.

Abstract
This report describes the ultrastructural and hormonal characteristics of the recently described large-cell calcifying Sertoli cell tumor of the testis, a rare subtype of pure Sertoli cell tumor. The ultrastructural findings showed similarity to normal Sertoli cells, pure Sertoli cell tumors, Sertoli cells in azoospermic human testes, and the Sertoli cell component of Sertoli-Leydig cell tumors. Ultrastructure indicated features common to steroid-producing cells. Testosterone and estradiol were demonstrated in the tumor by immunocytochemical and biochemical methods.

Abstract
Three new cases of sclerosing stromal tumor of the ovary have been studied by hormonal, immunohistochemical and electron microscopic analysis. The results confirm that this tumor may have hormonal activity. Ultrastructural study shows findings different from those previously reported. The authors propose an origin from the ovarian stroma with luteinization of stromal tumor cells.

Abstract
The clinical and light and electron microscopic findings of a moderately differentiated, virilizing, Sertoli-Leydig cell tumor (SLT) with pleomorphic rhabdomyosarcoma of the ovary are presented. The tumor recapitulates the primitive embryonal testis and rhabdomyogenesis, respectively. The natural history, including pathogenesis, of this peculiar and rare tumor is discussed in the light of the pertinent literature on SLT and ovarian rhabdomyosarcoma. It seems that when rhabdomyosarcoma is a significant or predominant component of SLT, as occurred in this case, the prognosis is poor and is that of rhabdomyosarcoma in general.

Abstract
A patient with recurrent Sertoli-Leydig cell tumor is described. The light and ultrastructural findings are illustrated. The tumor recurred first as a poorly differentiated tumor with rhabdomyoblastic differentiation. Following chemotherapy the next recurrence exhibited well differentiated Sertoli-Leydig cell elements. These findings may reflect the capability of this tumor type to undergo chemotherapeutic transformation similar to the transformation which has been described in germ cell tumors of the ovary and testis. This observation may be of importance in the clinical management of patients with poorly differentiated Sertoli-Leydig cell tumors.

Abstract
Gynandroblastoma is a rare, sex-cord stromal tumor of the ovary that shows morphologic evidence of female and male differentiation. Such a tumor produced masculinization in a 24-year-old woman, whose symptoms disappeared following removal of the tumor. By electron microscopy, the granulosa cell nests displayed Call-Exner (CE) bodies of the hyaline type composed of multiple layers of basal lamina resembling CE bodies of the normal graafian follicle. In contrast, CE bodies of a classic granulosa theca cell tumor were of the spongiform type, consisting of a space limited by a single basal lamina containing altered granulosa cells and cell processes. Both types of CE bodies are believed to arise following secretion by and/or degeneration of granulosa cells, the variation in morphology between the two resulting from differences in amounts of basal lamina deposited. The tubular components of the tumor resembled more closely the rete ovarii than did Sertoli cells, and its proposed that such structures be called by the alternate and less specific term "androblastoma." The identity of Leydig cells was established by demonstrated of intracytoplasmic Reinke crystals. Despite a difference in architectural pattern, there was a close ultrastructural resemblance between the different sex-cord components of the gynandroblastoma.

Abstract
Three tumors of the ovary containing Sertoli cells were studied by light and electron microscopy. Two of these tumors were well-differentiated neoplasms with epithelial cells often forming tubules. These cells were cylindrically shaped, contained round to oval nuclei and stood on a thin basement membrane. The cytoplasm was fibrillary and showed rough and smooth endoplasmic reticulum, lipid droplets and secretory granules. At the luminal borders the cells were often irregular and displayed apocrine-like activity. Having compared our data with results of studies from the literature of normal Sertoli cells, Sertoli cell adenomas of the testis and cells from other parts of the male reproductive system and those of normal ovarian stroma, we conclude that the Sertoli cell is most probably the cell of origin of these tumors. The third tumor was undifferentiated with a sarcomatoid appearance and contained islands of cartilage, which we consider to be metaplastic.

Abstract
Eleven cases of a small cell ovarian cancer associated with hypercalcemia that was reversed by removal of the tumor are reported and compared with three similar cases in the literature. The 14 cases account for 50% of recorded cases of ovarian-cancer-related hypercalcemia. The 14 tumors occurred in women between the age of 13 and 35, with an average of 22 years and, with two exceptions, behaved clinically in an aggressive fashion. Light and electron microscopic study confirmed the epithelial nature of the neoplasms but failed to disclose their specific subtype or origin.

Abstract
The authors describe two mucinous ovarian tumors that were hormonally active due to Sertoli-Leydig elements within the septal stroma. Carcinoid was also present in each case. The mesenchymal stromal cells within the septa of the mucinous tumors have undergone neoplastic proliferation with the Sertoli and Leydig differentiations, leading to the formation of arrhenoblastoma. The carcinoid component of these tumors is thought to have originated from argentaffin cells of the "intestinal" mucinous epithelium.

Abstract
The clinical and pathologic features of 28 Sertoli tumors of the ovary are presented. Seventeen of the 18 neoplasms had a functional effect. The effects were hyperestrinism (eight women), isosexual precocious puberty (three girls), virilization (four women), a progestational decidual reaction on the peritoneum (one woman), and a combination of virilizing and estrinizing signs (one woman). There were three histologic patterns: simple tubular, complex tubular, and folliculome lipidique. Two neoplasms recurred, both of which had the distinctive feature of invasion of the supporting stroma by individual and columns of tumor cells in the original tumors. Electron microscopic evaluation of three neoplasms disclosed. Charcot-Böttcher filaments unequivocally identifying the Sertoli differentiation of the predominant cells in the neoplasm. The identification by electron microscopy of a smaller population of cells within the three tumors similar to typical ovarian stromal cells suggests that Sertoli tumors arise from ovarian stromal cells.

Abstract
Ovarian Sertoli-Leydig cell tumors are rare, most of them being endocrinologically active and causing virilization. Their histogenesis and nomenclature are still under discussion. Six such tumors were identified in the Laboratory for Histopathology of the University Women's Hospital, Zürich. The clinical data as well as the macroscopic, microscopic and ultrastructural features of these tumors are analysed and discussed. In an attempt to clarify their histogenesis, the ultrastructural features of these tumors have been compared with those of two granulosa cell tumors as well as with those of a testis in a patient with testicular feminization. Our own results and a study of published data suggest that Sertoli-Leydig cell tumors arise from ovarian stroma. Because of their obvious morphological similarities to testicular structures they should be termed "gonadal stromal tumors of android type".

Abstract
The ultrastructural features of three granulosa cell tumors are presented. The neoplastic non-luteinized granulosa cells are characterized at sub-microscopical level by severely indented nuclei with prominent nucleoli, sparse to moderately developed predominantly granular endoplasmic reticulum, scanty lipids and lysosomes, small mitochondria with lamellar cristae and abundant intracytoplasmic filamentous material. The luteinized cells display a strongly developed tubular agranular endoplasmic reticulum and mitochondria with tubular cristae. These findings are compared with those of previous reports and discussed in relation to the well-known hormonal activity of these tumors.

Abstract
A case of pure Sertoli cell tumour of the ovary is described. Unusual features were its great size, lack of clinical hormonal activity and the presence of granulomas in its interstitium. Mitochondria with tubular christae are described for the first time in such a tumour.
