Gynandroblastoma is an extremely rare sex cord-stromal tumor with both female (granulosa cell tumor) and male (Sertoli-Leydig cell tumor) elements. Juvenile granulosa cell tumors are also very rare and are so named because they usually occur in children and adolescents. A 71-year-old woman with right upper quadrant abdominal pain visited our hospital. Pelvic computed tomography showed a large multilocular cystic mass, suspected to be of ovarian origin. We performed a total abdominal hysterectomy (total abdominal hysterectomy was performed) with bilateral salpingooophorectomy. A 13-cm multilocular cystic mass with serous fluid was observed in her right ovary. Upon microscopic examination, the solid component of the mass showed both Sertoli-Leydig cell and juvenile granulosa cell differentiation, which we diagnosed as gynandroblastoma. Gynandroblastoma with a juvenile granulosa cell tumor component is extremely rare and, until now, only six cases have been reported in the English literature. We report the first gynandroblastoma with a juvenile granulosa cell tumor component diagnosed in an elderly patient, along with a literature review.

Abstract PDF

Background
Immature teratoma (IT) is a tumor containing immature neuroectodermal tissue, primarily in the form of neuroepithelial tubules. However, the diagnosis of tumors containing only cellular neuroglial tissue (CNT) without distinct neuroepithelial tubules is often difficult, since the histological characteristics of immature neuroectodermal tissues remain unclear. Here, we examined the significance of CNT and tried to define immature neuroectodermal tissues by comparing the histological features of neuroglial tissues between mature teratoma (MT) and IT.
Methods
The histological features of neuroglial tissue, including the cellularity, border between the neuroglial and adjacent tissues, cellular composition, mitotic index, Ki-67 proliferation rate, presence or absence of tissue necrosis, vascularity, and endothelial hyperplasia, were compared between 91 MT and 35 IT cases.
Results
CNTs with a cellularity grade of ≥ 2 were observed in 96% of IT cases and 4% of MT cases (p < .001); however, CNT with a cellularity grade of 3 in MT cases was confined to the histologically distinct granular layer of mature cerebellar tissue. Moreover, CNT in IT exhibited significantly higher rates of Ki-67 proliferation, mitoses, and necrosis than those in MT (p < .001). Furthermore, an infiltrative border of neuroglial tissue and glomeruloid endothelial hyperplasia were significantly more frequent in IT cases than in MT cases (p < .001).
Conclusions
Our results suggest that if CNT with a cellularity grade of ≥ 2 is not a component of cerebellar tissue, such cases should be diagnosed as IT containing immature neuroectodermal tissue, particularly if they exhibit an infiltrative border, mitoses, necrosis, and increased Ki-67 proliferation.

Abstract PDF

We describe an ovarian mucinous neoplasm that histologically resembles lobular endocervical glandular hyperplasia (LEGH) containing pyloric gland type mucin in a patient with Peutz-Jeghers syndrome (PJS). Although ovarian mucinous tumors rarely occur in PJS patients, their pyloric gland phenotype has not been clearly determined. The histopathologic features of the ovarian mucinous tumor were reminiscent of LEGH. The cytoplasmic mucin was stained with periodic acid-Schiff reaction after diastase treatment but was negative for Alcian blue pH 2.5, suggesting the presence of neutral mucin. Immunohistochemically, the epithelium expressed various gastric markers, including MUC6, HIK1083, and carbonic anhydrase-IX. Multiple ligation-dependent probe amplification detected a germline heterozygous deletion mutation at exons 1–7 of the STK11 gene (c.1-?_920+?del) in peripheral blood leukocytes and mosaic loss of heterozygosity in ovarian tumor tissue. Considering that LEGH and/or gastric-type cervical adenocarcinoma can be found in patients with PJS carrying germline and/or somatic STK11 mutations, our case indicates that STK11 mutations have an important role in the proliferation of pyloric-phenotype mucinous epithelium at various anatomical locations.

Abstract PDF

Ovarian clear cell adenocarcinomas (CCACs) are frequently associated with endometriosis and, less often with clear cell adenofibromas (CCAFs). We encountered a case of ovarian CCAC arising from benign and borderline adenofibromas of the clear cell and endometrioid types with endometriosis in a 53-year-old woman. Regions of the adenofibromas showed transformation to CCAC and regions of the endometriosis showed atypical endometriotic cysts. This case demonstrates that CCAC can arise from CCAF or endometriosis.

Abstract PDF

Gliomatosis peritonei (GP) indicates the peritoneal implantation of mature neuroglial tissue and is usually accompanied by ovarian mature or immature teratoma. Here, we report a case of ovarian immature teratoma associated with gliomatosis involving the peritoneum, lymph nodes and Douglas' pouch, where gliomatosis coexisted with endometriosis. As far as we know, only seven cases of GP have been reported as coexisting with endometriosis. Eight cases with mature glial tissue in the lymph nodes, i.e., nodal gliomatosis, have been published either in association with GP or in its absence. Metaplasia of pluripotent coelomic stem cells has been suggested to be responsible for the pathogenesis of endometriosis and GP rather than implantation metastases of ovarian teratomatous tumor with varying maturation. This theory is also applied to GP independently of ovarian teratomatous tumors. To the best of our knowledge, nodal gliomatosis coexisting with GP and also involving endometriosis has not yet been reported.

Abstract PDF

Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports.

Abstract PDF

Background

Cancer registration in Korea has a longer than 30-years of history, during which time cancer registration has improved and become well-organized. Cancer registries are fundamental for cancer control and multi-center collaborative research. However, there have been discrepancies in assigning behavior codes. Thus, we intend to propose appropriate behavior codes for the International Classification of Disease Oncology, 3rd edition (ICD-O-3) for microinvasive tumors of the ovary and breast not only to improve the quality of the cancer registry but also to prevent conflicts.

Methods

As in series I, two pathology study groups and the Cancer Registration Committee of the Korean Society of Pathologists (KSP) participated. To prepare a questionnaire on provisional behavior code, the relevant subjects were discussed in the workshop, and consensus was obtained by convergence of opinion from members of KSP.

Results

Microinvasive tumor of the breast should be designated as a microinvasive carcinoma which was proposed as malignant tumor (/3). Serous borderline tumor with microinvasion of the ovary was proposed as borderline tumor (/1), and mucinous borderline tumor with microinvasion of the ovary as either borderline (/1) or carcinoma (/3) according to the tumor cell nature.

Conclusions

Some issues should be elucidated with the accumulation of more experience and knowledge. Here, however, we present our second proposal.

Abstract PDF

Ovarian primary malignant melanoma is very uncommon with only 44 reported cases in the literature. A 71-year-old woman with an ovarian mass and multiple nodules in the liver presented to our hospital. She was treated with bilateral salpingo-oophorectomy, and malignant melanoma was found in the mature cystic teratoma of the ovary. Malignant melanoma cells were also found in the ascitic fluid. She died 5 months later. Here we report a very uncommon case of malignant melanoma arising in an ovarian mature cystic teratoma with a review of the literature.

Abstract PDF

Ovarian large cell neuroendocrine carcinoma is a rare tumor that is usually associated with surface epithelial tumors. Mucinous tumors are most common surface epithelial component identified in reported cases. Ovarian mucinous tumor associated with large cell neuroendocrine carcinoma is almost always an intestinal type. However, large cell neuroendocrine carcinoma associated with pure mucinous borderline tumor of endocervical-like type has not been described previously. The present case report describes a large cell neuroendocrine carcinoma associated with endocervical-like mucinous borderline tumor of the ovary in a 35-year-old woman. The tumor was confirmed by histopathology and immunohistochemistry. A review of the pertinent literature is included.

Abstract PDF

Accessory ovaries are rare entities defined as small portions of ovarian tissue situated near, and connected to, the normally placed ovary. Tumors arising in accessory ovaries are extremely rare. In particular, a fibroma arising from an accessory ovary has not been reported in the literature. We describe such a case with a fibroma developing in an accessory ovary. A 53-year-old multiparous woman presented with abdominal pain for 2 months. Pelvic computed tomography revealed 11.0x8.0x6.0 cm sized cystic mass with a thick septal wall in right adnexa. The preoperative diagnosis was a borderline ovarian tumor. Furthermore, a laparotomy showed a cystic mass connected to the right ovary by stalk. The bilateral eutopic ovaries were completely normal. Histologically, an accessory ovary was replaced by a fibroma accompanied by extensive cystic change.

Abstract PDF

Herein, we present two cases of Brenner tumor, a rarely occurring neoplasm in the ovaries, obtained via intraoperative fine needle aspiration. The borderline Brenner tumor exhibited marked squamous metaplasia, characterized by individually distributed atypical squamous cells. A benign Brenner tumor associated with mucinous cystadenoma evidenced typical mucinous metaplastic features and transitional foci. These distinctive features may prove helpful in differential diagnosis of varied ovarian tumors, and particularly for intraoperative consultation.

Abstract PDF

Primary ovarian angiosarcoma is very rare with only 27 cases reported so far in the medical literature. We report here on a rare case of ovarian microinvasive mucinous carcinoma that was coexistent with angiosarcoma in a 54-year-old woman. The tumor was a 26x19x10 cm-sized multilocular cystic mass with a 4x3 cm-sized solid hematoma-like nodule in the center. Microscopically, it was composed mostly of mucinous tumor of various grades from borderline to microinvasive carcinoma. The hematoma-like area turned out to be an angiosarcoma, composed of pleomorphic cells that formed slit-like spaces, spindle cells that formed short fascicles and anastomosing vascular channels with atypical endothelial cells. All these cells were positive for CD31, CD34 and factor VIII-related antigen. The patient developed peritoneal and pleural metastases, which were angiosarcoma and mucinous carcinoma, respectively. We believe this case is only the fourth example of an ovarian collision tumor of angiosarcoma and surface epithelial tumor.

Abstract PDF: BACKGROUND
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy causing anovulation in women of childbearing age. It has been well established that estrogen receptor-alpha knockout (ERalphaKO) mice display several pathologic ovarian phenotypes of PCOS. The aims of this study were to determine ovarian pathology in new ERalphaKO mice using a CreloxP approach and intra-ovarian ERalpha function as regulating key aspects of PCOS.
METHODS
ERalphaKO mice, which were deficient in exon 3 of the ERalpha gene, were used. Immunohistochemical studies were done on ovaries of control and ERalphaKO mice using antibodies specific to ERalpha, ERbeta, inhibin-alpha, and alpha-smooth muscle actin (SMA), as well as histochemical staining using Sudan black-B.
RESULTS
All ovaries of ERalphaKO mice were larger than control mouse ovaries and displayed a disrupted theca-interstitial tissue organization, multiple atretic follicles and multiple hemorrhagic cysts. None of the ERalphaKO mouse ovaries showed a corpus luteum. In addition, heavy deposition of Sudan black-B positive foamy cells was seen. The theca externa of preantral immature follicles and hemorrhagic cysts showed strong expression of alpha-SMA.
CONCLUSIONS
ERalphaKO mice show hemorrhagic polycystic ovaries and hyperplasia of the theca externa. This study demonstrates that the ERalpha is the functional key to the pathogenesis of PCOS.

Abstract PDF: A 50-year-old female patient presented with anorexia and weight loss. Pelvic computed tomography revealed a 12.5 x 7.3 cm heterogeneous mass in the left ovary. About 30% of the tumor was occupied by a mature cystic teratoma. The remaining solid portion was composed of fibrous and histiocytic elements, arranged in storiform patterns admixed with bizarre giant cells. The mitotic index was 8 per 10 high power fields, including atypical mitoses. The only immunopositivity was for vimentin. The tumor was diagnosed as a malignant fibrous histiocytoma arising in a mature cystic teratoma. To the best of our knowledge, this is only the third such case in the English language literature.

Abstract PDF: Ovarian endometrioid adenocarcinoma (EAC) with a yolk sac tumor (YST) component is extremely rare. Only twelve cases have been reported in the English literature. We report here two additional cases of this rare tumor. The YST component showed classic microscopic features, and immunohistochemically stained positive for alpha-fetoprotein (AFP), but negative for cytokeratin 7 (CK7), epithelial membrane antigen (EMA), estrogen receptor (ER) and progesterone receptor (PR). The EAC appeared to blend into the YST in several areas and immunohistochemically stained positive for CK7, EMA, ER, and PR, but negative for AFP.
