1.Endometrial Ossification: Clinical and pathological analysis of 7 cases.
Korean Journal of Pathology 1996;30(3):238-244
Endometrial ossifications in seven patients who presented with secondary or primary infertility were described. Herein, we described step-by-step bone forming process in the endometrium and we compared the clinicopathological features of metaplastic ossification and fetal remnants. In five of seven patients, metaplasia was unquestionable etiology of ossification, which was ocquired in the healing process of postabortion endometritis. Ossifications were recurred during the follow-up periods after total hysteroscopic removal in 2 cases. Three cases were followed by normal pregnancy, after total hysteroscopic removal of bony spicules in 2 cases and with retaining of bony spicules in 1 case. In one other case, bony spicules of fetal remnants were verified by multiple fetal hair shafts and endochondral bone formation. Therefore, the cause of endometrial ossification can only be determined by histological findings and careful past obstetric history.

3.Effects of Progesterone Treatment on the Squamous or Morular Metaplasia Associated with Endometrial Hyperplasia.
Korean Journal of Pathology 1996;30(8):680-686
During evaluation of follow-up curettage of endometrial hyperplasia after progesterone treatment, we have noticed that the foci of squamous or morular metaplasia are persistent or even markedly increased after the hyperplastic glands have all disappeared. These observations have led us to study the histological changes of squamous or morular metaplasia in the hyperplastic endometrium after progesterone treatment and to examine the changes of estrogen receptors(ER) and progesterone receptors(PR) to find out, if there is any pathogenetic role of progesterone administration on the squamous or morular metaplasia. Squamous or morular metaplasia was associated in 21 cases (13.5 %) out of 156 endometrial hyperplasia during the study periods and all of them were associated with complex hyperplasia, but not associated with simple hyperplasia. At follow-up curettage after progesterone treatment, squamous metaplasia newly appeared in 3 cases(20 %), markedly increased in 4 cases(26.7%), persisted in 4 cases(26.7%) and decreased in 4 cases(26.7%), even after hyperplastic glands have all disappeared or were markedly decreased. On immunohistochemical staining, metaplastic foci showed ER- and PR- in 13 cases (87 %) in contrast to the surrounding endometrium and the remaining 2 cases showed minimal ER+ and PR+ confined to several nuclei. Intensity or staining pattern of ER and PR in metaplastic foci were not changed with progesterone treatment. In the background endometrium, intensity of glandular ER+ and PR + was higher than that of the stroma at the initial curettage, however, progesterone treatment predominantly down-regulated glandular ER+ more than stromal ER+. Increment or persistence of squamous metaplasia along the progesterone treatment seemingly would implicate hormonal influences as playing a significant role in the formation of squamous or morular metaplasia and the absence of cellular receptors for these hormones in the metaplastic foci may suggest qualitative changes in the receptors.

Small cell carcinoma of the ovary is rare malignancy occurring in women under 40 years of age(average, 23 years), which is associated with hypercalcemia in two thirds of cases. Its histogenesis is uncertain, but the possibilities of common epithelial, neuroendocrine, sex cord stromal and germ cell origin are suggested. All reported cases were proved to have rapid fatal course despite various therapy and 5 years suvival rate was only 10%. We report one case of a 20-year old woman with primary small cell carcinoma of the left ovary. The ovary was markedly enlarged and completely replaced by a mass, measuring 21x16x8 cm. Microscopic examination revealed dimorphic population of small and large malignant cell producing immature follicle-like structure which is characteristic of small cell carcinoma of the ovary. These pathological findings were similar to those of granulosa cell tumor, which is required to make differential diagnosis from small cell carcinoma. Immunohistochemical stains for cytokeratin and vimentin were positive, but those for S-100 protein and NSE were negative. One month after the initial operation, the tumor has recurred and the second and the second palliative operation followed by 3 cycles of chemotherapy was done. The patient showed disseminated metastasis at present time.

Clear cell sarcoma of tendons and aponeuroses is the term coined by Enzinger in 1965 to describe a rare but unique type of soft tisse neoplasm whose cells characteristically have the capacity to produce melanin. The authors experienced a case of 64-year old female who presented with a 6x5x4 cm sized mass deeply seated in the left popliteal fossa. The mass was firm and multinodular, and on cut section revealed patches of brown black pigmentation. Histologically the tumor was composed of round to fusiform cells with clear or pale eosinophilic cytoplasm that contained small amounts of glycogen, separated into compact nests or short fascicles by delicate septa of fibrous tissue. The brown black pigment seen in tumor cells and stroma was proven to be melanin by special stain, and ultrastructural examination showed melanosomes in varying stages of development dispersed freely in the cytoplasm or in the lysosomes. These findings strongly support the view that clear cell sarcoma is a tumor of neural crest origin rather than of tenosynovial mesenchyme origin, and is a soft tissue variant of malignant melanoma.

Gestational trophoblastic disease associated with the tubal pregnancy is uncommon, and the incidence has been described as 1/5000 tubal pregnancy. We have experienced a case of metastatic gestational trophoblastic disease(GTD) in the lung occuring with complete hydatidiform mole arising in tubal pregnancy. The patient was a 39-year-old, G4P2A2L2 woman with amenorrhea for 5 weeks. Ectopic pregnancy in the right fallopian tube was suspected on transvaginal ultrasonogram. A right adnexectomy was performed. The fallopian tube was markedly dilated and ruptured. The right ovary and a round hematoma had adhered to the external surface of the fallopian tube. On gross examination, no molar tissue was identified. On microscopic examination, the lumen of the dilated fallopian tube was filled with blood clots admixed with several chorionic villi showing hydropic swelling and marked proliferation of atypical trophoblasts. Proliferating syncytio-and cytotrophoblasts invaded the wall of the blood vessels of the fallopian tube and sheets of trophoblasts and some villi were identified in the lumen of blood vessels. Multiple pulmonary nodules thought to be metastatic nodules were identified in the chest X-ray and serum beta-HCG had increased 2 weeks later. This case indicates that a careful pathological examination in the ectopic pregnancy is mandatory, because tubal GTD is not clinically distinguishable from ordinary tubal pregnancy.

Luteal phase defect (LPD) is an ovulatory disorder of considerable clinical importance that leads to delayed endometrial maturation and inadequate endometrium for blastocyst implantation. This disorder is implicated in infertility and recurrent spontaneous abortion. We analyzed the endometrial histological maturation, and the estrogen receptor(ER) and progesterone receptor(PR) status in patients with unexplained delayed ovulation, and in patients with ovulation induction by clomiphen citrate. The purpose of this study was to determine whether the length of the follicular phase influences the endometrial histological maturation and the hormonal receptor status, and to know the effect of clomiphen citrate on the endometrium. In the delayed ovulation group, the endometrium was characterized by an irregular outpouching and dilated lumina of the glands, a decreased secretory activity and predecidualization, and a decreased number of granulocytes in the stroma. In the clomiphen citrate-ovulation induction group, glandular proliferation was markedly diminished with poorly convoluted and narrow glands, secretory activity was decreased, stroma was undecidualized, and there was an absence of granulocytes. ER expression was increased in the glandular epithelium in the delayed ovulation group, and both ER and PR expressions were markedly decreased in the glandular epithelium and stromal cells in the ovulation induction group. Endometrial maturation and differentiation may be diminished by increased estrogenic and relatively deficient progesterone effects in patients with delayed ovulation. The hormonal receptor status might also be influenced by hormonal changes. Clomiphen citrate successfully induced ovulation in patients with delayed ovulation, however, endometrial proliferation and maturation were markedly suppressed. This might be related to the lower pregnancy rate and higher abortion rate in patients with clomiphen citrate induced ovulation.

PSTT has been established as a separate entity distinct from choriocarcinoma since 1983, because of its different morphological features, biologic behavior and response to chemotherapy. Most cases of PSTT have indolent clinical courses, but there have been several reports showing malignant behavior resulted in death of the patient. We report a case of PSTT showing vaginal metastatis. In biopsy specimen, it was difficult to make differential diagnosis from squamous cell carcinoma of uterine cervix due to uniform and mononuclear cytologic characteristics. Immunohistochemical stains for hPL and hCG were not typical for either PSTT or choriocarcinoma. We suggest that poorly differentiated PSTT may synthesize the lesser amount of hPL than typical PSTT and it may behave more aggressively.

Five cases of ovarian serous borderline tumor associated with multiple peritoneal implants were analysed. The age of 5 patients ranged from 34 to 45(mean: 39) years at the time of diagnosis. Two patients presented with secondary infertility underwent hyperstimulation of the ovary under the in vitro fertilization program. One patient was presented with abdominal pain and the remaining two with lower abdominal mass accompanied by abdominal pain. Serous surface papilloma of borderline malignancy, involving one or both ovaries, was present in all 5 cases and papillary serous cystic tumor of borderline malignancy was associated simultaneously in one or both ovaries in all cases. Marked adhesions between the pelvic organs, and multiple granularities and nodularities of the omentum and peritoneum were noted. Microscopically, the peritoneal lesions were composed of noninvasive implants of tumor cells and pasmmoma bodies on the surface of entire pelvic and abdominal organs. Flow cytometric analysis of nuclear DNA content from paraffin-embedded tissue fo primary ovarian tumor classified as aneuploidy in 3 cases and as diploidy in 2 cases. The DNA index of the aneuploid tumors ranged from 1.21 to 1.37. Four patients underwent hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy in which two were followed by chemotherapy and one case underwent bilateral salpingo-oophorectomy.
