Unclassified type occupies about 5 to 10 percent of all ovarian sex cord stromal tumors. Diagnosis is very difficult and subjective because tumors show insufficient differentiation to ovarian or testicular line or display insufficient findings to diagnose as a gynandroblastoma in spite of divergent differentiation. To our knowledge sixty-two cases have been reported in the pathology literatures as yet. The behavior of this group of tumors has not been adequately studied but is similar to granulose cell tumors or Sertoli-Leydig cell tumors. We present a case of unclassified sex cord-stromal tumor which has been experienced in our hospital with brief review of the literature.

Sclerosing stromal tumor (SST) of the ovary is a rare, benign tumor. The most common clinical symptom is menstrual irregularity. Diagnosis of SST is often made by postoperative pathologic examination. The important differential diagnoses are other sex cord stromal tumors including fibroma, thecoma and etc. We present four cases of SST of the ovary during 10 years with a brief review of the literature.

The primary function of intraoperative frozen consultation is to provide an as accurate and prompt diagnosis as possible during surgery and to guide the surgeon in further management. However, the evaluation of frozen section (FS) is sometimes difficult because of suboptimal tissue quality and frozen artifacts compared with routinely processed tissue section. The pathologist responsible for the FS diagnosis requires experience and good judgment. Ovarian tumors are a heterogeneous group of tumors including primary surface epithelial tumors, germ cell tumors and sex cord-stromal tumors, secondary tumors, and other groups of tumors of uncertain histogenesis or nonspecific stroma. Intraoperative FS is a very important and reliable tool that guides the surgical management of ovarian tumors. In this review, the diagnostic key points for the pathologist and the implication of the FS diagnosis on the operator’s decisions are discussed.

We describe an unusual case of extragastrointestinal stromal tumor (EGIST) presenting as a scrotal mass. A 71-year-old man presented with a gradually enlarging scrotal mass with a 20-year duration. Physical examination revealed a huge (as large as volleyball), round, nontender mass occupying the whole scrotum, which was resected completely. Clinical and radiological findings did not comply with any other primary site disease. Under histological examination, the tumor showed a spindle cell pattern with low cellularity, absence of necrotic and mitotic features. immunohistochemical analysis revealed the tumor reactive for CD117 and CD34, while negative for smooth muscle actin, desmin and S-100 protein. To our knowledge, this is the first reported case of an EGIST involving the scrotum.

Sex cord-stromal tumors of the ovary are the third most common types of neoplasms that develop in the ovary and account for about 5-8% of all ovarian malignancies. Juvenile granulosa cell tumor (JGCT) is one of the sex cord-stromal tumors of the ovary has distinct differences from adult granulosa cell tumor (AJCT) with regard to clinical and pathological features as well as biological behavior most frequently occuring in the first two decades of life. Usually Call-exner bodies are rare, and luteinization is frequent in JGCT. The tumor may be solid, cystic, or both. In premenarcheal girls, juvenile granulosa cell tumor usually (82%) elicits the signs of sexual precocity. The tumor should removed as soon as the diagnosis is established. Surgery is the best treatment choice for low stage juvenile granulosa cell tumor in children, but for those with high stage juvenile granulosa cell tumor or recurrent tumor, the best treatment and sensitivity of tumor to radiation therapy and chemotherapy have not yet been determined clearly. About 90% are diagnosed in early stage so, prognosis of juvenile granulosa cell tumor in children is good in most cases, but tumor with more advanced stage has worse clinical outcome correlated with its stage, presence of ruptures, grade of nuclear atypia, degree of mitotic activity. And the clinical stage at the time of diagnosis is considered most important prognostic factor. We experienced a case of ruptured juvenile granulosa cell tumor so, we present a case with brief review of literature.

Sex cord stromal tumors (GCT) of the ovary compose just 5% of ovarian tumors. Most of them are granulosa cell tumors (GCT). There are two types of tumors, juvenile (JGCT) and adult type (AGCT), which have different clinical and histopathological features. JGCT represents only 5% of GCT. GCT is characterized by secretion of estrogen. Patients may present with vaginal bleeding in adult type, and sexual pseudoprecocity in juvenile type, as results of prolonged exposure to tumor-derived estrogen. Surgery is a principle of treatment and required for definite tissue diagnosis, staging, and tumor debulking. Survival of patients with GCT is generally excellent because most patients present with early stage disease. Because of the propensity of GCT to recur years after initial diagnosis, prolonged surveillance such as physical examination and serum tumor markers such as estradiol and inhibin is reasonable. We present 5 cases GCT, 4 AGCT and 1 JGCT, with brief review of literature.

Sclerosing stromal tumor (SST) of the ovary is a rare tumor derived from the sex cord stroma. This tumor was first described by Chalvaridjian and Scully in 1973. SST of the ovary is prevalence of 1.5% to 6% of ovarian stromal tumors. Patients are most commonly diagnosed in their 20s and 30s. There have been reports of SST postmenopausal women aged 65-, 67-, and 71 in the Republic of Korea; however, no report of this disease has been reported in women older than 80. In this study, we would like to report an 80-year-old postmenopausal woman who did not previously complain of any symptoms, and was finally diagnosed with SST. She was involved in a traffic accident, and huge pelvic mass was found during the evaluation of intra-abdominal hemorrhage. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed ; a final pathologic diagnosis reported SST.

Juvenile granulosa cell tumor (JGCT) is one of the sex cord stromal tumors of the ovary ocurring in the first two decades of life. These tumors are different from adult granulosa cell tumor (AJCT) with regard to clinical and pathological fetures. Follicles are often irregular, Call-exner bodies are rare, and luteinization is frequent. The tumor may be solid, cystic, or both. The most common presenting symptoms are abnormal uterine bleeding and pain. Breast swelling, pain and tenderness may also be associated with unopposed estrogen secretion by granulosa cell tumors. The tumor should be removed as soon as the diagnosis is estabilished. The juvenile granulosa cell tumor has a good overall prognosis because fewer than 5% of these tumors in children are malignant.

Steroid cell tumors, not otherwise specified, are rare ovarian sex cord-stromal tumors with malignant potential. The majority of these tumors produce steroids (testosterone is the most common) and various virilizing symptoms such as hirsutism, temporal balding and amenorrhea, may appear in patients. Executive history taking, physical examinations, CT or sonography and hormonal studies are helpful in the diagnosis, but the confirmation of diagnosis is made via a staging operation and pathology. Treatments include operation, chemotherapy (i.e., BEP), GnRH agonist therapy and radiotherapy. We experienced a case of steroid cell tumor, not otherwise specified, with massive ascites, and elevated CA125, which we wish to report with a brief review of the literature.

PURPOSE: To assess the value of CT for the differential diagnosis of malignant ovarian tumors. MATERIALS AND METHODS: We reviewed CT scans of 31 patients with surgically confirmed 46 malignant ovarian tumors. (29 epithelial tumors, 9 Krukenberg tumors, 6 germ cell tumors, and 2 sex cord-stromal tumors.) CT scans were evaluated for the mass (bilaterality, size, internal component, and margin), peritoneal spread pattern, ascites, invasion of adjacent organ, and lymphadenopathy. RESULT: Bilateral masses were seen in epithelial or Krukenberg tumor in 61.1%(11/18) and 80%(4/5) respectively. Epithelial tumors showed predominantly cystic mass(37.9%, 11/29), irregular margin(82.8%, 24/29) of mass, and accompanying peritoneal and omental spread (66.7%, 12/18), whileKrukenberg tumor showed predominantly solid mass(55.5%, 5/9), smooth margin of mass(100%, 5/5), and no peritoneal and omental spread. All cases with germ cell tumor or sex cord-stromal tumor showed unilateral mass. Relatively young aged, unilateral solid (66.7%, 4/6) tumors were germ cell tumor. Of these cases, septa within solid portionof mass were prominent in all dysgerminoma. (3/3) CONCLUSION: CT may be a valuable tool for the differential diagnosis of malignant ovarian tumors.
