Granulocytic sarcoma is a rare localized tumor composed of granulocytic precusor cells. Granu-locytic sarcoma occurs in a variety of clinical conditions and it is often misdiagnosed histologically. Differential diagnosis frorh lymphoma or nonhematopoietic malignancies such as undifferentiated carcinoma or sarcoma is difficult in the routing histologic examination. An evaluation of clinical and histopathologic features was done on 4 cases of granulocytic sarcoma which were diagnosed at Pusan Paik Hospital from 1988 to 1992. During the period, 282 cases of myelogenous leukemia were diagnosed. Immunohistochemical reaction for lysozyme, myelopero-xidase, leukocyte common antigen, epthelial membrane antigen and cytokeratin was assessed comparing to lymphoma and undifferentiated carcinoma. The histologic features of the granulocytic sarcoma revealed thin nuclear membrane, fine chromatin pattern and one or two small nucleoli. It also often involved the vascular wall and infiltrated the native structures without destruction. Immunohistochemical stain revealed that all(4 cases) of granulocytic sarcoma showed diffuse and strong positivity for myeloperoxidase, and partial but strong positivity for lysozyme. One case of granulocytic sarcoma was negative and 3 cases revealed focal positive reaction for LCA, and all 4 cases was negative for cytokeratin and EMA. In summary, careful observation under light microscopy with immunohistochemical stain for myeloperoxidase, lysozyme, and LCA is helpful in the differential diagnosis of granulocytic sarcoma from malignant lymphoma and cytokeratin and EMA is useful for differential diagnosis from undifferentiated carcinoma.

Sirenomelia is a severe form of caudal regression syndrome that results in a fusion of the lower extremities, which is not compatible with life. A various spectrum of anomalies affecting primarily the musculoskeletal, genitourinary and gastrointestinal systems also can occur. This rare malformation has a reported incidence rate of approximately 1 in 60,000 births, with a range of 1 to 1 percent of all malformed infants. We experienced a sirenomelic case with combined anomalies of genitourinary, cardiovascular and gastrointestinal systems. Maternal obstetric history revealed oligohydramnios and intrauterine fetal growth retardation, and the baby was spontaneously delivered at 37 weeks of gestational age, but died I hour after birth.

The aim of the present study is to demonstrate the usefulness of intraoperative fine needle aspiration (FNA) of pancreatic lesions in 30 patients. A conclusive diagnosis was done in 27 patients and the diagnoses of three patients were deferred. No complications followed the procedure. Based on histologic findings of the resected specimens in 20 cases and of cell blocks in 10 cases, the final diagnoses were adenocarcinoma in 19 cases, chronic pancreatitis in nine cases and tuberculosis in two cases. The sensitivity, specificity and diagnostic accuracy were 95%, 100% and 96% resepectively and there were no false positives. The smear of aspirate was stained with toluidine blue and examined by light microscope. The presence of there-dimensional clusters of disoriented cells and the increased nuclear/cytoplasmic ratio with large prominent nucleoli were the most helpful criteria for a diagnosis of malignancy in the pancreas. The intraoperative FNA of pancreatic lesions was considered as a simple, safe, and highly specific and sensitive tool in differentiating benign from malignant lesions. The intraoperative FNA can be recommended as the first tool of choice of intraoperative diagnostic procedure in lesions of the pancreas.

Heterotopic pregnancy occurs when an intrauterine pregnancy co-exists with an ectopic pregnancy. It is a potentially fatal condition, rarely occuring in natural conception cycle. But its incidence is increased since the rise in PID, pelvic surgery, IUD, and advent of assisted reproductive technology involving use of superovulatory drugs and/or in vitro-fertilization. We present a case of intrauterine twin pregnancy and right tubal pregnancy following treatment with in vitro-fertilization. The right tubal pregnancy was diagnosed after rupturing at 6th gestational weeks, and resected via laparoscopy. And healthy twin babies were delivered without complication at 38th gestational week. So we report this case with a brief review of the literatures.

Malignant transformation of benign cystic teratomas of the ovary is rare, with an incidence rate of 1-3%. The most common malignancy associated with benign cystic teratoma of the ovary is squamous cell carcinoma, which represents 90% of malignant transformations, followed by adenocarcinoma and carcinoid. Primary malignant neuroectodermal tumor in a mature cystic teratoma is extremely rare and microscopically can be subclassified as differentiated, primitive, and anaplatic. We experienced a case of primitive neuroectodermal tumor (PNET) associated with mature cystic teratoma of the ovary in a 11-year-old girl. Grossly, the ovary was a unilocular cyst which contained sebum material and disclosed several large, yellow to gray-tan polypoid excresences attached to the inner cystic wall. Except a large, fish-flesh, soft mass, the other polypoid masses were covered with sebum and contained small pieces of cartilage and tooth, and microscopically represented as mature teratoma. The large, fish-flesh, soft mass disclosed sheets and lobules of closely packed small cells with thin fibrovascular septa, which frequently replacing and encroaching the mature cystic teratoma. The small tumor cells were uniform and made up of round to oval nuclei with coarse chromatin and prominent nucleoli, very similar to those of PNET of the central nervous system.

p53 gene alterations in the ovarian cancers are regarded as early events in the whole process of carcinogenesis. This study is intended to compare p53 protein expression rate in the ovarian surface epithelial tumors according to histologic types, degree of malignancy and differentiation. 134 cases of ovarian epithelial tumors including 26 cases of serous cystadenoma, 7 cases of serous borderline malignancy, 15 cases of serous cystadenocarcinoma, 40 cases of mucinous cystadenoma, 21 cases of mucinous borderline malignancy, 20 cases of mucinous cystadenocarcinoma, 4 cases of endometrioid carcinoma, and 1 case of clear cell carcinoma were studied. Immunohistochemistry using monoclonal p53 antibody(DO-7) was applied to the routine formalin-fixed paraffin embedded tissue. The results were as follows; 1. No immunohistochemical positivity of p53 protein was found in all 66 cases of benign serous and mucinous tumors studied. 2. There was no significant difference of p53 protein expression between serous and mucinous malignant tumors. 3. The expression rate of p53 protein exhibited a statistically significant difference between borderline(42%) and malignant(74%) ovarian surface epithelial tumors (p<0.05). 4. The expression rate of p53 protein of poorly differentiated carcinomas(100%) was higher than those of moderately (88%) and well differentiated carcinomas(60%), but there was no statistical significance. In summary, p53 protein expression might be a good indicator of malignant transformation of the ovarian surface epithelial tumors.
