Well-differentiated papillary mesothelioma (WDPM) of the peritoneum is considered to be a distinct subtype of peritoneal mesothelioma and has mostly behaved in a benign fashion. We report a case of WDPM in a 48-year-old-woman. It was incidentally found during a hysterectomy for a uterine cervical carcinoma. Grossly, the tumor was composed of multiple peritoneal nodules, measuring up to 2 cm. Microscopically, the nodules showed well-developed papillae lined by a single layer of cuboidal mesothelial cells. Immunohistochemical staining revealed a positive reaction for cytokeratin and a negative reacion for carcinoembryonic antigen and Leu-M1. Ultrastructurally, the tumor cells showed numerous long, slender microvilli and desmosomes.

Recently developed new classifications (Holland, Van Nuys, modified Lagios) of ductal carcinoma in situ (DCIS) linked to outcome have emphasized the importance of nuclear morphology rather than architecture. We have evaluated these three classifications in ductal carcinomas composed of in situ and invasive carcinomas. The reproducibility of three classifications was assessed (n=49), and the histological grade of the DCIS was compared with the histologic differentiation (modified Bloom & Richardson method) and nuclear grade (modified Black method) of the coexisting invasive ductal carcinoma (n=45). According to Holland classification, the DCIS component was poorly differentiated in 51.0%, intermediately differentiated in 40.8%, and well differentiated in 8.2%. Using the Van Nuys classification, the DCIS component was group 3 (high grade with or without necrosis) in 44.9%, group 2 (non-high grade with necrosis) in 28.6%, and group 1 (non-high grade without necrosis) in 26.5%. According to the modified Lagios classification, the DCIS component was high-grade in 42.8%, intermediate-grade in 32.7%, and low-grade in 24.5%. The histologic grades of the three classifications revealed significant correlations between Holland and Van Nuys classification (p<0.0001) and between Holland and modified Lagios classification (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. The reproducibility of classification of the DCIS was 71.4% in the Holland, 61.2% in the Van Nuys, and 55.1% in the modified Lagios classifications. The grade of the DCIS showed significant correlation with the grade of coexisting invasive ductal carcinoma (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. In conclusion, DCIS grade, determined by the Holland, Van Nuys or modified Lagios classifications, is closely correlated with the histologic grade of the invasive ductal component in tumors composed of in situ and invasive ductal carcinoma, and may be a useful factor to estimate clinical behavior of DCIS. In our experience the Holland classification is recommended for DCIS classification due to its high reproducibility.

Osteochondrodysplasia is a heterogeneous group of disorders appearing short limbed dwarfism. Because many of these entities are lethal and hereditary, an accurate diagnosis is mandatory. The purpose of this study is to define the clinicopathologic features and radiologic findings of osteochondrodysplasia. We reviewed 29 autopsy cases of congenital short limbed dwarfism, consisting of thanatophoric dysplasia (TD) (12 cases), osteogenesis imperfecta (OI) (12 cases), asphyxiating thoracic dysplasia (ATD) (3 cases), short-rib-polydactyly syndrome (SRPS) (1 case) and hypochondrogenesis (1 case). The gestational age ranged from 16 to 41 weeks. Of 6 fetuses that were born alive, 3 were ATD, 2 were TD and 1 was hypochondrogenesis. TD was frequently complicated by hydramnios. Of 8 cases studied chromosomally, only 1 showed chromosomal abnormality -46XY, inv 9. Intrauterine growth retardation was frequently associated with OI. Pulmonary hypoplasia was present in 23 cases (79%), including all cases of ATD, SRPS and hypochondrogenesis, 11 in TD and 7 in OI. Other associated anomalies were present in 17 cases (59%).

Pseudoangiomatous stromal hyperplasia (PASH) of the breast occurs in premenopausal women and is characterized by anastomosing channels lined by spindle cells. It has been suggested to be of hormonal origin. This unusual condition may also be mistaken for a vascular tumor. We analyzed eight cases of PASH of the breast in Samsung Cheil Hospital from 1992 through 1998. All patients were premenopausal and had painless breast lump. Clinical diagnoses were fibroadenomas. Grossly, the masses were well circumscribed, nonhemorrhagic and measure 2.2 to 5 cm. Histologically, they consisted of complex interanastomosing channels lined by slender spindle cells, which resembled low grade angiosarcoma. Cells that line the interanastomosing channels showed no immunoreactivity for Factor VIII and electron microscopic findings consistent with fibroblast. All patients were treated with surgical excision and none of them had recurrence for 1 to 69 months (mean: 19 months) postoperatively. Pathologic diagnosis of PASH may be difficult unless the pathologists are aware of the presence of a mass lesion and appreciate the characteristic stromal changes. PASH should be included in the differential diagnosis of a circumscribed mass, especially in the premenopausal women.

Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.

Liver cell adenoma is uncommon and most often affects women of reproductive age; it is often associated with use of oral contraceptives. It is a very rare benign tumor of the liver in males and associated with use of anabolic steroids or glycogen storage disease type I. The surgical treatment remains controversial. We experienced 3 cases of male liver cell adenoma without use of anabolic steroids or glycogen storage disease. We performed right lobectomy of liver in 2 cases of mass on right lobe and performed mass enucleation with cholecystectomy in another case of mass on left medial segment.

OBJECTIVE: The goal of this study was to examine the association between IQ and suicide in psychiatric patients. METHODS: We conducted a nested case-control study using data obtained from psychiatric patients affiliated with a general hospital in Seoul, Korea. In a one-to-two ratio the psychiatric patients who died of suicide (Suicide Group; n=35) were matched to those who didn't (Non-suicide Group; n=70) by age, gender, psychiatric diagnosis and approximate time of first treatment. IQ was measured using the Korean version of the Wechsler Adult Intelligence Scale-Revised. RESULTS: There were no significant differences in any type of IQ between suicide patients and non-suicide patients. Logistic regression showed no evidence of an association between IQ and suicide. CONCLUSION: These results do not support the existence of an association between IQ and suicide.
