Wilms' tumor is the most common urinary tract neoplasm and one of the most frequent solid abdominal malignant tumors of childhood, usually diagnosed between the ages of 2 and 5 years. Typically, it is manifested as an asymptomatic unilateral or upper abdominal mass. Abdimonal pain after some traumatic incident, fever, anemia, hematuria and hypertension are other patterns of presentation. In a considerable number of these patients, pulmonary metastases are present at the time of primary diagnosis. But, the initial presentation of acute pulmonary tumor emboli without surgical manipulation is very rare. We describe a sudden unexpected infantile death case diagnosed as pulmonary tumor embolism preexisting Wilms tumor. To our knowledge, this is the initial autopsy presentation of Wilms tumor with tumor embolism as sudden and unexpected death in Korea.

To observe developing process of human fetal skin during intrauterine life, morphological studies in light microscopic level were made based on 27 human embryos and 76 fetuses ranging from 4 to 40 gestation weeks. The fetuses were the products of induced abortion and were found to have no associated diseases of congenital anomalies at the autopsy. Ten different portions of the body were sampled and examined. They were scalp, forehead, face, chest, abdomen, back, palm, sole, finger and toe. In embryos two different portions; cephalic and caudal portions were examined: The following results were obtained: 1) A single layer of undifferentiated cell was the primitive epidermis at the 4th week and it was followed by two layered epidermis consisting of periderm and primitive basal cell layer. Epidermal ridges started to develop along with primitive eccrine and hair germs as clustering of basal cells at the llth week. Stratum inter-medium was formed at the 12th week, and primitive granular cell layers and keratin formation in association with hair follicles at the 19th week forming earliest adult type epidermis, followed by progressive maturation. 2) The thickness of the fetal epidermis and keratin layer increased as the fetal age approached to the term with its slightly different developmental pattern by the site of body. Cephalic protions developed slightly earlier than the other parts. 3) The developmental pattern of various portions of epidermis could be categorized into three groups; (1) scalp, forehead and face; (2) chest, abdomen and back; (3) palm, sole, finger and toe.

The study presents the application of STR polymorphisms to male identification in the cases of a serial rapist in Korea. Since October 2000 a rapist from Cheongju city (a town located in central district) committed at least 36 rapes. DNA profiles obtained from semen stains, buccal cells and tongue tissue left at the scenes of crime and vaginal swabs of victims gave information that one and the same man had committed all the rapes. The Y-chromosome haplotype (12 loci) obtained was used for the identification process of rapist in mixed genotypes including victim's alleles. The crime scene data were referred from investigating police authorities described the relationship of victim to the offender, victim's age, time and place of sexual assault and rape locations. The behavioural analysis of crime scenes showed more similarities than differences for related crimes. These components were usually assessed in terms of proximity in time and space. Certain crime scene aspects of a serial rapist help identify components of offender spatial behaviour. As a result of this work, future research on the geography of rape and behavioural aspects of rapist will be directed towards those aspects of offences, which have been identified as relevant to the distance between an offender's base, and the site where he approached his victim.

A rare case of mucoid cyst of the penile skin in a 23 year-old man is reported, which has been presented as a movable, superficial and no tender nodule, measuring 0.8 cm in maximum diameter at the periurethral meatus of the glans for 6 months. This nodule was removed by simple excision and proved to be a mucoid cyst of penile skin, which was lined by pseudostratified columnar epithelium with occasional mucous epithelium and glands, suggesting its origin is most likely from sequestrated periurethral glands.

Sebaceous adenoma is a rare solitary or multiple yellow, circumscribed neoplasm consisting of sharply demarcated, proliferating lobules or irregular size and shape that are composed of three cell bypes: basal cells, mature and transitional sebaceous cells. We reported a case of extremely rare sebaceous adenoma arising in caruncle of the left eye in a 78-year-old female. A polypoid tumor nodule, measuring 0.6x0.5 cm, was noticed 6 months before resection. It was grayish white with granular surface. There is no evidence of associated visceral neoplasm. Histopathologically, it revealed a lobulated tumor, composed of equal amount of highly differentiated sebaceous and intermediate transitional epithelium with minor participation of basaloid cells. This tumor is thought to be the neoplasm of the sebaceous gland normaly present in the caruncle of the eye rather than ectopic origin.

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized histologically by massive infilteration of right ventricular wall by fat tissue with surviving strands of cardiomyocytes bordered by or embedded in fibrosis. ARVC has been recognized as a cause of sudden death, especially in the young. We report an autopy case of ARVD/C in a 35-year-old female. She was found dead in her house under apparently natural circumstances. The autopsy revealed a dilated 340-gram heart with a fibrofatty replacement of the right ventricular myocardium. On the review of her past medical history, she had taken medical examination for prolonged general weakness about 1 year prior to death. At that time the echocardiogram revealed dilatation of right ventricular cavity size and moderately decreased left ventricular systolic function, the electrocardiogram revealed R>S at V1 lead and T-wave inversion at V1-V3 leads. To the best of our knowledge, this is the second autopsy case of ARVD/C, reported in the literature of Korea.

We report a case of epidermolysis bullosa simplex occurred in a 12-year-old girl, who presented with intractable bullous lesions of the hands and feet after minor traumas ever since her early neonatal period. The bullous lesions were noted on the 2nd and 4th webs of the fingers and dorsum of the hands as well as on the skin of the ankle. The lesions were healed without scar formation. Family history was not contributary and seasonal pattern was not noted. Histologic sections revealed intraepidermal bullae just above the well preserved basement membrane. Electron microscopic findings revealed cytolysis of basal cells with preservation of the basement membrane, indicating the epidermal type of epidermolysis bullosa simplex.

Chronic rheumatic heart disease is the most important consequence of rheumatic fever and characterized principally by deforming fibrotic valvular disease(particularly mitral stenosis), which can produce permanent dysfunction and severe, sometimes fatal, cardiac dysfunction decades later. So the operation should be carried out in symptomatic patients with moderate to severe mitral or aortic stenosis or regurgitation. Postoperative mortality rate is low. But some postoperative complications including thromboembolism and prosthetic valve endocarditis are associated with high mortality. We report a autopsy case diagnosed as cerebral infarction due to thromboembolic complication of rheumatic heart disease patient with mechanical mitral and aortic prostheses. To our knowledge, this is the initial autopsy presentation of cerebral infarction due to thromboembolic complication of mechanical prosthetic valve in the patient with rheumatic heart disease in Korea.

The developing process of the hair of the fetal skin was studied. The ages of 103 human embryos and fetuses ranged from 4 to 40 gestation weeks. Ten different sites were selected, i.e., scalp, forehead, cheek, chest, abdomen, back, palm, sole, finger and toe. For the embryos 3 sites were studied, i.e., cephalic, trunk, and caudal portions. Following results were made: 1) The primitive hair germ was first noted the 10th week in the face skin as nubbins of mesenchymal cells beneath discrete foci of crowdes, elongated germinative epithelial cells. The developing hair germs and hair pegs were observes at the cephalic portion by 11 weeks. At 15 weeks the hair pegs including hair germs were noted in the trunk skin. The bulbous hair peg stage started at the 16th week in the cephalic portion and at the 18th week in the trunk. 2) Relative number of fetal hairs progressively increase up to 20 weeks of gestation but, thereafter decreased although it was different by the site of the body. 3) The diameter of fetal hair follicles increased with fetal age to the term with slight difference by the portion of body. 4) The developmental process of hair was more rapid in the cephalic portion than the trunk in views of morphologic changes of the hair structures, number and diameter of hair follicles.

Cardiovascular disease is the most important cause of unexpected sudden death. Although ischemic heart disease by coronary atherosclerosis is the most common cause of sudden cardiac death, other diseases such as cardiomyopathy, congenital heart disease, valvular heart disease and rarely myocarditis can produce sudden cardiac death. Myocarditis is an inflammatory process of the myocardium characterized by an interstitial inflammatory infiltrate and an injury to myocytes adjacent to the inflammatory cells. The clinical expression of myocarditis ranges from the asymptomatic state to fulminant fatal congestive heart failure. Because myocardial involvement is subclinical in most acute infectious disease, the majority of patients have no specific complaints referable to the cardiovascular system. It is possible that it causes a medicolegal problems in case of sudden death. Therefore, author reviewed the clinical and pathological findings of 18 myocarditis autopsy cases. The victims 'age was varied 4-month-59-year olds. 5 (28%) were male and 13 (72%) were female. 15 cases received medical treatment due to clinical symptoms(URI symptoms: 2 cases, tonsillitis and tonsillar abcess: 3 cases, GI symptoms: 5 cases, URI & GI symptoms: 3 cases, pneumonia: 1 case, operation due to ovarian tumor: 1 case) and were associated with medicolegal problem. By the results of this study, important gross findings were pericardial effusions, characteristic cardiomegaly, and pulmonary edema.
