BACKGROUND: Androgenetic alopecia is considered to be a genetically determined disorder influenced by age and androgen. The proportion of patients with androgenetic alopecia among the total number of patients with alopecia seems to be gradually increasing. OBJECTIVES: The purpose of this study is to evaluate the family history,clinical and endocrine status of the patients with androgenetic alopecia. METHODS: 1113 patients with androgenetic alopecia who had visited the Department of Dermatology, Yongsan Hospital, College of Medicine,Chung-Ang University during the 3 years (1995.1-1998. 12) have been examined. RESULTS: The results are summarized as follows 1) The incidence of androgenetic alopecia among the total number of alopecia patients was 64.5%, showing recent increment. 2) There were 855 male and 258 female patients being most prevalent in the third decade in both sexes and the patients younger than 30 years old with premature androgenetic alopecia,made up 70.3% of the male patients and 48.8% of the female patients with androgenetic alopecia. 3) While Norwood's type Iia was the most common and following type II, III vertex,and IV in the male AGA, Ludwig's type II was the most common in female AGA 4) There was a family history of baldness in 53.5% of first degree relatives in male patients and 51.6%in female patients. 5)Associated diseases were observed in 565(66.8%) of the male patients and 219 (84.8%) of the female patients:diseases associated with androgen such as seborrheic dermatitis and acne vulgaris occupied 39.1%. CONCLUSION: Based on our findings, those who want to treat androgenetic alopecia at the earlier ages are gradually increasing and it seems to be reasonable to believe that the age, genetic factors, localized effects of androgens on the scalp and the density and/or functional activity of androgen receptors may influence the pathogenesis of androgenetic alopecia.

Multiple symmetric lipomatosis is a rare disease and affects almost exclusively middle aged man, usually with a background of excessive a alcohol intake. The disease is characterized by progressive growth of subcutaneous fat masses which are located symmetrically at neck, shoulders, chest, abdomen and groin, and which subsequently penetrate deeply into the surrounding spaces and structures with symptomatic compression of deep organs, such as trachea. A recent survey revealed a high incidence of sometic and autonomic neuropathy. The exact cause of the disease is not known, but a hyperplastic mechanism has been postulated, with in vitro studies demonstrating a defect in adrenergic-stimulated lipolysis of lipomatous tissue. We have experienced two cases of multiple symmetric lipomatosis. Case 1 was a 59-year-old male, complaining of slowly enlarging doughunt ring-shaped mass at his neck. He had a habit of excessive alcohol intake for many years. The subcutaneous mass at the neck was excised. The pathology report described the specimen as "normal adipose tissue". Case 2 was a 49-year-old male, complanining of slowly enlarging multiple symmetric masses at the neck, shoulders, chest, abdomen, flank and groin over a period of 6 years. He also complained of mild muscular weakness. He had a habit of excessive alcohol intake for many years. The subcutaneous mass in the neck was excised. The specimen had a tendency to form globular masses and microscopically indistinguishable from mature adipose tissue.

Tumor angiogenesis, the development of new blood vessels by tumor, is a widely observed phenomenon associated with the growth of human solid tumors. To investigate how tumor angiogenesis correlates with other prognostic features i.e. menopause status, tumor size, lymph node metastasis, mitosis, angioinvasion, estrogen receptor (ER), p53 protein expression, histologic grade and clinical stage, we counted microvessels by immunohistochemistry using antibody for CD34 antigen in 56 cases of invasive breast carcinoma (27 with and 29 without axillary lymph node metastases) and 20 cases of non-inflammatory benign breast lesion. CD34 antigen is expressed on the surface of hematopoietic progenitor cells and more sensitively expressed than factor VIII in vascular endothelial cells. Microvessel count (MVC) was performed at a single hot field of 200x magnification (0.74 mm2 per field). The results are summarized as follows; 1) The mean MVC of invasive carcinoma and benign breast lesion were 92.0+/-54.4 (range, 7-237) and 20.7+/-16.6 (range, 4-73), respectively (p<0.0001). 2) Although MVC had no correlation with all other prognostic factors i.e. menopause status, tumor size, lymph node metastasis, mitosis count, angioinvasion, ER, p53 protein expression, histologic grade, and clinical stage (p>0.05), MVC had a tendency to increase in tumors with axillary LN metastasis or without ER expression. 3) Without correlation with MVC, ER (+), angioinvasion (-) and higher histologic grade correlate to significantly higher mitosis count (p<0.0005). Also, angioinvasion correlate to a significantly higher histologic grade (p<0.05). In conclusion, angiogenesis is related to tumorigenesis, but MVC may not be related to other clinicopathologic factors.

An autopsy case of a newborn male who died of exsanguination into the subamniotic space of placenta presumably due to the rupture of the umbilical vein, is reported. This fetus, previously uneventful except for hydramnios and partial breech presentation showed obvious signs of fetal distrees during the first stage of labor that lasted for 6 hours to this 25 year old multigravid mother who came to the hospital because of labor pain at 29 weeks of gestation. Immediately after birth the baby was pale and the Apgar score was 1. He died 30 minutes after birth. Postmortem examination confirmed generalized pallor in this 1380 gm baby, with petechial hemorrhage of viscera and subarachnoid hemorrhage. No other findings of the cause of death were found. The placenta showed large ellipsoid subamniotic hematoma containing approximately 76 ml of blood, which is 57% of the total circulation blood volume of the fetus.

Mesenteric lymphadenitis due to Yersinia enterocolitica infection is not common in Korea. Although most cases of Yersinia enterocolitica-induced mesenteric adenitis are self limited, cardinal features of Yersinia enterocolitica-induced mesenteric adenitis are so similar to those of acute appendicitis that some of the patients undergo laparotomy with suspected appendicitis. The findings on laparotomy in such patients are usually enlarged mesenteric nodes with a normal or slightly inflamed appendix. Because histologic examination of the removed mesenteric lymph nodes reveals reactive hyperplasia in most cases, it is usually difficult to suspect Yersinia enterocolitica infection on morphology of the resected nodes. But suppurative granulomata of mesenteric lymph nodes, uncommonly encountered in Yersinia enterocolitica infection, strongly suggest yersinial infection. We report a case of mesenteric lymphadenitis in a 10-year-old boy, who underwent laparotomy with suspected acute appendicitis. The removed lymph node showed several suppurative granulomata in the cortex, suggesting yersinial infection. Serologic study confirmed Yersinia enterocolitica serotype O:3 infection.

Papillary serous peritoneal carcinoma(PSPC) is a rare malignancy that arises in the peritoneum and histologically resembles papillary serous carcinoma of the ovary. If peritoneal carcinomatosis occurs in the absence of an obvious primary tumor site and is associated with a papillary serous pathology, we may be dealing with the distinct entity of PSPC of extraovarian origin. Radiological findings suggesting the diagnosis are diffuse microcalcifications in the peritoneum, which occur in relation to psammoma bodies. The Ca-125 is most often abnormal and, not uncommonly, markedly elevated. The diagnosis requires that the surgeon identify grossly normal ovaries or minimal surface involvement. If PSPC is confirmed, a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and aggressive debulking surgery should be carried out, followed by cisplatin-based chemotherapy. We report a case of PSPC arising from the rectum in a 41 year-old woman.

Diffuse leiomyomatosis of the esophagus is a rare condition and usually extends from the mid-esophagus to the proximal third of the stomach. Macroscopically, there is a marked diffuse thickening of the esophageal wall, with or without nodularity, predominantly affecting the circular muscle coat. Microscopically, the disorder is characterized by the loss of the normal orientation of the smooth muscle fibers of all three layers. We report a case in a 37-year-old woman which was incidentally discovered at exploratory thoracotomy.
