Basal cell carcinoma(BCC) and squamous cell carcinoma (SCC) are very prevalent neoplasms of the human skin. Ultraviolet radiation in sunlight is a well-established mutagen of the p53 gene and is one of basal cell carcinoma and squamous cell carcinoma. The newly-formed vascular network is important for neoplasms to grow beyond a size of about 1 mm2. Recent reports have suggested the hypothesis that a mutant p53 protein is closely related with capillary density. Immumohistochemistry for p53 protein and CD34 was performed in 20 cases of BCCs and 14 SCCs to evaluated the relationship between p53 protein and capillary density. The results were as follows:1. The microvessels stained by CD34 were mainly located in the interface of tumor cells and stroma. 2. There was no difference in the microvessel density according to the histologic types and age of the patients, but a higher microvessel density was noted in male patients. 3. The aggressive BCCs and the less-differentiated SCCs showed higher p53 immunostaining. 4. The mean microvessel density of cases showing strong positive immunostaining of the p53 gene(54.73+/-17.75) was higher than that of others(39.75+/-18.30). These results suggested that p53 protein expression and microvessel density are not related to the histologic types and age of the patients, but that differentiation and biologic behavior such as the infiltrating property of tumors and the microvessel density are closely related to p53 protein expression.

An endodermal sinus tumor is a malignant germ cell tumor that usually arises in the gonads, but on rare occasion occurs in extragonadal locations. Our case was that of a 3 year old girl who complained of a rapid growing orbital mass. On histologic examination it revealed the typical picture of an endodermal sinus tumor and it also disclosed a positive reaction for alphafetoprotein using an immunoperoxidase technique. An orbital exenteration was performed followed by chemotheraphy, but the patient died 5 months after the onset of the disease.

Dermal melanocytosis is histologically characterized by the presence of ectopic melanocytes in the dermis. Mongolian spots, nevus of Ota, nevus of Ito and blue nevus are the most common types and these are usually present at birth or in early childhood. However, it has been reported that several types of dermal melanocytosis could appear in adult life. We report here on an unusual case of acquired dermal melanocytosis occurring in a 51 year-old female. She had bilaterall brownish or slate-bluish pigmented patches on the face and the posterior auricular, supraclavicular, scapular and back areas. The skin biopsy specimen taken from the upper back revealed scattered, darkly pigmented, spindle-shaped cells and dendritic cells containing abundant golden brown pigment in the dermis.

Yakovlev demonstrated that the Schizencephalies appear to result from injury to developing cerebral vesicles in the second month of intrauterine life. There is a total loss of neurons in restricted symmetrical zones of each developing hemisphere and on either side of the resulting cleft-shaped defects are evidences of subtotal injury to developing neuroblasts. A case of a 4 years old male with Schizencephaly is reported.

BACKGROUND: Limited information about the effects of stroke on sexual functioning is available. The purpose of this study was to assess the influences of ischemic stroke on sexual functioning and to evaluate the clinical and psychological factors related to poststroke sexual dysfunctions. METHODS:Sixty-six male post-ischemic stroke patients and fifty-one age-matched healthy controls completed a self-administered questionnaire on sexual functioning. The localization of ischemic stroke was determined by neuroimaging findings as well as focal neurological signs. The degree of disability and the degree of depression were also assessed. RESULTS: All domains of sexual functioning, including erectile functions, orgas-mic functions, sexual desire, intercourse satisfaction, and overall satisfaction were decreased in poststroke patients. Patients with occipital lesions had a lesser degree of sexual dysfunctions than those with lesions affecting other areas (p<0.05). Also, sexual dysfunctions in stroke patients were related to the degree of physical disability and the presence of depression (p<0.05). CONCLUSIONS Sexual dysfunctions are common in stroke patients. The reasons for sexual dysfunc-tions after stroke are multifaceted, which include stroke lesion site, physiological factors, and psychosocial factors. (J Korean Neurol Assoc 19(4):342~348, 2001)

Despite improvements in surgical technique, immunosuppressive therapy, and follow-up care, a considerable number of patients with kidney transplants die as a consequence of sepsis and throm-boembolism. The incidence of thromboembolism is higher in patients older than 40 years of age. Prominent among these is an increased incidence of acute myocardial infarction(AMI) in patients receiving corticosteroids. We encountered a rare case that septic shock due to artificial abortion, ARF, and DIC complicated by AMI. A 25-year-old female complained of fever, and watery diarrhea. She was emmergently admitted due to shock. Physical examination demonstrated hypotension and fever. WBC count was 45,300/mL. Elevated FDP, D dimer, CK with dominance of the MB isoenzyme, and troponin-I. EKG showed ST segment elevation in leads aVF, V3-V6. She was treated with cefuroxime, netilmycin, and dalteparin. Cultures obtained from the sputum, urine, and blood did not yield any microorganisms. Although sepsis could not be confirmed, sepsis was highly suspected from the clinical features. This is a rare case in which septic shock, ARF, and DIC complicated by AMI in a young female renal allograft patient. Since AMI in the absence of underlying conditions has been rarely described, we wish to bring attention to the diagnosis of this disorder in a young female allograft recipient and without any other predisposing abnormality.

Trichoblastoma is a benign cutaneous neoplasm that consists of follicular germinative cells. There have only been a few case reports describing the malignant counterpart of trichoblastoma. We report trichoblastic neoplasms that show histological features of malignancy. The histological sections revealed locally aggressive neoplasms showing prominent differentiation towards hair germ and follicular sheath with formation of papillary mesenchymal bodies and follicular bulb-like structures. The tumor was widely excised with a clear margin. No sign of recurrence has been noted 1 year later.

BACKGROUND: Acute diffuse alopecia areata (AA) was described as a unique AA which mimics anagen effluvium, or in which the initial hair loss is diffuse and followed by total denudation of scalp within several weeks or months. In spite of its peculiar clinical feature, there was neither further characterization nor known effective treatment for this form of AA. OBJECTIVE: To evaluate the characteristic clinical findings of acute diffuse AA and confirm the effect of high dose methyl prednisolone therapy. METHODS: The medical records of 13 patients with acute diffuse AA between January 2002 and April 2006 at the Department of Dermatology, Chungnam National University Hospital were reviewed. All patients were treated with high dose methylprednisolone therapy. RESULTS: Of the 13 patients who completed the study, 8 patients (61.5%) were male and 5 patients (38.5%) were female. The mean age was 29.6 years old. The progress of hair loss stopped 2.4 weeks on average after initial treatment and newly emerging hairs were recognized 4.1 weeks on average after initial treatment. 84.6% (11/13) of patients showed terminal hair growth, and 46.2% (6/13) of patients completely responded to this therapy. CONCLUSION: Acute diffuse alopecia areata can occur in male as well as in female patients. High dose methylprednisolone therapy appears to be effective in patients with rapidly progressing acute diffuse alopecia areata to prevent the progression of the disease.

Skin lesions can sometimes be the presenting sign of metastatic cancers. We report a case of skin metastasis resembling pyogenic granuloma from hepatocellular carcinoma, which is a common malignancy in Korea. A 79-year-old male presented with a 1 month history of a dark-reddish nodule on his left cheek, which was thought to be pyogenic granuloma. On histopathologic examination, it was composed of tumor cells and intervening sinusoids and therefore showed characteristics of hepatocellular carcinoma. We confirmed hepatocellular carcinoma upon abdomen computer tomography. We present this case along with a review of previous reports of cutaneous metastasis from hepatocellular carcinoma.
