The solitary type of Koratoacanthoma is a common, rapidly growing, benign tumor with a natural history of spontaneous involution which was first described by Hutchinson in 1889. It was well known that this Keratoacanthoma is close resemblence to squamous cell carcinoma clinicallt & histopathology. The etiology of Kertoacanthoma is ucertain but it have been associated with many exogenous factors, including sun exposure, occupational exposure to heat and trauma, and tar and with autoimmune etiology and viral infection. We experienced 2 cases of soitary type of Keratoacantoma with typical clinical and histopathologic findings which presented on the pubic area and forehead but had no predisposing factors of Keratoacanthoma. The one was 66-year-old woman who had been a history of proritic, rapidly growing tumor on Mons Pubis since about 6 months ago. The another one was 40 year-old male who had been a history of asymromatic, growing tomor on forehead since about 3 months ago. In the H-E stained sections, there were horn filled invagination, dyskeratotic cell, horn pearl in the epidermis and an inflammatory infiltration in dermis. Diagnosis was cinfirmedby the clinical and histopatholigical pictures. The former was treated by electrocautery after simple excision and the latter by curretage and electrodesiccation.

Malignant melanoma is a tumor arising within the melanocyte system of the skin, eyes and juxtacutaneous mucous membrane. Tbrough the lymphatic channel developed early metastasis and regional lymphade- nopzthy developed. Malignant melanoma may arise on apparently normal skin, in a junction nevua, rareh in a compound nevus and extremeIy rarely in an intradermaI nevus and 20% of total incidence of malignant melanoma are preceded by a nevocellular nevus. A 41 year-old male patient who had multiple, pea to walnut sized, black colored. nodules developing on entire body visited our Dermto. dept. About one year ago, solitary black colored nodule arose from preexisting pigmented nevus which had been from 20 yrs ago on Rt. ant. axillary area and then nodule remcved by wide exeision and regional lymphadenectomy at a Hosp. 2 months after surgical operation, multiple pea to walnut sized, black colored nodules has developed on entire body. There was no lymphadenopathy on entire body. In H-E & Fontana-Masson stain, numerous bizzarre large cells with hyperchromatic variable sized melanin pigments are seen in the dermis and subcutaneous tissues Mitotic figutes are present. Diagnosis was confirmed by the clinical and histological feature. The patient was treated with BCG waccination(4*10^6-8*10^6 live organisms weekly) by altemately intralesional inj, on the lesion and subcuraneous inj. on both shoulder during 6wks and has been in follow-up.

Tuberculosis of the skin may present clinically as plaques, ulcers, verrucous, lesions, nodules, tumors, vegetatives reactions, and cicartricial infiltration. The reaction of the host to the presence of Mycobacterium tuberculosis also varies with the extent and the degree of invasion, the virulence of the bacilli, and nonspecific factors such as age and generaI state of health. The incidence of cutaneous tuberculosis has tendency to decline in the world because of thc availability of effective antiTB drugs, elimination of infected milk herbs, and an elevation of living standards, but in Korea, cutaneous tuberculosis remained to be a significant medical problem. We experienced 21 year-old male who had a case of 3 clinical types including Lupus vulgaris, Scrofuloderma, Papulonecrotic tuberculid. Diagnosis of 3 clinical types vere established by clinical history and signs, histo pathology, tuberculin test and effective of treatment vith INH, streptomycin and literature were reviewed.

Developmental venous anomalies are congenital anomalies of the intracranial venous drainage and clinically asymptomatic. Cavernous hemangiomas are vascular malformations composed of dilated vascular channels lined with a single layer of endothelial cells without any intervening normal neural tissue. Although, cavernous hemangioma may be clinically silent, but frequently cause variable neurologic manifestations; intracranial hemorrhage, seizures, and focal neurologic deficits. Frequent association of these two diseases has already been reported and it has been suggested that cavernous hemangiomas not the developmental venous anomalies that cause the acute clinical symptoms. A 4 year old girl with sudden onset of headache, vomiting, gait disturbance and signs of unilateral cerebellar dysfunction 2 days before admission showed a 2.5x2.5cm sized hematoma with heterogenous signal intensity both in CT and MRI in the left cerebellar hemisphere. Four-vessel cerebral angiography revealed characteristic findings of developmental venous anomalies. Pathologic findings of the surgically removed hematoma disclosed typical feature of cavernous hemangioma. Based on the findings in this case and review of the literatures, we concluded that the possibility of other diseases such as cavernous hemangiomas must be considered in patients who has intracranial hemorrhage due to the developmental venous anomalies.

Pagets disease is charaterized by a unilateral sharply defined eczema with or without an underlying ductal adenocarcinoma of the female nipple which was described by James Paget on 1874. We experienced 2 cases of Pagets disease confined to the nipple & areola with or without a palpable mass. The one was 44-year-old female, who had been suffered from pea. sized, eczematous lesion and crust formation on the Lt. nipple and areola with a painful palpable mass in the Lt, breast and nipple retraction since about 3years ago(Fig. 1). The another one was 52-year-old female, who had been suffered frorn palm sized, same lesions of the former on the Lt. breast with accompanying itching sensation and without a palpable mass and nipple retraction since about 7years ago(Fig. 5). Histopathologically, there were large, round, clear staining cells with Iarge nuclei in the epidersi and an inflammatory infiltration in the dermis. Diagnosis was confirmed by the clinical and histological pictures. The former was treated by simple mastectomy and the latter by radical mastectorny.

BACKGROUND: We designed this double-blind, placebo-controlled study to compare the efficacy of remifentanil in reducing the pain of both propofol and rocuronium injection during rapid-sequence induction. METHODS: Ninety-five patients, scheduled for elective surgery under general anesthesia, were divided into 3 groups: saline (Group S, n = 31), remifentanil 1 microg/kg (Group R, n = 32), and lidocaine 1.5 mg/kg (Group L, n = 32) were administered after tourniquet application. The occlusion was released after 1 min and 5 ml of 1% propofol was injected over 10 s. Pain on propofol injection was evaluated by a 10-point verbal numeric rating scale (VNRS). The rest of the induction dose of propofol and 1 mg/kg of rocuronium, were injected. Pain on rocuronium injection was evaluated by a four-point score (FPS). RESULTS: The VNRS of propofol injection was as follows: R (0.78) = L (1.34) < S (4.26). The incidence of withdrawal response due to rocuronium was as follows: R (6.3%) < L (53.1%) < S (83.9%). The FPS of rocuronium injection was as follows: R (0.81) < L (1.78) < S (2.93). CONCLUSIONS: Pretreatment with a bolus of remifentanil was effective in simultaneously reducing injection pain of propofol and rocuronium. In addition, remifentanil pretreatment was more effective in suppression of withdrawal response by rocuronium than lidocaine.

Staphylococcus epidermidis is a normal inhabitant of skin, throat, mouth, vagina, and urethra. It is not usually pathogenic, particularly in immunocompetent hosts. This report describes a case of a pyogenic liver abscess caused by Staphylococcus epidermidis in a healthy 12-year-old boy. He was admitted to Seoul St. Mary's Hospital with intermittent fever for 6 days. Findings on abdominal computed tomography (CT) showed a mass measuring 7.0x6.5 cm in the right hepatic lobe. Culture of the abscess resulted in growth of Staphylococcus epidermidis as a causative organism. The patient was successfully treated with intravenous administration of antibiotics and percutaneous drainage of the abscess.

Tatbion is a tripeptide, reduced form of Glutathione(GSH or p-glutamyl-cysteiny1 -glycine). Glutathione(SH compound)is believed to inhibit melanin formation by combining witb the copper in tyrnsinase whicb is essential in the conversion of tyrosine to DOPA (3, 4-dihydroxyphenylalanine) and DOPA to DOPA-quinone or by forming cornplex with the intermediate in the tyrosine-to-melaa.in reaction. The effect of Tathion in the treatment of melasma has not been reported in Korea. We have observed the effect of Tatbion in 150 patients with melasma. After the average duration of Gwks of treatment(50-100mg tree tirnes/daily), we were abIe to grade the results as follow. Excellent(Pigmentation almost disappeared): 17. 4 % Good (Pigmentation markedly improved): 56. 7% Fair (Pigmentation slightly improved: 7. 3% None (No effect) : 18.6% The result showed relatively good effects of Tathion in the treatment of 122pts (81.4%) with melasma in total. The brief review of literature on the treatment of melasma was undertaken.

The clinical and pathological features of a paraganglioma arising in the cauda equina is described and compared with previous reports. The right microscopic fetures were similar to those of paragangliomas from other sites, with a 'Zellballen' pattern of cells containing arzyrophil granules. Immunohistocytochemical stains for neurone specific enolase, S-100 protein, cytokeratin were positive, but stains for glial fibrillary acidic protein were negative. Electron microscopy showed densely staining membrane-bound granules, cilia like structures and fibros bodies in the cytoplasm. The last two features only occur in paragangliomas from this site. The pathological findings suggest that paragangliomas in this site arise from pre-existing paraganglia, possibly of the visceral autonomic group.
