We observed a case of sebaceous epithelioma associated with a nevus sebaceus in a 25-year-old male. The tumor was bean-sized, dome-shaped nodule on the slightly yellowish plaque of nevus sebaceus. Histopathological finding shows undifferentiated cells which are arranged in a palisade fashion at the periphery of a cell mass and a fairly large number of transitional cells and groups of mature sebaeeous cells.

Almost all cases of acute methanol intoxication result from ingestion. Absorption of methanol following oral administration is rapid and peak concentration occurs within 30-60 min. Foromic acid converted metabolites of methanol are responsible for its toxic effect. Methanol poisoning typically induces nausea, vomiting, abdominal pain, and mild central nervous system depression. Then there is a latent period lasting, followed by an uncompensated metabolic acidosis and visual dysfunction, depending on the dose of methanol ingested. Here we report on three patients who were victims of methanol intoxication due to ingestion of windshield washer fluid, which was misidentified as an alcoholic beverage. One patient had a mild form, which included abdominal discomfort, another patient had a moderate case, which included nausea, vomiting, and acidosis, and the other patient had severe acidosis and altered mentality and visual dysfunction. Except one case of visual dysfunction, all three patients recovered successfully following medical treatment and hemodialysis.

An apocrine hydrocystoma is a translucent cystic nodule that looks like adenomatous cystic proliferation of an apocrine gland, which originated from a hair germ. Dermoid cyst is a cystic teratoma that contains developmentally mature skin appendages, such as hair follicles, sweat glands, and other tissues derived from the ectoderm. Many investigators believe that dermoid cysts re originated from the ectoderm, specifically the hair germ cells. A 58-year-old woman was presented with a purple, asymptomatic, dome-shaped nodule on her right lower eyelid that had been slowly increasing in size for several years. Histopathological examination revealed two well-demarcated cysts: one was lined with stratified squamous epithelium with mature hair and sebaceous glands and the other contained large cystic spaces, which papillary projections extended. We report a rare case of a dermoid cyst, combined with an apocrine hydrocystoma, occurring in the right lower eyelid.

Chronic graft-versus-host disease (GVHD) usually presents 100 days after allogenic bone marrow transplantation. Chronic GVHD cutaneous lesions are characterized by lichenoid or sclerodermoid variants. Vesicles, a common presentation in patients with acute GVHD, rarely appear in chronic GVHD. We report a case of a 49-year-old man who presented with bilateral vesicles on lower extremities. He was diagnosed with myelodysplastic syndrome 2 years before and was taking oral cyclosporine after the allogenic bone marrow transplantation. Six months post-transplantation, lichenoid and sclerodermoid lesions developed on his entire body and he was diagnosed with chronic GVHD and eosinophilic fasciitis. A biopsy of the vesicles revealed detached lower margins of the epidermis, necrotized keratinocytes, and infiltration of lymphocytic inflammatory cells. Administration of oral prednisolone alleviated the patient's symptoms. This is an interesting case showing a new pattern of vesicle appearance after development of typical chronic GVHD lesions.

Pyogenic granuloma is one of the common benign vascular tumors of infants and children and it can also occur in adults. There are 25 reports of patients with pyogenic granuloma in the Korean medical literature. In three reports, giant pyogenic granuloma developed over 2 cm in size (1.3 x 0.7 cm, 1.2 x 0.8 cm and 1.1 x 0.7 cm, respectively). There have been no reports in the Korean medical literature of pyogenic granuloma over 2 cm in size. Herein, we report on a giant pyogenic granuloma on the palm of a 72-year old female. The lesion was of an unusually large size of 2.8 x 2.5 x 1.3 cm and we excised it by performing electrosurgery.

Ectopic ossification refers to the process of new bone formation in sites that normally do not ossify. The auricle is composed of elastic cartilage, and hence is a pliable structure. Auricular ossification is a rare condition that might be caused by injurious processes, including frostbite, physical trauma, and inflammation as well as processes related to metabolic or endocrine disorders. Here, we report a case of unilateral auricular ossification in a 53-year-old Korean man who had previously rubbed his ear repeatedly with his hand.

Erosive adenomatosis of the nipple is a rare, benign neoplasm, currently thought to originate from the terminal lactiferous ducts and subareolar breast tissue. Clinically, erosive adenomatosis of the nipple is often indistinguishable from that of mammary Paget's disease, and it could be misdiagnosed as intraductal carcinoma as it has a similar histological finding. We present the case of a 36-year-old woman who had a unilateral erythematous induration of the nipple that contained a palpable, firm nodule. It had first been noticed 2 years earlier. The surface was occasionally crusted, and there was a bloody discharge. Histopathological examination showed irregular, dilated tubular structures, which were lined by a peripheral layer of cuboidal cells and a luminal layer of the columnar cells that demonstrated decapitation secretion at their luminal border.

Pericardial defect is a rare congenital cardiac disorder. Most patients were asymptomatic but some patients with partial pericardial defect occasionally complain acute symptoms such as angina, syncope, rarely sudden cardiac death. So, differential diagnosis with other ischemic or structural heart disease is crucial in the management of such patients. But there is no consistently successful diagnostic method. In the past, artificial diagnostic pneumothorax was used to document the absence of pericardium. However, it is not easily accepted due to excess morbidity and failure rate. Recently, echocardiography and more often, computed tomography, magnetic resonance imaging are used to confirm the diagnosis. We experienced a 52 years old male patient with atypical chest pain, who was diagnosed as complete left pericardial defect with computed tomography.

A 67-Year-old male patient was adimitted due to aggravation of long-standing left moter weakness. Past history revealed weakness of left extremity for 20 years caused by CVD attack. On adimission, his mental state was drowsy and brain CT scan showed a round mass mimicking a brain tumor in the frontal horn of right lateral ventricle with asymmetric dilatation of lateral ventricles. After failed carotid angiography due to vascular tortuosity, his mental state was progressively deteriorated and left hemiparesis aggravated. A right external ventricular drainage was done, and 5 days later a craniotomy was performed under the impression of the intraventricular tumor causing obstruction of right foramen of Monro, but a large thrombosed aneurysmal sac was found intraoperatively. Retrial of carotid angiography revealed a large anterior communicating artery aneurysm. After second operation, maningoencephalitis with wound infection was complicated. Twenty days after second operation, clipping of the aneurysmal neck with removal of partially thrombosed aneurysmal sac was performed successfully.

The familial environment may also play an important role in the epidemiology of HCV infection through vertical and horizontal transmission by infected household members. However, it is still controversial whether familial clustering of HCV occurs. We experienced a case of familial clustering of hepatitis C virus. A 10-year old girl presented with nausea, vomiting and anorexia for a month was diagnosed as hepatitis C. Her mother, grandmother, a maternal aunt and her daughter had contracted with HCV. Her laboratory findings showed AST/ALT 63/122 IU/L, positive anti-HCV Ab and HCV RNA (3.54 x 10(5) copies/mL). Pathologic findings of the liver biopsy revealed chronic hepatitis with minimal lobular activity, mild porto-periportal activity and mild portal fibrosis. After treatment with interferon-alpha 2b for 6 months, the clinical symptoms and laboratory findings were normalized.
