Porencephaly is relatively rare condition defined by an defect or a defect or cavity in the cerebrum owing to a developmental malformation or to a destructive lesion. Fory-five porencephaly patients diagnosed by Brain CT were clinically analyzed and the following results were obtained. 1) By the age group presenting initial symptoms, the peak incidence was from 1 month to below 3 years old. 2) In initial symptoms, seizure, spastic weakness, headache were showed in order of frequency. But 7 cases (15.5%) were asymptomatic. 3) The latency of diagnosis after presenting initial symptoms from the symptom onset time to 10 years. 4) The subsequent symptoms were as follows: spastic weakness, speech disturbance, gait disturbance, mental retardation, sensory loss and seizure showed independently or combined. 5) As etiologic factor, 21 cases (46.7%) were congenital, 16 cases (35.5%) were post-traumatic or post-operative and 8 cases (17.8%) were perinatal. 6) The prognosis was seen various from mild to severe. Out of 45 cases, 29 cases (64.4%) were no complications. But the prognosis in patients with post-traumatic or postoperative etiological factors was poor. With the advent of brain CT and the resultant capability of detecting structural defect and cerebral lesions responsible for epilepsy or focal neurologic signs, porencephaly was seen to be readily recongizable by CT examination. Since porencephaly is a significant contributor to the spectrum of CNS lesion and benign condition, ist recognition is important in determining prognosis and therapy.

Erythrasma is a chronic, superficial bacterial skin infection involving the body folds and toewebs, and sametimes it may be generalized. The causative organism of this disease is Corynebacterium minutissimum. But, in Korea, there are few reported case about this common condition. We experienced a case of erythrasma on 39-year-old male who have had well defined, brownish fine scaly patches on both crural areas for 15 years. We had treated this patient with topical antifungal agent for 1 month under impression of tinea cruris, But skin lesion was not improved. So, we reexamined the lesion and diagnosed it as genitocrural form of erythrasma with it's clinical appearance, red fluorescence under Wood's light. And we treated it with oral erythromycin.

Actinic reticuloid as a manifestation of chronic actinic dermatitis (CAD) is a rare dermatosis whose clinical and histologic features resemble other types of pseudolymphomas including mycosis fungoides and Jessner's lymphocytic infiltration, and it is regarded as an eventual stage of various photodermatoses like photosensitive eczema or persistent light reaction or chronic photoallergic contact dermatitis and so on. Phototests in the patients with actinic reticuloid usually reveal hypersensitivity to UVB, UVA, and sometimes to visible light. We present a case of actinic reticuloid in a 65-year-old male, whose skin lesions developed as erythematous lichenified infiltrating plaques on the face at first, and then spread themselves onto the upper trunk later. Histologically those skin lesions showed the aggregation of atypical lymphocytes and photobiologically the results of phototests revealed photosensitivity to UVB and UVA.

Papillary tumor of the temporal bone or middle ear has been recognized as an aggressive neoplasm because of its invasive growth pattern. The site of origin is controversial so that most cases have been reported under various diagnostic terms. Recently, Heffner(1989) suggested that the endolymphatic sac is a possible site of origin, because the tumor resembles the endolymphatic sac in several aspects. We report two such cases. One patient was a 34-year-old female presenting with tinnitus and hearing difficulty for 1 year. Temporal bone CT revealed extensive bone destruction by the tumor which was located in the posterolateral aspect of temporal bone. The other patient was a 56-year-old female who complained of tinnitus, dizziness and otalgia for 2 years. Cranial MR imaging showed an irregularly marginated mass in the left jugular fossa with extension to the petrous bone. Histologically, both cases showed a papillary pattern and locally destructive growth that are typical of papillary tumor of the endolymphatic sac. The papillae were lined by a single layer of bland-looking cuboidal to low columnar cells. Immunohistochemically the lining cells expressed cytokeratin, epithelial membrane antigen, neuron specific antigen and in one case, S-100 protein, supporting the thesis that these neoplasms might be of endolymphatic sac origin.

Acropustulosis of infancy is an uncommon, but not rare syndrome established as a new disease entity by Kahn and Rywlin(1976), which is characterized by recurrent, intensely pruritic vesicopustules on the distal extremities. We'd like to report a case of acropustulosis of infancy. Our patient was 19 month old girl who had been suffering from her skin disease since the age of 12 months. Intensely pruritic, 1 to 2 mm vesicopustules erupted on the palms, soles and the ventral aspects of the fingers. There were no bacteria, fungus and parasites(Sarcoptes scabiei) on the pustular lesions. Histopathologically, biopsy specimen of the left sole revealed large, well circumscribed intraepidermal pustule which was filled wth polymorphonuclear leukocytes. We confirmed our case as typical case of acropustulosis of infancy by it's characteristic clinical features and histopathologic findings. Severity of the skin lesions seems closely related to the dosage of dapsone. The eruptions were unresponsive to topical steroid, antibiotics and antihistaminics. But we observed that dapsone has dose dependent relationship with acropustulosis of infancy.

Psoriasis is merely recognized as a disorder associated with pruritus. But in some cases, psoriasis does induce pruritus which could alter the daily lives of the people affected. Pruritus in psoriasis has been reported to be influenced by various external and internal factors and as a consequence, aggravation of psoriasis is possible by scratching due to the well-known Koebners phenomenen. Lichen amyloidosis, on the other hand, appears as multiple papules with intense pruritus. Recently, there are some evidence emphasizing pruritus as a main factor in forming amyloid deposits. We report a case of 65-year-old lady who was suffering psoriasis for 25 years with associated pruritic papular lesions on both of her thighs, knees and ankles. The diagnosis of Lichen amyloidosis was confirmed by Periodic Acid Schiff and Dylon stain. We discuss the role of pruritus in lichen amyloidosis and psoriasis and speculate that pruritus induced by lichen amyloidosis may induce a vicious cycle in aggravating psoriasis.

BACKGROUND: Psoriasis is a chronic relapsing disorder which is influenced by various external factors. A study involving a large number of patients with objective assessment methods may help us to elucidate correlations between external factors and the course of psoriasis. OBJECTIVE: Our purpose was to investigate the basic demographic data of psoriasis in a large number of Korean patients and to correlate disease activity, area of involvement with various external factors known to improve or worsen psoriasis. METHODS: Epidemiological and clinical data with particular reference to the extent and activity of the condition in 1,600 psoriasis patients between 1982 and 1998 were collected and analysed. RESULTS: 1. Patients in their twenties were most common(28.7%). There were no sexual predominance in our patients. 2. With reference to the extent of this skin condition, 43.4% of patients were mild cases, 38.3% were moderate and 18.3% were severe. 3. With reference to the activity, 42.9% of patients were mild cases, 26.5% were moderate and 30.6% were severe. 4. The most common morphological features were nummular types(55.8%), followed by large plaque types(23.4%) and guttate types(14.5%). 5. 57% of patients experienced a11eviation of their lesions in summer while 65% of patients experienced aggravation in winter. 6. 55% of the patients experienced improvement of their lesions in sunlight exposure whereas 7% of the remainder experienced aggravation. 7. 64% of the patients replied that their lesions tend to aggravate after a stressful event. 8. Among those who experienced pregnancy, 40% replied that their lesions improved while being pregnant. On the other hand, 19% experienced aggravation. 9. Severe forms were overwhelming in large plaque types in relation to extent and activity (p<0.05). 10. Among the external factors investigated, stress showed statistically signficant association with the severity of psoriasis classified by extent and severity(p<0.05). CONCLUSION: We investigated the epidemiological and clinical features of psoriasis in a large number of Korean patients in relation to various external factors. The condition in more than half of the patients was moderate or severe with reference to the extent and activity. Among external factors, stress seemed to have significant correlations with increased frequency in severe psoriasis patients.

BACKGROUND: Narrow-band UVB phototherapy using 311+-2nm wavelength is in widespread use due to its greater efficacy and, possibly, safety compared with broad-band UVB sources. OBJECTIVE: We performed emollient narrow-band UVB(NBUVB) phototherapy to evaluate the clinical efficacy and safety in Korean psoriasis patients. METHODS: Fifteen psoriasis patients received narrow-band UVB phototherapy. We categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy, and measured the PASI score every two weeks. RESULTS: 1. Among patients who received narrow-band UVB phototherapy, clearing was shown in 40.0% and improvement in 27.7%, and failure in 33.3%. 2. The total number, duration, final and cumulative doses to achieve grade IV were 16.3, 39 days, 1,050mJ/cm2 and 12,125mJ/cm2 respectively. 3. There were some side effects of NBUVB phototherapy such as pruritus(53.3%) and mild burning(13.3%). CONCLUSION: Narrow-band UVB phototherapy is a effective treatment modality which is convenient and less erythemogenic in psoriasis. It will be used more and more and play an important role in the treatment of psoriasis.
