We repart herein a case of psoriasifomi sarcoidosis. A histopathological examination reveaied sarcoidal ulomas throughout the dermis. There wa no systemic nvolvement, The skin lesions resolved aftier one month following treatment with low dose oral prednisolone. This is the first case of psoriasiform sarcoidosis in Korea.

Cutaneous metastasis from parotid gland carcinoma is very rare and there have been no re-ports in Korean literatures. Furthermore, it can often manifest as inflammatory type of skin metastasis and mimic a radiodermatitis. We report a case of a 31-year-old Korean man with cutaneous metastasis originated from parotid gland mucoepidermoid carcoinoma which mimicked clinically a radiodermatitis.

Neurocutaneous melanosis is a very rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign or malignant melanotic tumors of the central nervous system. We report herein a case of neurocutaneous melanosis with leptomeningeal melanosis and a malignant melanoma of the right temporal lobe in a 46-year old man. The case is exceptional as regards the late onset of symptoms and death. Even without a malignant melanoma, the symptomatic neurocutaneous melanosis has a fatal course. The syndrome is rare but lethal, so the dermatologist should be aware of this syndrome when evaluating the patients with large or numerous congenital melanocytic nevi so as to watch for the usual signs of increased intracranial pressure and to take prompt palliative measures.

We report a case of actinic granuloma in a 39 year-old woman who was presented with multiple anetoderma on non-sun exposed skin such as the neck, upper arms, elbows and calfs. The anetodermic presentation of actinic granuloma has never been reported and the common pathogenesis involving reduction of elastic fibers link the two disorders. Anetoderma secondary due to actinic granuloma should to be included in the list of secondary anetoderma and may suggest one of the possible pathogenesis of anetoderma.

Cutaneous pseudolymphoma (CPL) has a microscopic appearance that resembles that of cutaneous lymphoma, but shows a clinically benign course. The differential diagnosis of CPL with cutaneous lymphoma is very important because clinical outcomes of them are quite different. We herein describe two cases of B-cell pseudolymphoma, which were difficult to differentiate from cutaneous B-cell lymphlma. All of two cases, Polymerase chain reaction of immunoglobulin heavy chain gene rearrangement showed polyclonal pattern.

A 68-year-old Korean woman was consulted to the department of dermatology to evaluate ulcerated lesions on the perianal area, which developed about 3 weeks after a cadaveric renal trans-plantation. Histopathologic examination showed large atypical cytomegalic cells in the upper dermis. Polymerase chain reaction(PCR) study revealed positive cytomegalovirus(CMV) deoxyribonucleic acid(DNA) from the skin tissue. We herein present a case of cutaneous CMV infection presenting as perianal ulcers.

BACKGROUND: The clinical efficacy of oral isotretinoin in the treatment of severe acne is well established but there is no published data about the recurrence rate and the optimum dose for lowest recurrence in Korean patients. OBJECTIVE: The objective of this study was to determine the recurrence rate after one course of isotretinoin in oriental cases. METHODS: Sixty eight cases were available which fulfilled the inclusion criteria ; clearing af- l ter one course more than 10 weeks and at least two year follow-up thereafter. Isotretinoin was used with oral dosage 0.3-1 mg/kg/day (0.6±0.1) with duration from 10 to 46 weeks (19.7±6.2). RESULTS: Overall, 78% of patients had relapsed with most requiring topical antibiotic therapy only. In patients receiving more than 120 mg/kg, the percentage without recurrence was 75 % which was significantly higher (p<0.001) in comparison with only 15 % among patients receiving less than 120 mg/kg. Doses between 100 and 120 mg/kg were not as effective as those ones with more than 120 mg/kg for preventing recurrence. CONCLUSION: The results indicate that moderate doses of isotretinoin are well tolerated and pro-duce excellent clearing. However, in order to minimize recurrence rate, the optimum dose may be at least over 120 mg/kg of the cumulative dose which means more than 6 months of treatment in most of the Korean patients with acne.
