A Case of Infiltrating Lipoma Combined with Nevus Lipomatosus Cutaneous Superficialis / 대한피부과학회지

Infiltrating lipoma is one of the most deep-seated benign soft tissue tumor which occupies less than 1% in lipomas. There are two different types of infiltrating lipoma, one intramuscular lipoma, and the other intermuscular lipoma. Nevus lipomatosus cutaneous superficialis is a very rare skin disease which is characterized by the ectopic presence of mature adipose tissue in the dermis. In this disease two clinical types are distinguished: The first classic type is the multiple lesions of zonal distribution usually on the buttocks or on the lower back area. The second type is the solitary papule or nodule with less restricted tendency in its distrubution. We described a 31-year-old man who had a relatively well-defined localized, skin colored, 20x20cm sized, subcutaneous mass partially covered with brown colored papules and plaque on the left subscapular area. The skin lesion began about 11 years ago with brown colored papules and gradually increased in size to 20x20cm mass. Histopathological and clinical findings showed ectopic fat lobules consisted of almost mature cells in the dermis, between the each muscle fibers, and each muscle bundles.

A Case of Linear IgA Bullous Dermatosis of Childhood / 대한피부과학회지

Linear IgA bullous dermatoses(LABD) occurring in childhood is considered to be a childhood counterpart of LABD,rather than chronic bullous dermatosis of childhood. This disease characteristically involves the perioral area,lower trunk,pelvic region and the lower extremities. Immunopathologically,it is characterized by the linear deposits of IgA at the dermoepidermal junction of the perilesional skin. A 20-month-old female infant presented with multiple pruritic tense bullae on the face, lower trunk, both extremities and pelvic region of 2 weeks duration. She had no oral lesions or any specific signs or symptoms referable to the disease of the gastrointestinal tract. A skin biopsy revealed subepidermal blisters infiltrated with many neutrophils and a few eosinophils. Direct immunofluorescence demonstrated linear deposition of IgA at the dermoepidermal junction. An indirect immunofluorescence study using NaC1-split skin as the substrate revealed fluorescence for IgA in a linear pattern on the roof of the split at a titer of 1:40. The clinical diagnosis of LABD of childhood was confirmed and we started with a combined remedy of dapsone and corticosteroids; 10 weeks later almost all of the lesions had disappeared.

Pigmented Photoallergic Contact Dermatitis Due to Musk Ambrette / 대한피부과학회지

Pigmented photoallergic contact dermatitis is a disease usually resulting from recurrent cutaneous exposure to cosmetic photoallergens which produce bizarre dark brown hyperpigmentation. Histologicnl examination of this condition reveals liquefaction of the basal cells of the epidmis and melanophages in the upper dermis. A 50-year-female developed dark brownish mottled hyperpigmented patches on her face after using a soap named O.E. and taking a nap every afternoon for 4 years. The histological fmding on the lesion site was consistent with pigmented photoallergic contact dermatitis. The cosmetic photopatch test with, O.E. soap, and the Scandinavian scries resulted in a positive reaction only on one side where 5 J/cm2 lights were applied by using Waldman 800UV machine. The other side howed a negative finding. We fmally diagnosed pigmented photoallergic contact dermatitis based on the patients histoty of using the soap containing musk ambrette, a histological examination of a biopsy and the results of photopatch tests. We report rare case of pigmented photoallergic contact dermatitis.

Clinical Study and Skin Tests of Patients with Drug Eruption / 대한피부과학회지

BACKGROUND: Although drug eruption refers to a common dermatologieal condition, there are numerous setbacks in the diagnosis. In addition there are no annual average prevalence rates of drug eruptions according to time sequence in Korea. OBJECTIVE: This study attempts to detme the clinical features and causative drugs of drug eruptions, the diagnostic value of various skin tests and to evaluate the dome,stic annual average prevalence rate of drug eruptions according to time sequence. METHOD: 270 patients with drug eruptions were reviewed clinically. In 103 patients, intradennal, patch and scratch-patch tests were performed using suspected drugs. The annual average prevalence rate of drug eruptions was calculated from 10 different general hositals in Korea. RESULT: Exanthematous eruptions(49.3), fixed drug eruptions(30.1), and urticaria(10.0%) were the common types of drug eruptions. The common causative agents were antibiotics/antimicrobials, antipyretics(NSAIDs, and CNS depressants. 52 patients out of 103 had positive results after at least one skin test with suspected drugs. CONCLUSION: In our study, we were ahle to obtain somewhat meaningful results basnl on data from the combination of various skin tests. As a result, physicians need to prescrible drugs with care.

Primary Cutaneous Cryptococcosis Treated with Itraconazole / 대한의진균학회지

In most instances, Cryptococcosis is a systemic disease caused by the yeast-like fungus Cryptococcus neoformans through respiratory tract. The organism is worldwide in its distribution, is saprophytic, and is found in soil and in pigeon excretion. Primary cutaneous cryptococcosis is rare; skin lesion is the sole manifestation of the disease without preceding generalized or cerebrospinal involvement. We report a case of primary cutaneous crytococcosis. The patient was a 53-year-old female, who had had an erythematous ulcerated lesion with swollen border on the dorsum of right wrist. Histopathologic examination showed typical spores with capsules. Other physical examinations and laboratory findings were within normal limit. The lesion was successfully treated with oral itraconazole (200mg/dayx7weeks).
