Résumé
Lichen amyloidosis is a chronic, benign and relatively rare disease, but not infrequent in Korea. The patients with lichen amyloidosis visited to Dermatologic Department of Severance Hospital in 1969. The results of clinico-pathological findings observed in above patients were presented. Case 1-A 56 year old farmer has been suffered from pruritic lichenoid papules which developed in the right pretibial area for 10 years. These papules were reddish-brown in color, 1 to 2mm in. diameter and closely aggregated. The whole gross lesion measured 10 by 25 cm. Cases 2-A 32 year old obese house-wife complained of pruritic eruptions in the right pretibial area for 3 years. Shiny firm papules, measuring approximately 2 mm in diameter, were red in color and gross entire lesion was estimated to 7 by 10 cm. Histological examination by employing the stain method of crystal violet and the Nomland test demonstrated the amyloid mass in the papillary portion of dermis. All laboratory studies including complete blood count (CBC), chest X-ray, sedimentation rate, urinalysis (including test for Bence Jones protein), blood glucose, blood urea nitrogen (BUN), serum cholesterol, venereal disease research laboratories test for syphilis (VDRL), stool for occult blood, serum protein electrophoresis, electrocardiogram (ECG) and intravenous congo red test, were within normal limit. The therapeutic results were not promissing, however itching and lichenoid papules were disappeared during the treatment with steroid cream for occlussive dressing therapy.
