We experienced a case of childhood derrnatomyositis associated with calcinosis universalis in a 3-year-old boy. The skin lesion showed generalized, hard nodules and ulcers, 0, 3-1 cm in cliameter, or the trunk and buttock.

A 24-year-old female who have had pseudoxanthoma elasticum for 14 years, showed brownish, umbilicated papules forming serpiginous pattern on the anterior neck, A skin biopsy specimen from the neck lesion revealed epidermal hyperplasia and perforating canal containing basophilic, necrotic materials and degenerated elastic fibers, also showed short, swollen and irregularly clumped elastic fibers in the lower dermis.

Dermographism: I . The Prevalence in Korean general Population / 대한피부과학회지

The prevalence of dermographism in the general population of Korea was studied using a dermographic tester on 1, 074 persons(M: 489, F: 585, M/F= 1/l. 2). The result was summarized as follows: 1. The prevalence of dermographism from the pressure of 4, 800 Gm/sq. cm (pressure 2) was 6. 7%. 2. There were no significant difference in the prevalence between male(6.3%) and female(7%) (p>0. 1). 3, The peak age group of dermographism was third(9.4%), fourth and second decades in decreasing order.

Histopathological Observation of Fixed Drug Eruption / 대한피부과학회지

Thirty-nine patients with fixed drug eruption who visited the Department of Dermatology in National Medical Center from January 1g7g to December 1982 were selected. Among them, twentyseven patients performed skin biopsy and were evaluated histopathologically on the basis of duration. The results were as follows; ].In the early stage less than 1 week of duration, hydropic degeneration of basal cells, necrotic keratinocytes with eosinophilic cytoplasm and pknotic nucleus in the epidermis, and mixed cell infiltration with eosinophlis in the upper dermis were prominently. In the late stage more than 20 days of duration, acanthosis, an increased amount of melanin in the basal cell layer and presence of melanophages were found more prominent, however, hydropic degeneration of basal cells, papillary dermal ederna, inflammatory infiltration of mononuclear cells were found less prounced or absent.
