The purpose of this study was to evaluate the in vitro antifungal effect of several kinds of denture lining materials containing nystatin and silver-zeolite on Candida albicans. Three commercially available tissue conditioners (Soft-Liner, Coe-Comfort, Coe-Soft) and two direct denture relining materials (Tokuso Rebase, Durabase) were selected. In terms of the zone of inhibition and some basic physical properties, I could find the following results ; 1. Nystatin or silver-zeolite included in those relining materials had definite antifungal activities against the Candida albicans. 2. As times went on, both of the antifungal agents's activities decreased gradually. 3. Antifungal agents did not affect the relining materials' basic physical properties. 4. Direct chairside relining materials showed unfavorable dark discoloration with response to sil-ver-zeolite.

BACKGROUND: Calcinosis cutis may occur when connective tissue is abnormal (dystrophic), or where calcium or phosphate levels in the blood are high(metastatic); alternatively, there may be no obvious underlying cause(idiopathic). The exact incidence of calcinosis cutis in dermatologic patients is not well-kniown and the pathomechanism of it remains to be elucidated. OBJECTIVE: This study was performed to analyze the incidence, clinical and histopathological features of calcinosis cutis. METHODS: We studied 72 patients with calcinosis cutis who visited our department between January 1985 and December 1996. The patients were classified into 3 types (dystrophic, metastatic, and idiopathic) and were analyzed clinically and histopathologically. Results : The results were summerized as follows; 1. There were 60 cases(83.3%) and 12 cases(16.7%) of the dystrophic and idiopathic types, respectively but the metastatic type was not observed. The frequency of dystrophic calcification in individual disorders was 88.2% in pseudoxanthoma elasticum, 66.7% in trichilemmal cyst and dermatomyositis, and 64.6% in pilomatrichoma. 2. In the idiopathic type, it was common in females aged over 50 years and the mean duration of lesions was 2.8+/-2.0 years. The predilection site was the flank(5 cases) and most of the lesions(7 cases) showed skin-colored nodules 3. Histopathologically, calcified material of the idiopathic type was located predominently in the dermis(10 cases) and was present as large masses surrounded by a foreign body reaction. 4. In the dystrophic type, calcified deposits were noted predominently within the shadow cells of pilomatricoma, in the degenerated elastic fibers of pseudoxanthoma elasticum, and in the keratinized area of basal cell carcinoma, squamous cell carcinoma, trichilemmal cyst, and epidermal cyst. Foreign body reactions with giant cells and mononuclear cell infiltrations were often found around large deposits of calcium. Conclusion : The incidence of calcinosis cutis in dermatologic patients is relatively low, but a variety of disorders can be associated with cutaneous calcification. Therefore, dermatologists should be familiar with the different forms of cutaneous calcification and the dermatoses that manifest them.

Cambison ophthalmic ointment is an easily available topical medicament in Korea, However, the allergic contact dermatitis lo Cambison ophthalmic ointment has not been reported in Korean dermatology literature. We report, a case of allergic contact dermatitis in a 28-year-old female who suffered from itchy, erythematous patches on both periorbital areas. She wore contact lenses and for the last year, she hac applied Cambison ophthalmic ointment to both periorbital areas. The skin lesions were aggravated gradually. A patch test showed positive reactions to Cambison ophthalmic ointment, neomycin, mercury and thimerosal. We suspect neomycin contained in Cambison ophthalmic ointment to be the etiologic agent. When contact dermatitis occurs on periorbital areas, topical ophthalmic ointment or lens cleaner may be considered as a causative agent.

Keratosis punctata of palmar creases has been considered an uncommon variant of keratosis punctata, which itself is considered rare condition. Clinically our case, 32-year-old seaman, shows cup-shaped depression of the epidermis of varying size, from 1-3mrn in diameter, limited to the large flexor creases of the palms and digit. The histologic features are hyperkeratotic and slight acanthotic central epidermal depression without parakeratosis and loss of granular layer. A sparse mononuclear infilterate are seen arround the capillaries in the dermal papillas. No relationship to arsenical agents, syphilis, or genetic factors can be ascertained by history.

A case of sacrococcygeal chordoma diagnosed by fine needle aspiration is presented. This is a case of a 54-year-old woman who came with coccygeal pain of 5-6 months duration. Aspiration biopsy cytology revealed many nests of cells having abundant bubbly cytoplasm and round to oval variably sized nuclei. The cells had indistinct cytoplasmic borders and many of the cells had cytoplasmic vacuoles. The nuclei had thin regular nuclear membranes, finely granular chromatin and one or two small nucleoli. The cells were generally monotonous, but focally pleomorphic with giant cell formation. Mitotic figures were scanty. The backgroud of the aspirate contained abundant mucinous materal. These findings were typical of those of recorded chordoma cases and the diagnosis was confirmed by a following open biopsy. The patient received 4,000 rads of neutron radiotherapy and has been well till March '88.
