Abstract PDF: To evaluate whether mast cells are involved in developing pathologic feature of psoriasis, 60 biopsy specimens of patients with psoriasis were analyzed. They had not been treated for at least 1 week before skin biopsy. Histological findings in early and fully developed lesions and numbers of mast cells in their dermal papillae were investigated. The results were as follows: 1. In epidermal changes of psoriatic lesions, parakeratosis and acanthosis revealed different findings between early lesions and fully developed lesions. While early lesions revealed mounds of parakeratosis and mild to moderate acanthosis, fully developed lesions revealed confluent parakeratosis and moderate to severe acanthosis. In dermal changes of psoriatic lesions, papillomatosis revealed different findings between early developed lesions and fully developed lesions. While early lesions revealed normal to moderate papillomatosis, fully developed lesions revealed moderate to severe papillomatosis. 2. Degree of acanthosis is related to the degree of papillomatosis. The more increase in the degree of acanthosis, papillomatosis, and parakeratosis, mast cell numbers in dermal papillae were more increased. 3. Mast cell numbers in dermal papillae were more increased in fully developed lesions than early lesions. 4. These findings suggest that mast cell may play an active role in developing pathologic finding of psoriasis.

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

Abstract PDF: We report a case of metastatic carcinoma of the skin in 62-year-old male who showed multiple nodules on the anterior chest, scalp, face and left axilla for 2 months duration. He suffered from lower abdominal discomfortness for 6 months. Histopathologic findings revealed atypical cell nests and some tubular or glandular formation in the dermis and subcutaneous fat tissue. Material in the lumen showed diastase resistant and PAS positive, and alcian blue positive at pH 2.4, but negative pH 0.4. So it represented sialomucin. We did not find primary site of malignant tumor. In view of clinical and histopathological findings, it was considered to be originated from the large intestine.
