This study was carried out to evaluate the expressions of the p53 protein, the estrogen receptor (ER) and the progesterone receptor (PR), as well as the relationship between their expressions and clinicopathologic prognostic factors with storage duration of a paraffin block, and correlation between the p53 protein, the ER and the PR expressions in 29 cases of leiomyosarcoma of soft tissue. The expressions of the p53 protein, the ER and the PR were semiquantiatively analyzed in paraffin sections by the immunohistochemical method out of 29 cases the p53 protein, ER and PR were expressed in 9 (31.0%), 2 (6.9%) and 5 (17.2%), respectively. The expression of the p53 protein was not significantly associated with sex, age, anatomic site, tumor size, tumor depth, histological differentiation or mitotic rate (p>0.05), but statistically correlated to storage duration of a paraffin block (p=0.028). There was no significant relationship between the expression of the ER and all the clinocopathological prognostic factors with storage duration of a paraffin block (p>0.05). The expression of the PR was related to the histological differentiation (p=0.02), but not related to other clinicopathological prognostic parameters and storage duration of a paraffin block (p>0.05). The expression of the p53 protein and the PR had a significant relationship (p=0.022), but the expression of the p53 protein and the ER had no significant correlation. In conclusion, these results suggest that the expression of the p53 protein and the PR may play a role in development and growth of soft tissue leiomyosarcoma. Further studies of large numbers are needed to clarify the exact relationship between tumorigenesis and the p53 and the PR expressions in leiomyosarcoma of soft tissue.

We report a case who has been diagnosed as lipodytrophia centrifugalis abdomialis juvenilis. The patient was a 9 year-old girl. At the age of 4 years, these well-defined, depressed lesions appeared in both ing-uinal areas and gradually spread to the labia major, the abdomen and both flank areas and, by 9 years, had reached lower portion of the chest. Biopsy specimen from the depressed lesion showed absence of the subcutsneous fat. The epidermal appendage were well preserved. There were lympho-histiocytic infiltrations around the blood vessels in the upper dermis.

This study was carried out to evaluate the immunohistochemical expressions of p53, E-cadherin, and nm23 proteins in 114 cases of metastatic carcinoma of the neck lymph node (MTLNCA) and corresponding primary carcinoma (PRCA). The positive expressions of p53, E-cadherin, and nm23 proteins were 62.3%, 58.8% and 64.0%, respectively in PRCA, and 40.4%, 38.6%, and 43.9%, respectively in MTLNCA with significant down-regulation from PRCA to MTLNCA (p<0.05). The down-regulation was correlated with female gender, moderate and poor differentiation, and adenocarcinoma in p53 protein, female gender, respiratory and gastrointestinal carcinoma in E-cadherin protein, and female gender, respiratory carcinoma, moderate differentiation, and squamous cell carcinoma in nm23 protein (p<0.05). There was no significant relationship among expressions of p53, E-cadherin, and nm23 proteins (p<0.05). In conclusion, these results suggest that the expressions of p53, E-cadherin, and nm23 proteins seem to be down-regulated from PRCA to MTLNCA and this down-regulation may play a role in invasion and metastasis.

The concentrations of fibronectin in aqueous humor, measured by ELISA which was developed to detect fibronectin, ranged from 5 ng/ml to 100 ng/ml. Aqueous humor was aspirated from human eyes with cataracts and glaucomas using a 26 gauge needle through the peripheral cornea before making the limbal incision into the anterior chamber during surgery. The results of the study show that the average concentration and standard deviation of fibronectin was 0.136 +/- 0.192 microgram/ml in cataract eyes, and 0.962 +/- 0.918 microgram/ml in glaucoma eyes respectively. There was a statistically significant difference between both groups (p = 0.000). However, no significant differences according to age and sex were noted. There was no influence due to preoperative intravenous mannitol injection on fibronectin concentration. The source of aqueous fibronectin is still not clearly known and the mechanism of the higher concentration of fibronectin in glaucoma has not been clearly disclosed, however it is thought that normally present fibronectin is accumulated in the anterior chamber because it can not pass the aqueous outflow pathway, or that fibronectin production may be increased in glaucoma.

The increase of serum IgE in atopic dermatitis is well known. And atopic patients are frequently complicated by viral infection, such as molluscum contagiosum. So, we studied the serum IgE level in patients of atopic dermatitis and atopic dermatitis with molluscum eontagiosum to evaluate the relationship between molluscum contagiosum and IgE level in patients with atopic dermatitis. The results were summarized as follows : 1. Serum IgE level in patients of atopic dermatitis was 168.8+117.0 IU/ml, which was higher than that of control group (87.6+/-40.0 IU/ml) (p<0.05). 2. Serum IgE level in patients of atopic dermatitis with molluscum contagiosum was 137.8+/-91.9 IU/ml, which was lower than that of atopic dermatitis without molluscum contagiosum (178.3+/-123.7 IU/ml) (p>0.05).

Photodynamic therapy(PDT) is a treatment modality by highly reactive oxygen intermediates generated through the interaction of light with a photosensiziter. It has been shown to be an effective treatment for various cutaneous and noncutaneous malignancies. It is efficient for the curative and palliative treatment of epithelial skin tumor in situ or early invasive lesions. In effect, it is a useful alternative treatment for the lesions located on anatomically difficult areas or the large-sized lesions. We treated a case of Bowen's disease arising on the plantar area and 3rd and 4th toewebs of left forefoot in a 61-year-old man with PDT using the hematoporphyrin derivative, porfirmer sodium(Photofrin, Russia) as a photosensitizer and gold vapor laser as a visible light source. The outcome showed partial clinical improvement after about 2 months' follow-up.

We present a case of transient acantholytic dermatosis which developed on the face of a 19-year-old Korean girl. Asyrnptomatic pinhead to miliary-grain sized brownish papules arranged in a somewhat band-like outbreak along the left side of the nose for about 3 months. Histopathologic findings were similar to Dariers disease. Immunoperoxidase staining showed that IgG was deposited on the intercellular area of keratinocytes around the suprabasal clefts. Skin lesions disappeared spontaneously in 5 weeks after a skin biopsy.
