BACKGROUND: The differentiation between basal cell carcinoma(BCC) and trichoepithelioma(TE) is sometimes difficult clinically and histologically, and their differentiation is important since their treatment and prognosis are sometimes different. OBJECTIVE: Our purpose was to investigate whether there was a difference in CD34 staining patterns in the stromas (immediate and distant stromas from the tumor lobules) of BCC and TE, since the histopathologic characteristics of the stromas are one of the most important features to differentiate the two tumor. METHOD: We perfomed immunoperoxidase staining(modified ABC technique) by using a monoclonal anti CD34 antibody(QBEND10, IgG1) on the formalin-fixed, paraffin-embedded biopsy specimens of 11 BCC as and 10 TEs. RESULTS: 1. In the immediate strcimas, spindle-shaped cells were stained in 4 out of ll cases of BCC and in 9 out of 10 cases of TE. However, the staining patterns observed in the 4 cases of BCC were all loosely scattered, week staining, while those of the 9 cases of TE were all densely compact, strong staining. CD34 was not expressed in one case of TE. 2. In the distant stromas, all cases of BCC and TE showed staining of loosely scattered spindle-shaped cells, and there was no difference in staining patterns of the two tumors. 3. Papillary mesenchymed bodies were observed in 8 cases of TE and in none of BCC, and they expressed CD34 focally. CONCLUSION: CD34 sta ining patterns of the immediate peritumoral stromas of BCCs and TEs were different and could differentiate the two tumors.

BACKGROUND: Psoriasis is a disabling and intractable disease influencing the psychosocial life of the patients. Patients who are frustrated with orthodox medicine may explore alternative therapies. OBJECTIVE: This study was done to research on the actual condition of the use of alternative medicine in the patients with psoriasis. METHODS: A self-administered questionnaire was constructed, and was given to the patients to answer our questions. RESULTS: Among 128 patients with psoriasis, 61 (47.7%) reported previous use of one or more forms of alternative medicine. The absence of satisfactory long-term effects of physician-provided therapy was the main reason for patients trying alternative medicine. Persons without skin s disease and the mass media were the main sources of information on alternative medicine. CONCLUSION: Alternative therapies were widely utilized by subjects participating in this study, and dermatologists need to be aware of alternative treatments employed by their patients.

Kimura's disease is a chronic inflammatory condition of unknown cause. It usually appears as a painless nodule in the head and neck region often associated with regional lymphadenopathy, but there have rarely been reports of penile involvement or clinical presentation as an ulcerative plaque. We present a case of Kimura's disease occurring on the penile shaft as an ulcerative plaque in a 44-year-old man. A vesicular eruption had occurred on his penile shaft followed by an ulcerative plaque for 2 months. He had suffered from recurrent regional lymphadenopathy for 15 years and he had also exhibited intermittent eosinophilia. Histopathologic findings revealed diffuse eosinophilic infiltration in the dermis of the skin and eosmophilic abscesses in the lymphoid follicles of the mguinal lymph node. After short-term systemic steroid therapy and local injection of triamcinolone acetonide, the ulcerative plaque was healed.

We herein present a rare case of a 42-year-old man with primary cutaneous marginal zone lymphoma(MZL) of the B-cell type on his shin. MZL is known to be the cutaneous counterpart of MALT(mucosa-associated lymphatic tissue) lymphoma. Histopathologically, MZL is characterized by multi-nodular infiltrates of centrocyte-like and centroblast-like marginal cells with bottom-heavy patterns, lymphoplasmacytoid differentiation, typical distribution of tumor cells in the marginal zone and follicular colonization by tumor cells. This B-cell lymphoma of a benign grade should be differentiated from mantle cell lymphoma and follicular center cell lymphoma.

Pearly penile papules are small, smooth, dome-shaped, grayish to skin-colored papules, that are arranged in one or several rows. These are commonly located circumferentially on the corona and sulcus of the glans penis. A 36-year-old male patient had had asymptomatic numerous pearly smooth 1 * 1mm -sized dome-shaped papules for several months. A Histopathological examination revealed an increased number of fibroblasts on the papillary dermis, vascular proliferation and a mild lymphocytic infiltration. We diagnosed the condition as pearly penile papules. No treatment other than reassurance was given. We report, herein, a case of pearly penile papules.

The purpose of this study was pertinent design of the framework of the fixed bone anchored bridge using implants in the edentulous mandible through analysis of stress distribution by the three dimensional finite element analysis method. The results were as follows: 1. The L-shaped framework was favorable in restoring the edentulous mandible by implants and fixed bone anchored bridge. 2. The structure of the framework should be designed to endure the occlusal load because of stress concentration at the most distal abutment of the framework. 3. The stress at the distal implant where cantilever starts was twice as much as that of other portions. 4. Compressive stress was generated on the framework of the mesial side of the distal implant and extrusive force was induced to the mesially positioned implants. 5. The height of vertical plate was high as possible as can be to distribute stresses concentrating bucco-lingually and labio-lingually in the framework between abutments, 6. Reinforcement of the horizontal plate thickness was needed because stress was loaded more on the horizontal plate than on the vertical plate of the framework. 7. Lengthening of the vertical plate can compensate for any limitations in horizontal plate width.
