BACKGROUND: The immortalized human keratinocyte line, HaCaT cells have been widely used as substitutes for normal epidermal keratinocytes. Recently, reconstruction of a skin equivalent using HaCaT cells showed a multilayered epithelium,but somewhat different tissue architecture as compared with normal epidermis. OBJECTIVE: In this study, using HaCaT cells we tried to reconstruct an epidermis resembling more closely to normal epidermis than the previous results. MATERIALS AND METHODS: HaCaT cells were cultured in air-liquid interface on a recently developed dermal substrated in our laboratory, de-epidermized dermis (DED) raised on fibroblast-populated collagen matrix and the result was compared with those on DED or fibroblast-populated collagen matrix alone. RESULTS: HaCaT cells on the new dermal substrate formed a multilayered epithelium with rete ridges, showing rather orderly cellular organization compared with those on fibroblast-populated collagen matrix. However, horny and granular layers were not observed contrary to normal epidermis. Immunohistochemical studies revealed that differentiation markers such as keratin 1, keratin 6 and involucrin showed the similar pattern to those in HaCaT cells cultured on fibroblast-populated collagen matrix. Markers of terminal differentiation, loricrin and filaggrin were not expressed contrary to normal epidermis. CONCLUSION: These results suggest that organotypic culture HaCaT cells on the dermal substrate combines DED with fivroblast-populated collagen matrix results in incomplete differentiation of HaCaT cells contrary to normal keratinocytes.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.

Hydrogen peroxide is a commonly used oxidizing agent. If injected, it may result in morbidity via direct caustic injury, oxygen gas formation, and lipid peroxidation. We report a 40-year-old male patient who accidentally swallowed undiluted hydrogen peroxide (35%). The initial chest computed tomography scan showed no active lesions. He was admitted to the intensive care unit for conservative treatment. Fourteen days after treatment, uncontrolled fever and foul oder sputum occurred, which was not alleviated despite empirical antibiotics therapy. Findings on a chest computed tomography showed tracheo-esophageal fistula at the lower trachea and left main bronchus. He underwent surgical replacement surgery and was discharged without complication after 52 days of admission.

PURPOSE: In patient with blunt trauma of chest, supine AP x-ray cannot differenciate the lung contusion, laceration, atelectasis, and hemothorax definitely. Therefore, computed tomographic evaluation is needed for accurate evaluation of the injuries. In our knowledge, there are few reports about CT findings of blunt chest trauma, in our country, therefore we tried to fiud the characteristic CT findings in patients with blunt trauma. MATERIALS AND METHODS: We analyzed the plain x-ray and CT image of 4 patient with blunt chest trauma. Location and morphology of lung parenchymal contusion and laceration, hemopneumothorax, chest wall injuries and location of chest tube. RESULTS: Lung parenchymal contusion was noted in 53 segments. of 16 patiants'infiltration(n=27 segment), and multiple nodular pattern was noted in 15 segment, pattern of consolidation along the lung periphery was seen in 11 segment. Laceration was noted in 18 lesion and most commonly located in paravertebral area(b=8). CONCLUSION: CT scan of chest in patient with blunt chest trauma, provides accurate informations of the pattern of injuries, and localization, therefore, should be performed as po9ssible.

We herein present a case of bullous lichen planus in a 56-year-old female. She had had a generalized eruption of lichen planus with violaceus papules and plaques. many of which had been surmounted by vesicles and bullae. The histopathologic findings of a bulla revealed hyperkeratosis, irregular acanthosis, subepidermal bulla and upper dermal band-like cell infiltration. The patient had been treated with dapsone but the lesions had not been significantly improved.
