Bronchogenic cysts can arise either in the mediastinum or in the lung parenchyma. On both CT and T1 -weighted MR images, the cyst contents can show a variable signal characteristics. However, on T2-weighted MR images, the cyst show high signal intensity. Although unusual, the cyst may communicate with the tracheobronchial tree and demonstrate partial or complete air content. With hemorrhage, fluid-fluid levels can also be seen within the cyst. Pathologically, the diagnosis of bronchogenic cyst rests on demonstration of tissues normally found in the tracheobronchial tree within the cyst wall.

Reconstruction of the anophthalmic contracted socket was performed in 28 eyes (34 cases) from October 1981 to February 1985. The follow-up period after surgery ranged from 6 months to 12 months. The age range of the patients was from 5 years to 60 years, and there were 25 males and 3 females. Degree of the contraction and method of the operation were as follows: 1. Mildly contracted socket. Among 12 eyes, 7 eyes were operated with acrylic conformer(AC) after buccal mucous membrane graft(BMMG) and 5 eyes with dental conformer(DC) after buccal mucous membrane graft. 2. Moderately contracted socket. Among 9 eyes, 6 eyes were operated with AC after BMMG and 3 eyes with DC after BMMG. 3. Severely contracted socket. Among 7 eyes, 5 eyes were operated with AC after BMMG and 2 eyes with DC after BMMG. The results were as follows: 1. Etiology of the contracted socket was inflammation(12 eyes: 43%), trauma(7 eyes: 25%), burn(5 eyes: 18%) and irradiation(4 eyes: 14%). 2. In reconstruction of the contracted socket, buccal mucosa was a good substitute for conjunctiva. 3. Better result was obtained in the cases with lesser contraction preoperatively, and in the cases of reconstruction after preoperative repair of lid defect. 4. The optimal interval for further surgery was at least about 6 months due to resolution of the fibroblastic activity. 5. Postoperative complications were noted in 8 cases(24%), which were recontraction in 4 cases(12%), shrinkage of the graft in 2 cases(6%), necrosis of the graft in 1 case(3%), and infection in 1 case(3%). 6. Most patients now wear artificial eyes with or without lightly tinted glasses, giving them good appearance, even though their sight was gone.

To understand the role of Transglutaminase K(TGase K) in skin diseases, the expression of TGase K protein was studied in hyperkeratotic inflammatory skin diseases, and in several different kinds of benign and malignant skin tumors. Immunohistochemistry was used to detect the TGase K protein with a new anti-human TGase K polyclonal antibody. This antibody showed the same immuno- histochemical staining pattern as in previously published immunofluorescence data with the exception that the immunohistochemical stain showed a slightly weaker stain in the granular layer. However, the staining intensity was decreased in psoriasis, which is opposite for results obtained with the widely used TGase K monoclonal antibody B.C1. In other hyperkeratotic inflammatory skin diseases, like pityriasis rubra pilaria, lichen planus, and pityriasis rosea, the staining patterns were similar while the staining intensity was decreased, compared to normal epidermis. Squamous cell carcinoma showed a diffuse staining pattern in tumor cells with a small intensity increase in well differentiated tumor cells. However, in actinic keratosis and Bowen's disease, which are thought to be precursors of squamous cell carcinoma, the staining intensity was weak. The tumor cells of basal cell carcinoma, malignant melanoma, and seborrheic keratosis showed a weak staining intensity.

House dust mites, Dermatophagoides farinae and Dermatophagoides pteronyssius have been identified as the main sources of house dust allergen and are considersed the most important causative allergen in the ethology of allergic respiaratory disease and allergic rhinitis. To evaluate the incidence of positive skin reactivity to house dust mites and relationship between total serum IgE levels and specific IgE antibody to house dust mites, we performed allergic skin test (scratch) in 182 children with allergic respiatory disease and atopic dermatitis. We also checked serum total IgE by PRIST method and specific IgE antibody to D. farinae and D. pteronyssinus by ELISA. Our results showed that positive skin reaction was observed in 79% of patients in D. farinae, 71% in D. pternyssinus. There was a significant correlation between serum total IgE and IgE antibody specific to D. farinae (r=0.55, p<0.001). Serum total IgE and specific IgE antibody to D. petronyssinus had no significant correlation (r=0.39, p<0.001). D. farinae and D. pteronyssinus had close correlation in the skin test (r=0.82, p<0.0001) and relative concentration of specific IgE antibody (r=0.73, p<0.0001). The agreement between skin reaction and relative concentration of specific IgE to House dust mites was 68% in D. farinae and 63% in D.pteronyssinus.

Linear IgA bullous dermatoses(LABD) occurring in childhood is considered to be a childhood counterpart of LABD,rather than chronic bullous dermatosis of childhood. This disease characteristically involves the perioral area,lower trunk,pelvic region and the lower extremities. Immunopathologically,it is characterized by the linear deposits of IgA at the dermoepidermal junction of the perilesional skin. A 20-month-old female infant presented with multiple pruritic tense bullae on the face, lower trunk, both extremities and pelvic region of 2 weeks duration. She had no oral lesions or any specific signs or symptoms referable to the disease of the gastrointestinal tract. A skin biopsy revealed subepidermal blisters infiltrated with many neutrophils and a few eosinophils. Direct immunofluorescence demonstrated linear deposition of IgA at the dermoepidermal junction. An indirect immunofluorescence study using NaC1-split skin as the substrate revealed fluorescence for IgA in a linear pattern on the roof of the split at a titer of 1:40. The clinical diagnosis of LABD of childhood was confirmed and we started with a combined remedy of dapsone and corticosteroids; 10 weeks later almost all of the lesions had disappeared.

BACKGROUND: Calcium gluconate intralesional injection which is widely used as topical treatment of hydrofluoric acid burn gives doctors some inconvenience, since it requires a certain care about the quantity and pressure of infiltration and so on. Therefore we made calcium gluconate jelly, as the suggestion of Kono, for the convenience of topical use. OBJECTIVE: The purpose of this study was to evaluate the therapeutic effect of calcium gluconate jelly in hydrofluoric acid burn. METHODS: After carefully shaving off the hair of the back of guinea pigs, each side of the back were burned by three concentrations(5%, 25%, 50% ) of hydrofluoric acid. Left side of guinea pigs back(control group) was treated with saline and hyamine lavage, right side(treated group) was applied with calcium gluconate jelly after hyamine lavage. Then we evaluate the clinical and histologic feature accorriing to each time. RESULTS: Clinical findings : In 5% hydrofluoric acid burn, both group showed no clinical response until 5 days. In 25% hydrofluoric acid burn, a mild erythema began from 3 hours after exposure in control group, but it began from 12 hours in treated group. In 50% hydrofluoric acid burn, moderate degree skin ulcer developed after 2 days in control group, but it developed after 3 days in treated group. Histopathological findings: In 5% hydrofluoric acid burn, only some inflammatory cell infiltrates in upper dermis were observed in both group after 5 days. In 25% hydrofluoric acid burn, both group showed epidermal cell damage after 6 hours. After 5 days subepidermal bullae and inflammatory cell infiltrates in upper dermis were observed in control group, but only shallow subcorneal bullae and inflammatory cell infiltrates were observed in experimental group. In 50% hydrofluoric acid burn, control group showed epidermal cell damage after 3 hours and subcutaneous fat necrosis were observed after 5 days. But in experimental group epidermal cell damage began after 6 hours, and only subepidermal bullae and inflammatory cell infiltrates in mid dermis were observed after 5 days. Subcutaneous fat necrosis was not observed until 5 days in experimental group. CONCLUSION: Calcium gluconale jelly and hyamine solution showed the same therapeutic effect in low concentration(5%) hydrofluoric acid burn. But, in mid to high concentration(25%, 50%) hydrofluoric acid burn, topically applied calcium gluconate jelly significantly reduce the tissue damage comparing with hyamie solution. It suggest the therapeutic effect of calcium gluconate jelly in hydrofluoric acid burn treatment is more convenient form.

Clear cell meningioma is a recently recognized morphologically unique entity. It shows no sex predilection, affects primarily the lumbar region, and the cerebellopontine angle. Despite its benign appearance, it may be aggressive, particularly in intracranial cases. All lesions are moderately cellular, with the exception of stromal hyalinization. The tumor consists largely of a sheet- like or somewhat lobular pattern of polygonal cells, the cytoplasm of which is clear. No close association is noted between the recurrence or the clinical outcome and factors such as mitotic activity, the PCNA index, and the DNA ploidy status. But the MIB-1 proliferation index is appreciably higher in recurrent tumors. We experienced a case of clear-cell meningioma showing a characteristic histologic finding. A 39-year-old man was admitted due to the recent onset of right-sided, facial-nerve palsy, left hemiparesis and general weakness. A CT scan of the head showed a well defined mass in the petroclival area. After surgical resection, the patient was in good condition, but 1 year later symptoms recurred. A CT scan of the head showed a huge, recurrent petroclival tumor with adhesion to the surrounding brain parenchyme.

Pigmented photoallergic contact dermatitis is a disease usually resulting from recurrent cutaneous exposure to cosmetic photoallergens which produce bizarre dark brown hyperpigmentation. Histologicnl examination of this condition reveals liquefaction of the basal cells of the epidmis and melanophages in the upper dermis. A 50-year-female developed dark brownish mottled hyperpigmented patches on her face after using a soap named O.E. and taking a nap every afternoon for 4 years. The histological fmding on the lesion site was consistent with pigmented photoallergic contact dermatitis. The cosmetic photopatch test with, O.E. soap, and the Scandinavian scries resulted in a positive reaction only on one side where 5 J/cm2 lights were applied by using Waldman 800UV machine. The other side howed a negative finding. We fmally diagnosed pigmented photoallergic contact dermatitis based on the patients histoty of using the soap containing musk ambrette, a histological examination of a biopsy and the results of photopatch tests. We report rare case of pigmented photoallergic contact dermatitis.
