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.

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.

Achondrogenesis type 2 is a lethal form of congenital skeletal dysplasia characterized by severe short-limbed dwarfism, decreased vertebral ossification and normal ossification of the skull. We report an autopsy case of achondrogenesis type 2 in a female fetus terminated at 29 weeks of gestation. External morphology revealed a relatively large head, short upper and lower extremities, short neck, and distended abdomen. The x-ray finding showed normal calvarial ossification, hypoplastic ilium and unossified ischium, and metaphyseal flares of the femur and tibia. Histologically, chondrocytes were large and irregular with increased vascularity.

Gastrointestinal angiodysplasia is a distinct disease entity which causes frequent gastrointestinal bleeding. It predominantly arises at the stomach and duodenum in the upper gastrointestinal tract and cecum and ascending colon in the lower gastrointestinal tract. The general histological finding of the angiodysplasia is a submucosal vascular ectasia and tortuosity. We have experienced two cases of the intestinal angiodysplasia. The first case occurred on a jejunum in a 22-year-old woman who had anemia. The second case occurred on a sigmoid colon in a 59-year-old man who had constipation. In addition to the general histologic finding of the angiodysplasia, the microscopic findings of the first case revealed some capillary hemangioma-like areas; and in the second case, there was a marked ischemic change and the thickening of the wall.
