Classic pulmonary blastoma is a variant of carcinosarcoma which is seen almost exclusively in adults. By contrast, most cases of pulmonary blastoma in children have been described as having an exclusive mesenchymal composition, which was proposed as pleuropulmonary blastoma. Recently we experienced a case of pleuropulmonary blastoma, type 1. This 27-month-old male baby was transferred to our hospital due to the left tension pneumothorax. Chest CT revealed a subpleural pulmonary cystic lesion on the left upper lung and an open cystectomy was performed. Histologically the lesion was composed of variable-sized cystic structures lined with a single layer of respiratory-type epithelium. the underlying stroma was composed of sheets of small, round to oval, primitive tumor cells. Some of them had eccentric, eosinophilic cytoplasm, suggestive of rhabdomyoblastic differentiation. These rhabdomyoblastic cells were fuchsinophilic and positive with desmin and vimentin on immunohistochemistry.

Observations of 50 sporotrichosis patients, who were confirmed by dinical, histopathological and mycological examination, were made in the department of Dermatology at Chon-nam University Hospital for the twelve year period from 1967 to 1978. The results obtained were as follows; 1. During this period, out of a total of 39, 594 outpatients, there were 50 cases of sporotrichosis for an average of 0. 13 percent. The highest incidence was in 1970 with 7 cases, however, there was no period with a particularly marked increase in the occurrence of the disease. 2. Half of all the cases occurred in the third and fourth decades of life. The male to female ratio was 2. 3:1. 3. Occupationally, the greatest percent were farmers, 36 cases(72%), and the next highest, unemployed. 4. In Kwang-ju an.d surrounding 6 counties, there were 25 cases which were widely scattered thraughout Chonnam province and the southern tip of Chonbuk province. 5. The initial lesion appeared on the upper extremities in 39 cases, particularly the right hand, and the lower extremities in 9 cases. 6. Of the total patients, there were 24 cases(48%) with a history of trauma before the onset of the disease. Of those cases, the disease appeared between I and 2 weeks. after trauma in 10 cases(41.7%) and between 2 and 3 weeks in 8 cases(33.3%). 7. The duration of the skin lesions before initial examination was 2 months in 12 cases(24%) and 3 months in 14 cases(28%). 8. Forty six percent of the total cases visited our department in spring, showing a higher incidence than any other season. The highest monthly incidence was in May, when there were 13 cases. 9, Of the total, 42 cases(84%) were cutaneous lymphatic type, while 8 cases(16%), localized cutaneous type.

Severe injuries of hands frequently expose the bone and joint due to the defect of crushing of soft tissues. Although the several methods are introduced, the treatment of bone and joint exposure of finger and hand is very difficult to control satisfactorily. From October 1986 to February 1988, we performed the pedicled skin flap in 11 cases; 9 abdominal skin flaps and 2 pectoral skin flaps. Follow up stuides showed good results. The successful surviving of flaps was accomplished in all cases and the dead bones were regenerated by the creeping substitution. Therefore this pedicled skin flap operation can be considered to be a simple and effective method in treating the bone and joint exposure of fingers.

Radiographic examination of the breast has been so improved that it became a routine complement to physicalexamination. From November 1, 1983 through Sept.30, 1984, 684 patient with complaints of various breast problemwere examined by low-dose film mammography at Yong Done Hospital, Yonesei University. Among them, a comparativestudies, independently conducted physical examination, 97 cases of film mammography, 35 cases of ultrasoundmammography, 16 cases of aspiration cytology, and 3 cases of galactography were performed for our pathologicallyproven 98 cases of breast disease. Combined and complementary studies for breast diseases were analyzed in 37proven cases and authors found that specificity of those combined immediate complementary study techniques forbreast disease were 94% under colose cooperation with surgeon in Yong Dong Hospital, Yonsei University.

Verrucous carcinoma of the larynx is a distinct and uncommon variant of well-differentiated squamous cell-carcinoma. The authors hybridized in situ a case of laryngeal verrucous carcinoma with DNA prebes to humman papillomavirus (HPV) 6, 11, 16, 18, 31, 33 and 35. The DNAs from the verrucous carcinoma of larynx hybridized with mixed DNA probes HPV-16/18 and 31/33/35. In addition, there was an evidence of HPV infection based on hybridization with mixed DNA probe HPV-6/11 in the adjacent papilloma tissue. By in situ DNA hybridization techniques, we clearly demonstrated human papillomavirus (HPV-16/18, and 31/33/35) related sequences in this neoplasm. These findings suggest the role of HPV-6/11 in the development of laryngeal papilloma ad HPV-16/18 and 31/33/35 probably on the progression to verrucous carcinoma.

To determine the optimum concentration of mitomycin C(MMC) in patients with refractory glaucoma undergoing trabeculectomy, we retrospectively examined 31 eyes of 22 patients with refractory glaucoma who underwent trabeculectomy with 0.25mg/ml MMC for 5 minutes. They were case matched with a group of 36 eyes of 28 patients who had undergone trabeculectomy with 0.5mg/ml MMC for 5 minutes by using age, gender, type of refractory glaucoma, preoperative intraocular pressure(IOP), and preoperative medications as variables. MMC was applied between the sclera and Tenon's capsule during trabeculectomy, and scleral flap was closed with tight releasable sutures. No statistically significant differences were found in mean IOP between the two groups at the one, three, six, and nine months postoperative periods. The mean follow-up was 9.3 months in the 0.25mg group and 9.8 months in the 0.5 mg group(p=0.70). At the last postoperative visit, 81%(25 eyes) in the 0.25mg group and 86%(31 eyes) in the 0.5mg group had an IOP less than 21mmHg with or without glaucoma medication(p=0.79). At the last postoperative visit, there were no statistically significant differences in mean IOP(17.2 +/- 8.6mmHg and 17.2 +/- 7.3mmHg, respectively, p=0.99), mean number of medications(0.6 +/- 0.9 and 0.5 +/- 0.7, respectively, p=0.77), and change in visual acuity(3 eyes and 6 eyes lost more than 2 lines of vision, respectively, p=0.75) between the two groups. The incidence of complications were similar between the two groups. Our data suggests similar efficacy and safety in trabeculectomy with 0.25 and 0.5mg/ml MMC for 5 minutes.
