The frozen section technique is a means of intraoperative pathological diagnosis, and a procedure of great value to the surgeon. This method should be accurate, rapid and reliable. This method serves useful purposes, such as determining the presence of tumor, its type (especially whether it is benign or malignant), the adequacy of a biopsy of a suspected lesion, and the conditions of the surgical margins. But, it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations, and the accuracy of the frozen section method and the materials studies was total of frozen section diagnosis of 809 cases was 98.1% with 0.5% of false negative, 0% of false positive 0.5% of incorrect histological diagnosis or grading errors, and 0.9% of deferred cases. The tissues submitted were lymph node, gastrointestinal tract, skin subcutaneous tissues in decreasing oder of frequency. The false positive case is not present, while the false negative cases were 4.

For evaluation on the histopathologic studies and age distribution of the testicular tumors in the Taegu area, the inguinal orchidectomized materials were collected at the Department of Pathology, College of Medicine, Yeungnam University, and the analyzed results were as follows: 1. In total of 11 cases of orchidectomized materials, germ cell tumors are 10 cases (90.9%). In germ cell tumors according to the histologic types, seminoma was 5 cases (45.5%), and embryonal carcinoma, 3 (27.2%). 2. The highest age incidence of the group is 20th and 30th, and the next, 50th and 10th.

The allergic skin test and RAST are used commonly to demonstrate the presence of skin sensitizing IgE antibody in the diagnosis of allergic disease. To evaluate the agreement rate and correlation between results of skin test and RAST (radioallergosorbent test) in allergic subject, 83 allergic childhood with positive skin test (bronchial asthma: 26, allergic rhinitis: 27, atopic dermatitis and urticaria: 6 bronchial asthma and allergic rhinitis: 24) and 16 nonallergic childhood were studied. The results were as follows. 1) Peripheral eosinophil counts were significantly elevated in groups with bronchial asthma, allergic rhinitis, bronchial asthma & allergic rhinitis except atopic dermatitis & urticaria group in comparison with normal control group. 2) Serum IgE levels were significantly higher in groups with bronchial asthma, allergic rhinitis, bronchial asthma & allergic rhinitis than in normal control group except atopic dermatitis & urticaria group but there was no significant differences among study groups. 3) RAST units of D.p and D.f were significantly higher in study group except atopic dermatitis & urticaria group. RAST units of cockroach, however, were not significantly increased but in D.f, combined group of bronchial asthma & allergic rhinitis was significantly higher than bronchial asthma or allergic rhinits (p<0.05). 4) Each agreement rate between 3+ skin test and positive rate of RAST in D.p, D.f, cockroach was 37.5%, 63.6% and 12.5% respectively and 4+ skin test and positive rate of RAST was 84.0%, 89.1% and 38.4%. 5) Correlation coefficient between skin test and RAST was 0.71 in D.P, 0.59 in D.f and 0.23 in cockroach. In conclusion, there was difference in agreement rate between positive skin test and RAST to each allergen. Agreement rate between positive skin test and RAST was higher in D.p and D.f. These results suggest that RAST can be used simultaneously with skin test for detecting allergens.

Nemaline myopathy is a rare congenital m opathy, characterized by nonprogressive or slowely progressive muscle weakness associated with rod-like structures in muscle fibers and characteristic dysmorphic features. We report the first farnilial nemaline myopathy in two generations of the same family, confirmed by muscle biospy in an 11-year-old boy and his mother. The patients had hypotonia and slowly progressive muscle weakness of the four limbs associated with characteristic facial dysmorphism and skeletal deformities. Light and electron microscopic study of a muscle biopsy showed numerous nemaline rods in both patients.

Fibrofolliculoma is a benign follicular neoplasm which usually occurs in multiple and rarely solitarily. We have found only seven cases of previous reports of solitary fibrofolliculomas worldwide and only two in Korean literature. Herein we report on a 40-year-old female patient with a solitary flesh-colored bean sized mass on the scalp which histopathologically proved to be a fibrofolliculoma.

For evaluation on the histopathologic studies, and age and sex distribution of the gatric carcinomas in the Taegu Area, the gastrectomized and gastroscopic biopsy materials were collected at the Department of Pathology, College of Medicine, Yeungnam University, and the analyzed results were as follows: 1. In total of 350 cases of gastroscopic biopsy materials adenocarcinomas are 344 cases (98.3%), squamous cell carcinomas and undifferentiated carcinomas are only 6 cases (1.7%). In adenocarcinomas the most of all are tubular type, 215 cases (61.4%). In age distribution the highest is the 50th age group, and 120 cases (34.3%), the next 60th, 81 cases (23.1%), 40th, 76 cases (21.7%), respectively. 2. In total of 130 cases of gastrectomized materials adenocarcinomas are 127 cases (97.7%), and are the highest incidence, the next, carcinomas originated from chronic peptic ulcer of the stomach, and are 3 cases (2.3%). In adenocarcinomas the highest are tubular type, 86 cases (66.2%), the next, signet ring cell type, 20 cases (15.4%). The highest age incidence of the age group is 50th, and the next, 60th, 40th, 30th, 70th and 10th age group, respectively.
