The cystic hypersecretory duct carcinoma of the breast was first described in 1984 by Rosen and Scott and warrants separate discussion because of its unusual pathological features. It is morphologically distinguishable from juvenile (secretory) carcinoma and from mucinous (colloid) carcinoma or mucocele-like tumor. We present a case report of intraductal cystic hypersecretory carcinoma of the breast with hormone receptor and oncogene study. The histologic differential diagnosis, with an emphasis on benign lesions that may have a predominant cystic component, is also discussed.

2.A study on the relationship between tooth size and arch dimension in dental crowding.
Korean Journal of Orthodontics 1988;18(1):217-226
This study was undertaken to examine relationship between tooth size and arch dimension in dental crowding. Two groups of dental casts were selected on the basis of dental crowding. One group, consisting of 51 pairs of dental casts (24 male and 27 female), exhibited remarkable dental crowding. A second group, consisting of 60 pairs of dental casts (30 male and 30 female), exhibited little or no crowding. Mean and standard deviation of the following parameters were used to compare two groups: individual and collective mesiodistal tooth diameters, buccal and lingual arch widths and arch area. The following results were obtained. 1. The crowed group revealed larger tooth size than non crowd group. (p<0.01) 2. The crowded group smaller maxillary dental arch dimension than noncrowded group except lingual arch width at canine region. (p<0.01) 3. The crowded group revealed smaller mandibular dental arch dimension than noncrowded group except lingal arch width at second premolar region in the male and buccal arch width at canine, premolar region in the female. (p<0.01) 4. The crowded group revealed smaller arch area than noncrowded group in the female (p<0.01), but there was no significance in the male.

The computerized image analysis is a useful tool for the quantitative assessment of histopathologic findings. In contrast to the usual microscopic examination by pathologists, the computerization should be accompanied with the standardization process of the image. We developed an algorithm to standardize images and to determine the optimal gray level threshold, using a myocardial fibrosis model. Sirius red staining was more convenient for the image analysis than Masson's trichrome staining because of a better contrast with the surrounding structures. To get an optimal measurement, light intensity was standardized at each of the fibrosis, myocardium and background. In this study, the most promising method to determine the degree of fibrosis was that of revising the background without tissue to a gray level of 200, obtaining a green component of the color image, revising the myocardial fiber to 163, and defining a partial ratio as fibrosis index when the gray level threshold was 120. These threshold levels and parameters were determined after drawing the binarization index curves according to the change of the gray level threshold and by the morphological examination of the actual binarization figures overlaid to the original color image. Through these processes we could get a consistent result on the myocardial fibrosis and we expect a similar principle applies when we analyze color images in the histopathologic quantitation by computerized image analysis.

Fibrous hamartoma of infancy (FHI) is an uncommon, benign, solitary intradermal or subcutaneous tumor. It occurs typically in the axillary or shoulder region. The histopathologic examination of affected lesion shows the characteristic elements: dense fibrous tissue, adipose tissue, and primitive mesenchymal tissues. A 15 month-old girl had the multiple, asymptomatic, discrete, and skin-colored tumors that scattered on the scalp. These were present at birth. We report a rare case of FHI occurred on the scalp with multiple and congenital characteristics.

Korean Journal of Urology 1995;36(2):189-194
Currently improving results of hypospadias repair depend on careful application of surgical principles. Optical magnification. microsurgical instruments, fine suture materials, less reactive tubes and bio-occlusive dressings have been used to decrease postoperative complications requiring secondary surgery. We evaluated the effectiveness of microscopic surgery which was performed in 28 children with hypospadias from December, 1991 to June, 1994. Nine patients underwent hypospadias repair before 2 years-old whereas 19 patients after 2 years-old, whose success rate was 78% and 63% respectively. One-stage repair was performed in 19 patients and two-stage repairs in 9 patients, whose success rate was 69% and 67% each other. In chronological review, success rate was 50%, 29%, 77% and 100% in 1991, 1992, 1993 and 1994 respectively, which showed a rapidly increasing success rate. According to dressings and catheters, excellent results were obtained when we used Duodenum dressings and silastic Foley catheters, of which each complication rate was 7% and 0% respectively. In 9 patients(32 %), we experienced 20 surgical complications which included urethrocutaneous fistula (9), meatal stenosis(4) stricture(2) and others(5). The success rate of fistula repair was 61% in initial, 40% in secondary and 33% in tertiary repair. From these data, we think that the use of operating microscope with microsurgical principles and proper postoperative managements can improve success rate of hypospadias repair.

9.Clinical Characteristics and Outcomes after Augmented Medial Rectus Muscle Recession in Patients with Acute Acquired Comitant Esotropia
Journal of the Korean Ophthalmological Society 2023;64(11):1078-1086
Purpose:
To analyze the clinical characteristics of patients with acute acquired comitant esotropia, evaluate the outcomes of augmented medial rectus muscle recession, and propose indicators for determining the appropriate surgical dosage.
Methods:
Data of patients with acute acquired esotropia who underwent medial rectus recession between 2016 and 2022 were retrospectively analyzed. The amount of medial rectus muscle recession was 1-2 mm greater than for other types of esotropia. Surgical success was assessed by reference to the angle of deviation and diplopia status 6 months after surgery. We investigated the amount of additional recession required for favorable surgical outcomes, the characteristics of groups that required augmentation, and changes in surgical amount according to the deviation angle.
Results:
A total of 38 patients were included; the average refractive error was -3.79 ± 3.11 diopters (D). Patient age at the time of surgery was 25.6 ± 18.2 years and the preoperative deviation angle was 38.1 ± 11.5 prism diopters (PD). The amount of medial rectus muscle recession was 6.25 ± 1.4 mm, i.e., 1.2 ± 1.0 mm greater than during other surgeries. The average augmentation was 24.1 ± 18.8%. The motor surgical success rate was 92.1% and the sensory success rate was 97.4%. The required augmentation was 26.9% for those with angles of deviation < 30 PD, 25.5% for patients with angles between 30 and 40 PD, and 20.0% for those with angles > 40 PD. Patients who required augmentation > 25% were older, and the surgical effect was greater as the angle of deviation increased.
Conclusions
To ensure successful surgical outcomes of patients with acute acquired comitant esotropia, it is essential to increase the amount of medial rectus recession compared to that during other surgeries; the average augmentation was 24% in this study.

Pigmented villonodular synovitis is a benign proliferative disorder affecting the synovium. In 1941, Jaffe assembled under the common term of pigmented villonodular synovitis dissimilar lesions described by different names, that issuch as giant cell tumors of synovial tendon sheaths, actual pigmented villonodular synovitis, and villonodular bursitis. (Giant cell tumors of tendon sheaths, which may be localized, most often occurring in fingers, flexor tendons or interphalangeal joints, or diffuse, usually arising in the vicinity of large joints.) Involvement of the temporomandibular joint is very rare. (We report a rare case of pigmented villonodular synovitis of the temporomandibular joint that invaded the mandibular condyle. A 34-year-old man had a large left preauricular (parotid) mass for two years that he had focal facial nerve paralysis, temporal and zygomatic branches. The clinical appearance suggested a parotid tumor. At surgical exploration, a tumor was found to be severely adhered sion to the facial nerve and involving the temporomandibular joint. Histologically, Tthe resected specimen histologically was a proliferative lesion composed of epithelioid histiocytes, spindle cells, and multinucleated giant cells.) The appearance was typical of the family of lesions that includes pigmented villonodular synovitis, bursitis, and tenosynovitis . rewritten as follows: (Giant cell tumors of tendon sheaths, which may be localized, most often occurring in fingers, flexor tendons or interphalangeal joints, and spread to other parts after arising in the vicinity of large joints.) rewritten as follows: (A 34-year-old man had a large left preauricular (parotid) mass for two years and showed focal facial nerve paralysis in the temporal and zygomatic branches. The clinical appearance suggested a parotid tumor. Surgical exploration revealed a tumor that was severely connected to the facial nerve involving the temporomandibular joint. Histologically, the resected specimen was a proliferative lesion composed of epithelioid histiocytes, spindle cells, and multinucleated giant cells.)
