We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

BACKGROUND: Nevus sebaceus of Jadassohn is a complex anomaly involving the epidermis, dermis, apocrine glands and hair follicles, as well as the sebaceous glands, and a variety of benign and malignant tumors and neurologic abnormalities may be associated with it; however, only a few studies on it have been reported in the Korean literature. OBJECTIVE: The objectives of this study was to document clinical and histopathologic features of nevus sebaceus in Koreans and compare them to those in the previously reported studies. METHOD: Clinical records and histopathology of 53 cases of nevus sebaceus diagnosed at Ewha Womans University Tongdaemun Hospital during a period of 18 years were reviewed and analyzed. RESULTS: The average incidence rate of nevus sebaceus among new patients was 0.03%. The male-to-female ratio was 1.04 and the average age at visit, 16.5 years. The lesions had been present since birth or had developed before age 10 in 85% of the cases. A11 lesions were situated on the head, and the most common site was the scalp. Linear 1esions (20.8%) were mostly facial lesions. Histopathologically, the incidence of sebaceous and apocrine glandular hyperplasia was most notable in the 13-18 and over-18 age groups. The sebaceous glands showed small punched out defects or "holes" in 24.5%; ectopic apocrine glands were found in 24.5 %. Mature hair follicles were absent or greatly reduced in number in 75.5%. Acanthosis nigricanslike pattern of acanthosis and mild papillomatosis were the dominant changes in the epidermis. Hyperplasias and neoplasms were associated in 15.1%, which included 5 cases of primitive follicular induction and 1 trichoblastoma. CONCLUSION: In this series, no examples of malignant neoplasms were identified; however, an early total excision before age 13 is recommended since a variable "deficit malformation" of the follicles with hyperplasia of the epidermis and sebaceous glands becomes more prominent after that age.

Annals of Dermatology 2000;12(3):202-205
A 22-year-old woman with no history of trauma or other diseases presented with a slowly enlarging firm nodule with a central pointed opening on the right chest. An excisional biopsy revealed a pilomatricoma associated with an epidermoid cyst. Histopathologically, an epidermoid cyst located in the deep dermis was lined mostly by keratin-forming stratified squamous epithelium but focally had columns of shadow cells that projected from the epithelial lining of the cyst into the lumen. The lumen also contained masses of shadow cells, unattached to the epithelial lining. In the stroma surrounding the cyst, numerous masses of shadow cells with giant cell reaction and focal calcification were seen, which were in turn surrounded by a connective tissue capsule. These features are similar to those seen in infundibular cysts associated with Gardner's syndrome. Since epidermoid cysts and pilomatricomas originate in common from the pilosebaceous unit and pilomatricomas begin as infundibular matrix cysts, we suggest that they can occur simultaneously, although rarely, in a healthy person.

Annals of Dermatology 2000;12(3):179-184
BACKGROUND: Pilomatricoma is a rare benign follicular tumor in Asians OBJECTIVE: purpose of this study was to assess the clinical and histopathological features of the tumor. METHODS: The hospital charts and slides of 13 patients with pilomatricoma over a 12-year period at Ewha Womans University Tongdaemun Hospital were retrospectively reviewed. RESULTS: The age of patients ranged from 5 to 76 years with a mean of 21.5 years. The maleto-female ratio was 1:3.3. Seventy-seven percent of the tumors were located on the upper and lower extremities, followed by the face and neck. Most tumors appeared as a pea-sized hard movable skin-colored nodule. At histopathologic level, the most common morphological stage was the early regressive stage (stage 3), followed by late regressive (stage 4), fully developed (stage 2), and early (stage 1) stages. Foreign body giant cells, calci6cation, ossification were seen in 69.2%, 84.6%, and 7.7%, respectively; giant cells and inflammatory infiltrate were mostly seen in stage 3 tumors, calcification in stage 3 and 4 tumors, and ossification, only in the sole stage 4 tumor. Anetodermic changes of overlying dermis were seen in 2 cases (15.4%). CONCLUSION: The various histopathologic features of pilomatricoma can be explained by its chronological, morphological stages.Most pilomatricomas present for longer than 6 months are already in stage 3, and one can expect the histopathological features accordingly.

E-cadherin is a calcium-dependent epithelial adhesion molecule which plays a role in the initial step of invasion of cancer cells. The step that follows the migration of separated tumor cells is a proteolytic lysis of basement membrane and extracellular matrix by protease of epithelial and endothelial cells such as matrix metalloproteinase (MMP). Vascular endothelial growth factor (VEGF) is known to be an endothelial cell-specific powerful mitogen as well as a vascular permeability factor. This study is aimed to evaluate the correlation between expression of these factors and pathologic or clinical variables and the roles and prognostic significance of those factors in squmous cell carcinoma and adenocarcinoma of the lung. Immunohistochemical stains were performed for E-cadherin, MMP-2, and VEGF in surgically resected specimens from 90 patients with squmous cell carcinoma and adenocarcinoma of the lung. Mean age of the patients was 59.7 years. Histologic type was categorized into 56 cases of squamous cell carcinoma and 34 cases of adenocarcinoma. Mean survival period of the 35 patients was 54 months. The immunohistochemical stains for E-cadherin, MMP-2, and VEGF revealed positive reaction in 67 cases (74.4%), 43 cases (47.8%), and 34 cases (37.8%), respectively. The expression of E-cadherin was higher in adenocarcinoma (82.4%) than in squamous cell carcinoma (69.6%). MMP-2 was expressed in the tumor cells, especially those invading into the surrounding stroma. The expression of MMP-2 was significantly correlated with the survival rate (p<0.05). The expression of VEGF in the tumor cells was significantly higher in cases with lymph node metastasis (p<0.05). In conclusion, these findings suggest that the expression of MMP-2 and VEGF predict poor prognosis of patients with squmous cell carcinoma and adenocarcinoma of the lung and that VEGF may play a role in tumor metastasis.

BACKGROUND: It is a popular notion that cutaneous ageing includes two distinct phenomenon; true ageing, a universal presumably inevitable change attributable to the passage of time alone, and photoageing, changes attributable to chronic habitual sun exposure that are neither universal nor inevitable. Numerous investigations with experimental animals, in vitro skin models have been conducted, although, few histological studies to date have attempted to announce fundamental morphological changes with innate ageing. OBJECTIVE: We compared skin derived from the breast of old and young persons using light microscopy to discern structural changes in epidermal and dermal morphology with advancing age. METHODS: The histological, immunohistochemical studies were performed with normal skin sections of thirty donors who were diagnosed with breast cancer. They were classified into three age cohort groups; nine into group I (22 to 38), twelve into group II(40 to 52), and nine into group III(54 to 87). We chose the breast as an area that might closely resemble intrinsically aged skin. This region is relatively shielded from photoageing by its anatomical location. Analysis of data was performed using the Kruskal-Wallis and ANOVA test for dermal parameters based on a 5-point rating scale, and a simple regression test for a positive rate of immunoreactants. Results : 1. Light microscopic appearance of aged skin revealed a more flattened epidermis than young skin. There was no trend for an increase in epidermal melanin content per unit area on Fontana-Masson staining. There was an age-associated decrease in the Ki-67 positive rate(p<0.001), the density of Ki-67 positive cells declined approximately 1.16% per decade in photoprotected skin(p<0.001). The number of S-100 positive cells declined approximately 4.4/mm width along the dermo-epidermal juction per decade in photoprotected skin(p<0.001). The expression of differentiation markers(keratin 1, involucrin, filaggrin, loricrin) were not different among the three age cohort groups. 2. With advancing age, there was an attenuation in the number and diameter of elastic fibers in the papillary dermis and an increase in the number and straightness of the same fibers in the reticular dermis. The collagen fibers are arranged in sparse bundles in disarray, and/or aggregates of loosely woven, straight fibers in the aged skin. There was an apparent, age-related decrease in the stainability of ground substances in the papillary dermis on colloidal iron staining. Conclusions : Our data documents semi-quantitative differences among three groups in intrinsically aged breast skin and provide the framework for future research to evaluate the ageing process.

Two cases of old unreduced radial head dislocation in children were experienced in this hospital. These were the results of neglected Monteggia fracture. Dislocated radial heads were reduced under direct vision and the anular ligaments were reconstructed. Follow up study taken 9 months and 6 years respectively after operation revealed excellent elbow motion including pronation and supination. The radial nerve palsy which had been developed in one of the two patients after injury was recovered spontaneously after reduction of the radial head without opening of the Arcade of Frohse. Then we are reporting these cases with a review of the literature.

A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.
