Acquired digital fibrokeratoma is an uncommon, solitary, round, firm, more or less hyperkeratotic projection, most frequently situated on fingers or toes but occasionally on the other locations. It arises out of a collarette of slightly raised skin and may have slight or great resemblance to a rudimentary supernumerary digit or may be mistaken for some other more ordinary condition such as an odd cutareous horn. We experienced a case of acquired digital fibrokeratoma on the right second finger in a 25-year-old male. We treated it with total excision.

2.Immunohistochemical and Electron Microscopic Study on the Esohageal Epithelium of the Human Fetus.
Korean Journal of Physical Anthropology 1994;7(1):47-61
To clarify the developmental characteristics of fetal esophageal epithelium especially ciliated cell, expressions of epidermal growth factor receptor (EGFR) and cytokeratin (CK) in fetal esophageal mucosa (16-24 weeks of gestation) were studied immunohistochemically, and ultrastructure of the ciliated cells was also observed. The expressions of EGFR and CK were identified in labelled streptoavidine biotin immunohistochemical method. Primary antibodies used were EGFR (Ab-4) which is affinity-purified from hyperimmune rabbit sera (Oncogene Science) and monoclonal mouse anti-human cytokeratin (DAK0-CK, MNFl16). The esophageal lumen was lined with stratified ciliated columnar epithelium between 16 and 24 weeks of gestation. The pattern of expression Of EGFR was different with gestational age and epithelial layer. The ciliated cell exhibited variable staining intensity for EGFR at 16 weeks. Some were stained intensively, and others were stained faintly. Number of ciliated cells stained intensively were gradually increased, and most of them were strongly stained at 24 weeks. The superficial non-ciliated cells, however, showed relatively constant staining property of moderate to intense between 16 and 24 weeks. EGFR immunoreactivity was minimal in the basal and intermediate cells at 16 weeks, but became more intense at 24 weeks. CK immunoreactivity in the ciliated cells between 16 and 24 weeks was similar to that of EGFR immunoreactivity. On the other hand, superficial non-ciliated cells were intense for CK staining at 16 weeks, but were very weak to negative at 24 weeks. CK immunoreactivity was intense in basal and intermediate cells between 16 and 24 weeks, but it was almost negative in the some cells of intermediate layer, especially beneath negatively stained non-ciliated cells, at 24 weeks. In electron microscopy, ciliated cells had well organized cilia and dense granules close to Golgi apparatus between 16 and 24 weeks. The cells apparently active in ciliogenesis were also observed. These cells had short microvilli, many centrioles, and dense granules close to Golgi apparatus. The non-ciliated cells contained numerous clear vesicles adluminally clustered at 16 weeks, while they had many dense vesicles of about same size of clear vesicles at 24 weeks. These results demonstrate the expressions of EGFR and CK in esophageal epithelium of human fetus between 16 and 24 weeks of gestational ages, and suggest that the ciliated cells are still proliferative at 24 weeks.

Korean Journal of Dermatology 1983;21(4):483-487
Eccrine spiradenoma is clinically characterized by a solitary, movable, tender noduie occurring most frequently on the ventral surfase of the upper body. A striking symptom is paroxysmal pain. Histopathologically, the encapsulated lobules of the tumor are composed of masses of basophilic cells, usually arranged in whorls, cords, and pseudogland.s. Within the whorls and pseudoglands, two types of celIs are notedperipheral intensely staining cells and central pale-staining cells. We describe herein a patient with an indolent eccrine spiradenoma, which had been diagnosed histopathologically.

BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

BACKGROUND: Patients with sinus rhythm, the left atrial appendage(LAA) appeared as a vigorously contracting structure and the blood flow patterns of LAA showed biphasic configuration. However, patients with AF rhythm the blood flow showed irregular or no configuration in doppler echocardiographic study. The purpose of this study is to evaluate relationship between the blood flow patterns of LAA with the presence of spontaneous contrast(SC) and thrombi in LAA. METHODS: We performed TEE and TTE simultaneously to 58 consecutive patients who had native mitral valve disease or mitral prosthesis. Spontaneous contrast(SC) and the presence and location of LAA thrombi were evaluated during TEE and left atrial dimension(LAD) & ejection fraction(EF) were evaluated during TTE. We divided the whole subjects into three groups according to the blood flow patterns ; regular pattern(Group 1), irregular pattern(Group 2), no flow pattern(Group 3). RESULTS: 1) Blood flow within the left atrial appendage is divided with three groups among of them, atrial fibrillation have two blood flow patterns. 2) Peak prositive & negative flow velocity within LAA in AF rhythm groups were slower than normal sinus rhythm group.(p<0.01) 3) Left atrial dimension in group 3 is significantly larger than others groups.(p<0.01) 4) Spontaneous contrast(SC) with LAA could be detected in 2(6.8%) of the 29 patients of group 1, 6(31.5%) of the 19 patients of group 2, 10(100%) of the 10 patients of group 3. Incidence of SC within LAA in group 3 is significantly higher than others groups. 5) LAA thrombi could be detected in 1(3.4%) of the 29 patients of group 1, 1(5.2%) of the 19 patients of group 2, 3(30%) of the 10 patients of group 3. Incidence of LAA thrombi is significangly higher than other groups. CONCLUSIONS: We can suggest that blood flow within LAA is divided into three groups according to the blood flow patterns, and spontaneous contrast and thrombi in LAA were closely related with the blood flow pattern.

PURPOSE: Long-term follow-up results of concurrent bilateral or unilateral cementless hip arthroplasty were compared. MATERIALS AND METHODS: Forty eight and 49 patients with concurrent bilateral and unilateral hip artrhoplasties who had more than a 17-year follow-up time were selected. At final follow-up, mean ages were 69.1 and 66.7 years old in the bilateral and unilateral groups, respectively. Mean follow-up times were 21.5 and 22.4 years in the bilateral and unilateral groups, respectively. Clinical results were attained using Harris hip score and standardized anteroposterior and lateral view X-rays. RESULTS: The bilateral group had mean Harris scores of 44.3(standard deviation 3.78) preoperatively, and 81.2 (10.75) at final follow-up. For the unilateral group, the mean scores were 46.5(3.27) preoperatively, and 80.1 (12.05) at final follow-up. At final follow-up, an acetabular cup was securely located in 78.9% and 82.8% of the bilateral and unilateral groups, respectively, and all cases showed firm fixation of the femoral stem in both groups. Osteolysis around the cup and stem were found in 26.3% and 31.4% of the bilateral group and 16.6% and 17.1% of the unilateral group, respectively. Polyethylene wear rate was 0.17 mm/yr and 0.16 mm/yr in the unilateral and bilateral groups, respectively. Using the Kaplan-Meier method, 17-year survival rates for cup and stem were 78% and 89% in the bilateral group, respectively, and 78% and 86% in the unilateral group, respectively. CONCLUSION: In 17-year long-term follow-up, concurrent bilateral hip arthroplasty was insignificantly different clinically and radiologically from the result of unilateral hip arthroplasty.
