We reviewed the clinical features and the skin biopsy slides of 27 patients who were diagnosed as PLEVA clinically or histapathologically in order to evaluate the clinical characteristics and the specific histopathological findings of PLEVA. The results were as follows : l. 13 of these 27 cases(48%) were confirmed as PLEVA. 2. PLEVA was more frequent in males(85% ), most of whom were young adults. 3. In most cases of PLEVA, the predilection site was on the trunk and extremities, and mild pruritus was a characteristic complaint. 4. Most cases of PLEVA were treated with tetracycline or PUVA therapy with temporary remission, but this therapy did not decrease the rate of recurrence. 5. Some histopathological findings previously described as typical in PLEVA(eg, trapped RBC in the epidermis, exocytosis of lymphocyte, dermal hernorrhage and lymphocytic perivasculitis) seemed not to be specific and were often seen in a variety of other dermatoses. 6. The histopathological findings of linear parakeratosis(85%) and dyskeratotic cells in the middle and upper epidermis(92% ) seemed to be significant findings for PLEUA. 7. The above mentioned histopat,hological findings for PLEVA were frequently found from the vesicular lesions or necrotic hemorrhagic papules.

OBJECTIVE: The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS: A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 mm. Under 100 g of intrusive force, initial displacement of the individual teeth in three directions and the degree of labial tilting were measured. RESULTS: The degree of labial tilting increased with reduced alveolar bone height under the same load. When a miniscrew was inserted between the two central incisors, the amounts of medial-lateral and anterior-posterior displacement of the central incisor were significantly greater than in the other conditions. When the miniscrews were inserted distally to the canines and an intrusion force was applied distal to the lateral incisors, the degree of labial tilting and the amounts of displacement of the six anterior teeth were the lowest, and the maximum von Mises stress was distributed evenly across all the teeth, regardless of the bone loss. CONCLUSIONS: Initial tooth displacement similar to pure intrusion of the six maxillary anterior teeth was induced when miniscrews were inserted distal to the maxillary canines and an intrusion force was applied distal to the lateral incisors. In this condition, the maximum von Mises stresses were relatively evenly distributed across all the teeth, regardless of the bone loss.

We report a case of factitial panniculitis in a 50-year-old female patient who had multiple variable sized subcutaneous nodules on area accessible to the hands and disappeared by only prohibition of habitual skin massage. Histologic findings showed mostly lobular panniculitis with hemosiderin deposits, many foamy histiocytes and pseudomicrocysts.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.

Pseudoepitheliomatous, keratotic and micaceous balanitis is a rare distictive clinical entity that represents a histologic spectrum ranging from hypertrophic hyperpalstic penile dystrophy to verrucous carcinoma. This condition is thought to be a malignant growth potential by resistance to treatment and its tendency toward local recurrence. We report two cases with similar clinical presentation of hyperkeratotic plaque and micaceous scaly patches on the glans penis that were compatible with pseudoepitheliomatous, keratotic and micaceous balanitis. Histopathologically, case 1, 48 year-old male was progressed to squamous cell carcinoma and case 2, 78 year-old male, was shown pseudoepitheliomatous hyperplasia without malignant changes.

A granular cell tumor (GCT) is a relatively rare benign tumor that has been seldom reported since Abrikossoff first described it as a granular cell myoblastoma in 1926. While GCTs can occur anywhere in the human body, they are very rarely observed in the gastrointestinal tract and are especially rare in the large intestine. Most GCTs are small and asymptomatic and are often found by endoscopy, upper gastrointestinal series, and autopsy. We report two cases in which a submucosal tumor in the cecum was accidentally discovered by colonoscopy and was subsequently removed by colon polypectomy and endoscopic mucosal resection. Immunohistochemical analysis of the samples confirmed both cases as GCT. The literature review and reports of other growths in the gastrointestinal tracts support the necessity for proper identification of GCTs within the body to differentiate them from more malignant tumors.
