Friction melanosis is frequently developed in thin, young woman, on thc covered skin of spinc, rib, elbow, knee and tibia. These lesions range from brown to rcddish-brown in color, appear in either band shapes or reticular patterns, and exhibit no overt syrnptoms. They do not show any inflamatory changes, and the skin remains smooth. According to histopathological findings, the main changcs arc perivascular melanophages on the papillary derrnis and upper dermis, and also increased melanin granules on the basal layer. The following case concern a relatively thin 20-year-o1d female patient. She had a syrwptoniless brown color changcs above the ribs of back, growing in dircction of the ribs for a period of three years. This change was band shaped, but there were no signs of inflammatory reaction, leaving the skin smooth. A biopsy was performed on the relevant tissue, and clinical-histopathological analysis was resulting in diagnosis of friction melanosis.

She describe herein two cases of eccrine spiradenoma. One is an indolent and the other is painful or tender multiple small nodules distributed in a zosteriform pattern. Histopathologically, the encapsulated lobules of the tumor are composed of two types of cells, intensely staining cells and pale staining cells, usually arranged in whorls, cords, and pseudoglands. In the second case, enzyme histochemical staining and electron microscopic examination have been done and are compared with other cases in the literature.

A 33-year-old man had multiple, dome shaped, pin-head sized, hard papules on the center of face and pigeon's egg sized hard tumors on the left upper arm and the trunk. The histopathological findings of the skin biopsy specimens from face and left upper arm showed tumor islands composed of basophilic cells of the same sppearance as basalioma cells, arranged in a lacelike and solid aggregates, without horn cysts.

We observed the clinical and histopathologic characteristics of acquired, bilateral nevus of Ota-like macules in each 80 and 23 patients. The results were as follows: 1. All patients were female and the peak age of onset was third decade with an a,verage age of 27.4 years. 2. The colors of lesions were slate, brown, dark brown, and blue black in order of freguency. 3. The lesions were most comrnonly observed in the malar area and alae nasi. 4. Three patients had family history of acquired, bilateral nevus of Ota-like :macules. 5. Histopathologically pigment-bearing cells, bipolar or irregular in shape, were found mostly in the upper- and mid-portion of the dermis. The melanocytes showed weakly positive dopa reaction. 6. In electron microscopic observation, these pigrnent-bearing cells contained many singly dispersed melanosomes in stage 3 and 4 of melanization and wece surrounded by an extracellular sheath.

PURPOSE: Our objective was to evaluate mammographic findings of breast cancer in men. MATERIALS AND METHODS: This study includes 9 man with breast cancer diagnosed pathologically by radical mastectomy. Clinical and pathologic data were obtained by review of patients' medical record. Mammograms were analysed retrospectively. RESULTS: Of the 9 patients, eight had masses with spiculated margin or schirrous pattern with irregular margin. One patient had no specific evidence of breast cancer mammographically. Microcalcifications were seen in three patients, these calcifications were irregular in shape and were clustered. Of the 8 cases, four patients had the masses at the right breast, four at the left breast. Locations of breast cancer were subareolar(n=4) and were eccentric(n=4) from the nipple. The most common location was the upper outer quadrant. On histologic evaluation, 7 cases were infiltrating ductal carcinomas, one case was mucinous adenocarcinoma, and the remainder was proved as combined form of intraductal and infiltrating ductal carcinoma. Axillary lymph node metastasis were found in 4 cases. CONCLUSION: Mammographic findings of male breast carcinoma were that of subareolar or eccentrically located mass. Calcifications were same to the patterns of calcification as female breast cancer.

The purpose of this study was to determine the distribution, prevalence and relationship of the localized periodontitis of root fusion in maxillary and mandibular molars. One hundred patients who had eight maxillary and mandibular molars(third molars excluded) were consecutively selected for the study subjects. The subjects provided a total of 800 molars, i.e., 400 maxillary and 400 mandibular molars. A decision about root fusion was made on the radiographic examination. Probing depth, plaque index, gingival index and mobility were measured. The results were as follows. 1. 15.9% of the molars had a fused root. 22% of the maxillary molars and 9.8% of the mandibular molars had a fused molars. 2. In maxillary molars, the results of probing depth, plaque index, gingival index, mobility are more higher in test group than in control group, and there was a significantly difference except plaque index of maxillary first molars group(p<0.01). 3. In mandibular molars, the results of probing depth, plaque index, gingival index, mobility are more higher in test group than in control group, and there was a significantly difference(p<0.01). As a result of this study, it can be concluded that, in management of molars with a root fusion, we should detect the molars through the precise radiographic examination, early periodontal treatment and systematic treatment plan should be chosen. And postoperative continuing supportive periodontal therapy is needed.

PURPOSE: The aim of this study is to assess the long-term results of laparoscopic common bile duct exploration (LCBDE) and validate its effectiveness as a primary treatment modality for CBD stone. METHODS: A retrospective review of the medical records of 157 patients who underwent LCBDE from 1997 to 2011 was conducted. All LCBDE were performed by choledochotomy. Clinical demographics, operative outcome, recurrence rate of CBD stones, and long-term bile duct complications were analyzed. The mean follow-up period was 51.9 months. RESULTS: LCBDE was completed in 152 patients (96.8%) and 5 patients (3.2%) had open conversion. The male/female ratio was 78/79 and mean age was 67.3 years. Stone clearance was successful in 149 of 152 patients (98.0%). Nonlethal complications were noted in 11 patients (7.2%), including bile leakage in 6 patients (3.9%). Recurrent CBD stones developed in 9 of 152 patients (5.9%). Preoperative endoscopic sphincterotomy (P = 0.492) and choledochotomy repair type (T-tube drainage vs. primary closure, P = 0.740) were not significantly related to stone recurrence. There were no signs of any type of biliary injury or stricture observed in any of the patients during the follow-up period. CONCLUSION: LCBDE can be performed without increased risk of long-term complications such as bile duct stricture and recurrent CBD stones. LCBDE is a safe and effective treatment option for choledocholithiasis in terms of long-term outcome as well as short-term outcome.
