Alveolar soft part sarcoma is a clinically and morphologically distinct soft tissue tumor that was first defined and named by Christopherson et al in 1952. Since 1953, alveolar soft part sarcoma invading bone have been reported sporadically. We experienced a case of alveolar soft part sarcoma with metastasis to femoral shaft, which was treated by wide resection & vascularized fibular strut graft.

Classic Kaposi's sarcoma is a human herpesvirus-8 associated with a multicentric lymphoangioproliferative tumor primarily arising in the lower extremities, but rarely in the head and neck. We herein report a 63-year-old man with primary classic Kaposi's sarcoma on the face. He presented with asymptomatic, erythematous papules on the nasal ala which had been noticed 2 months earlier. Histopathologic examination and nested polymerase chain reaction analysis in the tissue disclosed typical features of Kaposi's sarcoma.

Objectives: . To determine the appropriate anatomical borders of implantation on the temporal bone in a cadaver study, and to develop a simplified surgical technique for Baha Attract implantation through a small incision along the hairline using anatomical evidence and a navigation system. Methods: . In a cadaver study, 20 human adult dry skulls were used to find flat areas of the temporal bone for Baha Attract magnet implantation. Four borders of the “optimal surgical site” were defined: Asterion line, occipitomastoid suture line, sigmoid sinus line, and digastric groove line. In three patients, we implanted the Baha Attract according to the newly developed surgical procedure and validated the feasibility of this technique with a navigation system. Results: . We identified the appropriate position of the implant on the temporal bone, suggesting a simplified surgical technique for Baha Attract with a small incision. We determined the spot of implantation, and the implants were inserted through a small surgical incision (<2.5 cm) under local anesthesia; the procedure lasted approximately 30 minutes. Conclusion . The optimal surgical site of the temporal bone is a safe and easily accessible location for implantation of the Baha Attract.

BACKGROUND: Many different dermatologic manifestations can accompany a variety of systemic diseases such as rheumatic disorders. The number of patients who have skin lesions related to systemic diseases is steadily increasing. In such cases, dermatologic consultation can be important to diagnosis and treatment. OBJECTIVE: The purpose of this study was to analyze patterns of skin manifestations in rheumatic diseases. METHODS: We did an analysis of data for 192 inpatients who were referred by the department of rheumatology and consulted by the department of dermatology between May 1, 2005 and April 30, 2009. We retrospectively reviewed their medical records and noted age, sex, reasons for dermatologic consultation, diagnosis of the dermatoses and changed diagnosis after the consultation. RESULTS: The percent of patients who were referred by the department of rheumatology and consulted by the department of dermatology was 15.5% (192 consulted inpatients/1,242 rheumatologic inpatients). The most frequent age group was those in their 5th decade of life (23.0%) and the male to female ratio was 1:2.15. Consultations for dermatologic manifestations unrelated to systemic or rheumatic diseases were the most common reason for consultation (62.0%). Dermatoses related to systemic or rheumatic diseases were the 2nd most common reason of consultation (34.9%). Infectious diseases were the most common dermatoses (46 cases). There were 13 cases where there was a diagnosis of undetermined dermatoses and changed diagnosis after dermatologic consultation. CONCLUSION: Analysis of consultations from inpatients referred by the department of rheumatology to the department of dermatology indicates that there is a substantial number of patients that have skin manifestations of their rheumatic diseases.

A 31-year-old woman presented with 2 year history of multiple, pinhead-sized erythematous papules, which had become coalescent in linear arrangement from the forehead to the left nasal ala. Histopathologically, the lesion showed hyperkeratosis, spongiosis and inflammatory cell infiltration around the skin appendages, and was therefore diagnosed as facial lichen striatus. The patient had been treated with an intermittent topical steroid application for about two years, but this had not been effective. However, application of 0.03% tacrolimus ointment showed dramatic improvement.

It is uncertain whether small congenital melanocytic nevi is associated with an increased risk of melanoma. However, if a small congenital melanocytic nevus develops suspicious changes, becomes symptomatic, or is irregular, then an excisional biopsy may be justified. We report an interesting case of a 33-year-old man who was diagnosed with melanoma in situ, arising in a small congenital melanocytic nevus with a cyst. Histologic examination revealed that intradermal nests of nevus cells had surrounded the epidermal cyst. In the basal cell layer, and in the wall of the epidermal cyst, atypical melanocytes were observed.

A 35-years-old man was hospitalized with gene-ralized edema. 6 months ago, the patient was operated by radical subtotal gastrectomy for advanced gastric adenocarcinoma. The patient presented with multiple liver metastasis and the massive proteinuria. The patients renal biopsy revealed minimal change nephrotic syndrome and treated with prednisolone and diuretics. The patient was improved clinical symptome and decreased 24 hours urine protein. In literature reviewed, gastric carcinoma was not associated with minimal change nephrotic syndrome. We experienced advanced gastric carcinoma associated with minimal change nephrotic syndrome, thus we report it.

PURPOSE: We conducted a retrospective analysis to determine if adjuvant chemotherapy prolongs overall survival in patients with pathologic stage IB lung adenocarcinoma who had undergone complete resection and were defined as high-risk by a newly developed recurrence risk scoring model. MATERIALS AND METHODS: Patients who underwent curative resection for stage IB lung adenocarcinoma were analyzed with a newly developed recurrence risk scoring model and divided into a low-risk group and a high-risk group. The patients in the high-risk group were retrospectively divided into two groups based on whether they underwent adjuvant chemotherapy or observation. Recurrence-free survival and overall survival were compared between these two groups. RESULTS: A total of 328 patients who underwent curative resection between 2000 and 2009 were included in this study, of whom 110 (34%) received adjuvant chemotherapy and 218 (67%) underwent observation without additional treatment. According to our risk model, 167 patients (51%) were high-risk and 161 (49%) were low-risk. The 5-year recurrence-free survival rates and overall survival were 84.4% and 91.5% in low-risk patients and 53.9% and 74.7% in high-risk patients (p < 0.001). In high-risk patients, the 5-year overall survival rates were 77% among patients who underwent observation and 87% among those who underwent adjuvant chemotherapy (p=0.019). CONCLUSION: Adjuvant chemotherapy prolonged overall survival among high-risk patients who had undergone complete resection for stage IB lung adenocarcinoma.

PURPOSE: The purpose of this study was to analyze the CT findings of hepatoblastoma before and afterchemotherapy, and to compare them with surgical and pathologic features. MATERIALS AND METHODS: Twelvehepatoblastoma patients underwent chemotherapy prior to surgery; in all cases, CT scanning was performed beforeand after chemotherapy. We reviewed the findings with special attention to changes in tumor volume, the extent andpattern of contrast enhancement, the extent of low-attenuation area in the tumor, the presence of a septum, andcalcification or ossification within the mass before and after chemotherapy. Post-chemotherapy CT findings werecompared with operative and pathologic findings. RESULTS: After chemotherapy, the volume of the tumor massdecreased in all patients, and the extent of involved segments decreased in nine(75%), the non-enhancing areawithin the mass, on the other hand, increased in nine (75%). On pre-chemotherapy CT, calcifications were detectedin seven patients(58%), and on post-chemotherapy CT, in nine (75%); the extent of calcification increased in sevenpatients. On the basis of CT findings, viable tumor and necrosis areas could not be distinguished. Massivecalcification or an osteoid mixed with loose connective tissue was noted in the mesenchymal component of thetumor; the whirling pattern of enhancement within the area of low density asen on CT scanning corresponded toosteoid mixed with loose connective tissue, which contained rich blood vessels. CONCLUSION: We describe the CTfindings of hepatoblastoma both before and after chemotherapy, highlighting the changes which occurred. Anunderstanding of these changes is helpful for the proper management of this condition.
