Phyllodes tumors of the breast are rare biphasic fibroepithelial neoplasms that may coexist with breast carcinomas. Herein, we report a case of invasive ductal carcinoma (IDC) within a borderline phyllodes tumor accompanied by extensive ductal carcinoma in situ (DCIS) in the same breast. A 72-year-old woman presented with a palpable lump in the right breast.Mammography showed an oval mass associated with segmental microcalcifications, and breast ultrasound (US) revealed a 2.3 cm oval mass and an associated non-mass lesion. Based on US-guided core needle biopsy, the initial biopsy result of the non-mass lesion suggested DCIS; however, the mass was diagnosed as a fibroepithelial lesion. Preoperative dynamic contrast-enhanced magnetic resonance imaging showed a rim-enhancing oval mass with areas of T2 hyperintensity, accompanied by segmental non-mass enhancement. The mass was highly suspicious for malignancy and was considered imaging-pathology discordant.Subsequently, the patient underwent mastectomy. Histopathological examination of the surgical specimens confirmed a borderline phyllodes tumor with an IDC within the tumor and an extensive intraductal component. The invasive carcinoma component was triplenegative breast cancer. This case highlights the diagnostic challenges of identifying coexisting carcinomas within phyllodes tumors and emphasizes the necessity for increased awareness among radiologists regarding this possibility.

Shock thyroid is a rare manifestation of the CT hypotension complex and can be diagnosed when thyroid and perithyroidal edemas are observed on CT during the onset of shock. Shock thyroid can be a useful CT sign for decompensated shock. This condition is reversible and recovers rapidly with adequate treatment. We present the case of an 84-year-old female with septic shock, exhibiting CT features consistent with a shock thyroid. We also reviewed the clinical and radiological findings reported in the literature. The present case emphasizes that shock thyroid can be an early indicator of impending hemodynamic instability and has important prognostic and therapeutic implications.

BACKGROUND: The aim of this study was to evaluate the clinical outcomes of implants that were placed within the maxillary sinus that has a perforated sinus membrane by the lateral window approach. METHODS: We examined the medical records of the patients who had implants placed within the maxillary sinus that has a perforated sinus membrane by the lateral approach at the Department of Oral and Maxillofacial Surgery of Chonnam National University Dental Hospital from January 2009 to December 2015. There were 41 patients (male:female = 28:13). The mean age of patients was 57.2 ± 7.2 years at the time of operation (range, 20–76 years). The mean follow-up duration was 2.1 years (range, 0.5–5 years) after implant placement. Regarding the method of sinus elevation, only the lateral approach was included in this study. RESULTS: Ninety-nine implants were placed in 41 patients whose sinus membranes were perforated during lateral approach. The perforated sinus membranes were repaired with a resorbable collagen membrane. Simultaneous implant placements with sinus bone grafting were performed in 37 patients, whereas delayed placements were done in four patients. The average residual bone height was 3.4 ± 2.0 mm in cases of simultaneous implant placement and 0.6 ± 0.9 mm in cases of delayed placement. Maxillary bone graft with implant placement, performed on the patients with a perforated maxillary sinus membrane did not fail, and the cumulative implant survival rate was 100%. CONCLUSIONS: In patients with perforations of the sinus mucosa, sinus elevation and implant placement are possible regardless of the location and size of membrane perforation. Repair using resorbable collagen membrane is a predictable and reliable technique.

BACKGROUND: The purpose of this retrospective study was to evaluate the clinical utility of an implant with a sandblasted, large-grit, acid-etched (SLA) surface and internal connection. METHODS: Six patients who received dental implants in the Department of Oral and Maxillofacial Surgery, Chonnam National University Dental Hospital, were analyzed by factors influencing the success rate and marginal bone loss. Factors included patient’s age, sex, implant installation site, whether bone graft was done, type of bone graft materials, approaching method if sinus lift was done, and the size of the fixture. In addition, the marginal bone loss was analyzed by using a radiograph. RESULTS: All implants were successful, and the cumulative survival rate was 100 %. Average marginal bone loss of 6 months after the installation was 0.52 mm and 20 months after the functional loading was 1.06 mm. Total marginal bone resorption was 1.58 mm on average. There was no statistically significant difference in mesial and distal marginal bone loss. CONCLUSIONS: The short-term clinical success rate of the implant with an SLA surface and internal connection was satisfactory. Moreover, the marginal bone loss was also consistent with the implant success criteria.

Sarcoidosis is a somewhat common pulmonary disease, but the concurrence of lung cancer and sarcoidosis in the same patient is very rare. Because sarcoidosis usually presents as mediastinal lymphadenopathies, this concurrence in a lung cancer patient detected radiologically is apt to be misunderstood to be mediastinal metastases, and it is thus considered to be an unresectable disease. We report a case of lung cancer associated with sarcoidosis that developed in a 65-year-old woman who underwent surgery. Radiological studies revealed a 1.9x1.7 cm mass in the left upper lobe with multiple enlarged bilateral mediastinal lymph nodes (2R, 3a, 4R, 4L, 5, 6, 7, 8R). Pathologic findings showed that the mass was a well-differentiated adenocarcinoma and all of the enlarged mediastinal lymph nodes were granulomas without cancer metastasis. We report this case with a review of the literature.

BACKGROUND: HIV serologic testing is essential for blood donor screening, and the test results should be accurate. It is important that clinical laboratories perform quality control, quality management and standardization for obtaining accurate laboratory results. The Korean National Institute of Health, the Division of AIDS and the Center for Immunology and Pathology have all performed annual external quality surveillance assessment (EQS, EQA) with using a 5 sera panel for all the Korean HIV testing laboratories that have collaborated with the Quality Assurance Committee of the Korean Society of Laboratory Medicine since 2005. The results of HIV testing in the clinical laboratories during the year 2007 were analyzed. METHODS: The results for the clinical laboratories that participated in the HIV EQAS during 2007 were collected and analyzed. The HIV test results and questionnaire data were sent to the web site "http://hivqa.nih.go.kr". Three hundred thirty two results from 303 institutions in 2007 were analyzed. RESULTS: The most widely used HIV testing method was an automated chemiluminescent immunoassay, such as the Abbott AxSym and the Architect system or the Roche Elecsys. About 5% of erroneous results were reported among 332 results. The causes of error were mostly clerical errors and specimen errors. CONCLUSION: The current status for HIV testing in Korean clinical laboratories was that fully automated immunoassay analyzers were used along with manual POCT tests.
