Breast metastases from extramammary malignancies are rare. Here, we report a case of breast metastasis from hepatocellular carcinoma (HCC) after breast mass excision in a 63-year-old woman. A new breast nodule was noticed after transarterial chemoembolization, transarterial radioembolization, and stereotactic body radiation therapy for HCC. Breast ultrasound and core needle biopsy were performed to differentiate between the breast tumors. The biopsy result was invasive breast carcinoma, and wide excision of the breast was performed. The final pathological diagnosis was HCC breast metastasis based on histological findings and immunohistochemical staining results. After 9 months of follow-up, HCC and breast metastasis recurred. Despite palliative treatment, the patient died due to complications and general health deterioration. Although breast metastasis due to HCC is very rare, HCC breast metastasis should be considered when a new breast mass is discovered in a patient with a history of HCC for effective treatment and management.

Eosinophilic mastitis is a rare disease in which eosinophils infiltrate the ducts and lobules of the breast, causing mammary inflammation. Although eosinophilic mastitis is a benign condition, it presents similarly to and is often mistaken for breast cancer. Here we report the first case of eosinophilic mastitis in Korea. A 43-year-old woman presented with redness and swelling in her right breast. A breast ultrasound revealed ill-defined isoechoic and hyperechoic areas in the upper half and lower inner quadrant of the right breast combined with axillary level I lymphadenopathy. A histopathological examination by core needle biopsy demonstrated lymphoplasma cell infiltration with eosinophils. A peripheral blood examination revealed an eosinophil count of 5,000/mm³. The patient was treated with oral steroids, antibiotics, and leukotriene receptor antagonists. Four months later, the eosinophil count had returned to normal, and breast ultrasound exhibited marked improvement.

PURPOSE: A retrospective study was conducted to examine the current trend in incidence rates of hip fractures among patients aged 50 years and older in Korea. MATERIALS AND METHODS: A retrospective study was conducted using data on the population, collected by Statistics Korea within the different gender and age groups in total population of Korea from 2007 to 2012. The International Classification of Diseases-10 classification method from the Health Insurance Review and Assessment Service was used to investigate the number of patients with hip fractures, and determine the crude incidence rate (CR) and the age-adjusted incidence rate (AR) for comparison. RESULTS: The CR of hip fractures for patients aged 50 years and older was 178 per 100,000 for men and 350 per 100,000 for women in 2007. In 2012, the CR was 194 per 100,000 for men, and 418 per 100,000 for women. The AR was 197 per 100,000 for men and 281 per 100,000 for women in 2007. In 2012, the AR was 206 per 100,000 for men, and 310 per 100,000 for women. During the observation period, the AR and the CR of hip fractures showed a statistically significant increase. However, the increasing trend has been slowing since its peak in 2010. Comparison of the AR of men and women, showed statistical significance only for women. CONCLUSION: In Korea, the incidence of hip fractures increased significantly from 2007 to 2012. The AR showed statistical significance only for women and the increasing trend is slowing down from 2010.

PURPOSE: The prevalence of allergic rhinitis is rapidly increasing and results in relatively high socio-economic burden on their family and community. However, studies on the economic burden of pediatric allergic rhinitis in Korea are limited. Therefore, we conducted this study to investigate the impact of pediatric allergic rhinitis on economic burden. METHODS: Two hundred sixty two children with allergic rhinitis were enrolled in 6 secondary or tertiary medical centers in Seoul from July to September, 2008. We collected data of the economic burden of allergic rhinitis (direct medical costs, direct nonmedical costs, and indirect costs) by face to face questionnaire survey. We compared the economic burden according to the severity and the duration of allergic rhinitis. RESULTS: The mean age of subjects was 6.54 years, and male were 174 (66.4%). Direct medical costs (10,000 Korean Won/yr) were 177.75, and direct nonmedical costs were 57.92. Although, there was no statistical significance, direct medical costs showed increasing trends in severe allergic rhinitis.(P=0.053) In addition, direct medical costs were positively correlated with duration of allergic rhinitis.(R=0.195, P=0.002). About 17% of the parents who care the allergic rhinitis children experienced the work absence due to their child's illness. CONCLUSION: The economic burdens of allergic rhinitis were positively correlated with the severity and duration of illness. Particularly costs for alternative medicine including oriental medicine were related with severity and duration allergic rhinitis. Therefore, special efforts for education with evidence based treatment strategy are necessary to decrease the economic burden of allergic rhinitis.

Herein we report the case of a 71-year-old woman who complained of fatigue and enlarged right axillary lymph nodes for 18 months. At her first visit, her chest X-ray showed diffuse nodular opacities in both lung fields. Initial excisional biopsy of the axillary lymph nodes showed granulomatous lesions and acid fast bacilli were seen on Ziehl-Neelsen staining. However, even after 15 months of anti-tuberculosis (TB) medication, her right axillary lymph nodes were enlarged. We re-performed an excisional biopsy of the nodes, which showed Hodgkin's lymphoma (HL). A retrograde review of the biopsy before anti-tuberculous medication, revealed HL coexisting with TB. HL and TB cause difficulties in differential diagnosis due to similarities in clinical course, imaging procedures and histopathological analysis of the involved tissue. Therefore, it is important to consider the possibility of concurrent HL and TB when patients who undergo treatment for TB or chemotherapy for lymphoma complain of persistent systemic symptoms or enlarged lymph nodes.

We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

Malignant mesothelioma is the most common primary malignant tumor involving pleura, but its diagnosis is difficult to determine by pathology in addition to the fact that it is rare. We present an unusual case of malignant mesothelioma, which initially presented as large neck mass contrary to the more common presentation of a rind like growth along the pleura demonstrated on imaging and by pathologic findings.

BACKGROUND: We compared two automated Rapid Plasma Reagin (RPR) assay kits with a manual RPR assay kit to evaluate the possibility of using the two automated RPR assays as an alternative to the manual RPR assay for a quantitative monitoring. METHODS: One hundred eighty-five samples were analyzed, including 16 sera from patients with primary, secondary, and latent syphilis. Measured RPR unit (R.U.) values of two automated RPR assay kits, Mediace RPR (Sekisui Chemical Co., Ltd, Japan) and HBi Auto RPR (HBI Co., Ltd, Korea), were compared with the RPR titers of Macro-Vue RPR card test (Becton Dickinson BD Microbiology systems, USA). As a confirmatory test, Anti-Treponema pallidum EUROLINE WB (IgG) and Anti-Treponema pallidum EUROLINE WB (IgM) (Euroimmun, Germany) were used. RESULTS: There was a prozone effect with Mediace RPR at RPR titer (card test) of 1:16, but not with HBi Auto RPR. The R.U. values of the two automated RPR assays did not show proportional increase to the RPR titer. Agreement between manual RPR and two automated RPR assay kits, Mediace RPR assay and HBi Auto RPR assay, were 83.8% and 83.2%, respectively. CONCLUSIONS: The two automated RPR assay kits could not be used as an alternative to manual RPR test for quantitative analysis of RPR titer. As Mediace RPR shows a prozone effect at relatively low RPR titer, caution is needed in the interpretation of the measured values.

PURPOSE: Subclinical prostatitis is a very frequent histologic finding in pathological examinations of prostate surgery specimens. We evaluated the correlation between the symptoms of benign prostatic hyperplasia (BPH) and the grades of inflammation in surgical specimens of patients who had undergone operation for BPH without any evidence of clinical prostatitis. MATERIALS AND METHODS: Seventy five patients with BPH, who had gone through transurethral resection of the prostate (TURP) at our department from March 2004 to May 2007, were retrospectively studied. Of the 75 patients, 57 patients were pathologically diagnosed as having a BPH with prostatitis and 18 patients had the only BPH (group G0). Chronic inflammation was graded as I (group G1: scattered inflammatory cell infiltrate within the stroma without lymphoid nodules), II (group G2: nonconfluent lymphoid nodules) or III (group G3: large inflammatory areas with confluence of infiltrate). The serum prostate-specific antigen (PSA) level, PSA density (PSAD), International Prostate Symptom Score (IPSS) and maximum urinary flow rate were compared among the grades of inflammation. RESULTS: In the patients had undergone TURP, prostatic inflammation was found in 76% (57/75). The storage symptoms of IPSS and PSAD were significantly correlated to the extent of inflammation in each groups (p<0.05). No significant correlations were observed between PSA, size of prostate, voiding symptoms, quality of life (QoL) of IPSS, and maximum urinary flow rate. CONCLUSIONS: The extent of chronic inflammation had considerably more relationship with storage symptoms than voiding symptoms and with the increased PSAD. These findings suggest that the subclinical prostatitis may be one of the factors of storage symptoms of BPH patients and postoperative maintained lower urinary tract symptoms.
