Purpose: Pathologic lesions may occur in an axillary accessory breast (AAB). This study aimed to evaluate the characteristics of tumors arising from AABs and to recommend appropriate treatment. Methods: This retrospective study involved 3,544 women (18–65 years old) with AAB at Damsoyu Hospital in Korea from 2014 to 2023. The patients were divided into an AAB with benign tumors (TAAB) group and an AAB without tumors (AAB) group, and the tumors’ pathologies were reviewed. A core biopsy was performed on tumors with possible malignancy identified by preoperative ultrasonography. All patients underwent complete excision of accessory mammary gland (AMG) tissue, including tumors. The postoperative results were checked 6 months after surgery. Results: Fifty-two out of 3,554 patients had tumors confirmed by preoperative ultrasonography. Preoperative core biopsies were performed on 11 patients. Two patients had malignant tumors (invasive ductal carcinoma) identified by core biopsy.Fifty patients had benign tumors identified by postoperative pathological analysis (46 fibroadenomas, 2 fibrocystic changes, and 2 sclerosing adenoses). Carcinoma in situ was confirmed in 2 patients using postoperative pathological analysis. No patients in either group developed tumors in the axilla during the follow-up period. All patients were satisfied with the axillary pain relief and the disappearance of bulging lesions. Conclusion We recommend a core biopsy if preoperative ultrasonography indicates a possibly malignant tumor. AAB patients may experience tumors, pain, and bulging appearance of an AMG; thus, complete AMG excision is necessary.

PURPOSE: The purpose of this study was to investigate decision patterns to reduce the risks of BRCArelated breast and gynecologic cancers in carriers of BRCA pathogenic variants. We found a change in risk-reducing (RR) management patterns after December 2012, when the National Health Insurance System (NHIS) of Korea began to pay for BRCA testing and riskreducing salpingo-oophorectomy (RRSO) in pathogenic-variant carriers. MATERIALS AND METHODS: The study group consisted of 992 patients, including 705 with breast cancer (BC), 23 with ovarian cancer (OC), 10 with both, and 254 relatives of high-risk patients who underwent BRCA testing at the National Cancer Center of Korea from January 2008 to December 2016.We analyzed patterns of and factors in RR management. RESULTS: Of the 992 patients, 220 (22.2%) were carriers of BRCA pathogenic variants. About 92.3% (203/220) had a family history of BC and/or OC,which significantly differed between BRCA1 and BRCA2 carriers (p < 0.001). All 41 male carriers chose surveillance. Of the 179 female carriers, 59 of the 83 carriers (71.1%) with BC and the 39 of 79 unaffected carriers (49.4%) underwent RR management. None of the carriers affected with OC underwent RR management. Of the management types, RRSO had the highest rate (42.5%) of patient choice. The rate of RR surgery was significantly higher after 2013 than before 2013 (46.3% [74/160] vs. 31.6% [6/19], p < 0.001). CONCLUSION: RRSO was the preferred management for carriers of BRCA pathogenic variants. The most important factors in treatment choice were NHIS reimbursement and/or the severity of illness.

BACKGROUND: This study aimed to evaluate quality of life (QOL) using the EuroQOL-5 dimensions (EQ-5D) index and to examine factors affecting QOL in patients with an osteoporotic vertebral compression fracture (OVCF). METHODS: This ambispective study used a questionnaire interview. Patients over 50 years old with an OVCF at least 6 months previously were enrolled. Individual results were used to calculate the EQ-5D index. Statistical analysis was performed, and factors related to QOL were examined. RESULTS: Of 196 patients in the study, 84.2% were female, with an average age of 72.7 years. There were 66 (33.7%) patients with multilevel fractures. Conservative management was used in 75.0% of patients, and 56.1% received anti-osteoporosis treatment. The mean EQ-5D index was 0.737±0.221 and was significantly correlated with the Oswestry disability index score (correlation coefficient −0.807, P<0.001). The EQ-5D index was significantly correlated with age (Spearman's rho=−2.0, P=0.005), treatment method (P=0.005), and history of fracture (P=0.044) on univariate analysis and with conservative treatment (P<0.001) and osteoporotic treatment (P=0.017) on multivariate analysis. CONCLUSIONS: OVCF markedly lowers QOL in several dimensions for up to 12 months, even in patients who have healed. Treatment of osteoporosis and conservative treatment methods affect QOL and should be considered in OVCF management.

Metastatic squamous cell carcinoma from a cancer of unknown primary (CUP) affecting the intrathoracic lymph node is very rare. We reported a case of metastatic squamous cell carcinoma in the hilar and interlobar lymph node from a patient with CUP and reviewed the associated literature. Abnormal mass in the right hilar area was incidentally detected. A chest computed tomography scan showed a 2.5-cm diameter mass in the right hilum that had changed little in size for 3 years. The patient underwent a right pneumonectomy and mediastinal lymph node dissection. A metastatic squamous cell carcinoma in the hilar and interlobar lymph nodes without a primary lung or other lesion was diagnosed. The patient received adjuvant chemotherapy for a diagnosis of T0N1M0 lung cancer.

Gastric tuberculosis is rare even in the endemic areas of tuberculosis, and can mimic neoplasm by causing elevation of the mucosa with or without ulceration. Here, we report a case in which a 54-year-old female patient admitted for resection of early gastric cancer was found to have coexisting histopathologically and bacteriologically confirmed gastric cancer and tuberculosis.

PURPOSE: The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty. MATERIALS AND METHODS: A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008. The minimum follow-up period was 1 year. The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis. RESULTS: There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters. CONCLUSIONS: Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.

Patellar clunk syndrome after total knee arthroplasty is a complication that causes pain and poping or catching of patella. We experienced a case after mobile bearing total knee arthroplasty that medial synovial tissue was impinged between patella and femoral component and intra-articular fibrotic nodule of superior pole of patella was observed. Also, wear of Polyethylene were observed at anterio side. We resolved the patient symptom after excision of fibrotic nodule, synovectomy of medial synovial hypertrophy, and change of polyethylene. We report this case with literature review.
