Purpose: Erysipelas is a bacterial infection of the dermis and hypodermis, mostly of streptococcal origin, and erysipelas of upper extremity following breast cancer treatment has never been reported in the Korean literature. Methods: 39-year-old female presented to our hospital complaining of fever and painful swelling of her left upper extremity. She had a history of breast cancer and was treated with breast conserving surgery with axillary lymph node dissection, chemotherapy, and radiation. On physical examination, her left upper extremity showed vesicle, bullae, local heatness and erythema with well-defined margin. With these distinctive features of a skin lesion, we gave a diagnosis of erysipelas and started treatment with intravenous antibiotics. Results: Resolution of the signs and symptoms of erysipelas occurred after 7 days of treatment. Conclusion: The diagnosis of erysipelas with distinctive feature of skin lesion is essential and we emphasize that the prevention of any trauma are very important in these patients for prophylactic measures.

Purpose: This aim of this study is to analyze the dosimetric difference between intensity-modulated radiation therapy (IMRT) using 3 or 5 beams and MSF in the radiotherapy of the left breast. Materials and Methods: We performed a comparative analysis of two radiotherapy modalities that can achieve improved dose homogeneity. First is the multistatic fields technique that simultaneously uses both major and minor irradiation fields. The other is IMRT, which employs 3 or 5 beams using a fixed multileaf collimator. We designed treatment plans for 16 early left breast cancer patients who had taken breast conservation surgery and radiotherapy, and analyzed them from a dosimetric standpoint. Results: For the mean values of $V_{95}$ and dose homogeneity index, no statistically significant difference was observed among the three therapies. Extreme hot spots receiving over 110% of the prescribed dose were not found in any of the three methods. A Tukey test performed on IMRT showed a significantly larger increase in exposure dose to the ipsilateral lung and heart than multistatic fields technique (MSF) in the low-dose area, but in the high-dose area, MSF showed a slight increase. Conclusion: In order to improve dose homogeneity, the application of MSF, which can be easily planned and applied more widely, is considered an optimal alternative to IMRT for radiotherapy of early left breast cancer.

Purpose: Deep inspiration breath hold (DIBH) is a well-established technique that enables efficient cardiac sparing in patients with left-sided breast cancer. The aim of the current study was to determine if DIBH is effective for reducing radiation exposure of of liver and other organs at risk in right breast radiotherapy (RT). Materials and Methods: Twenty patients with right-sided breast cancer were enrolled in this study. Three-dimensional conformal RT plans were generated for each patient, with two different computed tomography scans of free breathing (FB) and DIBH. Nodes were contoured according to the Radiation Therapy Oncology Group contouring guidelines. Dose-volume histograms for the target volume coverage and organs at risk were evaluated and analyzed. Results: DIBH plans showed significant reduction in mean liver dose (5.59 ± 2.07 Gy vs. 2.54 ± 1.40 Gy; p = 0.0003), V_20Gy (148.38 ± 73.05 vs. 64.19 ± 51.07 mL; p = 0.0003) and V_10Gy (195.34 ± 93.57 vs. 89.81 ± 57.28 mL; p = 0.0003) volumes compared with FB plans. Right lung doses were also significantly reduced in DIBH plans. Heart and left lung doses showed small but statistically significant improvement with application of the DIBH technique. Conclusion: We report that the use of DIBH for right-sided breast cancer significantly reduces the radiation doses to the liver, lungs, and heart.

Superficial inferior epigastric artery (SIEA) flaps represent a useful option in autologous breast reconstruction. However, the short-fixed pedicle can limit flap inset options. We present a challenging flap inset successfully addressed by de-epithelialization, turnover, and counterintuitive rotation. A 47-year-old woman underwent left tertiary breast reconstruction with stacked free flaps using right deep inferior epigastric perforator and left SIEA vessels. Antegrade and retrograde anastomoses to the internal mammary (IM) vessels were preferred; additionally, the thoracodorsal vessels were unavailable due to previous latissimus dorsi breast reconstruction. Optimal shaping required repositioning of the lateral ends of the flaps superiorly, which would position the ipsilateral SIEA hemi-flap pedicle lateral to and out of reach of the IM vessels. This problem was overcome by turning the SIEA flap on its long axis, allowing the pedicle to sit medially with the lateral end of the flap positioned superiorly. The de-epithelialized SIEA flap dermis was in direct contact with the chest wall, enabling its fixation. This method of flap inset provides a valuable solution for medializing the SIEA pedicle while maintaining an aesthetically satisfactory orientation. This technique could be used in ipsilateral SIEA flap breast reconstructions that do not require a skin paddle, as with stacked flaps or following nipple-sparing mastectomy.

Multiple primary malignant neoplasms refer to two or more malignancies in an individual that are not related. We report a case of a 78-year-old male with concurrent breast mucinous carcinoma and extramammary lymphoma. The patient initially presented with palpable masses in the left breast and the right groin, which were pathologically confirmed after a surgical biopsy as breast mucinous carcinoma and diffuse large B-cell lymphoma, respectively. He underwent whole-body 18-fluorine deoxyglucose PET/CT before surgery, and an enhancing nodular lesion in the left lingual tonsil was found incidentally. It was later confirmed as a diffuse large B-cell lymphoma, a pathology of the same type as the right inguinal mass. Unspecified lymphadenopathies in breast cancer patients may easily be considered as metastatic lesions. However, this case suggests that lymphomas should be included in the differential diagnoses to avoid misdiagnosis and treatment delay, especially in older adult patients.

Among the treatment options for BRCA mutation carriers, risk reducing surgery is the most effective. However, this procedure has been rarely performed in Korea. Interestingly, our case showed double heterozygosity for BRCA1 and BRCA2 mutations. The patient was diagnosed with left renal cancer and left breast cancer at 45-years-of-age, 4 years before risk reducing surgery. The patient received left radical nephrectomy and left partial mastectomy with axillary lymph node dissection. After pretest counseling, the patient underwent genetic testing that identified BRCA1 and BRCA2 mutations. After post-test counseling, the patient decided on intensive surveillance. At 49-years-of-age, the patient was newly diagnosed with contralateral breast cancer. Treatment options were discussed once again. We performed bilateral total mastectomy with immediate reconstruction and prophylactic bilateral salpingo-oophorectomy after multidisciplinary discussion. The patient has been satisfied with the results of surgery. We think this procedure is a recommendable treatment option for BRCA mutation carriers.

Background: Radiotherapy is an important treatment of choice for breast cancer patients after breast-conserving surgery, and we compare the feasibility of using dual arc volumetric modulated arc therapy (VMAT2), single arc volumetric modulated arc therapy (VMAT1) and Multi-beam Intensity Modulated Radiotherapy (M-IMRT) on patients after breast-conserving surgery. Materials and Methods: Thirty patients with breast cancer (half right-sided and half left-sided) treated by conservative lumpectomy and requiring whole breast radiotherapy with tumor bed boost were planned with three different radiotherapy techniques: 1) VMAT1; 2) VMAT2; 3) M-IMRT. The distributions for the planning target volume (PTV) and organs at risk (OARs) were compared. Dosimetries for all the techniques were compared. Results: All three techniques satisfied the dose constraint well. VMAT2 showed no obvious difference in the homogeneity index (HI) and conformity index (CI) of the PTV with respect to M-IMRT and VMAT1. VMAT2 clearly improved the treatment efficiency and can also decrease the mean dose and V5Gy of the contralateral lung. The mean dose and maximum dose of the spinal cord and contralateral breast were lower for VMAT2 than the other two techniques. The very low dose distribution (V1Gy) of the contralateral breast also showed great reduction in VMAT2 compared with the other two techniques. For the ipsilateral lung of right-sided breast cancer, the mean dose was decreased significantly in VMAT2 compared with VMAT1 and M-IMRT. The V20Gy and V30Gy of the ipsilateral lung of the left-sided breast cancer for VMAT2 showed obvious reduction compared with the other two techniques. The heart statistics of VMAT2 also decreased considerably compared to VMAT1 and M-IMRT. Conclusions: Compared to the other two techniques, the dual arc volumetric modulated arc therapy technique reduced radiation dose exposure to the organs at risk and maintained a reasonable target dose distribution.

Central venous stenosis is a rare cause of unilateral breast edema occurring in hemodialysis patients that needs to be differentiated from other differential diagnoses, including, but not limited to, inflammatory breast carcinoma, mastitis, lymphedema, and congestive heart failure. All reports of similar cases in the available literature have described improvement or resolution of the edema after treatment. Herein, we report and discuss the pathophysiology of breast edema formation in a patient who presented with massive left-sided breast edema 7 years after being diagnosed with central venous stenosis. Medical and minimally invasive therapy had not been successful, so she underwent reduction mammoplasty to relieve the symptoms.

This report is aimed to investigate the effect of Traditional Korean Therapy (TKT) in treating recurred breast cancer metastasized to lung. A 53-year-old woman who was diagnosed as left breast cancer and underwent surgery, adjuvant chemotherapy and radiotherapy in early 2009 was admitted for the treatment of recurred, metastatic lung cancer in late 2012. She was treated with TKT including acupuncture, moxibustion and pharmacopuncture. The effect was evaluated with positron emission tomogram and computed tomogram (PET-CT). The metastatic tumors in both lungs were disappeared after the treatment for about 2 months. These results suggest that TKT is a therapeutic method to treat metastatic lung cancer originated from breast cancer.

Metastasis of rhabdomysarcoma to the breast is a very rare manifestation in adult males. Herein, we report a case of metastasis from embryonal rhabdomyosarcoma in the left hypothenar muscle that presented as a breast mass in a 38-year-old man, who four months later expired because of multiple bone metastases related to pancytopenia. We describe the various imaging findings, including mammograms, ultrasonography, computerized tomography (CT), positron emission tomography-computed tomography (PET-CT), and magnetic resonance imaging (MRI) of this rare disease. The various imaging findings of this lesion could be helpful for future diagnosis of male breast lesions.
