Breast augmentation mastopexy is a common procedure in cosmetic plastic surgery. Augmentation mastopexy has proven to be a relatively safe operation, but surgeons should be aware of and able to cope with disastrous complications such as soft tissue necrosis and nipple loss. The most important consideration in breast reconstruction is the recovery of breast shape and symmetry, as well as the maintenance of the shape of the nipple-areolar complex without any complications. We experienced a case of sequential breast and nipple-areolar complex reconstruction, in which the purse-string suture technique was used to repair medium-sized circular defects accompanied by nipple loss in the central area of both breasts and to preserve the shape of both breast mounds. Modified CV flaps were performed for left nipple reconstruction, and the Elsahy method and the purse-string suture technique were used to reconstruct the right nipple. Tattooing was performed on both breasts for areolar reconstruction. Through sequential reconstruction, the patient achieved satisfactory aesthetic results. In medium-sized, round defects on the central breast accompanied by nipple loss, the pursestring technique is a simple and effective reconstructive option that enables maintenance of the breast mound shape without requiring additional incision or distortion of surrounding structures.

Sebaceous carcinoma is a malignant neoplasm that usually arises in the sebaceous glands of the eyelids. Its pathogenesis is unknown; however, irradiation history, immunosuppression, and use of diuretics are known risk factors. The mainstay of treatment for sebaceous carcinoma of the eyelid is wide surgical resection with a safety margin of 5 to 6 mm, which often results in full-thickness defects. The reconstruction of a full-thickness defect of the eyelid should be approached using a three-lamella method: a mucosal component replacing the conjunctiva, a cartilage component for the tarsal plate, and a flap or skin graft for the skin of the eyelid. In this case, a fullthickness defect of the upper eyelid was reconstructed after tumor removal using a combination of a nasal septum chondromucosal composite graft and a forehead transposition flap, also known as a “Fricke flap.” The flap was designed to include a line of the eyebrow on the lower margin of the flap to replace the eyelash removed during tumor excision. The wound healed completely, without any early or late complications, and the outcome was satisfactory.

BACKGROUND: Folliculotropic mycosis fungoides (FMF) is a variant of mycosis fungoides (MF) that is characterized clinically by variable types of skin eruptions, including plaques, acneiform lesions, and alopecic patches. Histopathologically, FMF is characterized by folliculotropic infiltrates. OBJECTIVE: This study was conducted to scrutinize the clinical and histopathologic features of FMF in Koreans and the responses to phototherapy. METHODS: Twenty Koreans diagnosed with MF who had histopathologic evidence of folliculotropism were enrolled. RESULTS: Eighteen patients had head-and-neck-region infiltration, while five had solitary lesion. In all patients, the atypical lymphocytic infiltrate had a perifollicular distribution. Twelve patients were treated with ultraviolet A (UVA)-1. Eleven of these 12 patients with early-stage FMF experienced >80% improvement (8: complete remission; 3: partial remission). Four patients, including 2 who relapsed after UVA-1, were treated with photodynamic therapy (PDT), reaching complete remission after PDT. CONCLUSION: As FMF has variable clinical presentations, skin biopsy is required to confirm the diagnosis. And both UVA-1 and methyl aminolevulinate-PDT are clinically effective in treatment of early-stage FMF.

PURPOSE: To evaluate the diagnostic performance of three-dimensional fast spin-echo (3D FSE-Cube) without fat suppression (NFS) for detecting knee lesions, using comparison to 3D FSE-Cube with fat suppression (FS). MATERIALS AND METHODS: One hundred twenty-four patients who underwent 1.5T knee magnetic resonance imaging (MRI) scans and 25 subsequent arthroscopic surgeries were retrospectively reviewed. Using arthroscopic results and two-dimensional images as reference standards, diagnostic performances of 3D FSE-Cube-NFS and FS imaging about lesions of ligament, meniscus, subchondral bone marrow edema (BME), and cartilage were compared. Scan parameters of 3D FSE-Cube imaging were previously optimized by a porcine knee phantom. RESULTS: No significant differences were observed between detection rates of NFS and FS imaging for detecting lesions of meniscus and cartilage (p>0.05). However, NFS imaging had lower sensitivity for detection of medial collateral ligament (MCL) tears, and lower sensitivity and specificity for detection of BME lesions, compared to FS imaging (p<0.05). CONCLUSION: 3D FSE-Cube-NFS imaging showed similar diagnostic performance for detecting lesions of meniscus or cartilage compared to FS imaging, unlike MCL or BME lesions.

PURPOSE: To determine whether we should recommend ultrasonography (US) for an incidental thyroid nodule identified by additional cervicothoracic sagittal T2-weighted image (C-T sag T2WI) of lumbar spine magnetic resonance imaging (MRI). MATERIALS AND METHODS: A retrospective study of 61 patients who underwent both lumbar spine MRI and thyroid US between December 2011 and April 2015 was conducted. For all US-found thyroid nodules > 1 cm, investigators evaluated whether there was any correlation between thyroid nodule detectability by C-T sag T2WI and US features such as echogenicity, composition, or suspicion of malignancy. RESULTS: Solid hypoechoic (2/4; 50%) or mixed echoic nodules (4/8; 50%) appeared to be found relatively more easily by C-T sag T2WI than more benign-looking solid isoechoic (1/4; 25%) or spongiform nodules (0/6; 0%). Among six nodules with ultrasonographic suspicion for malignancy, only one nodule was detected by C-T sag T2WI. CONCLUSION: If an incidental thyroid nodule is seen by C-T sag T2WI, it would be better to recommend thyroid US for identifying malignancy.

The number of patients with chronic renal failure who require renal replacement therapy is increasing and dialysis is still the mainly used renal replacement therapy. The first choice of surgical technique currently used is side-to-end anastomosis of the radial artery and the cephalic vein. The authors report on a case of an effective arteriovenous shunt operation performed using microscopy. A 53-year-old male with chronic renal failure was referred to plastic and reconstructive surgery department to undergo an arteriovenous shunt operation. Venography was performed before surgery in order to find the appropriate vessel for the arteriovenous shunt operation. The cephalic vein on the wrist showed a diameter of over 4 mm, which was appropriate for an arteriovenous shunt operation. Anastomosis of the vessels was performed under microscopy using Nylon #9-0. Blood flow and vessel diameter were evaluated by venography after surgery and showed well maintained function of the shunt. Complications such as bleeding, edema of the upper arm, and wound dehiscence did not occur. Many factors and certain complications may affect the long-term patency of an arteriovenous shunt; however, exquisite surgical technique is the most important factor in a successful operation. Thus, arteriovenous shunt operation using microscopy is thought to be a good treatment option.

PURPOSE: The purpose of this study was to find and categorize the various magnetic resonance imaging (MRI) findings of spinal metastases that correlate with the type of primary cancer. MATERIALS AND METHODS: We retrospectively reviewed gadolinium-enhanced magnetic resonance images of 30 patients with 169 spinal metastatic lesions from lung cancer (n = 56), breast cancer (n = 29), colorectal cancer (n = 20), hepatocellular carcinoma (HCC) (n = 17), and stomach cancer (n = 47). The size, location, extent of invasion, signal intensity, margin, enhancement pattern, and osteoblastic or osteolytic characteristics of each metastatic tumor were analyzed. RESULTS: The metastatic lesions from HCC were larger than those from the other primary tumors (P < 0.05) except for colorectal cancer (P = 0.268). Well-defined metastatic tumor margins were more frequently seen in lung cancer and breast cancer (P < 0.01). All but HCC showed a tendency to invade the vertebral body rather than the posterior elements (P < 0.02). Colorectal cancer and HCC showed a tendency toward extraosseous invasion without statistical significance. HCC showed a characteristic enhancement pattern of 'worms-in-a-bag'. Rim enhancement with a sclerotic center was only seen in spinal metastases from stomach cancer. CONCLUSION: Despite many overlapping imaging features, spinal metastases of various primary tumors display some characteristic MRI findings that can help identify the primary cancer.

PURPOSE: To validate the feasibility of real time kinematography with four-dimensional (4D) dynamic functional wrist joint imaging using dual source CT. MATERIALS AND METHODS: Two healthy volunteers performed radioulnar deviation and pronation-supination wrist motions for 10 s and 4 s per cycle in a dual source CT scanner. Scan and reconstruction protocols were set to optimize temporal resolution. Cine images of the reconstructed carpal bone of the moving wrist were recorded. The quality of the images and radiation dosage were evaluated. RESULTS: The 4D cine images obtained during 4 s and 10 s of radioulnar motion showed a smooth stream of movement with good quality and little noise or artifact. Images from the pronation-supination motion showed noise with a masked surface contour. The temporal resolution was optimized at 0.28 s. CONCLUSION: Using dual source CT, 4D cine images of in vivo kinematics of wrist joint movement were obtained and found to have a shorter scan time, improved temporal resolution and lower radiation dosages compared with those previously reported.
