BACKGROUND: The goal of this study was to investigate the anatomy of the peroneal artery and its perforators, and to report the clinical results of reconstruction with peroneal artery perforator flaps. METHODS: The authors dissected 4 cadaver legs and investigated the distribution, course, origin, number, type, and length of the perforators. Peroneal artery perforator flap surgery was performed on 29 patients. RESULTS: We identified 19 perforators in 4 legs. The mean number of perforators was 4.8 per leg, and the mean length was 4.8 cm. Five perforators were found proximally, 9 medially, and 5 distally. We found 12 true septocutaneous perforators and 7 musculocutaneous perforators. Four emerged from the posterior tibia artery, and 15 were from the peroneal artery. The peroneal artery perforator flap was used in 29 patients. Retrograde island peroneal flaps were used in 8 cases, anterograde island peroneal flaps in 5 cases, and free peroneal flaps in 16 cases. The mean age was 59.9 years, and the defect size ranged from 2.0 cm×4.5 cm to 8.0 cm×8.0 cm. All the flaps survived. Five flaps developed partial skin necrosis. In 2 cases, a split-thickness skin graft was performed, and the other 3 cases were treated without any additional procedures. CONCLUSIONS: The peroneal artery perforator flap is a good alternative for the reconstruction of soft tissue defects, with a constant and reliable vascular pedicle, thin and pliable skin, and the possibility of creating a composite tissue flap.

2.Absence of Linea Alba in Breast Reconstruction with Pedicled TRAM Flap: A Case Report.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2011;38(3):326-328
PURPOSE: The anatomical anomaly of the rectus abdominis muscle and it's fascia is very rare. No case of the absence of the linea alba below the umbilicus has yet been reported. During breast reconstruction with pedicled TRAM flap, we experienced one case of absence of linea alba. METHODS: The patient was a 38-years old female who underwent immediate breast reconstruction with pedicled TRAM flap after Right modified radical mastectomy in June 2010. While the TRAM flap was being elevated, bilateral twitching of the rectus abdominis muscle occurred when electrocautery was applied, and we found the absence of the linea alba below the umbilicus. RESULTS: When the rectus abdominis muscle was exposed, the linea alba below the umbilicus was not observed, and the bilateral rectus abdominis muscle was indistinguishably fused in a gross observation. In addition, bilateral twitching of rectus abdominis muscle was simultaneously observed as one muscle unit when electrocautery was applied. As with both rectus abdominis muscles was bluntly dissected with scissors, the scanty fatty tissues were observed between the both rectus muscles, and the bilateral rectus abdominis muscle was easily separated. The flap was transposed into the corresponding defect to make breast mound. Midline fascia was fixed to the posterior rectus sheath to reconstruct smilar anatomic linea alba. Abdominal defect was reinforced by suturing between remaining anterior rectus sheath. CONCLUSION: As the unexpected anatomical anomaly may affect the operation outcome, surgeons should be careful when they unexpectedly encounter the anatomical anomaly during an operation. Here, we report a rare case of absence of the linea alba seen at the time of pedicled TRAM flap elevation for breast reconstruction.

Recently, rejuvenation of the aging hand has gained popularity. Various medical fillers have recently become popular, and patients have more options to rejuvenate their aging hands. However, in our country, unregulated material injections by unlicensed practitioners are still wide spread and its related complications have been considered as a serious problem. The aim of this retrospective study is to introduce our experiences regarding 17 cases of foreign body granuloma following hand rejuvenation using unregulated material. A retrospective review from December 2002 to October 2012 was performed. We analyzed data for 17 patients who underwent perilesional surgical excision for treatment of a foreign body granuloma of the hand associated with unregulated material injection by unlicensed practitioners. Injected materials include paraffin, silicone oil, and other unknown materials. Four patients were injected with paraffin, 3 patients with silicone oil, and remaining 10 patients with unknown materials. The main symptom was palpable mass and contour deformity. The patients were asked to rate their overall satisfaction following treatment. The average patient satisfaction score was 3.7. To prevent foreign body granuloma following unregulated medical practice, it is very important to inform the public about the disastrous consequence of unregulated material injections by unlicensed practitioners.

We experienced an unusual case of the cellular nevus on the dorsal surface of the second metacarpophalangeal joint. We performed a local excision followed by immunohistochemical analysis. Cellular blue nevus should be considered in the differential diagnosis when a characteristic blue-black mass is found in the finger. Accurate diagnosis based on immunohistochemical analysis, appropriate surgical treatment and vigilant follow-up are mandatory to prevent any malignant transformation.

PURPOSE: Dermatofibroma is a common benign dermal tumor characterized by a proliferation of fibroblast-like spindle cells. It is commonly localized on the skin of extremities and presents as a slow growing solitary nodule. To our knowledge, the occurrence of dermatofibroma in the oral cavity is rare. Herein, we report a rare case of dermatofibroma on the lower lip. METHODS: A 60-year-old woman presented with a slow growing mass that measured 1 x 0.8 cm in diameter on the lower lip. The mass was surgically excised with clear margins. RESULTS: Histologically, the mass was characterized by a nodular tumor composed of collagen bundles, fibroblasts, and histiocytes, which were findings consistent with dermatofibroma. The postoperative course was uneventful without any complications. CONCLUSION: When evaluating nodular tumors of the oral area, dermatofibroma should be considered in the differential diagnosis.

OBJECTIVE: The aim of the present study was to investigate the clinical usefulness of serum CA 125 and CA 19-9 levels for diagnosing and determining the severity of endometriosis. METHODS: A total of 112 women who underwent gynecologic surgery between January 1998 and August 2004 were selected in this study. 81 patients had histologically confirmed endometriosis and the remaining 31 had benign ovarian tumor but no obvious evidence of endometriosis. Blood samples were collected in all patients before the operation and the mean values and standard deviations of both serum CA 125 and CA 19-9 levels were measured in various stages of disease. Both tumor markers were also measured in the control group. The results were compared to determine the usefulness of CA 125 and CA 19-9 in diagnosing and predicting the severity of endometriosis. As a results, new cutoff values of serum CA 125 and CA 19-9 in endometriosis were obtained. RESULTS: The mean levels of serum CA 125 and CA 19-9 in patients at stage III and IV of endometriosis were significantly higher than in patients without endometriosis, and increased in accordance with the advancement of the clinical stage. Statistically appropriate cutoff values of CA 125 and CA 19-9 were calculated to be 20 IU/mL and 10 IU/mL, respectively. The sensitivity and specificity of CA 125 at this cutoff value for endometriosis were 72% and 71%, respectively. The sensitivity and specificity were 59% and 55% respectively in the case of CA 19-9. CONCLUSION: CA 125 is a useful marker for diagnosing and determining the severity of endometriosis. CA 19-9 shows limitation in diagnosing endometriosis, but is indeed a potential marker in predicting the severity of disease.

Scar revision techniques are chief among the most important skills for facial plastic and reconstructive surgeons. In order to achieve the least amount of scarring following a surgical procedure, it is crucial that the surgeon always consider skin tension. In our hospital, staged scar revision was conducted on patients with angulated facial scars in order to reduce skin tension. We conducted a retrospective chart review of patients undergoing staged scar revision for angulated facial scars at our hospital from July 2002 to September 2010. The follow-up period was at least six months. All pre-and post-operative photographs were analyzed by two independent plastic surgeons. And the patients were asked to rate their overall satisfaction with their scar revision as very satisfied(5), satisfied(4), neutral(3), dissatisfied(2) or completely dissatisfied(1). Staged scar revision was used in 51 patients with angulated facial scars. Overall, a significantly improved scar and above(score > or =4), graded by an independent plastic surgerns, was notes in 47 patients(92.1%). And, 45 patients(88.2%) were satisfied with their scar revisions. In all cases, the postoperative clinical course was uneventful without any complications. In conclusion, staged scar revision is considered a good option for the treatment of angulated facial scar.

Spontaneous intra-abdominal hemorrhage from uterine leiomyomas is rarely encountered. We present a case of a 46-year-old who presented to the emergency room with acute abdominal pain as same as that has experienced for 5-6 times. On examination, the abdomen was diffusely tender, with rebound tenderness in the suprapubic area and in both iliac fossae. Pregnancy test was negative. She had an acute abdomen, dizziness, decreasing hematocrit, and a pelvic mass with free fluid in the pelvic cavity. On transvaginal sonography, 6.3 x 6.1 cm sized hyperechoic mass was visible beside the uterus and CDS. This mass had an ill-defined margin. Large amount of fluid was visible in the CDS and uterovesical pouch. Hemoperitoneum was confirmed by culdocentesis. Magnetic Resonance Imaging revealed a mass with cystic components, diffusely heterogeneous signal intensity and T1 high signal intensity in the left superolateral aspect of uterus. An moderate amount of fluid was found in the pelvic cavity. The patient underwent an exploratory laparotomy. A ruptured, pedunculated, cystic degenerated uterine myoma with active bleeding was found, as well as approximately a liter of free, blood-stained peritoneal fluid and blood-clots. Myomectomy was performed, followed by evacuation of the fluid and clots. The patient's postoperative course was uneventful. In conclusion, preoperative diagnosis of a perforated, uterine fibroid with spontaneous intra-abdominal hemorrhage is difficult; exploratory laparotomy is both diagnostic and therapeutic in this rare, life-threatening condition.

Agenesis of corpus callosum is the cerebral malformations whose prognosis is uncertain. But the complete agenesis shows more poor prognosis than partial agenesis. So, the type of agenesis can affect significantly the antepartum management. Recently, there has been a development in diagnostic tools like MRI to overcome these limitations of antenatal ultrasonography. We report a case of agenesis of corpus callosum which was diagnosed by prenatal MRI. This case was confused with Dandy-Walker complex in prenatal ultrasonography and supported in diagnosis by prental MRI.
