RESUMEN
A 46-year-old woman demonstrated refractory Kounis syndrome (KS) after induction of anesthesia. Despite conventional management of anaphylaxis and advanced cardiac life support, her cardiovascular function continued to deteriorate until she had a cardiac arrest, and after extracorporeal membrane oxygenation (ECMO) therapy, electrical cardiac activity reappeared. A large number of patients with KS-"allergic angina syndrome"-has been known to recover well with vasodilators; however, this patient showed antibiotics-induced refractory KS during general anesthesia. Severe bronchospasms with desaturation appeared as initial anaphylactic features; however, these did not respond to conventional treatment for anaphylaxis. Patient's hemodynamic signs eventually worsened, leading to cardiac arrest despite ephedrine administration and chest compressions. During cardiopulmonary cerebral resuscitation, the central line was secured, and epinephrine, atropine, as well as sodium bicarbonate were administered repeatedly; nevertheless, cardiac arrest was sustained. After initiation of veno-arterial ECMO, atrial fibrillation was observed, which was later converted to sinus tachycardia by electrical cardioversions and amiodarone. Coronary angiography was performed before the patient was admitted to the intensive care unit; there were no indications of an impending cardiac arrest. The patient was discharged uneventfully owing to early use of ECMO despite the emergence of KS symptoms that were initially masked by anesthesia but later worsened abruptly.

BACKGROUND: Laparoscopic primary repair is one of the main procedures used for perforated gastric ulcers, and this technique requires reproducible and secure suturing. The aim of this study was to investigate the safety and efficacy of a novel continuous suture method with barbed sutures during laparoscopic repair for perforated peptic ulcers. PATIENTS AND METHODS: Clinical data from 116 consecutive patients undergoing laparoscopic repair for perforated peptic ulcers were collected between November 2009 and October 2015. Continuous suturing with 15-cm-long unidirectional absorbable barbed sutures was used for laparoscopic repair in the study group, termed group V (n = 51). Patients who underwent laparoscopic repair with conventional interrupted sutures were defined as group C (n = 65). The complication and operative data were compared between groups. RESULTS: Although there was no difference between group V and group C in the overall complication rate (15.7% vs. 24.6%; p = 0.259), the complication rate related to suturing was lower (3.9% vs. 15.4%; p = 0.04) in group V. Group V showed rates of 0% for leakage, 2% for intra-abdominal fluid collection, and 2% for stricture; the corresponding rates in group C were 3.1, 7.7, and 4.6%, respectively. Regarding operative data, the total operation time (V vs. C, 87.7 min vs. 131.2 min), total suture time (7.1 min vs. 25.3 min), and suture time per stitch (1.2 min vs. 6.2 min) were significantly shorter in group V than in group C (p < 0.001). CONCLUSION: The use of a continuous suture technique with unidirectional barbed sutures is as safe as the conventional suture technique and allows easier and faster suturing in the repair of perforated peptic ulcers.

BACKGROUND: Because of the limitations in ultrasonography (US), the advantages of computed tomography (CT) for detecting central lymph node (LN) metastasis have been suggested in papillary thyroid carcinoma (PTC). METHODS: First, we compared the diagnostic accuracy of US and CT for detecting central LN metastasis in 6577 central neck levels from 3668 PTC patients. Second, to examine the clinical impact of CT-detected central LN metastasis (CT cN1a) in PTC patients with clinically node negative in US (US cN0), we selected two groups: group I comprised 1245 US cN0 PTC patients who did not have CT scans and did not undergo central neck dissection (CND), while group II comprised 348 US cN0 and CT cN1a PTC patients who underwent CND. After propensity score matching, 254 matched pairs were yielded. RESULTS: For detecting central LN metastasis, CT showed significantly higher sensitivity (38.9 vs. 27.5 %; p < 0.001) and accuracy (66.1 vs. 63.2 %; p < 0.001) than US. Furthermore, US + CT showed significantly higher sensitivity (47.8 vs. 27.5 %; p < 0.001) and accuracy (69.0 vs. 63.2 %; p < 0.001) than US. After matching, radioactive iodine ablation (81.5 vs. 85.8 %; p = 0.235) and locoregional recurrence (p = 0.663) were not significantly different between groups I and II. CONCLUSIONS: Despite the diagnostic advantages of preoperative CT, 'CT-based CND' in US cN0 PTC patients did not significantly influence postoperative management and locoregional recurrence. The strategy for the management of central neck in PTC patients can be sufficiently determined by US only.

BACKGROUND: There was a difficulty for detecting Central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) patients. Therefore, the purpose of this study was to design a nomogram for predicting CLNM. METHODS: A total of 10,763 PTC patients who underwent total thyroidectomy with central neck dissection (CND) in Samsung Medical Center were randomly assigned to the training set (n = 7,535) and to the internal validation set (n = 3,228). And, a total of 2,514 PTC patients who underwent total thyroidectomy with CND at Seoul National University Hospital were assigned to the external validation set. RESULTS: The values of the area under the receiver operating characteristic curve in the training set, internal validation set, and external validation set were 0.721 (95% confidence interval [CI], 0.709-0.732), 0.706 (95%CI, 0.688-0.724), and 0.706 (95%CI, 0.685-0.727), respectively. CONCLUSIONS: We recommend the use of our nomogram to enable clinicians and patients to easily personalize and quantify the probability of CLNM during the both pre- and postoperative period. Clinicians may consider the prophylactic CND and meticulous postoperative evaluation in PTC patients with a high nomogram score. J. Surg. Oncol. 2017;115:266-272. © 2016 Wiley Periodicals, Inc.

INTRODUCTION: Bilateral axillo-breast approach (BABA) robotic thyroidectomy (RT) is proven to be a feasible method for the treatment of well-differentiated thyroid cancers in terms of oncology as well as cosmesis. However, BABA RT causes postoperative sternal discomfort and needs an incision over the nipple areolar area. Here, we suggest a novel robotic surgical technique for thyroid surgery that does not need a breast incision-bilateral axillary approach (BAA). PATIENTS AND METHODS: We recruited 51 patients who were willing to undergo the novel BAA robotic thyroid surgery. We performed a propensity score-matched analysis to compare the BAA robotic thyroid surgery group (BAA group) with the conventional open thyroid surgery group (open group). RESULTS: Mean operation time in the BAA group (129.7 min) was significantly longer than that in the open group (103.1 min) (p < 0.001). However, no significant differences in the mean number of metastatic lymph nodes (LNs), mean number of retrieved LNs, vocal cord palsy, hypoparathyroidism, and mean stimulated thyroglobulin level were observed between the two groups. There was no case of postoperative bleeding or chyle leak. Of the 51 patients who had undergone the BAA procedure, 27 patients answered the questionnaire. The mean scale, ranging from 0 to 10, at postoperative 1 day/2 weeks was as follows: voice change score, 3.0/1.6; swallowing difficulty score, 4.0/2.0; anterior neck pain score, 4.6/3.6; anterior neck numbness score, 5.4/4.3; right chest pain score, 3.8/2.1; left chest pain score, 3.6/2.3; right chest numbness score, 3.2/2.8; left chest numbness score, 2.4/2.7; right breast pain score, 0.9/0; left breast pain score, 1.2/0; right breast numbness score, 1.7/0; and left breast numbness score, 2.6/0, respectively. CONCLUSION: BAA robotic thyroid surgery is a novel, safe, and feasible oncoplastic method, especially for patients who have fear of procedures around the nipple areolar complex.

BACKGROUND: The safety of robotic thyroidectomy (RT) for small-sized thyroid carcinomas has been well established. The surgical outcomes of bilateral axillo-breast approach RT for thyroid carcinomas larger than 2 cm were evaluated and compared with those of open thyroidectomy (OT). METHODS: The medical records of patients who underwent total thyroidectomy or hemithyroidectomy followed by completion thyroidectomy for differentiated thyroid carcinomas measuring 2-4 cm were retrospectively reviewed. RESULTS: The study included 86 patients who underwent RT (n = 21) or OT (n = 65) with mean ages of 30.8 and 51.6 years, respectively. The mean tumor size was 2.8 cm in both groups. There were no significant differences between the RT and OT groups in vocal cord palsy rate (transient, 19.0 vs. 9.2 %; permanent, 0 vs. 1.5 %), postoperative hypoparathyroidism rate (transient, 19.0 vs. 33.8 %; permanent, 4.8 vs. 1.5 %), and the number of retrieved central lymph nodes in papillary thyroid carcinoma patients (6.4 ± 3.5 vs. 6.1 ± 3.9, respectively). The proportion of the patients with serum stimulated thyroglobulin level of <1.0 ng/ml at the initial radioactive iodine treatment was 64.7 % (11/17) for RT group and 66.0 % (35/53) for OT group (p = 0.920). There were three patients (1 RT and 2 OT) who had a biochemical incomplete response, and there was no case of anatomical recurrence or mortality during the median follow-up period of 40.2 months. CONCLUSION: RT is a safe and oncologically sound treatment option for differentiated thyroid carcinomas measuring 2-4 cm in a selected group of patients. The role of RT should be evaluated in correlation with technological advances and increased experience.

PURPOSE: The da Vinci surgical robot system was developed to overcome the weaknesses of endoscopic surgery. However, whether robotic surgery is superior to endoscopic surgery remains uncertain. Therefore, the purpose of this study was to compare the surgical and oncologic outcomes between endoscopic and robotic thyroidectomy using bilateral axillo-breast approach (BABA). METHODS: Between January 2008 and June 2015, papillary thyroid carcinoma patients who underwent thyroidectomy with central neck dissection using endoscopic (n = 480) or robotic (n = 705) BABA were primarily reviewed. We performed 1:1 propensity score matching and 289 matched pairs were yielded. RESULTS: Operation time was significantly longer in the robotic thyroidectomy than in the endoscopic thyroidectomy (184.9 vs. 128.9 min, P < 0.001). A significantly higher number of central lymph nodes (CLNs) were resected in the robotic thyroidectomy than in the endoscopic thyroidectomy (5.3 vs. 4.4, P = 0.003). However, the incidence of other outcomes including hospital stay, postoperative duration, thyroglobulin level, radioactive iodine ablation, hemorrhage, chyle leakage, wound infection, recurrent laryngeal nerve injury, and loco-regional recurrence did not significantly differ between the endoscopic thyroidectomy and the robotic thyroidectomy. CONCLUSIONS: Endoscopic thyroidectomy is comparable with robotic thyroidectomy in view of surgical complications and LRR. Because robotic thyroidectomy resected a larger number of CLNs than did endoscopic thyroidectomy, further long-term follow-up studies will be required to clarify the possible prognostic benefits of robotic thyroidectomy.

BACKGROUND: Because lymph node (LN) metastasis has been proven to be a predictor for locoregional recurrence (LRR) in papillary thyroid microcarcinoma (PTMC), better knowledge about the predictors for LN metastasis in PTMC is required. METHODS: We retrospectively reviewed 5656 PTMC patients who underwent total thyroidectomy and central neck dissection and/or lateral neck dissection between January 1997 and June 2015. RESULTS: Male gender (adjusted odds ratio [OR] 2.332), conventional variant (adjusted OR 4.266), tumor size >0.5 cm (adjusted OR 1.753), multiplicity (adjusted OR 1.168), bilaterality (adjusted OR 1.177), and extrathyroidal extension (ETE) (adjusted OR 1.448) were independent predictors for high prevalence of central LN metastasis (CLNM), whereas per 10-year age increment (adjusted OR 0.760) and chronic lymphocytic thyroiditis (adjusted OR 0.791) were independent predictors for low prevalence of CLNM. In addition, male gender (adjusted OR 1.489), tumor size >0.5 cm (adjusted OR 1.295), multiplicity (adjusted OR 1.801), ETE (adjusted OR 1.659), and CLNM (adjusted OR 4.359) were independent predictors for high prevalence of lateral LN metastasis (LLNM), whereas per 10-year age increment (adjusted OR 0.838) was an independent predictor for low prevalence of LLNM. There was a statistically significant difference in LRR with regard to nodal stage (p < 0.001). CONCLUSIONS: Meticulous perioperative evaluation of LN metastasis is required for PTMC patients with the above predictors.

BACKGROUND: The failure to preserve parathyroid function in patients who have undergone total thyroidectomy is of major concern, because hypocalcemia is difficult to prevent and remains a common postoperative complication. Here, we describe procedures designed to preserve the vasculature supplying the parathyroid glands and examine both recent outcomes and retrospective reports of results obtained prior to the application of these preservation techniques. METHODS: Our technique for preserving parathyroid function during thyroidectomy was adopted in 2009 and involves separating a relatively long segment of a vessel distally from the thyroid gland. We reviewed the medical records of 1,411 patients who underwent total thyroidectomy, with or without lateral neck dissection, at the Samsung Medical Center from January 2006 through June 2014 to determine outcomes. Patients were divided into three groups according to the time period during which the surgery took place: Group A, 2006-2008 (before the vasculature-preserving technique was applied); Group B, 2009-2011 (the time when the technique was first adopted); and Group C, 2012-2014 (more recent results of the technique). We analyzed the incidence of hypoparathyroidism in the three groups, as well as risk factors that influenced its development. RESULTS: The rates of transient and permanent hypoparathyroidism in Group A were 25.4 and 4.3 %, respectively. However, the incidence of hypoparathyroidism decreased significantly over time after the vasculature-preserving procedure was adopted. Transient hypoparathyroidism developed in 4.8 % of Group C patients, and only four (0.7 %) of the 565 patients in this group required calcium supplementation, despite the fact that a greater number of patients were included who underwent total thyroidectomy combined with lateral neck dissection. Although female sex and lateral neck dissection tended to increase the rate of transient hypoparathyroidism, multivariate analysis showed that the vasculature-preserving procedure was the only significant risk factor related to postoperative hypoparathyroidism. CONCLUSION: The blood flow of the final branch to the parathyroid gland is mostly in the lateral-to-medial direction; therefore, mobilization and preservation of the vessels lateral to the gland is essential to prevent devascularization of the parathyroid gland.

To assess vocal cord (VC) movement with transcutaneous laryngeal ultrasound (TLUSG), three maneuvers, namely passive (quiet respiration), active (phonation), and Valsalva maneuvers have been described. It remains unclear which maneuver or using more maneuvers provides better visualization and assessment accuracy. We prospectively evaluated 342 post-thyroidectomy patients from two centers. They underwent TLUSG with direct laryngoscopic (DL) validation afterwards. During TLUSG, patients were instructed to perform all three maneuvers (passive, active, and Valsalva). VC visualization rate and accuracy between three maneuvers were compared. Visualization rate tended to be higher in Valsalva maneuver than that in other two maneuvers (92.1% vs. passive: 91.5%; active: 89.8%). While 19 patients had post-operative VC palsy, passive maneuver had lower test specificity than active (94.3 vs. 97.6%, p = 0.01) and Valsalva maneuvers (94.3 vs. 97.4%, p = 0.02). In assessable VCs, passive maneuver has a higher ability to differentiate between mobile VCs and VC palsy (Area under ROC curve--passive: 0.942, active: 0.863, Valsalva: 0.893). TLUSG with more maneuvers did not improve sensitivity or specificity. On applying TLUSG as a screening tool (i.e., only selected patient with "unassessable" VCs or VCP on TLUSG for DL), Valsalva maneuver (85.96%) saved more patients from DL than passive (81.87%) or active (84.81%) maneuver. Passive maneuver has a higher ability to differentiate VC palsy from normal. Using TLUSG as a screening tool, Valsalva was the preferred maneuver as it was more specific, had high visualization rate, and saved more patients from DL.

BACKGROUND: Surgical procedures involving the thyroid gland require identification of the parathyroid glands. Indocyanine green (ICG) is a near-infrared (NIR) fluorescent contrast agent used for a variety of procedures such as intraoperative angiography, extrahepatic cholangiography, and lymph node mapping. In this study, we used a canine model to evaluate ICG for NIR fluorescent imaging of the parathyroid gland. METHODS: Three dogs were used for the study. The dogs were administered general anesthesia, and after surgical dissection, each dog received a series of intravenous ICG doses ranging from 12.5 to 100 µg/kg ICG. The excitation light source used to illuminate the operating field was a NIR laser (λ = 785 nm). Intravascular ICG fluorescence (λ = 835/45 nm) was recorded using a charge-coupled device that employed optical filtering to block ambient and laser light. Fluorescent imaging was assessed after injection of each dose of ICG. RESULTS: NIR fluorescent imaging visualized the parathyroid glands. The intensity curves showing the peak and plateau of fluorescence are similar regardless of the concentration of ICG. The time to peak fluorescent intensity was 50.2 ± 2.0 s after injection of ICG. Taking into consideration background fluorescent intensity, the estimated optimal dose of ICG was 18.75 µg/kg. At 106.7 ± 5.8 s, the parathyroid glands lost much of their fluorescence, although they remained sufficiently fluorescent to be distinguishable. There was a positive correlation of fluorescent intensity with ICG dose escalation up to 25 µg/kg. CONCLUSIONS: ICG NIR fluorescent imaging was useful in detecting the parathyroid glands of dogs. By allowing detection of parathyroid glands, the current technique shows promise for use by endocrine surgeons performing thyroidectomies.

BACKGROUND: The prognosis of patients with positive surgical resection margins is dismal in gastric cancer. However, the influence of positive margin itself on prognosis is still uncertain, especially in advanced gastric cancer (AGC). The aims of the present study were to evaluate the prognostic impact of microscopic tumor involved resection margins in stage III-IV AGC after gastric resection in comparison with other well-known factors. METHODS: Among 1,536 consecutive gastric cancer patients who received intentional curative resection for stage III-IV AGC between April 2001 and December 2011 at the National Cancer Center, 35 patients (2.28 %) had positive resection margins on their final histology. A comparison of clinicopathologic characteristics, recurrence pattern, overall survival (OS), and disease-free survival (DFS) was made between positive margin (PM) patients and negative margin (NM) patients. RESULTS: Among the 35 PM patients, 15 (42.9 %) had proximal involved margins, 21 (60.0 %) had distal involved margins, and one (2.9 %) had both involved margins. Twenty-eight PM patients (80.0 %) were stage III, and 7 (20.0 %) were stage IV. Recurrence was significantly higher in PM than NM (63.6 % vs. 39.7 %, respectively; p = 0.005). The OS and DFS rates were significantly lower in the PM group than in the NM group (14.9 vs. 36.3 months, p < 0.001 and 11.6 vs. 27.1 months, p = 0.005, respectively). The presence of PM was an independent risk factor for both OS and DFS. CONCLUSIONS: The presence of PM is an independent risk factor for OS and DFS. Considering the prognostic impact of PM, a sufficient resection margin should be ensured when determining the resection line in gastrectomy with curative intent. The reoperation to secure clear resection margins should be considered as a treatment of choice in the case of PM.

BACKGROUND: This study compared the surgical outcomes of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and transoral robotic thyroidectomy (TORT) in papillary thyroid cancer (PTC). METHODS: The TOETVA and TORT groups comprised 119 and 121 patients between November 2016 and May 2022. Clinico-surgical outcomes and operation times were retrospectively reviewed. RESULTS: The TORT group showed a higher number of retrieved central compartment lymph nodes, shorter hospital stays, and lower pain score after 48 h than the TOETVA group. No significant difference was observed in the other postoperative complications, including permanent vocal cord palsy. Total operation, working space creation, and endoscopic or robotic surgery times of the TORT group were longer than those of the TOETVA group. CONCLUSIONS: TORT and TOETVA are feasible and safe. TORT may have some advantages, such as central compartment node dissection, shorter hospital stays, and pain score after 48 h in PTC, despite a longer operative time.

OBJECTIVE: To compare clinical and operative results between laparoscopic primary repair (LPR) alone and LPR with highly selective vagotomy (LPR-HSV) in patients with duodenal ulcer perforation. METHODS: Clinical data from patients who underwent either LPR or LPR-HSV by resecting both sides of the neurovascular bundle using an ultrasonic or bipolar electrosurgical device for duodenal ulcer perforations, between 2010 and 2020, were retrospectively collected. Between-group differences in continuous and categorical variables were statistically analysed. RESULTS: Data from 184 patients (mean age, 49.6 years), who underwent either LPR (n = 132) or LPR-HSV (n = 52) were included. The mean operation time was significantly longer in the LPR-HSV group (116.5 ± 39.8 min) than in the LPR group (91.2 ± 33.3 min). Hospital stay was significantly shorter in the LPR-HSV group (8.6 ± 2.6 days) versus the LPR group (11.3 ± 7.1 days). The mean postoperative day of starting soft fluid diet was also significantly shorter in the LPR-HSV group (4.5 ± 1.4 days) than in the LPR group (5.6 ± 4 days). No between-group difference in morbidity rate was observed. The learning curve of the HSV procedure showed a stable procedure time after 10 operations. CONCLUSIONS: LPR with HSV may be a safe and feasible procedure for selective cases who are at high risk for ulcer recurrence.

Although BCL2 has occasionally been suggested as a candidate prognostic factor for breast cancer, it is still not accepted as a prognostic factor. We attempted to validate the role of BCL2 as a prognostic factor of breast cancer. Data on 7,230 primary breast cancer patients from the Seoul National University Hospital Breast Care Center were analyzed. Three current prognostic models, including the St. Gallen model, the Nottingham prognostic index (NPI) model and the TNM model, were used for analysis of the prognostic influence of BCL2. The positive BCL2 group showed more favorable features with regard to clinicopathologic parameters than the BCL2 negative group and a strong correlation was observed between BCL2 and the hormonal receptor. The positive BCL2 group showed better prognosis in overall survival and disease free survival (log-rank test, both p < 0.001), even in all subgroups, than the BCL2 negative group. BCL2 was a significant prognostic factor in both univariate (hazard ratio [HR], 0.361; 95% confidence interval (CI), 0.306-0.426; p < 0.001) and multivariate analyses (HR, 0.417; 95% CI, 0.417-0.705; p < 0.001). BCL2 had a strong influence on the established prognostic models, including the St. Gallen model, the NPI model and the TNM model. BCL2 was a powerful independent prognostic factor for breast cancer and had a strong influence on the current prognostic models. Favorable clinicopathologic features and a strong correlation with the hormonal receptor are suggested as the causes of superior survival in patients with BCL2 positive breast cancer.

Background: To date, red blood cell distribution width (RDW) and RDW-to-platelet count ratio (RPR) have been investigated for their association with cancer. This study aimed to investigate the prognostic value of RDW and RPR in breast cancer before and after treatment. Methods: We retrospectively enrolled 395 patients with breast cancer, who were diagnosed between December 2009 and December 2015 and analyzed the association between RDW, RPR, and long-term prognosis. We also compared the RDW and RPR values with the pathologic parameters of breast cancer. The cutoff values for before-treatment RDW, RPR value, after-treatment RDW, and RPR were determined using receiver operating characteristic (ROC) curve analysis by identifying the highest Youden index. Results: In the before-treatment state, no significant disease-free survival (DFS) or overall survival (OS) was found in the RPR and RDW values. However, we found that elevated after-treatment RPR and RDW were significant prognostic factors for DFS, with hazard ratios (HRs) of 2.233 [95% confidence interval (CI): 1.073-4.649; P=0.032] and 2.067 (95% CI: 1.085-3.937; P=0.027). Kaplan-Meier analysis indicated that the after-treatment RPR and RDW groups had poor OS (HR =30.461; 95% CI: 5.138-180.575; P<0.001) compared with the lower after-treatment RPR and RDW groups. In particular, when the RPR and RDW were in the lower group before the treatment and became elevated after the treatment, it showed a remarkably significant result for OS, with HR 132.6 (95% CI: 3.689-4,767.341; P=0.007) and 10.119 (95% CI: 1.853-55.249; P=0.008). Conclusions: Thus, after-treatment RPR and RDW could have prognostic value for breast cancer after surgery and adjuvant treatment.
RESUMEN
RATIONALE: Schwannoma in the breast parenchyma is very unusual. It usually develops on the head, neck, and extensor surfaces of the upper and lower extremities. PATIENT CONCERNS: We report a case of a 60-year-old woman with a palpable and painful mass. Clinically, she experienced neuropathic pain at the mass site. DIAGNOSES: The tumor was a 1âcm, well-circumscribed mass, and revealed schwannoma on core needle biopsy. INTERVENTIONS: The patient underwent wide excision. OUTCOMES: No postoperative complications were observed. A six-month follow-up revealed no recurrence. LESSONS SUBSECTIONS: Although breast schwannoma is a very rare tumor, it is a very important consideration in case of a Breast Imaging-Report and Data System 4A lesion with a painful and palpable mass.

We report the case of a 65-year-old woman who underwent breast-conserving surgery (BCS) and radiotherapy for breast cancer with hyperpigmentation and skin thickening of the treated breast site 10 years after the surgery. The patient was injected with a liquid foreign body in both breasts 30 years ago. Theses clinical features were considered scleroderma, post-irradiation morphea (PIM), and recurrent breast cancer for differential diagnosis. We performed breast magnetic resonance imaging (MRI), however, the patient had no abnormal findings. Owing to the pain, increased hyperpigmentation, and possibility of cancer recurrence, the patient underwent a simple mastectomy. The final pathologic diagnosis was oleoma with post-radiation fibrosis among drug-induced and toxic scleroderma-like disorders. The patient tolerated surgical therapy without complications. This case report highlight is that difficult to distinguish between PIM and oleoma in patients with a complex history. In this case, the patient had both a history of radiotherapy and a history of foreign body injection, making the clinical diagnosis difficult. PIM and oleoma are non-malignant but can impair a patient's quality of life owing to symptoms and the clinical presentation is similar to that of local recurrence of breast cancer. Thus, arriving at the correct diagnosis typically requires a multidisciplinary approach, including imaging follow-up, skin punch biopsy, or surgery for a definitive diagnosis.
RESUMEN
RATIONALE: Cervical chondrocutaneous branchial remnants are rare, benign, congenital anomalies, frequently seen bilaterally. PATIENT CONCERNS: Here, we report the case of a 4-month-old female infant who presented with bilateral lower neck skin tag since birth. DIAGNOSIS AND INTERVENTIONS: The patient underwent mass excision. The final pathological diagnosis was bilateral cervical chondrocutaneous branchial remnants with hyaline cartilage. OUTCOMES: No complications were observed after excision. One-year follow-up revealed no recurrence. LESSONS: Bilateral chondrocutaneous branchial remnants are rare anomalies. They are often associated with cardiac or genitourinary abnormalities. Therefore, additional preoperative imaging of the abdomen and heart are recommended.

BACKGROUND: Laryngeal ultrasound (LUS) is a new method for vocal cord evaluation in patients with risk of vocal cord palsy (VCP). However, the previously described LUS reportedly had a high failure rate of vocal cord visualization in male patients. A novel gel pad LUS was devised to overcome the limitations of the previous method. METHODS: A total of 482 (100 male) consecutive LUS and direct laryngoscopy examinations were performed in thyroidectomy and other neck surgery patients. The conventional LUS and gel pad LUS were used for all patients. Findings were independently cross-validated with direct laryngoscopy. RESULTS: The conventional LUS and gel pad LUS methods had a 93.4% and 99.0% visualization rate, respectively, with a sensitivity of 98.0% for both methods, and a specificity of 99.7% and 99.8%, respectively. Among the 482 patients, 51 patients had VCP and 91 patients had diffuse thyroid cartilage calcification interrupting LUS. CONCLUSION: The new gel pad LUS method significantly enhances the visualization of vocal cords in patients who have diffuse thyroid cartilage calcification interrupting LUS and, therefore, the overall efficacy of LUS as a perioperative diagnostic tool for VCP.
