Co-occurrence of posterior chest wall pilonidal sinus with melanocytic nevus: a challenging presentation: a case report.

INTRODUCTION: To date, only a limited number of case reports have documented the co-occurrence of PNS and melanocytic nevus in the medical literature. This study aims to report an exceptionally rare case of posterior chest wall PNS in conjunction with a melanocytic nevus. CASE PRESENTATION: A 46-year-old female presented with a long-standing black lesion on her left upper posterior chest wall, that had become painful in the two months prior to presentation. There was a painful, dark blue, non-erythematous, and non-tender nodule on the left upper posterior chest wall. Based on the patient's desire for cosmetic purposes, the lesion was excised totally with primary closure under local anaesthesia. Histopathological examination revealed intradermal melanocytic nevus with inflamed pilonidal sinus. DISCUSSION: The rarity of posterior chest wall PNS associated with nevi poses unique diagnostic and therapeutic challenges for clinicians. The distinct anatomical location, different from the conventional region, and the rare association between the two conditions may delay accurate diagnosis and result in mismanagement or inappropriate interventions. CONCLUSION: The posterior chest wall PNS is another type of atypical PNS that is extremely rare. The association between PNS and blue nevus is a fascinating medical finding that deserves further investigation.

Postoperative Complications of Flap Procedures in Chest Wall Defect Reconstruction: A Two-Center Experience.

Background and Objectives: Chest wall defect reconstruction is a complex procedure aimed at restoring thoracic structural integrity after trauma, tumor removal, or congenital issues. In this study, postoperative complications were investigated to improve the care of patients with these critical conditions. Materials and Methods: A retrospective study of chest wall reconstructions from 2004 to 2023 was conducted at Klinikum Nürnberg and Evangelisches Waldkrankenhaus Spandau-Berlin. Data included patient demographics, comorbidities, defect etiology, surgery details, and complications using the Clavien-Dindo classification. Results: Among the 30 patients included in the study, a total of 35 complications occurred in 35 thoracic wall defect reconstructions. These complications were classified into 22 major and 13 minor cases. Major complications were more common in patients with cancer-related defects, and considerable variations were observed between free flap and pedicled flap surgeries. Notably, the use of the anterolateral thigh (ALT) flap with vastus lateralis muscle demonstrated promise, exhibiting fewer complications in select cases. The reconstruction of chest wall defects is associated with substantial complications regardless of the etiology of the defect and the particular surgical procedure used. Interestingly, there was a lower complication rate with free flap surgery than with pedicled flaps. Conclusions: The ALT flap with vastus lateralis muscle deserves further research in this field of reconstruction. Multidisciplinary approaches and informed patient discussions are crucial in this complex surgical field, emphasizing the need for ongoing research and technique refinement.

Comprehensive analysis of donor-site chest deformities after autologous costal cartilage microtia reconstruction: A systematic review.

BACKGROUND: Autologous costal cartilage has gained widespread acceptance as an important material for ear reconstruction in patients with microtia. Despite its recognition as being "worth the trade-off," attention should be directed toward donor-site deformities. This systematic review focused on existing English literature related to microtia reconstruction and aimed to reveal the incidence of chest wall deformities and assess the effectiveness of the various proposed surgical techniques aimed at reducing donor-site morbidities. METHODS: A comprehensive search was conducted on Pubmed and OVID using the keywords "microtia," and "chest deformity" or "rib harvest." Articles were screened based on predefined inclusion and exclusion criteria. Data acquisition encompassed patient demographics, employed surgical techniques, methods for evaluating chest deformity, and incidence of associated complications. RESULTS: Among the 362 identified articles, 21 met the inclusion criteria. A total of 2600 cases involving 2433 patients with microtia were analyzed in this review. Perichondrium preservation during cartilage harvesting led to a significant reduction in chest deformities. However, the wide incidence range (0% to 50%) and the lack of specific assessment methods suggested potential underestimation. Computed tomography revealed reduced chest wall growth in the transverse and sagittal directions, resulting in decreased thoracic area. Innovative surgical techniques have shown promising results in reducing chest deformities. CONCLUSIONS: Although a quantitative analysis was not feasible, objective evidence of deformities was established through computed tomography scans. This analysis highlighted the need for dedicated studies with larger sample sizes to further advance our understanding of chest wall deformities in microtia reconstruction.

[Combined surgeries for secondary chest wall lesions]. / Kombinirovannye operatsii pri vtorichnom porazhenii grudnoi stenki.

A minimally invasive hybrid procedure to correct pectus arcuatum.

BACKGROUND: Pectus arcuatum, also known as horns of steer anomaly or Currarino-Silverman Syndrome, is a distinct chest wall anomaly characterized by severe manubriosternal angulation, a shortened sternum, and mild pectus excavatum. The anomaly is typically repaired using open techniques, employing orthopedic fixation devices. Here, we report the results of a minimally invasive hybrid procedure to repair pectus arcuatum. METHODS: The procedure combines a standard Nuss procedure to correct the depressed sternum with a short upper chest (in boys) or inter-mammary (in girls) incision for bilateral subperichondrial resection of the upper costal cartilages, osteotomy, and correction of the manubrial angulation. The medical records of all patients who underwent the procedure over the last 10 years were reviewed. RESULTS: Five patients, 3 boys and 2 girls, aged 14 to 17 years, underwent the procedure. Three patients had their pectus bars removed 3-4 years after repair. Follow-up after correction ranged from 6 months to 7 years. Good correction resulted in all patients achieving recovery without complications and recurrence. To date, all patients have been satisfied with their results. CONCLUSIONS: The minimally invasive hybrid procedure adequately corrects pectus arcuatum with minimal scarring and high satisfaction.

Resection to restoration: Assessing the synergy of polypropylene mesh (Marlex®) combined with methyl-methacrylate and latissimus dorsi flap for primary chest wall sarcomas.

BACKGROUND: Chest-wall sarcomas are treated with extensive resections and complex defect reconstruction to restore chest-wall integrity. It is a difficult surgical procedure that incorporates a multidisciplinary approach for the best outcome, preventing paradoxical chest movement issues and reducing complications. OBJECTIVE: We aimed to describe our experience of chest-wall reconstruction using polypropylene mesh (Marlex® Mesh) combined with methyl-methacrylate and soft-tissue coverage with a latissimus dorsi flap following sarcoma resection. PATIENTS AND METHODS: Among the 53 patients treated for primary chest-wall sarcomas at the European Institute of Oncology (IEO) in Milan, Italy, from 1998 to 2020, 14 cases underwent chest-wall resection and reconstruction using polypropylene mesh, methyl-methacrylate and the latissimus dorsi flap. Patients with locally advanced breast cancers, locally advanced lung cancers, squamous cell carcinomas, and other secondary chest-wall malignancies were excluded from the study, as were the patients with different types of chest-wall reconstruction. RESULTS: In this study, 14 patients (6 men and 8 women) with various primary chest-wall sarcomas were enrolled. On an average, 2 ribs (range: 1-5) were removed during the surgeries, and the chest-wall defects ranged from 20 to 150 cm2 with an average size of 73 cm2. The mean follow-up period for these patients was approximately 63.80 months CONCLUSION: The combination of Marlex® mesh filled with methyl-methacrylate and covered using latissimus dorsi myocutaneous flap provides safe, low-cost and effective single-stage chest-wall reconstruction after surgery for primary sarcomas.

Reconstruction method for massive lateral chest wall sarcoma using titanium plates and mesh: a case report.

BACKGROUND: Very large chest wall resections can lead to acute thoracic insufficiency syndrome due to the interdependence of lung expansion and thoracic volume. Chest wall tumor surgeries often encounter complications, with the size of the chest wall defect being a significant predictor. Several methods for large chest wall reconstruction have been described, aiming to provide stability, prevent flail chest, and ensure airtight closure. However, no single method fulfills all requirements. Composite chest wall reconstruction using titanium plates and Gore-Tex patches has shown the potential to minimize physiologic abnormalities caused by extensive defects. CASE PRESENTATION: A 42-year-old man with myxofibrosarcoma underwent multiple surgeries, chemotherapies, and radiation therapies due to repeated local recurrences. After right arm amputation and resection of the right third to fifth ribs, a local recurrence was detected. A 30 × 40 cm chest wall defect was resected en bloc, and a titanium plate was used for three-dimensional formability, preventing flail chest and volume loss. The Gore-Tex patch was then reconstructed into an arch shape, allowing lateral thoracic mobility. The patient recovered well and did not experience respiratory dysfunction or local recurrence but later succumbed to distant metastasis. CONCLUSIONS: In this case, the combination of a titanium plate and a Gore-Tex patch proved effective for reconstructing massive lateral chest wall defects. The approach provided stability, preserved thoracic volume, and allowed for lateral mobility. While the patient achieved a successful outcome in terms of local recurrence and respiratory function, distant metastasis remained a challenge for myxofibrosarcoma patients, and its impact on long-term prognosis requires further investigation. Nevertheless, the described procedure offers promise for managing extensive chest wall defects.

Surgical Resection of Giant Chest Wall Chondrosarcoma Combined with Sandwich Chest Wall Reconstruction in One Case.

INTRODUCTION: Primary chest wall tumors account for 5% of all thoracic neoplasms and 1% of all primary tumors. Chondrosarcoma is a rare solid tumor, with an annual incidence of <0.5 per million people per year. It predominantly occurs in the pelvis and femur, occasionally occurs in flat bones such as the sternum and ribs, and rarely invades lung tissue. Chest wall chondrosarcomas represent only 5-15% of all chondrosarcomas. Radical surgery often leads to a large range of chest wall defects, especially when the range exceeds 6 cm × 6 cm and involves the sternum, spine, or multiple consecutive ribs. The reconstruction of the chest wall bone should be considered to restore the integrity and stability of the chest, prevent chest wall softening and abnormal breathing, and ensure the stability of respiratory circulation. Chest wall reconstruction can help restore thoracic hardness and integrity, prevent lung hernia and abnormal breathing, while also ensuring a positive aesthetic outcome. The chest wall reconstruction includes reconstruction of the pleura, bony structures, and soft tissues. CASE REPORT: In our case of an adult male, after the resection of the third and fourth anterior rib chondrosarcoma, the common anatomical plate was shaped and fixed to the stump of the third rib with screws to ensure the stability of the thorax while retaining the mobility of the thorax. After applying hernia mesh pruning, the chest wall defect was stitched to complete the pleural reconstruction of the defect area. This procedure can effectively maintain the stability of the pleural cavity, provide more effective support for the chest wall soft tissue, and promote the recovery of upper limb function and lung function. CONCLUSION: The radical surgery of giant chest wall chondrosarcoma often leads to a large range of chest wall defects. Chest wall reconstruction needs to be carried out at the same time to restore the integrity and stability of the chest wall, to avoid chest wall softening and abnormal breathing, and to ensure the stability of respiratory circulation. Using the "sandwich" method for chest wall reconstruction, in which an anatomical plate is combined with hernia mesh and muscle soft tissue, and during which pleura, bony structure, and soft tissues are reconstructed, can provide more effective support for chest wall soft tissue, effectively prevent postoperative muscle tissue collapse, avoid postoperative abnormal breathing, and promote the recovery of postoperative upper limb function and lung function. It is a very effective method for chest wall reconstruction.

Mind the gap! Interdisciplinary approach to anterior chest wall reconstruction after total sternectomy.

BACKGROUND: There are various reconstructive methods after total sternectomy. Reproducibility is scarce due to overall small patient numbers. Therefore we present a standardized, interdisciplinary approach for thoracic and plastic surgery. METHODS: Four patients underwent interdisciplinary chest wall reconstruction with STRATOS® titanium bars and myocutaneous vastus lateralis muscle free flap in our center. RESULTS: All patients reported chest wall stability after reconstruction. They reported good quality of life, no dyspnea, prolonged pain or impairment in lung function from rigid reconstruction. FEV1/FVC was overall better after surgery. Secondary wound healing was not impaired and there was no implant defect in follow up. CONCLUSIONS: We recommend an interdisciplinary surgical approach in chest wall reconstruction after total sternectomy. The combination of rigid reconstruction with titanium bars and a myocutaneous vastus lateralis muscle free flap renders excellent results in patient satisfaction and is objectifiable via spirometry.

Ewing Sarcoma-Chest Wall Reconstruction Following Resection of Rare Primary Chest Wall Tumor.

Ewing sarcoma (ES) represents the second most common primary osseous malignancy in children and young adults, most often occurring in the diaphysis of the long bones. While rare, ES can present as an osseous tumor of the ribs and/or chest wall. These tumors are known as Askin's tumors and most commonly present with symptoms resembling pneumonia. We report the case of a 26-year-old man who was found to have a right lung mass extending into his anterolateral chest wall after presenting to the hospital for evaluation of unremitting chest pain. Biopsy was performed and the patient diagnosed with ES. After completion of neoadjuvant chemotherapy, the patient underwent resection of the right chest wall mass. The chest wall was reconstructed in a novel fashion with titanium plates and a reinforced tissue matrix patch. Due to a paucity of cases, no treatment or reconstruction algorithm currently exists for management of these malignancies.

Impact of delayed removal of pectus bar on outcomes following Nuss repair: a retrospective analysis.

BACKGROUND: Usually, pectus bars are removed 3 years after the Nuss procedure in patients with pectus excavatum. However, the optimal timing for postoperative pectus bar removal remains undefined. Our study investigated the effects of delayed pectus bar removal after Nuss repairs. METHODS: Retrospective data were collected on patients who underwent Nuss procedures for pectus excavatum and had their bars removed from August 2014 to December 2020. Patients with correction periods > 3 years were divided into group A (< 6 years) and group B (≥ 6 years). Propensity score matching was used to compare complications and radiological outcomes associated with bar removal. RESULTS: Of the 542 patients who underwent bar removal, 451 (Group A: 419 patients, Group B: 32) had correction duration > 3 years. The average correction duration was 4.5 ± 1.4 years. After propensity score matching analysis, group B [median duration: 8.0 (6.0-16.2) years] exhibited significantly longer median operative times (85 vs. 55 min; P = 0.026), higher callus formation rates (68.8% vs. 46.9%; P = 0.029), and greater median intraoperative blood loss (35 vs. 10 mL; P = 0.017) than group A [median duration: 4.2 (3.0-5.9) years]. However, following bar removal, the groups showed no statistical differences in the surgical complication rates (group A: 6.3% vs. group B: 9.4%; P = 0.648) or median ratio of radiological improvement (an improvement on the Haller index on chest radiography; 21.0% vs. 22.2%; P = 0.308). CONCLUSIONS: Delaying pectus bar removal after Nuss repair presents certain challenges but does not compromise overall outcomes. These findings suggest that a longer correction period may be unnecessary. However, further multicenter studies with long-term follow-up are warranted to assess long-term outcomes.

Chest wall resection with robotic-assisted thoracoscopic surgery for a Pancoast tumour: a case report.

We describe a rare procedure involving near-total robotic-assisted thoracoscopic surgery resection of a right posterior Pancoast tumour. Four ports and an assistant port were used. The DaVinci X system was used. The lobectomy was performed first to allow for adequate exposure to the apex and spine. The lateral aspect of ribs 1 to 4 was resected next, and the extrathoracic space was entered. Dissection proceeded through this space superiorly up to the level of the scapula and then posteriorly towards the spine. The second to the fifth ribs were dissected off the chest wall and resected medially off the spine at the rib heads. Further postero-superior exploration revealed the tumour to be invading the transverse process of the second rib, with ill-defined margins. Because of this development, and with the support of the spinal surgeons, a small high posterior thoracotomy was performed to complete the procedure and remove the specimen en bloc. The postoperative recovery was uneventful, and the patient was discharged on post-operative day 5. The final histological report confirmed a squamous non-small-cell lung cancer (pT3N0M0) with negative margins (R0). Asymptomatic recurrence was noted near the margin of the second rib resection posteriorly 1 year postoperatively and was successfully treated with radiotherapy.

Microsurgical reconstruction using thoracoacromial vessels as recipients for complicated chest wall defects.

BACKGROUND: Free tissue transfer is often required for the reconstruction of complex and deep anterior chest wall wounds, for which the identification of suitable recipient vessels is crucial. Although the internal mammary arteries (IMAs) are a representative option, identifying secondary options when these vessels are compromised remains a challenge. This report evaluated the efficacy of using the thoracoacromial vessels (TAVs) as recipients for chest wall reconstruction by reviewing our experience. METHODS: We conducted a retrospective review of patients undergoing free-flap-based chest wall reconstruction using TAVs as recipient vessels from February 2020 to March 2023. Patient demographics and surgery-related characteristics data were collected. The primary outcome of interest was the occurrence of flap perfusion-related complications. RESULTS: In total, 12 cases utilized TAVs as recipients, primarily for defects following sternotomy, where bilateral IMA was unavailable due to prior surgery. The TAVs with reliable perfusion were consistently identified beneath the pectoralis major muscle. The anterolateral thigh flap was predominantly employed, with musculocutaneous or chimeric flaps introduced for bony defects. The mean pedicle length of the harvested flap was 7.2 cm (range, 3-13), and in cases with a vascular gap, the pedicle was extended using an arteriovenous interposition graft. This resulted in a mean pedicle length needed to reach recipient vessels of 9.9 cm (range, 6.5-19). All flaps survived, with only one experiencing partial necrosis. CONCLUSIONS: The TAV could be considered as an attractive alternative recipient vessel in microsurgical reconstruction of complicated chest wall defects when the use of IMA is not feasible.

[Surgical treatment of extensive metastatic tumor of the left ribs III-V and lung in 13 years after resection of cylindroma of the soft palate]. / Khirurgicheskoe lechenie obshirnoi metastaticheskoi opukholi III­V reber i legkogo sleva spustya 13 let posle udaleniya tsilindromy myagkogo neba.

Metastatic chest lesion is rare in patients with soft palate tumors. We present a 52-year-old patient with metastatic lesion of the left ribs III-V and lung in 13 years after resection of cylindroma of the soft palate. The patient underwent successful chest reconstruction and atypical resection of the left lung. Isolation of the pleural cavity by xenopericardial patches and preoperative 3D CT modeled titanium implants meet all the requirements for maintaining the chest function. This approach also positively affects postoperative period and recovery. The above-described method of replacing chest defects is highly effective.

An innovative reconstruction of an enbloc resected composite giant chest and abdominal wall chondrosarcoma with 3D-composite mesh.

BACKGROUND: Chest wall chondrosarcomas, although common, pose unique challenges due to their aggressive nature, rarity of abdominal wall involvement, and propensity for recurrence. We highlight the critical role of meticulous surgical planning, multidisciplinary collaboration, and innovative reconstruction techniques in achieving optimal outcomes for patients with composite giant chest and abdominal wall chondrosarcoma. CASE PRESENTATION: A 38-year-old female patient presented with progressive left chest and abdominal wall swelling for two years; on evaluation had a large lobulated lytic lesion arising from the left ninth rib, scalloping eighth and tenth ribs measuring 13.34 × 8.92 × 10.71 cm (anteroposterior/transverse/craniocaudal diameter) diagnosed with chondrosarcoma grade 2. A three-dimensional (3D) composite mesh was designed based on computed tomography using virtual surgical planning and computer-assisted design and manufacturing technology. She underwent wide local excision and reconstruction of the chest and abdominal wall with 3D-composite mesh under general anesthesia. The postoperative condition was uneventful, with no recurrence at 12 months follow-up. CONCLUSION: A 3D-composite mesh facilitates patient-specific, durable, and cost-effective chest and abdominal wall reconstruction.

Curved Axillary Incision with Video-Assisted Thoracoscopic Surgery: An Alternative Approach for Teenage Female with Large Apical Chest Wall Tumor.

Primary chest wall tumors are rare, their common clinical features are not well known, and surgical resection remains the main treatment. Apical chest wall tumors require large skin incisions and dissection of the chest wall muscles, making it difficult to maintain cosmetic appearance, respiratory function, and support of the upper extremity. There are few treatment options and no studies have reported on thoracotomy that spares muscles and preserves cosmetic superiority. However, in benign chest wall tumors in young patients, it is necessary to consider radicality, cosmetic superiority, and muscle sparing. We used a combined axillary incision and thoracoscopic approach to treat a massive myxoid neurofibroma at the apical chest wall in a 14-year-old female and were able to preserve the chest wall, upper limb function, and cosmetic aspects. This report provides a detailed description of the combined axillary incision and thoracoscopic approach for apical chest wall tumors.

Computer Tomography (CT)-Based Study to Investigate Feasibility and Efficacy of Thoracoscopic Surgery in the Treatment of Penetrating Chest Wall Tuberculosis.

BACKGROUND: Chest wall tuberculosis may develop if tuberculous (TB) lesions spread through the chest wall and invade the thoracic cavity. The presence of a mass on the patient's chest wall may be the first indication of TB, and a chest CT scan can help diagnose external penetrating chest wall TB, the incursion of tuberculosis from the lungs into the chest wall. OBJECTIVE: This study examines the safety and efficacy of thoracoscopic-assisted surgery for the treatment of penetrating chest wall tuberculosis as a means of exploring novel concepts of minimally invasive surgery. METHODS: Our hospital conducted a retrospective study of 25 patients with penetrating chest wall TB who underwent thoracoscopic surgery between January 2020 and June 2021. General demographics, CT scan data linked to surgery, and postoperative patient outcomes were compared between the two groups. The data was also evaluated to determine the range of operation time and the volume of bleeding from different foci in the thoracic cavity. RESULTS: All procedures went well after patients took conventional antituberculosis medication for at least two weeks prior to surgery. CT scans showed that thoracoscopic surgery needed a smaller incision than traditional chest wall TB surgery, with no discernible increase in surgical time. Postoperative tube use, length of hospital stay, and blood loss were all significantly lower than they would have been with conventional surgery. In addition, thoracoscopy was associated with a significantly reduced rate of subsequent treatment. Fibrous plate development and calcification caused the longest operation times in the thoracoscopic surgery group, whereas multiple pleural tuberculomas generated the most hemorrhage. Thoracoscopic surgery usually reveals tuberculous foci hiding in the thoracic cavity. CONCLUSION: Thethoracic surgery can eliminate the TB focus in the chest wall and intrathoracic while treating penetrating chest wall tuberculosis. The CT scan is a crucial part of the diagnostic process for these patients. Minor surgical trauma, low complication and recurrence rates, and good results. There is a greater distinction between the two surgical approaches for patients with penetrating chest wall TB as opposed to those with basic chest wall tuberculosis.

A prospective study evaluating patient reported outcome measures in patients who have undergone chest wall perforator flaps.

AIMS: To evaluate Patient Reported Outcome Measures (PROMs) and surgical outcomes in patients undergoing Chest Wall Perforator Flaps (CWPFs). METHODS: This was an observational single cohort study using an audit approach and a survey instrument. 84 patients who had undergone CWPFs in the last 5 years at the Department of Breast Surgery, City Hospital Birmingham, were identified from a pre-existing database. Surgical outcomes were recorded. Patients were contacted telephonically or in person at the time of follow-up and were asked to fill up a PROMs questionnaire. RESULTS: Out of 84 patients, 58 patients chose to respond. The average age of the patients was 51.3 years (±8.2 years). The average follow-up was 15.4 months (±9.9 months). The most common histological subtype was Infiltrating ductal carcinoma (IDC)-Not otherwise specified 34/58 (58.6%). Majority of the patients had T2 cancers-28/58 (48.3%). 26/58 (44.8%) were node negative. Eight patients (13.7%) had post-operative complications. No patient had total/partial flap loss. Nine patients (15.5%) had margin re-excision. One patient developed distant metastasis while 1 patient developed a second primary. Fifty-one patients (88%) were either satisfied or very satisfied with the post-operative appearance of the breasts. Thirty-six patients (62%) had no/little persistent pain or tenderness post-surgery. Eighty-six per cent (38/44) of the patients undergoing Lateral Intercostal Artery Perforator (LICAP) Flap and 16/18 (89%) of patients undergoing Anterior Intercostal Artery Perforator (AICAP) flap had no/little difficulty in carrying out normal activities at follow up. CONCLUSION: CWPFs are associated with a low complication rate and a high patient satisfaction rate.
