Unmasking the Hidden Invader: A case report of chest wall tuberculosis presenting as an abscess.

Chest wall tuberculosis is a very rare clinical entity that accounts for 1-5% of musculoskeletal tuberculosis (TB). Here we present a case of chest wall TB. A 16-year-old boy presented with complaints of progressive increasing swelling over the right hemithorax following a history of trauma. Radiologically it was a localized liquid collection with no connection to the thoracic cavity. Pus sample was sent to the mycobacteriology laboratory. The Gene Xpert result came as positive, and sensitive to rifampicin while the acid-fast bacilli (AFB) smear test was negative. Diagnosing a case of chest wall TB is always challenging for clinicians.

Pulmonary and thoracic infection by Fusobacterium nucleatum. / Infección pulmonar y torácica por Fusobacterium nucleatum.

INTRODUCTION: Fusobacterium nucleatum is an anaerobic bacillus that is part of the oral microbiota and dental pla que. This can cause local and potentially remote infections, which are exceptional in pediatrics. Ob jective: To present the case of a patient with lung injury with chest wall invasion by Fusobacterium nucleatum. CLINICAL CASE: An 11-year-old female immunocompetent patient who consulted due to a two-week history of cough, night sweats, without fever or weight loss, and increased volume at the left spleen thoracic level. There was no history of chest wall trauma or travel outside the country. Two weeks before the onset of symptoms, she was treated for dental caries. Imaging studies and CT scan showed left spleen pneumonia, which invades the pleura and the chest wall. A minimal thoracotomy was performed, releasing a thick, foul-smelling liquid. The studies for common germs and tubercu losis were negative. Hematology ruled out tumor lesions. The anaerobic study reported the develo pment of Fusobacterium nucleatum. The patient was treated with penicillin followed by amoxicillin presenting good clinical and radiological responses. The dental procedure was suspected as the cause of infection. CONCLUSIONS: Fusobacterium nucleatum can occasionally cause remote or extra-oral in fections in immunocompetent patients, such as pneumonia with chest wall invasion, therefore it is necessary to bear it in mind.

Chest wall pseudotumor: a case of non-tuberculous mycobacterial infection.

BACKGROUND: Non-tuberculous mycobacterial (NTM) infections are increasing worldwide, making them an international public health problem. Surgical management is often indicated for localized infectious disease; however, most surgeons are unaware of the potential risks of transmission during surgery. CASE PRESENTATION: An 88-year-old Asian female was referred to our hospital for a tumor in the right lateral thoracic region. One month prior, she had a feeling of fullness and complained of localized pain and warmth in the right lateral thoracic wall. Pain and warmth gradually resolved without intervention; however, the fullness was getting worse. Computed tomography (CT) scan showed a mass of approximately 65 × 30 mm with an osteolytic change, involving the right 8th rib. Based on the rapid growth rate and CT findings, we strongly suspected a malignant chest wall tumor, and en bloc tumor resection with the 8th rib was performed. When the specimen was cut, a large amount of viscous pus was drained and its culture showed growth of Mycobacterium avium. Microscopically, the non-caseating epithelioid cell granuloma extended into the rib, infiltrating the bone cortex. On follow-up 1 month after discharge, there were no signs of infection or other adverse events associated with the surgery. CONCLUSIONS: Herein, we report about a patient with a mass diagnosed as an NTM abscess involving the rib cage, which was confused with a malignant tumor and eventually diagnosed following surgical excision. This report emphasizes the need to be aware of the possibility of NTM infection and take appropriate precautions if the patient has a rapidly growing mass in the chest wall.

Metastatic tuberculous chest wall and massive psoas abscesses in an immunocompetent patient.

Extrapulmonary tuberculosis (TB) is rare in immunocompetent healthy adults. TB of the chest wall accounts for 1%-5% of all cases of musculoskeletal TB. Psoas abscess can be either primary or secondary to diseases like Pott's spine. We describe a patient with massive lower chest wall abscess extending to abdominal muscles and an asymptomatic large psoas abscess detected on imaging due to spine TB which responded well to antitubercular therapy and drainage without surgical measures. The concomitant presence of a massive chest wall abscess and psoas abscess due to TB in an immunocompetent patient was not reported previously.

Osteoarticular Infections of the Chest Wall Due to Kingella Kingae: A Series of 8 Cases.

Osteoarticular infections of the chest wall are relatively uncommon in pediatric patients and affect primarily infants and toddlers. Clinical presentation is often vague and nonspecific. Laboratory findings may be unremarkable in osteoarticular chest wall infections and not suggestive of an osteoarticular infection. Causative microbes are frequently identified if specific nucleic acid amplification assays are carried out. In the young pediatric population, there is evidence that Kingella kingae is 1 of the main the main causative pathogens of osteoarticular infections of the chest wall.

Don't Let Its Name Fool You: Relapsing Thoracic Actinomycosis Caused by Pseudopropionibacterium propionicum (Formerly Propionibacterium propionicum).

BACKGROUND Pseudopropionibacterium propionicum was called Propionibacterium propionicum until a recent taxonomy change in 2016. Diseases caused by P. propionicum resemble actinomycosis and thus differ dramatically from the infectious syndromes caused by common cutaneous Propionibacterium spp. However, if treating physicians are not familiar with P. propionicum and its clinical presentations, it is possible for them to regard it as a skin contaminant such as Cutibacterium acnes (formerly Propionibacterium acnes). CASE REPORT A 71-year-old man with past surgical history of right pneumonectomy was admitted with right chest wall abscess and right empyema. The chest wall abscess was drained surgically, and the empyema was drained via a chest tube. The abscess culture took 5 days to grow beaded branching Gram-positive rods, and 15 days to identify them as P. propionicum. The patient received 17 days of ceftriaxone and 4 weeks of doxycycline. However, he experienced a relapse of the chest wall abscess and right empyema 4 months after discontinuation of doxycycline. Cultures from the chest wall abscess and empyema grew P. propionicum again. We treated him with ceftriaxone for 6 months followed by minocycline for 7 months along with adequate drainage. CONCLUSIONS It is important to recognize that P. propionicum can cause thoracic actinomycosis and will likely require the prolonged treatment course typical for actinomycotic disease, which is 2 to 8 weeks of intravenous antibiotic therapy followed by 6 to 12 months of oral antibiotic therapy.

Chest Wall Reconstruction with a Bilayered Wound Matrix Mesh Following Toilet Mastectomy.

BACKGROUND Breast cancer is still the most common malignancy in women. Though management of local disease has been thoroughly studied, management of metastatic breast cancer (MBC) is still under much debate. Modern diagnostic tools allow the detection of early metastatic disease, which may be more responsive to treatment than late metastatic disease. Source control of MBC by "toilet mastectomy" is being studied in many case reports and studies. CASE REPORT We present the case of a 43-year-old woman presenting with MBC and complaining of a recurrent breast fungating disease, aiming to highlight the importance of palliative surgical treatment in systemic breast malignancy and to report our experience with the effectiveness of the 'Integra" mesh. CONCLUSIONS Chest wall reconstruction using bilayered wound matrix mesh following "toilet mastectomy" offers excellent reconstructive results and local control of disease, and is a low-morbidity procedure.

Tuberculous retropharyngeal abscess with Pott disease and tuberculous abscess of the chest wall: A case report.

RATIONALE: Tuberculous retropharyngeal abscess is rare, but it can be fatal if not treated appropriately. It usually occurs secondary to tuberculosis of the cervical spine. Moreover, tuberculous abscess involving the chest wall is relatively rare in skeletal tuberculosis. Although the optimal treatment is controversial, most clinicians suggest a combination of sufficient antituberculous medication and complete resection to prevent recurrence and increase therapeutic efficacy. Herein, we present an unusual case of retropharyngeal abscess with cervical Pott disease and tuberculous abscess of the chest wall. PATIENT CONCERNS: The patient was a 27-year-old Indonesian woman who had neck pain, dysphagia, and odynophagia, but no neurological deficit. Examination of the oral cavity showed anterior displacement of the posterior pharyngeal wall. The mass over the right anterior chest wall measured approximately 5 × 4 cm in size. DIAGNOSES: Radiography and computed tomography findings were suggestive of retropharyngeal abscess extending to the cervical spine and chest wall abscess. INTERVENTIONS: She was admitted to the hospital for treatment. Drainage of the retropharyngeal and chest wall abscesses with debridement of the chest wall was performed. OUTCOMES: No complications occurred after early surgical treatment and administration of antituberculous medication. The patient recovered well and went back to her own country after discharge. LESSONS: Tuberculous retropharyngeal abscess with Pott disease and tuberculous abscess of the chest wall are both complicated diagnoses that physicians have to consider in similar patient presentations.

Cold abscess in the immunocompetent subject.

INTRODUCTION: Tuberculous cold abscesses are a rare and unusual form, accounting for 1% of extrapulmonary tuberculosis (TB). AIM: To describe clinical, diagnostic, therapeutic and prognostic aspects of cold tuberculous abscesses. METHODS: Retrospective multicentre study of 26 patients followed for cold abscesses tuberculous in respiratory departments of AbderrahmenMami hospital between 2009 and 2017. RESULTS: We included 24 patients. Mean age was 36.9 years. Six patients had a personal history of pulmonary TB. Circumstances of the discovery were chronic pain (n = 15), parietal swelling (n = 7) and parietal fistulization (n = 2). The mean duration of the symptoms was 2.8 months. Fever was absent in 15 patients. The cold abscess was multifocal in 3 patients, associated with pleuropulmonary TB in 16 patients and extrapulmonary TB in 9 patients. Thoracic wall was the most frequent localization (n=13), followed by subcutaneous and intramuscular localization (n = 6). The surgical flattening of the abscess with biopsy of the edges was performed in 15 patients. The positive diagnosis was pathological in 15 patients and bacteriological in 12 patients. GeneXpert was positive in 2 patients. All patients received anti-tuberculosis treatment. The mean duration of TB was 10.7 months. Evolution was marked by the cure of 20 patients and tuberculous relapse in 1 patient after 6 months. CONCLUSION: Tuberculous cold abscess should be evoked in front of any chronique collection occurring especially in a context of risk factors of TB. Early diagnosis is the best guarantee of a cure without complications.

Primitive necrotizing fasciitis of the thoracic wall: Fatal complication of diabetic patient.

INTRODUCTION: necrotizing fasciitis of the chest wall is a rare condition in subcutaneous tissues and deep fascia. Primary thoracic involvement is exceptional and is a diagnostic and therapeutic emergency. AIM: To report our experience in the management of this rare pathology of which clinical picture is unknown by most practitioners. METHODS: This is a retrospective study carried out over a period of 07 years, compiling 07 cases of primitive necrotizing fasciitis of the thoracic wall at the department of thoracic surgery at the CHU Hassan II in Fez. RESULTS: Patients were five men and two women, with an average age of 58 years. All our patients were known to have poorly balanced diabetes. The reason for consultation was a swelling of the chest wall with fever in all patients. On the results of thoracic computed tomography (CT), the presence of a deep collection of soft tissue was found   in all patients. The treatment was a large necrosectomy, taking away the skin as well as the adjacent muscle. Postoperative follow-up was favorable in five patients. We noted two deceased patients due to postoperaive septic shock. CONCLUSION: Necrotizing chest wall fasciitis is a medical and surgical emergency, requiring early diagnosis and rapid and appropriate management which will determine the prognosis.

Late-onset chest wall abscess due to a biodegradable rib pin infection after lung transplantation.

A 55-year-old man with end-stage emphysema underwent a right single-lung transplantation through a posterolateral thoracotomy. The fifth rib was divided and fused back using a biodegradable pin made of polylactide acid and hydroxyapatite. Two weeks postoperatively, he suffered from central vein catheter-related sepsis due to methicillin-sensitive Staphylococcus aureus. After being successfully treated for sepsis, he was discharged. However, 3 months later, computed tomography revealed multiple loculated abscesses in the chest wall and the right pleural space. Reoperative thoracotomy revealed abscesses mainly located around the fifth rib, where the pin was inserted. Both cultures of the abscess and the fifth rib were positive for methicillin-sensitive S. aureus, which suggested that the rib pin was the cause of the secondary infection. This case suggests the rib pins, even if they are biodegradable, could have a risk of infections side effect especially for the immunosuppressed patients.

[Tuberculosis Abscess of the Chest Wall on an Immunocompetent Patient in the Teaching Hospital of Dakar (Senegal)]. / Abcès tuberculeux de la paroi thoracique chez une patiente immunocompétente au centre hospitalier universitaire de Dakar (Sénégal).

Tuberculosis remains a problem of public health, in spite of the numerous significant advances noted in the diagnosis in recent years. The involvement of the thoracic wall is a rare extra lung shape. Its clinical presentation is not specific and a collected thoracic tumefaction is the main clinical demonstration. The diagnosis is improved by the use of non-invasive tools such as the Xpert MTB/Rif® test with a good sensibility on the pus. Medical care is based on medical treatment and sometimes associated with surgical treatment.

La tuberculose demeure un problème de santé publique, malgré les nombreuses avancées significatives notées dans le diagnostic ces dernières années. L'atteinte de la paroi thoracique est une forme extrapulmonaire rare. Sa présentation clinique est non spécifique, et une tuméfaction thoracique collectée en est la principale manifestation clinique. Le diagnostic est amélioré par l'utilisation d'outils non invasifs tels que le test Xpert MTB/Rif® avec une bonne sensibilité sur le pus. La prise en charge repose sur le traitement médical quelquefois associé à un traitement chirurgical.

[Tuberculous abscess of the thoracic wall secondary to nodular tuberculosis: Atypical presentation in an older adult]. / Absceso tuberculoso de pared torácica secundario a tuberculosis ganglionar; presentación atípica.

Tuberculosis (tb) of the chest wall is uncommon and it represents less than 5% of all cases of musculoskeletal tb and only 1-2% of tb. We present the case of an elderly woman with tb of the chest wall secondary to a nodal tb with an unusual presentation. The diagnosis of this entity is difficult because the disease often mimics other diseases such as pyogenic abscess, chest wall.

Clinical, diagnostic, and therapeutic features of patients admitted to acute care hospitals with trunk compared to lower limb cellulitis.

The objective of this study is to report the clinical course and risk factors of trunk cellulitis, to identify diagnostic and therapeutic approaches, and compare them to patients with lower limb cellulitis. Medical records of adult patients with trunk cellulitis were reviewed and compared to an equal number of randomly selected patients with lower limb cellulitis. Demographic, clinical, and laboratory data were collected and analyzed using binary univariate and multivariate logistic regression analyses. Primary outcome was surgical drainage. Secondary outcomes were use of imaging studies, length of stay, readmission within 30 days, and 30-day mortality. During the study period, 74 patients were diagnosed with trunk cellulitis. Compared to patients with lower limb cellulitis, there are more women (57 vs. 39%, p = 0.032) and they are younger (mean age 59.7 vs. 68.4 years, p = 0.005). The only co-morbidity found as a significant risk factor for trunk cellulitis is malignancy (p = 0.017). These variables remain independent risk factors for trunk cellulitis after multivariate regression analysis. There is a trend toward more surgical interventions in the study group [6 (8%) patients vs. 1 (1%) with leg cellulitis, p = 0.116], and a longer hospital stay (5.8 days in the study group vs. 4.3 days in the control group, p = 0.025). Laboratory data are similar in both groups. There are risk factors for trunk cellulitis compared to lower limb cellulitis. However, diagnostic and therapeutic approaches are similar, except for a trend for more surgical interventions.
