[PMID: 38110259 DOI: 10.1016/j.ijtb.2023.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 09/04/2023] [Accepted: 09/11/2023] [Indexed: 12/20/2023]
Abstract
Tuberculosis and malignancy are major public health problems in developing countries like India and causes significant morbidity and mortality. Mycobacterium tuberculosis is an aerobic acid-fast bacilli which is an important pathogen especially complicating clinical status of paediatric oncology patients and treatment of infection with this bacilli is challenging in this subpopulation of patients because of ongoing immunosuppression and relative lack of published guidelines. Atypical presentations of tuberculosis in children also complicate the diagnosis and management. All the more, in tuberculosis endemic area lung cancer may be mistakenly diagnosed as tuberculosis or vice versa and this wrong diagnosis increases the burden on country's health status. It is noted that tuberculosis prevalence is high in children with haematological malignancy and head and neck tumours compared to other solid organ tumours. Moreover, it is found that morbidity and mortality from tuberculosis is more in children from WHO listed high TB burden countries who undergo hematopoietic stem cell and solid organ transplantation. Use of immune checkpoint inhibitors as novel therapy in treatment of childhood malignancies has led to modification of the body's immunological response and has resulted in increased latent tuberculosis infection reactivation as one immune-related infectious consequence. Latent TB infection screening is important concept in management of paediatric oncology patients. Currently, the tests employed as screening diagnostics for LTBI are interferon-gamma release assay (IGRA) blood test and the tuberculin skin test (TST). Various regimens have been suggested for the treatment of LTBI. But, after a positive IGRA or TST and prior to latent TB treatment, active tuberculosis should be ruled out by detailed history taking, examination and appropriate investigations so as to minimize the risk of drug resistance with anti-tuberculosis monotherapy used in LTBI treatment. To add on to literature, Non tuberculous mycobacteria are universally present environmental organisms. However, in immunocompromised children especially in subpopulation of malignancy, NTM is known to cause infections which needs protocol based management. Also importance has to given to implementation of adequate preventive and corrective measures to prevent such opportunistic infection in paediatric oncology subpopulation. In this review, we provide an overview of tuberculosis in paediatric oncology patients and summarize the expansive body of literature on the tuberculosis mimicking carcinoma, tuberculosis burden in transplantation patients and those receiving immune check point inhibitors, latent TB infection screening and management, and NTM infection in children with malignancy.

Abstract
This report describes three cases of tumour-like pulmonary tuberculosis: two patients had stage C3 human immunodeficiency virus (HIV) infection (with uncontrolled HIV-1 in one case) and one patient was immunocompetent. All patients initially presented with general and respiratory symptoms, with radiological findings simulating lung carcinoma. Tuberculosis was diagnosed from microbiological testing and/or histological examination results. A disseminated form was described in one case. All patients were treated successfully with antimycobacterial therapy, with control of HIV infection in both cases.

Abstract
Pulmonary tuberculosis manifesting as a mass lesion, thus, mimicking a lung carcinoma is an unusual radiographic presentation of tuberculosis (TB). The common radiologic patterns and clinical presentations are well known and documented. We report two cases of pulmonary tuberculosis with a neoplastic appearance on chest imaging diagnosed histologically. A 21 – year old female with cough, weight loss, anorexia and an unremarkable physical examination. Chest radiography showed a right apical mass suggestive of lung cancer. Histology of the lesion revealed parenchymal pulmonary tuberculosis. A 49-year old male with left-sided chest pain, cough, anorexia, weight loss, mild pallor with an unremarkable chest examination. Chest imaging showed a left apical mass and mediastinal lymphadenopathy. Microscopic examination of the mass confirmed pulmonary tuberculosis. Pseudotumour pulmonary tuberculosis is a rare clinical entity that can lead to diagnostic challenges and must be considered in the differential diagnosis when mass lesions are seen on chest imaging, especially in TB endemic areas.

Abstract
Infective and inflammatory diseases can mimic malignancy of the lung. Granulomatous inflammations are common causes of pulmonary nodule, mass, or nodal disease. Systemic infection or inflammation also commonly involves the lung that may raise suspicion of a malignant process. Even in patients with a known malignancy, inflammatory diseases can simulate new metastasis or disease progression. Knowledge of the imaging features of these diseases is essential to prevent missed or overdiagnosis of malignancy. Radiologists also need to be familiar with the scope and limitations of bronchoscopy, endobronchial ultrasound, PET-CT, and biopsy to guide clinical management. In this review, we discuss the imaging features and diagnostic approach of common mimickers of chest malignancy that involve the chest wall, pleura, lung parenchyma, and mediastinal nodes.

Abstract
INTRODUCTION The pseudotumorous form of tuberculosis is a rare entity. Whatever its location, it can simulate neoplasia by its radiological and/or endoscopic appearances. We highlight the diagnostic difficulties associated with this type of presentation. METHODS We performed a retrospective study of inpatient records from 2003 to 2016 in the pneumology department of La Rabta Hospital to identify cases of thoracic tuberculous pseudo-tumor. RESULTS Seventeen patients were identified. The median age was 41 years and their symptomatology was dominated by cough and general debility. All had abnormal radiology with 10 cases of suspect lesions. Fibre-optic bronchoscopy revealed endobronchial abnormalities in 11 cases. The median overall diagnostic delay was 97 days. The diagnosis was confirmed bacteriologically in five cases, histologically in 14 cases and based on clinical presumption in one case. The progression was favourable: 13 patients have been declared cured and four patients are still undergoing treatment. CONCLUSION Making a positive diagnosis of thoracic tuberculous pseudotumour can be difficult, as bacteriological samples are often negative. This can lead to a significant delay in diagnosis and treatment.

Abstract
Tuberculosis (TB) is a major public health problem, invading all age groups world-wide. It is an opportunistic infection affecting the individuals alone or with co-infections. Childhood TB is a neglected aspect and a significant health problem in epidemic areas. It constitutes more than 20% of TB incidence. Pediatric TB exists in the shadow of adult TB. The clinicians concentrate on pulmonary manifestation of TB, whereas it is a major problem in both pulmonary and extra-pulmonary infections. The rate of infection with this disease is mostly associated with poverty, social disruption and human immunodeficiency virus (HIV) infection. The diagnosis of extra-pulmonary TB (EPTB) is more difficult than pulmonary TB (PTB). Delayed diagnosis and executive treatment contribute to increase in the mortality rate in endemic areas. This article provides the evidence-based simple and safe screening method, indicating rapid, highly sensitive and specific diagnostic tests for pulmonary and EPTB in children. The most important aspect of treatment is the correct course of anti-tubercular drugs. This review serves the purpose of quick reference for microbiologists, epidemiologists, academicians, students and researchers. It provides guidance regarding early diagnosis and treatment accuracy of pediatric TB.

Abstract
Cystic lesions of the mediastinum may be congenital or acquired. The differential diagnosis depends on their location in the mediastinum. Cysts in the posterior mediastinum are generally developmental cysts and are neurogenic or of foregut origin. We report the case of a 14-year-old boy, who presented with dry cough and progressively increasing breathlessness, and was found to have a cystic lesion in the posterior mediastinum. Fine needle aspiration from the cyst helped make a diagnosis of tuberculosis.

Abstract
Tuberculosis is a major public health problem in developing countries. Hand and wrist is a rare localization for extra-pulmonary tuberculosis, a pseudotumoral form of soft tissue tuberculosis of the wrist is exceptional. We report the case of a 45-year-old male presenting with a painful swelling of the dorsal aspect of the right wrist evolving for six months. Clinical study was evoking a ganglion cyst of the wrist. Intraoperatively a pseudotumoral mass with rice bodies was found, suggesting tuberculous tenosynovitis. The histopathological study revealed caseating giant cell granulomas with epithelioid cells. Cultures on Löwenstein-Jensen medium detected Mycobacterium tuberculosis. Synovectomy with removal of all the rice bodies followed by anti-tuberculous chemotherapy provided uneventful recovery.

Abstract
Background Lung cancer is the most lethal type of cancer in the world. Several benign lung diseases may mimic lung carcinoma in its clinical and radiological presentation, which makes the differential diagnosis for granulomatous diseases more relevant in endemic regions like Brazil. This study was designed to describe the prevalence and the diagnostic work-up of benign diseases that mimic primary lung cancer in patients hospitalized at a university hospital from south of Brazil. Methods This was a transversal study, which evaluated the medical records of 1,056 patients hospitalized for lung cancer treatment from September 2003 to September 2013 at University Hospital of Santa Maria. Results Eight hundred and four patients underwent invasive procedures for suspected primary lung carcinoma. Primary lung cancer was confirmed in 77.4% of the patients. Benign disease was confirmed in 8% of all patients. Tuberculosis (n=14) and paracoccidioidomycosis (n=9) were the most frequent infectious diseases. The diagnosis of benign diseases was obtained by flexible bronchoscopy in 55.6% of the cases and by thoracotomy in 33.4%. Conclusion Infectious diseases are the most frequent benign diseases mimicking lung cancer at their initial presentation. Many of these cases could be diagnosed by minimally invasive procedures such as flexible bronchoscopy. Benign diseases should be included in the differential diagnosis during the investigation for primary lung cancer in order to avoid higher cost procedures and mortality.

Abstract
Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of unknown etiology that can mimic malignancy on clinic-radiological and pathological examination. We describe a rare case of ileocecal intussusception from clinically suspected malignancy of the right colon where the patient underwent right hemicolectomy. Histopathology of the resected specimen confirmed IPT of the colon. This patient was observed to have abnormally elevated total leukocyte count and platelets before and after surgery. In an adult with intussusception associated with an abdominal mass, the possibility of IPT of the colon should be considered. Considering the abnormally high total leukocyte and platelet counts and colonic IPT, it is necessary to prevent postoperative adverse effects due to these changes. Although IPT of the colon is usually a benign process, controversy regarding its management still exists. We consider hemicolectomy as a safe treatment approach for colonic IPT and review the existing literature.

Abstract
Tuberculosis and cryptococcosis are infectious diseases that can result in the formation of single or multiple nodules in immunocompetent patients. Exposure to silica is known to raise the risk of infection with Mycobacterium tuberculosis. We report the case of an elderly man with no history of opportunistic infections and no clinical evidence of immunodeficiency but with a six-month history of dry cough and nocturnal wheezing. A chest X-ray revealed a mass measuring 5.0 × 3.5 cm in the right upper lobe. The diagnostic approach of the mass revealed tuberculosis. The histopathological analysis of the surrounding parenchyma reveled silicosis and cryptococcosis. Cryptococcosis was also found in masses identified in the mediastinal lymph nodes. The surgical approach was indicated because of the degree of pleuropulmonary involvement, the inconclusive results obtained with the invasive and noninvasive methods applied, and the possibility of malignancy. This case illustrates the difficulty inherent to the assessment of infectious or inflammatory pulmonary pseudotumors, the differential diagnosis of which occasionally requires a radical surgical approach. Despite the presence of respiratory symptoms for six months, the first chest X-ray was performed only at the end of that period. We discuss the possible pathogenic mechanisms that might have led to the combination of three types of granulomatous lesions in the same lobe, and we emphasize the need for greater awareness of atypical presentations of pulmonary tuberculosis.

Abstract
Background Tuberculous is the leading cause of death worldwide with a large number of deaths occurring in developing countries. Tuberculous lymphadenitis is among the most common presentations of extra pulmonary tuberculous. This study attempts to determine the magnitude of tuberculous lymphadenitis from patients with lymph node aspirate in Gondar University Hospital, Northwest Ethiopia. Methods Retrospective study was conducted. Data were collected from registration book of Gondar university Hospital pathology laboratory after checking the completeness of patient’s necessary information like age, sex and fine needle aspiration cytology results. Data were entered and analyzed using SPSS version 16 statistical package. Chi-square test was done to determine associations. Result A total of 3,440 lymph node aspirates were examined using fine needle aspiration cytology. Of these, 2,392 (69.5%) cases were found to have tuberculous lymphadenitis. Male 1647(47.9%) to female 1793(52.1%) ratio of all study subjects were 0.9:1. Females (54.1%) were more affected than males (45.9%). Age, sex and site of aspiration were found to be statistically associated with tuberculous lymphadenitis (p-value < 0.001). The age group of 15–24 years had the highest prevalence of tuberculous lymphadenitis followed by those of 25–34 years old. The most affected sites were cervical lymph nodes (47.5%) followed by auxiliary (19.4%) and submandibular (12.9%) lymph node regions. None of the records documented the HIV status of subjects. Conclusion The prevalence of tuberculous from lymph node aspirate was found to be higher involving the frequently affected site of cervical lymph node. The HIV status of patients with all forms of tuberculous should have to be checked and documented. Further prospective and advanced studies are recommended to determine the specific etiologic agents and contributing factors.

Abstract
BACKGROUND Systematic reviews are increasingly informing policies in tuberculosis (TB) care and control. They may also be a source of questions for future research. As part of the process of developing the International Roadmap for TB Research, we did a systematic review of published systematic reviews on TB, to identify research priorities that are most frequently suggested in reviews. METHODOLOGY/PRINCIPAL FINDINGS We searched EMBASE, MEDLINE, Web of Science, and the Cochrane Library for systematic reviews and meta-analyses on any aspect of TB published between 2005 and 2010. One reviewer extracted data and a second reviewer independently extracted data from a random subset of included studies. In total, 137 systematic reviews, with 141 research questions, were included in this review. We used the UK Health Research Classification System (HRCS) to help us classify the research questions and priorities. The three most common research topics were in the area of detection, screening and diagnosis of TB (32.6%), development and evaluation of treatments and therapeutic interventions (23.4%), and TB aetiology and risk factors (19.9%). The research priorities determined were mainly focused on the discovery and evaluation of bacteriological TB tests and drug-resistant TB tests and immunological tests. Other important topics of future research were genetic susceptibility linked to TB and disease determinants attributed to HIV/TB. Evaluation of drug treatments for TB, drug-resistant TB and HIV/TB were also frequently proposed research topics. CONCLUSIONS Systematic reviews are a good source of key research priorities. Findings from our survey have informed the development of the International Roadmap for TB Research by the TB Research Movement.

Abstract
Background. Tuberculosis is the commonest infectious disease in the developing world. Many diagnostic tests are devised for its detection including direct smear examination. This study was designed to determine the frequency of cases positive for AFB and positive for fungus in patients diagnosed to have granulomatous inflammation on Fine Needle Aspiration Cytology using special stains. Materials and Methods. A descriptive cross-sectional survey was done on 100 cases of granulomatous inflammation consistent with tuberculosis diagnosed on fine needle aspiration cytology at the Department of Pathology, King Edward Medical University, Lahore. After reporting granulomatous inflammation on Hematoxylin & Eosin staining of aspirates from FNAC, some unstained slides were subjected to special stains, like ZN, GMS, and PAS. Cases positive for AFB on ZN stain and fungus on GMS/PAS were noted down along with their frequency and percentages. Results. Forty-four cases (44%) of AFB positive smears were reported in granulomatous inflammation while only 5% cases of fungus were reported down. Cervical lymph nodes were the most commonly involved site (87%), and females were affected more (62%) than males. Most cases of AFB-positive smears were associated with caseation necrosis (93%). Conclusion. Special stains should be done on all granulomatous inflammation cases seen on FNAC for confirmation of TB and ruling out other infectious causes.

Abstract
Pseudotumour is a rare presentation of bronchopulmonary tuberculosis, occurring in immunocompetent patients, which simulates lung cancer and may thus cause diagnostic difficulty. To assess the frequency and clinical features of tuberculous pseudotumour in immunocompetent patients, we analyzed all cases of pulmonary tuberculosis hospitalized in our department. Tuberculous pseudotumour was defined by the presence of a bronchial or pulmonary lesion suggestive of lung cancer. Over a period of 11 years, 12 cases of tuberculous pseudotumour were collected among 341 cases of pulmonary tuberculosis (3.5%). Mean age was 45 years. All patients were smokers. Symptoms were not specific and were dominated by cough and chest pain. Radiological investigations showed consolidation in five cases and a mass lesion in five cases. Fibreoptic bronchoscopy visualized a tumour in four cases and stenosing bronchial wall infiltration in one case. Mean delay to diagnosis was 47 days. The confirmation of tuberculosis was bacteriologic in only three cases but histological in the others (four bronchial biopsies, two transbronchial biopsies, one pleural biopsy, four surgical specimen). The positive diagnosis of tuberculous pseudotumour is difficult because the clinical and radiological presentation may closely mimic lung cancer, especially as the cases are usually smear negative, leading to a very late diagnosis.
