Breast carcinoma is one of the tumors that frequently metastasize to the liver. Extramedullary hematopoiesis (EMH) usually occurs due to insufficient medullary hematopoiesis. In this case report, we present a female patient with sinusoidal breast carcinoma metastasis and extramedullary hematopoiesis in liver biopsy. A 63-year-old female patient with history of breast carcinoma was admitted to our center with respiratory distress. Pleural effusion was detected and thoracentesis was planned. Treatment was given after detection of non-mycobacterial tuberculosis bacillus in the thoracentesis fluid. Antibiotherapy was terminated due to elevation of liver enzymes and bilirubin. The patient's clinical status was evaluated and treatment was re-initiated. The patient did not have any mass lesion in the liver. Tru-cut biopsy was performed to evaluate a possible tuberculosis involvement in the liver. The diagnosis of metastatic breast carcinoma located in the sinusoidal area and cholestatic liver with extramedullary hematopoiesis foci was given using the histomorphological, immunohistochemical and histochemical findings. Radiological evaluation has an important role in staging of malignancies. However, it should be kept in mind that hepatic metastases may present without formation of a mass lesion, and unexpected laboratory results of cases without abnormal radiological features should raise the suspicion of a metastasis. Such materials should be evaluated in detail by making multiple serial sections in the pathology laboratory. Rare metastatic tumor growth patterns not causing a mass lesion such as sinusoidal or portal pattern, should also be kept in mind.

Tuberculous pleuritis (TP) is one of the most common extra-pulmonary tuberculosis form. Because of tuberculous pleurisy is hard to diagnose due to slow course of disease and lack of specificity in symptoms and diagnostic methods. In that reason, we need multidisciplinary approach and efficient biomarkers. Acid-fast bacilli (AFB) staining, cultures and pathophysiological biopsy finding from the majority of patients are positive only in less than 10%. Löwenstein culture results need time about 6-8 weeks what delays diagnosis. Adenosine deaminase (ADA) is biomarker with high sensitivity and specificity (more than 90%) and considered as gold standard of biomarkers in the diagnosis of TP. It is very hard to distinguish malignant from TP with lymphocyte predomination, but in patient with malignant pleural effusion the level of ADA is decreased, opposite from TP. ADA in pleural punctate is a fast, simple, efficient and economical way for clarification the etiology of the pleural effusion as tuberculous pleurisy. Also, many studies have proved the role of ADA in the response to treatment for tuberculosis at follow up period.

is a gram-negative obligate anaerobe mainly associated with infections of odontogenic origin. Non-oral monomicrobial infection by these obligate anaerobic bacteria is rare. Only a few cases of monomicrobial non-oral infections by have been reported in the literature. We are reporting a case of unilateral complicated pleural empyema in a patient with bronchial asthma infected by . Pleural fluid aerobic culture and blood culture reports were sterile. No acid-fast bacilli were detected by Acid Fast Bacilli (AFB) staining, and cartridge-based nucleic acid assay test (CBNAAT) reports were negative for . The isolate, was found susceptible to Metronidazole (MIC = 3 μg/ml) and resistant to Clindamycin (MIC = 256 μg/ml). In view of rising trends of antimicrobial resistance among anaerobes, it is recommended to perform anaerobic culture and sensitivity testing in clinically suspected cases of pleuropulmonary infection for appropriate diagnosis and optimal patient management. Clindamycin should be used with caution for empiric treatment.

BACKGROUND
There are many methods of evaluating diaphragmatic function, including trans-diaphragmatic pressure measurements, which are considered the key rule of diagnosis. We studied the clinical usefulness of chest ultrasonography in evaluating stable chronic obstructive pulmonary disease (COPD) patients and those in exacerbation, focusing on diaphragmatic measurements and their correlation with spirometry and other clinical parameters.
METHODS
In a prospective case-control study, we enrolled 100 COPD patients divided into 40 stable COPD patients and 60 patients with exacerbation. The analysis included 20 age-matched controls. In addition to the clinical assessment of the study population, radiological evaluation included chest radiographs and chest computed tomography. Transthoracic ultrasonography (TUS) was performed for all included subjects.
RESULTS
Multiple A lines (more than 3) were more frequent in COPD exacerbation than in stable patients, as was the case for B-lines. TUS significantly showed high specificity, negative predictive value, positive predictive value, and accuracy in detecting pleural effusion, consolidation, pneumothorax, and lung mass. Diaphragmatic measurements were significantly lower among stable COPD subjects than healthy controls. Diaphragmatic thickness and excursion displayed a significant negative correlation with body mass index and the dyspnea scale, and a positive correlation with spirometry measures. Patients in Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D showed lower diaphragmatic measurements (thickness and excursion).
CONCLUSION
The TUS of COPD patients both in stable and exacerbated conditions and the assessment of diaphragm excursion and thickness by TUS in COPD patients and their correlations to disease-related factors proved informative and paved the way for the better management of COPD patients.

BACKGROUND
Symptoms of inflammatory myofibroblastic tumor (IMT) are atypical, and histopathological misdiagnosis of IMT is still inevitable. Here we present a pediatric case that an eight-year-old boy with recurrent fever for fifteen months, received anti-tuberculosis therapy for five months and was ultimately confirmed to be IMT.
CASE PRESENTATION
An eight-year-old boy experienced a recurrent fever for fifteen months, accompanied by cough, vomiting, meteorism, night sweating, and emaciation. Thoracoabdominal computer tomography revealed multiple enlarged lymph nodes in the thorax, abdomen, and axilla, as well as minimal bilateral pleural effusion. Histopathological examinations of the intestines and greater omentum implied fibrous tissue hyperplasia along with eosinophil and lymphocyte infiltration. The patient was initially misdiagnosed with tuberculosis, and symptoms were relieved partially following anti-tuberculosis treatment. However, after four months, the symptoms aggravated again and a subsequent histopathological analysis of a second sample from the greater omentum revealed the presence of IMT. Eventually, after surgical resection of the lesions and chemotherapy, the clinical symptoms in the child gradually alleviated.
CONCLUSIONS
The clinical course of IMT is variable, and pediatricians should pay attention to differentiating IMT from tuberculosis.

INTRODUCTION
Empyema necessitans (EN) is an uncommon condition where an intrathoracic empyema extends into surrounding extra-thoracic tissues. This case report presents a rare instance of tuberculous EN in an immunocompetent individual.
PRESENTATION OF CASE
We present a case of a healthy young male with complaints of weight loss and a chest wall swelling, initially treated as a subcutaneous abscess. He had a history of TB contact and initial laboratory tests showed elevated CRP and ESR, with no bacterial growth on initial culture from FNAC sample. Subsequent imaging revealed the presence of pleural empyema. Following surgical intervention, a connection between fluid collection outside the thoracic wall and the pleural cavity was identified. Diagnosis of tuberculous EN was made on results of second culture of the fluid collection. The patient was further treated with anti-tuberculous treatment.
DISCUSSION
EN, rare extrapulmonary complication of tuberculosis, is challenging to diagnose due to nonspecific symptoms and paucibacillary nature of extrapulmonary TB. Imaging plays a crucial role in diagnosis. A multidisciplinary approach involving surgery and anti-tuberculous treatment is effective in managing EN.
CONCLUSION
This case underscores the scarcity of EN occurrences and emphasizes the potential for latent TB to surface as atypical complications. Accurate diagnosis requires a combination of clinical insight, imaging, and laboratory tests. EN should be considered in individuals with chest wall masses, particularly in TB endemic areas, and those with a history of TB contact. Treatment involves surgical intervention and anti-tuberculous therapy.

Utilization of intraoperative indocyanine green fluorescence imaging to identify vascular anatomy in severe pleural adhesions in uniportal video-assisted thoracoscopic surgery: a case report.
BACKGROUND
Extensive and dense pleural adhesion is a serious challenge in video-assisted thoracoscopic surgery (VATS), in which identification of vessels and their anatomical spaces is difficult. Once critical vessel is damaged while dissecting adhesion in VATS, leading to fatal hemorrhage, the surgeon will have to switch to thoracotomy. This is the first report of a case in which intraoperative indocyanine green (ICG) fluorescence imaging was used to identify critical vessels in severe pleural adhesions in uniportal VATS.
CASE DESCRIPTION
The patient (67-year-old male) with an 8-year history of tuberculosis and severe mixed ventilation dysfunction underwent a standardized wedge resection due to chest computed tomography (CT) scan that revealed a 2.6-cm nodule in the right upper lung. Intraoperatively, the superior vena cava and azygos vein were successfully identified and safely dissected using ICG fluorescence imaging in the presence of extensive and dense pleural adhesions. The chest drainage tube was removed on postoperative day (POD) 3, and patient was released from hospital on POD 5. The patient recovered well and no complication was observed in the follow-up.
CONCLUSIONS
The ICG fluorescence imaging is used to illustrate the vessels and help to dissect them safely, which is a feasible, visualizable, and user-friendly method in severe pleural adhesions in uniportal VATS.

BACKGROUND
Malignant pleural mesothelioma (MPM) is a rare disease with limited treatment and poor prognosis, and a precise and reliable means to predicting MPM remains lacking for clinical use.
METHODS
In the population-based cohort study, we collected clinical characteristics from the Surveillance, Epidemiology, and End Results (SEER) database. According to the time of diagnosis, the SEER data were divided into 2 cohorts: the training cohort (from 2010 to 2016) and the test cohort (from 2017 to 2019). The training cohort was used to train a deep learning-based predictive model derived from DeepSurv theory, which was validated by both the training and the test cohorts. All clinical characteristics were included and analyzed using Cox proportional risk regression or Kaplan-Meier curve to determine the risk factors and protective factors of MPM.
RESULTS
The survival model included 3,130 cases (2,208 in the training cohort and 922 in the test cohort). As for model's performance, the area under the receiver operating characteristics curve (AUC) was 0.7037 [95% confidence interval (CI): 0.7030-0.7045] in the training cohort and 0.7076 (95% CI: 0.7067-0.7086) in the test cohort. Older age; male sex, sarcomatoid mesothelioma; and T4, N2, and M1 stage tended to be the risk factors for survival. Meanwhile, epithelioid mesothelioma, surgery, radiotherapy, and chemotherapy tended to be the protective factors. The median overall survival (OS) of patients who underwent surgery combined with radiotherapy was the longest, followed by those who underwent a combination of surgery, radiotherapy, and chemotherapy.
CONCLUSIONS
Our deep learning-based model precisely could predict the survival of patients with MPM; moreover, multimode combination therapy might provide more meaningful survival benefits.

Common causes of haemorrhagic pleural effusions include malignancy (primary or metastatic), tuberculosis, pulmonary embolism, collagen vascular diseases, trauma and iatrogenic causes. Clinical history along with pathologic, microbiologic and biochemical evaluation of pleural fluid confirms the diagnosis in most cases. However, if there is recurrent haemorrhagic effusion without corroborative history or mass lesion in lung, or evidence of microorganisms, then we should think of uncommon causes. Catamenial haemothorax (CHt) is a rare cause of haemorrhagic pleural effusion, which recurs during each menstrual cycle. This is a manifestation of thoracic endometriosis syndrome (TES) caused by ectopic endometrial tissue in the thoracic cavity in women of child-bearing age. This extremely rare condition is difficult to diagnose, unless direct correlation with the menstrual cycle is established. TES consists of pleural forms such as catamenial pneumothorax, non-catamenial endometriosis-related pneumothorax and haemothorax; and parenchymal forms such as catamenial haemoptysis and lung nodules. Here we report a case of CHt in a 43-year-old female whose diagnosis was established by thoracoscopic pleural biopsy.
