pulmonary bullous

OBJECTIVE: Pulmonary placental transmogrification (PT) is a benign lesion curable by resection, represented by an unusual peculiar morphological variation including placentoid bullous change in the pulmonary hamartoma. In this retrospective study, we aimed to examine the histopathological features of pulmonary hamartomas in lung, to evaluate the different histological components, especially PT, and to investigate importance of PT pattern and its relationship with other clinicopathological features...

BACKGROUND: Giant bullae (GB) are space occupying lesions associated with chronic respiratory symptoms. The aim of this study is to evaluate outcome of intra-cavitary tube drainage procedures (ITDP) in terms of clinical and radiological benefits. METHODS: A prospective study was conducted in The Department of Thoracic Surgery, Jinnah Postgraduate Medical Center, Karachi, from February 2021 to April 2022 after ethical approval. Patients above 12 years, with poor reserve and GB underwent clinical, radiological and laboratory assessment before and after ITDPs to document various studied parameters...

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first isolated in Wuhan, China, is currently a pandemic. At the beginning of the pandemic, pulmonary issues were the most discussed and studied. However, now 3 years later, the role of the dermatologist has become increasingly central. Often the diversity in the presentation of these manifestations has made it difficult for the dermatologist to recognize them. In addition to the common symptoms involving fever, cough, dyspnea, and hypogeusia/hyposmia that have been widely discussed in the literature, much attention has been paid to dermatologic manifestations in the past year...

Pulmonary bullae usually grow slowly and have thin walls. However, we have observed 2 cases of abrupt bulla formation immediately after lobectomy and during surgery. The pathologic findings of what can be called visceral pleural detachment are quite distinctive: these bullae had a broad base connected to the lung, and their walls were thick, including the full extent of visceral pleural and peripheral alveolar tissues, which suggests that the visceral pleura were detached from the distal alveoli. High transpleural pressure might be the key factor in the pathogenesis of this type of bulla, unlike previously known types of bullous lung disease...

Pulmonary sarcoidosis may occasionally present with large bullae, but the clinical implications of this finding remain unclear. We herein report the complete clinical course of a case of pulmonary bullous sarcoidosis. Chest computed tomography initially showed subpleural and peribronchovascular lung opacities, and bullae spontaneously developed in adjacent less-affected regions, probably via a retraction mechanism. Bullae progression was refractory to corticosteroid treatment and associated with deterioration of respiratory symptoms...

BACKGROUND Vanishing lung syndrome (VLS), also known as idiopathic giant bullous emphysema, is a rare manifestation of chronic obstructive pulmonary disease (COPD) and usually occurs in middle-aged smokers. This report presents a 58-year-old female smoker with COPD and VLS who presented with spontaneous pneumothorax. The pneumothorax was managed with a chest tube and was later complicated by massive subcutaneous emphysema. CASE REPORT A 58-year-old woman with a past medical history of long-term smoking and COPD presented with worsening shortness of breath...

Pleuropulmonary synovial sarcoma (PPSS) is a primary malignancy of the lung, uncommon in pediatrics (prevalence: 0.1-0.5%) that predominantly affects adolescents and young adults. Overall survival has been reported to be close to 30% at 5 years. Here we report the case of a previously healthy 12-year-old male patient who presented with cough, chest pain, and dyspnea of sudden onset as initial manifestation of left pneumothorax, which persisted after 4 days and required surgical resection of pulmonary bullous lesion...

Unconventional inhaled therapy as a treatment for respiratory diseases became very common during the 19th century. Here, we present the case of a 52-year-old patient who smoked Datura stramonium cigarettes, tobacco cigarettes, and cannabis, with only an early diagnosis of asthma. The patient was admitted to our hospital with acute respiratory syndrome, characterized by worsening dyspnea, cough, and an acute episode of dyspnea and chest tightness. The combined chronic use of both D. stramonium cigarettes and cannabis masks the progression of chronic obstructive lung damage due to tobacco cigarette smoking because of the lack of clinical signs and symptoms...

Stevens-Johnson syndrome and Lyell syndrome are severe bullous drug reactions that can be life-threatening. The aim of this study is to describe the epidemiological, etiological, clinical, therapeutic and evolutionary data of patients hospitalized in our Dermatology Department. This is a retrospective descriptive study over a period of 10 years. All records of patients admitted to the Dermatology Department for these cutaneous adverse drug reactions were included. A total of 30 patients were recorded, with a male predominance...

INTRODUCTION: Gestational trophoblastic neoplasia (GTN) is a group of malignant neoplasms that arise from abnormal proliferation of trophoblastic tissue. The metastatic spread rate is depended on the histopathological type, with pulmonary metastases being the most common (80%) in patients with metastases. Pneumothorax as a primary manifestation is extremely rare. We hereby discuss a unique case of spontaneous hemi-pneumothorax due to metastatic GTN in a 30-weeks pregnant woman. CASE PRESENTATION: A 25-year-old woman - G2 P0 A1 - was admitted to our maternal intensive care department with atypical respiratory symptoms...

BACKGROUND: Placental transmogrification of the lung (PTL) is a clinical spectrum varying from asymptomatic to severe pulmonary impairment; such as recurrent pneumothorax, bronchopneumonia, respiratory distress syndrome and chronic obstructive airway disease. PTL usually presents as a bullous lesion, and rarely can appear in nodule or cyst formation on chest imaging. PTL with giant bullous emphysema has a male preference, is more commonly unilateral and mostly affects one lobe, but can rarely involve more than one lobe...

BACKGROUND: Idiopathic Giant Bullous Emphysema (or Vanishing Lung Syndrome) is a rare condition which is usually associated with male gender, active smoking and underlying emphysematous disease. We present an unusual case of a giant bulla occurring in the absence of these risk factors. CASE PRESENTATION: A 54-year-old woman presented to the respiratory outpatient clinic with gradually worsening left sided chest discomfort, which was most marked during a recent flight...

BACKGROUND: Fluorescence imaging using indocyanine green in thoracic and esophageal surgery is gaining popularity because of the potential to facilitate surgical planning, to stage disease, and to reduce postoperative complications. To optimize use of fluorescence imaging in thoracic and esophageal surgery, an expert panel sought to establish a set of recommendations at a consensus meeting. METHODS: The panel included 12 experts in thoracic and upper gastrointestinal surgery from Asia-Pacific countries...

Critically ill COVID-19 patients have to undergo positive pressure ventilation, a non-physiological and invasive intervention that can be lifesaving in severe ARDS. Similar to any other intervention, it has its pros and cons. Despite following Lung Protective Ventilation (LPV), some of the complications are frequently reported in these critically ill patients and significantly impact overall mortality. The complications related to invasive mechanical ventilation (IMV) in critically ill COVID-19 patients can be broadly divided into pulmonary and non-pulmonary...

RATIONALE: Anlotinib is an oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor, and has been approved for the treatment of patients with advanced nonsmall cell lung cancer who had received at least 2 previous chemotherapy and epidermal growth factor receptor/anaplastic lymphoma kinase targeted therapy regimens. Pneumothorax is a rare adverse reaction of this drug. Here, we present a case of pneumothorax following anlotinib treatment in a patient with lung cancer...

Although bullous pemphigoid (BP) and atopic dermatitis (AD) share pathogenic mechanisms, their relationship remains controversial. Therefore, we conducted a population-based case-control study to investigate the association between BP and AD in Taiwan. Based on the Taiwan National Health Insurance Research Database, 9344 patients with BP and 18,688 age- and sex-matched controls were enrolled between 2000 and 2013. Furthermore, the study included 7,196 BP patients and 14,392 controls, matched for age, sex, and propensity score of comorbidities, with a case to controls ratio of 1:2...

A 57-year-old man who had recurrent respiratory infections due to tobacco use and severe chronic obstructive pulmonary disease (COPD) was evaluated as an outpatient to discern the etiology. He was followed with a chest X-ray and a chest computed tomography (CT) scan that displayed a left upper lobe cavitary lung abnormality. The lesion was further evaluated with a CT-guided biopsy, and it was identified as a lung abscess. A tissue culture isolated Propionibacterium acnes . We present a rare case of a common skin commensal, P...

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is a serious complication occurring in immunocompromised patients, who often show multiple nodular lesions with or without cavitation. Due to high mortality and poor prognosis, the earlier detection and initiation of treatment are needed, while the definitive diagnosis is often difficult to make in clinical settings. Septic pulmonary embolism (SPE) is a complication that occurs in patients with bloodstream infections (e.g., infectious endocarditis)...

Linear IgA bullous dermatosis (LABD) is an auto-immune disease affecting young children and adults, characterized by the linear deposition of IgA at the basement membrane zone with resultant complement activation and a cascade of immune reactions. There is a loss of adhesion at the dermo-epidermal junction and subsequent blister formation. It is a rare disease that has a good prognosis with adequate therapy. However, the underlying depressed immunity associated with the disease may expose them to such infections as tuberculosis...
