a 46-year-old woman presented with progressive dyspnea and cough. she was a known case of chronic hepatitis c (hcv) treated with pegylated (peg)-interferon. complete pulmonary studies and biopsy were compatible with bronchiolitis oblitrans with organizing pneumonia (boop) secondary to peg-interferon. she discontinued peg-interferon and was given a short course of steroids, after which the condi...

The disease concept of idiopathic BOOP has emerged from a study of many open lung biopsy cases of diffuse infiltrative lung disease. The histopathologic features of idiopathic BOOP have several components: bronchiolitis obliterans, organizing pneumonia, accumulation of foamy cells in the peripheral air spaces, and interstitial infiltration of mononuclear cells. These pathologic findings are non...

Hilar or mediastinal lymphadenopathy is not included in the wide spectrum of radiologic findings associated with bronchiolitis obliterans-organizing pneumonia (BOOP). We present a patient who presented with extensive hilar and mediastinal lymphadenopathy. We suspected a diagnosis of sarcoidosis. The patient was diagnosed with idiopathic BOOP. This is the first case demonstrating that BOOP, now ...

Bronchiolitis obliterans (BO) and bronchiolitis obliterans organizing pneumonia (BOOP) are late-onset non-infectious pulmonary complications (LONIPCs) following allogeneic hematopoietic stem cell transplantation (HSCT). In the present study 10 of 197 conventionally prepared stem cell recipients developed BOOP after 365 days and 6 patients developed BO 333 days post-transplant. No BOOP or BO was...

We treated a 51-year-old woman who had rapidly progressive respiratory distress with an interstitial shadow on chest roentgenogram. Pathologically, open lung biopsy specimens showed an acutely changed lesion such as interstitial inflammatory thickening, polypoid intraluminal organizing exudates, and also honeycombing which was not recognized on chest computed tomogram. These findings were consi...

A 70 year old man presented with symptoms and laboratory findings suggestive of chlamydial pneumonia. Despite adequate antibiotic therapy, his condition did not improve and transbronchial biopsies disclosed a typical feature of bronchiolitis obliterans organizing pneumonia (BOOP). After initiation of corticosteroid therapy, there were marked clinical and radiographic improvements. This report d...

A patient with bronchiolitis obliterans organizing pneumonia (BOOP) associated with acute Mycoplasma pneumoniae infection is described. Although mycoplasmas have occasionally been associated with bronchiolitis obliterans, to the best of our knowledge, this is the first well-documented case of BOOP associated with M. pneumoniae infection. The diagnosis of BOOP was made by open-lung biopsy after ...

Bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathological entity with well-defined diagnostic criteria, the aetiology of which is generally unknown. Among the adverse pulmonary effects of the drug amiodarone, BOOP is the least commonly reported in the literature. In this article we describe a case of amiodarone-induced BOOP.
