Extraintestinal respiratory manifestations in inflammatory bowel disease (IBD) are rare. We present a case of bronchiolitis obliterans organizing pneumonia (BOOP) in a patient with Crohn s disease, with clinical remission with no drug therapy.

Cryptogenic organizing pneumonia (COP) generally responds well to corticosteroids with a favorable outcome. Rare cases of organizing pneumonia are rapidly progressive. Yousem et al. studied pathologic predictors of idiopathic bronchiolitis obliterans organizing pneumonia/COP with an unfavorable prognosis. Beardsley and Rassl proposed the name fibrosing organizing pneumonia (FOP). A 74-year-old ...

Carbamazepine-induced lupus is uncommon; its frequency is less than 0.001% of the cases of lupus treated. Herein we describe a 52-year-old woman who had development of facial erythema, arthralgia, dyspnea, and multiple pulmonary rounded masses and nodules while she was taking carbamazepine for epilepsy. Pulmonary histologic examination showed bronchiolitis obliterans organizing pneumonia. Antin...

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 ...

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...

Bronchiolar abnormalities are relatively common and occur in a variety of clinical settings. Various histopathologic patterns of bronchiolar injury have been described and have led to confusing nomenclature with redundant and overlapping terms. Some histopathologic patterns of bronchiolar disease may be relatively unique to a specific clinical context but others are nonspecific with respect to ...

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...
