Castleman disease-associated diffuse parenchymal lung disease

چکیده
Intrathoracic involvement is common in Castleman disease (CD), but CD-associated diffuse parenchymal lung disease (DPLD) is rare and not well-reported.We conducted a retrospective analysis of 262 CD patients with a definite pathological diagnosis who were hospitalized between 1999 and 2015.Twenty-two CD patients had DPLD based on chest computed tomography (CT) scans. Among them, 9 were male and 13 were female, with a mean age of 45.3 years. Coughing (72.7%), fever (68.2%), and dyspnea (59.1%) were the common clinical manifestations. In high-resolution CT, obvious lymphadenopathy (81.8%) was the most frequent, followed by multiple nodules of different sizes (72.7%), cysts (59.1%), and patches of ground-glass opacity (54.5%). Six patients had lymphocytic interstitial pneumonia (LIP)-like CT images. Superficial lymph node biopsies (63.6%), video-assisted thoracic surgery lung biopsies (27.3%), CT-guided percutaneous lung biopsies (9.1%), and endoscopic lymph node biopsies (9.1%) were performed to make final diagnoses. The hyaline vascular variant (27.3%), the plasma cell variant (63.6%), and the mixed variant (9.1%) were the pathological subtypes. All but 2 were prescribed chemotherapy, and none was administered anti-interleukin-6 therapy. Among them, 14 patients improved, 3 died, 2 were stable, 2 were refractory, and 1 was lost to follow-up.Chinese CD-associated DPLD might be more prevalent in middle-aged female patients, with most cases being the plasma cell variant. Although a LIP-like pattern was reported, only one-quarter of the patients showed LIP-like CT images. Multiple nodules (especially solid nodules), cysts, and patchy areas were the common pulmonary radiological findings. More than half of the patients improved after chemotherapy. A well-designed prospective study should be performed to confirm these results.

The technique of transbronchial lung biopsy (TBLB) has expanded the diagnostic yield of bronchoscopy . In this article we are presenting 54 patients with diffuse pulmonary parenchymal involvement who underwent this procedure during six years between June 1980 and December 1989. The diagnostic yield of this technique in diffuse pulmonary parenchymal disease is great and was 66 percent exclu...

Background: Transbronchial lung biopsy (TBLB) is an attractive alternative to open lung biopsy as an initial diagnostic procedure for patients with diffuse parenchymal disease or localized densities beyond direct endoscopic vision. TBLB can be carried out safely without fluoroscopy in patients with diffuse lung disease. Since in our bronchoscopic department fluoroscopy is not available, we plan...
