Bottom Line: The etiology of the disease is unclear, although some cases have been associated as a complication after bone marrow transplantation, lung transplantation (LT), chemotherapy, and recurrent respiratory infections.That is why better awareness with the clinical and radiologic features can help optimal management by the multidisciplinary team.We present the first reported cases in Spain.

ABSTRACT
Pleuroparenchymal fibroelastosis (PPFE) is a rare entity that has been recently included in the official American Thoracic Society/European Respiratory Society (ATS/ERS) statement in 2013 as a group of rare idiopathic interstitial pneumonias (IIPs). PPFE is characterized by pleural and subpleural parenchymal thickening due to elastic fiber proliferation, mainly in the upper lobes. The etiology of the disease is unclear, although some cases have been associated as a complication after bone marrow transplantation, lung transplantation (LT), chemotherapy, and recurrent respiratory infections. The patients usually report progressive dyspnea and dry cough and are predisposed to develop spontaneous or iatrogenic pneumothoraces after surgical lung biopsy (SLB) for its diagnosis. That is why better awareness with the clinical and radiologic features can help optimal management by the multidisciplinary team. Novel invasive techniques such as cryobiopsy may become useful tools in these patients as it could spare SLB. We present the first reported cases in Spain.

Mentions: After 3 months, the patient developed progressive clinical deterioration with hypoxemia and oxygen desaturation during a 6-minute walk test (6 MWT) with minimal saturation of 81%. Therefore, he was treated with supplemental oxygen and oral corticosteroids (1 mg/kg/day with progressive dose reduction). SLB was performed a month after initiating the treatment with right apical pneumothorax as a complication. The biopsy revealed marked subpleural thickening and homogenous and extensive areas of fibrosis. Dense elastic fibers were seen in the subpleural area and adjacent parenchyma on elastic stain (Figure 2). After having made the diagnosis by SLB, it was decided to reexamine the histological sample from the cryobiopsy and make the Weigert Van Gieson stain, observing the elastic fibers herein (Figure 3).
