Rare Presentation

Organising pneumonia (OP) is an interstitial lung disease characterised by granulation tissues in alveoli and alveolar ducts. Typical imaging findings are migratory airspace opacities with peripheral or peribronchovascular distribution. Diffuse micronodular OP (MNOP) is a rare imaging manifestation, which has imaging differential diagnosis of endobronchial infection such as tuberculosis, hypersensitivity pneumonitis and respiratory bronchiolitis. Although clinical and ancillary radiological findings may aid in refining the differential diagnosis, histopathological assessment is frequently required for this rare presentation due to implications of treatment and prognosis. We report a case of MNOP and performed a review of the literature.

Lung Malignancies

An estimated 1 in 3,000 to 1 in 4,000 persons in the general population have a diagnosis of interstitial lung disease (ILD), and ILDs account for about 15% of all consultations for general pulmonologists. These diseases encompass a group of heterogeneous lung conditions characterized by diffuse involvement of the lung parenchyma and pulmonary interstitium. By convention, infections, pulmonary edema, lung malignancies, and emphysema are excluded, but they should be carefully considered as part of the differential diagnosis.

Risk Of Progression

Abstract SSc is a rare disease of unknown origin associated with multiple organ involvement. One of the major complications that drives the mortality of SSc patients is interstitial lung disease. The course of SSc-interstitial lung disease progression has a wide spectrum. Since the treatment is based on aggressive immunosuppression it should not be given to stable or non-progressing disease. The correct identification of disease with high risk of progression remains a challenge for early therapeutic intervention, and biomarkers remain urgently needed. In fact, eight categories of biomarkers have been identified and classified according to the different biological pathways involved. The purpose of this article is to describe the main biomarkers thought to be of interest with clinical value in the diagnosis and prognosis of SSc-interstitial lung disease.

Multidisciplinary Team Meeting

Our case series describes two siblings with complex fibrosing lung diseases. The first patient was initially given a diagnosis of sarcoidosis based on imaging and exclusion of alternative diagnoses. A number of years after diagnosis, he had rapid deterioration of his disease and following surgical lung biopsy, his lung fibrosis was re-classified as chronic hypersensitivity pneumonitis (cHP) with a usual interstitial pneumonia pattern. He subsequently underwent successful lung transplantation. The second patient presented with rapidly progressing exertional dyspnoea. His bloods, imaging, bronchoalveolar lavage and histology were discussed at our multidisciplinary team meeting. His histology was most in keeping with subacute on cHP with overlapping imaging features between the two siblings. He was treated accordingly but unfortunately succumbed to his illness shortly after diagnosis. These cases highlight the difficulties differentiating between the various interstitial lung disease (ILD) subtypes and the challenges in management while also increasing awareness of familial ILD.
