To know the background and pathophysiology of the Hut lung disease. To learn the different clinical presentations of patients with Hut lung disease. To recognize different imaging patterns of Hut lung disease on HRCT chest. To be able to recognize the different bronchoscopic findings in patients with Hut lung disease.

Biomass is used as a major fuel source by more than 50% of the world’s rural population.1 It includes materials derived from animal dung, twigs, grass, crop wastes, wood, and charcoal. More than half of the world’s population uses biomass as a major source of energy for cooking and heating.2 This fuel source is inefficient, requiring fires to be kept going for many hours a day, exposing women and children exposed to years of daily smoke leading to chronic obstructive pulmonary disease.3 Patients typically present...

Jinnah Postgraduate Medical Centre is a tertiary care center where we receive a large number of referrals from the pulmonary clinic for evaluation of respiratory symptoms.We wish to share a series of 33 cases of Hut lung disease, in Pakistani rural population with a long-term biomass exposure in poorly ventilated environments. To our knowledge, this is the first reported series from Pakistan describing the HRCT chest findings in such a large number of patients of Hut lung disease. In our series, majority of the patients...

Hut lung represent the non-infectious, nonmalignant respiratory manifestations of chronic, high level exposures to biomass smoke. The rural population of underdeveloped and developing countries continue to be exposed to high levels of biomass smoke in occupatinal and demestic environments. More research needs to be done to better characterize disease mechanism, progression, and interventions for prevention and treatment. As residents of lesser developed countries continue to be exposed to high levels of biomass smoke at home or at work and continue to immigrate to developed countries,...
