Domestically acquired particulate lung disease (DAPLD) or hut lung is a pneumoconiosis due to exposure from smoke from biomass fuel used in cooking in an enclosed space.
Typically women who present with symptoms of a pneumoconiosis without the history of occupational exposure 2,3. The estimated prevalence is up to 20% in at-risk women 3. It typically occurs in developing countries 2.
Plain radiograph and CT
Findings are non-specific 1,2:
- upper zone predominant pulmonary nodules: diffuse fine nodules through to large irregular nodule
- massive pulmonary fibrosis-like change in advanced cases
Other pneumoconioses should be considered, especially silicosis 1.
