Domestically acquired particulate lung disease

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. 

Epidemiology

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.

Radiographic features

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
• hyperinflation

Differential diagnosis

Other pneumoconioses should be considered, especially silicosis ¹.
