Acid sphingomyelinase deficiency (ASMD) is an ultra-rare, progressive, and often fatal LSD with an estimated prevalence of 1-in-50,000–250,000 individuals.

Reanalysis of the previously resected surgical specimens confirmed the presence of the <em>EGFR</em> S768I and L858R compound mutations in all samples, which suggests that S768I was not an acquired resistance mutation. Furthermore, immunohistochemical analysis revealed an increase in HER2 and HER3 protein expression in the gefitinib-resistant specimens.

Chest imaging was independently reviewed and scored by a thoracic radiologist, and all cases had undergone lung tissue biopsy. We identified five male combat veterans with DPO, median age 49 years [range: 32–64].
