Key learning points

What is already known about this subject

Silica is known to be immunogenic and is associated with autoimmune diseases.

There is a known association between ANCA-associated vasculitis and silica exposure, although the exact mechanism of injury is not known.

There are only a few case reports describing the association of silica exposure and IgA nephropathy.

What this study adds

This is the first documented case report, to our knowledge, of co-existing ANCA-associated vasculitis and IgA nephropathy linked to hilar lymphadenopathy due to silica exposure.

This case highlights the relevance of occupation exposures in renal disease, and the immune-stimulatory effect of silica.
