Birt–Hogg–Dubé syndrome, also Hornstein-Birt-Hogg-Dubé syndrome,[1] is constellation of findings due to a FLCN (folliculin) gene mutation.[2] It is abbreviated BHD syndrome.
Features
BHD syndrome is characterized by:[3][4]
- Skin lesions of face, neck and anterior trunk (~80% of individuals with syndrome):
- Fibrofolliculoma.
- Trichodiscoma.
- Acrochordon.
- Renal tumours (~25-35% of individuals):
- Variable penetrance (autosomal dominant).
- Lung cysts - inferior to carina (~80% of individuals with syndrome).
- Multiple basal lung cysts - may be significant.[6]
- Spontaneous pneumothorax (~25% of individuals with syndrome).[4]
Note:
- May be seen with a mix of oncocytic renal tumours - known as renal oncocytosis.
