Basaloid Follicular Hamartoma Syndrome
- Basaloid follicular hamartoma syndrome can be hereditary or nonhereditary and is characterised by benign hair follicle tumours.
- Related skin condition: Basaloid follicular hamartoma.
Brooke-Spiegler Syndrome (BSS)
- BSS is an inherited syndrome characterised by multiple skin appendage tumours.
- Related skin conditions: Cylindroma, Trichoepithelioma and Spiradenomas.
- Cowden syndrome is a rare disorder characterised by multiple benign growths which develop on the skin and the lining of the mouth and nose (photos). The proteins involved in Cowden and BHD have overlapping signalling pathways.
- Related skin condition: Trichilemmoma
- Rombo syndrome is a rare disease characterised by a redness of the skin and the development of papules.
- Related skin condition: Telangiectasia
Familial multiple discoid fibromas (FMDF)
- FMDF is similar to BHD syndrome but only leads to skin lesions, with no kidney or lung symptoms. People considered to be affected by FMDF have not been found to have alterations in their Folliculin gene; however, FMDF may involve similar protein pathways to BHD.
- Read more about FMDF on the BHD Research Blog.
Tuberous Sclerosis Complex (TSC)
- TSC is a genetic disorder characterized by the growth of numerous benign tumours in many parts of the body including the skin. The proteins involved in TSC and BHD have overlapping signalling pathways.
- Related skin condition: Angiofibromas
