Fibrofolliculomas and trichodiscomas

Fibrofolliculomas and trichodiscomas usually appear as small, smooth, flat or circular raised bumps (papules), most commonly on the face, ears, neck, and upper body. They are thought to belong to the same spectrum of harmless (benign) skin tumors. Trichodiscomas are the same color as the surrounding skin, unlike fibrofolliculomas which are usually lighter than the surrounding skin. These two kinds of lesions may look like pimples, but they do not go away with time and will not be able to be ‘popped’ like a whitehead pimple. Both of these skin lesions occur as solitary and multiple papules (bumps).

How do fibrofolliculomas and trichodermas form?

They arise from or around hair follicles and their cause is largely unknown, though it may be linked to genetics.

What are fibrofolliculomas and trichodiscomas a symptom of?

Both of these kinds of lesions are characteristically seen in a condition known as Birt-Hogg-Dubé (BHD) syndrome. BHD is a rare, genetically transmitted condition that can cause, in addition to these kinds of benign tumors, susceptibility to cancers such as renal cell carcinoma and other conditions such kidney (renal) and lung (pulmonary) cysts. The symptoms that manifest in each family are unique and can be any combination of these symptoms. If you are diagnosed with fibrofolliculomas or trichodiscomas, it is imperative to be evaluated by a genetics specialist and if diagnosed with BHD, to be screened for internal organ cancers, such as renal cell carcinoma. There may be cases of fibrofolliculomas and trichodiscomas that are not related to any other underlying genetic conditions.

Who is most likely to develop fibrofolliculomas and trichodiscomas?

People over the age of 40 with BHD are most likely to develop these skin lesions on the face and upper body. They also often occur in children and young adults and affect both females and males.
