Fibrous papule of the face, also known as facial angiofibroma, is a common benign skin growth that appears on the face, especially around the nose and cheeks. These papules are small, dome-shaped, flesh-colored or pinkish, and have a firm and smooth texture. They usually occur in adults and are more common in men than women.
The exact cause of fibrous papules is unknown, but they are thought to be associated with genetic factors, hormonal imbalances, and sun exposure. Although these papules are harmless and do not usually require treatment, some people may choose to have them removed for cosmetic reasons.
Types
There are several types of fibrous papule of the face that have been identified. These include:
- Classical fibrous papule: This is the most common type of fibrous papule and typically appears on the nose. It is a small, firm, dome-shaped bump that is usually flesh-colored.
- Angiofibroma: This type of fibrous papule appears as a small, red or pinkish bump and may have visible blood vessels on the surface. It is most commonly found on the nose and cheeks.
- Perifollicular fibroma: This type of fibrous papule appears as a small, flesh-colored bump and is typically located around hair follicles. It is most commonly found on the face and neck.
- Clear cell fibrous papule: This type of fibrous papule appears as a small, dome-shaped bump that is usually flesh-colored or slightly pinkish. It is characterized by the presence of clear cells within the growth.
- Fibroepithelial polyp: This type of fibrous papule appears as a small, flesh-colored or pinkish bump and is typically located in areas where there is friction or rubbing, such as the neck or underarms.
Causes
While the exact cause of FPF is unknown, there are several factors that may contribute to their development, and the top causes of FPF and provide detailed explanations for each one.
- Genetics: It is believed that FPF may have a genetic component, as they tend to run in families.
- Age: FPF are more commonly seen in middle-aged and elderly individuals.
- Hormones: Hormonal changes, such as those that occur during pregnancy, may contribute to the development of FPF.
- Sun exposure: Prolonged sun exposure can damage the skin and lead to the development of FPF.
- Trauma: Repeated trauma to the skin, such as from picking at acne, can lead to the formation of FPF.
- Rosacea: People with rosacea, a common skin condition that causes redness and inflammation, may be more prone to developing FPF.
- Acne: FPF may develop as a result of previous acne lesions.
- Tuberous sclerosis: This genetic disorder can lead to the formation of FPF.
- Birt-Hogg-Dubé syndrome: Another genetic disorder that can cause FPF.
- Cowden syndrome: This genetic disorder is associated with the development of multiple skin lesions, including FPF.
- Neurofibromatosis type 1: This genetic disorder can cause the development of multiple benign skin tumors, including FPF.
- Gardner syndrome: This rare genetic disorder can lead to the development of FPF.
- Proteus syndrome: Another rare genetic disorder that can cause FPF.
- HIV: People with HIV may be more prone to developing FPF.
- Chronic renal failure: FPF may occur more frequently in people with chronic renal failure.
- Hypothyroidism: This condition, in which the thyroid gland does not produce enough hormones, may be associated with the development of FPF.
- Medications: Certain medications, such as cyclosporine, may increase the risk of developing FPF.
- Diabetes: People with diabetes may be more prone to developing FPF.
- Immunodeficiency: Certain immunodeficiency disorders may be associated with the development of FPF.
- Radiation therapy: Radiation therapy, particularly to the face, may increase the risk of developing FPF.

While fibrous papules of the face are not typically harmful, it is important to have them evaluated by a dermatologist to confirm the diagnosis and rule out any other potentially serious conditions. Your dermatologist can also recommend appropriate treatment options based on the severity and location of the fibrous papules.
Diagnosis
However, there are some tests that may be used to confirm the diagnosis or rule out other conditions that may have similar symptoms. Here are diagnosis and tests that can be used for fibrous papules of the face:
- Physical Examination – A dermatologist can often diagnose a fibrous papule by simply examining the skin.
- Dermoscopy – This technique uses a specialized microscope to examine the skin in greater detail, allowing for a more accurate diagnosis.
- Biopsy – A small sample of tissue is taken from the papule and examined under a microscope to confirm the diagnosis.
- Shave Biopsy – A small blade is used to shave off the top layer of the papule for examination.
- Punch Biopsy – A small circular tool is used to remove a deeper sample of tissue for examination.
- Immunohistochemistry – A laboratory technique that uses antibodies to detect specific proteins in the tissue sample, which can help confirm the diagnosis.
- Polymerase Chain Reaction (PCR) – A laboratory technique that amplifies and detects DNA in the tissue sample, which can help identify any viral or bacterial infections.
- Culture – A laboratory test that attempts to grow any infectious organisms in the tissue sample.
- Skin Scraping – A small sample of skin is scraped off the papule and examined under a microscope for any signs of infection or inflammation.
- Blood Tests – These tests can help rule out any underlying medical conditions that may be causing the papule.
- Patch Testing – A technique that involves applying small patches of potential irritants to the skin to see if they cause a reaction.
- Allergy Testing – A series of tests that can identify any allergies that may be causing the papule.
- Skin Prick Test – A test that involves pricking the skin with a small amount of a potential allergen to see if it causes a reaction.
- Skin Biopsy with Elastic Stain – A laboratory technique that stains the tissue sample with elastic stains to examine the elastic fibers in the tissue, which can help confirm the diagnosis.
- Ultrasonography – A diagnostic imaging technique that uses high-frequency sound waves to create images of the tissue inside the body, which can help identify any abnormalities.
- Magnetic Resonance Imaging (MRI) – A diagnostic imaging technique that uses powerful magnets and radio waves to create images of the tissue inside the body, which can help identify any abnormalities.
- Computed Tomography (CT) Scan – A diagnostic imaging technique that uses X-rays and computer technology to create detailed images of the tissue inside the body, which can help identify any abnormalities.
- Endoscopy – A procedure that involves inserting a flexible tube with a camera into the body to examine the tissue inside, which can help identify any abnormalities.
- Digital Photography – A technique that involves taking high-resolution photographs of the papule to track any changes over time.
- Video Dermoscopy – A technique that uses a digital camera and a specialized microscope to examine the papule in greater detail and record any changes over time
Treatment
Here are treatments for fibrous papules of the face, ranging from over-the-counter remedies to professional medical procedures.
