Is Dermatofibrosarcoma Protuberans (DFSP) contagious?

Dermatofibrosarcoma protuberans (DFSP) is not contagious and cannot be spread to others through touch, physical contact, or proximity. It is a rare, slow-growing type of soft tissue sarcoma that arises from genetic mutations within the skin cells, meaning there is zero risk of transmission to family members, caregivers, or the general public.

What is the cause of Dermatofibrosarcoma protuberans (DFSP)?

Dermatofibrosarcoma protuberans (DFSP) is caused by a specific genetic translocation, most commonly involving the fusion of the COL1A1 and PDGFB genes on chromosomes 17 and 22. This genetic error leads to the overproduction of a growth factor that causes cells to multiply uncontrollably. Because Dermatofibrosarcoma protuberans (DFSP) is a result of these internal molecular changes, it is considered a sporadic condition rather than an infectious disease.

Why is there confusion regarding contagion?

Because Dermatofibrosarcoma protuberans (DFSP) presents as a visible lump or lesion on the skin, it is sometimes mistakenly perceived as an infectious rash or wart. It is important to clarify that Dermatofibrosarcoma protuberans (DFSP) does not involve viruses, bacteria, or fungi. Common misconceptions often stem from the visual appearance of the skin, leading to unnecessary social stigma. Living with, hugging, or sharing personal items with someone who has Dermatofibrosarcoma protuberans (DFSP) poses absolutely no health risk to others.

Are there environmental triggers for DFSP?

Unlike some skin cancers, Dermatofibrosarcoma protuberans (DFSP) is not caused by UV radiation or sun exposure. While the exact reason these genetic mutations occur is not fully understood, research indicates several key characteristics:

• The condition typically appears in adults between the ages of 20 and 50.


• It is extremely rare, with an estimated annual incidence of 0.8 to 4.5 cases per million people.


• Previous trauma to the skin, such as surgical scars or burns, has been reported in a small percentage of cases, though a direct causal link remains unproven.

Next steps

• Consult a dermatologist or an oncologist specializing in soft tissue sarcomas for an accurate diagnosis.


• Connect with the 172 members on DiseaseMaps.org who are living with Dermatofibrosarcoma protuberans (DFSP) to share experiences and reduce isolation.


• Educate friends and family members by sharing reliable information to dispel myths about the condition.
