Koenen's tumor
Koenen's Tumor
Koenen's tumor (pronunciation: /koʊˈɛnənz ˈtuːmər/), also known as periungual fibroma, is a type of fibroma that typically develops around the nails. It is a common symptom of Tuberous Sclerosis Complex (TSC), a genetic disorder that causes non-cancerous (benign) tumors to grow in different parts of the body.
Etymology
The term "Koenen's tumor" is named after the Dutch dermatologist Jan Koenen, who first described this condition in the medical literature.
Description
Koenen's tumors are small, benign, fibrous growths that usually appear around or under the nails (periungual) of the fingers and toes. They are often skin-colored or slightly pink, and can vary in size. These tumors are typically painless, but can cause discomfort or interfere with normal nail growth.
