Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

What is a neurofibroma?

A neurofibroma is a non-cancerous (benign) tumor that develops from the cells and tissues that cover nerves.[1] Some people who develop neurofibromas have a genetic condition known as neurofibromatosis (NF). There are different types of NF, but type 1 is the most common.

What is neurofibromatosis type 1?

Neurofibromatosis type 1 (NF1) is an inherited condition characterized by changes in skin coloring (pigmentation) and the growth of tumors along nerves in the skin, brain, and other parts of the body. The signs and symptoms of this condition vary widely among affected people. Mutations in the NF1 gene cause neurofibromatosis type 1. This condition is considered to have an autosomal dominant pattern of inheritance.[2]

What is a dermal eccrine cylindroma?

Dermal eccrine cylindromas are non-cancerous (benign) sweat gland tumors.[3] They most commonly occur on the head and neck and rarely become cancerous (malignant). "Dermal" indicates that these tumors are found on the skin. An eccrine gland is a type of simple sweat gland that is found in almost all regions of the skin.[4]  Solitary cylindromas occur sporadically and typically are not inherited.[3] They usually begin to form during mid-adulthood as a slow-growing, rubbery nodule that causes no symptoms. The development of multiple cylindromas can be hereditary and is inherited in an autosomal dominant manner.[3]  Individuals with the inherited form begin to develop numerous, rounded nodules of various size shortly after puberty. The tumors grow very slowly and increase in number over time.
