A harmless soft fleshy skin growth.
Neurofibromas are pink or skin-coloured growths, ranging in size from a few millimetres to a few centimetres. The growth typically appears on the arms, legs, abdomen, chest or back, but can appear on any part of the body.
One of the most distinctive characteristics of a neurofibroma is that it is soft and mobile. Physically, a neurofibroma is soft enough that you can fold it inward like a button.
Easily confused with a skin tag, the lesion can be misdiagnosed. However, skin tags tend to be smaller and on a narrower stalk than neurofibromas, and they are most commonly found in the skin folds of people who are overweight.

Why does Neurofibroma matter?
Solitary neurofibromas are not a cause for concern.
The development of multiple neurofibromas, however, could indicate neurofibromatosis, a childhood genetic disorder.
Neurofibromatosis may present with subtle early symptoms, including:
- multiple neurofibromas
- Several cafe au lait patches (2-10 cm in diameter) typically present at birth
- freckles under the armpits.
To confirm a diagnosis of a solitary neurofibroma, the lesion will need to be excised and then examined pathologically. The pathology will reveal a benign tumour of the spindle cells.
Neurofibromas do not cause any harm, despite being classified as a tumour.
A suspected neurofibroma will usually be left alone unless it causes cosmetic concerns or catches on things like clothing.
