Neurofibromas, much like lipomas, are a common type of harmless nerve tumor that creates soft lumps on or beneath the skin. These growths can develop in any major or minor nerve throughout the body and may originate from various nerve bundles, known as plexiform neurofibromas. Typically, individuals diagnosed with neurofibromas experience mild or no symptoms. However, if the tumor puts pressure on or grows within the nerves, pain or numbness in the affected area may occur.
For a solitary neurofibroma that does not cause any symptoms or is smaller than an inch in diameter, it is often recommended to simply observe the tumor. Treatment for neurofibromas usually involves a combination of monitoring and surgical removal. The specific type of surgery performed depends on the tumor’s location, size, and whether it is intertwined with multiple nerves. The primary objective of the surgical procedure is to successfully eliminate the tumor while avoiding any damage to the nerves.
Resembling a cyst in appearance, a lipoma is a slow-growing mass composed of fat cells that typically resides in the subcutaneous layer of the skin, nestled between the skin and the underlying muscle layer. Although most lipomas are small, measuring less than 2 inches in diameter, they have the potential to increase in size. They possess a soft or doughy texture and can easily move when slight pressure is applied. Lipomas tend to develop in individuals during middle age, commonly appearing in the neck, shoulders, back, abdomen, and thighs.
Typically, lipomas do not cause tenderness, but they may induce pain if they enlarge and exert pressure on nearby nerves or contain a multitude of blood vessels. The exact cause of lipomas remains partially elusive, but it is believed that genetic factors contribute to their formation. To diagnose a lipoma, a physical examination, biopsy, and X-ray may be conducted.
Dermatofibromas, those tiny benign skin growths, have the ability to sprout up anywhere on the body. However, they tend to favor the lower legs, upper arms, and upper back. These peculiar nodules are more commonly found in adults rather than children and can display a range of colors including pink, red, grey, or brown. Interestingly, their hues may even shift over time. When touched, they feel solid and can be likened to a stone hiding beneath the skin. If you dare to pinch them from the sides, you may notice a slight indentation on the top.
While dermatofibromas can occasionally cause tenderness and itching, they are typically painless and rarely exceed a half-inch in diameter. Usually, only one nodule will make an appearance, but on occasion, multiple nodules may arise simultaneously.
