Understanding Optic Gliomas
Optic gliomas are tumors that develop on the optic nerve and are commonly found in 15-20 percent of individuals with NF1 (neurofibromatosis type 1). These tumors typically grow slowly and can cause various symptoms. One common clinical manifestation is exophthalmos, an abnormal protrusion of the eyeball. Other symptoms may include decreased vision and precocious puberty, which typically occurs after the age of six. It is worth noting that most children receive a diagnosis of optic glioma around the age of three.
Cutaneous Neurofibromas
Neurofibromatosis often presents with the development of neurofibromas, which are tumors found in various parts of the body. These tumors can vary in shape and size. Cutaneous neurofibromas are specifically located on the skin and are characterized by their dome-shaped appearance, soft texture, and color, which can range from skin-colored to hyperpigmented. On the other hand, subcutaneous neurofibromas are found beneath the skin and are typically firmer and nodular in nature.
In most cases, these tumors become noticeable during puberty and can continue to grow in both size and number throughout adulthood. Additionally, it has been observed that pregnancy can also contribute to an acceleration in the growth of these tumors.
