Removal of plexiform neurofibromas is difficult because they can be large and cross tissue boundaries. However, besides pain, plexiform neurofibromas are sometimes removed due to the possibility of malignant transformation. The following examples show that plexiform neurofibromas can form anywhere and can make surgical resection difficult:
Neurofibromatosis (NF) refers to a group of three distinct genetic conditions in which tumors grow in the nervous system. [1] The tumors are non-cancerous (benign) and often involve the skin or surrounding bone. [1] Although symptoms are often mild, each condition presents differently. Neurofibromatosis type I (NF1) is typically characterized ...

[6]The following is a list of conditions and complications associated with NF-1, and, where available, age range of onset and progressive development, occurrence percentage of NF-1 population, method of earliest diagnosis, and treatments and related medical ...
Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition that may be inherited or may arise spontaneously, and causes benign tumors of the brain, spinal cord, and peripheral nerves. The types of tumors frequently associated with NF2 include vestibular ...
Smoking tobacco is so harmful to the body that it changes a person’s immune system, leaving them vulnerable to more disease and infection even years after they’ve quit, a new study found.
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. [1] All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved ...
Deaths. Not reported. Smoking-related interstitial fibrosis (SRIF) is an abnormality in the lungs characterized by excessive collagen deposition within the walls of the air sacs (interstitial fibrosis). This abnormality can be seen with a microscope and diagnosed by pathologists. It is caused by cigarette smoking. [1][2]
