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 ...
Café au lait spot characteristic of NF1 Diagnostic criteria of neurofibromatosis type I, requiring at least 2 of the mentioned items. [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 (NF2 or NF II) is caused by mutations of the "Merlin" gene, [2] which seems to influence the form and movement of cells. The principal treatments consist of neurosurgical removal of the tumors and surgical treatment of the eye lesions. Historically the underlying disorder has not had any therapy due to the cell ...
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]
A lipoma is a benign tumor made of fat tissue. [1] They are generally soft to the touch, movable, and painless. [1] They usually occur just under the skin, but occasionally may be deeper. [1] Most are less than 5 cm (2.0 in) in size. [2] Common locations include upper back, shoulders, and abdomen. [4]
Schwannomatosis. Schwannomatosis is an extremely rare genetic disorder closely related to the more-common disorder neurofibromatosis (NF). Originally described in Japanese patients, [1] it consists of multiple cutaneous schwannomas, central nervous system tumors, and other neurological complications, excluding hallmark signs of NF.
Stephanie Williams, 40, developed a slight cough and thought it was allergies or undiagnosed COVID. Williams, who never smoked, asked her doctor for an X-ray — which is when a mass in her lung ...
