Lhermitte-Duclos Disease Associated with Cowden's Disease Lhermitte-Duclos Disease Associated with Cowden's Disease Case Report—— Hiroshi YUASA, Takashi MOTOKISHITA, Sumitaka TOKITO, Masayoshi TOKUNAGA*, and Masamichi GOTO** Departments of Neurosurgery and *Pathology, Kagoshima City Hospital, Kagoshima; **2nd Department of Pathology , Kagoshima University School of Medicine, Kagoshima Abstract A 49-year-old Japanese male with Lhermitte-Duclos disease subsequently developed a very rare associa tion with Cowden's disease. Partial tumor removal established the diagnosis of Lhermitte-Duclos dis ease. Follow-up examinations discovered the presence of Cowden's disease. Long-term follow-up of patients with Lhermitte-Duclos disease is essential to identify signs of Cowden's disease, which carries the risk of developing malignancy.

Abstract: Patients diagnosed with neurofibromatosis type 2 (NF2) are extremely likely to develop meningiomas, in addition to vestibular schwannomas. Meningiomas are a common primary brain tumor; many NF2 patients suffer from multiple meningiomas. In NF2, patients have mutations in the NF2 gene, specifically with loss of function in a tumor-suppressor protein that has a number of synonymous names, including: Merlin, Neurofibromin 2, and schwannomin. Merlin is a 70 kDa protein that has 10 different isoforms. The Hippo Tumor Suppressor pathway is regulated upstream by Merlin. This pathway is critical in regulating cell proliferation and apoptosis, characteristics that are important for tumor progression.

  • Information About Mosaic Neurofibromatosis Type 2 (NF2)
    Information about mosaic Neurofibromatosis type 2 (NF2) NF2 occurs because of a mutation (change) in the NF2 gene. When this change is present at the time of conception the changed gene will be present in all the cells of the baby. When this mutation occurs later in the development of the forming embryo, the baby will go on to have a mix of cells: some with the “normal” genetic information and some with the changed information. This mix of cells is called mosaicism. Approximately half the people who have a diagnosis of NF2 have inherited the misprinted NF2 gene change from their mother or father who will also have NF2. They will have that misprinted gene in all the cells of their body. When they have their children, there will be a 1 in 2 chance of passing on NF2 to each child they have. However about half of people with NF2 are the first person in the family to be affected. They have no family history and have not inherited the condition from a parent. When doctors studied this group of patients more closely they noticed certain characteristics. Significantly they observed that fewer children had inherited NF2 than expected some people in this group had relatively mild NF2 NF2 tumours in some patients tended to grow on one side of their body rather than both sides that when a blood sample was tested to identify the NF2 gene, the gene change could not be found in 30-40% of people This lead researchers to conclude that this group of people were most likely to be mosaic for NF2 i.e.

A 38-year-old woman presented with paraparesis. Magnetic resonance imaging revealed an intramedullary lesion within the lower thoracic spinal cord and conus medullaris, which was removed surgically. Pathological investigation showed anaplastic astrocytoma. This case confirms that the diagnosis criteria set by the National Institute of Health Consensus Development Conference can be useful to differentiate ependymoma from astrocytoma when making a preoperative diagnosis of intramedullary spinal cord tumor in patients of NF-1.

  • Neurofibromatosis Type 1 (Nf1) a Guide for Adults and Families
    1 NEUROFIBROMATOSIS TYPE 1 (NF1) A GUIDE FOR ADULTS AND FAMILIES Introduction Neurofibromatosis (NF) is a collective name for a group of genetic conditions that affect the nervous system. NF causes benign (non cancerous) lumps to grow on nerves. These lumps can grow on nerve endings in the skin where they can be seen clearly; the lumps can also grow on deeper nerves within the body. Neurofibromatosis occurs all over the world in all races. It affects men and women equally. There are two main types of Neurofibromatosis: Neurofibromatosis type 1 (NF1) and Neurofibromatosis type 2 (NF2). They are two completely different and separate conditions. People who have NF will have one type or the other. NF1 cannot change into NF2. THIS INFORMATION IS ABOUT NF1 ONLY NEUROFIBROMATOSIS TYPE 1 (NF1) is a common genetic condition. A genetic condition is one that can be passed on in families. Approximately 1 in every 2,500/3000 people is born with NF1. In the UK, every day a child is born with NF1. There are about 25000 people in the UK with a diagnosis of NF1. NF1 varies widely in how it affects people. Many people with NF1 will be affected very mildly and may have nothing more than skin changes. A minority of people (about a third) who have NF1 will have health problems linked to the diagnosis at some time in their life. Some of these problems will be mild and easily treated, others will be more severe. 2 At present, doctors cannot predict who is going to develop health problems linked to having a diagnosis of NF1.

  • Current Understanding of Neurofibromatosis Type 1, 2, And
    International Journal of Molecular Sciences Review Current Understanding of Neurofibromatosis Type 1, 2, and Schwannomatosis Ryota Tamura Department of Neurosurgery, Kawasaki Municipal Hospital, Shinkawadori, Kanagawa, Kawasaki-ku 210-0013, Japan; [email protected] Abstract: Neurofibromatosis (NF) is a neurocutaneous syndrome characterized by the development of tumors of the central or peripheral nervous system including the brain, spinal cord, organs, skin, and bones. There are three types of NF: NF1 accounting for 96% of all cases, NF2 in 3%, and schwannomatosis (SWN) in <1%. The NF1 gene is located on chromosome 17q11.2, which encodes for a tumor suppressor protein, neurofibromin, that functions as a negative regulator of Ras/MAPK and PI3K/mTOR signaling pathways. The NF2 gene is identified on chromosome 22q12, which encodes for merlin, a tumor suppressor protein related to ezrin-radixin-moesin that modulates the activity of PI3K/AKT, Raf/MEK/ERK, and mTOR signaling pathways. In contrast, molecular insights on the different forms of SWN remain unclear. Inactivating mutations in the tumor suppressor genes SMARCB1 and LZTR1 are considered responsible for a majority of cases. Recently, treatment strategies to target specific genetic or molecular events involved in their tumorigenesis are developed. This study discusses molecular pathways and related targeted therapies for NF1, NF2, and SWN and reviews recent clinical trials which involve NF patients.

  • The Pathogenesis of Neurofibromatosis 1 and Neurofibromatosis 2
    Chapter_3_p23-42 10/11/04 5:55 PM Page 23 3 The Pathogenesis of Neurofibromatosis 1 and Neurofibromatosis 2 The neurofibromatoses are genetic disorders. NF1 and NF2 are each caused by a mutation in a known specific gene. The quest to understand how these disorders originate and progress (their pathogenesis) received a significant boost when researchers identified the causative genes. The leading theories about the pathogenesis of NF1 and NF2 are discussed in this chapter. Because the search for the biological cause of schwanno- matosis was still underway when this book went to press, less is known about its pathogenesis (see Chapter 12). N A Search for Answers In 1990, two groups of scientists working separately located the NF1 gene on chromosome 17 and characterized its protein product, neurofi- bromin.1–3 In 1993, another two teams working separately identified the NF2 gene on chromosome 22; one named its protein “merlin”4 and the other “schwannomin.”5 Once the genes were identified, work could begin on better understanding how mutations lead to tumor formation and other manifestations. The search for answers, however, has been daunting. There is proba- bly no single answer to the question, What causes NF1 and NF2? Just as 23 Chapter_3_p23-42 10/11/04 5:55 PM Page 24 24 Neurofibromatosis these disorders cause various types of manifestations, so too there appear to be multiple molecular mechanisms at work. When trying to understand the pathogenesis of a disorder, scientists may combine two techniques that approach the question from different directions. The traditional phenotypical approaches analyze the physical manifestations of the disorders, such as what cells are involved and how they function, and then work backward to determine what gene might cause these abnormalities.
