Clinical, pathologic, and genetic features of massive soft tissue neurofibromas in a Sicilian patient

2008

Abstract CONTEXT: Lipase maturation factor 1 (LMF1) gene is a novel candidate gene in severe hypertriglyceridemia. Lmf1 is involved in the maturation of lipoprotein lipase (LPL) and hepatic lipase in endoplasmic reticulum. To date only one patient with severe hypertriglyceridemia and related disorders was found to be homozygous for a nonsense mutation in LMF1 gene (Y439X). OBJECTIVE: The objective of the study was to investigate LMF1 gene in hypertriglyceridemic patients in whom mutations in LPL, APOC2, and APOA5 genes had been excluded. RESULTS: The resequencing of LMF1 gene led to the discovery of a novel homozygous nonsense mutation in one patient with severe hypertriglyceridemia and rec…

Neurofibromatosis of the nipple-areolar area : nine case reports

2010

Introduction: Neurofibromatosis type 1 is an autosomal dominant disorder that occurs across all ethnic groups and affects approximately one in 4000 individuals. One of the most noticeable characteristics of the disease is the development of neurofibromas. Case presentation: A total of 258 patients (131 women, 127 men) with neurofibromatosis type 1 were evaluated between 1994 and 2004 in our hospital's dermatology department. Nine patients (3.45%, 95% confidence limits 1.22 to 5.68) had neurofibromas of the breast. One of these nine patients presented with an extensive congenital plexiform neurofibroma in the outer quadrants of her right breast, extending to the nipple-areolar complex. Meanw…

Gingival neurofibroma in a neurofibromatosis type 1 patient: Case report

2007

Neurofibroma is a benign peripheral nerve sheath tumour. It is one of the most frequent tumours of neural origin and its presence is one of the clinical criteria for the diagnosis of type 1 neurofibromatosis (NF-I). Neurofibromatosis type 1 is an autosomal dominantly inherited disease due to an alteration in the long arm of chromosome 17. About 50% of NF-I patients have no family history of the disease. NF-I patients have skin lesions (café au lait spots and neurofibromas) as well as bone malformations and central nervous system tumours. Diagnosis is based on a series of clinical criteria. Gingival neurofibroma in NF-I is uncommon. Treatment of neurofibromas is surgical resection. The aim o…
