Introduction Laryngeal neurofibromas are extremely rare, accounting for only 0.03 to 0.1% of benign tumors of the larynx. Objectives To report the first case of massive neck plexiform neurofibroma with intralaryngeal (supraglottic) extension in a 5-year-old boy with neurofibromatosis type 1 and to describe its treatment. Resumed Report This massive plexiform neurofibroma was surgically removed,...

Three patients, each with a solitary neurofibroma in the thigh, are described. The presenting complaint in each case was pain. A neurofibroma of a branch of the femoral nerve was found in two cases and an intraosseous neurofibroma of the femoral shaft was present in the third. An excellent recovery was observed in each of these three patients following surgical excision of the tumour. Attention...

RATIONALE Neurofibromatosis type I (NF-I) accounts for approximately 90% of neurofibromatosis. NF-I is an autosomal dominant genetic disease which results from the gene mutation of NF-I situated in chromosome 17q11.2. PATIENT CONCERNS A 32-year-old lady presented with a giant wing like structure on her back which started growing from her childhood. DIAGNOSIS A diagnosis of NF-I was confirme...

Neurofibromas are benign peripheral nerve tumors driven by NF1 loss in Schwann cells (SCs). Macrophages are abundant in neurofibromas, and macrophage targeted interventions may have therapeutic potential in these tumors. We generated gene expression data from fluorescence-activated cell sorted (FACS) SCs and macrophages from wild-type and mutant nerve and neurofibroma to identify candidate path...

Background Neurofibroma consists of abundant extracellular matrix and many types of cells, including Schwann cells (SCs), mast cells (MCs), fibroblasts and endothelial cells. As SCs have been found to be the cell of origin for neurofibroma, how MCs may migrate into the tumor has not been fully clarified. Given that chemokine receptor CCR3 is found predominantly expressed by differentiated MCs, ...

Neurofibroma is a benign neural tumor. Plexiform type of this tumor is rarely seen in oral cavity in solitary form. In this article, we present an 18-year-old male case with an isolated plexiform neurofibroma localized at buccal region without any other manifestation or family history of neurofibromatosis type 1.

Neurofibroma is a rare tumor of the oral cavity. It is generally associated with a generalized syndrome of neurofibromatosis but a few cases of the solitary intraoral lesions have also been reported. A one such rare case of neurofibroma of the lip is being presented with a note on the importance of early diagnosis and adequate treatment of this lesion.

A solitary neurofibroma arising in the retroperitoneal space without any other stagma of von Recklinghausen's disease is reported. Confusion with another nerve sheath tumor, a schwannoma is a diagnostic pitfall. Histochemical and immunohistochemical stainings of the tumor are useful for the diagnosis of solitary neurofibroma.

In humans, neurofibroma and schwannoma are distinct entities within the group of benign peripheral nerve sheath tumors. In the veterinary literature, these tumors are often classified together simply as benign peripheral nerve sheath tumors, and diagnostic criteria for their subclassification are not well established. We describe peripheral nerve sheath tumors with microscopic, immunohistologic...

Cutaneous neurofibromas are benign dermal tumors composed of spindle cells in a myxoid stroma containing numerous blood vessels. Here we describe 6 cases of solitary cutaneous neurofibroma showing unusually higher density of blood vessels in the stroma when compared to that of classical neurofibromas. We propose this lesion to be a new histopathological variant of neurofibroma and name it angio...
