| The most frequent forms are bladder papilloma and bladder carcinoma. Rarer forms are fibroma, myoma and neurofibroma. |
|
| When multiple neurofibroma are present, neurofibromatosis should be considered. |
|
| Cellular neurofibroma with atypia is an unusual variant. |
|
| Additionally, it has also been reported that it can overlie some benign and malignant lesions, including some nevi, melanoma and neurofibroma. |
|
| Differential diagnosis should include neurofibroma, ganglion cysts, malignant tumors, lipomas, and xanthomas. |
|
| The differential diagnosis of a dermatofibroma includes neurilemmoma, neurofibroma, piloleiomyoma, cyst, hypertrophic scar, and tophus. |
|
| The treatment of choice for a laryngeal neurofibroma is complete surgical resection with preservation of laryngopharyngeal function. |
|
| A key event in the initiation of neurofibroma development is biallelic inactivation of the NF1 gene. |
|
| In this case, firm fibrotic lesions to consider include myofibroma, irritation fibroma, neurofibroma, angiofibroma, myofibromatosis, and fibrotic pyogenic granuloma. |
|
| Histopathologic examination identified the mass as a neurofibroma. |
|
| Solitary neurofibroma of the maxillarysinus and pterygopalatine fossa. |
|
| Neurofibroma is a benign tumour which originates in the sheath cells of the nerve fibres. Neurofibromas are classified into so-called solitary tumours, with clear edges, and plexiform tumours, which spread randomly. |
