Intra parotid plexiform neurofibroma of the facial nerve is anextremely rare benign tumor, difficult to diagnose and manage, often considered pathognomonic neurofibromatosis type 1 (NF1 or von Recklinghausen's disease). Its diagnosis essentially pathological treatment primarily surgical avoid any degeneration. We report a case centered on region in 1-year-old child.

Neurofibromas of the penis, although very rare, are often associated with neurofibromatosis type 1. Primary solitary neurofibromas of the penis are extremely rare. We describe a 37-year-old man with a solitary neurofibroma in the dorsum of the penis. The patient reported difficulty with sexual intercourse owing to a penile mass and erectile dysfunction. After surgical excision of the neurofibro...

Neurofibromas are benign tumours arising from neurons andperineural cells. Although they are common inneurofibromatosis, occasionally solitary neurofibromas may occur. A rare case of solitary neurofibroma presenting as a giant gluteal mass in a male patient without a personal or family history of neurofibromatosis is presented. Pre-operative imaging gave useful information about the extent of t...

OBJECTIVE To describe the clinical findings in a patient who developed a neurofibroma, meningioma, and choroidal melanoma. METHODS Clinical and histopathological findings of the case are reviewed and presented. RESULTS The patient had a right superolateral periorbital neurofibroma, a right sphenoid wing meningioma, and a left choroidal juxtapapillary malignant melanoma. All 3 tumors are der...

We present an extremely unusual case of an extratemporal facial nerve malignant peripheral nerve sheath tumor (MPNST) arising from preexistent intratemporal neurofibroma, illustrating a difficulty in discriminating between perineural spread of the MPNST and the preexistent intratemporal neurofibroma on preoperative radiographic images. The most interesting point was that preoperative CT scan an...

Neurofibromas of the urinary bladder are an exceedingly rare entity and are considered mostly in conjunction with the disease of neurofibromatosis type 1. The fortuitous discovery of vesical plexiform neurofibromas without other stigmata of the disease is presented in a 57-year-old male patient. The course of his condition, modalities of investigation and a non-precedent treatment plan are demo...

BACKGROUND: Plexiform neurofibromas (PNF) are benign tumors of the peripheral nerve which mostly develop in patients with neurofibromatosis type 1 (NF1). Surgical interventions are usually not applied to children with small tumors. These are rather restricted to debulking of larger tumors in adults that cause clinical complications or aesthetic disfigurement. In most cases, a total resection of...

Introduction: Diagnosis of neurofibroma usually is based on the specific morphology and arrangement of mesenchymal cells in routine Hematoxylin and Eosin (H&E) sections, and detection of mast cells supports the diagnosis. Sometimes definite diagnosis from other mesenchymal lesions may be difficult. The aim of the present study was to compare S100 expression and mast cells count (as Gold Standar...
