3) While patients with segmental NF may exhibit some of these same findings, the distribution of neurofibromas
is often limited to one dermatome.
Medallion-like dermal dendrocyte hamartoma: a case misdiagnosed as neurofibroma
Solitary Plexiform Neurofibroma
of the Gingiva: Unique Presentation in the Oral Cavity.
In our case, involvement of sacroiliac joint was secondary to juxtaarticular plexiform neurofibroma
with massive invasion of the right sacroiliac joint.
Bajo anestesia general se realizo la diseccion hasta la aponeurosis cervical profunda con diseccion del paquete vasculonervioso cervical (arteria carotida, vena yugular interna y nervio neumogastrico), logrando la reseccion del neurofibroma
, tumor solido de consistencia dura, forma ovalada y sin abundante vascularizacion (figura 3).
Abstract: Peripheral nerve sheath tumors are a heterogeneous group of neoplasms that comprise neurofibromas
, schwannomas, neurilemmomas, and perineuromas.
Lesions like bronchogenic cyst and neurofibroma
were suspected by CT imaging, but surgical excision proved to be both diagnostic and therapeutic.
lacks capsule, rich in mucopolysaccharide ground substance and has fewer axons.
An incision biopsy from the posterior mandibular lesion which microscopically revealed interlacing bundles of spindle shaped cells with wavy nuclei, delicate collagen fibres, plump fibroblasts, and a strong positive reaction with S-100 (detection system, HRP polymer) confirmed the diagnosis of simple neurofibroma
(Figures 2(a) and 2(b)).
18-FDG-PET-CT scan helps in differentiating MPNST from benign neurofibroma
in NF-1 patients and detecting malignant transformation of benign plexiform neurofibromas
The schwanoma and neurofibroma
differ histologically and histogenetically; the schwannoma is derived from the Schwann cells and the neurofibroma
from the fibroblasts of the perineurium.
can be differentiated from Bednar tumour by more extensive storiform growth and strong positivity for CD34 in latter.
