The American Journal of Dermatopathology, 1994
We report the clinical, histopathologic, and immunohistopathologic features of two cases of plexiform schwannoma. This rare benign tumor is worthy of recognition because it can be misdiagnosed as plexiform neurofibroma. Differentiation from plexiform neurofibroma is important because the latter is pathognomonic of von Recklinghausen disease and carries

Plexiform Fibrohistiocytic Tumor
Dermatology, 1991Two groups of cells, one rounded or oval and the other spindle-shaped, were found in a case of plexiform fibrohistiocytic tumor. Immunohistochemistry was strongly positive for alpha smooth muscle actin in most cells of both types but stronger in the spindle-shaped cells, suggesting a myofibroblastic origin.

Plexiform neurofibromas are among the most common and debilitating complications of neurofibromatosis type 1 (NF1). They account for substantial morbidity, including disfigurement, functional impairment, and may even be life threatening. Plexiform neurofibromas are also subject to transformation into malignant peripheral nerve sheath tumor (MPNST), a ...

AbstractFacial plexiform neurofibroma is a relatively rare manifestation of Von Recklinghausen's neurofibromatosis. Two patients with extensive facial tumor involvement are presented, each having undergone wide local resection after multiple previous local excisions had failed to control the tumor and its locally deforming and destructive effects.

We report a rare case of ossifying plexiform tumor in a 64‐year‐old female. The patient had a 2‐year history of gradual hardening of the right thumb pad and pain that radiated up the forearm. Physical examination showed a tender, mobile 2‐cm subcutaneous nodule distending the tip of the right thumb.

Plexiform (multinodular) schwannoma
The American Journal of Surgical Pathology, 1983We describe a rare variant of schwannoma characterized by a interconnecting multinodular growth mimicking a plexiform neurofibroma. The schwannoma recurred twice. The second recurrence was not excised and has not increased in size for 1 1/2 years. The patient is alive and well, 3 years and 4 months after the first excision with no clinical evidence of ...
