Benign Cutaneous Peripheral Nerve Sheath Tumor with Hybrid Features: Report of Two Cases with Schwannoma/Perineurioma and Schwannoma/Neurofibroma Components
نویسندگان
چکیده
Hybrid benign peripheral nerve sheath tumors are rare tumors exhibiting areas of more than one neural neoplasm such as schwannoma/neurofibroma, neurofibroma/perineurioma, or schwannoma/perineurioma. These tumors usually arise in the skin of the extremities and trunk, and less commonly affect extracutaneous sites. Here we report two cases of these tumors exhibiting hybrid features of schwannoma/perineurioma and schwannoma/neurofibroma located in the scalp and the ankle, respectively.

24-year-old woman with an internal auditory canal mass. Hybrid peripheral nerve sheath tumor with schwannoma/perineurioma components.
Benign peripheral nerve sheath tumors are divided into schwannomas, neurofibromas and perineuriomas. In recent years, tumors with hybrid features, composed of multiple, discrete areas of different histological types, were described. These tumors may represent a diagnostic challenge. A 24-year-old woman with multiple sclerosis was found to have a 1.3 cm TV × 0.7 cm AP T2 intermediate lesion with...
متن کاملSchwannoma of Gingiva: a rare case report
Schwannoma is a rare benign neural neoplasm derived from Schwann cells of the peripheral nerve sheath. Schwannoma accounts for 25% to 48% of all neoplasm cases in the head and neck region. Oral Schwannoma is an uncommon soft tissue tumor comprising of 1% of all Schwannomas. Tongue is the most common location for oral schwannoma. Occurrence of gingival schwannoma is very rare and less than 10 ca...
متن کاملA Soft Tissue Perineurioma and a Hybrid Tumor of Perineurioma and Schwannoma
Perineuriomas are composed of differentiated perineurial cells. Perineuriomas have been recently recognized by the immunoreactivity for epithelial membrane antigen (EMA). Microscopically, perineuriomas show proliferation of spindle cells with wavy nuclei and delicate elongated bipolar cytoplasmic processes. The tumor cells are usually negative for the S-100 protein. Ultrastructurally, perineuri...

Very recently, Requena et al. have demonstrated the detailed clinicopathological features of 9 cases of a benign cutaneous plexiform nerve sheath tumor with hybrid characteristics of perineurioma and cellular neurothekeoma, given the name as a benign cutaneous plexiform hybrid tumor of perineurioma and cellular neurothekeoma, all of which were peculiarly located on the lips. Herein we described...
متن کاملNeurofibroma, schwannoma or a hybrid tumor of the peripheral nerve sheath?
Classically, the different subtypes of the peripheral nerve sheets tumors display typical morphological features which differentiate them from the other nervous tumors. Either schwannoma or neurofibroma have characteristic histological and immunohistochemical features. We present a case of peripheral nerve sheets hybrid tumor which have had histological and immunohistochemical features of neuro...
