متن کاملPrimary malignant peripheral nerve sheath tumor with eosinophilic cytoplasmic globules arising from the greater omentum in a dog.
A 10-year-old Golden Retriever dog had a solitary tumor mass arising from the greater omentum. Histologically, the tumor showed varying cellularity and patterns of cellular arrangement. In dense cellular areas, spindle-shaped cells were arranged in interlacing bundles. The sparse cellular area was characterized by loosely arranged fusiform cells. The neoplastic cells frequently contained PAS-po...
متن کاملMalignant Peripheral Nerve Sheath Tumor Arising from Neurofibromatosis
Neurofibromatosis type 1 (NF 1) is an inherited autosomal dominant disorder with an estimated incidence of 1 in 2,500 to 3,000 live births [1]. Neurofibromas are benign peripheral nerve sheath tumors developed from the proliferation of fibroblasts and Schwann cells. Wallac [2] categorized neurofibromas into four types: cutaneous neurofibromas of the epidermis or dermis, subcutaneous neurofibrom...
متن کاملMalignant peripheral nerve sheath tumor of the breast: case report
BACKGROUND Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma of ectomesenchymal origin. It is the malignant counterpart of benign soft tissue tumors like neurofibromas and schwannomas and may often follow them. Common sites include deeper soft tissues, usually in the proximity of a nerve trunk. Breast is an extremely rare location of this lesion and presentation as a breast ...
