| Abstract |
|
Perineuriomas(tumors of perineurial cells) are relatively rare, benign peripheral nerve sheath-originated neoplasms, presenting
extraneural or intraneural tumors. Extraneural perineuriomas seem to be more common than intraneural perineuriomas.
Extraneural perineuriomas are found mainly in skin and soft tissues. Soft tissue perineurioma is a kind of extraneural
perineuriomas, and it is the most common type of perineuriomas. Histopathologically, soft tissue perineurioma is characterized by
well-circumscription, fibromyxoid stroma, and bland spindle cells representing the fascicles or whirling growth pattern, which is
accentuated on the perivascular zones. Herein, we present one case of extraneural soft tissue perineurioma occurring on the
lower back region. |
