Pertaining to location, the neoplasm predominantly demonstrates configurations such as intra-neural or extra-neural, confined to the soft tissue. Perineurioma was initially scripted by Lazarus and Trombetta in 1978 and is additionally nomenclated as localized hypertrophic neuropathy1. Extra-neural soft tissue perineurioma and mucosal (intestinal) perineurioma are frequent, in contrast to intra-neural perineurioma or localized hypertrophic neuropathy subtype12. Keywords: Soft tissue perineurioma; mucosal (intestinal) perineurioma
