Abstract
Nerve sheath myxoma(NSM) is a rare cutaneous neoplasm of uncertain histogenesis. NSM can be divided into two groups; NSM1 (a myxoid NSM) and NSM2 (a cellular neurothekeoma). NSMs are characterized histologically by well-defined, lobular or plexiform dermal proliferation of stellate, spindle-shaped cells embedded in abundant myxoid stroma. A variable amount of nerve fascicles are entrapped within and around the tumor. Two variants of NSM share the same features to a certain degree but differ in cellularity and mucin deposition. We report two cases of NSMs with different clinical and histopathologic features.
