A resected case of schwannomatosis involving an extremely rare phrenic neurogenic plexiform schwannoma

This is the authors' abstract. We don't add key points for this paper.

In the thoracic cavity, neurogenic tumors are most commonly found in the posterior mediastinum, and most are solitary. Schwannoma is the most common neurogenic tumor and has multiple variants. The plexiform type is the rarest variant, with high potential for recurrence, unlike other variants. Plexiform schwannomas rarely occur in deep soft tissues or internal organs.1 We report a case of resection of schwannomatosis including plexiform schwannoma of phrenic nerve development; to our knowledge, no similar case has been reported thus far.
