Intrapulmonary Ancient Schwannoma: a Rare Tumour.

Schwannomas are benign encapsulated neoplasms which arise from Schwann cells of the neural sheath. Ancient schwannoma is a rare variant of schwannoma which is often misdiagnosed as a malignant neoplasm owing to degenerative changes. They are known to show degenerative nuclear atypia, cystic degeneration, hyalinization, myxoid change and haemorrhage. We present a rare case of an intrapulmonary ancient schwannoma in a 34-year-old female patient.
