Malignant Peripheral Nerve Sheath Tumour (Malignant Schwannoma) in the Diaphragm of a Goat

SummaryThis report describes a malignant schwannoma in the diaphragm of a 2-year-old goat. The immunohistochemical and histological features indicated a diagnosis of malignant schwannoma rather than neurofibrosarcoma. The diaphragm represents an unusual location for neoplasia in both domestic animals and human beings. A possible anatomical origin from the phrenic nerve is discussed.
