Intramedullary melanotic schwannoma
We present a case of an intramedullary melanotic schwannoma (IMS) of the thoracic spinal cord. To our knowledge, this is the seventh reported case of an IMS of the central nervous system. Schwannomas are benign nerve sheath tumors of neural crest origin composed entirely of well differentiated Schwann cells that typically occur in peripheral nerves. Both the intramedullary location and the mela...
متن کاملMelanotic spinothoracic schwannoma.
A dumb-bell mediastinal melanotic schwannoma is described, and the rarity of this type of tumour emphasised. The tumour was resected by simultaneous laminectomy and posterior thoracotomy. The patient is well four years after operation. The pathology of the tumour is described and the origin of melanotic cells is discussed.
متن کاملMalignant melanotic schwannoma of the bronchus.
A case of malignant melanotic schwannoma arising in the right upper lobe bronchus of a 27 year old man is presented. Tumours of this type most commonly occur in spinal nerve roots and are generally considered to be benign. The behaviour of those originating elsewhere is less predictable. As far as we are aware this is the first reported case affecting the respiratory tract.
متن کاملPrimary Melanotic Schwannoma with Typical Histology.
We present a case of a 17-year male with a soft tissue density spreading from the neural foramina (T3) of the spinal cord and involving the right upper thoracic cavity. We managed the patient through surgical intervention and resected the complete tumor. Gross definition and microscopic findings of the resected tissue revealed the definitive diagnosis of melanotic schwannoma. The histological c...
متن کاملPsammomatous Melanotic Schwannoma: A Challenging Histological Diagnosis
Psammomatous melanotic schwannoma (PMS) is a rare pigmented tumor that can be part of the Carney complex. Here, we describe the case of a 35-year-old female patient presenting an isolated subcutaneous PMS. Histopathological analysis could not formally exclude the malignant nature of the tumor. The challenging histological diagnosis and consequently the management of the patient are described.
