“…[6910] Cystic melanotic lesions reported are primarily either melanoma or schwannoma that have undergone cystic degeneration or hemorrhagic transformation. [1–311–13] Surgical excision is the accepted treatment of choice in most cases, except for recurrent and malignant lesions. [1415] These have higher risk of malignant transformation and metastasis; hence patients have to be followed-up periodically for recurrence of symptoms and also look out for other complaints suggestive of metastasis.…”

Till date, 85 cases of melanotic schwannoma and 11 cases of spinal root melanoma have been reported in literature. We are reporting a case of a 45-year-old lady who presented with primary low back pain, and magnetic resonance imaging of lumbo-sacral spine showed at left L5-S1 foraminal lesion extending to the para-spinal compartment. Hemi-laminectomy, facetectomy, and excision of the lesion were done. It was primarily a cystic lesion with attachment to the exiting spinal nerve root. Histopathology of the cyst wall showed a fibro-collagenous stroma with no specific cell lining containing melanin pigment suggestive of a melanotic cyst. The patient was completely relieved of the back pain, and had no recurrence over a follow-up period of one and half years. This case is probably the first reported predominantly cystic, pigmented lesion, affecting the spinal root.

“…Kasnatikul, in 1989, had reported a case of spinal melanotic arachnoid cyst, which was characterized by a melanotic cyst, lined with a cuboidal epithelium which was in continuation with the leptomeninges [9]. Cystic melanotic lesions reported are primarily either melanoma or schwannoma that have undergone cystic degeneration or hemorrhagic transformation [4,[15][16][17][18][19][20]. These tumors are more often associated with neurocutaneous syndromes such as neurofibromatosis as opposed to this reported case, where there were no neurocutaneous stigmata.…”

Primary spinal melanoma is a rare lesion, which occurs throughout the cranial and spinal regions, however, is primarily observed in the cervical spine. we report on a case of an uncommon localization of primary malignant extra-dual and intradural extra-medullary melanoma of the 8th cervical spinal nerve root which developed in a 27-year man who complained of pain in the lower cervical spine, with left upper extremity tingling sensation. Neuro-radiological features of this extra-Dural mass were suggestive of a nerve sheath tumor. Magnetic Resonance Imaging (MRI) of cervical spine showed a lesion in extra-Dural and intradural extra-medullary mass who were suggestive of a nerve sheath tumor, but the histological examination confirmed the histological nature of primary malignant extra-Dural and intradural extra-medullary melanoma. The resection was complete using a standard posterior midline approach, which was followed by chemotherapy. and the course has been satisfactory after 06 months follow-up. Subsequent to the surgery, the patient was discharged with improved motor capacity and a follow up MRI scan showed no recurrence after six months. The present study demonstrates that it is critical for neurosurgeons to focus on increasing the accuracy of initial diagnoses in order to make informed decisions regarding the requirement for surgical resection. There are no evidence-based guidelines regarding primary spinal melanoma, for example specific incidence, treatment or prognosis guidelines.

Cystic renal melanoma: CT/ultrasound correlation

Abstract: A new computed tomographic and sonographic appearance of renal metastatic melanoma is described. Bilateral cystic masses with thick walls, many with mural nodules, were noted. Sonography also demonstrated complex echopenic masses with irregularly thickened walls and mural nodules.
