Meningeal melanomatosis is an aggressive version of meningeal melanocytosis and one of the recognized primary melanocytic tumors of the CNS. It represents proliferation of melanocytic cells within the subarachnoid space 1. There is a strong association with cutaneous melanocytic lesions, in which case it is known as neurocutaneous syndrome 3 Meningeal melanomatosis following discontinuation of dabrafenib: implications for the maintenance of long-term complete remission.

Primary diffuse meningeal melanomatosis is a rare variant of malignant melanoma of the CNS that seems to arise directly from melanocytes within the leptomeninges (1). Despite the use of CT, contrast-enhanced MR imaging, and CSF cytology, the disease can be difficult to recognize . Although most commonly seen in patients with disseminated disease, in a small percentage of patients, it may be the initial manifestation of cancer or even primitive in origin. In the absence Background Primary diffuse meningeal melanomatosis is a rare form of CNS melanoma arising from the melanocytes within the leptomeningies with very poor prognosis.

The metastatic tumor cells grow either attached to the pia mater covering the brain and spinal cord or floating unattached to the subarachnoid space Summary: Neurocutaneous melanosis is a rare congenital syndrome characterized by large or multiple congenital melanocytic nevi and benign or malignant pigment cell tumors of the leptomeninges. The prognosis is extremely poor for symptomatic patients, even in the absence of malignant melanoma.

Melanocytoma and meningeal melanocytosis, are similar but different lesions.. Meningeal melanomatosis is an extra-axial well-encapsulated malignant tumour with diffuse meningeal growth and dark coloration (due to high melanin contents), while meningeal melanocytoma is the focalized benign variant. Melanocytic tumors may be secondary to melanoma or be histologically benign, however, their.
Meningeal melanomatosis, on the other hand, is a malignant proliferation of melanoma cells that spread diffusely within the CSF, but also extend into Virchow-Robin spaces and are capable of invading CNS parenchyma Rationale: Primary melanocytic tumors of central nerve system (CNS) are rare, primary diffuse leptomeningeal melanomatosis (PDLM), a subtype of malignant melanomas of CNS, is extremely rare,especially in pediatrics. As the clinical manifestation of PDLM is not characteristic, It is often misdiagnosed as tubercular meningitis and hemorrhage
Meningeal melanomatosis has a separate ICD-O-3 code, but is also a very rare form of melanoma. Answer This is a single primary coded to the site of the original melanoma. The brain and meninges are both metastatic sites. The MP/H Rules do not apply to metastases. This case was sent to the melanoma physician specialists Meningeal melanomatosis and parenchymal brain metastases were diagnosed. Extracerebral metastases were excluded. Reinduction of dabrafenib, combined with trametinib, led to the rapid relief of the neurological symptoms, and a partial remission was confirmed radiologically. Unfortunately, the response was not maintained and the patient died 9.

A comprehensive periodontal examination around teeth was accomplished before periodontal and implant treatment Primary Diffuse Meningeal Melanomatosis. Primary diffuse meningeal melanomatosis is a particularly aggressive form of primary intracranial melanoma.

Neurocutaneous melanosis (NCM) is a sporadic condition characterised by congenital melanocytic nevi and melanocytic thickening of the leptomeninges.

Meningeal Neoplasm. A benign or malignant neoplasm that affects the meninges. The majority of the neoplasms arise from meningothelial cells and are called meningiomas. Non-meningothelial cell neoplasms include mesenchymal, non-meningothelial tumors, hemangiopericytomas, and melanocytic lesions.

Primary leptomeningeal melanomatosis. Primary leptomeningeal melanomatosis is a rare, aggressive neoplasm of the CNS that arises from melanocytes within the leptomeninges and carries a poor prognosis. It is also referred to as a meningeal variant of primary malignant melanoma Leptomeningeal melanomas may be visualized on CT and MRI scans and, in cases of spinal melanomatosis, on myelogram. However, CT scans may fail to show the tumor (1, 13, 56) because of surface and/or bone interface. Moreover, in cases of spinal meningeal melanomatosis, the myelogram may mimic arachnoiditis Melanocytes are found in various places in the body, including in the meninges, the membranes that cover the brain.
