ABSTRACT

The central nervous system melanoma represents 1% of all melanoma cases and only 10% of malignant melanomas in this site are primary. The first case of primary spinal melanoma was described in 1960 and to date, this lesion is extremely rare. We report a case of intraspinal melanoma in a young, pregnant woman, without associated risk factors. This clinical-pathological presentation has not been described before in the sources reviewed.
This clinical case is about a 23 year old woman with 28 weeks of pregnancy, admitted with dyspnea and flaccid paraparesis, the clinical history and medical examination were compatible with cauda equine syndrome. MRI identified a neoplasm at S1-S3. In surgery we found a deep black intraspinal tumor, infiltrating paravertebral structures, not viable for excision. The histopathological report confirmed malignant melanoma.
Conclusions: 2-5% of all primary melanomas do not come from skin. We present a pregnant patient with an intraspinal melanoma, in which a source could not be identified. The reviewed literature does not confirm a relationship between extra-cutaneous melanoma and pregnancy.
We reported a clinical situation with a very low incidence and we concluded the diagnosis of intraspinal melanoma as a probable primary malignancy.
