BACKGROUND: Primary @entity5 of the central nervous system (CNS) are uncommon; @entity5701 in this region are extremely rare. Very few cases of amelanotic variation of primary @entity320 in the CNS were reported on. General guidelines or recommendations to establish this diagnosis do not exist. CASE REPORT: A sixty-year-old male Hispanic @entity1 presented with a 7-day history of @entity1183 and @entity1296 . Initial laboratory work-up and physical examination were inconclusive. Cerebral radiological imaging showed a @entity75 . Further work-up after clinical deterioration revealed an increase in the lesion size consistent with @entity548 and changes in T1WI. Biopsy and immunochemistry demonstrated the presence of @entity5701 in the CNS without evidence of another @entity75 . CONCLUSIONS: Primary @entity149 represents a challenge, clinically and diagnostically. Magnetic resonance imaging can be helpful in early stages. Final diagnosis is established with immunohistochemical testing. Physicians should be aware of the existence of this rare manifestation and difficulties faced while building this diagnosis.
