title: A case of multiple myeloma presenting as scalp swelling with intracranial extension.
abstract: Multiple myeloma is a malignant neoplasm of bone marrow affecting plasma cells. It is usually detected in skull bone with characteristic features of multiple punched-out lesions. Its presentation as a solitary scalp swelling with underlying skull bone erosion and intracranial extension is very rare. A 35-year-old female presented to us with complains of rapidly growing left-side scalp swelling with right-side paresis and simple partial seizure of right upper limb. Local examination, X-ray skull, CT scan, and MRI of brain were suggestive of a malignant lesion. Near total excision of lesion was done. Histopathological study was suggestive of plasmacytoma of skull. Bone marrow study further confirmed it as a case of multiple myeloma. Cases presenting with solitary osteolytic skull lesions, possibility of plasmacytoma, or multiple myeloma should be kept in mind.
