A case of HILV1-associated adult T cell leukaemia/lymphoma (ATLL) in à 21-year olf African woman is reported. The patient presented with lymphomatous meningoradiculopathy. The usual clinical features of ATLL were absent. Lumbar MRI showed a pial enhancement by DTPA-gadolinium of the conus medullaris which extended to the proximal cauda equina. Under systemic chemotherapy coupled with intrathecal chemotherapy the patient progressively improved, and at the second MRI examination complete disappearance of the lumbar enhancement was observed. MRI of the brain using axial and coronal T2-weighted sequences detected multifocal lesions of high-intensity signal in the subcortical white matter. ATLL is unusual in people of African origin. The ATLL-strongyloïdes infestation association has previously been reported, suggesting that parasitic infestation may be an important co-factor leading to the development of ATLL.

The case of a 41 year old woman with amyloid myopathy is reported. Clinical involvement consisted of limb girdle muscle weakness, mild scapular muscle atrophy and dysphagia. In contrast with the published cases, abnormal firmness, pseudohypertrophy of the musculature and macroglossia were absent. Muscle biopsy showed endo- and perimysial amyloid deposits but also inflammatory infiltrates. Inflammatory cells typing was studied by immunocytochemical methods and revealed a predominant T-helper cell infiltration. Free kappa light chains were present in serum and urine. Serum immunoglobulin levels were reduced. Bone marrow examination revealed mild plasmocytosis without abnormal cells. Immunofluorescence and immunoperoxidase techniques for identification of the type of amyloid fibrils showed positivity with antisera to kappa light chains. A 4-year follow-up revealed a progressive worsening of muscle weakness despite immunosuppressive treatment. No malignant plasmocytosis occurred. The unusual inflammatory muscle infiltration observed in this case may suggest an associated polymyositis.
