Inclusion body myositis (IBM) is a late-onset myopathy that manifests as distinct muscle weakness in the quadriceps, finger flexors, and ankle dorsiflexors. T-cell large granular lymphocyte (T-LGL) leukemia is a late-onset clonal disorder of CD8+ cytotoxic T-cells that is often accompanied by autoimmune diseases. To date, the association between IBM and T-LGL leukemia has been infrequently reported. Here, we report a case of a patient with T-LGL leukemia who developed IBM, along with in-depth laboratory, electrophysiological, and pathologic findings.

Adrenoleukodystrophy (ALD) is the most common peroxisomal disorder caused by mutations in the gene, ABCD1, causing abnormal accumulation of very-long-chain fatty acids in the nervous system and adrenal glands. There are various clinical manifestations of ALD. Here we report a 47-year-old male with adrenomyeloneuropathy with cerebral involvement who exhibited progressive gait disturbance and cognitive impairment. A novel frameshift variant (c.95del [p.Val32Alafs*36]) in exon 1 of ABCD1 was identified. This report provides additional information regarding the various clinical characteristics of ALD.
