Dermatomyositis associated with angiotropic lymphoma

Summary We describe a 64‐year‐old man with dermatomyositis sine myositis who presented with unusual cutaneous plaques and nodules. Initial investigations failed to reveal evidence of malignancy. Eighteen months later he became systemically unwell and repeat biopsies from the nodules confirmed angiotropic T‐cell lymphoma. Cutaneous lymphoma is rarely reported with dermatomyositis and in the previously reported cases, mycosis fungoides was the variant seen. This is the first report of angiotropic T‐cell lymphoma associated with dermatomyositis.
