Peripheral T cell lymphoma presenting as dermatomyositis-like eruption.
BACKGROUND
There are several conditions reported to mimic the cutaneous manifestations of dermatomyositis, including lymphoproliferative disorders.


OBJECTIVE
This case report presents an unusual case of peripheral T cell lymphoma mimicking dermatomyositis and discusses the clinical and pathologic features that distinguish it from dermatomyositis.


RESULTS
A 62-year-old woman presented with a two-month history of a progressive painful cutaneous eruption and interstitial infiltrates on chest x-ray. Skin biopsy revealed peripheral T cell lymphoma. The diagnosis was confirmed by lung biopsy.


CONCLUSIONS
Although rare, a lymphoproliferative disorder must be included in the differential diagnosis of a cutaneous dermatomyositis-like eruption.
