A case of dermatomyositis with anti-TIF1γ antibodies revealing isolated para-aortic lymphadenopathy metastatic recurrence of endometrial cancer: A case report

Dermatomyositis is an inflammatory myopathy presenting with characteristic cutaneous eruption and may be accompanied by proximal muscle weakness. Dermatomyositis may represent a paraneoplastic syndrome in 15%–25% of cases and has rarely been associated with endometrial cancer. Herein, we report a case of dermatomyositis with anti-TIF1γ antibodies as the first clinical manifestation revealing isolated para-aortic lymphadenopathy metastatic recurrence of endometrial cancer after 4 years of remission. Interestingly, dermatomyositis rash completely resolved after lymphadenectomy. This case highlights the importance of early dermatomyositis diagnosis, thorough cancer screening, and that cancer treatment may, in some patients, foster dermatomyositis remission.
