[Dermatomyositis with cutaneous necrosis revealing a fallopian tube carcinoma].

INTRODUCTION

Adult dermatomyositis is a rare inflammatory myopathy associated with typical cutaneous lesions and an increased incidence of internal malignancies, notably cancers of the female genital tract. Nevertheless, fallopian tube carcinoma is exceptionally associated with dermatomyositis.

EXEGESIS: We report an unusual case of dermatomyositis because of cutaneous necrosis revealing a cancer of the fallopian tube.

CONCLUSION

Predictive factors of cancer can improve prognosis of dermatomyositis due to earlier diagnosis of associated cancer. In our observation as in literature review, cutaneous necrosis lesions are highly predictive of an associated neoplasia even as rare as a fallopian tube carcinoma.
