Myasthenia gravis with cutaneous polyarteritis nodosa

Cutaneous polyarteritis nodosa presents with typical cutaneous lesions of polyarteritis nodosa without visceral involvement at the time of diagnosis. We report a 32‐year‐old woman with a 12‐year history of myasthenia gravis under immunosuppressive treatment, who presented with tender, erythematous nodules 20 mm in diameter on her shins. A diagnosis of cutaneous polyarteritis nodosa was made, based on the clinical and histopathological findings. Myasthenia gravis, an antibody‐mediated disease, is occasionally accompanied by other autoimmune diseases, but we found no previous report in the literature associating it with polyarteritis nodosa.

Acquired localized elastolysis associated with varicose veins

Localized elastolysis refers to a group of heterogeneous conditions which includes cutis laxa. We report a form of localized and non‐inflammatory elastolysis evocative of cutis laxa, localized to the anteromedial aspect of the left thigh and knee, acquired at the age of 8 years and associated with unilateral adjacent venous dilatations appearing at the ape of 39 years.

Chikungunya associated with cutaneous ulcerations

Chikungunya is a viral infection commonly causing fever and arthralgias, sometimes accompanied with myalgias and rash. We report a 72‐year‐old woman presenting with a 3‐month history of painful cutaneous ulcerations on both legs, and discuss the cutaneous features associated with chikungunya.
