This is what I found:

Gottron’s papules.
Gottron’s papules, a pathognomonic sign of DM, are round, 0.2- to 1-cm, smooth, violaceous-to-red, flat-topped papules that occur over bony prominences, particularly the knuckles, along the sides of the fingers, and sometimes over the knees and elbows. There may be a slight scale and sometimes a thick psoriasiform scale. Telangiectasia may be present in the lesions. Lupus of the back of the hand usually spares the knuckles. Biopsy cannot distinguish the cutaneous lesions of DM from those of LE. Several lesions appear simultaneously any time during the course of the disease; they tend to remain fixed in position. Approximately 60% to 80% of DM patients have Gottron’s papules sometime during the course of the disease.

Clinical Dermatology, 5th ed.
