[1] Combinations of nodules affecting the head, neck, and periarticular (particularly interphalangeal) joints, as well as linearly arranged ivory white papules over erythematous indurated skin, are examples of cutaneous manifestations.

[2] Myalgia, pyrexia, and muscle exhaustion are examples of mild inflammatory symptoms that typically appear at the same time as cutaneous lesions.

Lesions lack extracutaneous involvement and are linked to absent to mild inflammatory symptoms like arthralgia, fever, weakness, and muscle tenderness.

[4][5] Some authors speculated that it might be because of an infection or inflammation that stimulates the antigenic response continuously at the level of initial fibroblast and mucin production.

[6][7] MRI findings of myositis and subcutaneous tissue edema have been identified along with other abnormalities such as elevated aldolase levels, lymphocytosis, accelerated erythrocyte sedimentation rate, and antibodies against Bartonella.
