Answer

Various methods attempt to improve the appearance of the nodular localized cutaneous amyloidosis lesions, including topical and intralesional corticosteroids, cryotherapy, dermabrasion, [21] shaving, curettage and electrodesiccation, carbon dioxide laser, [22, 23, 24] and pulsed dye laser. [25] However, lesions frequently recur after treatment. Topical and intralesional corticosteroids and cryotherapy usually are not helpful. One attempt at cryotherapy produced pinpoint bleeding. Recently, a solitary report has described successful treatment with cyclophosphamide in a patient with both CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia) and Sjögren syndrome. [26]  One patient responded to intralesional methotrexate. [27]

Rarely, patients with nodular localized cutaneous amyloidosis develop systemic amyloidosis or multiple myeloma years later, suggesting the need for follow-up care.
