ABSTRACT
Raynaud's phenomenon (RP) presents as acral skin pallor, cyanosis, and erythema, usually after cold exposure or emotional stress. Symptoms of RP affect 3-5% of the general population, with the incidence four times higher in women than in men. Paraneoplastic RP is extremely rare and is thought to involve plasma hyperviscosity and blood hypercoagulability, which are present in patients with malignant diseases. Paraneoplastic RP often presents abruptly and, besides changes in skin color, it includes erosions, ulcerations, and necrosis, resulting in severe pain. We present a case of a 62-year-old female patient who suddenly developed symptoms of RP, characterized by periodic skin pallor without erosions or associated pain in all fingers, lasting 10-15 minutes after cold exposure. She was diagnosed with uveal melanoma three months prior and was also in a 14-year remission from invasive ductal carcinoma. Investigations confirmed positive antinuclear antibodies (ANA) with PCNA (proliferating cell nuclear antigen) and myositis-specific antibodies including anti-Jo, anti-mitochondrial antibody (AMA-M2), and anti-benzylpenicilloyl antibody (BPO).
