以多處局部皮膚腫脹為初始表現並帶有AC-6（多核點）ANA形態病患之三年期追蹤

Three years follow up of a patient initially presented with multifocal swelling skin lesions with AC-6(multiple nuclear dots) ANA pattern

A 56-year-old female presented to our rheumatologic division with a 2-month history of progressive painful erythematous swelling of left upper arm. There were also faint left malar area erythema, polyarthralgia, localized nodular swelling sensation over her left lower abdomen, right thigh. The skin lesions got improving after prednisolone 10mg oral treatment within several days treated as panniculitis initially by clinical diagnosis. CT venography of left upper arm did not show venous thrombosis nor significant stenosis. ANA (anti-nuclear antibody) by IIFA (indirect immunofluorescence assay) method showed 1:640 in titer with multiple nuclear dots (Fig. 1A) pattern which was compatible with the AC-6 pattern defined by International Consensus on ANA patterns (ICAP).
