Herein we report a complex case with heterozygosity for MEFV with atypical Adult Onset Still’s Disease (AOSD) in a 39-year-old Colombian woman, in her 3rd pregnancy trimester. At 33 weeks gestation, she presented with a sore throat, polyarthralgia, myalgia and pleuritic chest pains. She had an erythematous maculopapular rash thought to be pregnancy-related pruritic eruption. Earlier in pregnancy she had developed biopsy-confirmed reactive axillary lymphadenopathy. Past surgery included breast augmentation and bariatric surgery; family history unremarkable. Clinically she was tachycardic with wrist, metacarpophalangeal and proximal interphalangeal joint synovitis. She had bilateral pitting leg oedema which gradually spread to the abdomen, associated with worsening hypoalbuminaemia.
