Match each clinical presentation to the most likely associated rheumatologic condition.
- A patient presenting with recurrent fetal loss, livedo reticularis, and a prolonged partial thromboplastin time (PTT) that fails to correct with normal plasma.Antiphospholipid syndrome
- A patient presenting with progressive proximal muscle weakness, periorbital edema with a purplish hue, and erythematous papules on the knuckles.Dermatomyositis
- A patient presenting with chronic lower back pain that improves with exercise, bilateral Achilles tendinitis, and acute unilateral anterior uveitis.Ankylosing spondylitis
- A patient presenting with severe xerophthalmia, xerostomia, accelerated dental caries, and episodic bilateral parotid gland swelling.Sjögren syndrome
- A patient presenting with daily spiking fevers, an evanescent salmon-colored maculopapular rash, and polyarthritis.Adult-onset Still disease
Answer
1 matches Antiphospholipid syndrome, 2 matches Dermatomyositis, 3 matches Ankylosing spondylitis, 4 matches Sjögren syndrome, and 5 matches Adult-onset Still disease.
Each clinical vignette provides highly specific, pathognomonic features that unambiguously link to a single rheumatologic diagnosis.
