A 34-year-old man with psoriatic arthritis (PsA) and refractory anemia of chronic disease treated with glucocorticoids for 1 year returned with florid cutaneous lesions and fever of 2 weeks after abruptly stopping glucocorticoids. Physical examination revealed pallor, erythroderma, and widespread pink droplet-like skin lesions with overlying paper-thin plaques involving 50% of face, >90% of the trunk, limbs, palms, and soles [Figure 1], suggestive of unstable psoriasis. Healed sequelae of previous cutaneous lesions and onycholysis with subungual hyperkeratosis of toenails were present. Musculoskeletal examination revealed arthritis of the ankle, small hand joints, and swan-neck deformity, with the restricted terminal extension of the elbows and knees. He tested negative for HIV.

While PsA mostly manifests classic chronic cutaneous plaque psoriasis, unstable psoriasis is seen in association with abrupt withdrawal of steroids and DMARDS, and infections., Unstable psoriasis represents an exacerbation of psoriatic disease and initially mimics guttate forms, presenting with diffuse small droplet-like papules. These lesions progress within days to weeks to enlarge or coalesce into larger plaques or evolve into pustular lesions or erythroderma. PsA flares in HIV patients can present with an admixture of guttate and plaque types of lesions. This has particular implications in countries like India, where patient care is suboptimal due to the low affordability of treatment and rampant systemic corticosteroid abuse. As such, one can expect to encounter more cases with a similar picture.
