Erythroderma is characterized by diffuse cutaneous erythema, which may be associated with multi-organ dysfunction. Erythrodermic psoriasis is the most common form of erythroderma. We describe a case of psoriatic erythroderma, which was successfully treated with a combination of apremilast and cyclosporine. Apremilast, a relatively safe drug, has no major side effects. A 33-year-old male came with chief complaints of redness and peeling of skin and itching all over the body since 3 years. Three years back, the patient developed severely itchy red lesions all over the body, which were associated with scaling. Biopsy of the lesion was suggestive of chronic plaque psoriasis progressing to erythroderma, and the patient was started on capsule cyclosporine 100 mg thrice daily with methotrexate 7.5 mg/week and was maintained on it for 4 months in a gradually tapering dose. One year later, he developed similar lesions and was started on capsule cyclosporine 100 mg thrice daily and acitretin 35 mg along with systemic steroids. Owing to the stopping of systemic steroids, there was an exacerbation of lesions. On cutaneous examination, the patient had a body surface involvement of more than 90% with diffuse erythema with multiple plaques with adherent scales present over the plaques over the trunk and extremities surmounted by multiple pustules [Figure 1]. Psoriasis Area and Severity Index (PASI) score was 39.8. A provisional diagnosis of unstable erythrodermic psoriasis with localized pustular psoriasis was made. On histopathology, elongation of rete ridges, suprapapillary thinning, dilated capillaries and parakeratosis, and spongiform pustules of Kogoj were seen, suggestive of psoriasis [Figure 2]. Biopsy from the pustule showed neutrophilic infiltration. Unstable erythrodermic psoriasis not responding to treatment with localised pustular psoriasis. Since the patient was already treated with multiple drugs, which failed to control the condition, we started the patient on the tablet apremilast along with cyclosporine 100 mg twice a day. The dose of apremilast was increased by 10 mg every week starting from 10 mg once a day. With this regimen, the patient did not experience any side effects. The dose was increased to 30 mg twice a day. The patient cleared dramatically over a period of 1 month. Cyclosporine was continued and tapered and maintained on 100 mg twice a week. The patient remains in the state of remission. PASI score after 1 month was 18 [Figure 3] and after 3 months was 4.2 [Figure 4].

| Discussion|| |
Apremilast, a phosphodiesterase-4 inhibitor, prevents the conversion of cyclic adenosine monophosphate (cAMP) to adenosine monophosphate. The resultant increase in cAMP levels modulates the production of proinflammatory and anti-inflammatory mediators. There is a decrease in the pro-inflammatory mediators such as tumour necrosis factor alpha, interleukin-12 and interleukin-23, interferon gamma, and nitric oxide synthase as well as upregulation of anti-inflammatory mediators such as interleukin-10. Studies on apremilast showed few adverse effects. The adverse effects include nausea, vomiting, headache, fatigue, upper respiratory tract infections, musculoskeletal pain, weight loss, mood swings, and suicidal tendencies. With gradual introduction of apremilast, no side effects were seen and the patient cooperated well.
Good safety profile and ease of oral administration without a need of laboratory monitoring makes apremilast a well-sought drug.
