Pityriasis rubra pilaris (PRP) is a rare, chronic papulosquamous disorder with limited treatment options in pediatric patients. We report the case of a 9-year-old boy with juvenile PRP (type III), who achieved complete disease remission after treatment with secukinumab, an IL-17A inhibitor, following initial therapeutic resistance to topical agents. This case, notable for PRP onset after erythema infectiosum, highlights a potential infectious trigger and the therapeutic benefit of targeting the IL-17A pathway in PRP. Our findings support further exploration of secukinumab as a treatment option for juvenile PRP.

Rheumatologists and other nondermatologists often encounter patients with psoriatic arthritis (PsA) who present with cutaneous diseases that mimic psoriasis (PsO). Cutaneous disorders including tinea, seborrheic dermatitis, eczema, pityriasis rubra pilaris, syphilis, or cutaneous lymphoma are commonly mistaken for PsO. It is crucial for rheumatologists and other nondermatologists to recognize alternative conditions and to consider referral to dermatology when skin disease is not responding to therapy.

Toxic shock syndrome (TSS) is a serious, often fatal disease, rarely occurring in dogs via infection with and . The development of TSS is mainly dependent on the presence of bacterial toxins recognized to be potent superantigens causing the release of massive amounts of host inflammatory cytokines, notably TNF-α, progressing to high fever, hypotension, haemoconcentration, thrombosis and neutrophil and endothelial activation with multiple organ failure. Rarely, TSS is associated with erythematous and exfoliative dermatitis progressing to ulceration with extremely extensive dermo-epidermal detachment, which is often very painful.
