Background: Psoriatic arthritis was once diagnosed as Rheumatoid arthritis and was treated as such. Its significance as a separate arthritis has evolved after years of studies that revealed its pathogenesis, varied manifestations, and prognosis. It is one of the most common misdiagnosed inflammatory arthritis and requires its voice among the more known forms of arthritis. Material and Method: Cases coming to Rheumatology OPD with complaints of arthritis, dactylitis, and other associated presentations known in Psoriatic arthritis and its variants were collected. All the cases were extensively evaluated based on history, clinical findings, and investigations. Results: 6 cases were identified as having presentations of psoriatic arthritis. Patients came with manifestations like dactylitis, asymmetrical polyarthritis, oligoarthritis, SAPHO (synovitis, acne, pustulosis, hyperostosis and osteitis), axial involvement and psoriatic osteoarthritis knee. Conclusion: This case series illuminates the importance of suspecting psoriatic arthritis in every case of arthritis showing the above-mentioned features as they may not have a classical history of psoriasis always. These patients are often treated with seronegative arthritis or early osteoarthritis. Correct assessment and treatment can improve the outcome in such patients as they may be responsive to different sets of medications and have different prognoses than Rheumatoid arthritis.
