Unveiling multisystem involvement in polyarthritis: A case of rheumatoid arthritis with nutritional anemia and eczema

Rheumatoid Arthritis (RA) is an autoimmune systemic disorder that can present with multisystem involvement. A 20-year-old female presented with fever, multiple joint pains, morning stiffness, and fatigue. Laboratory findings showed elevated Rheumatoid Factor and Anti-CCP antibodies confirming RA, along with iron deficiency anemia and dermatological manifestations—tinea cruris and eczema. She was treated with methotrexate, corticosteroids, antifungals, and iron supplementation, showing gradual clinical improvement. This case highlights the interconnection between autoimmune inflammation, nutritional deficiency, and skin disorders, emphasizing the need for comprehensive and multidisciplinary management in patients with rheumatoid arthritis.
