A rare case of Rhupus syndrome with Hashimoto's thyroiditis, associated adverse effect of drugs and incidental findings

Abstract

The term Rhupus is coded for the individuals who have rheumatoid like arthritis with erosions and fulfil the criteria for both rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Abnormal Th2 cell plays a central role in SLE while Th1 participate in RA. Thus the overlap of SLE and RA has a very low incidence (0.01%-0.2%) in patient with arthritis. This 40-year-old male patient presented with complains of severe multiple joint pain with progressive deformities, diminished vision from last 2 months, redness on back, headache and swelling over scalp. As this patient had history of severe trauma that was considered as a precipitating factor for ongoing chronic inflammatory disorder. Posterior subcapsular cataract was explained by prolong use of systemic steroid and rashes on the lower back due to sulfasalazine. Radioimaging study revealed arachnoid cyst and calcified projection arising from outer table of skull, which was kept under observation.
