Question

a radiographic examination demonstrates uniform loss of joint space, erosive changes, and peri - articular osteopenia of joints throughout the hands bilaterally. which of the following conditions would not be part of the differential diagnosis? a rheumatoid arthritis b psoriatic arthritis c systemic lupus erythematosus

Explanation:

Rheumatoid arthritis, psoriatic arthritis, and systemic lupus erythematosus can all present with joint - space loss, erosive changes, and peri - articular osteopenia in the hands. However, the radiographic patterns and associated clinical features can help differentiate. But based on the general knowledge of these diseases' joint involvement, all of these are potential causes for the described radiographic findings. There may be a mis - framing of the question as all are possible in differential diagnosis in a general sense. But if we assume we need to pick one based on less typical joint involvement in some cases, systemic lupus erythematosus may be considered as it can have more variable joint manifestations compared to the more joint - centric rheumatoid and psoriatic arthritis.

Answer:

C. Systemic Lupus Erythematosus
