Primary Cutaneous Aspergillosis Presenting as a Multiloculated Cyst in the Hand

Invasive aspergillosis typically occurs in immunocompromised patients and results in fatal complications. Musculoskeletal involvement of aspergillosis is extremely rare, therefore, when it occurs, its diagnosis and treatment could be delayed. In this paper, we report a rare case of primary invasive aspergillosis with radiologic findings in a patient with rheumatoid arthritis. A 57-yearold woman presented a palpable mass on the right hand with a previous medical history of long-term use of immunosuppressive agents due to rheumatoid arthritis. Magnetic resonance imaging showed a multilobulated and multiloculated cystic lesion with an enhancing wall. The wall of the cystic lesion showed low signal intensity on T2 weighted images and intermediate to high signal intensity on T1 weighted images. The mass was confirmed as chronic granulomatous inflammation with multiple acute branching and septated fungal hyphae, consistent with invasive aspergillosis. When a superficial multicystic mass in the hand of especially immunocompromised patients is encountered, invasive aspergillosis should be included in the differential diagnosis, although it is rare.
