Cryptococcal cellulitis in a patient on prednisone monotherapy for myasthenia gravis.

The development of cutaneous cryptococcosis is extremely rare in the human immunodeficiency virus-negative population. The cutaneous manifestations vary greatly, with the rarest presenting as cellulitis. We report a unique case of a 64-year-old woman who had been on prednisone monotherapy for the treatment of myasthenia gravis and subsequently developed cryptococcal cellulitis.
