Muscle invasion by Basidiobolus haptosporus.

Invasion of muscle tissue in addition to dermis and subcutaneous tissue by Basidiobolus haptosporus is reported in a 40-year-old female housewife. This infection followed intramuscular injection injury of the right gluteal region. Oral KI cured the condition completely in 6 months. Intramuscular implantation of B. haptosporus by the injection needle is the probable mode of infection in this case. Possible blood vessel invasion seen in histology suggests the possibility of dissemination of the fungus.
