Abstract:
Myospherulosis is an unusual foreign-body reaction occurring in tissues exposed to petrolatum-based products. Histopathologically this disorder is characterized by the presence of large and small tissue spaces containing amorphous debris and peculiar sac-like structures enclosing numerous brown spherical bodies. A rare case of myospherulosis of the middle ear and mastoid is presented and the literature is reviewed.
