Case 110. Trichinellosis (mouse tongue)
Experimentally infected Trichinella spiralis in the mouse tongue
Key words : Trichinella spiralis, stichosome
Striated muscle cells contain 1 mm-sized, encapsulated foci with a coiled larva (HE). Inflammatory change is hardly observed.   The esophagus of the larva shows the stichosome, a chain of basophilic globular or columnar cells (HE). The stichosome is a common feature of Trichiurid helminth, such as T. trichuira, C. philippinensis and T. spiralis.
