Key Clinical Message:
Tickborne diseases have become the threats to the health of people worldwide, accounting for nearly 80% patients with vectorborne diseases in the United States. Early diagnosis and proper treatment play a significant role in the management. Close contacts should be screened for delayed symptoms associated with tickborne diseases.
Abstract:
This study describes a rare case of a 72-year-old Chinese man presented with a 5-day history of painful nodules on the perianal region, indicating tick bite. Tickborne diseases become the threats to the health of people worldwide. Untreated cases may result in several serious inflammatory complications. Manual removal of ticks with fine forceps is effective for preventing the transmission of tickborne infections. People (who have been bitten by a tick) and close contacts should be screened for delayed symptoms associated with tickborne diseases.
