External hirudiniasis is a skin infection caused by the parasitic flatworm Hirudinea. The flatworms attach themselves to the skin of their host, usually on the face, neck, or scalp, and feed on the host’s blood.
Diagnosis of external hirudiniasis typically involves a physical examination of the skin, in which the flatworms can be seen. In some cases, a skin biopsy may be performed to confirm the diagnosis.
External hirudiniasis can be difficult to differentiate from other skin conditions such as scabies, lice infestation, and tinea capitis.
Treatment of external hirudiniasis typically involves the topical application of a topical antifungal cream or lotion. In some cases, oral antifungal medications may be prescribed. In addition, it is important to keep the skin clean and dry to prevent reinfection.
The prognosis for external hirudiniasis is generally good, as the condition is usually easily treated. However, if left untreated, it can lead to secondary infections and other skin problems.
