Trichomonas vaginalis is generally not dangerous and most classical adult forms of Trichomonas vaginalis may heal spontaneously within 2 to 3 years.
Patients with this type have lesions that start as small, limited follicular keratoses that gradually fuse into large patches, some of which may even spread throughout the body. It then enters a stable phase and after 2 to 3 years enters a process of natural regression and does not usually recur after self-healing.
However, the familial type of hair red furunculosis does not usually heal on its own and often recurs and remains with it for life, but treatment is carried out promptly and does not cause serious harm.
