A 34-year-old Caucasian woman is presented with a circular hemorrhagic lesion located on the soft palate and caused by fellatio. The lesion consisted of erythema, petechiae, dilated blood vessels and vesicles. It healed in a few days. No evidence of the major clinical alternatives such as thrombocytopenia, venereal disease, candida infection or pathomimia were found. Injuries due to fellatio must be considered as an etiological factor to hemorrhagic changes of the oral mucosa, and with a positive history, patients can be spared from other investigations.
