There are mainly the following clinical situations when black things are pulled out of the ear: First, some patients have cerumen in the ear canal, which contains a relatively high level of oil, and the oil may turn black after oxidation, also seen in patients with particularly long storage time of cerumen in the ear canal. Some patients have fungal infections in the ear canal, and the fungal masses may appear as black-brown, which is very common clinically, and this change can usually be found by doing fungal smear examination of secretions, and some patients can also see the fungal mycelium growth in the ear canal. Third, the patient had previous injury to the external ear canal or other places, and there was bleeding at that time, and then the blood coagulated and became a black blood clot. Fourth, some patients, such as those who work in a dirty environment, have cinder or soot-like things inside their ears, which can manifest as a black foreign body manifestation when they pull out their ears for a long time.
