Black hairy tongue (BHT) is a benign, self-limiting, and usually asymptomatic condition, characterized by abnormally hypertrophied and elongated filiform papillae on the surface of the tongue. In this article, we present the case of a woman diagnosed with hebephrenic schizophrenia who developed BHT after using olanzapine to treat an acute episode of the disease. The temporal coincidence between the development of BHT and the increase in olanzapine dosage to 20 mg daily suggests a likely dose-dependent relationship, making this psychotropic drug the most probable cause of this condition.

Black hairy tongue, also known as , is a benign oral condition characterized by a dark discoloration and "hairy" appearance on the tongue's dorsal surface, resulting from elongated filiform papillae. This condition is associated with risk factors such as smoking, poor oral hygiene, and diabetes, which increase susceptibility to microbial colonization, particularly by species. Although commonly diagnosed by visual inspection, black hairy tongue is infrequently observed during endoscopic procedures.

We construct static and axially symmetric magnetically charged hairy black holes in the gravity-coupled Weinberg-Salam theory. Large black holes merge with the Reissner-Nordström (RN) family, while the small ones are extremal and support a hair in the form of a ring-shaped electroweak condensate carrying superconducting W currents and up to 22% of the total magnetic charge. The extremal solutions are asymptotically RN with a mass below the total charge, M<|Q|, due to the negative Zeeman energy of the condensate interacting with the black hole magnetic field.
