Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported. In leukemia patients, OHL is rarely encountered, and appears only after chemotherapy. We report a case of OHL which occurred as a presenting sign of acute myeloid leukemia (AML) in a previously healthy 15-year-old child. A 15-year-old boy presented with a whitish patch on the left lateral border of the tongue. The biopsy specimen revealed papillomatosis, hyperkeratosis, acanthosis and ballooning degeneration in the stratum spinosum. The patient was EBV seropositive, and PCR analysis of EBV DNA in the lesional tissue was positive. After the diagnosis of OHL in dermatologic department, the patient was referred to pediatrics due to the abnormal peripheral blood smear, and was diagnosed with AML.

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.

Background: Valproic acid (VPA) is used to treat various neurological and psychiatric conditions. While oral VPA can cause hair loss, topical application has shown potential for hair regeneration. This study aimed to develop and evaluate microemulsion (ME) formulations of VPA for enhanced transfollicular delivery.
