Black hairy tongue after chemotherapy for malignant brain tumors.

Black hairy tongue (BHT) developed in five patients (2.6%) among 192 patients undergoing chemotherapy for malignant brain tumors. Three patients with a history of diabetes mellitus developed BHT within 10 days after the initiation of chemotherapy. The other two patients suffered more than 100 days after induction and lymphopenia of grade 3 or worse developed for more than 20 days, which was not observed in the three patients with diabetes. We found that BHT could develop after chemotherapy for malignant brain tumors. Patients with diabetes mellitus presented early after chemotherapy, while patients with longstanding severe lymphopenia presented in late phase.

Two Cases of Children With Black Hairy Tongue and Tooth Discoloration Caused by Antibacterial Agents.

Black hairy tongue (BHT) is a lesion in which the filiform papillae of the tongue are significantly extended by hyperkeratosis, thereby giving the tongue a hairy appearance. Here, we report two rare cases of children with BHT and tooth discoloration caused by antimicrobial agents. Case 1: A four-year-old female patient received intravenous linezolid after spinal surgery, and BHT developed on day eight of treatment. Subsequently, the patient developed teeth discoloration. Linezolid was continually administered for 50 days, and BHT and teeth discoloration improved 10 days after the end of linezolid treatment. Case 2: A two-year-old male patient with a brain abscess received intravenous meropenem and vancomycin. On the fourth day of treatment, BHT developed, and teeth discoloration was subsequently observed. Antibiotic therapy was continued for 82 days, and BHT and tooth discoloration improved 20 days after the treatment was discontinued.

Two Cases of Superficial Fungal Infection Caused by Non-Albicans Candida Species Manifest Greenish-black Discoloration.

The clinical manifestation of superficial candidiasis varies depending on the infectious sites and causative Candida species that brings a great challenge to diagnose or treat without mycological or pathological evidence in clinical settings. Oral mucosal candidiasis and onychomycosis are most common types of superficial candidiasis. Typically, oral mucosal candidiasis manifests as white or erythematous thrush coated on the tongue and other interior oral cavity; and onychomycosis caused by Candida spp. presents with thick, fragile, or cracked fingernails or toenails in yellow or white discoloration. Here, we report one case of patient with a black hairy tongue caused by Candida tropicalis and one case of greenish discolored onychomycosis caused by Candida parapsilosis. The cases of superficial candidiasis with the same discolored lesions were searched in literature and compared with our cases in clinical manifestation, causative pathogen and treatment. These cases highlight the importance of mycological diagnosis for identifying non-Candida albicans Candida species (NCAC) in superficial infections to guide an effective therapy.

A Case Report of a Co-Amoxiclav-Induced Black Hairy Tongue.

A black hairy tongue is a benign, self-limiting condition characterized by the discolouration of the tongue due to defective desquamation. Clinical presentation varies, with most cases being asymptomatic although aesthetically unpleasant to the patient. Prevalence varies geographically, ranging from 0.6% to 11.3%. It can be triggered by various factors such as medications, smoking, alcohol, poor oral hygiene, or even underlying systemic conditions such as malignancy. Several antibiotics such as doxycycline, erythromycin, amoxicillin-clavulanate, metronidazole, and piperacillin-tazobactam, have been reported to cause black hairy tongues. Onset can range from a few weeks to as long as five weeks. Diagnosis relies on clinical assessment with a good history and visual examination. Definitive treatment remains unclear, but the condition typically improves by identifying and discontinuing the causative agent and maintaining adequate oral hygiene. Complications are rare, and the prognosis is excellent. This case report aims to raise awareness of the association between the black hairy tongue and co-amoxiclav, which may impose additional burdens on patients, healthcare providers, and the health system if failed to be recognized and treated appropriately.

Drug-induced Tongue Disorders: A Comprehensive Literature Review.

BACKGROUND: Some drugs cause tongue disorders as adverse effects. Most of the druginduced tongue disorders are benign and will resolve after drug discontinuation. However, the changes in the color or appearance of the tongue may frighten patients and decrease compliance with drug therapy. OBJECTIVE: To review the literature to find all reports of drug-induced tongue disorders, their presentation, management, and outcome of patients Methods: The search was conducted in Google Scholar and PubMed using key words "ageusia," "burning tongue," "coated tongue," "drug-induced taste disturbances," "dysgeusia," "glossitis," "glossodynia," "hairy tongue," "hypogeusia," "stomatodynia," "stomatopyrosis," "swollen tongue" "tongue discoloration," "tongue irritation," "tongue numbness, "tongue oedema," and "tongue ulcer. All reports that were published from 1980 to 2022 in the English language were included in the study. Reports that were not in English language but had English abstracts with adequate data for extraction were also included. RESULTS: A total of 208 case reports and case series were included. The most reported drug classes were antineoplastic and immunomodulating agents and anti-infectives for systemic use, and the most common tongue disorders were tongue discoloration and black hairy tongue. Having good oral hygiene and discontinuing the offending drug could manage and resolve the problem. CONCLUSION: Drug-induced tongue disorders are not rare adverse drug reactions. They are benign in most cases, and withholding offending agents results in significant improvement or complete resolution of tongue lesions.

Linezolid-induced black hairy tongue in a patient treated for idiopathic granulomatous mastitis: a case report.

Linezolid-induced black hairy tongue (BHT) is a highly scarce adverse event of linezolid therapy. To date, there are very few reported cases in contemporary literature. The onset and mechanism of BHT are also not well understood. Case report: In this article, the authors report a case of BHT in a 28-year-old female following 5 days of therapy with linezolid. The patient recovered well within few days of discontinuation of the drug and maintaining oral hygeine. Patient reassurance and counselling was integral to the management. Discussion and conclusion: This case report and review depict a rare adverse effect of linezolid and discuss its clinical implications aiding healthcare professionals in an early diagnosis and cromulent management strategy. The authors also present a compilation of previously reported literature on linezolid-induced BHT to support the discussion.

Black hairy tongue after alprazolam intake.

Key Clinical Message: A 31-year-old female with a diagnosis of bipolar disorder developed black hairy tongue after alprazolam therapy. Her symptom resolved 10 days after the cessation of alprazolam. Abstract: Alprazolam is a widely used antidepressant and antianxiety drug. Mild to moderate side effect of alprazolam was commonly seen, including lethargy, dizziness, headache, dry mouth, nausea, fatigue, constipation, and blurred vision. In this case, we reported a patient developed black hairy tongue after alprazolam intake, and her symptom resolved after 10-day discontinuation of alprazolam. This rare adverse event should be of concern to clinicians. This is the first paper to report an alprazolam-induced BHT. This rare side effect of alprazolam should be concern of clinicians; we hope our report will promote the understand of BHT and acknowledge clinicians of this rare side effect of alprazolam.

Black Tongue: A Rare Presentation of Rhupus Syndrome.

Black tongue is a benign condition typically caused by the overgrowth of dead skin cells, resulting in elongated papillae and a hairy appearance. Other factors contributing to this condition include inadequate oral hygiene, a soft diet, and staining from bacteria, food, yeast, and other substances. It may cause symptoms such as bad breath, a metallic taste in the mouth, and an unsightly black hairy-looking tongue. Here, we present a case of a 30-year-old female who came to our hospital complaining of bad breath and a black tongue for the past month. She had previously taken antibiotics at the primary care medical center, but there was no improvement. We then prescribed her fluconazole, an antifungal medication, for the next two weeks. After two weeks, she returned with a slightly improved tongue color. Further investigation revealed a history of abortion and mild intermittent joint pains, for which she had been self-medicating with over-the-counter acetaminophen. A complete work-up led to the discovery of positive anti-cyclic citrullinated peptide (anti-CCP) antibodies, anti-double-stranded (anti-DS) DNA antibodies, and ANA, leading to the diagnosis of Rhupus Syndrome, an overlap of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA).

Oral Bacteria Dysbiosis in Patients with Linezolid-Induced Black Hairy Tongue: A Case Series.

Linezolid-induced black hairy tongue is a self-limiting benign disease that is rare. Here, we report three patients who developed black hairy tongue after linezolid treatment. The severe dysbiosis of oral bacterial communities was observed in all these patients. Proteobacteria was the most prevalent phylum (over 90%) at the black tongue stage. Furthermore, the dramatic oral bacterial alteration took a long time to reverse after the BHT resolved.

Tetracycline-induced black hairy tongue.

A blackish discolouration on the central part of the dorsal tongue in the front of the circumvallate papillae.

Antibiotic-induced black hairy tongue: two case reports and a review of the literature.

Black hairy tongue (BHT) is characterized by a discolored, hairy tongue. We herein report two cases of BHT associated with antibacterial agents and review previous cases. In Case 1, a 17-year-old girl with a central neurocytoma was administered intravenous piperacillin-tazobactam for postoperative infection, and BHT developed 12 days later. Her symptoms resolved 8 days after she discontinued the piperacillin-tazobactam and brushed her tongue three times daily. In Case 2, a 65-year-old man was administered intravenous piperacillin-tazobactam and levofloxacin to treat multidrug-resistant Pseudomonas aeruginosa, and BHT developed 15 days later. The piperacillin-tazobactam was discontinued and the patient brushed his tongue, and the discoloration gradually subsided thereafter. However, the BHT reappeared after linezolid treatment. The patient had adverse drug reactions to both the piperacillin-tazobactam and linezolid treatments. The BHT might have been related to antibiotic use in both cases. We identified 19 cases of antibiotic-related BHT in a literature search, but none were related to piperacillin-tazobactam use. In all cases, symptoms resolved after discontinuation of the drug and brushing of the tongue. BHT may be a rare adverse effect of antibiotics. Treatment strategies include removal of the causative agents, mechanical debridement, and good oral hygiene.

Black brown discoloration and hairy tongue - A rare linezolid side effect.

INTRODUCTION: Linezolid was approved for clinical use for methicillin resistant Staphylococcus aureus and vancomycin-resistant Enterococci. Additionally it is used in the management of drug resistant tuberculosis. It is well-tolerated however bone marrow suppression and neuropathies may occur in patients taking this antibiotic for more than 2 weeks. Black discoloration and black hairy tongue (BHT) due to linezolid is rarely reported. We report two cases of BHT. CASE REPORTS: Two patients of drug resistant pulmonary tuberculosis developed benign hairy tongue with linezolid 600mg per day. In both the cases black colored/hairy tongue was reported within 2-3 weeks of linezolid treatment. Both patients improved after withdrawal of linezolid. Subsequent reintroduction of linezolid with good oral hygiene was well tolerated and both patients completed the treatment of 2 years duration without any recurrence. CONCLUSION: Black discoloration and BHT is a rare but transient adverse reaction with linezolid. Reintroduction of linezolid with good oral hygiene is well tolerated.

Lengua vellosa negra en lactante

RESUMEN Introducción: La lengua vellosa negra es un trastorno benigno adquirido, de presentación inusual en pediatría. Consiste en una glositis benigna caracterizada por una hipertrofia de las papilas filiformes linguales, con aumento de su queratinización, lo cual condiciona que la superficie adquiera un aspecto velloso con un color que varía de pardo negruzco a negro, debido a la presencia de microorganismos productores de sustancias cromógenas. Objetivo: Describir las principales características de esta entidad y revisar los conceptos más actuales. Presentación del caso: Lactante de 10 meses que es llevado a consulta al notar la madre que el niño presentaba una lengua de color negro, con antecedentes de haber sido tratado con cefalexina debido a un impétigo contagioso 10 días antes. El examen físico mostró un aumento de volumen de las papilas filiformes linguales, posiblemente vinculada al uso del antibiótico, asociada a una defectuosa limpieza de la lengua. En el estudio microbiológico se aisló Cándida albicans, que se consideró como hallazgo concomitante. El tratamiento consistió en medidas de limpieza de la lengua con buena respuesta. Conclusiones: La lengua vellosa negra es una enfermedad autolimitada rara en lactantes, de diagnóstico clínico y buen pronóstico. El tratamiento debe ir encaminado al empleo de medidas higiénicas, como terapéutica de primera línea. El tratamiento antifúngico por lo general es innecesario. Hasta donde conocemos, este es el primer caso en Cuba, documentado en la literatura médica.

ABSTRACT Introduction: Black hairy tongue is an acquired benign disorder, of unusual presentation in pediatrics. It consists of a benign glossitis characterized by a hypertrophy of the lingual filiform papillae, with increased keratinization, which conditions that the surface acquires a hairy appearance with a color that varies from blackish brown to black, due to the presence of microorganisms that produce chromogenic substances. Objective: Describe the main characteristics of this entity and review the most current concepts. Case Presentation: A 10-month-old infant who is taken to the consultation when the mother notices that the child had a black tongue, with a history of having been treated with cephalexin due to a contagious impetigo 10 days before. Physical examination showed an increase in volume of the lingual filiform papillae, possibly linked to the use of the antibiotic, associated with a defective cleaning of the tongue. In the microbiological study, Candida albicans was isolated, which was considered as a concomitant finding. The treatment consisted of tongue cleaning measures with good response. Conclusions: Black hairy tongue is a rare self-limiting disease in infants, with a clinical diagnosis and a good prognosis. Treatment should be aimed at the use of hygienic measures, as first-line therapy. Antifungal treatment is usually unnecessary. As far as we know, this is the first case in Cuba, documented in the medical literature.

Black hairy tongue with a fixed dose combination of olanzapine and fluoxetine.

Black hairy tongue (BHT) is a benign disease characterized by elongated filiform lingual papillae, with a carpet-like appearance of the dorsum of the tongue. It is has been reported to occur with a prevalence ranging from 0.6% to 11.3%. Although its etiology is not fully understood, BHT may be triggered by smoking, excessive coffee or black tea drinking, poor oral hygiene, trigeminal neuralgia, general debilitation, dry mouth as well as certain drugs. We present here a case of a patient with psychosis, depression, and benign prostatic hyperplasia, who developed BHT following treatment with a fixed dose combination (FDC) of olanzapine and fluoxetine and recovered within 3 months after withdrawal of treatment with FDC.

Black hairy tongue in a patient with amyotrophic lateral sclerosis.

Black hairy tongue (BHT) is a condition characterized by the elongation of filiform papillae associated with a marked discoloration, from yellowish-brown to black, and a thick lingual coating. BHT is usually observed in the elderly and in patients with limited self-sufficiency, as a consequence of poor oral hygiene. In this perspective, the patients affected by amyotrophic lateral sclerosis (ALS) represent a high-risk category for the occurrence of BHT. The fast and inexorable loss of their self-sufficiency due to progressive muscle atrophy as well as the impropriate education of healthcare assistants have demonstrated to have significant reflection on the maintenance of an adequate standard of oral hygiene. This paper firstly described a case of BHT in a patient affected by ALS. A case of BHT in a patient (Caucasic, male, 63 years old) affected by ALS was described. The primary goal of the work was to teach and motivate the patient to the use of the tongue cleaner in association with the local application of chlorexidine 0.20%. Furthermore, in order to support the patient with accurate domiciliary oral hygiene, a proper training for his health-care assistant was provided. The maintenance of the oral health of ALS patient is fundamental to prevent systemic complications that could jeopardize the already fragile physical balance of these patients. The dedicated monitoring by a dentist or a dental hygienist would seem essential in order to achieve this objective.

Lengua negra pilosa asociada a carcinoma escamocelular de esófago / Black hairy tongue associated with squamous cell carcinoma of the esophagus

Resumen La lengua negra pilosa (LNP) es una alteración benigna caracterizada por coloración oscura e hipertrofia con hiperqueratosis en las papilas filiformes de la superficie de la lengua. Han sido implicados varios factores intrínsecos y extrínsecos como causales, entre ellos la pobre higiene dental, el tabaquismo, la ingesta de bebidas oscuras, el uso de antibióticos y algunas patologías malignas. Reportamos el caso de un paciente con carcinoma escamocelular avanzado de esófago medio conjunto con LNP, asociación no encontrada previamente en la literatura.

Abstract Black hairy tongue (BHT) is a benign disorder characterized by dark coloration and hypertrophy with hyperkeratosis in filiform papillae on the surface of the tongue. Several intrinsic and extrinsic factors, including poor dental hygiene, smoking, drinking dark beverages, indiscriminate use of antibiotics, and some malignant diseases, have been proposed as potential causes. This is the case of a patient with advanced squamous cell carcinoma of the mid esophagus in conjunction with BHT, a previously unknown association.

Linezolid induced black hairy tongue.

Black hairy tongue (BHT) also called as lingua villosa nigra, is a self limiting benign condition characterized by hypertrophy and elongation of filiform papillae of tongue with brown or black discoloration. Smoking, poor oral hygiene, xerostomia, using peroxide containing mouth washes, substance abuse and drugs (steroids, methyldopa, olanzapine, etc) are the predisposing factors. However its occurrence in relation to linezolid ingestion among south Indians has not been reported in PubMed database. Here we report a case, where significant association of linezolid intake with BHT was found in a 10-year-old boy, who was treated with tablet linezolid for post surgical infection of left side radial neck fracture. This case is reported for the rarity of occurrence with linezolid therapy. According to Naranjo adverse drug reaction (ADR) causality scale, the association of BHT due to linezolid in our case was probable.
