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.

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.

Reversible black tongue: A little known side effect of imipenem/cilastatin and evidence for novel mode of action.

WHAT IS KNOWN AND OBJECTIVE: Black tongue syndrome (BT) is a rare and self-limiting disorder which can result from physiological and metabolic condition and ingestion of toxic substances. Medications are the most common cause of BT. CASE SUMMARY: A 39-year-old male patient presented with BT after the initiation of imipenem/cilastatin. Within one week of cessation of these drugs, the patient's tongue returned to a normal colour. WHAT IS NEW AND CONCLUSION: This is the first case of BT induced by imipenem/cilastatin. Withdrawal of the combination is likely to reverse the condition.

Ranitidine-induced black tongue: A case report.

Black tongue is a rare, benign, self-limiting disorder caused by certain conditions and some medications. We report the first case of a child diagnosed with black tongue associated with ranitidine use. We report our case to emphasize the rare side effect of this frequently used drug. Health care professionals should be aware of the likelihood of ranitidine-induced black tongue in clinical practice.
