Objetivo: describir los casos de parasitismo imaginario observados en el Laboratorio de Entomología Médica, Facultad de Microbiología, Universidad de Costa Rica durante 2001-2011. Métodos: se describen 9 casos cuyas características coincidieron con cuadros de parasitismo imaginario, y se analiza la “evidencia diagnóstica” aportada por algunos de los pacientes como causa de su enfermedad. Resultados: los pacientes refirieron problemas crónicos a nivel de piel y cuero cabelludo con síntomas y signos atribuidos, según su propio criterio, a diferentes tipos de artrópodos. Dichos pacientes ya habían recurrido a consultas previas, sin éxito en el diagnóstico esperado. Las muestras aportadas permitieron identificar artrópodos como psycodinos (Diptera: Psychodinae), psócidos (Psocoptera), moscas (Diptera: Cyclorrhapha), homópteros (Homoptera), hormigas (Hymenoptera: Formicidae), (isópteros) y arañas (Arácnida: Aranea) los cuales son irrelevantes en cuanto a su importancia médica. También se detectaron granos, fibras vegetales, coágulos de fibrina y trozos de queratina dérmica. Discusión: se hace énfasis al personal clínico y de laboratorio para la ejecución de un correcto diagnóstico e identificación de las posibles causas, antes de proceder a administrar un tratamiento medicamentoso antiparasitario.
Aim: To describe the cases of delusional parasitosis observed in the Laboratory of Medical Entomology, School of Microbiology, University of Costa Rica during 2001-2011. Methods: Nine cases compatible with delusional parasitosis are described. The “diagnostic evidence” provided by patients as cause of their illness is also analyzed. Results: These patients referred chronic problems on skin and scalp with signs and symptoms attributed, in their opinion, to different types of arthropods. These patients had already been evaluated by a physician and had been unsuccessful with the expected diagnosis. The samples provided included several types of arthropods, such as, psychodinae (Diptera: Psychodinae), booklice (Psocoptera), true bugs (Homoptera), flies (Diptera: Cyclorrhapha), ants (Hymenoptera: Formicidae), Isoptera and house spiders (Arachnida: Aranea), that are irrelevant in terms of medical importance. Other materials such as grains, vegetable fibers, fibrin clots, and pieces of skin were also detected. Discussion: We emphasize the importance of a correct diagnosis and identification of possible causes of this syndrome before administering treatment with anti-parasitic drugs.
