Introduction: Genetic variability related to the host immune system has been proposed as one of the most influential factors in the development of diseases caused by HPV. Clinical case: We report the case of a 5-year-old child in whom chronic laryngeal papillomatosis, probably acquired vertically during labor, was detected. The diagnosis of laryngeal papillomatosis was confirmed with a biopsy after a first surgery to remove the papillomas. The Derkay classification system was used to assess the severity of papillomatosis. Biopsy genotyping was performed by demonstrating HPV-6. Later, HLAD-QA1*0505, -DQB1*0301, -DRB1*1101 alleles were homozygous for HLA allele typing. Conclusions: Further studies are needed to identify the most prevalent HLA alleles in the Latino population and their potential association with genetic susceptibility in Recurrent Respiratory Papillomatosis.

Introducción: El seudoquiste hemorrágico crónico puede presentarse después de la resecciónde grandes seudosacos eventrógenos. Su aparición es infrecuente.Caso clínico: Paciente que tras una cirugía con prótesis por un defecto en puerta de entradadespués de una colecistectomía laparoscópica consulta en el posoperatorio alejado por unatumoración sospechosa de recidiva herniaria. La ecografía y la tomografía axial computari-zada confirman el diagnóstico de seudoquiste hemorrágico crónico.Conclusiones: La disección de un gran saco eventrógeno rara vez presenta como complicaciónun seudoquiste hemorrágico crónico. La punción evacuadora es contemporizadora.
