RIVERA-VEGAS, María Jesús; RUIZ-ALONSO, Elena; PENA-PEREZ, Ángel  y  RODRIGUEZ-VEGA, Andrea. Iatrogenic epidermal cyst in the parotid region: a rare complication of otologic surgery. Cir. plást. iberolatinoam. [online]. 2018, vol.44, n.4, pp.437-441.  Epub 08-Feb-2021. ISSN 1989-2055.  https://dx.doi.org/10.4321/s0376-78922018000400016.

Epidermal cysts are common skin lesions, however the presence of epidermal cysts within the salivary glands is rare as well as reflect the few cases reported in the literature. Its origin is the iatrogenic implantation of epithelial tissue in the gland and it should be considered as a differential diagnosis when a patient presents a tumor in the parotid region with previous history of otologic surgery.

We report a case of a woman operated of a parotid lesion with histopathological diagnosis of intraparotid epidermoid cyst. In her personal clinical history, she has been operated for ipsilateral tympanoplasty in childhood, being considered this the cause of the lesion.

Our aim is to emphasize the rarity of the presentation of the pathology, the consideration of epidermal cysts as a complication in otologic surgery, although uncommon, and its importance as a differential diagnosis in tumor lesions of the parotid gland.

Palabras clave : Epidermal cyst; Salivary gland; Parotid gland; Tympanoplasty.
