Metastasizing pleomorphic adenoma of the parotid gland. A case report and descriptive retrospective study of english literature

The pleomorphic adenoma (PA) -ICD-O-8940/0- is the most common benign epithelial tumor of salivary glands, of pleomorphic histological appearance with ductal cells and myoepitheliocytes and hyalinized, chondroids and myxoids stromal areas. The metastasizing pleomorphic adenoma (MPA) it is an extreme...

Salivary Gland Neoplasms Parotid Gland Adenoma Pleomorphic Neoplasm Metastasis Lung Tumores de las Glándulas Salivales Glándula Parótida Adenoma Pleomórfico Metástasis Pulmón The pleomorphic adenoma (PA) -ICD-O-8940/0- is the most common benign epithelial tumor of salivary glands, of pleomorphic histological appearance with ductal cells and myoepitheliocytes and hyalinized, chondroids and myxoids stromal areas. The metastasizing pleomorphic adenoma (MPA) it is an extremely rare tumor with an aggressive behavior since it produces metastasis but retains its benign phenotype. In the fourth edition (year 2017) of the Classification of head and neck tumors of the WHO occupies a subcategory of PA within the session of benign tumors. In this communication, we present a rare case of MPA of the parotid gland with multiple lung metastases. The histopathological study (H/E) of the surgical piece of total parotidectomy and lymphoid nodes was performed and a PA was diagnosed. In a routine control, a chest radiograph was requested, where multiple nodular images were observed in both lungs consistent with metastasis. A lung biopsy was performed, identifying tumor formations similar to the parotid tumor.The majority of published cases occur after surgery of a primary or recurrent tumor and several authors suggest that surgical manipulation can cause tumor cell separation, hematogenous spread and subsequent implantation in distant sites. El adenoma pleomórfico (AP) -ICD-O- 8940/0- es el tumor epitelial benigno más común de glándulas salivales, de apariencia histológica pleomórfica con células ductales y mioepiteliocitos y áreas estromales hialinizadas, condroides y mixoides. El adenoma pleomórfico metastásico (APM) es un tumor extremadamente raro con un comportamiento agresivo ya que produce metástasis pero conserva su fenotipo benigno. En la cuarta edición (año 2017) de la “Clasificación de tumores de cabeza y cuello” de la Organización Mundial de la Salud (OMS) ocupa una subcategoría de AP dentro de la sesión de tumores benignos. En esta comunicación presentamos un raro caso de APM de glándula parótida con múltiples metástasis en pulmón. Se realizó el estudio histopatológico (H/E) de la pieza quirúrgica de parotidectomía total y nodos linfoides y se diagnosticó adenoma pleomórfico. En un control de rutina se le solicitó radiografía de tórax donde se observaron imágenes nodulares múltiples en ambos pulmones consistentes con metástasis. Se hizo una punción biopsia de pulmón identificándose formaciones tumorales similares al tumor parotídeo. La mayoría de los casos publicados ocurren después de la cirugía de un tumor primario o recurrente y diversos autores sugieren que la manipulación quirúrgica puede causar separación de células tumorales, propagación hematógena y posterior implantación en sitios distantes.
