Abstract
in English, Spanish

Lung tumorlets are rare neuroendocrine neoplasms of 0.5 cm or less in diameter that extend beyond the basement membrane. Although they are associated with bronchiectasis and fibrosis they tend to be asymptomatic and behave in a benign way, usually being diagnosed as incidental microscopic nests of neuroendocrine cells in lung tissue. We present a case of a pulmonary tumorlet finding after right upper lobectomy for lung cancer.

Los tumorlets pulmonares son neoplasias neuroendocrinas poco frecuentes, que se extienden más allá de la membrana basal y miden 0.5 cm o menos de diámetro. Aunque suelen asociarse a bronquiectasias y fibrosis pulmonar, suelen ser asintomáticas comportándose de una manera indolente, siendo usualmente diagnosticadas de forma incidental en el estudio microscópico de una pieza pulmonar. Presentamos el caso de un tumorlet pulmonar incidental luego de una lobectomía superior derecha por cáncer de pulmón.

Keywords: lung cancer; neuroendocrine tumor; tumorlet.
