Abstract

The association of systemic sarcoidosis with malignant neoplasms has been reported by several publications although there is controversy as to whether sarcoidosis predisposes patients to certain types of tumors or whether it is the tumors that cause a sarcoid reaction. The relationship between endobronchial carcinoid tumor and sarcoidosis is uncommon. We report the case of a 43-year-old male who was hospitalized due to hemoptysis. Thoracic CT revealed a pulmonary mass in the right upper lobe (RUL) as well as hypermetabolic lymphadenopathies seen with PET-CT. The endobronchial biopsies were compatible with carcinoid tumor. The patient underwent lobectomy of the RUL with mediastinal lymphadenectomy. Histology demonstrated type I endobronchial carcinoid tumor and sarcoid granulomas, both in the RUL surgical piece as well as in the mediastinal lymph nodes.

Resumen

La asociación de sarcoidosis sistémica con neoplasias malignas ha sido descrita en distintas publicaciones, aunque existe controversia sobre si la sarcoidosis predispone a ciertos tipos de tumores o si son estos los que provocan una reacción sarcoidal. La relación entre tumor carcinoide endobronquial y sarcoidosis es inusual. Describimos el caso de un varón de 43 años que ingresa por hemoptisis y en el que la tomografía computarizada (TC) torácica muestra una masa pulmonar en el lóbulo superior derecho (LSD) junto con adenopatías hipermetabólicas en la tomografía por emisión de positrones (PET)-TC. Las biopsias endobronquiales fueron compatibles con tumor carcinoide. El paciente fue intervenido, practicándosele lobectomía del LSD con linfadenectomía mediastínica reglada, cuya histología demostró tumor carcinoide tipo I endobronquial y granulomas sarcoideos, tanto en la pieza de LSD como en ganglios mediastínicos.
