Abstract

Pure ground-glass opacity nodules (p-GGN) on high-resolution computed tomography (HRCT) generally have been considering typically associated with adenocarcinoma with less invasive nature. We herein reported a patient presenting focal p-GGN on middle lobe of the right lung who underwent surgical resection with its pathological diagnosis turned out to be typical carcinoid tumor.

Highlights

Pure ground-glass opacity nodules (p-GGN) are frequently identified in the lung parenchyma on high-resolution computed tomography (HRCT)
We report a case of a resected typical carcinoid tumor that presented as a persistent p-GGN on HRCT
The patient underwent right mastectomy and sentinel lymph node dissection, and the pathological diagnosis was papillotubular carcinoma without lymph node metastasis. She was referred to our department in December 2009, and underwent another HRCT examination in March

Summary

Introduction

Pure ground-glass opacity nodules (p-GGN) are frequently identified in the lung parenchyma on high-resolution computed tomography (HRCT). The pathology of p-GGN on HRCT was reported to be atypical adenomatous hyperplasia (AAH), adenocarcinoma, focal organizing pneumonia/fibrosis [1] and so on. We report a case of a resected typical carcinoid tumor that presented as a persistent p-GGN on HRCT.
