Abstract

To the Editor: We read, with interest, the article “Resection of a Solitary Pulmonary Metastasis from Prostatic Adeno carcinoma Misdiagnosed as a Bron chocele: Usefulness of 18F-Choline and 18F-FDG PET/CT” by Calais et al. 1 . We agree entirely that there is a valuable learning point from this case and would like to share a recent case from our institution to reinforce this lesson. An 84-year-old female patient with a previous colorectal mucinous adenocarcinoma, treated with surgical resection, presented with a cough. Subsequent chest radiograph (CXR) and computer tomography (CT) scan confirmed the presence of a lobulated and elongated lesion (finger in glove sign) in the right middle lobe consistent with a bronchocele ( Fig. 1 ). The patient went on to have an 18-F-fluorodeoxyglucose (FDG) positron emission computed tomography (PET)-CT scan, which demonstrated no FDG uptake within the lesion, again consistent with a bronchocele ( Fig. 2 ). Bronchoscopy demonstrated an intraluminal obstruction of the right middle lobe by solid, green-yellow tissue. The tissue could not be cleared with suction or by application of saline. Endobronchial biopsies yielded large clumps of tissue and, to our surprise, histopathological analysis revealed mucin-secreting tumor cells. The tumor demonstrated strong immunopositivity
