....

..We discussed the appropriateness of limited resection for this type of lesion...

..Here, we present the case of a 37-year-old woman, with pathologically proven low-grade mucoepidermoid carcinoma, who underwent high-resolution computed tomography (CT) and F-18 FDG PET/CT before treatment...

..Punctate calcification in the pleural mass as a lesion distinct from the pleural plaque may indicate osseous or osteosarcomatous differentiation in malignant mesothelioma...

..The characteristic histology, immunoprofile, frequent ALK translocation, and total lack of EGFR or KRAS mutations, may suggest that Ad-SRCC forms a histologically/molecularly coherent subgroup of adenocarcinoma...
