From: Benign metastasizing leiomyoma presenting as multiple cystic pulmonary nodules: a case report
Representative H&E-stained sections of the pulmonary nodule (a) and the uterine mass (b). a The pulmonary nodule showed complex branching glandular structures lined by a single layer of simple cuboidal to columnar epithelium surrounded by abundant spindle cells. There was no atypia or mitotic activity in either the epithelial or the spindle cell components (H&E staining, × 100). b The uterine mass resected 14 years prior consisted of myometrium-derived smooth muscle cells and extracellular matrix
