(B) Pathological appearance of benign metastasizing leiomyoma at high magnification (haematoxylin and eosin staining). (C) Positive staining for desmin in smooth muscle cells of the lung nodule. (D) Immunohistochemical staining for keratin (CK AE1/AE3) is positive in pulmonary alveoli. (E) Immunohistochemical staining for ER is positive in muscle cells of the lung nodule.

-Morphology: The morphology associated with leiomyoma shows monotonous spindle cells with indistinct borders arranged in intersecting fascicles.

-Histology: The histology associated with leiomyoma shows bundles or fascicles of spindled cells with eosinophilic and possibly fibrillar cytoplasm
