case_images: Histologic specimen of carcinoma ex pleomorphic adenoma of the parotid. Image shows the poorly differentiated malignant epithelial component in pleomorphic adenoma (A). Immunohistochemical staining demonstrated strong and diffuse positivity for a cocktail of cytokeratins (B).

case_images: In April of 2013, the patient underwent a new CT scan showing a low-density nodular lesion measuring 1.7 cm in the apical segment of the upper lobe of the left lung that had increased in volume and a hypovascular lesion measuring 4.8 cm in the superior-medial portion of the spleen, which had also increased in volume (Figure 3).
case_images: Histologic specimen of splenic metastasis. The spleen is involved by atypical epitheliomorphic cells, arranged in solid nests and cords with a round or oval nucleus and a large eosinophilic cytoplasm (A); immunohistochemical staining demonstrated positivity for cytokeratin 7 (B).
