case_images: A CT scan was performed which shows decreased tracheal lumen and thickening of the thyroid and cricoid cartilages (Figure 1).
case_images: A cartilage is identified with destruction by infiltration of a glandular neoplasia, with formation of small nodules with microlens as well as individually. In other fields, it presents a cribriform pattern, where the presence of large and multiple nucleoli stands out. The neoplastic cells are of medium size, polygonal, with broad vacuolated cytoplasm, with large, hyperchromatic, and pleomorphic nuclei, and with a prominent nucleus and eosinophil.

case_images: Metastatic carcinoma with the ductal cribriform pattern was corroborated (Figure 2).

case_images: For the previous reason, palliative radiotherapy was decided as treatment to the larynx, during which the patient presented a nodule in the oral cavity in the upper right gingival area with a hard palate extension (Figure 3).
case_images: A neoplasm with an infiltration pattern is identified in small- and medium-sized nodules, surrounded by desmoplastic stroma. In some areas, minimal formation of tubular structures with low eosinophilic luminal secretion is identified. The cells that make up the neoplasia are large in size, with abundant cytoplasm, with a clear "foamy" aspect, with peripheral nuclei, and with some central, hyperchromatic, large, and regular borders.
