Tracheal Mucoepidermoid Carcinoma Mimicking Deteriorated Bronchial Asthma during Pregnancy

Figure 3

Macroscopic and microscopic findings of the resected bronchial tumor. The excised specimen occupying the bronchi was soft (a). Pathologically, a nodular polypoid tumor is arising from the bronchial wall, based mainly at the membranous portion consisting of a mixture of epithelial and fibromyxoid stromal elements. In addition, neither a high mitotic activity nor extrabronchial invasive growth is noted, indicating the diagnosis of a low-grade mucoepidermoid carcinoma (b, c).
