Brenner tumors are uncommon surface-epithelial stromal cell tumors in which the epithelial cell (which defines these tumors) is a transitional cell. These are similar in appearance to bladder epithelia. The tumors may be very small to very large, and may be solid or cystic.referred chemotherapeutic agents include a platinum drug with a taxane. For surface epithelial-stromal tumors, the most common sites of metastasis are the pleural cavity (33%), the liver (26%), and the lungs (3%).
Pyogenic granuloma is one of the inflammatory hyperplasia seen in the oral cavity. The term is a misnomer because it is not related to infection and arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors.
Suppurative granulomas (granulomas with central abscess or microabscess formation) are characteristic findings in lymph nodes in cat scratch disease, lymphogranuloma venereum, and tularemia.
