[2025-10-01T21:32:09.031652] [PI reasoning] **Analyzing submandibular swelling**

I need to answer a question about tender swelling in the submandibular triangle. The likely diagnoses include submandibular gland infection, stones, lymphadenopathy, or Ludwig's angina. Tender swelling usually suggests lymphadenopathy, especially cervical lymph nodes. However, if it's Ludwig's angina, the swelling typically presents as brawny and bilateral rather than tender and fluctuant. Given the context of an ENT exam, I think it's most likely submandibular lymphadenitis or lymphadenopathy. Time to search quickly for more information!

[2025-10-01T21:32:17.019522] [PI reasoning] **Analyzing lymphadenopathy**

I’m seeing that the search results discuss general lymphadenopathy but might not be specific enough for our needs. It looks like we don’t necessarily need heavy literature since the focus is on anatomy and clinical issues. Tender swelling usually points to inflammation in lymph nodes, potentially representing acute lymphadenitis or an abscess. Among the options, A (lymphadenopathy) seems most relevant for tender swelling in the submandibular area. I'll look for citations to support this.
