**Option D:** Option D also lacks context for evaluation.
**Clinical Pearl / High-Yield Fact**
Nasolabial cysts are important to distinguish from other facial swellings, such as **odontogenic cysts** or **salivary gland tumors**. Their diagnosis is often confirmed by **imaging studies** like CT or MRI scans.
