Differential Diagnosis & Pitfalls
- Varix (varicosity; venous lake) – This appears blue to purple in color but affects older adults. Most varices develop over a period of months to years, and no rupture occurs.
- Hemangioma – This lesion usually develops early in life with little change in size. Most will blanch with diascopy.
- Benign salivary gland tumors – This presents as a constantly enlarging nodule instead of waxing and waning in size. Such tumors are often rubbery or firm on palpation.
- Low-grade mucoepidermoid carcinoma – This neoplasm presents as a constantly enlarging, usually firm, mass. While it could develop in the lower lip, the posterior hard palate, soft palate, buccal mucosa and retromolar area are more common locations.
