Pediatric Salivary Gland Neoplasms


• hemangiomas and pleormorphic adenomas are the most common benign parotid tumors of childhood

• excluding hemangiomas, salivary gland infections, and lymphangiomas, >50% of parotid solid masses are malignant

• well-differentiated mucoepidermoid tumors are the most common salivary gland malignancy in children


• benign tumor of endothelial origin

• usually discovered at birth

• more common in Caucasian females

• 50% association with cutaneous hemangiomas

Capillary Hemangiomas

• constant shape, enlarges in proportion to growth of child

• may involve facial nerve

• SSx: lobulated, dark red and bluish mass overlying skin

• Histology: unencapsulated, capillary sized vessels, may invade facial nerve

• Rx: avoid surgery in childhood; tattooing, cryotherapy, laser obliteration

Cavernous Hemangiomas

• may enlarge rapidly

• 60% spontaneously resolve by 4—6 years old

• less chance of regression than capillary hemangiomas

• Rx: corticosteroid therapy, may consider surgery if lesion can be completely removed, failure to involute, rapid growth threatens perioral, periorbital, or nasal tip regions
