Question 41 (part 2) · LDEK · Salivary gland diseases
Indicate true statements regarding the cysts of salivary glands:
1) the vast majority (more than 80%) of mucous retention cyst involves lower lip;
2) discovery of a cyst of large salivary glands should always be a signal for starting the diagnostic process, that may eliminate cancerous background, because in large salivary glands, cancers most often establish cystic structures;
3) lymphoepithelial cyst develops significantly more often in patients with HIV;
4) ductal salivary cyst belongs to the group of true cysts;
5) ranula develops due to Rivini duct injury or its congenital anomaly.
