The presence of small red dots on the lips and tongue is highly indicative of Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome. This condition is characterized by the development of vascular malformations that often present as small, cherry-red spots or telangiectasias in various mucosal surfaces, including the lips and tongue. These lesions are caused by abnormal blood vessel formation that can lead to bleeding, making the identification of red dots significant in the diagnosis of HHT.

Petechiae, while also presenting as small red spots, typically result from the rupture of small blood vessels and can occur in many contexts, including thrombocytopenia or vasculitis. However, they are not limited to areas like the lips and tongue or associated with genetic disorders.

A hematoma is a localized collection of blood outside of blood vessels, usually resulting from trauma, and would not present as small dots but rather as more substantial bruising or swelling.

Hemangioma is a benign tumor composed of blood vessels, primarily presenting in infants and not typically as small dots on the lips and tongue, but rather as larger, raised lesions.

Given the symptoms and the presentation, Hereditary Hemorrh
