Caviar tongue is a condition characterized by the purplish nodular swelling of veins found on the undersurface of the tongue. [1]It is normal for there to be veins visible underneath the tongue, partly because the mucous membrane is so thin and translucent in this region, but where these vessels become dilated and tortuous, they may appear round and black like caviar.

A venous lake (also known as phlebectasis [1]) is a generally solitary, soft, compressible, dark blue to violaceous, 0.2- to 1-cm papule commonly found on sun-exposed surfaces of the vermilion border of the lip, face and ears. [2] [3] [4] Lesions generally occur among the elderly. [5] [6]
Angiofibroma of soft tissue tumors consist of uniform, bland, spindle-shaped cells and a prominent vascular network consisting of small thin-walled branching blood vessels in a variably collagenous tissue background. Its tumor cells contain an AHRR-NCOA2 fusion gene in 60% to 80% of cases and a GTF2I-NCOA2 or GAB1-ABL1 fusion gene in rare cases ...
The lingual veins are multiple veins of the tongue with two distinct courses: one group drains into the lingual artery; another group drains either into the lingual artery, (common) facial vein, or internal jugular vein. [1]
Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. [1]: 808 The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. [2]
Surgical excision is available as a treatment for irritation fibromas. Though its reoccurrence is rare, it can happen if the cause of irritation continues. [4] Therefore, managing the cause is essential. [2] Irritation fibromas do not go away on their own if left untreated.
They are abnormal clusters of closely packed, thin-walled blood vessels that usually form caverns. The lesions contain slow-moving or clotted blood. Lesions in the brain and spinal cord are particularly fragile and likely to bleed. [8] Drawing of a microcystic lymphangioma on the left side of a boy's tongue
