Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose. The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth.
Liposarcoma is found in 1% of lipomas and is more likely to occur in lesions of the lower extremities, shoulders, and retroperitoneal areas. Other risk factors for liposarcoma include large size (>5 cm), associated with calcification , rapid growth, and/or invasion into nearby structures or through fascia into muscle tissue .
The tumor may be in the form of a hard plaque or a papule, often with an opalescent quality, with tiny blood vessels; The tumor can lie below the level of the surrounding skin, and eventually ulcerates and invades the underlying tissue; The tumor commonly presents on sun-exposed areas (e.g. back of the hand, scalp, lip, and superior surface of ...
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]
They are caused by prolonged irritation in the mouth, such as cheek or lip biting, rubbing from teeth, and dental prostheses. The fibromas are firm, smooth, and fibrous with a color usually identical to the oral mucosa but can be paler. If wounded, it may be darker. They are usually solitary and do not develop into oral cancer.

Ulceration on the left lower lip caused by cancer. The signs and symptoms of oral cancer depend on the location of the tumor but are generally thin, irregular, red and/or white patches in the mouth. The classic warning sign is a persistent rough patch with ulceration, and a raised border that is minimally painful.
Periapical cysts begin as asymptomatic and progress slowly. Subsequent infection of the cyst causes swelling and pain. Initially, the cyst swells to a round hard protrusion, but later on the body resorbs some of the cyst wall, leaving a softer accumulation of fluid underneath the mucous membrane. [citation needed]
