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.
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]
Epulis (literally, 'on the gingiva') is a general term for any gingival or alveolar tumor (i.e. lump on the gum). [1] This term describes only the location of a lump and has no implication on the histologic appearance of a lesion. [3]
Epulis (Greek: ἐπουλίς; plural epulides) is any tumor-like enlargement (i.e. lump) situated on the gingival or alveolar mucosa. [1] [2] The word literally means "(growth) on the gingiva", [3] [4] and describes only the location of the mass and has no further implications on the nature of the lesion. [5]
Poor surgical technique, or previous infection leading to scarring and tethering of the cyst to the surrounding tissue, may lead to rupture during excision and removal. A completely removed cyst will not recur, though if the patient has a predisposition to cyst formation, further cysts may develop in the same general area.
Ranula in a female. A ranula usually presents as a translucent, blue, dome-shaped, fluctuant swelling in the tissues of the floor of the mouth. If the lesion is deeper, then there is a greater thickness of tissue separating from the oral cavity and the blue translucent appearance may not be a feature.
Palpable hard lump, if the stone is located near the end of the duct. [1] [3] If the stone is near the submandibular duct orifice, the lump may be felt under the tongue. Lack of saliva coming from the duct (total obstruction). [3] Erythema (redness) of the floor of the mouth (infection). [3] Pus discharging from the duct (infection). [3]
The tumor commonly presents on sun-exposed areas (e.g. back of the hand, scalp, lip, and superior surface of pinna) On the lip, the tumor forms a small ulcer, which fails to heal and bleeds intermittently; Evidence of chronic skin photodamage, as in multiple actinic keratoses (solar keratoses) The tumor grows relatively slowly
