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. When found on the floor of the mouth, the mucocele is referred to as a ranula. They are rarely found on the upper lip.
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.
It can also be found on the lips, tongue, and inner cheek. Poor oral hygiene or trauma are usually precipitating factors. [citation needed] One study has suggested a correlation between pyogenic granulomas and Bartonella seropositivity. [9] However, this association has been questioned by others. [10]
They are painless papules (small bumps), about 1–3 mm in greatest dimension. The most common site is along the line between the vermilion border and the oral mucosa of the upper lip, or on the buccal mucosa (inside the cheeks) in the commissural region, [10] often bilaterally. They may also occur on the mandibular retromolar pad and tonsillar ...
Rib fractures may tear the parietal pleura, the membrane lining the inside of chest wall, allowing air to escape into the subcutaneous tissues. [ 13 ] Subcutaneous emphysema is frequently found in pneumothorax (air outside of the lung in the chest cavity) [ 14 ] [ 15 ] and may also result from pneumomediastinum (air in the mediastinum) or ...
Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. [2] The differential diagnosis is with leukoplakia , oral candidiasis , oral lichen planus , white sponge nevus , morsicatio buccarum , [ 3 ] hereditary benign intraepithelial dyskeratosis and dyskeratosis congenita.
White sponge nevus (WSN) is an extremely rare autosomal dominant [4] condition of the oral mucosa (the mucous membrane lining of the mouth). It is caused by one or more mutations in genes coding for keratin , which causes a defect in the normal process of keratinization of the mucosa.
Epidermoid cysts are usually diagnosed when a person notices a bump on their skin and seeks medical attention. The definitive diagnosis is made after excision by a pathologist based on microscopic appearance of a cystic lesion lined by cornified epithelium containing lamellated keratin without calcifications.
