<\/span><\/h2>\nThe choristoma is a rare benign<\/span> tumor<\/span> It consists of microscopically normal tissue derived from layers of germ cells foreign to that site in the body. Choristomas are classified according to their tissue type. Sometimes they arise within the skin or oral cavity, and can also occur in the internal organs.<\/p>\n\n- Dermoid cyst<\/span> is made up of the components of epidermis<\/span> and dermis<\/span>, including hair<\/span>.<\/li>\n
- The choristoma of the oral cavity may contain epidermal<\/span> components (skin, hair follicles<\/span>, sebaceous<\/span> glands), bone (bony), cartilage, lingual, gastric, respiratory, salivary or glial tissue.<\/li>\n
- The phaquomatous choristoma of the eyelid or orbit contains embryological precursor cells of the lens (lenticular anlage).<\/li>\n
- The epibulbar or corneal choristoma arises in the limbus of the eye and may include dermoid, lipodermoid, or other tissues.<\/li>\n
- The choristoma within the ear canal usually contains cartilage.<\/li>\n
- Choristoma of the salivary gland has been reported in the previous<\/span> chest wall and chest.<\/li>\n<\/ul>\n
<\/span>Who gets the choristoma?<\/span><\/h2>\nThe choristoma can be diagnosed at any age from birth to old age. All epidermal choristomas have occurred in males. Most cases of lingual bone choristoma have been reported in women in the third and fourth decades. Phakatous choristoma and salivary gland choristoma tend to arise in newborns.<\/p>\n

<\/span>What causes the choristoma?<\/span><\/h2>\nThe choristoma is a developmental abnormality. For example, a dermoid cyst arises from epithelium<\/span> trapped along embryonic fusion lines. The reason why they occur late in life is unknown in some cases. One theory is that it may be due to chronic<\/span> irritation.<\/p>\n<\/span>What are the clinical features of the choristoma?<\/span><\/h2>\nEpidermal choristoma on the dorsum of the tongue most often occurs brown to black pigmented<\/span> taint<\/span> variable in size (3\u201311 mm). the differential diagnosis<\/span> pigmented macular<\/span> the choristoma on the tongue includes congenital<\/span> melanotic macula and melanocytic<\/span> nevus<\/span>.<\/p>\nThe bone choristoma presents as pedunculated<\/span>, painless hard lump on the back of the tongue, later<\/span> to the foramen caecum. Oral choristoma can also occur in the gum or mouth mucous membrane<\/span>.<\/p>\nThe phakomatous choristoma has a similar appearance, but it arises around the orbit or the eyelid region. The clinical concern may be rhabdomyosarcoma.<\/p>\n
A choristoma in the ear canal presents as a mass that causes hearing loss and can predispose<\/span> to infection<\/span>.<\/p>\n<\/span>How is choristoma diagnosed?<\/span><\/h2>\nThe choristoma is diagnosed in biopsy<\/span> or excision<\/span>, to find histological<\/span> features that confirm microscopically normal cells in an abnormal location.<\/p>\n\n

<\/span>What is the treatment of choristoma?<\/span><\/h2>\nThe choristoma is usually removed.<\/p>\n
<\/span>What is the result for patients with choristoma?<\/span><\/h2>\nLesions are benign with little risk of evil one<\/span> transformation. Reappearance<\/span> Post-spin rates are extremely low.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"\u00bfQu\u00e9 es el coristoma?
