Abstract: Benign lymphoepithelial cysts are a widely recognized cause of parotid gland swelling in patients infected with the human immunodeficiency virus (HIV). These cysts are pathognomonic for HIV. The cysts frequently grow to be exceptionally large, causing physical deformity and gross asymmetry of facial contour.
Is swollen parotid glands symptom of HIV?
Parotid gland enlargement is typically an early manifestation in the HIV-positive patient and should alert healthcare professionals to the likelihood of HIV infection. FNAC of the parotid gland is required to confirm the diagnosis and instituting HAART forms an important part of the management.
What causes Lymphoepithelial cyst?
Benign lymphoepithelial cysts are a widely recognized cause of parotid gland swelling in patients infected with the human immunodeficiency virus (HIV). These cysts are pathognomonic for HIV. The cysts frequently grow to be exceptionally large, causing physical deformity and gross asymmetry of facial contour.
What is benign Lymphoepithelial cyst?
Benign lymphoepithelial cysts (BLECs) are benign, slow-growing, uninoculated or multiloculated lesions that are usually associated with the salivary glands in the head and neck regions. BLECs are more commonly observed in up to 60% – 80% of female patients [1].
What is Lymphoepithelial cyst?
Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland) and the oral cavity (usually the floor of the mouth).
Why do cysts grow?
Cysts are most commonly caused by blockage in a duct, which can be due to trauma, infection, or even an inherited tendency. The type of cyst depends on where it forms – some cysts can be internal (such as in a breast, the ovaries, or the kidneys) while others are external and form in visible locations on the body.
What viral infection causes swollen salivary glands?
Viral infections such as mumps, flu, and others can cause swelling of the salivary glands. Swelling happens in parotid glands on both sides of the face, giving the appearance of “chipmunk cheeks.” Salivary gland swelling is commonly associated with mumps, happening in about 30% to 40% of mumps infections.
What are Lymphoepithelial cysts?
What is Lymphoepithelial lesion?
In pathology, lymphoepithelial lesion refers to a discrete abnormality that consists of lymphoid cells and epithelium, which may or may not be benign.
What is benign cyst?
A cyst is a sac that may be filled with air, fluid or other material. A cyst can form in any part of the body, including bones, organs and soft tissues. Most cysts are noncancerous (benign), but sometimes cancer can cause a cyst. Tumor.
What are AIDS-related parotid cysts?
Benign lymphoepithelial lesions (BLL or BLEL), also misleadingly known as AIDS-related parotid cysts (ARPC), are mixed solid and cystic lesions that enlarge the parotid glands, and are usually associated with cervical lymph node enlargement, and nasopharyngeal lymphofollicular hyperplasia. Article: Terminology.
Can HIV cause swelling of the parotid glands and BLEC?
We report a case of a 65-year-old Japanese man with swelling of the parotid glands and HIV-associated BLEC confirmed via HIV-1 p24 immunohistochemical staining.
How is HIV-associated benign parotid lymphocytic lymphoma (BLEC) diagnosed?
The diagnosis of HIV-associated BLEC is predominantly made through blood and imaging tests in patients with asymptomatic parotid gland swelling, and to the best of our knowledge only a few reports have shown direct diagnosis of HIV-associated BLEC through immunohistochemical detection of the HIV-1 p24 antigen.
How common are benign lymphoepithelial lesions in HIV infection?
Despite their aforementioned alternative name, benign lymphoepithelial lesions are seen usually in HIV positive patients without AIDS, and are not an AIDS defining illness. It is relatively common in the HIV population, with 5% of patients eventually developing benign lymphoepithelial lesions.
