A malignant epithelial tumor of glandular tissue, especially the salivary glands, characterized by acini with mucus-producing cells and by the presence of malignant squamous elements. Most mucoepidermoid tumors are low-grade lesions readily cured by adequate excision. They may appear in any age group. They grow slowly. If high-grade, they behave aggressively, widely infiltrating the salivary gland and producing lymph node and distant metastases. (Dorland, 27th ed; from DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575)
A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)
Tumors or cancer of the SALIVARY GLANDS.
Accessory salivary glands located in the lip, cheek, tongue, floor of mouth, palate and intramaxillary.
Tumors or cancer of the PAROTID GLAND.
A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.
Tracheal neoplasms are abnormal growths or tumors that develop within the trachea, which can be benign or malignant, and have the potential to obstruct the airway and impair respiratory function.
A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth. (Dorland, 27th ed)
Carcinoma characterized by bands or cylinders of hyalinized or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumors occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (Dorland, 27th ed)
A malignant tumor arising from secreting cells of a racemose gland, particularly the salivary glands. Racemose (Latin racemosus, full of clusters) refers, as does acinar (Latin acinus, grape), to small saclike dilatations in various glands. Acinar cell carcinomas are usually well differentiated and account for about 13% of the cancers arising in the parotid gland. Lymph node metastasis occurs in about 16% of cases. Local recurrences and distant metastases many years after treatment are common. This tumor appears in all age groups and is most common in women.

A mucoepidermoid tumor is a type of salivary gland neoplasm (abnormal growth) that can occur in the major or minor salivary glands. These tumors are characterized by the presence of mucus-secreting cells, epidermoid cells (which resemble skin cells), and intermediate cells.

Mucoepidermoid tumors are classified into three grades based on their histological features: low grade, intermediate grade, and high grade. Low-grade mucoepidermoid tumors tend to grow slowly and have a better prognosis compared to higher-grade tumors, which are more aggressive and have a higher risk of recurrence and metastasis (spread to other parts of the body).

Treatment for mucoepidermoid tumors typically involves surgical excision. The extent of surgery depends on the location, size, and grade of the tumor. Radiation therapy may also be recommended in some cases, particularly for high-grade tumors or when there is a high risk of residual tumor after surgery.

Mucoepidermoid carcinoma is a type of cancer that develops in the salivary glands or, less commonly, in other areas such as the lungs or skin. It is called "mucoepidermoid" because it contains two types of cells: mucus-secreting cells and squamous (or epidermoid) cells.

Mucoepidermoid carcinomas can vary in their behavior, ranging from low-grade tumors that grow slowly and rarely spread to other parts of the body, to high-grade tumors that are aggressive and can metastasize. The treatment and prognosis for mucoepidermoid carcinoma depend on several factors, including the grade and stage of the tumor, as well as the patient's overall health.

It is important to note that while I strive to provide accurate and up-to-date information, this definition may not capture all the nuances of this medical condition. Therefore, it is always best to consult with a healthcare professional for medical advice.

Salivary gland neoplasms refer to abnormal growths or tumors that develop in the salivary glands. These glands are responsible for producing saliva, which helps in digestion, lubrication of food and maintaining oral health. Salivary gland neoplasms can be benign (non-cancerous) or malignant (cancerous).

Benign neoplasms are slow-growing and typically do not spread to other parts of the body. They may cause symptoms such as swelling, painless lumps, or difficulty swallowing if they grow large enough to put pressure on surrounding tissues.

Malignant neoplasms, on the other hand, can be aggressive and have the potential to invade nearby structures and metastasize (spread) to distant organs. Symptoms of malignant salivary gland neoplasms may include rapid growth, pain, numbness, or paralysis of facial nerves.

Salivary gland neoplasms can occur in any of the major salivary glands (parotid, submandibular, and sublingual glands) or in the minor salivary glands located throughout the mouth and throat. The exact cause of these neoplasms is not fully understood, but risk factors may include exposure to radiation, certain viral infections, and genetic predisposition.

Minor salivary glands are numerous small exocrine glands that produce saliva and are distributed throughout the oral cavity, nasal cavity, pharynx, larynx, and paranasal sinuses. They are classified as "minor" due to their smaller size compared to the three pairs of major salivary glands (parotid, submandibular, and sublingual). The minor salivary glands are primarily mucous glands, although some contain serous cells. They are responsible for producing approximately 5-10% of the total saliva in the mouth. These glands help moisten the oral cavity, protect the mucosal lining, and facilitate speaking, chewing, and swallowing.

Parotid neoplasms refer to abnormal growths or tumors in the parotid gland, which is the largest of the salivary glands and is located in front of the ear and extends down the neck. These neoplasms can be benign (non-cancerous) or malignant (cancerous).

Benign parotid neoplasms are typically slow-growing, painless masses that may cause facial asymmetry or difficulty in chewing or swallowing if they become large enough to compress surrounding structures. The most common type of benign parotid tumor is a pleomorphic adenoma.

Malignant parotid neoplasms, on the other hand, are more aggressive and can invade nearby tissues and spread to other parts of the body. They may present as rapidly growing masses that are firm or fixed to surrounding structures. Common types of malignant parotid tumors include mucoepidermoid carcinoma, adenoid cystic carcinoma, and squamous cell carcinoma.

The diagnosis of parotid neoplasms typically involves a thorough clinical evaluation, imaging studies such as CT or MRI scans, and fine-needle aspiration biopsy (FNAB) to determine the nature of the tumor. Treatment options depend on the type, size, and location of the neoplasm but may include surgical excision, radiation therapy, and chemotherapy.

Adenolymphoma is a rare, benign tumor that arises from the lymphoid tissue found in glandular structures, such as the salivary glands. It is also known as Warthin's tumor or cystic papillary adenolymphoma.

The tumor is composed of multiple cyst-like spaces lined by columnar epithelial cells and surrounded by lymphoid tissue, which may contain lymphocytes, plasma cells, and occasionally, germinal centers. The etiology of adenolymphoma is unclear, but it has been associated with smoking and genetic factors.

Adenolymphomas are typically slow-growing and painless, although they can cause discomfort or facial asymmetry if they become large enough. They are usually diagnosed through imaging studies such as ultrasound, CT scan, or MRI, followed by a biopsy to confirm the diagnosis.

Treatment of adenolymphoma typically involves surgical excision, which is usually curative. Recurrence after surgery is rare, but long-term follow-up is recommended due to the potential for malignant transformation into squamous cell carcinoma or other malignancies.

Tracheal neoplasms refer to abnormal growths or tumors in the trachea, which is the windpipe that carries air from the nose and throat to the lungs. These growths can be benign (non-cancerous) or malignant (cancerous). Malignant tracheal neoplasms are relatively rare and can be primary (originating in the trachea) or secondary (spreading from another part of the body, such as lung cancer). Primary tracheal cancers can be squamous cell carcinoma, adenoid cystic carcinoma, mucoepidermoid carcinoma, or sarcomas. Symptoms may include cough, difficulty breathing, wheezing, or chest pain. Treatment options depend on the type, size, and location of the neoplasm and can include surgery, radiation therapy, chemotherapy, or a combination of these approaches.

A pleomorphic adenoma is a type of benign (non-cancerous) tumor that typically develops in the salivary glands, although they can also occur in other areas such as the nasopharynx and skin. "Pleomorphic" refers to the diverse appearance of the cells within the tumor, which can vary in size, shape, and arrangement.

Pleomorphic adenomas are composed of a mixture of epithelial and mesenchymal cells, which can form glandular structures, squamous (scale-like) cells, and areas that resemble cartilage or bone. These tumors tend to grow slowly and usually do not spread to other parts of the body.

While pleomorphic adenomas are generally not dangerous, they can cause problems if they become large enough to press on surrounding tissues or structures. In some cases, these tumors may also undergo malignant transformation, leading to a cancerous growth known as carcinoma ex pleomorphic adenoma. Surgical removal is the standard treatment for pleomorphic adenomas, and the prognosis is generally good with proper management.

Adenoid cystic carcinoma (AdCC) is a rare type of cancer that can occur in various glands and tissues of the body, most commonly in the salivary glands. AdCC is characterized by its slow growth and tendency to spread along nerves. It typically forms solid, cystic, or mixed tumors with distinct histological features, including epithelial cells arranged in tubular, cribriform, or solid patterns.

The term "carcinoma" refers to a malignant tumor originating from the epithelial cells lining various organs and glands. In this case, adenoid cystic carcinoma is a specific type of carcinoma that arises in the salivary glands or other glandular tissues.

The primary treatment options for AdCC include surgical resection, radiation therapy, and sometimes chemotherapy. Despite its slow growth, adenoid cystic carcinoma has a propensity to recur locally and metastasize to distant sites such as the lungs, bones, and liver. Long-term follow-up is essential due to the risk of late recurrences.

Carcinoma, acinar cell is a type of pancreatic cancer that originates in the acinar cells of the pancreas. The acinar cells are responsible for producing digestive enzymes. This type of cancer is relatively rare and accounts for less than 5% of all pancreatic cancers. It typically presents with symptoms such as abdominal pain, weight loss, and jaundice. Treatment options may include surgery, chemotherapy, and radiation therapy.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Mucus is a viscous, slippery secretion produced by the mucous membranes that line various body cavities such as the respiratory and gastrointestinal tracts. It serves to lubricate and protect these surfaces from damage, infection, and foreign particles. Mucus contains water, proteins, salts, and other substances, including antibodies, enzymes, and glycoproteins called mucins that give it its characteristic gel-like consistency.

In the respiratory system, mucus traps inhaled particles such as dust, allergens, and pathogens, preventing them from reaching the lungs. The cilia, tiny hair-like structures lining the airways, move the mucus upward toward the throat, where it can be swallowed or expelled through coughing or sneezing. In the gastrointestinal tract, mucus helps protect the lining of the stomach and intestines from digestive enzymes and other harmful substances.

Excessive production of mucus can occur in various medical conditions such as allergies, respiratory infections, chronic lung diseases, and gastrointestinal disorders, leading to symptoms such as coughing, wheezing, nasal congestion, and diarrhea.
