Adenoid Cystic Carcinoma with Transformation to High Grade

Three pathological grading systems advocated by Perzin/Szanto, Spiro, and van Weert are currently used for adenoid cystic carcinoma (AdCC). In these systems, the amount or presence of the solid tumor component in AdCC specimens is an important index. However, the solid tumor component has not been well defined Morphologic distinction of high-grade adenoid cystic carcinoma from basaloid squamous cell carcinoma can be difficult. Equivocal diagnoses can mislead treatment. We have investigated the possibility that immunohistochemical staining for the presence of p63, a novel epithelial stem-cell regulatory pr *Adenoid cystic carcinoma (ACC) facts written by Charles P.

1. Introduction. Adenoid cystic carcinoma (AdCC) is a common histopathologicaltype of malignant salivary gland tumor. It is characterized clinically by a slow progression, by local recurrence, late distant metastasis, and ultimately fatal outcome [].Adenoid cystic carcinoma is histopathologically classified as grade I to III according to the predominant histological pattern; tubular. High-grade transformation of adenoid cystic carcinoma (adcc-HGT) represents an oncological event that is associated with increased biological aggressiveness of the tumor and adverse clinical outcome [ 1 ] Adenoid cystic carcinoma (ACC) is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% of cancers of all sites, of which, 10-15% are malignant [ 1, 2 ]. Though ACC is the most common malignant tumor of the submandibular, sublingual and minor salivary glands, it accounts for only 15% of parotid cancers [ 3 ] Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast, lacrimal gland, lung, brain, bartholin gland, trachea, and the paranasal sinuses.. It is the third-most common malignant salivary gland tumor overall (after mucoepidermoid.

  1. Adenoid Cystic Carcinoma (ACC) of Lung is a very rare and unusual form of cancer. It is typically observed in middle-aged and older adults. The tumor may be present in the lung tissue or within the bronchial airways. If it is present in the bronchial airways, it is called Adenoid Cystic Carcinoma of Bronchus

  3. Adenoid cystic carcinoma of the breast is a biphasic tumor comprised of a ductal / epithelial cell and myoepithelial / basaloid cell components. The ductal / epithelial cells are immunoreactive for low molecular weight keratins such as CK7 and CK8/18. The myoepithelial / basaloid cell component is positive for high molecular weight keratins.
  4. Adenoid Cystic Carcinoma (ACC) is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread

Adenoid cystic carcinoma (ACC) is an uncommon malignancy of secretory glands, which is characterized by slow growth kinetics and perineural invasion, and is among the rarer tumors for which little research has been performed and for which there are few treatment options for patients with advanced disease To classify all adenoid cystic carcinoma to be of high-grade malignancy is a practical approach, possibly regarded as pragmatic by some, but makes the concept of high-grade transformation, or dedifferentiation, possibly of less importance in cases of ADCC, contrary to, e.g. acinic cell carcinoma

High-grade transformation of adenoid cystic carcinoma (ACC) (previously referred to as dedifferentiation) is a rare phenomenon that does not fit into the traditional ACC grading schemes Adenoid cystic carcinoma is most common in the fifth and sixth decades of life. However, it can appear at virtually any age. The patient population in 1 recent review was reported to range from 10 to 96 years.4 Gender predilection is an inconsistent feature in the literature with some authors reporting a male predominance and others finding a female or no gender predilection.1,5-7 In. Adenoid cystic carcinoma (ACC), known as cylindroma in the past, is a variant of adenocarcinoma with distinct histopathologic and clinical features. ACC occurs most commonly in the salivary glands and, less commonly, at other sites such as the breast, skin, uterine cervix, upper aerodigestive tract, and lung The histologic appearance of adenoid cystic carcinoma is low grade, management of this malignancy is a challenge because of its insidious local growth pattern and lack of effency with chemotherapy or radiotherapy in metastatic disease. In other performed clinical trials, objective responses to any cytotoxic agent or regimen are infrequent. Common histologies were olfactory neuroblastoma (23%), squamous cell carcinoma (22%), and adenoid cystic carcinoma (17%). Advanced stage (T3 in 25% and T4 in 69%) and high-grade histology (51%) were common. Surgical procedures included endoscopic resection alone (45%), endoscopic resection with craniotomy (12%), or open resection (30%)
