Adenoid cystic carcinoma (ACC) of the lacrimal glands is an extraconal malignancy usually originating from the orbital lobe of the lacrimal gland. The text also includes diagnostic advances in immunohistochemistry, flow cytometry, gene microarray, and the polymerase chain reaction. These are summarized in a separate chapter on orbital biopsy. There are a few different types of lacrimal gland cancer including lymphoma and adenoid cystic carcinoma. Recent findings: Debulking of the orbital lobe of the lacrimal gland may offer improved control rates in dacryoadenitis without compromise of tear film function. 66.1 and 66.2 ); of these, most are epithelial and the remainder lymphoproliferative tumors ( Figs.

Lacrimal gland masses can be classified into two broad groups - inflammatory (~50%) and neoplastic, either lymphoma (25%) or salivary gland type tumors (~25%). Because tumor stage at presentation may be associated with prognosis, it should be considered when treatment is planned. Staging is a means to identify how serious a particular cancer tumor is by giving it a numerical classifications as compared to other similar types of tumors.

Stage at diagnosis in salivary gland adenoid cystic carcinoma ranged from I to IV, and all lacrimal gland cases presented with N0M0 disease with T-stage ranging from 2a to 4c (Table 1). Overall, more than 55% (range, 55-100%) of tumors are malignant, tend to be locally invasive, and have a high recurrence rate. A tumor is an abnormal growth of body tissue. Tumors of the salivary glands are some of the most complex tumors known. T stage was retroactively determined where possible using extent of disease and collaborative stage staging codes for tumor size and location following the classification protocol determined by the American Joint Committee on Cancer; tumors were defined as T1 for size less than 2 cm with no extraglandular extension, T2 for size between 2 and 4 cm with no extraglandular extension, T3 for size … About half of lacrimal gland tumors are benign.

A lacrimal gland tumor is a tumor in one of the glands that produces tears. Because the lacrimal and salivary glands share similar characteristics, the American Joint Committee on Cancer classification (AJCC) has aligned the classification with those of the salivary gland.5 Recently, Jack Rootman, MD, and Valerie A. The final diagnosis was primary ductal adenocarcinoma of lacrimal gland, staging T4N0M0. Here are more details on each part of the TNM system for lacrimal gland cancer: Using the TNM system, the "T" plus a letter and/or number (0 to 4) is used to describe the size and location of the tumor. Some stages are also divided into smaller groups that help describe the tumor in even more detail. The lacrimal glands are the glands that secrete tears and are located above and to the side of the eye.

The results are combined to determine the stage for each person. It typically presents in adults between 30-50 years old; the median age is 40 years old. The most common tumor histology in our series was squamous cell carcinoma. [7][8][4] Pathology. It accounts for 25% of all epithelial lacrimal gland tumors. Oropharynx (p16-) Hypopharynx 12. The glands produce a fluid that cleans and protects the surface of the eyelid. White, MD, published an update of this classification, and adjusted the size of the lacrimal gland to the TNM classification of the salivary tumors. Parenchymal and other Organs.

The lacrimal gland is located under the outer part of each eyebrow. Lacrimal gland masses can be classified into two broad groups - inflammatory (~50%) and neoplastic, either lymphoma (25%) or salivary gland type tumors (~25%). Purpose: To review the clinical presentation, treatment, and prognosis of patients with malignant mixed tumor (carcinoma ex pleomorphic adenoma) of the lacrimal gland.
