With a yearly incidence of one in one million, they represent only 10% of orbital space-occupying lesions. The age of presentation of lacrimal gland tumors depends on the specific subtype of tumor, but overall these tumors can occur at any age. Epithelial tumors, like pleomorphic adenomas and adenoid cystic.

In any case, there are 3 major tumors that affect the lacrimal gland: orbital lymphoma, pleomorphic adenoma of the lacrimal gland, and adenoid cystic carcinoma of the lacrimal gland.

ACC is a high-grade malignancy accounting for 29 % of all epithelial lacrimal gland tumours and as many as 50 % of all malignant epithelial lacrimal gland neoplasms. Its incidence peaks in the 4th decade

The lacrimal gland is a bilobed eccrine secretory gland, which is situated in the superotemporal orbit. The 2 lobes of the lacrimal gland, the orbital lobe and the much smaller palpebral lobe, are separated anatomically by the lateral horn of the levator aponeurosis. Only the palpebral lobe can be visualized in the superior fornix on lid eversion Lacrimal sac tumors are rare, but their early recognition and management is imperative as the tumors can be locally invasive and potentially life threatening. Tumors can be benign or malignant, and 55% of lacrimal sac tumors are malignant. Mortality rates for malignant tumors vary with stage and type, but fatal outcomes are reported in up to a third of patients

Pleomorphic adenoma of the lacrimal gland (PALG), also known as benign mixed tumor, is a rare tumor of the lacrimal gland.[1] PALG typically presents with unilateral painless proptosis. Affected individuals may be unaware of the onset of proptosis because it is typically gradual in onset. It is important to differentiate PALG from adenoid cystic carcinoma (ACC) because of their vastly. Summary. The lacrimal apparatus consists of the lacrimal gland, which secretes the aqueous layer of the tear film, the lacrimal sac, into which the tears drain, and the nasolacrimal duct, through which the tears drain into the nose. Inflammation of the lacrimal gland is called dacryoadenitis and is commonly caused by viral or bacterial infections. The condition typically presents with. The lacrimal drainage apparatus consists of the superior and inferior canaliculi, common canaliculus, lacrimal sac, and nasolacrimal duct (). 1 Tears collect in the lacrimal sac before draining into the nasolacrimal duct and the inferior meatus of the nasal cavity. 2 Lacrimal sac and duct tumors are rare. 3 The most common presenting clinical symptoms of lacrimal sac and duct tumors are.

Lacrimal gland tumors are rare and constitute a wide spectrum of different entities ranging from benign epithelial and lymphoid lesions to high-grade carcinomas, lymphomas, and sarcomas with large differences in prognosis and clinical management. The symptoms and findings of a lacrimal gland lesion are a growing mass at the site of the lacrimal gland, including displacement of the eyeball. Dacryoadenitis is an infection of the lacrimal gland. Sudden onset of soft tissue swelling that is maximum over the outer portion of the upper lid margin is typical. Occasionally, the eyeball is erythematous and the eyelid swollen, and the patient can have remarkable constitutional symptoms. The location of the swelling is a distinguishing.

Pleomorphic adenoma

The fact that the lacrimal gland has a standing population of lymphocytes and plasma cells—which are not, however, organized into lymph nodes (as may be seen in the parotid gland)—may explain the relative frequency of the development of idiopathic dacryoadenitis and lymphoid tumors of the gland The main lacrimal gland is located in the superior lateral portion of the anterior orbit. Directly posterior to the orbital rim is a concavity within the orbital plate of the frontal bone that forms the lacrimal fossa . The lateral horn of the levator aponeurosis divides the lacrimal gland into an orbital an Tumours of the lacrimal gland are relatively rare. The incidence in various studies has been found to be between 5 to 7%.

Adrenal cancer is a rare cancer that begins in one or both of the small, triangular glands (adrenal glands) located on top of your kidneys. Adrenal glands produce hormones that give instructions to virtually every organ and tissue in your body. Adrenal cancer, also called adrenocortical cancer, can occur at any age Technique. The examination should be carried out with the highest-frequency transducer possible. Usually, 5-12-MHz wide-band linear transducers (median frequency, 7-7.5 MHz or more) are used (, 9).In assessment of large tumors and lesions located in deep portions of the glands, 5-10-MHz transducers may be useful (, 12).Probes with a median frequency above 10 MHz may be useful in. Adenoid cystic carcinoma (ACC) of the lacrimal apparatus, which includes the lacrimal gland, lacrimal sac, and nasolacrimal duct, has a poor long-term disease-free survival (DFS) profile that is complicated by complex orbital anatomy and aggressive recurrence rates. ACC is the most common malignant histology of the lacrimal gland, with survival rates of less than 50% at 5 years and 20% at 10. termined by the tumor location (Fig. 1).

Lacrimal gland biology remains poorly understood. Here, we establish organoids from mouse and human lacrimal gland that can serve as study subjects for the lacrimal gland in vitro. In addition, we describe the human lacrimal gland at the single-cell level, which provides a platform for future studies The lacrimal gland is located in the supratemporal orbit. Two lobes exist, the orbital and the palpebral. The palpebral lobe is visualized easily by upper lid eversion. This eccrine secretory gland is responsible for the formation of the aqueous layer of the tear film. By definition, dacryoadenitis is an inflammatory enlargement of the lacrimal. All tumors showed benign histopathological features. However, two patients had tumor activity in surgical margin in the initial resection, favoring development of loco-regional recurrence in one of the patients.
