Within the head, there is head associated lymphoid tissues (HALT) that contain the Harderian gland, lacrimal gland and other structures in the larynx or nasopharynx. (wikipedia.org)
Lacrimal gland inflammation in rats and mice can result from various causes, including retrobulbar bleeding trauma, infectious agents such as sialodacryoadenitis virus in rats, and autoimmune disease. (nih.gov)
Lacrimal gland inflammation should be diagnosed and assigned a severity grade whenever present. (nih.gov)
Petechial2
Endothelial cell damage and necrosis is believed to be responsible for the petechial hemorrhages and edema that accompany IBR. (iastate.edu)
Inflammation is differentiated from cellular infiltrates by the presence of other changes, such as edema, hemorrhage, degeneration, necrosis, or other evidence of tissue damage. (nih.gov)
Chronic1
Histologically, the lesions were characterized as lymphoplasmacytic and heterophilic, multifocal to coalescing, moderate, chronic conjunctivitis associated with hyperplasia and ectasia of the Harderian gland, and numerous parasites. (pvb.com.br)
Inflammation4
Hemorrhage secondary to other lesions (e.g., inflammation) should not be diagnosed separately unless warranted by severity. (nih.gov)
Cellular infiltrates can be distinguished from inflammation by the presence of other features of inflammation, such as tissue destruction, hemorrhage, fibrosis, edema, or additional types of leukocytes. (nih.gov)
Inflammation is differentiated from cellular infiltrates by the presence of other changes, such as edema, hemorrhage, degeneration, necrosis, or other evidence of tissue damage. (nih.gov)
The location of the inflammation within the gland (acini or duct) should be indicated in the pathology narrative. (nih.gov)
Infiltration Cellular1

Mammary gland1
At the end of two years, mammary gland fibroadenomas in females and thyroid follicular cell tumors in both sexes were the only tumors increased in acrylamide treated rats. (gpstoxpath.com)

Interstitium2
Harderian gland hemorrhage consists of variable numbers of extravasated blood cells in the gland interstitium and/or alveoli (Figure 1 and Figure 2). (nih.gov)
Small focal clusters of inflammatory cells in the interstitium are common incidental findings in the Harderian gland of rats and mice. (nih.gov)
Lesions1
Changes in the paraocular glands accompanying the ocular lesions which result from a deficiency of vitamine A. J Exp Med 38:25-32. (nih.gov)
Severity2
Harderian gland hemorrhage should be diagnosed with assignment of a severity grade. (nih.gov)
Harderian gland infiltrates should be diagnosed and assigned a severity grade, especially when there are treatment-related increases in incidence and/or severity. (nih.gov)
