What does lymphoid aggregates in colon mean?

Lymphoid aggregate/infiltrate: A collection of B cells, T cells, and supporting cells, present within the stroma of various organs. The term can be used to describe endogenous lymphoid tissue or acquired lymphoid tissue.

Is lymphoid aggregate cancer?

Most prominent lymphoid aggregates are made up of non-cancerous cells. However, in some instances, your pathologist may perform additional tests such as immunohistochemistry and flow cytometry to confirm that the cells are not a type of cancer called lymphoma.

What is a lymphoid nodule in the colon?

Intestinal nodular lymphoid hyperplasia (NLH) is a benign lymphoproliferative disease characterized by a diffuse or focal hyperplasia of lymphoid follicles along the intestine due to an accumulation of nonmalignant lymphoid cells in the gut mucosa (2).

Is a lymphoid aggregate a polyp?

Lymphoid polyps (present in 15% of patients) are hyperplastic submucosal lymphoid aggregates, most likely due to a nonspecific infection (exposure to bacteria and viruses). Submucosal lymphoid tissue is prominent in children, particularly in the distal ileum (Peyer patches).

What is a lymphoid polyp?

A lymphoid polyp is an often benign, focal proliferation of gut associated lymphoid follicles. Lymphoid polyps are rarely found in adults and are usually found in terminal ileum or rectum. These polyps are usually asymptomatic though possible association with development of malignant lymphoma has been described.

Does everyone have lymphoid aggregates?

Basal small lymphoid follicles and aggregates were present in 25% of cases. The mean total lymphoid follicles and aggregates per biopsy was 0.59 ± 0.32 for study cases and 0.31 ± 0.21 for controls (P = . 005) (Table 3).

What is lymphoid polyp?

What causes lymphoid aggregate?

What are lymphoid polyps?

What causes lymphoid hyperplasia?

Lymphoid hyperplasia is an increase in the number of normal cells (called lymphocytes) that are contained in lymph nodes. This most often happens when there is an infection with bacteria, viruses, or other types of germs and is part of the body’s reaction to the infection.

Are polypoid polyps cancerous?

Approximately one quarter were considered non-neoplastic—hyperplastic, mucosal, and inflammatory polyps. Little evidence can be found to support a contention that any of these lesions predispose to the development of cancer; origin of carcinoma in such polyps is believed to be a rare event.
