What is follicular lymphoid hyperplasia in tonsils?
Lymphoid papillary hyperplasia (LPH) of the tonsils is a rare, benign disorder that is frequently accompanied by dysphagia. LPH is characterized by a papillary, papillomatous, or multiple polypoid gross appearance with reactive follicular hyperplasia covered by a non-atypical squamous epithelium [1–9].
Do tonsils have lymphoid follicles?
What are Tonsils? The luminal surface of the tonsils are covered with a stratified squamous epithelium (in common with the oral epithelia). The tonsils have many invaginations which form blind crypts. Below the epithelium, there are many lymphoid follicles beneath which have germinal centres like the lymph nodes.
Is follicular hyperplasia serious?
Prognosis. Typically follicular hyperplasia is categorized as a benign lymphadenopathy.
What are the symptoms of lymphoid hyperplasia?
Nodular lymphoid hyperplasia generally presents as an asymptomatic disease, but it may cause gastrointestinal symptoms like abdominal pain, chronic diarrhea, bleeding or intestinal obstruction. A diagnosis is made at endoscopy or contrast barium studies and should be confirmed by histology.
What is a lymphoid follicle?
Lymphoid follicles are small masses of tissues that contain aggregations of inflammatory cells, mainly B cells with some T cells and dendritic cells.
What is reactive lymphoid follicular hyperplasia?
Abstract. Background: Reactive lymphoid follicular hyperplasia is a benign proliferation of lymphoid follicles, which can develop wherever lymphoid tissue is present. We present the unique case of an RLFH that involved the radial nerve and presented as a peripheral nerve tumor.
What does follicular hyperplasia mean in tonsils?
4.1 Follicular lymphoid hyperplasia (FLH) Similar to pathologic findings in enlarged paediatric lymph nodes, the most common finding in removed tonsils is reactive follicular hyperplasia. Areas of active, mixed and chronic inflammation may be seen. 4.2 Active inflammation and peritonsillar
What is the difference between tonsillar lymphoid follicles and lymph nodes?
The tonsillar lymphoid follicles are similar to those in lymph nodes, with the observation that marginal zones are usually obscured except in florid follicular hyperplasia. The lymphoid cells infiltrating the epithelium of the crypts appear to be of marginal zone B-cell type, while most of those in surface epithelium are of T-cell type.1
What causes lymph node enlargement in follicular hyperplasia?
In follicular hyperplasia, the lymph node enlargement is primarily due to the increased number and size of the follicles [1, 2]. Germinal centers are expanded and follicles appear in different sizes and shapes and are surrounded by well-defined mantle zones.
What are the signs and symptoms of removed tonsils?
Similar to pathologic findings in enlarged paediatric lymph nodes, the most common finding in removed tonsils is reactive follicular hyperplasia. Areas of active, mixed and chronic inflammation may be seen. 4.2 Active inflammation and peritonsillar abscesses
