Background Nodular lymphoid hyperplasia (NLH) of intestine is an extremely rare lymphoproliferative disorder of uncertain etiology. Usually, polyps benign lymphoid tissue are present in the intestinal mucosa. It may present as an asymptomatic or manifest with gastrointestinal symptoms such as abdominal pain, chronic diarrhea, occult bleeding or intestinal obstruction. NLH found in association w...

Repetitive topical applications of 2 micrograms 12-O-tetradecanoylphorbol-13-acetate (TPA) twice weekly for 37 to 52 weeks induced a sustained epidermal hyperplasia, hyperplasia of hair follicles, and increased dermal cellularity in SENCAR mice. In addition, after 52 weeks of protracted promoter treatment most animals developed generalized amyloidosis involving liver and spleen, as well as inte...

Enlarged peripheral lymph nodes (lymphadenopathy or lymphadenomegaly) can occur with lymphoid and plasma cell hyperplasia, inflammation, or lymphoid or metastatic neoplasia. Fine-needle aspiration (FNA) cytology of enlarged lymph nodes is relatively non-invasive and inexpensive, and with experience, often provides an accurate diagnosis. However, in some cases, special stains, biopsy, immunophen...
