Peutz-Jeghers Polyps.--Peutz-Jeghers polyposis is an autosomal dominant syndrome characterized by multiple benign GI hamartomatous
polyps, mucocutaneous pigmentation, and tumors of ovary or testis resulting from mutations in the serine-threonine kinase (STK) 11 tumor suppressor gene located on chromosome band 19p13.3 in approximately 50% of the families with Peutz-Jeghers polyposis.

lesion," International Journal of Gynecological Pathology, vol.
Because they are composed of abnormal cells and tissue proliferations found in the location of their origin, here the tonsil, we agree that these tumors are reasonably hamartomatous
The history of the patient revealed that a circumoral pigmentation had been detected at the age of 2.5 years and that the patient was referred to a department of pediatric gastroenterology when he was 4 years old at which time he was diagnosed to have PSJ upon findings during endoscopic investigation which revealed presence of three rectal hamartomatous
polyps and ultrasonographic (USG) findings which showed multiple paraaortic, mesenteric, hypoechoic lymph nodes.
Instead of being driven by mutational changes and genomic instability, CPFEs are thought to arise from a combination of nongenetic causes: endothelial damage, viral-induced growth, microthrombi aggregation, and hamartomatous
polyps at the ascending colon were also reported.
thymoma (EHT) is a benign tumor that occurs with extreme rarity in the lower neck.
Other frequent lesions related to CS are hamartomatous
polyps of the digestive tract, fibrocystic disease of the breast, uterine leiomyoma, and macrocephaly [5,8].
Bronchoalveolar dysgenesis during the first trimester results in adenomatoid hamartomatous
proliferation of terminal bronchiolar units (hence its former name).
The nonneoplastic polyps include hyperplastic, juvenile, hamartomatous
, inflammatory, and lymphoid polyps.
