Cowden's disease is an inheritable multiple neoplastic syndrome represented by benign and malignant lesions of skin, digestive tract, mucosae, breast and thyroid. The syndrome, first described by Lloyd and Dennis in 1963, includes benign lung lesions, described in the literature only as hamartomas. The unusual condition of our case consists of multiple and bilateral lipomatous lesions of the lung and of adipose colonic polyps, diagnosed respectively by video assisted mini-thoracotomy and by endoscopic biopsies.

Cowden Syndrome and Oral Lesions: A Case Report Using MLPA.

BACKGROUND Cowden syndrome is a genetic disorder that predisposes individuals to cancer and is characterized by hamartomas derived from 3 germ layers. Although the clinical signs can be pathognomonic, diagnosis is often aided by biopsies, histopathological examination of oral and cutaneous lesions, and genetic studies, including multiple ligation-dependent probe amplification (MLPA). CASE REPORT We report a case of a 35-year-old woman who manifested with multiple lesions in the buccal mucosa, dorsum of the tongue, and gums, along with papillomatous papules on her facial skin and the dorsal surfaces of her hands.

Importance: A subset of thyroid cancers develops in a setting of a known hereditary cancer-associated syndrome. Understanding the population prevalence of thyroid cancer-associated syndromes is important to guide germline genetic testing and clinical management.
Objective: To estimate the prevalence of the major thyroid cancer-associated syndromes in the United States using the All of Us Research Program (AoU) data.
Cancer and disease profiles for PTEN pathogenic variants in Japanese population.

A germline alteration in the PTEN gene causes a spectrum of disorders conceptualized as PTEN hamartoma tumor syndrome (PHTS), which show high risk of tumor development and a highly variable and complex phenotype. The diagnosis of PHTS is established in a proband by identification of a heterozygous germline PTEN pathogenic variant on molecular genetic testing. In this study, to understand more PTEN-associated clinical phenotype and PHTS in a Japanese population, we extracted 128 germline PTEN rare variants from 113,535 adult Japanese registered in Biobank Japan (BBJ), and categorized 29 pathogenic/likely pathogenic variants in 30 individuals (0.

Article Synopsis
- PTEN hamartoma tumour syndrome (PHTS) is a hereditary cancer syndrome mainly caused by PTEN gene variants, significantly increasing breast cancer risk for female carriers (up to 80%).
- A study tracked breast biopsies of 14 females with these gene variants over 28 years, finding high rates of breast cancer diagnoses (85.7%) with an average initial diagnosis age of 41.6.
- The research highlights that breast cancer in PHTS does not have distinctive features, emphasizing the need for healthcare professionals to familiarize themselves with these cases for better early recognition and management.
