A typical case of Cowden disease is presented. This is rare mucocutaneous disease, genetically determined, with multiple organ system involvement in which a malignancy, particularly of breast and thyroid gland, may develop. The disease can be diagnosed in its early stages by gingival and cutaneous manifestations. We emphasize that the dentist may be the first health care professional who recognizes the syndrome, which is a crucial step to prevent and cure the predictable malignancy.

: PTEN hamartoma tumor syndrome (PHTS) has evolved into an umbrella term for a range of syndromes, characterized by loss-of-function variants in the phosphatase and tensin homolog (PTEN) tumor suppressor gene on chromosome 10q23.31. This can result in a lifelong tumor predisposition in patients.

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.

Objective: This study evaluates the utility of word embeddings, generated by large language models (LLMs), for medical diagnosis by comparing the semantic proximity of symptoms to their eponymic disease embedding ("eponymic condition") and the mean of all symptom embeddings associated with a disease ("ensemble mean").
Materials And Methods: Symptom data for 5 diagnostically challenging pediatric diseases-CHARGE syndrome, Cowden disease, POEMS syndrome, Rheumatic fever, and Tuberous sclerosis-were collected from PubMed. Using the Ada-002 embedding model, disease names and symptoms were translated into vector representations in a high-dimensional space.

Rationale: This study aims to present a case of cerebellar dysplastic ganglioneuroma, which is commonly referred to as Lhermitte-Duclos disease (LDD). Furthermore, the study aims to provide an extensive review of the essential aspects of LDD, thereby providing essential information for its accurate diagnosis and effective treatment.
Patient Concerns: A 54-year-old woman was admitted with symptoms of headache, facial numbness, and a visible cerebellar mass.

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.
