Multiple hamartoma syndrome (Cowden's disease)

Area of Science:

• Oncology
• Genetics
• Dermatology

Background:

• Cowden's disease, a rare genetic disorder, is characterized by hamartoma development.
• Previous research has documented various clinical manifestations of this syndrome.

Observation:

• Four male patients diagnosed with Cowden's disease were studied.
• The patients presented with a spectrum of previously reported symptoms associated with the syndrome.

Findings:

• Key unreported findings included multiple cutaneous trichilemmomas, cafe-au-lait spots, and cutaneous squamous cell carcinoma.
• Additional significant observations were pathologic fracture, craniomegaly, probable malignant lung tumor, retinal glioma, optic disk and retinal drusen, and pseudotumor cerebri.
• The patients also exhibited a mediastinal mass and multiple small papillomatous lesions in the esophagus, stomach, and duodenum.

Implications:

• This case series expands the known clinical spectrum of Cowden's disease.
• Early recognition of these diverse manifestations is crucial for timely diagnosis and management.
• Further research into the genetic underpinnings and long-term prognosis of these findings is warranted.
