Cowden's disease with associated malignant melanoma

Area of Science:

• Genetics
• Dermatology
• Oncology

Background:

• Cowden's disease (multiple hamartoma syndrome) is a rare autosomal-dominant genodermatosis.
• Characterized by widespread hamartomas (benign growths) affecting skin, mucous membranes, and internal organs.

Observation:

• Skin manifestations include verrucous papules, perioral and acral lesions, and papillomatosis.
• These hamartomas are associated with an increased risk of various benign and malignant tumors.

Findings:

• This report details the second documented case of Cowden's disease associated with malignant melanoma.
• The findings underscore a potential link between Cowden's disease and melanoma development.

Implications:

• Patients with Cowden's disease require a high index of suspicion for associated malignancies.
• Early detection and management of tumors, including melanoma, are crucial in Cowden's disease patients.
