A Case Presentation of Three Polypoid Melanomas With Divergent Features

Area of Science:

• Dermatology
• Oncology

Background:

• Polypoid melanoma, a subtype of nodular melanoma, is the most aggressive form of cutaneous melanoma.
• Its rapid vertical growth and varied features complicate clinical diagnosis.

Observation:

• Presents three cases of polypoid melanoma initially misdiagnosed as benign lesions or non-melanoma cancers.
• Highlights the diverse clinical presentations of polypoid melanomas.

Findings:

• Emphasizes the critical role of annual skin examinations for early detection.
• Underscores the necessity of complete lesion biopsies for accurate diagnosis.
• Stresses the importance of collaboration with experienced dermatopathologists.

Implications:

• Increases awareness of this rare and deadly melanoma subtype.
• Advocates for a broad differential diagnosis approach for suspicious skin lesions.
• Promotes timely diagnosis and treatment for improved patient outcomes.
