Balloon Cell Melanoma and Its Metastasis, a Rare Entity

Area of Science:

• Oncology
• Dermatology
• Pathology

Background:

• Balloon cell melanoma (BCM) is a rare neoplasm.
• Metastasis from BCM is exceptionally infrequent.
• Understanding BCM metastasis is crucial for accurate diagnosis.

Observation:

• This review analyzes published cases of balloon cell melanoma metastasis.
• A novel case of BCM metastasis is presented.
• All reviewed cases exhibit similar histopathological features.

Findings:

• Histopathological similarity is consistent across BCM metastasis cases.
• Initial melanoma location, patient age, and sex show variability.
• BCM metastasis can manifest as nonpigmented skin lesions.

Implications:

• Dermatologists and dermatopathologists must consider BCM in differential diagnoses.
• Awareness of BCM metastasis potential aids in early detection.
• Recognizing BCM metastasis, even as nonpigmented lesions, is clinically significant.
