Cutaneous angiosarcoma mimicking xanthoma: a challenging histopathologic diagnosis with important consequences

Area of Science:

• Dermatopathology
• Oncology
• Histopathology

Background:

• Cutaneous angiosarcoma presents diverse histopathologic features.
• Uncommon variants include epithelioid, clear cell, and signet-ring cell types.

Observation:

• This report describes an extraordinary case of cutaneous angiosarcoma.
• Nearly all neoplastic cells exhibited a xanthomatous (foamy) appearance.
• The case was analyzed using histopathology and immunohistochemistry.

Findings:

• The study focuses on a rare variant: cutaneous angiosarcoma with xanthomization.
• Detailed histopathologic and immunohistochemical analysis was performed.
• Differential diagnosis for this foamy cell angiosarcoma is discussed.

Implications:

• This case expands the understanding of cutaneous angiosarcoma variants.
• Accurate histopathologic diagnosis is crucial for differentiating this rare tumor.
• Knowledge of this variant aids in clinical and pathological assessment of skin neoplasms.
