Giant Scapular Vascular Eccrine Spiroadenomas: A Rare Case Report

Area of Science:

• Dermatology
• Oncology
• Surgical Pathology

Background:

• Eccrine spiradenoma is a benign dermal appendage tumor.
• Malignant variants, such as giant vascular eccrine spiradenoma (GVES), are rare.
• GVES represents a malignant transformation of eccrine spiradenoma.

Observation:

• A case of GVES is presented with unique characteristics.
• The neoplasm was notably large and located on the scapula.
• The scapular region typically has sparse vascularization.

Findings:

• The giant scapular vascular eccrine spiradenoma exhibited aggressive histological features.
• Despite its size and location, complete surgical excision was achieved.
• Postoperative follow-up revealed a favorable prognosis.

Implications:

• This case expands the understanding of GVES presentation and behavior.
• The successful management of a large GVES in a challenging location is demonstrated.
• Further research into the oncogenesis and treatment of GVES is warranted.
