    A 67-year-old male presented with a rapidly growing left auricle neoplasm. Surgical resection was successful, with no recurrence or metastasis observed during an 8-month follow-up, indicating fibrosarcoma is treatable with surgery.

    Area of Science:

    • Oncology
    • Pathology
    • Surgical Oncology

    Background:

    • A 67-year-old male patient presented with a left auricle neoplasm.
    • The tumor had been present for two months and rapidly increased in size over the last 10 days.

    Observation:

    • The neoplasm measured approximately 2.0 cm × 2.0 cm, with a smooth, hard, painless, and immobile surface.
    • Biopsy and postoperative pathological reports indicated a spindle cell sarcoma, specifically fibrosarcoma, characterized by specific cellular morphology and collagen matrix changes.
    • Immunohistochemical staining results were Vimentin (+), with other markers negative (CD99, Bcl-2, CD34, SMA, Des, HMB45, MelanA, S-100, CK).

    Findings:

    • Total resection of the left auricle was performed under local anesthesia.
    • The resected tumor demonstrated destruction of cartilage.

  • Postoperative follow-up for 8 months revealed no local recurrence or distant metastasis.

    • Implications:

    • Complete surgical excision is a viable primary treatment for localized auricular fibrosarcoma.
    • Early detection and surgical intervention can lead to favorable outcomes, even in rapidly growing neoplasms.
    • This case highlights the importance of histopathological and immunohistochemical analysis for accurate diagnosis and treatment planning of rare sarcomas.
