Intra-oral angiosarcomas are rare head and neck tumors. This case highlights the diagnostic challenges of gingival angiosarcoma, a rare cancer with varied histopathology.

Area of Science:

  • Oncology
  • Oral Pathology
  • Head and Neck Surgery

Background:

  • Angiosarcomas are rare malignant vascular tumors.
  • Intra-oral angiosarcomas, particularly in the gingiva, are exceptionally rare.
  • Diagnosis can be challenging due to rarity and diverse histopathological features.

Purpose of the Study:

  • To report a rare case of intra-oral angiosarcoma.
  • To discuss the diagnostic difficulties of gingival angiosarcomas.
  • To highlight the utility of immunohistochemistry in diagnosing such tumors.

Main Methods:

  • Case presentation of a 70-year-old male with a mandibular alveolar crest tumor.
  • Clinical diagnosis of a tumor.
  • Histopathological examination revealing mixed vascular, carcinomatous, and sarcomatous elements.

  • Immunohistochemical analysis using CD31, AE1-AE3, and vimentin.

    • Main Results:

    • The tumor presented as a clinically diagnosed lesion of the alveolar crest.
    • Histopathology showed a complex tumor with vascular proliferation, carcinoma, and sarcoma.
    • Immunohistochemistry confirmed the cellular origins of the proliferating cells.

    Conclusions:

    • Gingival angiosarcoma is a rare entity requiring a high index of suspicion.
    • Accurate diagnosis relies on comprehensive histopathological and immunohistochemical evaluation.
    • This case underscores the importance of considering rare differentials in intra-oral tumors.
