Angioleiomyomas are rare benign tumors typically found on lower extremities. This case highlights an unusual angioleiomyoma presentation on the ear helix in a male patient, confirmed by histology.

Area of Science:

  • Dermatology
  • Pathology
  • Surgical Oncology

Background:

  • Angioleiomyomas are benign tumors originating from smooth muscle tissue, predominantly vascular in nature.
  • They typically present as subcutaneous nodules, most commonly on the lower extremities, with a higher incidence in females.
  • Rarely, angioleiomyomas occur in the head and neck region, posing diagnostic challenges due to their unusual location.

Observation:

  • A 66-year-old male presented with a three-year history of a progressively enlarging, brownish, elastic, non-tender nodule on the helix of his left auricle.
  • Physical examination confirmed a 15 x 15 x 6 mm ovoid lesion.
  • No other similar lesions were noted on the face, neck, or extremities.

Findings:

  • Histological examination of the excised tumor confirmed the diagnosis of angioleiomyoma.

  • The tumor exhibited characteristic features of smooth muscle proliferation and vascular components.

    • Implications:

    • This case underscores the importance of considering angioleiomyomas in the differential diagnosis of auricular tumors, even in atypical locations.
    • Surgical excision with clear margins is the standard treatment for angioleiomyomas.
    • Further research into the etiology and specific risk factors for angioleiomyomas in unusual locations may be warranted.
