A rare case of subungual malignant melanoma, a cancer under the fingernail, was diagnosed in a 43-year-old male. Surgical removal was successful, with no remaining cancer cells found.

Area of Science:

  • Oncology
  • Dermatology
  • Pathology

Background:

  • Subungual malignant melanoma is a rare but aggressive form of skin cancer.
  • Early diagnosis and treatment are crucial for patient outcomes.
  • The Hutchison sign is a key clinical indicator of subungual melanoma.

Purpose of the Study:

  • To present a rare case of subungual malignant melanoma.
  • To highlight the clinical presentation and diagnostic challenges.
  • To emphasize the importance of prompt surgical intervention.

Main Methods:

  • Clinical presentation of a 43-year-old male with a black, dystrophic left middle finger nail plate.
  • Physical examination revealing a positive Hutchison sign.
  • Surgical management involving disarticulation at the proximal interphalangeal joint.

  • Histopathological confirmation of malignant melanoma.

    • Main Results:

    • Histopathology confirmed malignant melanoma of the subungual region.
    • Surgical resection achieved tumor-free margins.
    • The patient's condition was successfully managed with limb-sparing surgery.

    Conclusions:

    • Subungual malignant melanoma requires high clinical suspicion, especially with characteristic signs like the Hutchison sign.
    • Prompt and adequate surgical resection is essential for effective treatment.
    • This case underscores the importance of recognizing rare presentations of melanoma.
