Overview

Case report highlights delayed diagnosis of plantar melanoma in an elderly patient, stressing the need for careful examination.

Key Points

  • This report aims to highlight the characteristics and challenges in diagnosing plantar melanoma, specifically akral lentijinöz melanom (ALM) in older patients.
  • Presented a case of a 74-year-old woman with a painful lesion on the plantar surface after a thorn injury.
  • Conducted dermatoscopic examination revealing specific features like heterogeneous pigmentation and ulceration.
  • Performed histopathological analysis confirming ALM with a Breslow thickness of 15 mm.
  • PET/CT showed increased FDG uptake in the right inguinal-femoral lymph nodes, but no malignancy was found upon histopathological evaluation of excised nodes.
  • Wide local excision was performed, and no recurrence was detected during one year of follow-up.
