Acral lentiginous melanoma (ALM), a rare skin cancer, can be mistaken for a vascular ulcer. Prompt biopsy of non-healing ulcers is crucial for early diagnosis and improved survival rates.
Area of Science:
- Dermatology
- Oncology
- Vascular Surgery
Background:
- Acral lentiginous melanoma (ALM) is a rare melanoma subtype.
- ALM commonly occurs on distal extremities and can mimic other conditions.
- Early misdiagnosis of ALM can delay critical treatment.
Observation:
- A case study of a 68-year-old male smoker with hypertension, diabetes, and dyslipidemia presenting with intermittent claudication and a heel ulcer.
- Despite wound care and revascularization, the ulcer failed to heal.
- Biopsy confirmed acral lentiginous melanoma.
Findings:
- Histopathological examination revealed melanoma.
- Surgical excision of the melanoma was performed.
- The resulting wound was closed with a split-thickness skin graft.
Implications:
- This case highlights the importance of considering rare diagnoses like ALM in non-healing ulcers.
- Biopsies are essential for non-healing ulcers, even after vascular interventions.
- Timely diagnosis and treatment of ALM significantly impact patient prognosis and survival rates.
