Misdiagnosed interdigital melanoma, initially treated as a benign condition, led to aggressive tumor progression and metastasis. Early detection and proper diagnosis of acral lentiginous melanoma are crucial for better patient outcomes.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Interdigital spaces are prone to various cutaneous conditions, often benign.
  • Pigmented lesions in this area can be challenging to diagnose, with traumatic hematoma being a common consideration.

Observation:

  • A case of misdiagnosed interdigital melanoma presented as a benign lesion.
  • The patient underwent curettage, mistaking the melanoma for a hemangioma, leading to uncontrolled tumor progression.

Findings:

  • Acral lentiginous melanoma, an aggressive skin cancer, was misdiagnosed due to its unusual interdigital location.
  • Delayed diagnosis resulted in tumor progression, lymph node metastasis, and a generally poor prognosis.

Implications:

  • Highlights the critical importance of including acral lentiginous melanoma in the differential diagnosis of interdigital pigmented lesions.
  • Emphasizes that early detection and simple excision of melanoma in this location can significantly improve patient prognosis and survival.
  • Underscores the potential for severe consequences when life-threatening conditions are overlooked in favor of less severe, unconfirmed diagnoses.
