Multiple skin granular cell tumors can mimic keloids or dermatofibrosarcoma. Early detection and complete surgical removal are crucial for managing this rare condition.

Area of Science:

  • Dermatology
  • Oncology
  • Pathology

Background:

  • Granular cell tumors (GCTs) are rare neoplasms of neural crest origin.
  • Cutaneous GCTs can present with diverse clinical appearances.

Observation:

  • A 27-year-old male presented with multiple cutaneous granular cell tumors.
  • One GCT mimicked a dermatofibrosarcoma or keloid clinically.
  • Histological examination revealed significant peritumoral fibrosis in multiple lesions.

Findings:

  • Granular cell tumors can present as keloid-like lesions.
  • Peritumoral fibrosis is a notable histological feature in some cutaneous GCTs.
  • Differential diagnosis for keloidal lesions should include granular cell tumors.

Implications:

  • Complete surgical excision is recommended for cutaneous GCTs.
  • Regular patient follow-up is essential for early detection of new or recurrent tumors.
  • Increased awareness of GCTs' varied presentations can improve diagnostic accuracy.
