Area of Science:

  • Dermatology
  • Pathology

Background:

  • Cutaneous horns are compacted keratin growths often linked to underlying pathologies, including malignancy.
  • Differential diagnosis includes pseudohorns, which mimic horns but are tumors.

Observation:

  • A novel type of pseudohorn was observed.
  • This pseudohorn was composed of hair, dried serum, and inflammatory exudate.

Findings:

  • The observed pseudohorn was associated with an underlying basal cell carcinoma.
  • This finding expands the definition of pseudohorns beyond tumor-only compositions.

Implications:

  • This expands the differential diagnosis for cutaneous horns and pseudohorns.
  • Recognizing this pseudohorn type is crucial for accurate diagnosis and management of skin conditions.
