Summary

Trauma can lead to dystrophic calcinosis cutis, a condition where calcium deposits form in the skin. This case highlights transepidermal elimination of calcium following minor abrasions.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Dystrophic calcinosis cutis is a rare condition characterized by calcium salt deposition in damaged tissues.
  • Trauma is a known, albeit infrequent, precipitating factor for calcinosis cutis.

Observation:

  • An 8-year-old boy presented with multiple papules in the inguinal folds after sustaining abrasions during a soccer game.
  • The papules had soft centers and contained white particles, indicative of calcification.

Findings:

  • Biopsy confirmed the diagnosis of calcinosis cutis.
  • Histopathological examination revealed transepidermal elimination of calcium, a mechanism by which the body attempts to expel calcified deposits.

Implications:

  • This case underscores the potential for even minor trauma to trigger dystrophic calcinosis cutis in susceptible individuals.
