A rare case of congenital leiomyomatosis in a 2-year-old boy is presented. The plaque, composed of multiple small leiomyomata, showed positive staining for desmin, a muscle protein, indicating a smooth muscle origin.

Area of Science:

  • Dermatology
  • Pathology
  • Pediatrics

Background:

  • Congenital skin conditions require early diagnosis and management.
  • Leiomyomas are benign tumors originating from smooth muscle tissue.
  • Desmin is a key intermediate filament protein in muscle cells.

Observation:

  • A 2-year-old boy presented with a persistent plaque on his upper arm.
  • The plaque consisted of multiple, small (2-3 mm) smooth muscle tumors (leiomyomata).
  • These lesions appeared at 3 months of age and remained unchanged.

Findings:

  • Immunohistological examination revealed positive desmin staining within the leiomyomata.
  • This confirms the smooth muscle origin of the observed lesions.
  • The clinical presentation is considered unusual for this age group.

Implications:

  • This case highlights the importance of considering rare congenital smooth muscle tumors.
  • Understanding the immunohistochemical profile (desmin positivity) aids in diagnosis.
  • Further research is needed to determine the long-term prognosis and optimal management for such cases.
