A rare caruncular dermoid tumor caused spontaneous bleeding in an 11-year-old girl. Surgical removal and reconstruction were successful, suggesting shared embryologic origins for the caruncle and eyelid.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Oculoplastics

Background:

  • Dermoid tumors are congenital choristomas, typically found in the orbit or eyelids.
  • Caruncular dermoids are uncommon, and their association with epibulbar bleeding is rare.
  • This case highlights a unique presentation of a dermoid tumor originating from the ocular surface.

Observation:

  • An 11-year-old female presented with a mass involving the caruncle and upper eyelid, accompanied by spontaneous epibulbar bleeding.
  • The mass required surgical excision, including reconstruction of the nasolacrimal system, eyelid margin, and conjunctiva.
  • Histopathologic examination confirmed the diagnosis of a dermoid tumor of the caruncle.

Findings:

  • The dermoid tumor originated from the caruncle and extended to the upper eyelid.

Related Experiment Videos

  • The tumor was associated with spontaneous epibulbar bleeding, an unusual complication.
  • Successful surgical management and reconstruction were achieved.

    • Implications:

    • This case underscores the importance of considering dermoid tumors in pediatric patients with eyelid masses and bleeding.
    • The caruncular origin and eyelid attachment suggest a potential shared embryologic development between the caruncle and the upper eyelid.
    • Further research into the embryogenesis of these structures may provide deeper insights into similar congenital anomalies.
