Giant Vulvar Epidermoid Cyst in an Adolescent Girl

الملخص EN

Introduction.

Vulvar cyst in adolescent girls is very uncommon.

Epidermoid cyst can be seen in many sites including face, trunk, and extremities but its occurrence in vulva is uncommon.

This is the first case of epidermoid cyst of vulva reported in an adolescent girl.

Case.

A 17-year-old, adolescent girl admitted to our gynecology outpatient clinic with a complaint of painful and palpable mass in her vulva.

On examination, a giant mass located in left vulva and labia majora with 11 cm in diameter was seen.

The magnetic resonance imaging (MRI) showed a well-defined cystic mass without contrast enhancement.

The surgery was advised to the patient and the pathologic examination of mass revealed vulvar epidermoid cyst.

Discussion.

Vulvar cysts generally grow slowly and the main etiologies are vulvar trauma and surgical interventions including episiotomy and female circumcision in some culture.

The exact treatment is total surgical excision and pathologic examination.

MRI is an important imaging modality for detection of extension to deep perineal tissue and localization of mass in vulva especially in giant ones.

Conclusion.

Although vulvar mass in adolescents is rare, the epidermoid cyst with benign origin should be kept in mind.
