Rationale:
Epidermoid cyst (EC) is a common clinical condition and it can be filled with keratinized material. EC often represents painless, slow progressive growth, and single cyst. The cyst is usually 1 to 5 cm in size. Giant epidermoid cysts on the buttock area are extremely rare, and reports of giant epidermoid double cysts on the buttock are even rarer.
Patient concerns:
This paper reports a patient with a painless mass was on the left buttock.
Diagnosis:
A giant epidermoid double cysts with infection in a left buttock paranal location.
Interventions:
The mass was surgically removed.
Outcomes:
The patient recovered well after surgical treatment and currently has no recurrence.
Conclusion:
For patients with EC, MRI is recommended as a routine examination before surgery in order to detect the variation and extent of the cyst early. This lays a foundation for the complete resection of the lesion during the operation. The review of relevant literature will hopefully be helpful to clinicians.
