Development of huge keloid at donor site and recurrent keloid at graft site after excision of pubic keloid followed by split-thickness skin graft: A case report.

INTRODUCTION

Keloids are the result of abnormal tissue scarring that occur after skin injuries leading to pain, psychological distress, and impaired quality of life. Despite the high recurrence rate after surgical treatment, excision is often inevitable for symptom control.

PATIENT CONCERNS

A 32-year-old female presented with a huge keloid on the pubic area accompanied by severe pain, pruritus, and infectious discharge. She also had multiple keloids on her chest and shoulders, indicating a strong predisposition to keloid formation.

INTERVENTIONS

While high potential for recurrence was anticipated, surgical excision was inevitable for symptom control. Complete keloid excision followed by split-thickness skin graft was performed.

DIAGNOSIS

Pathological report revealed keloid accompanied by ruptured epidermal inclusion cyst.

OUTCOMES

Although postoperative care was highly recommended for prevention of keloid recurrence, the patient refused any additional management due to her financial difficulties. At postoperative 8 months, mild degree of keloid or hypertrophic scar at marginal area of the graft was observed, suggesting the potential sign of keloid recurrence. The patient voluntarily discontinued the outpatient follow-up for 2 years, and then returned with huge keloid not only at the graft site but also at the donor site.

CONCLUSION

Keloid with inflamed epidermal inclusion cyst can cause severe pain where surgical excision is unavoidable, regardless of the high potential for recurrence. Additional postoperative care is necessary to prevent recurrence. Furthermore, attempts to minimize new keloid formation at the donor site after split-thickness skin graft, such as thin skin harvest or selecting the scalp as the donor site, should be considered.
