Background:
Lobular keloid appears to be a consequence of hypertrophic inflammation secondary to ear piercings performed under unsterile conditions. We wish to understand the pathogenesis of lobular keloids and report operative outcomes with a literature review.
Methods:
A retrospective review identified 40 cases of lobular keloids between January, 2005 and December, 2010. Patient records were reviewed for preclinical factors such as presence of inflammation after ear piercing prior to keloid development, surgical management, and histopathologic correlation to recurrence.
Results:
The operation had been performed by surgical core extirpation or simple excision, postoperative lobular compression, and scar ointments. Perivascular infiltration was noted in intra- and extra-keloid tissue in 70% of patients. The postoperative recurrence rate was 10%, and most of the patients satisfied with treatment outcomes.
Conclusion:
Histological perivascular inflammation is a prominent feature of lobular keloids. Proper surgical treatment, adjuvant treatments, and persistent follow-up observation were sufficient in maintaining a relatively low rates of recurrence.
