Surgical Excision: An Effective Modality for Intradermal Melanocytic Nevus

Abstract

Objective: To evaluate the effectiveness of fusiform surgical excision of intradermal melanocytic nevus and to document the aesthetic outcome of post-excisional surgical scar.

Study Design: Prospective longitudinal study.

Place and Duration of Study: Tertiary Care Hospital, Gujranwala Pakistan, from Apr to Oct 2021.

Methodology: Patients with intradermal melanocytic nevus were enrolled after informed consent. Close-up photographs of the nevus and the site post-excision were taken. Local anaesthesia was injected with 2% Lignocaine with Adrenaline under aseptic measures. An elliptical incision with scalpel blade-15 was made around the nevus. The length of the incision was almost three times its width. Nevus and the involved tissue were removed to its full depth. A visual analogue scale was used to assess the scar cosmesis.

Results: A total of 37 intradermal melanocytic nevi, were included in the study. The size of the intradermal melanocytic nevus ranged from 0.5-2cm with a duration of 3-10 years. The mean visual analogue scar scale on day 5 of surgical excision was 7.23±1.423, and on day seven was 5.37±0.575. Surgical sutures were removed on day 5 in 13(35.1%) cases and day-7 in 24(64.9%) cases.

Conclusion: Surgical excision is an effective treatment modality for intradermal melanocytic nevus.
