# Epidermal Inclusion Cysts of the Head and Neck: A One-Year Tertiary Care Experience With Emphasis on the Periauricular Region and Review of Literature

## TL;DR

This paper studies epidermal inclusion cysts in the head and neck, focusing on their occurrence near the ear and treatment outcomes.

## Contribution

The study emphasizes periauricular EICs and provides insights from a tertiary care center's experience.

## Key findings

- Periauricular EICs were the most common in the head and neck region (27.3%).
- Complete surgical excision led to no recurrence and satisfactory cosmetic outcomes.

## Abstract

Introduction: Epidermal inclusion cysts (EICs) are common benign lesions of epidermal origin, often presenting as soft, fluctuant subcutaneous swellings. The head and neck region is one of the commonest sites of its occurrence, with the periauricular area being a distinct subset because of its anatomical and cosmetic considerations. This study highlights the clinical profile, management, and outcomes of periauricular EICs at a tertiary care center.

Materials and methods: A retrospective observational study was conducted over one year, from February 2024 to February 2025, in the Department of Otorhinolaryngology at a tertiary care center in Eastern India. Twenty-two FNAC-confirmed EIC cases in the head and neck region were analyzed, and among them, six cases located in the periauricular area were discussed in detail.

Results: The patient cohort ranged from nine to 51 years (median 21.5 years), with equal gender distribution. Periauricular EIC (n = 6, 27.3%) was the most common. All patients underwent complete surgical excision with no recurrence observed during the follow-up period of three to six months. Cosmetic outcomes were generally satisfactory in all cases.

Conclusions: Periauricular EICs, while benign, require careful clinical evaluation due to their location and aesthetic implications. Complete surgical excision remains the treatment of choice, with low recurrence and excellent prognosis.
