An Expanding Large Acrochordon on the Labia Majora Requiring Surgical Intervention

TL;DR

A woman had a large skin tag on her labia majora that grew significantly over 18 months and required surgery due to discomfort and appearance concerns.

Contribution

Presentation of a rare case of a giant acrochordon requiring surgical intervention for both diagnostic and cosmetic reasons.

Findings

The lesion grew from 1 mm to 65 mm in 18 months, which is unusually large for an acrochordon.

Histologic analysis confirmed the benign nature of the lesion, ruling out malignancy.

Surgical excision was performed to address aesthetic concerns and prevent complications like ulcerations.

Abstract

Acrochordons, also known as fibroepithelial stromal polyps or skin tags, are benign outgrowths of the skin that commonly occur in intertriginous regions and rarely grow larger than 1-5 mm in diameter. Benign acrochordons are common and can be difficult to distinguish from other benign stromal tumors and malignant growths. A 47-year-old woman with a body mass index of 26.6 kg/m² and no major predisposing factors presents with a giant acrochordon measuring 65 x 30 mm on the right labia majora. The lesion grew from 1 mm to 65 mm in approximately 18 months. The mass is associated with aesthetic dissatisfaction, itchiness, redness, and inner thigh friction that can lead to ulcerations. Histologic analysis is necessary for diagnostic confirmation. Aesthetic concerns and the importance of ruling out malignancy were factors that led to treatment with complete surgical excision.
