Toilet seat dermatitis (TSD) is a localized form of dermatitis that commonly occurs in the buttocks and upper posterior aspect of the thigh in school-going children. Previously, it was mostly seen due to allergic contact dermatitis to wood, but recently, many other allergens in toilet seats along with the possibility of irritant contact dermatitis (ICD) to detergents were reported.
Six cases diagnosed clinically as atopic dermatitis per Hanifin and Rajka criteria presented with posterior thigh dermatitis. Patch testing using the Indian Standard Series, toilet seat scrapings, and detergents was conducted.
Patch testing showed negative results at 48, 96, and 168 hours, including lesional site testing. Symptomatic management, including topical steroids and later tacrolimus, was administered, coupled with counselling on toilet seat cover use, with a follow-up after four weeks. Lesions showed resolution and reduced itching.
This study's limitation lies in its small sample size from a single geographic area.
Lesion resolution through topical treatment and toilet seat avoidance, support a diagnosis of contact dermatitis; however, the role of atopy remains crucial, suggesting a complex interplay. Larger studies are needed for a comprehensive understanding of this dermatological condition.
马桶座圈皮炎（TSD）是一种局限性皮炎，常见于学龄儿童的臀部和大腿后侧上部。以前，主要是由于对木材的过敏性接触性皮炎所致，但最近，有报道称马桶座圈中存在许多其他过敏原，同时还存在对洗涤剂的刺激性接触性皮炎（ICD）的可能性。
6例根据Hanifin和Rajka标准临床诊断为特应性皮炎的患者出现大腿后侧皮炎。使用印度标准系列、马桶座圈刮屑和洗涤剂进行斑贴试验。
斑贴试验在48、96和168小时显示阴性结果，包括皮损部位试验。给予了包括外用类固醇及随后的他克莫司在内的对症治疗，同时就使用马桶座圈盖进行了咨询，并在四周后进行了随访。皮损消退，瘙痒减轻。
本研究的局限性在于其样本量小且来自单一地理区域。
通过局部治疗和避免使用马桶座圈使皮损消退，支持接触性皮炎的诊断；然而，特应性的作用仍然至关重要，提示存在复杂的相互作用。需要进行更大规模的研究以全面了解这种皮肤病状况。
