Boils/Styes
Published in Charles Theisler, Adjuvant Medical Care, 2023
Small and painful pus-filled bumps (about the size of a pea) under the skin are known as boils. They are typically red, swollen, and tender and often increase in size over time. Most boils are caused by a staphylococcus infection in a hair follicle or a sweat gland. A boil that occurs on the eyelid is called a stye. Most boils and styes heal on their own within one to three weeks.

The eyelids, being thin and sensitive, may become quite warm during infection or when traumatized. Thermography is good at detecting these conditions, sometimes appearing quite abnormal when the visible appearance of the lids is almost normal. A stye (infection of a meibomian gland in the lids) shows up well in facial thermograms (Figure 11.21b).

Chalazia and styes are different things. Chalazia occur because of a blocked meibomian gland. They are not usually painful unless infected. Styes, on the other hand, are infected hair follicles on the lid margin. They present with a painful yellow lesion around the lid margin. Styes are usually self-limiting, resolving within 1 or 2 weeks – this can be accelerated by warm compresses. Occasionally they may require antibiotics. An infected chalazion can resemble a stye, so consider this possibility in ‘recurrent styes’.

Interestingly, the term with the best fit to our regression model was stye with r2 = 0.89 with a peak during the summer. The seasonality of the term stye has been previously reported, though with a lower goodness-of-fit (r2 = 0.19) and association with temperature-related environmental factors.10 The study by Leffler and colleagues was conducted using Google Trends data from 2004 to 2008, and we suspect that the increase in use of Google searches over the past decade may have contributed to a greater number of queries for the word stye, thereby decreasing the noise and revealing the periodic nature of the query (eSupplement 3). Internet-based surveillance tools such as Google Trends, become more powerful at revealing clinically meaningful patterns the more frequently they are used. Clinically, these findings may allow primary care practitioners and eye-care providers to recommend increasing simple interventions such as warm compresses and lid hygiene as we approach the summer months for patients with a predilection for styes.

A stye (hordeolum) is an infection localized to the eyelid that can present as a tender, erythematous, swollen lesion. It is usually caused by an inflammatory response induced by an acute infectious source, with most cases caused by Staphylococcus aureus.1 Styes are known to be associated with skin conditions like rosacea, blepharitis, seborrheic dermatitis, and systemic conditions such as diabetes and hyperlipidemia.2,3 While styes are a common diagnosis for patients with a painful eye,4 its incidence and prevalence are unknown. This highlights an important reality: the incidence or prevalence of common conditions is relatively unknown, especially those with straightforward treatments. When looking at the case of styes, it is unlikely that valuable time and resources would be devoted to conducting an epidemiological study of its prevalence, when its treatment is simple.

Lesions affecting the eyelid present in a variety of ways. Eyelid lesions may be classified as neoplastic (benign or malignant), inflammatory, congenital, infectious, or traumatic.1 Neoplastic lesions are usually benign.2 The most common benign etiologies of eyelid lesions include hordeolum (stye), chalazion, and xanthelasma. Less common malignant lesions include basal cell carcinoma, squamous cell carcinoma, sebaceous carcinoma, and melanoma.3 Typically, eyelid lesions that do not necessitate immediate biopsy may be diagnosed and monitored based on clinical appearance and characteristic features; however, a biopsy with histopathological analysis may be indicated if the lesion begins changing size and/or character or presents with concerning findings from the outset.4 We present a case of a 51-year-old man who was diagnosed with HIV/AIDS after shave biopsy of a presumed chalazion on the eyelid margin revealed Kaposi sarcoma (KS).
