Localized Versus Generalized Granuloma Annulare: A Retrospective Review of 407 Patients.

ABSTRACT:

Background

Granuloma annulare has been linked to diabetes, dyslipidemia, thyroid disease, collagen vascular disease, malignancies, infectious hepatitis, and systemic infections. However, these associations have not been systematically investigated when categorized by its clinical variants.

Objective

To evaluate disease associations of localized and generalized granuloma annulare.

Methods

In total, 407 granuloma annulare patients from 1989 to 2019 were retrospectively reviewed, categorized by clinical variant (localized or generalized), age (pediatric or adult), and diagnostic method (clinical or histologic). Descriptive statistical analyses and multivariate logistic regression analysis were performed. Fisher's exact tests were conducted to produce unbiased probability values.

Results

Overall, 75.2% of the study sample was female, 47.2% had dyslipidemia, 24.8% were diabetic, and 24.6% had thyroid disease. Dyslipidemia (OR 2.15, CI 1.95-2.35, P < .001), diabetes (OR 1.16, CI 1.01-1.31, P = .041), and histologic diagnosis (OR 2.08, CI 1.21-3.52, P = .007) were associated with increased risk of GGA compared to LGA. When stratified by adult versus pediatric cases, dyslipidemia and diagnostic method remained significant, but diabetes did not.

Conclusions

Evaluating granuloma annulare by its clinical variants may help to determine disease associations with each variant.

Project description:BackgroundGranuloma annulare is a chronic noninfectious granulomatous skin condition with variable clinical presentations. Generalized granuloma annulare, defined as widespread disease with >10 skin lesions, accounts for 15% of all cases. Numerous associated diseases have been controversially discussed, most importantly diabetes mellitus, dyslipidemia, thyroid disease, malignancy and systemic infections.ObjectivesThe objective of our study is to describe disease characteristics, treatment outcome and associated diseases in patients treated at the Department of Dermatology of the University Hospital Zurich during the last 20 years.MethodsThe hospital database was searched for patients with generalized granuloma annulare in the last 20 years (January 1, 1998, to December 31, 2017). Overall, 61 patients, 14 males and 47 females, were included in our study. The mean age was 58 years at first consultation. The diagnosis was verified clinically and histologically.ResultsGeneralized granuloma annulare occurred at a mean age of 55 years, more commonly in females. Pruritus was absent in 51% of all patients. Metabolic diseases including diabetes mellitus, hypercholesterinemia and hypertriglyceridemia were present in 10.5, 8.2 and 4.9%, respectively. Thyroid disease was present in 9.8% and malignant disease in 23%, including colorectal cancer, lymphoproliferative disease, squamous cell carcinoma of the esophagus, basal cell carcinoma and gynecological malignancy. Therapy was initiated in 92%, while second- and third-line therapy was performed in 70 and 39%, respectively. Benefit during therapy (e.g., full and partial remission) was achieved in 39.3% during first-line, in 39.4% during second-line and in 33.8% during third-line treatment. Topical corticosteroids were the most commonly prescribed treatment, mostly leading to stable disease (46.6%). Combined full and partial remission occurred in a large proportion of patients receiving UVA1 (45%), PUVA (63.6%) and intralesional triamcinolone acetonide (100%).ConclusionsGeneralized granuloma annulare is a mostly asymptomatic and benign disease with a strong tendency for treatment resistance. We suggest to screen all patients for dyslipidemia, thyroid disease and malignant disease. While randomized trials are needed, we suggest topical corticosteroids as the first-line treatment, intralesional triamcinolone acetonide for persistent solitary lesions and, if further treatment is needed, UVA1 or PUVA.
