Abstract
Background

Hidradenitis suppurativa is a chronic recurrent systemic inflammatory disease that mainly involves large skin folds. It develops when pilosebaceous units become blocked, leading to the formation of painful nodules, abscesses, fistulas, and scarring. The impact of this disease on quality of life is great.

Objectives

To describe the prevalence and clinical features of hidradenitis suppurativa in patients treated at Hospital Italiano de Buenos Aires and determine the frequency of comorbidities and time to diagnosis in this population.

Material and methods

Retrospective descriptive cross-sectional study. Information was extracted from the computerized clinical records of all patients with a diagnosis of hidradenitis suppurativa managed in Hospital Italiano de Buenos Aires between July 2012 and October 2017.

Results

Our initial search of the records yielded 180 cases; the diagnosis was confirmed in 66 cases. Sixty-five percent of the patients were women, and the mean age was 37 years. The prevalence of this diagnosis was 0.02%.

The armpits, vulva, and groin were the locations most frequently affected. Smoking, overweight, and obesity were the most commonly recorded concomitant conditions.

Male sex and perianal and gluteal locations were associated with severity.

Time until diagnosis varied widely, ranging from diagnosis at the first visit in some cases to as long as 142 months and 21 visits.

Conclusions

Our findings are consistent with the literature on hidradenitis suppurativa. This is the first Argentinian study to describe the prevalence of this disease as well as the concomitant conditions found and the rate of diagnostic error.

Resumen
Antecedentes

La hidradenitis supurativa es una enfermedad sistémica inflamatoria crónica y recurrente, que afecta, principalmente, los grandes pliegues. Se origina por la oclusión de las unidades pilosebáceas, con la consecuente formación de nódulos dolorosos, abscesos, fístulas y cicatrices, con un alto impacto en la calidad de vida.

Objetivos

Describir prevalencia, características clínicas, frecuencia de comorbilidades y latencia diagnóstica, en pacientes con hidradenitis supurativa atendidos en el Hospital Italiano de Buenos Aires.

Materiales y métodos

Estudio retrospectivo descriptivo de corte transversal. Se relevó la información de las historias clínicas electrónicas de todos los pacientes con diagnóstico de hidradenitis supurativa atendidos en el Hospital Italiano de Buenos Aires entre julio de 2012 y octubre de 2017.

Resultados

La búsqueda inicial en nuestra base de datos arrojó 180 historias clínicas. En 66 casos se confirmó el diagnóstico. Un 65% eran mujeres. La edad media fue 37 años. La prevalencia fue de 0,02%.

Las áreas más afectadas fueron las axilas, la vulva y las ingles. El tabaquismo y el sobrepeso u obesidad fueron las comorbilidades más frecuentes.

El sexo masculino y las localizaciones perianal y glútea, se asociaron a casos más graves.

El lapso al diagnóstico tuvo un intervalo muy amplio, desde un diagnóstico en la primera consulta, hasta una demora de 142 meses y 21 consultas previas.

Conclusiones

Nuestros resultados se encuentran dentro de los valores de la literatura. Este es el primer trabajo de Argentina que describe la prevalencia, las comorbilidades y el error diagnóstico en la hidradenitis supurativa.
