Title : Coalescing tender nodules on the anterior chest: An atypical presentation of hidradenitis suppurativa


Hidradenitis suppurativa (HS) is an inflammatory skin condition that is characterized by inflamed nodules and abscesses that can form sinus tracts under the skin, typically in skin fold areas, that are tender and drain pus. Efficient diagnosis and early intervention is critical for this condition, as initiating treatment can keep the lesions under control and prevent worsening of nodules that can cause significant discomfort and permanent scarring. Here, we present a case of an unusual presentation of hidradenitis suppurativa in a 41-year-old male who presented to the emergency department with a chief complaint of a tender, purulent anterior chest cutaneous mass, which pathology later confirmed was consistent with an HS lesion. While HS typically occurs in regions with skin folds, this case illuminates an atypical presenting area – the anterior chest wall. Thus, clinicians should keep HS on the differential for such lesions, as the location of the affected area should not rule in or out HS as a diagnosis.

Audience Take Away Notes:

  • Hidradenitis suppurativa is an inflammatory skin condition
  • Hidradenitis suppurativa can present in atypical areas of the body
  • Clinicians should consider Hidradenitis Suppurativa on the differential diagnosis for any lesions that suggest follicular occlusion is involved in the pathogenesis, regardless of location on the skin
