Abstract

Infectious eczematoid dermatitis (IED) is defined as an acute, eczematous eruption that occurs secondary to autosensitization to purulent drainage from a primary infected site. The condition is believed to develop when bacterial products, most often the result of Staphylococcal or Streptococcal species, act as haptens and stimulate an immune response. IED typically manifests as a plaque with associated vesicles and pustules surrounding drainage from a central infectious source, or as oozing, erythema, crusting, and scaling spreading peripherally from a central infectious source. Management of IED includes both targeting the causative primary infection and suppressing the immune response producing a hypersensitivity reaction. This report details two cases. Case 1 describes a common presentation of tinea pedis. Case 2 is that of a 28 year-old-male who presented with an acute onset tender, pruritic, weeping rash after wearing boots for two straight days, and who was subsequently diagnosed and treated for IED.

Highlights

Case 1 is a male patient who presented with chronic scaling of the pedal interdigital spaces associated with mild intermittent pruritus. (Figure 1A and 1B)
Case 2 is of a 28 year-old-male that presented with an acute onset erythematous eruption bilaterally on the feet
In case 1, the patient had a symbiotic relationship with a non-complicated tinea pedis infection, with fungal culture revealing

Introduction

Case 1 is a male patient who presented with chronic scaling of the pedal interdigital spaces associated with mild intermittent pruritus. (Figure 1A and 1B). Case 1 is a male patient who presented with chronic scaling of the pedal interdigital spaces associated with mild intermittent pruritus. Erythematous eruption with interdigital and subdigital purulence overlying edematous toes of a male patient after two straight days without removing boots.
