Pustules on the back possibly triggering toxic-shock syndrome

Area of Science:

• Medicine
• Infectious Diseases
• Dermatology

Background:

• Toxic-shock syndrome (TSS) is a severe, multi-system illness often associated with Staphylococcus aureus or Streptococcus pyogenes infections.
• While typically characterized by shock, TSS can present atypically, posing diagnostic challenges.

Observation:

• A previously healthy 28-year-old Japanese male presented with sudden high fever, conjunctival hyperemia, vomiting, diarrhea, and a diffuse macular erythroderma.
• Physical examination revealed pustules on the back that spontaneously resolved, followed by scalded skin on the face and limb extremity desquamation by day 10.
• Laboratory findings indicated multiple organ failures, yet the patient maintained stable circulatory dynamics throughout the illness.

Findings:

• The clinical presentation, particularly the delayed desquamation, led to the diagnosis of toxic-shock syndrome (TSS).
• This case underscores that TSS can manifest with significant systemic symptoms and organ dysfunction without overt circulatory shock.
• Characteristic skin findings, such as desquamation, can be crucial diagnostic clues, even when appearing later in the disease course.

Implications:

• Clinicians should consider TSS in the differential diagnosis of acute febrile illnesses with rash and organ dysfunction, irrespective of shock.
• Awareness of atypical TSS presentations, including delayed desquamation, is vital for timely diagnosis and management.
• This case emphasizes the importance of thorough dermatological examination in patients with suspected severe infections.
