[Parvovirus B19 in Adolescents and Adults: A Case Series of Clinical Mimicry]

Area of Science:

• Infectious Diseases
• Dermatology
• Pediatrics

Background:

• Parvovirus B19 is the causative agent of erythema infectiosum.
• The virus can present with a wide range of clinical manifestations.
• Recognizing its diverse presentations is crucial for accurate diagnosis.

Purpose of the Study:

• To highlight the diagnostic challenges posed by Parvovirus B19.
• To illustrate the varied clinical presentations of Parvovirus B19 infection.
• To emphasize the importance of considering Parvovirus B19 in the differential diagnosis of exanthemas and vasculitis.

Main Methods:

• A case series approach was utilized.
• Five distinct clinical cases of Parvovirus B19 infection were analyzed.
• Diagnostic pathways and initial misdiagnoses were reviewed.

Main Results:

• Three cases presented with papulo-purpuric gloves and socks syndrome and petechial exanthema, initially misdiagnosed as drug eruption, scarlet fever, and autoimmune thrombocytopenia.
• Two cases presented as leukocytoclastic vasculitis, with Parvovirus B19 infection confirmed upon further investigation.
• These cases demonstrate Parvovirus B19's ability to mimic other dermatological and systemic conditions.

Conclusions:

• Parvovirus B19 is a significant mimic of various diseases.
• Healthcare providers should maintain a high index of suspicion for Parvovirus B19 in patients with unexplained exanthemas and vasculitis.
• Timely diagnosis of Parvovirus B19 infection is essential to avoid delayed or incorrect treatment.
