Hydroa Vacciniforme-Like T-Cell Lymphoma: A Further Brazilian Case

Area of Science:

• Pediatric Oncology
• Dermatology
• Infectious Diseases

Background:

• Hydroa vacciniforme-like lymphoma (HVLC) is a rare, often fatal Epstein-Barr virus (EBV)-associated lymphoproliferative disorder.
• HVLC primarily affects children in Asia, Mexico, and South America, presenting with skin lesions mimicking benign Hydroa vacciniforme (HV).

Observation:

• A case of HVLC is presented in a 12-year-old girl of indigenous Amazonian descent.
• This represents the second reported case of HVLC in Brazil.

Findings:

• The patient's cutaneous manifestations were consistent with HVLC, a condition distinct from benign HV due to its systemic nature and poor prognosis.
• The genetic and geographic origins of the patient may offer insights into potential risk factors or disease variations.

Implications:

• This case underscores the importance of recognizing HVLC in endemic and non-endemic regions.
• Further research into EBV-driven lymphoproliferative disorders in diverse pediatric populations is warranted.
• Early diagnosis and understanding of HVLC pathogenesis are critical for improving patient outcomes.
