    Hydroa vacciniforme-like lymphoma is a recently recognized cutaneous T-cell lymphoma associated with Epstein-Barr virus. The disease is observed in children of Latin American or Asian ethnicity. The authors report the clinical, histopathological, and immunophenotypical features of 9 new Mexican patients (M:F = 2:1; mean age, 14.5 years; median age, 13.3 years; age range, 4-27 years), expanding on previous observations of this elusive disease. The most common clinical aspects were persistent facial edema with necroses and pitted scars. Histopathological analyses revealed variably dense lymphoid infiltrates with common angiodestructive features. Neoplastic cells expressed CD3 and cytotoxic markers in all cases and were constantly positive for Epstein-Barr virus (EBER-1). Expression of other markers was variable. Follow-up data revealed that all patients died within 6 months or less, thus showing a very aggressive course with poor prognosis.

    Hydroa vacciniforme-like lymphoma with primarily periorbital swelling: 7 cases of an atypical clinical manifestation of this rare cutaneous T-cell lymphoma.
    Am J Dermatopathol 2015 Jan;37(1):20-5

    Hydroa vacciniforme-like lymphoma (HVL) is a rare cutaneous T-cell lymphoma that is usually seen in children of Hispanic or Asian origin. Association between chronic latent Epstein-Barr virus infection in both hydroa vacciniforme (HV) and HVL has been demonstrated and has recently been categorized by the World Health Organization as one of the Epstein Barr virus-positive lymphoproliferative disorders of childhood. Patients with HVL present with a cutaneous rash characterized by edema, blisters, ulcers, and scars mainly seen on the face and extremities that mimic HV; however, unlike in HV, the lesions tend to be extensive and deeper and are associated with severe scarring, necrosis, and systemic manifestations.

    Epstein-Barr virus-associated hydroa vacciniforme-like cutaneous lymphoma in seven Chinese children.
    Pediatr Dermatol 2010 Sep-Oct;27(5):463-9
    Department of Dermatology, Beijing Children's Hospital, Capital Medical University, Beijing, China.
    Hydroa vacciniforme-like cutaneous lymphoma is a rare type of Epstein-Barr virus-associated lymphoma. We analyze clinicopathologic features of seven Chinese child patients with hydroa vacciniforme-like cutaneous lymphoma and determine the pathogenic association of Epstein-Barr virus with this disorder. Clinical, histologic, and immunohistochemical features were reviewed. Read More
    Primary cutaneous hydroa vacciniforme-like lymphoma with indolent clinical course: report of two cases and review of literature.
    Int J Surg Pathol 2013 Apr 17;21(2):161-8. Epub 2012 Jul 17.
    The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
    Primary cutaneous hydroa vacciniforme (HV)-like lymphoma is a rare, Epstein-Barr virus-associated cutaneous neoplasm characterized by photosensitive papulovesicular eruption and usually associated with poor prognosis. This report presents 2 cases of primary cutaneous HV-like lymphoma with unusual indolent clinical course and favorable prognosis during the follow-up periods of 2 and 3 years, respectively. Both patients presented with erythema, papulovesicles, scars, ulcerations, and edema on the face and extremities. Read More
    Hydroa Vacciniforme-Like EBV-Positive Cutaneous T-Cell Lymphoma, First Report of 2 Cases in Ecuador.
    Am J Dermatopathol 2016 May;38(5):e57-9
    Servicio de Patología, Hospital Metropolitano, Quito, Ecuador.
    Hydroa vacciniforme-like cutaneous lymphoma is a very rare Epstein-Barr virus positive peripheral T-cell lymphoma affecting Asian and Hispanic children and young adults with a defective cytotoxic immune response to EBV predisposing to the development of the disease. We report on 2 Ecuadorian patients with papulovesicular and ulcerated crusted lesions on the face, upper and lower extremities and abdomen, with aggressive clinical course and, in one case, a fatal outcome. The histological and molecular profiles (immunohistochemistry and in situ hybridization) established a diagnosis of hydroa vacciniforme-like Epstein-Barr virus-encoded small RNAs + cutaneous T-cell lymphoma in both cases.
