Ocular Involvement Preceded the Onset of Cutaneous Lesions in Hydroa Vacciniforme-Like Lymphoproliferative Disorder: A Case Report.

PURPOSE: To report a case of ocular involvement associated with hydroa vacciniforme-like lymphoproliferative disorder (HVLPD). CASE REPORT: A 10-year-old HVLPD boy suffered conjunctivitis, interstitial keratitis, and anterior uveitis sequentially during the whole course. Interestingly, this case manifested initially only with ocular findings, which preceded 1 year earlier than the onset of cutaneous lesions. And his later ocular findings occurred simultaneously with cutaneous lesions. The patient was treated with oral prednisone, ganciclovir, and light protection. Topical corticosteroid drops used to control ocular inflammation. Since then, he has not had any flares of ocular inflammation, and the cutaneous lesions improved. Although corneal nebula had been formed, the vision was still good. CONCLUSION: Our case was supportive of ocular involvement in HVLPD. Ophthalmologists should be aware of ocular involvement in HVLPD could be preceded the onset of cutaneous lesions, and prudently perform a careful ophthalmic examination at regular intervals to limit long-term sequelae.

Hydroa Vacciniforme-like Lymphoproliferative disorder in an adult invades the liver and bone marrow with clear pathological evidence: a case report and literature review.

BACKGROUND: Hydroa Vacciniforme-like Lymphoproliferative Disorder (HV-LPD) is the name given to a group of Epstein-Barr virus (EBV)-associated diseases. It resembles hydroa vacciniforme (HV), the rarest form of photosensitivity, and is a T-cell disorder associated with an Epstein-Barr virus infection. The majority of diagnosed cases occur in East Asia and South America. It is rare in the United States and Europe. Multiple studies have revealed the clinical manifestation of an enlarged liver, but no gold standard such as pathology has yet supported this as a clinical sign of HV-LPD. CASE PRESENTATION: Here, we report a case of a 34-year-old Asian female with definite liver invasion. The patient had complained of a recurring facial rash for many years. The patient was admitted to the hospital because of an enlarged liver. After hospitalization, she was given an EB virus nucleic acid test. The EB virus nucleic acid test was positive, and pathological examination suggested that HV-LPD had invaded the skin, bone marrow, and liver. After being given antiviral treatment, the patient's symptoms were mitigated. CONCLUSIONS: Our case confirms the liver damage was caused by HV-LPD and the effectiveness of antiviral treatment.

Distinguishing histologic clues to diagnosis are discussed, and important molecular advances are described. Key prognostic indicators that may assist clinicians with timely and appropriate management options are presented.

Hydroa vacciniforme-like cutaneous T-cell lymphoma in a child: A case report.

RATIONALE: Hydroa vacciniforme (HV)-like T-cell lymphoma is a rare malignancy in childhood associated with Epstein-Barr virus infection. PATIENT CONCERNS: A 6-year old girl presented with complaint of 3-year history of recurrent skin lesions, 3 months of fever accompanied by cough for 8 days. DIAGNOSES: Skin biopsy revealed a HV-like lymphoma presentation and positive signals of EBER were detected by in situ hybridization. TCR-γ gene monoclonal rearrangement was present. A HV-like cutaneous T-cell lymphoma was diagnosed. INTERVENTIONS: The girl was treated with cyclosporine and CHOP. OUTCOMES: The girl's condition had been stable for 6 months. LESSONS: Our case highlights the necessity for taking the HV-like lymphoma as a differential diagnosis especially when a patient manifests as recurrent skin lesions accompanied by systemic involvement.

Photodermatoses: Kids are not just little people.

Photodermatoses are a group of skin disorders caused by abnormal reaction to ultraviolet radiation. Photodermatoses are divided into four groups: (1) immunologically mediated photodermatoses; (2) chemical- and drug-induced photodermatoses; (3) photoaggravated dermatoses; and (4) hereditary photodermatoses. This contribution discusses differences in the approach and diagnosis of pediatric and adult patients with suspected photodermatoses, focusing on immunologically mediated photodermatoses and chemical- and drug-induced photodermatoses.

Hydroa vacciniforme-like lymphoma: a case report from India.

We report a 14-year-old Indian boy who presented with a history of weight loss, fever, facial edema, and a relapsing papulovesicular eruption on the face and limbs for 1 year. Histopathology of the skin showed dense lymphoid infiltrate from dermis to subcutaneous fat. Immunohistochemistry of this lymphoid infiltrate was CD3, CD8, CD56, CD57, Granzyme B, TIA, and Epstein Barr virus LMP1. The histopathology and immunohistochemistry were consistent with the diagnosis of hydroa vacciniforme-like T-cell lymphoma. The child responded remarkably to oral steroids but relapsed on tapering doses. CHOP (Cyclophosphamide, Adriamycin, Vincristine, and Prednisolone) chemotherapy was initiated in view of systemic involvement to which he showed some response, however, the disease relapsed again. He then had a rapidly progressive disease and ultimately succumbed to his illness. This is the first case of hydroa vacciniforme-like T-cell lymphoma being reported from this subcontinent.

Hydroa vacciniforme-like lymphoma: a chronic EBV+ lymphoproliferative disorder with risk to develop a systemic lymphoma.

Hydroa vacciniforme-like lymphoma (HVLL) is an Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disorder of childhood that occurs mainly in Central and South America and Asia. We present the clinicopathological features of 20 Mexican children with HVLL with a median age of 8 years at diagnosis (range, 1-15). All patients presented with skin lesions involving sun-exposed areas, but not exclusively. Fever, lymphadenopathy, and hepatosplenomegaly were often observed. Most patients were treated with immunomodulators and/or immunosuppressive agents, resulting in temporary remission. For 13 patients follow-up was available for a median of 3 years (range, 1 month-13 years). Three patients with long follow-up (9-13 years) are alive with disease. Four patients died, 2 after developing systemic lymphoma. Histologically, the skin showed a predominantly angiocentric and periadnexal Epstein-Barr early RNA+ lymphoid infiltrate with variable atypia and subcutaneous involvement. Fifteen patients showed a T-cell phenotype (12, αß; 2, γδ; 1, silent phenotype) and monoclonal T-cell receptor-γ rearrangements, whereas 6 exhibited a natural killer (NK)-cell phenotype. Four patients had hypersensitivity to mosquito bites. One patient showed both phenotypes. HVLL is an EBV-associated lymphoproliferative disorder of αß-, γδ-, or NK-cell phenotype with a broad clinical spectrum, usually prolonged clinical course, and risk for progression to systemic disease.

Primary cutaneous hydroa vacciniforme-like lymphoma with indolent clinical course: report of two cases and review of literature.

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. Skin biopsies revealed epidermal vesicle with small- to medium-sized atypical lymphoid cells infiltrating in the dermis and subcutis. The lymphoid cells were strongly immunoreactive to CD8 and CD56. The Epstein-Barr virus genomes were also found in both skin biopsies. By genetic analysis, one of patients showed T-cell receptor-γ gene clonal rearrangement. The patients underwent glucocorticoid treatment and obtained remarkable clinical improvement with regression of skin lesions. No sign of recurrence and extracutaneous manifestation was found during the period of follow-up. A long-term follow-up is suggested to be performed to inspect the progression for this tumor.

Efficacy of ω-3 polyunsaturated fatty acids for the treatment of refractory hydroa vacciniforme.

Hydroa vacciniforme (HV) is a rare photodermatosis. Several therapies, with sometimes severe side effects, have been used in isolated cases. We report a case of refractory HV successfully treated with dietary fish oil rich in ω-3 polyunsaturated fatty acids.

Antiviral therapy in children with hydroa vacciniforme.

Hydroa vacciniforme is a rare, usually quite severe, photo-dermatosis. Association with Epstein-Barr virus infection and a possibly increased risk of lymphoproliferative malignancy have been demonstrated. We describe here four patients with Epstein-Barr virus-associated hydroa vacciniforme treated with acyclovir/valacyclovir therapy with a good clinical response. The children were reported to have less fatigue, fewer eruptions, less scarring, and increased ability to spend time outdoors without provoking new eruptions. This was also in agreement with clinical observations. However, one patient progressed into an anaplastic lymphoma kinase-1-negative anaplastic large-cell lymphoma in the upper jaw. This was preceded by an increase in EBV viral load. Acyclovir/valacyclovir therapy is a safe treatment. Further studies are required to confirm these results.

Hydroa vacciniforme in an adolescent girl.

Hydroa vacciniforme (HV) is a rare photosensitivity disorder with onset in childhood. Recurrent vesicles, bullae and crusting occur on sun-exposed skin that heals with vacciniform scarring. This rare disorder is hereby reported in an adolescent girl who developed a severe episode of hydroa vacciniforme on a hot sunny day during harvesting season. She had repeated episodes afterwards in succession until she was appropriately sun-screened. Her lesions healed without scarring because of early reporting, short-lived episodes, early diagnosis and response to appropriate therapy.

Epstein-Barr virus-associated lymphoproliferative lesions presenting as a hydroa vacciniforme-like eruption: an analysis of six cases.

BACKGROUND: There are many reports of patients with a severe hydroa vacciniforme (HV)-like eruption in which cutaneous lesions occur in both sun-exposed and non-exposed areas, unlike in true HV. Several patients have died from a malignant haematological neoplasm. In most cases, a latent Epstein-Barr virus (EBV) infection has been detected in the skin lesions. OBJECTIVES: To describe the clinical and laboratory features of six additional patients with an EBV-associated HV-like eruption. METHODS: The clinical, histological and immunohistochemical features were reviewed. T-cell receptor gamma gene rearrangements were studied using polymerase chain reaction (PCR) and heteroduplex analysis. In-situ hybridization was performed to detect mRNA for EBV in skin biopsy specimens. PCR was performed to screen for EBV infection in the skin lesions of three patients and blood of two patients. Photoprovocation with repeated ultraviolet (UV) A exposure was performed in three patients. RESULTS: The severity of the skin lesions and the clinical course varied among the patients. Skin lesions were induced by repeated UVA exposure in three patients and a latent EBV infection was demonstrated in the photoprovoked lesions. CONCLUSIONS: Three different clinical courses were found in six patients with an HV-like eruption associated with chronic EBV infection: (i) spontaneous remission; (ii) clearing after photoprotection; and (iii) continuous recurrence irrespective of sun exposure. It is possible that there are two patterns of HV-like eruption associated with chronic EBV infection. One is characterized by recurrent necrotic papulovesicles of the face and the other by nodules and facial swelling. It was demonstrated that the skin lesions could be triggered by repeated UVA exposure in the patients showing recurrent necrotic papulovesicles of the face.
