1/7. Prominent hyperkeratotic plantar and palmar warts.We report the case of a 28-year-old man who had prominent hyperkeratotic plantar and palmar warts, and flat warts on his face and chest. By dna hybridization, human papillomavirus 1 and/or 2, and 3 dna were detected from the tissues of these skin lesions. Results of laboratory investigations revealed leukopenia, eosinophilia, anti-HBs antigen and anti-hepatitis c virus antibody, and decrease in the OKT4/OKT8 ratio. He had no abnormality in cellular immunity. He was treated with multiple modalities, but was successfully treated with electrocautery to the plantar and palmar warts, and cryotherapy with liquid nitrogen to the flat warts. Nine years after the initial treatment, almost no recurrence was recognized.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
2/7. Epstein-Barr virus-associated lymphoproliferative skin lesion with recurrent necrotic papulovesicles of the face.A 24-year-old man showed recurrent necrotic papulovesicles of the face. The cutaneous lesions started with erythema, followed by vesicles, necrosis, and crusting, and leaving depressed scars. light avoidance did not prevent the development of the lesions. Histologic examination revealed lymphoproliferative lesions confined to the skin. Latent Epstein-Barr virus (EBV) infection was detected in the lymphoid cells from the skin lesions by in situ hybridization. A moderate to high dosage of corticosteroids suppressed the development of new skin lesions, but relapses occurred when these systemic corticosteroids were tapered.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
3/7. Epstein-Barr virus-associated peripheral T-cell lymphoma in adults with hydroa vacciniforme-like lesions.We describe two Korean adult patients who had necrotizing papulovesicles mainly on their faces. Skin biopsy specimens showed perivascular and periadnexal infiltrate of atypical lymphoid cells with vasculitis in the dermis and subcutaneous tissue. in situ hybridization demonstrated a latent infection of Epstein-Barr virus in the majority of lymphoid cells in the dermis. These patients were diagnosed as having T-cell lymphoma. Interestingly, large granular lymphocytosis was found in the peripheral blood of Case 2.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
4/7. hydroa vacciniforme-like eruptions in a patient with chronic active EB virus infection.We report a case of chronic active Epstein-Barr (EB) virus infection (CAEBV) associated with skin eruptions mimicking hydroa vacciniforme (HV) in a 4-year-old boy. The patient had repeated episodes of vesiculo-necrotic eruptions on the face, scalp, and bilateral forearms one year before the first visit to our department. General symptoms including fever, hepatosplenomegaly, abnormal liver function, and cervical lymph node swelling were noted three months before the first visit. At the first visit, small, bean-sized, erythemic papules with central necrosis were observed on the face and anterior chest wall. thumb-sized ulcers with crust were present on the bilateral forearms. Histopathological examination of an erythematous lesion in the submandibular area revealed parakeratosis with a thick crust, mild spongiosis in the epidermis, and a dense infiltration of lymphoid cells into the dermis and perivascular space. Laboratory examination showed EBNA x 40, EBV VCA IgG x 1,280, and EBV dna (PCR) 8 x 10(4). EBV-encoded small nuclear rna (EBER) positive cells were detected in the dermis by an in situ hybridization (ISH) method. Large granular lymphocytes (65%) with the NK cell phenotype were found in the peripheral blood. A real time PCR method showed 171,741 copies/ micro g dna in CD 16 positive cells. Although latent EBV infection-associated eruptions have been documented, detailed skin manifestations in CAEBV are less well known.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
5/7. 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.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
6/7. Multiple inverted follicular keratoses as a presenting sign of Cowden's syndrome: case report with human papillomavirus studies.Inverted follicular keratosis is characterized by a squamous epithelial expansion of the infundibular portion of the hair follicle in an exophytic and endophytic pattern. The lesion is often associated with squamous eddies similar to an irritated keratosis and may have a superficial papillomatous architecture. The lesion most often arises as a solitary nodule on the face of middle age to elderly individuals. Inverted follicular keratosis has been described as a distinct entity by some while others believe that it is related to trichilemmomas and/or verruca vulgares. The cutaneous pathology of Cowden's syndrome is characterized by multiple trichilemmomas. We present a woman who fulfills the clinical criteria for Cowden's syndrome and who initially presented with multiple inverted follicular keratoses. Also, in situ hybridization studies performed on the patient's keratoses do not reveal evidence of human papillomavirus infection.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
7/7. An Epstein-Barr virus-associated lymphoproliferative lesion of the skin presenting as recurrent necrotic papulovesicles of the face.We describe four patients with lymphoproliferative lesions confined to the skin for several years. They presented with recurrent necrotic papulovesicles of the face. Latent Epstein-Barr virus (EBV) infection was detected in the lymphoid cells from the skin lesions by in situ hybridization. The disease in three patients progressed to T-cell lymphoma. We believe that these patients represent a subset of peripheral T-cell lymphoma with a tendency to localize in the skin.- - - - - - - - - - ranking = 1keywords = hybridization (Clic here for more details about this article) |
