    Notes: The differential diagnosis of herpes simplex and zoster may require virological confirmation, yet virus typing is not regarded as necessary in routine dermatological assessment. In an attempt to evaluate the clinical benefits of the routine detection of herpes simplex virus (HSV) and varicella zoster virus (VZV), we analysed skin swabs from 110 patients who were diagnosed at the first clinical visit as having herpes simplex (n = 45) or zoster (n = 65). Viruses were typed using the polymerase chain reaction (PCR) with the general primer pair GPHV-RU. PCR analysis showed that at the initial clinical presentation, herpes simplex in these patients was not mistaken for zoster but that zoster was incorrectly diagnosed as herpes simplex in nine cases. Thus these results suggest that initial zoster often mimics herpes simplex, hence routine PCR diagnosis of HSV and VZV or alternative rapid diagnostic approaches may be beneficial in these cases.

    Notes: We studied the papillomfiviruses (HPV) found in 131 common warts Irom 111 immunocompetent patients by amplification of viral DNA sequences with the general-primer-mediatcd polymerase chain reaction (PCR). The virus types were determined by restriction-enzyme cleavage and reverse-hlot analysis. Results were confirmed by using the Southern blot technique.Forty patients harboured HPV 2a. 25 individuals showed HPV 2c and 13 yielded HPV 57. Common warts from 16 patients were induced by a variant of HPV 57. HPV 7 was found in four patients. HPV 1 was identified in two patients, and there was evidence for HPV 4 in only one case. One individual yielded an HPV type wbich was only weakly related to HPV 2. Three patients were infected by more than one HPV type. PCR did not demonstrate HPV-DNA in warts from six individuals. The distribution and variation of HPV types found in the common warts of immunocompetent patients were similar to the findings in immunocompromised patients reported by other authors.

    Notes: Abstract The morphology of common warts depends on the inducing human papillomavirus (HPV) type. In order to assess the impact of the virus type on wart epidemiology we determined the virus type by PCR and recorded anamnestic data of 238 patients with common warts. Warts induced by the related HPV types 2, 27 and 57 predominated in the study population (n = 202). These warts mostly occurred as multiple verrucae vulgares, mosaic warts or endophytic warts. Patients aged between 10 and 30 years were most affected and they typically displayed a long disease history (mean duration of warts at the time of first clinical examination, 22 months). A different age distribution was observed in HPV 1-induced warts, most of which occurred in children 6–10 years of age. HPV 2-related warts responded only modestly to treatment, as they persisted in approximately 50% of all patients for more than 6 additional months. No sex preference was detected, but an association with atopic diseases was noted as 39.8% of patients with warts containing HPV 2-related viruses showed a history of atopic eczema, pollinosis or asthma as compared with 20.6% of the control population without a history of warts or with short-duration wart disease. Thus, our results indicate that the epidemiology, as well as morphology, of common warts is closely linked to the virus type.

    Notes: Abstract A 3-year-old boy of German descent suffered from two episodes of Streptococcus pneumoniae meningitis within 2 months. One month previously, the first skin lesion of Kaposi sarcoma (KS) had been observed behind his right ear. During the following 2 years KS disseminated not only mucocutaneously but also to visceral organs. Immunological evaluation revealed severe lymphocytopenia with reduced helper/suppressor T-cell ratio and impaired humoral immune response to pneumococci. Extensive laboratory tests gave no evidence for known immunocompromising infections. However, recently described DNA sequences from a Kaposi sarcoma-associated herpesvirus (KSHV) could be identified within skin tissue. As chemotherapy failed to stop tumour progression the patient was referred for bone marrow transplantation. Eighteen months later the KS is in remission and the patient in a good general condition. Conclusion The case supports the hypothesis that KSHV is involved in the aetiology of KS. Bone marrow transplantation is possibly a therapeutic option for KS in patients with immunodeficiency not related to human immunodeficiency virus infection.

    Description / Table of Contents: Zusammenfassung Das Riesenkondylom in anorektaler Lokalisation ist eine extreme Rarität. Obwohl der blumenkohlförmige Tumor klinisch ein malignes Wachstum zeigt, erfüllt er nicht die histomorphologischen Kriterien der Malignität. In der Literatur sind bis heute 33 Fälle eines Riesenanorektalkondyloms beschrieben worden, davon 42% mit maligner Transformation in ein Schuppenzellkarzinom. Zwei weitere Fälle eines invasiven Schuppenzellkarzinoms auf dem Boden eines Riesenzellkondyloms werden berichtet. Der Buschke-Löenstein-Tumor ist ein Zwischenstadium des “einfachen” Kondyloms und des Schuppenzellkarzinoms. Condylomata acuminata werden durch die humanen Papillomavirus-Typen 6 und 11 verursacht. Karzinogene Kofaktoren bewirken den Übergang in das Riesenkondylom mit lokal destruierendem Wachstum und folgender maligner Transformation. Nur die rechtzeitige, lokale, radikale Exzision im Gesunden verspricht therapeutischen Erfolg. Multiple Fisteln und die Zerstörung des Sphinkterapparates können die abdominoperineale Rektumamputation erforderlich machen. Eine Bestrahlung sollte nur erfolgen, um Operabilität herzustellen, da sie einen kokarzinogen Effekt auf den Tumor aufweist und eine Entdifferenzierung in ein aggressiv wachsendes Karzinom auslöst.
    Notes: Abstract Giant condyloma acuminata, first described by Buschke and Löwenstein in 1925 as a penile lesion, is extremely rare in the anorectal region. The cauliflower-like tumor behaves clinically in a malignant fashion, although it shows no histomorphological criteria of malignancy. Up to the time of writing only 33 cases of anorectal origin, 42% with malignant transformation, have been published. The authors report 2 more cases of squamous-cell carcinoma in giant anorectal condylomata acuminata. Buschke-Löwenstein tumor is an intermediate entity between “ordinary” condyloma acuminata and squamous-cell carcinoma. Benign condyloma acuminata is caused by human papillomavirus 6 or 11. Carcinogenic cofactors promote the transition to giant, locally destructive condyloma acuminata and subsequent malignant transformation. Cure can only be achieved by early and radical excision. Formation of multiple fistulas and destruction of the sphincter may necessitate abdomino-perineal resection. Adjuvant radiation therapy should only be considered to render a tumor operable, as radiation may act as a cocarcinogenic effect and lead to a less differentiated and more aggressive cancer. The small number of cases reported and the variety of treatment regimens applied, however, do not allow the formulation of definitive therapeutic guidelines.
