Lymphocoele and localized lymphoedema of the penis. (1/177)

Six patients with lymphocoele or sclerosing lymphangitis of the penis attended the Department of Venereology, Royal Infirmary, Edinburgh, during a 9-month period. Clinical details of these patients are given and the aetiology of the condition is discussed.  (+info)

Tissue specific HPV expression and downregulation of local immune responses in condylomas from HIV seropositive individuals. (2/177)

OBJECTIVE: To study the effect of tissue specific human papillomavirus (HPV) expression and its effect on local immunity in condylomas from HIV positive individuals. METHODS: Biopsy specimens of eight penile and eight perianal condylomas from HIV seropositive individuals were analysed. Expression of viral genes (HIV-tat and HPV E7 and L1) was determined by RT-PCR. The status of local immunity also was determined by RT-PCR by measuring CD4, CD8, CD16, CD1a, HLA-DR, and HLA-B7 mRNA levels in the tissues. Differentiation was determined by measuring involucrin, keratinocyte transglutaminase, as well as cytokeratins 10, 16, and 17. Proliferation markers such as PCNA and c-myc were also determined. RESULTS: The transcription pattern of HPV in perianal condylomas, which preferentially expressed the early (E7) gene, was different from that of penile condylomas, which primarily expressed the late (L1) gene. This transcription pattern is in good correlation with the keratinisation and differentiation patterns of the two epithelia: perianal biopsies preferentially expressed K16 and K17 while penile warts mainly expressed K10, markers of parakeratotic and orthokeratotic epithelia, respectively. Perianal biopsies also showed a higher degree of proliferation (PCNA and c-myc). Interestingly, transcription of HIV-tat was also higher in perianal than in penile biopsies. A high degree of local immunodeficiency was observed in perianal biopsies--that is, levels of CD4, CD16, and CD1a mRNAs were significantly lower. A negative correlation between CD1a (Langerhans cells) levels and HPV E7 levels was established. HPV E7 levels positively correlated with HIV-tat levels. Perianal tissues demonstrated more CD1a depression and tat associated HPV upregulation. CONCLUSION: HIV influences the expression of HPV genes resulting in local immunosuppression that might lead to an inappropriate immune surveillance of viral infection. Also, tissue type is an important factor in controlling viral transcription in a differentiation dependent manner. These findings may explain the higher rate of dysplasia and neoplasia in the perianal area.  (+info)

Penile granuloma annulare. (3/177)

A case of granuloma annulare (GA) localised to the shaft of the penis is reported with a brief review of the current literature. We concluded that penile GA, although rare, should be considered in the differential diagnosis of granulomatous lesions of the penis and that histopathological examination of the lesion is essential for the diagnosis.  (+info)

Dorsal perforation of prepuce: a common end point of severe ulcerative genital diseases? (4/177)

Severe ulcerative genital diseases can cause destruction of the prepuce, glans, or sometimes of the whole penis (phagedena). We observed a characteristic pattern of partial destruction of the prepuce as a result of a wide variety of ulcerative genital diseases. Five patients, two with severe genital herpes, one with hidradenitis suppurativa, and two with donovanosis presented with perforation on the dorsal surface of the prepuce. In four of them, the glans protruded through the defect and in one, the defect was not large enough to allow protrusion of the glans. In two patients, the preputial sac was obliterated. The relatively decreased blood supply of the prepuce is the probable explanation for perforation at this selective site.  (+info)

Pyogenic granuloma of the penis--don't squeeze them. (5/177)

We report the case of a pyogenic granuloma on the shaft of the penis presenting with active bleeding secondary to attempted expression. Previously reported cases have documented such lesions on the prepuce and glans.  (+info)

Penile resurfacing for extensive genital warts. (6/177)

Complete surgical excision followed by reconstruction, of diseased penile skin may result in sexual dysfunction due to tethering of the underlying Buck's fascia by the graft. We describe penile resurfacing for extensive condyloma accuminata, a novel technique that circumvents this complication without compromising clearance of this particular lesion.  (+info)

Circumcision: a refined technique and 5 year review. (7/177)

The vast majority of circumcisions currently performed in the UK are for phimosis or balanitis and the patients are not looking for the denuded glans appearance of a ritual circumcision. We present a refinement of the sleeve technique of circumcision, which involves Horton's test to define the proximal incision margin, and bipolar electro-dissection. A review of all patients undergoing circumcision at the Wordsley Plastic Surgery Unit, in a 5-year period, has shown this technique to be safe with a haematoma rate of only 1.4%, and an overall complication rate of 3%.  (+info)

Penile Mondor's disease in a 22-year-old man. (8/177)

Penile Mondor's disease (superficial thrombophlebitis of the dorsal vein of the penis) is an important clinical diagnosis that every family practitioner should be able to recognize. Although penile Mondor's disease is rare, proper diagnosis and consequent reassurance can help to dissipate the anxiety typically experienced by patients with the disease. This article describes the symptomatology, diagnosis, and treatment of superficial thrombophlebitis of the dorsal vein of the penis.  (+info)
