Objective The purpose of this study was to show the benefits and limitations of vulvar biopsy in the setting of a multidisciplinary clinic specialising in non‐neoplastic diseases of the vagina and vulva. Design One hundred and fourteen vulvar biopsies were reviewed and classified according to the classification of the International Society for the Study of Vulvar Diseases. Results The histological diagnoses were lichen sclerosus 25 YO, nonlichen simplex chronicus 35%, erosive inflammatory dermatoses comprising psoriasis, spongiotic dermatitis, dermatophytosis and psoriasiform dermatitis 13%, erosive vulvitis and lichen planus 9%, nonspecific inflammation 6%, miscellaneous 9% and normal 4%. Conclusions Biopsies in cases of lichen sclerosus were useful for confirmation of clinical diagnosis and to exclude early invasive malignancy. In lichen simplex chronicus, biopsies helped exclude an underlying dermatosis requiring specific treatment. Psoriasis, spongiotic dermatitis, dermatophytosis and excoriated lichen simplex chronicus posed a common clinical differential diagnosis of the reddened vulva. The eroded vulva often proved a diagnostic problem clinically and histologically. The clinical syndrome of vestibulitis did not have a specific histological picture, and biopsies showed nonspecific inflammation, mild hyperplasia or were normal. No case of squamous cell hyperplasia was diagnosed and the place of this diagnosis in the ISSVD classification needs review.

A 65-year-old man presented with a widespread erythematous maculopapular eruption. Skin biopsy showed spongiosis and focal acantholytic dyskeratosis consistent with Grover's disease. Clinically the eruption evolved to erythroderma with typical features of pityriasis rubra pilaris. On review of the histology, changes consistent with this diagnosis were also present in addition to the acantholytic dyskeratosis.

Objective To determine whether human papillomavirus (HPV) was responsible for symptoms in women with vulvar pruritus, pain and superficial dyspareunia who had been referred with a diagnosis of HPV vulvar disease made on clinical and/or colposcopic and/or histological grounds. Design In addition to standard clinical and laboratory investigations of the whole population, a sample of 15 test cases from the population of 71 women referred with a clinicopathological diagnosis of HPV vulvar disease, and two positive and 21 negative controls were assayed for HPV DNA. Polymerase chain reaction assays using L1 consensus primers were performed blinded to the clinicopathological diagnosis. Setting Dermogynaecology Clinic at Mercy Hospital for Women. Subjects Seventy‐one women referred with a diagnosis of HPV vulvar disease. Results Thirteen cases which could be tested for HPV DNA were negative. Diagnoses other than HPV were found for the women's presentation in all cases. Conclusions In the population studied, our investigations indicated that the clinicopathological diagnosis of HPV infection was incorrect and that HPV was not a cause of vulvar symptoms. We believe that the term HPV vulvitis is unfortunate as it has invited destructive treatments and drawn attention away from more likely causes of this difficult group of vulvar conditions.

A case of congenital hydrocephalus in a male infant with flexion deformity of the thumbs and great toes is reported. A maternal uncle had undefined intellectual impairment and X-linked hydrocephalus was considered among the differential diagnoses. However, this diagnosis was considered unlikely as the pyramids were preserved at autopsy. In addition, postmortem histopathology and viral culture established cytomegalovirus (CMV) infection as the underlying cause of the hydrocephalus. Although CMV infection is a well recognized cause of congenital hydrocephalus, the associated flexion deformities of the thumbs and great toes have not been previously described and may reflect injury to the corticospinal tracts.

Haemophagocytic lymphohistiocytosis complicating Epstein-Barr virus positive T-cell lymphoproliferative disease of childhood is a rare and life-threatening entity. We report a child with this condition presenting with a toxic epidermal necrolysis-like eruption.

The contributions of direct immunofluorescence, light microscopy and serology to the investigation of 52 patients with possible lupus erythematosus were studied. Direct immunofluorescence was found to be most valuable in the investigation of possible systemic lupus erythematosus whilst only of supportive value in the investigation of possible chronic discoid lupus erythematosus. The importance of performing light microscopy before direct immunofluorescence in cases of possible chronic discoid lupus erythematosus is shown.
