1/2. pemphigus vulgaris localized to the vagina presenting as chronic vaginal discharge.Involvement in pemphigus vulgaris of the female genital tract including the vulva, vagina and cervix has previously been described. In all these cases other cutaneous and mucosal sites have also been affected at some time. We describe a case of pemphigus vulgaris which only involved the vaginal mucosa. The patient presented with a persistent vaginal discharge and examination showed extensive vaginal erosions. histology of vaginal biopsies was non-diagnostic. The recognition that the vaginal changes may represent an immunobullous disease led to further vaginal biopsies on which direct immunofluorescence studies were performed. These biopsies showed IgG and C3 in the intercellular epidermis, suggesting a diagnosis of pemphigus vulgaris. During the 3-year period that the patient has been under review there have never been any other cutaneous or mucosal lesions. To our knowledge, this is the first case of pemphigus vulgaris localized exclusively to the vaginal mucosa. There was considerable delay in diagnosis and this case highlights how important it is to recognize that chronic mucosal lesions at genital sites may be caused by immunobullous diseases such as cicatricial pemphigoid and pemphigus, and to institute appropriate investigations.- - - - - - - - - - ranking = 1keywords = vulgaris (Clic here for more details about this article) |
2/2. Acantholytic cells exfoliated from pemphigus vulgaris of the uterine cervix. A case report.BACKGROUND: pemphigus vulgaris of the uterine cervix is rare and almost always associated with cutaneous or mucosal lesions elsewhere on the body. Without a history of pemphigus, acantholytic cells in cervical smears may be misdiagnosed as malignant ones. CASE: A 52-year-old female presented with a vaginal discharge, and a routine cervical smear was collected for cytology. The smear displayed atypical cells lying singly and in loose clusters, having vesicular nuclei, a thin nuclear membrane, prominent nucleoli and well-defined cytoplasmic margins. These were labeled atypical glandular cells of undetermined significance, and colposcopic examination and biopsy were advised. On colposcopy vesicular lesions and erosions were noticed on the cervix. The biopsy revealed typical intact as well as denuded suprabasal bullae of pemphigus vulgaris. On reevaluation of the cytologic smear, the cytomorphologic features correlated well with the acantholytic cells of pemphigus. Thorough reexamination of the patient revealed 2 tiny vesicles on the oral mucosa that, on biopsy, confirmed the diagnosis of pemphigus vulgaris. CONCLUSION: Cytopathologists should be aware of the typical cytomorphologic features of pemphigus vulgaris and, in an appropriate clinical setting, should be able to diagnose or at least suspect this entity in even rare sites like the cervix. A false positive diagnosis of malignancy can be avoided if the cytologic findings are judiciously correlated with the history and with clinical and colposcopic examinations.- - - - - - - - - - ranking = 1keywords = vulgaris (Clic here for more details about this article) |
