Herpes simplex associated with Hailey-Hailey disease

Hailey-Hailey Disease With Coexistent Herpes Virus Infection: Insights Into the Diagnostic Conundrum of Herpetic/Pseudoherpetic Features in Cutaneous Acantholytic Disorders

The specific histopathologic diagnosis of a primary acantholytic disorder takes into account the distribution and extent of acantholysis, presence or absence of dyskeratosis, nature of the dermal inflammatory cell infiltrate, and immunofluorescence findings. Herpes virus infection is a common cause of secondary acantholysis where distinctive viral cytopathic changes aid in making it a clear-cut diagnosis in majority of cases. We present a case of coexistence of Hailey-Hailey disease and herpes simplex virus infection to compare and contrast their histopathologic features. This is imperative because acantholytic cells from primary acantholytic disorders may occasionally show cytological features traditionally associated with herpes virus infection (pseudoherpetic changes). The objective of this article is to create a greater awareness of pseudoherpetic changes and also to explore the clinical significance of coexistence of a primary acantholytic disorder and herpes virus infection, as in this case.

A case of eczema herpeticum with hailey-hailey disease

Eczema herpeticum is the dissemination of herpes simplex virus in the setting of a preexisting skin disease. Hailey-Hailey disease [familial benign chronic pemphigus] is a blistering dermatosis that is inherited as an autosomal dominant trait and it usually presents itself around the third or fourth decades. Coexistence of eczema herpeticum and Hailey-Hailey disease is an infrequent occurrence. Four such cases have been reported in the English and German medical literature. We report here on an unusual case of eczema herpeticum that coexisted with Hailey-Hailey disease in a 47 years old man and we review the relevant literatures.

Occult herpes simplex virus colonization of bullous dermatitides

BACKGROUND

Acantholytic disorders, including pemphigus vulgaris, chronic benign familial pemphigus (Hailey-Hailey disease, superficial pemphigus), Darier disease, and Grover transient acantholytic dermatosis, as well as other vesiculo-bullous disorders, including bullous pemphigoid, epidermolysis bullosa, and atopic dermatitis, are prone to florid infections by herpes simplex virus (HSV)-I and -II, and, more rarely, by varicella-zoster virus (VZV). As these infections are difficult to recognize clinically and histologically, their frequency remains unknown. A possible occult viral colonization has never been documented in these disorders. The manner in which the primary bullous disorders are contaminated by herpesviridae remains unclear.

OBJECTIVE

To retrospectively assess the possible presence of HSV and VZV in a series of biopsies of acantholytic disorders and bullous pemphigoid.

METHOD

The typical alpha-herpesviridae-related cytopathic signs were searched for by conventional microscopy in skin biopsies of patients with bullous pemphigoid (n = 20), pemphigus vulgaris (n = 19), Darier disease (n = 18), chronic benign familial pemphigus (n = 3), and Grover transient acantholytic dermatosis (n = 3). Immunohistochemistry (IHC) targeted specific HSV-I, HSV-II, and VZV antigens. Polymerase chain reaction (PCR) was used for detecting HSV- and VZV-specific DNA sequences.

RESULTS

No cytopathic signs suggestive of HSV or VZV infection were detected. However, IHC revealed HSV antigens in Darier disease (1/18, HSV-I), Grover transient acantholytic dermatosis (1/3, HSV-I), pemphigus vulgaris (1/19, HSV-I), and bullous pemphigoid (2/20, HSV-I and HSV-II). In these IHC-positive cases, PCR amplified specific HSV primers in Darier disease (1/18), pemphigus vulgaris (1/19), and bullous pemphigoid (1/20). VZV antigens and nucleic acids were never identified. The HSV antigens were nearly always restricted to the upper part of the granular layer and thus differed from the usual HSV distribution during cutaneous infection. Negative and positive controls yielded consistently positive and negative results, respectively.

CONCLUSION

This report shows for the first time that clinically and histologically occult HSV colonization may occur in Darier disease, Grover transient acantholytic disease, pemphigus vulgaris, and bullous pemphigoid. Given the frequent use of immunosuppressive treatments for primary bullous disorders, greater awareness of HSV colonization and infection is recommended in these patients.

Acute generalized Hailey-Hailey disease

A patient with extensive histologically proven Hailey-Hailey disease is described whose initial clinical presentation was suggestive of erythema multiforme or toxic epidermal necrolysis. This potentially misleading morphology of acute proven Hailey-Hailey disease has not been described previously and may be a consequence of bacterial infection exacerbating acantholysis.

Human papillomavirus types 16 and 39 in a vulval carcinoma occurring in a woman with Hailey-Hailey disease

A woman with Hailey-Hailey disease, suffering from carcinoma of the vulva, was examined by histology and for the presence of human papillomavirus (HPV) DNA by polymerase chain reaction (PCR) and in situ hybridization. Our diagnosis by histological examination revealed the vulval carcinoma to be a squamous cell carcinoma (SCC), adjacent to lesions of Hailey-Hailey disease and severe dysplasia/carcinoma in situ [vulval intraepithelial neoplasia (VIN) III]. The PCR with consensus primers for the L1 region (L1-PCR) successfully amplified HPV DNA using total DNA extracted from formalin-fixed and paraffin-embedded tissue specimens. Restriction fragment length polymorphism analysis and sequencing of L1-PCR products revealed HPV types 16 and 39. HPV 16-specific primers for the E6 region identified HPV 16 DNA. In situ hybridization analysis with biotinylated HPV 16 and 39 DNA probes revealed the presence of the HPV 39 genome in the nuclei of the tumour cells in the SCC. These results indicate that HPV 16 and 39 are associated with lesions in vulval carcinoma. Regarding the patient's susceptibility to infection in the case of Hailey-Hailey disease, there is a possibility that HPV was inoculated into the lesions of Hailey-Hailey disease and induced those of VIN III and SCC.

Hailey-Hailey disease: the clinical features, response to treatment and prognosis

Fifty-eight individuals with Hailey-Hailey disease were studied to delineate the clinical features, response to treatment and prognosis. The disease generally presented between the second and fourth decades, but the morphology of lesions was varied and a delay in diagnosis was common. Nail changes have not been documented in previous studies of Hailey-Hailey disease, but asymptomatic longitudinal white bands were present in the fingernails in 71% of 38 patients examined and are a helpful physical sign. The disease is predominantly flexural. Friction and heat or sweating exacerbate the lesions and pain may limit physical activities. The prognosis was assessed in 27 patients with longstanding disease and the long-term outlook is generally good. Seventeen patients had improved and the disease was static in seven patients. Three patients deteriorated with age. Topical corticosteroids with or without added antibiotics were an effective treatment.
