Paronychia: a sign heralding an exacerbation of pemphigus vulgaris

Nail Involvement during Pemphigus

BACKGROUND

Pemphigus is an autoimmune bullous disease affecting the skin and mucous membranes. Associated nail involvement is underestimated and is characterized by a variety of clinical manifestations. Our aim was to describe the clinical aspects of nail involvement during pemphigus.

PATIENTS AND METHODS

A retrospective study was conducted of patients with pemphigus over a period of 12 years. The diagnosis of pemphigus was based on clinical and immunopathological data. Clinical data were collected from patient records prior to initiation of treatment.

RESULTS

Overall,141 cases of pemphigus were collected. Of these, 60 patients had nail involvement. After eliminating fungal origin, we selected 37 patients in our study. The main clinical forms were paronychia and dystrophy. Two cases of destruction of the nail apparatus were found in patients with pemphigus vegetans. The disease was bilateral in 11 cases (29.7%). The presence of ungual involvement was correlated with severity of pemphigus, particularly severe oral disease (p = 0.002).

CONCLUSION

Nail lesions were polymorphic in our patients. These signs show accumulated inflammation of the nail after a long evolution of the disease. Nail involvement may precede, be concomitant, or follow the mucocutaneous lesions of pemphigus and be a sign of severity or relapse of the disease.

Nail changes in autoimmune blistering disorders: A case-control study

Background

Pemphigus and pemphigoid disorders produce blistering cutaneous lesions. Earlier case reports state that nail involvement is uncommon in these autoimmune blistering disorders.

Aims and Objectives

To study nail changes in autoimmune blistering disorders.

Methods

A case-control study was conducted where 40 cases and 40 controls were evaluated for nail changes.

Results

Nail changes were seen in 72.5% of cases and 17.5% of controls. The most common nail findings were paronychia and onychorrhexis.

Limitations

Small sample size; short study duration; nail biopsy could not be done.

Conclusion

Our findings indicate that the inflammatory nature of the blistering cutaneous disease is often reflected conspicuously in the nails.

Involvement of Nail Apparatus in Pemphigus Vulgaris in Ethnic Poles Is Infrequent

Pemphigus vulgaris lesions have a tendency to localize around natural body orifices. The aim here was to analyze the involvement of nail apparatus in pemphigus vulgaris. Sixty seven ethnic Poles suffering from pemphigus vulgaris on photographic files archiving initial presentation were retrospectively evaluated. Pemphigus vulgaris was diagnosed using combination of clinical data, H+E histology, direct immunofluorescence of plucked scalp hair and/or perilesional tissue also for IgG1 and IgG4 deposits evaluation, indirect immunofluorescence on mosaic substrate and/or monkey esophagus, mono-analyte ELISA with desmoglein 1/3 or multi-analyte ELISA. The nail apparatus involvement was found in 9 of 67 patients (13.4%; 3 females and 6 males). Periungual fingernail lesions were found in 6 patients (2 females, 4 males), whereas periungual toenail lesions in just 3 patients (1 female, 2 males). Our patients nail apparatus changes included, by order of frequency, paronychia, nail discoloration, onychorrhexis, Beau lines, periungual hemorrhages, onychomadesis, cross-ridging, onycholysis, and trachyonychia. The average time between the onset, as recalled by patients, and the diagnosis of pemphigus vulgaris with direct immunofluorescence was not statistically different in PV patients with and without nail apparatus lesions. In this article the molecular and immunological rationale for of periungual involvement is discussed. Our single-center study suggests that nail apparatus involvement is infrequent in pemphigus vulgaris in ethnic Poles. Due to the fact that nail apparatus lesions in pemphigus vulgaris may clinically resemble onychomycosis, giving the proper diagnosis can be difficult particularly when other lesions are overlooked or misinterpreted.

Recurrent Paronychia as a Presenting Manifestation of Pemphigus Vulgaris: A Case Report

Nail involvement in pemphigus vulgaris (PV) is an unusual clinical finding. The most common clinical manifestations include chronic paronychia and onychomadesis. We report an adult female patient with PV who initially presented with chronic paronychia of multiple fingernails and toenails before the onset of vesiculobullous eruptions. Later on, after complete resolution, there was recurrence of pemphigus presenting as hemorrhagic paronychia of the left index finger. Systemic treatment with corticosteroids and azathioprine led to complete resolution of mucocutaneous lesions as well as nail manifestations. Thus, chronic treatment-resistant paronychia may be an early and important sign of generalized pemphigus in certain patients.

Acute paronychia heralding the exacerbation of pemphigus vulgaris

Acute paronychia, the suppurative inflammation involving the paronychium of the nails, is usually caused by bacterial or fungal infection and has been rarely reported as a presentation of pemphigus vulgaris (PV). We report a woman with PV who presented with suppurative paronychia of multiple fingernails and toenails, which preceded the exacerbation of other mucocutaneous lesions. A biopsy specimen of the paronychium revealed suprabasal vesicles due to acantholysis. Systemic corticosteroids and adjuvant immunosuppressants were effective in treating mucocutaneous lesions as well as nail disease. We conclude that in patients with PV, acute paronychia could be a manifestation of the disease per se, rather than an infectious process. Only the precise diagnosis with adequate immunosuppressive treatment can lead to good control of disease activity.

Nail manifestations in pemphigus vulgaris

Nail involvement in pemphigus vulgaris is rare. We describe 5 patients with pemphigus vulgaris presenting nail involvement. In this disease, nail manifestations present, by order of frequency, as chronic paronychia, onychomadesis, onycholysis, Beau's lines and trachyonychia. All our 5 cases presented with paronychia, and 1 of them also had Beau's lines. Treatment with prednisone and/or cyclophosphamide controlled mucocutaneous and nail manifestations in all cases.

Nail involvement in pemphigus vulgaris

BACKGROUND

Involvement of the nail unit in pemphigus vulgaris (PV) is thought to be rare.

OBJECTIVES

To determine the frequency of nail changes among patients with PV.

METHODS

Nail changes were recorded in patients with PV and were analysed retrospectively. Biopsies were taken from the nail bed and nail matrix for histological and immunofluorescence observations. Microscopic (potassium hydroxide) examination and fungal culture were performed.

RESULTS

Nail changes were present in 30 of 64 (47%) patients with PV. Sixteen patients had onychomycosis and 14 had nail changes due to PV. These included onychomadesis, discoloration, deformity, onychorrhexis, onycholysis, subungual haemorrhage, subungual hyperkeratosis and paronychia. Onychomycosis affected fingernails and toenails, but changes due to PV occurred only in fingernails, most commonly on the thumb and index finger. No connection was found between the patient's occupation and nail involvement, and there was no correlation with the severity or duration of PV. In a control group of 64 patients of similar sex and age, only two had non-specific fingernail changes.

CONCLUSIONS

Nail changes in PV may be more frequent than previously thought.

Nail involvement in pemphigus vulgaris

Nail involvement in pemphigus vulgaris is relatively rare. We describe a case of severe pemphigus involving both the skin and oral mucosa in which an acute exacerbation was preceded by the onset of nail involvement of all 4 extremities. Nail involvement occurred in the form of hemorrhagic paronychia of multiple digits. Oral, cutaneous, and nail manifestations of the disease were all well controlled by systemic therapy. A review of the literature on nail involvement in pemphigus reveals that this involvement may be manifested in multiple ways, with chronic paronychia and onychomadesis being the most common. Involvement of the nail occurs most frequently either as part of the initial presentation, or just before or concurrent with a flare of pre-existing disease. Nail involvement, when it occurs, is usually present when the disease is severe. Topical therapy is insufficient, and systemic therapy is warranted. In the majority of cases, nail recovery is complete, with no residual damage.

Paronychia--a manifestation of pemphigus vulgaris

Involvement of the nail unit in pemphigus vulgaris is thought to be uncommon. However, trachyonychia, nail atrophy, onychomadesis, onycholysis, nail bed erosion, onychoschizia, subungual haemorrhage, nail pitting, nail plate discoloration, cross-ridging of nail plate, Beau's line and paronychia have been reported. These manifestations may be due either to secondary extension of the bulla adjacent to the nail or primary involvement of the nail bed, nail matrix and nail fold. We report four patients with pemphigus vulgaris who developed paronychia with a corresponding exacerbation of their cutaneous lesions. Nail fold biopsy and direct immunofluorescence revealed features of permphigus vulgaris. Treatment with immunosuppressive agents showed simultaneous improvement of both cutaneous and nail lesions.
