Pemphigus vulgaris is an autoimmune bullous dermatosis presenting with flaccid blisters and erosions. The morphology of pemphigus reflects the more superficial intraepidermal level of split seen histologically in contrast with pemphigoid, where the level of split is deep below the epidermis. This is a case of a 58-year-old male clinically presenting with arcuate tense bullae, which are more characteristic of the pemphigoid group of disorders, which revealed an intraepidermal split and tombstoning pattern of the basal epidermis on histopathology. Direct immunofluorescence revealed intercellular IgG and C3 distribution. Although this patient presented clinically with tense bullae, the histopathology and direct immunofluorescence results were consistent with pemphigus vulgaris.

Hailey-Hailey disease (HHD) is an uncommon acantholytic disorder of the skin. This is a case of a 64-year-old Filipino female with a chronic history of painful and malodorous intertriginous plaques. Histopathologic evaluation showed overlapping features of pemphigus vulgaris and Hailey-Hailey disease. A negative direct immunofluorescence test clinched the diagnosis of Hailey-Hailey disease. The patient was advised regarding preventive measures and treated with topical antibiotics and corticosteroids with improvement of her lesions.

Pemphigus foliaceous is a rare autoimmune blistering disease, while psoriasis is a common immune‑mediated
inflammatory skin disease. The coexistence of psoriasis and pemphigus foliaceous has rarely been
reported. We report a case of a 55‑year‑old Filipino female with an 8‑year history of chronic plaque‑type
psoriasis biopsy‑proven. After 5 years, she developed generalized flaccid bullae and crusted erosions
over the face, trunk, and extremities, with no mucous membrane involvement. Skin punch biopsy, direct
immunofluorescence, and enzyme‑linked immunosorbent assay were consistent with pemphigus foliaceous.
The combination of topical corticosteroids and oral methotrexate was selected as the therapeutic approach,
leading to a notable improvement in the patient’s condition. This case report underscores the significance
of identifying the simultaneous presence of psoriasis alongside autoimmune blistering diseases like
pemphigus foliaceous. Examining predisposing and triggering factors, performing re‑biopsy, and further
work‑up as the disease evolves may yield more profound insights. Nonetheless, effectively managing this
condition poses a significant challenge.

Desquamative gingivitis is characterized by a diffuse erythema of the free and attached gingiva associated with areas of vesiculation, erosion, and desquamation. Desquamative gingivitis is not a distinct disease entity but represents a reaction pattern of the gingiva to various stimuli. Pemphigus vulgaris, cicatricial pemphigoid, and lichen planus may presents as desquamative gingivitis. We observed 3 patients whose disease was limited to the gingiva, and studied them by light and direct immunofluorescence microscope. We classified them according to clinical, histologic, and immunopathologic observations. Identification of the underlying causes of desquamative gingivitis is of utmost importance and is dependent upon clinical, histologic, and immunologic criteria.

We present a case of pemphigus vulgaris developed during pregnancy. The clinical features of this patient were similar to those of hetpes gestationis. By immunofluorescence studies we found that the patient's serum contained autoantibodies to intercellular substance of epidermis. Direct immunofluorescence microscopy of a perilesional skin also demontrated immunoglobulin deposition in the intercellular areas. Additionally we did in vitro C3 staining for further confirmation of the diagnosis but it was negative in basement membrane zone. This patient was initially treated with corticosteroid and azathioprine. Several months later gold compound was given instead of azathioprine and corticosteroid with good therapeutic response.

BACKGROUND: The diagnosis of bullous pemphigoid is made based on clinical, histologic, and immunofluorescence features. OBJECTIVE: The purpose of this study was to analyze the factors that may affect the positivity and intensity of direct immunofluorescence (DIF) in patients with bullous pemphigoid. METHODS: We performed a retrospective review of 41 cases of bullous pemphigoid at Ilsan Paik Hospital between January 2008 and December 2014. We investigated the positivity of DIF, immunofluorescence intensity of C3, age, sex, biopsy sites, extent of disease, duration of disease, and the degree of inflammatory cell infiltration. RESULTS: Twenty-seven of 41 (65.9%) cases had positive DIF results for either IgG or C3, and 14 of 41 (34.1%) had negative DIF results for both IgG and C3. Twenty-one cases (51.2%) of IgG and 25 cases (61.0%) of C3 had characteristic linear C3 deposition on the dermo-epidermal junction. Disease duration influenced DIF positivity (p<0.05). Although a higher positive rate of DIF was observed in biopsy specimens taken from the upper extremities than in those from other sites, the difference was not statistically significant. Sex, age, extent of disease, and the degree of inflammatory cell infiltration were not significantly associated with the positivity of DIF. There was no relationship between fluorescence intensity of C3 and the degree of inflammatory cell infiltration. CONCLUSION: This study suggests that the long duration of disease (more than 10 days) may increase the positivity of DIF. Age, sex, biopsy site, extent of disease, and the degree of inflammatory cell infiltration had no influence on DIF positivity.

Lichen planus(LP) and lupus erythematosus(LE) may occur infrequently as an overlap syndrome. The term comprises a heterogenous group of patients who have clinical, histological and/or immunopathological characteristics of both diseases at the same time. We report a case of LP/LE overlap syndrome in a 42-year-old man who has had a red to violet colored patch with atrophy and telangiectasia on the left arm for 2 years. The biopsy of the left arm showed histological features consistent with LP and LE at the same lesion. Direct immunofluorescence also showed features consistent with LP and LE at the same lesion.

BACKGROUND: Cell culture is the golden standard method for Herpes simplex virus (HSV) isolation. However, some specimens require many days to develop any cytopathic effect (CPE). We developeda rapid sensitive culture technique for HSV isolations. METHODS: This study included a total of 133 patients with suspected HSV infection. Specimens were centrifuged onto a Vero cell monolayer in a shell vial. The CPE was observed daily during the5-day incubation by inverted-phase microscope. The direct immunofluorescence (DIF) stain with aHSV specific antibody was performed 2 days after sample inoculation. The negative samples in theDIF stain were reinoculated in the new shell vials after extraction of the monolayer. Polymerase chainreaction for HSV detection was performed using the original samples. RESULTS: The CPE was observed 30 (64%), 39 (83%), 43 (92%), 44 (94%), and 46 (98%) cases at1, 2, 3, 4, and 5 days incubation, respectively. The DIF stain detected 46 cases (98%) at 2 days incubation. The CPE was observed in another 7 cases at 1-day incubation after the reinoculation of negative samples. The PCR detected 47 (100%) of 133 cases. CONCLUSIONS: The reinoculation of negative sample in a shell vial culture is a rapid sensitive methodfor HSV isolation.

A 52-year-old man had a twenty-five year history of recurrent bullous eruption that was localized to both cheeks. The diagnosis of epidermolysis bullosa acquisita was confirmed by means of direct immunofluorescence and salt-split direct immunofluorescence studies that were performed on the perilesional skin. The patient has been in partial remission state with the treatment of low dose dapsone (12.5~25 mg) and topical tacrolimus. Herein, we report on a case of EBA localized to the face, and it showed a favorable response to treatment with low-dose dapsone and topical tacrolimus.

BACKGROUND: Total T lymphocytes can be measured by CD3-fluorescein isothiocyanate (FITC)/CD4-phycoerythrin (PE) and CD3-FITC/CD8-PE. The difference in the CD3 percentages between these two determinations was evaluated. And, we characterized the CD3(+)CD4(-)CD8(-) T lymphocytes subset using the monoclonal antibody that detects gamma delta T lymphocytes receptors. METHODS: The T lymphocyte subset assay was performed on 221 samples. A two-color direct immunofluorescence flow cytometric assay was done using a Simultest IMK-Lymphocyte kit (Bec-ton- Dickinson, San Jose, CA, USA). If the difference between the CD3 determinations were greater than 3%, the entire procedure was reviewed and the flow cytograms were reanalyzed. In 71 among 221 samples the proportion of gamma delta T lymphocytes was determined. RESULTS: The difference between the CD3-FITC/CD4-PE tube and CD3-FITC/CD8-PE tube was 3.0%, 3.6%, 3.0%, 3.4%, and 2.4% in normal subjects, patients with chronic liver disease, patients with cancer, patients with other diseases, and children, respectively. The between-tube differences for CD3 exceeding 3% were found in 69 samples (31.2%). The proportion of gamma delta T lymphocytes was 0.81%, 2.46%, 2.50%, and 0.85% in normal controls, patients with chronic liver disease, patients with cancer and patients with other diseases, respectively. No correlation between gamma delta T lymphocytes and CD3(+)CD4(-)CD8(-) T lymphocytes was observed. CONCLUSIONS: The reproducibility of the total T lymphocytes should be improved because of the between-tube difference exceeding 3% in about one third of the cases. Additionally, CD3(+)CD4(-)CD8(-) T lymphocytes were composed of heterogeneous subsets including gamma delta T lymphocytes and their proportion might be considered to be related to individual variation.
