Introduction: IgA pemphigus is a rare, distinct variant of Pemphigus characterized by vesiculopustular eruptions mediated by IgA autoantibodies targeting keratinocyte cell surface antigens, desmocollins 1-3 and sometimes desmogleins 1 and 3. Its classical features have been described in literature but atypical cases have also been documented. This report presents such case posing a diagnostic dilemma. Case Report: A 35-year-old female presented with a 16-year history of intermittent eruptions of multiple hyperpigmented, annular and circinate, desquamating plaques and coalescing flaccid pustules on erythematous bases on the scalp, neck, trunk, and extremities. Histopathologic examination revealed subcorneal pustular dermatitis, and direct immunofluorescence was positive for granular intercellular IgG and IgA deposits in the epidermis. Antinuclear antibody test was negative and C3 level was normal. Antibody tests against desmogleins 1 and 3 were both negative. Topical potent corticosteroid therapy resulted in complete resolution of all lesions in three weeks. Conclusion Diagnostic dilemmas arise when laboratory results do not correlate with clinical findings. Findings of IgA autoantibodies in patients with pemphigus-like skin eruptions led to the diagnosis of subcorneal pustular dermatosis type of IgA pemphigus. Dapsone is the treatment of choice although topical potent corticosteroid alone may provide complete remission in some cases, avoiding the potential adverse effects of systemic therapy

Introduction: Sneddon-Wilkinson disease (SWD) is a rare, recurrent neutrophilic dermatosis presenting as sterile pustules, with a predilection for flexural and intertriginous areas. Case summary: A 49-year-old Filipino female presented with a three-year history of recurrent pustules and papules on the flexural areas of trunk and extremities. Skin punch biopsy was done and histopathology was consistent with subcorneal pustular dermatosis/SWD. She was started on Dapsone but after two weeks of intake, the patient developed generalized erythematous desquamating plaques on the trunk and extremities, with palmoplantar involvement. The patient did not have fever, jaundice, lymphadenopathy, and abdominal tenderness. Laboratory investigation such as complete blood count and liver function tests were normal. The final diagnosis was SWD with hypersensitivity to Dapsone. Dapsone was immediately discontinued and she was shifted to oral colchicine. After six weeks of oral colchicine therapy, the lesions have completely resolved. Patient was in remission for six months thereafter. Conclusion SWD is rare and the drug of choice is dapsone. In instances where dapsone is not suitable, oral colchicine can be an ideal alternative treatment.

Annular pustular psoriasis(APP) is a rare variant of the generalized pustular psoriasis characterized by subacute onset of annular lesion with peripheral advancing pustules. Histologically, it is characterized by spongiform and/or subcorneal pustules which are also found in subcorneal pustular dermatosis(SPD). SPD is very difficult to differentiate from APP, although SPD is thought to be a separate and distinctive entity because of its clinical appearance, characteristic histology, and response to dapsone. We herein report a case of APP showing clinical and histologic features of SPD developed in a patient who had a history of generalized pustular psoriasis.

Subcorneal pustular dermatosis is a chronic, benign, relapsing pustular eruptions characterized histologically by subcorneal pustules which contain abundant neutrophils. We report a case of subcorneal pustular dermatosis occured in a 71-year-old male with typical climcal lesions. Biopsy of a pustule showed a subcorneal cavity with numerous neutrophils, which were also scattered throughout the Malpighian layer below. The result of imrnunofluorescent studies was negative. His eruption is controlled by DDS (25-100mg daily) but the eruptions recur quickly on sessation of the drug.

A case of typieal subcorneal pustular derrnatosis in 16-year-old female was presented. She failed to respond to oral administration of sulfone, however responded favorably to prednisolone.

Introduction: Impetigo herpetiformis is a rare pustular disorder that affects pregnant women. It is also otherwise termed as “pustular psoriasis of pregnancy”, owing to the fact that the pustules are sterile and are not associated with a viral etiology. The classic lesions are erythematous patches or plaques with margins studded with subcorneal pustules spreading centrifugally. A cardinal feature of this disorder is the rapid resolution of lesions after delivery. Case Summary: This is a case report of a 33-year-old female, gravida 3, para 2 (2-0-0-2) at 36 weeks age of gestation who presented with one week history of multiple well defined irregularly shaped erythematous annular patches and plaques with marginal pustules on the trunk and extremities. The lesions began on the trunk spreading centrifugally, sparing the face, palms, soles and mucus membrane. Biopsy showed scale crust in the stratum corneum, the epidermis showed acanthosis, spongiosis and neutrophilic microabscesses with focal vacuolar alteration and small sub-epidermal nests on the basal cell layer. The dermis revealed dilated blood vessels and mild superficial perivascular lymphocytic infiltrates. Patient was given Prednisone and Cetirizine with noted resolution of lesions. Conclusion: Recurrences of impetigo herpetiformis in subsequent pregnancies are common with earlier onset in gestation and are characteristically more severe. The complications are placental insufficiency, stillbirth or neonatal death. Early detection is of utmost importance. Management must be multidisciplinary involving a dermatologist, obstetrician and pediatrician.
