| Abstract|| |
Pemphigus vegetans is a rare variant of pemphigus vulgaris characterized by pustules and/or papillomatous vegetations, preferentially affecting intertriginous and periorificial areas. It has two subtypes: Hallopeau variant and Neumann variant. Cerebriform tongue, a morphology with typical pattern of sulci and gyri over dorsum of the tongue, is a well-known sign in pemphigus vegetans. We are presenting an unusual case of pemphigus vegetans with extensive involvement of mucosae, trunk, extremities including both extensors and flexural areas with verrucous paronychia and fissured tongue. During clinical exam we recognized multiple cutaneous vesicles, erosions and ulcers on mucosal sites. Clinical, histopathological, and direct and indirect immunofluorescence findings were compatible with pemphigus vegetans. Patient had completed her family so treated with intravenous dexamethasone-cyclophosphamide pulse (DCP) regimen with excellent response.

| Introduction|| |
Pemphigus vegetans is the rarest form of pemphigus vulgaris comprising only 1%-2% of all cases and considered as a benign subset. It exhibits vesicles, bullae, pustules and erosions that consequently form vegetating masses particularly in the flexures. It has two subtypes: Neumann and Hallopeau variants. The former is a belligerent non-healing bullous disorder contradictory to self remitting benign variant of Hallopeau. These bullous and pustular variants described by Neumann and Hallopeau reflect the clinical spectrum of pemphigus vegetans itself. Hallopeau type, initially characterized by pustular lesions that, after rupturing, merge and gradually evolve into vegetating erosions. The disease typically affects the axilla, inframammary, inguinocrural, intergluteal folds, where semi-occlusion, maceration, and mixed infections continuously incite exudation and granulation tissue formation (wet pemphigus vegetans). In non-intertriginous locations, the vegetating buttons can dry out to change into warty, fissured, painful, seborrheic keratosis-like lesions (dry pemphigus vegetans). We herein report an unusual case of pemphigus vegetans which needs documentation because of extensive involvement.
| Case Report|| |
A 30-year-aged Hindu female from the remote village of Himachal, hospitalized for painful oro-genital ulcerations with brownish black thick, raised itchy lesions over abdomen and back, limbs, axillae, groin and perianal region for past 2 years. The skin lesions started with itching followed by eruption of clear fluid filled blisters which used to rupture quickly and resulted into crusted erosions. Subsequently crusted lesions transformed into thick, elevated, moist vegetating masses in 2-3 weeks duration. Few areas revealed pustules in between verrucous plaques. She was treated with multiple courses of antibiotics, without much relief at peripheral health facilities. The lesions progressively increased in size and disseminated over trunk, extremities, perianal area as well as genital mucosa and digital involvement. Past history did not suggest sexually transmitted disease and drug rash or familial affliction.
Mucocutaneous examination revealed well-defined, multiple, skin colored to dark brown, elevated, indurated, plaques of variable size approximately 1 × 1 cm to 10 × 18 cm with verrucous, vegetating moist surface over abdomen [Figure 1]a, inframammary region, back, [Figure 1]b both arms [Figure 2], axillae, perianal area [Figure 3]a, third and fourth digits of right hand [Figure 3]b, groin, thighs [Figure 4]. Some plaques were of annular in shape with central clearing. Lesions over labia majora and perianal region showed evidence of fissuring and oozing. Few vesicular lesions and erosions were present over upper back.

Palate, tongue and gingivae revealed multiple painful erosion and ulcers with erythematous base and regular margins. Tongue was fissured and cerebriform [Figure 5]. Genital mucosa also revealed multiple erosions. Nasal and ocular mucosae were spared.
Subungual hyperkeratosis, discolored and thin nail plate with verrucous paronychia and flaccid bullae on third and fourth digits were also seen.
General physical and systemic examination revealed nothing abnormal.
Complete blood count demonstrated peripheral eosinophilia (25%), ESR and C-reactive protein levels were normal. KOH examination of exudate, urine, stool analysis, X-ray chest and thyroid function tests did not reveal any abnormality. HIV serology and VDRL tests were non-reactive. Nicolsky's sign was positive over trunk. Tzanck smear showed acantholytic cells and eosinophils. Gram staining of exudate revealed mixed infiltrate predominantly eosinophils with no bacteria and staining for acid bacilli was negative. Direct immunofluorescence revealed intercellular immunoglobulin G (IgG) deposits in epidermis [Figure 6]. Indirect immunofluorescence revealed IgG autoantibodies directed against desmoglein (Dsg) 3.

Histopathological examination showed stratified squamous epithelium with marked hyperkeratosis, mild acanthosis, papillomatosis, spongiosis with vacuolar degeneration of basal layer and focal supra-basal cleft formation [Figure 7] with acantholytic cells and eosinophilic exocytosis. Dermis revealed mild focal perivascular lymphocytic infiltrate mixed with eosinophils.

The investigations associated with the patient's clinical profile confirmed the diagnosis of pemphigus vegetans Neumann type. She was treated with intravenous dexamethasone-cyclophosphamide pulse (DCP) as the patient had completed her family of two children, consisting of 100 mg dexamethasone with 500 mg of cyclophosphamide on day 2 along with topical clobetasol ointment. The pulse therapy was repeated at 4 weeks intervals. In the intervening period, patient was given daily oral cyclophosphamide 50 mg. After two DCP pulses, patient had significant regression of lesions. Complete clearance with residual hyperpigmentation was achieved after five DCP pulses [Figure 8]. DCP was continued for nine pulses but now she is lost to follow up.

| Discussion|| |
Pemphigus vegetans is a rare skin disease, speculated to be a reactive pattern of skin to an autoimmune insult of pemphigus vulgaris. It is clinically characterized by vesicles, erosions results in thick hyperkeratotic masses especially in the intertriginous regions with involvement of oral mucosa invariably. It was first described by Neumann in 1876. Literature describes two subtypes: the Neumann type and the Hallopeau type. Neumann type has clinically unremitting and prolonged course, responding less to therapy. The skin lesions are vesicles, bullae forming vegetating masses studded with pustules along with oral erosions. Verrucous masses limited to the oral cavity followed by a rapid spread to the lips with only symptom of burning and itching have been reported. In rare instances, the lesions over tongue may persist for years and without recurrence of lesions on any part of the body. The Hallopeau is a milder form beginning with pustules and ultimately forming vegetating plaques. It may have spontaneous remission. Ulcerative patches around the mouth that gradually extended into his nose with scattered patches over the scalp and glans penis with oozing of pus, are also reported as unusual presentations. Cases have been described with lesions over lips, tongue, nose, nail folds, feet, perianal region and groin.,,,, Cerebrifom tongue also seen in the present case has been quoted as an eponymous sign, a clinical sign or a clue for pemphigus vegetans in cases of bullous dermatoses of flexures.
The standard treatment of this disease is with systemic steroids in the form of oral prednisolone or injectable dexamethasone on daily basis or DCP therapy.,,
Our patient had most of the lesions over the extensors rather than flexures which were different from the usual presentation. To the best of our knowledge to date no such case with an extensive involvement had been described with excellent response to DCP regimen.
