[Pemphigus vegetans, a clinical type of chronic pustular dermatitis of Hallopeau].

A 49-year old woman had an eruption resembling 'dermatite pustuleuse chronique en foyers a progression excentrique' as initially described by Hallopeau. Numberous vegetating lesions occurred over the genitocrural, pubic, umbilical and submammary regions. The finger-nails showed onycholysis and sterile pustules. No bullae were seen at any time. Histopathological study revealed the presence of acantholysis. Direct immunofluorescent microscopy showed IgG deposits in the intercellular epidermal space. The titer of pemphigus antibody was 1/1,600: the results of these immunofluorescence studies on early pustular lesions as well as vegetating lesions support the view that Hallopeau disease belongs to the 'pemphigus group'. The patient was treated first with oral prednisone (80 mg/day). In twelve months of follow-up care, the vegetating lesions disappeared completely, leaving hyperpigmentation. Prompt recurrence of lesions was observed when corticosteroids were discontinued; reinstitution of this therapy was followed by their regression. A difference exits between pemphigus vegetans of Hallopeau and pemphigus vegetans of Neumann: (1) the Hallopeau type begins with pustules as the primary lesions, followed by vegetations, with a lack of bullae and a preference for flexural areas. Immunofluorescence studies will be the deciding factor in separating pemphigus vegetans of Hallopeau from pyoderma vegetans. (2) The Neumann type is a variant of pemphigus vulgaris in which the denuded areas have a tendency to heal with papillomatous formations. It begins and ends with bullae.

[Pyoderma vegetans as an early sign of HIV infection].

Skin and mucosal lesions are described in a 40-year-old man who suffered from HIV infection in the stage of secondary diseases. The diagnosis was supported by demonstration of antibodies to HIV in the immune blotting test. The clinical manifestations were reduced to steady fever, generalized lymphadenopathy, pyoderma vegetans and chancriform pyoderma, candidiasis of the oral cavity, and seborrheic dermatitis, HIV infection was diagnosed 4 years after the appearance of pyoderma which initially was amenable by external antibacterial agents and then became resistant to them. Eruptions of pyoderma vegetans simulating wide condylomas were located in inguinal folds, on the internal surface of the thighs and scrotum; the chancriform focus was located in the internal preputial layer. The treatment with azothymidine combined with antibacterial and antimycotic agents led to the improvement of the patient's general status and to the reduction of local lesions. However, on recommendations of an unknown witch doctor who started treating him with the aid of reflexotherapy, phytotherapy and bioenergetic actions the patient stopped receiving the treatment prescribed and did not report for control examinations. After 5 months he died of brain edema.

The comparative pathology of non-viral bullous skin diseases in domestic animals.

In a review of non-viral bullous skin diseases of domestic animals and a 4-year study of cases presented to the New York State College of Veterinary Medicine, we found 15 diseases: pemphigus vulgaris, pemphigus vegetans, pemphigus foliaceus, pemphigus erythematosus, bullous pemphigoid, systemic lupus erythematosus, dermatitis herpetiformis, toxic epidermal necrolysis, drug eruption, epidermolysis bullosa, epidermolysis bullosa simplex, familial acantholysis, bovine congenital porphyria, impetigo and subcorneal pustular dermatosis. The 15 diseases were placed in five categories: autoimmune, immune-mediated, hereditary, bacterial and idiopathic. A histologic classification of these disorders based on the site of blister formation and other important clinicopathologic, histologic and immunopathologic findings was developed.
