Title: [Pyoderma gangrenosum, subcorneal IgA pustulosis and recurrent neutrophilic pleural and pulmonary diseases in a patient with IgA gammopathy]. Author: Cartier H, Plantin P, Leroy JP, Larzul JJ. Journal: Ann Dermatol Venereol; 1995; 122(3):97-101. PubMed ID: 7486731. Abstract: INTRODUCTION: The term "neutrophilic dermatosis" is normally used to cover a number of dermatoses characterized by their response to corticotherapy or to drugs effective on the neutrophilic polynuclear. Neutrophilic dermatosis was frequently associated with hematologic disease. We study the case of a neutrophilic dermatosis accompanied by a pulmonary involvement and then review the literature on the reported cases of neutrophilic dermatosis with extra-cutaneous localisations. CASE STUDY: A woman aged 54 displayed a pyoderma gangrenosum successively followed by a pustular dermatosis (related to subcorneal pustular dermatosis of Sneddon-Wilkinson) and by a pulmonary involvement not caused by any underlying infection. The laboratory results revealed a benign IgA gammaglobulin. The use of corticotherapy and a relay by dapsone led to the gradual disappearance of the cutaneous and pulmonary lesions. DISCUSSION: Pulmonary involvement have been observed in the Sweet syndrome and in the pyoderma gangrenosum. The neutrophilic lung is diagnosed once a tumorous or infectious cause has been eliminated and on the basis of the response to the cortisone treatment. CONCLUSION: The link between pulmonary involvement and neutrophilic dermatosis is sometimes mentioned but is in fact often difficult to confirm. The positive reaction to corticosteroids could be a diagnostic test.[Abstract] [Full Text] [Related] [New Search]
