Pemphigus vulgaris has never before been associated with silicosis, although there are many reports of silicosis accompanied by several autoimmune diseases such as progressive systemic sclerosis, systemic lupus erythematosus, dermatomyositis or rheumatoid arthritis. We observed a patient with pemphigus vulgaris accompanied with silicosis. The patient was a 75-year-old man with a 2-month history of repeated oral erosions and blisters on the back, thighs and axillas. Histological examination showed suprabasal cleavage with acantholysis. Immunoblotting analysis demonstrated binding of the patient's serum to the 130-kD pemphigus vulgaris antigen (desmoglein 3) and the 160-kD pemphigus foliaceus antigen (desmoglein 1). The patient has radiographically been diagnosed as having silicosis. An elevated serum IgG, antinuclear antibody, anti-ssDNA, antimicrosomal antibodies and a biologically false-positive reaction to the Wassermann test were also detected. Although the clinical symptoms improved after treatment with systemic steroids, the patient died due to pneumonia. This is the first reported case in which the characteristics of both pemphigus vulgaris and silicosis could be detected.

We report on a sixty-seven year old miner with pemphigus vulgaris characterised clinically by a three month history of relapsing oral lesions and blisters/erosions on the trunk, axillae and extremities, histologically by suprabasal cleavage due to acantholysis, immunologically by the epidermal intercellular net-like pattern due to deposits of IgG- and IgM-antibodies and complement C3 in the direct immunofluorescence as well as by serum antibodies to desmoglein 3 (130 KD) and plakoglobin (85 KD) by immunoblotting analysis. Silicosis has already been known for 6 years. In addition, antinuclear antibodies, anti-ssDNA-antibodies and anti-topoisomerase antibodies were found. Clinical improvement and clearing of skin symptoms could be achieved by systemic steroids in combination with cyclophosphamide. However, the patient died of sepsis deriving from recalcitrant pneumonia. Although the association of silicosis with various autoimmune diseases such as systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis and dermatomyositis has been reported many times, our patient is, to the best of our knowledge, the second case with features of the two diseases: pemphigus vulgaris and silicosis.
