A 69-year-old woman presented with a 2-month history of
painful lesions, which had initially appeared on the axillae,
and had spread rapidly to the infra-mammary folds and
groin. On physical examination there were erythematous
papules coalescing into plaques and erosions in the in-
tertriginous areas, oozing purulent fluid, including in the
inframammary folds and groin (Fig. 1 A, B). There was
no lymphadenopathy, lymphangitis or mucous membrane
involvement. The patient had no other systemic symptoms.
Results of laboratory tests, including urea, electrolytes, liver
function and blood cell counts were normal. A skin biopsy
was obtained, which showed the presence of sparse inflam-
matory infiltrates with numerous plasma cells (Fig. 1 C).
