Abstract
- Interstitial granulomatous dermatitis (IGD) is a rare disease that has been associated with multiple systemic diseases, particularly autoimmune conditions like rheumatoid arthritis and systemic lupus erythematosus. IGD has a variable clinical presentation and highly characteristic histological features of interstitial infiltrate of histiocytes between the degenerated collagen bundles. Here we report the case of a 63-year-old woman who presented with a 3-month history of multiple asymptomatic erythematous papules on the bilateral aspects of the trunk. A histopathological examination of the lesion showed an interstitial lymphohistiocytic infiltrate in the dermis. There were also foci of palisading histiocytes along with degenerating collagen bundles.
