Pulse Granuloma-Like Reaction on the Forearm Following an Accidental Wound

Pulse granulomas are uncommon reactions to vegetable exogenous matter characterized by the presence of hyaline rings. Although they are usually found in the oral cavity or along the gastrointestinal or respiratory tracts, there are a few cases described outside those regions. We present the first case of a granulomatous reaction with hyaline rings in the skin reaction after an accidental wound and suggest the term pulse granuloma-like to describe lesions that resemble pulse granulomas but with no connection to the gastrointestinal or respiratory tracts. Moreover, we provide a graphic comparison of the hyaline rings observed in our case and the histologic sections of some plants that could have been involved.
