Cutaneous silica granuloma: a lesion that might be clinically underdiagnosed

Cutaneous silica granuloma is a poorly understood, uncommon condition. There have been relatively few reports of cutaneous silica granuloma despite the well-known ubiquitous nature of silica in the environment. The characteristic latency period between the time of silica exposure to the time of clinical onset of granuloma, lack of clear-cut histories of exposure in most cases and likelihood of spontaneous resolution, may challenge the diagnosis. Thus, cutaneous silica granuloma might be a lesion that is often underdiagnosed. Here we describe a patient with characteristic findings of cutaneous silica granuloma.
