Introduction: Solitary reticulohistiocytoma (SRH) is a rare condition that presents as a brownish solitary nodule, measuring less than 1 cm. It affects the head and neck regions of middle-aged individuals and is microscopically characterized by an infiltrate of histiocytes and giant cells with an extensive cytoplasm with an aspect of "ground glass." It is not related with systemic diseases. When it appears as multiple lesions, it may be confused with multicentric reticulohistiocytosis, which can be malign.
