Abstract

A mucocele is a common, benign lesion of the oral cavity that develops following the extravasation or retention of mucous from a major or minor salivary gland. A pyogenic granuloma (PG) is also a common, benign condition characterized by proliferating capillaries that affect the skin and mucous membranes. The concurrent occurrence of a mucocele and a PG lesion has rarely been reported in the medical literature. This case study reports such a finding in a 16-year-old patient who presented to our department.

  Fig. 2 (A) The tumor consisted of two components (H&E, ×40). (B) One component was a lobular structure surrounded by acanthotic epidermal collarette in the upper dermis. There were multiple dilated vessels surrounded by myxoid stroma in the lobular structure (H&E, ×100). (C) The other component was unilocular cyst in the lower dermis. There were infiltration of inflammatory cells and formation of granulation tissues were evident (H&E, ×100).
