Salivary gland mucocele, also salivary mucocele and mucocele, is a benign lesion of the head and neck.

General

  • Benign.
  • Infected mucocele = mucopyocele.

Gross

Features:

  • Floor of mouth lesion.

Microscopic

Features:[1]

  • Granulation tissue-like and pseudocyst-like.
    • Granulation tissue-like:
      • Fibroblasts.
      • Small caliber blood vessels.
      • Histocytes.
      • Neutrophils.
    • Pseudocyst:
      • No epithelial lining.
      • Poorly circumscribed.
  • Pale pink extracellular material (mucous) - key feature.
  • +/-Granulomas.[2]

LESION, LEFT LOWER LIP, EXCISION:
- BENIGN MUCOCELE.

Micro

The sections show a stratified squamous epithelium with a thin layer of parakeratosis, minor salivary glands, and a well-circumscribed cystic lesion.

The cystic lesion has a mildly fibrotic appearing wall, is lined by histiocytes intermixed with rare lymphocytes, and contains mucous and macrophages. No significant nuclear atypia is identified. Mitotic activity is not readily apparent.
