Cribriform adenocarcinoma of the minor salivary gland, abbreviated CAMSG, is a rare malignancy of the salivary gland, typically of the tongue.[1]

It is also known as cribriform adenocarcioma of the tongue, abbreviated CAT.

General

  • Rare.
  • Typically tongue - first described there.[2]
  • Good prognosis[1] - on limited data.

Microscopic

Features:

  • Typically covered by an intact squamous epithelium.[1]
  • Growth patterns - cribriform and solid.
  • Cytology similar to papillary thyroid carcinoma.[1]
    • Irregular nuclear membranes (raisin-like nuclei).
    • Nuclear overlap.

IHC

Features:[1]

  • CAM5.2 +ve (12/12 cases).
  • CK7 +ve (12/12 cases).
  • CK8 +ve (12/12 cases).
  • CK18 +ve (12/12 cases).
  • S-100 +ve (12/12 cases).
  • Vimentin +ve (12/12 cases).
