Mid-30’s FM w/progressive conductive hearing loss. Clin dx: otosclerosis

Intraop: stapes fixed, remainder of ossicular chain mobile.

Squamous cell carcinoma of the edentulous alveolar ridge and palate. Cut surface (ms=maxillary sinus; nc=nasal cavity); corresponding low mag image; endophytic (arrow) with cystic cuniculatum-like growth; additional cystic change in scca.

Submandibular sialolith is a gross-only specimen for us. However…the interesting surface texture piqued my interest. Intact appearance, sectioned, faxitron (in our lab) and low mag histology with arrows highlighting the textured region.

Will find SNP tissue (arrows in these two low magnification examples) near fungiform, foliate and/or circumvallate papillae of the tongue.

Idiopathic gingival papillokeratosis with crypt formation.

Uncommon. Generally located along anterior maxillary gingiva in young people. Asymptomatic plaque(s), usually bilateral and white in color. No known risk of transformation.

✅ Squamous Cell Carcinoma (acantholytic type)
Pseudoglandular spaces due to loss of cohesion between squamous cells
Key: NO true glandular differentiation (i.e., no mucin)
Diffusely p40 positive, Ber-EP4/EpCAM (adenocarcinomas) negative

#ENTPath #PathSky

❌ Adenosquamous Carcinoma
Requires TWO distinct malignant components:
1) SCC
2) adenocarcinoma (true glands, often mucin-producing)

#ENTPath #HeadNeckPath #PathTwitter #PathSky

❌ Mucoepidermoid Carcinoma (neither SCC or adenocarcinoma)
Admixture of mucous cells, intermediate cells, and epidermoid (squamoid) cells.
Often forms cysts (low grade) and solid areas (high grade)

Juxtaoral organ of Chievitz that was too good not to share.

Should be (incidentally) found in sections containing muscle/fascia medial to the medial pterygoid muscle, so often seen in larger mandibular or buccal SqCC resections.
