leiomyoma

Leiomyomas are benign tumors of smooth muscle that most commonly occur in the uterus, gastrointestinal tract, and skin. Leiomyomas of the oral cavity are rare. Most of these probably have their origin from vascular smooth muscle (as in this case)

Odontogenic myxoma

✨rare benign tumour originated from odontogenic ectomesenchyme.

✨Radiographically, an unilocular or multilocular radiolucent image may be observed, with or without clearly defined borders.

I saw it, I gotta post it.

I don't make the rules.

Biopsy from posterior mandible
The clinician is worried about metastatic malignancy
This is what you under the microscope, what is your diagnosis?

Fracture callus
Left: Bone formation with osteoblastic rimming
Right: Cartilage can look cellular, atypical and with mitosis
Fracture callus can look worrisome on histology and be misinterpreted as a neoplastic process
Dr. Nielsen #USCAP2024 #BSTPath #pathology #PathX …

A clinician sent a biopsy from the mandible and wondered whether it is ‘’Goretex”?

Let’s be honest, I never heard of such material.
I checked it out and it seems correct✨

Goretex is a chin augmenting material, looks interesting under the microscope, isn’t it?

Pathologists, beware that infectious mononucleosis can mimic DLBCL! Be careful. #pathology #hemepath #PathTwitter

Inverted follicular keratosis

▫️Benign, endophytic follicular tumor with characteristic presence of squamous eddies
▫️Most commonly on the head and neck (~90% of cases) with predilection for cheeks and lips
▫️Multiple lesions may be associated with Cowden syndrome.
