Soft Tissue Differential Diagnosis Flashcards
pseudomembranous candidiasis
- multiple white plaques
- wipes off leaving erythematous area
- found commonly in immunocompromised patients
hyperplastic candidiasis
- does not wipe off
- leukoplakia appearance
atrophic candidiasis
- aka erythematous candidiasis
- clinically appears erythematous
- can be seen with central papillary atrophy or median rhomboid glossitis or denture stomatitis (due to poor hygiene)
- Bump on gums
- location: lingual gingiva
- has not displaced teeth
- no radiographic calcifications
- sessile, nodule, ulceration, erythema
- firm
- middle aged female
- BUMP ON GUMS DIFFERENTIAL DIAGNOSES:
1) pyogenic granuloma
2) peripheral ossifying fibroma
3) peripheral giant cell granuloma
What is the histology of a peripheral giant cell granuloma:
chocolate chip cookies (multinucleated giant cells)
Most common salivary gland tumor:
pleomorphic adenoma (AKA benign mixed tumor)
- middle aged females
- painless
- slow growing
- max of myoepithelial and ductal epithelial elements
- ENCAPSULATED
Differential diagnosis for bump on gums:
- pyogenic granuloma (can occur on tongue)
- peripheral ossifying fibroma (exclusive to gingiva)
- peripheral giant cell granuloma (exclusive to gingiva)
How would you describe this type of inflammation?
What are some differential diagnoses that present with this type of inflammation?
Granulomatous inflammation;
(pattern of chronic inflammation)
(aggregates of epithelioid macrophages)
(multinucleated giant cells, mononuclear leukocytes, principle lymphocytes, and occasionally plasma cells - peripehrally)
(fibrosis variable)
Differential diagnosis:
1. crohns disease
2. deep fungal infections (ex: ccoccidiomycosis)
3. Tuberculous (caseous necrosis)
How would you describe this histological slide?
What disease is seen with this presentation?
granulation tissue; pyogenic granuloma
List the differential diagnosis to the following presentation
- chemical burn (aspririn)
- toothpaste allergy (SLS)
- cheek biting (trauma)
- psuedomembraneous candidiasis
Where is the most common intraoral-extranodal are for lymphoma?
hard palate
You see a bump on the hard palate, and upon palpation you note that tit is squishy and bogging. What is a good diagnosis?
lymphoma
Most common salivary gland tumor:
What is it comprised of histologically?
pleomorphic adenoma; myoepithal and ductal cells
(most common in palate)
Your patient presents with this histology:
- monomorphic adenoma
- most common location is upper lip
- histology; unitform pattern single layered cords of columnar or cuboidal epithelium
A malignant salivary gland tumor (the low grade version of this mimics a mucocele)
- Mucoepidermoid carcinoma
- most common MALIGNANT salivary gland neoplasm
- middle-aged females
- clinically mistaken for a mucocele
Histology:
- mucous producing cells
- epidermoid (squamous) cells
- may be cystic and/or solid
