Lecture 9 - Oral Non-Squamous Malignancies Flashcards
Leukemia
Originates in bone marrow
Myeloid (affects RBC precursor)
Lymphoid (affects Lymphotic precursor)
Acute or Chronic
Leukemia Diagnosis
Via peripheral blood and bone marrow biopsy
Leukemia Radiographic Appearance
Teeth floating in air
Leukemia Systemic Findings
Hepatosplenomegaly Lymphadenopathy Thrombocytopenia Anemias Fever
Leukemia Oral Manifestations
Oral ulceration
Candidiasis
Gingival hyperplasia (“boggy”)
Gingival hemorrhage (platelets <10,000)
Leukemia Histologic Findings
Monotonous proliferation of poorly differentiated cells (RBC or WBC precursors)
Abnormal mitosis
Hodgkin’s Lymphoma
Malignancy of lymph nodes
Oral lesions very RARE
Why are we learning this?
Hodgkin’s Lymphoma Epidemiology
Bimodal: 15-30yr and >50yr
Males
75% cervical and supraclavicular nodes
5-10% axillary and mediastinal nodes
Hodgkin’s Lymphoma Systemic Findings
Non-tender lymph node enlargement Weight loss Fever Night sweats General pruritis
Hodgkin’s Lymphoma Histologic Findings
Reed-Sternberg cells (giant, multi-nucleated cells with prominent nucleoli)
Non-Hodgkin’s Lymphoma
Malignancy of lymph nodes
Oral lesions most common in B-cell origin
Adults
Non-Hodgkin’s Lymphoma Oral Manifestations
Soft tissue lesions:
-Non-tender, diffuse, “boggy” swelling in buccal vestibule, gingiva, and posterior hard palate
Bone lesions:
- Vague pain
- Parasthesias
- Ill-defined radiolucencies
- Bony expansion with cortical perforation
Non-Hodgkin’s Lymphoma
Infiltrative, monotonous proliferation of poorly differentiated lymphocytic cells
Burkitt’s Lymphoma
Undifferentiated B-cell lymphoma
Associated with EBV
t(8;14)
Good prognosis with chemotheraphy
Osteosarcoma Oral Manifestations
Tooth mobility and root resorption Swelling Pain Parasthesia Nasal obstruction
