mesenchymal tumors Flashcards
fibroma
a true neoplasm where the fiber starts growing
rare
the most common “tumor” of the oral cavity
fibroma
t/f fibromas can happen anywhere in the body
true
peripheral ossifying fibroma location
outside the bone and on the gingiva
t/f peripheral ossifying fibroma is a rare lesion that is reactive
false, true. it is a common lesions that is considered reactive
t/f the distinction bt a peripheral and central ossifying fibroma is important for the tx process
true
prognosis for peripheral ossifying fibroma
good, high recurrence (just cut off)
fibrosarcoma
malignant tumor of fibroblasts
pyogenic granuloma
“pregnancy tumor”
reactive lesions to irritation or injury
t/f a pyogenic granuloma is non-neoplastic
true
what is a better name for a pyogenic granuloma
lobular capillary hemangioma (it is a vascular tumor)
if a pyogenic granuloma happens in women, when do you remove it
after pregnancy
t/f in a gingival excision of a pyogenic granuloma, you should extend down to the periosteum
true
peripheral giant cell lesion
vascular, gingival (or on an edentulous ridge), tumor from the pdl or periosteum
most common “gum bumps”
5 p’s:
- pyogenic granuloma
- peripheral ossifying fibroma
- peripheral giant cell granuloma
- “plain” fibroma
- parulis
lymphangioma
benign growth of lymph vessels
does a lymphangioma blanch
no (not vascular)
are lymphangiomas congenital
maybe. half of all lesions are noted at birth, and 90% are before age 2
features of lymphangiomas
commonly on the tongue
cluster of translucent vesicles (frog egg appearance)
angiosarcoma
malignancy of blood vessels
traumatic neuroma
proliferation of axons after trauma (nerves try to grow and reattach to each other)
t/f a traumatic neruoma is painful
yes. on palpation
schwannoma
benign neoplasm of schwann cells
t/f a schwannoma is painful
no
