30 year old male presents to the clinic with pain in his left ankle. Radiographs shown exhibit
a soap bubble appearance lesion, with extensive destruction of medullary and cortical bone.
What is the likely diagnoses? - CORRECT ANSWER✔✔- giant cell tumor
What is a tumor that is typically seen in the third or fourth decades of life. It presents largely
in the epiphysis, but can cross over to the metaphysis and diaphysis, eventually damaging the
subchondral plate. It can also undergo malignant transformation and may be associated with
hyperparathyroidism? - CORRECT ANSWER✔✔- Giant cell tumor
A 36-year-old female presents with lytic distal tibial lesion and a lung nodule on chest x-ray.
Which of the following is highest on her differential diagnosis? - CORRECT ANSWER✔✔-
giant cell tumor
A 9 year old patient presents with an angular deformity of his tibia. X-rays show a hazy,
ground-glass appearance at the site of angulation. What is the most likely diagnoses here? -
CORRECT ANSWER✔✔- Fibrous dysplasia
, A patient presents with hyper melanin pigmentation. Doctors suspect a disorder that affects
her endocrine system. What bone lesions could you possibly suspect this patient develops? -
CORRECT ANSWER✔✔- Fibrous dysplasia
What bone tumor is tpically a multiloculated lucent lesion with a sclerotic rim. They are
located eccentrically in the metaphysis, adjacent to the physis. As the patient ages, they seem
to migrate away from the physis. They have no associated periosteal reaction, cortical breach
or associated soft tissue mass? - CORRECT ANSWER✔✔- Nonossifying fibroma
Radiographs of which bone tumor demonstrate well defined, lucent, central medullary lesions
that calcify over time , 1 to 10cm in size metaphyseal location when they first appear, appear
more diaphyseal as the long bone grows, "pop-corn" stippling, arcs, whorls, rings? -
CORRECT ANSWER✔✔- Enchondroma
The syndrome associated with multiple enchondromas is _________? . Multiple
enchondromas with hemangiomas is exhibited in _________?. - CORRECT ANSWER✔✔-
Ollier's disease
Marfucci's syndrome
What bone tumor clinically present as a painless mass or bony swelling? Radioigraphic
findings typically include a lesion comprising of both cortical and medullary bone with an
overlying cap of hyaline cartilage. In very rare instances, they can transform into malignant
chondrosarcoma. - CORRECT ANSWER✔✔- Osteocondromas
What is the name of the tumor that is a benign tumor, and usually occurs in the epiphysis;
usually is seen when the growth plate is open. The tumor is usually painful and on imaging
will classically demonstrate surrounding edema and enhancement on MRI? - CORRECT
ANSWER✔✔- Chondroblastoma
Significant soft tissue swelling and pain is seen in a 15 year-old-male along the epiphysis of
the right lower extremity. What primary tumors would be most likely? - CORRECT
ANSWER✔✔- Chondroblastoma
What is the best treatment modality for an isolated Ewing's sarcoma identified in the foot? -
CORRECT ANSWER✔✔- Chemotherapy followed by surgical excision followed by
additional chemotherapy
