Hand Masses Flashcards
Most common primary bone tumor in the hand
Endochondroma
Well circumscribed radiolucent lesion with stippling or popcorn like appearance
Endochondroma
Nonhereditary form of multiple endochromatosis with unilateral lesions
Ollier disease
Multiple Endochondroma and hemangiomas
Maffucci syndrome
Localized swelling with nighttime pain relieved by NSAIDs
Osteoid osteoma
Central radiolucent nidus with surrounding sclerosis
Osteoid osteoma
Subperiosteal lytic lesion with scalloping of the underlying cortex
Periosteal chondroma
Osseous growth capped with cartilage extending beyond the cortex on a narrow stalk
Osteochondroma
Which hand tumor has the potential for pulmonary metastasis
Giant cell tumors of the bone
Juxta articular lesion with cortical expansion
Giant cell tumor of bone
Campanacci grading system for giant cell tumors
I - well marginated, intact cortex
II - well marginated, expanded cortex
III - Ill defined, soft tissue extension, cortical destruction
Where are glomus bodies located
Stratum reticularis, concentrated at finger tips
Paroxysmal pain, hypersensitivity to cold, pinpoint pain
Glomus tumor
Hildreths test
Lack of pin point pain at glomus tumor site once tourniquet applied to base of digit
Most common benign tumor of the hand
Ganglion cyst
Most common site for ganglion cysts
Over the scapholunate junction between the third and fourth extensor compartments
Most common clinical presentation for degenerative mucous cysts
Nail deformity due to pressure on the germinal matrix
Firm minimally mobile transilluminating mass over DIP joint with pain with movement, thin skin, elderly
Degenerative mucous cyst
Multilobular well circumcised mass in the PIP joint that does not transilluminate
Giant cell tumor
Most common site for hand tumor metastasis
Lung except epithelioid sarcoma which goes to lymph nodes
Treatment for epithelioid sarcoma
Limb sparing wide or radical excision with SNB and adjuvant radiation
Firm ulcerating nodule previously mistaken for infection in the volar digit or palm
Epithelioid sarcoma
Sudden onset pain, swelling, and edema of hand
Pathologic fracture, most likely to be enchondroma
