2. Hand tumors arise from any tissue—skin,
subcutaneous tissue,tendons, nerve, blood
vessels, and bone.
Hand tumour can be classified in many
different ways which may cause confusion
between types and their management plan.
This lecture mainly concerned about how to
classify them in simple and accurate way.
3. Benign tumors account for 95% of hand
masses if skin cancers are excluded.
Ganglions represent 60 to 70% of hand
tumors, followed in frequency by inclusion
cysts, warts, (verruca vulgaris),giant cell
tumors of tendon sheaths, foreign body
granulomas,lipomas and hemangiomas.
4. Hand tumour can be classified into major 3
type:
1. Benign tumors.
2. Malignant tumors .
3. Tumorous conditions .
5. Each of benign and malignant type can
further be classified according to tissue of
origin into:
1. Bone tumour.
2. Soft tissue tumour.
3. Skin tumour.
6. Benign tumours
1. Bone tumours:
Enchondromas
Osteochondromas
Osteoid oseoma.
Benign osteoblastoma
Aneurysmal bone cyst
Giant cell tumors of bone
Synovial chondromatosis .
Osteophyte
Chondromixoidfibroma
7. Enchondrom
the most common primary hand bone tumor,occurs
chiefly in the 3rd and 4th decades It occurs most
commonly in the phalanges, usually in the proximal
phalanx
9. Osteoid osteoma
is an unusual hand tumor occur in phalanges, metacarpals,and
carpal bones, and presents in the 2nd and 3rd decades of life
with aching pain that is greatest at night. classically relieved by
aspirin
40. Skin
Benign tumour of skin can be classified
according to structure of origin in the skin:
epidermal layer:
verruca vulgaris(wart).
Keratosis:seborrheac,actinic,solar,irradiati
on.
Prokeratosis
Cutaneous Horns
Keratoacanthoma
52. Malignant hand tumours
Bone :
Osteogenic Sarcoma.
Chondrosarcoma.
Ewing Sarcoma.
BoneTumors of the Hemopoietic System
e.g. Malignant lymphomas
Metastatic lesion
63. Tumorous conditions
Its usually not true tumour we can subdivide
them to :
1. Cystic leision:
Ganglion cyst.
Epidermoid cyst (inclusion cyst) .
Sebaceous cyst
