This document provides a classification of tumors and tumorous conditions of the hand. It begins by explaining that hand tumors can arise from any tissue, including skin, subcutaneous tissue, tendons, nerves, blood vessels and bone. It then classifies tumors into three main types: benign tumors, malignant tumors, and tumorous conditions. Within each type, tumors are further classified based on the specific tissue of origin, such as bone tumors, soft tissue tumors, and skin tumors. Numerous specific tumor examples are listed and briefly described under each tissue of origin classification. The document concludes by defining tumorous conditions as usually non-cancerous lesions, separating them into cystic and non-cystic conditions with representative examples.

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

8. Osteochondroma
consists of a bony prominence at the level of the
metaphysis covered by a cartilaginous cap.

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

10. Giant cell tumors of bone

11. Aneurysmal bone cyst

12. Synovial chondromatosis .

13. Osteophyte

14. Chondromixoid fibroma

15. 2.Soft tissue tumours:
 Muscl :
 leiomyoma.
 Tendon:

of the tendon Sheath).
 XanthomaTuberosum

16. leiomyoma

17. fibroma of tendon sheath

29.  Tumors of Peripheral Nerves:
 Neurofibroma.
 Schwannoma.
 Granular CellTumor.
 Neurothekeoma (pacinian neurofibroma).
 INTRANEURALTUMORS OF NONNEURAL
ORIGIN
Numerous nonneural tumors have been reported in
peripheral nerves: lipomas, lipofibromatous
hamartomas, and hemangiomas.

30. Neurofibroma

32. Granular Cell Tumor

33. Neurothekeoma median nerve

34.  VascularTumors:

 Post traumatic vascular lesion:
Traumatic fistulas
Atherosclerotic aneurysms.
 Pyogenic granuloma.
 GlomusTumor

35. Hemangioma

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

41. verruca vulgaris(wart).
