The hand is the site of a great variety of benign lesions and a few malignant lesions but benign ones predominates . • Malignant skin tumors squamous cell carcinoma, basal cell carc. & malignant melanoma are not included in this survey • Tumor like conditions are mentioned
Patients seek advice early because of simplicity of recognition and the disability that attends a small lesion in the hand.
Benign lesions in the hand are first noticed as a palpable mass, an enlarged digit, or a mechanical dysfunction . • Pain may be the presenting symptom in glomus tumor,osteoid osteoma osteoblastoma
Many metabolic and degenerative processes are seen in the hand as radiolucent areas, subchondral degenerative cysts in arthropathies and in gout. • Parathyroid adenoma
Diagnosis • Standard X-ray of the hand of excellent quality and definition are essential • C.T. & M.R.I. & Bone scan • Clinical photo prior to surgery
Angiography in the hand is a useful technique for determining the anatomical extent of the lesion and its relationship to intricate system. Particularly in vascular tumors.
Many lesions in the hand are part of systemic processes. Radioactive isotope scan serves as a total skeletal survey. Any area of increased activity must be judged in light of the over all clinical picture.
Planning Treatment for Hand Tumours • For benign lesions of the digits incisions should be placed in such a way that they do not subsequently interfere with function.
Types of Surgical Approach • Marginal excision. • Curettage & graft. • Wide resection and intercalary reconstruction. • Wide ray resection.
In many instances ray resection may be a cosmetically and functionally superior method of reconstruction than composite tissue grafting.
Caution is needed against overenthusiastic reconstruction with potential loss of the remaining function of the hand.
Enchondroma: Solitary and Multiple The small bones of the hand and have a marked predilection to proximal and middle phalanx and to metacarpal
Cartilagenous tumors • ECCHONDROMA ENCHONROMA Common painless unless pathological fracture
Enchondroma fifth metacarpal • Curettage & graft after path. fracture.
Multiple chondromata Curettage & collapse of the wall
Preoperative Postoperative
Multiple chondromata Maffuci syndrome With cavernous haemangimata showing calcified thrombi
Bone tumors • Osteochndrma • Osteoid osteoma • Giant cell tumor • Osteosarcoma • Secondary deposit
OSTOID OSTEOMA PAINFUL SMALL LESION HOT IN BONE SCAN
BENIGN OSTEOBLASTOMA PAINFULL DENSE TUMOR WITH TENDECY TO RECURRENCE

MULTIPLE HEREDITARY EXOSTOSIS
G.C.T. OF SECOND METACARPAL DIFF. DIAGNOSIS PARATHYROID BROWN TUMOR HEALS AFTER EXCISON OF ADENOMA
G.C.T. INDEX CURETTAGE & GRAFT POSSIBILTY OF RECURRENCE HIGH
G.C.T. DISTAL RADIUS EXCISION & FIBUALR GRAFT
In contrast, many sarcomas in the hand and particularly on the dorsum tend to mimic an inflammatory process with diffuse swelling, local heat and erythema rather than appear as a discrete swelling.
Fibrous Tissue Tumors • Fibroma, localised well differeniated • Palmar fscia contracture, hereditary slowly growing nodules over years
DUPUYTREN,S CONTRACTURE Subcutaneous fibrosis in palmar Facia with with progressive contracure& flexion deformity

Fibrous Tissue Tumors Diffuse Fibromatosis • Diffuse Fibromatosis is a soft tissue tumour of neurolemmal sheath ,muscular fibrous sheath that has a nasty habit of many local recurrences if not completely excised. These tumors can be very painful and disfiguring. They show tendency to malignant destructive recurrence.
