Glomus Tumor   


- Discussion:
    - glomus body is a neuromyoarterial apparatus;
    - glomus is a controlled arteriovenous anastomosis or shunt between terminal vessels;
    - its function is to regulate peripheral blood flow in the digits;
    - majority of the lesions occur in females between the ages of 30 and 50 years;
    - note the association between glomus tumor and neurofibromatosis:
             - ref: The Association Between Glomus Tumors and Neurofibromatosis 
    - in the report by Bhaskaranand K and Navadgi C (2002), the authors reported a series of 18 patients with pain in the thumb or
             finger tips who were diagnosed as having glomus tumour;
             - 14 patients were found to have histopathologically proven glomus tumours, one had a neuroma and three had haemangioma;
             - duration of symptoms before treatment averaged 1.9 years;
             - cold-sensitivity and Hildreth's tests have sensitivities of 100% and 77.4% respectively and specificity of 100%;
             - Love's pin test had a sensitivity of 100% and cold-sensitivity test was 100% accurate;
             - none of these patients experienced recurrence during post op follow up; 
             - ref: Glomus tumour of the hand.

- Clinical Presentation:
    - frequently involves nail bed w/ classic triad of pain, tenderness and cold sensitivity;
           - placing involved digit in ice water will usually reproduce pain within 60 sec;
    - nail bed ridging (and possibily a small blue spot at the base of the nail can be seen;
    - multiple tumors in 25% of patients
    - recurrent excruciating pain
    - may have no visible or palpable signs (ladies should remove nail polish) except for a bluish discoloration;

- Radiographs:
    - x-rays for appositional loss: perforating lesion of the phalanx; 
    - radiographs may also show a shelled out lesion dorsal lesion;
    - radionuclide scanning

- Treatment:
    - in terms of excision the tumor is usually well encapsulated and can be shelled out;
    - surigical through lateral approach or thru nail bed (see nail bed removal);
    - lateral approach:
          - preferred technique if the lesion is on the margin of the nail;
          - elevate the entire flap, which includes the nail plate, nail bed, and periosteum superiorly in order to excise the circumscribed lesion on the undersurface of the flap, or within bone;
          - flap is then replaced and held with nylon sutures
