GRANULAR CELL TUMORS
---------------------------------------------------


I have a patient with multiple (10) granular cell tumour on his trunk and
limbs. Textbooks suggest around  1-3 % of granular cell tumour are
malignant. Should they all be excised (as the risks of malignancy may
multiply) ?

Don't remove them.  We have all seen many granular cell tumors and
clearly 1-3% of them do not become malignant.  Please note that granular
cell tumors, particularly of the tongue, may show pseudocarcinomatous
epidermal hyperplasia in the overlying epidermis that may be
misinterpreted as SCC.
