Intradermal naevus is the most common pigmented skin lesion commonly called “mole”. It frequently increases in size with time and age. They appear as skin nodules and vary in size, thickness and pigmentation. Some of them may have a few follicles of hair. Although they rarely turn malignant, it is prudent to check for signs of malignant change including change of pigmentation, ulceration and bleeding. The treatment of these lesions is dependent on the size and location.
When it is small and flat or near to vital structures like the eyelashes, they may be removed with laser vapourization. However if it is large and thick, generally excision and direct closure is the method of choice to ensure complete removal. The tissue should be sent for histology if there is any suspicion of malignant change.
