**5. Conclusions**

Cause-based treatment options are more beneficial than palliative management options. Therefore it is crucial for physicians to make a sound clinical examination and take a through patient history [3]. Biopsy should be considered if an ulcerative lesion with an unknown etiology shows no signs of healing after two weeks, or if the lesions is not responsive to a treatment aimed at a probable known etiology. Ulcers of less than 5 mm diameter are advised to undergo an excisional biopsy, whereas for larger ones an incisional biopsy is suggested [6].
