Oral Health Pathology and Treatment

Granuloma annulare is a benign cutaneous inflammatory disease, whose lesions have spontaneous improvement in two years in 50% of cases, but there is recurrence in 40% of patients. Treatment may be topical, intralesional or systemic. The use of phototherapy with narrowband UVB is highlighted, whose mechanism of action in this disease is still unclear, probably related to the inhibition of T lymphocytes. Herein, a case of a disseminated granuloma annulare of difficult therapeutic management is described. It was treated with narrowband UVB phototherapy twice a week for six months, with good clinical improvement, being a good low-risk therapeutic option and that, in this case, provided quick and satisfactory response.
