Introduction: Skin complaints are a common cause for visits to the primary care physician. This case report describes a patient diagnosed with lichen planus, which is an uncommon health problem. It is a chronic, inflammatory, immune-mediated disease of unknown etiology that affects from 0.2 to 5% of the population. Case report: A 60 year-old male patient, previously in good health, saw his family physician in October 2014 complaining of pruritic papules on the hands, trunk, back and feet, which appeared one month before. He also had pain on pressure over his fingernails. Physical examination showed polygonal, flat, well-defined purple papules, grouped and confluent, on the anterior surface of the wrists, chest, back, and the ventral region of the ankle. The patient also presented nail clubbing, erythema on the anterior surface of the hands, periungueal erythema affecting the matrix, thinning, and longitudinal grooves of the nail surface and pain on palpation of the root of the nails. The primary care physician requested dermatology consultation via the on-line referral service (ALERT®). The dermatologist suggested the diagnosis of lichen planus. The patient began therapy with a topical corticosteroid, which was not helpful. He subsequently started treatment with griseofulvin, 500mg per day, which was effective. Comment: This case report emphasizes the importance of communication between specialists to address the patient’s problems, in order to expedite treatment and improve quality of life.
