[Granuloma faciale: efficacy of cryosurgery in 2 cases].
BACKGROUND: Granuloma faciale is a rare condition of unknown pathogenesis. Treatment often gives less than satisfactory results. We report two cases successfully treated with cryosurgery. CASE REPORT: A 42-year-old woman had a round 65 x 40 mm erythematous violet-colored papulous plaque on the right cheek. Histology reported a dense inflammatory infiltration of the superficial and mid derma around dilated vessels under a normal epidermis. The infiltration was composed of histiocytes, lymphocytes, plasma cells, neutrophils and eosinophils and was compatible with granuloma facial. Surgical treatment was performed but was followed by recurrence within a few months. Class I local steroids, cotton swab cryotherapy and oral dapsone remained ineffective. Cryosurgery however led to cure without recurrence at 1 year follow-up. The second patient was a 52-year old man with an oval reddish-brown papulous plaque on the right preauricular area. The plaque measured 40 mm in diameter and histology favored granuloma facial. Three cotton swab cryotherapy sessions and one surgical excision procedure were followed by recurrence. Cryosurgery provided successful cure without recurrence at 3.5 years follow-up. DISCUSSION: Most destructive treatments for granuloma facial, including pulverization cryotherapy, surgery, and CO(2) or argon laser are unsuccessful in preventing recurrence. Cryosurgery was proposed in 1977 but few cases have been reported since. Medical treatments have been variously successful with most authors reporting unsatisfactory results. In our two cases, surgical excision was rapidly followed by recurrence and in one case dapsone was ineffective. Cryosurgery provided rapid regression of the lesion and recurrence-free cure at 1 and 3.5 years follow-up respectively. Cryosurgery is an effective treatment for readily recurrent eosinophilic granuloma facial and should be proposed as first intention therapy.
