Calcifying fibrous pseudotumor is a rare lesion of uncertain histogenesis that has a unique histologic appearance. We report herein a case of a 24-year-old woman with a mass on the right posterior side of the neck. Magnetic resonance imaging with contrast showed a well-circumscribed mass between the right splenius and semispinalis cervicis muscles; the study suggested high collagen content. Simple excision was performed. The histologic findings were diagnostic of calcifying fibrous pseudotumor. Our review of 19 previously reported cases suggests that a good outcome is expected when a diagnosis of calcifying fibrous pseudotumor is made.
