title: [Merkel cell carcinoma. Utility of scintigraphy with 111In-DTPA-pentetreotide].
abstract: Merkel cell carcinoma (MCC) is an unusual malignant primary skin tumor, having a high incidence of local recurrent, and regional and distant metastasis. Due to its capacity to express somatostatin receptors, it can be detected in vivo with 111In-pentetreotide scintigraphy (Ostreoscan). We present a case of a MCC whose scintigraphy revealed regional metastases of a primary frontal cutaneous tumor that had been removed previously. The results verified a good correlation with clinical, radiological an histopathological findings.
