A case of Maffucci's syndrome associated with primary hyperparathyroidism.

Maffucci's syndrome (association of multiple enchondromatosis and multiple hemangiomata) is rarely associated with other ectodermal tumors. The present case is the second in literature in which the Maffucci's syndrome is associated with the parathyroid adenoma resulting in primary hyperparathyroidism. Although the cystic lesions of the bone and the ectopic calcifications are common to both diseases, pathogenesis apparently not related. The association of parathyroid adenoma with Maffucci's syndrome suggests the potential involvement of mesenchymal organs in this ectodermal neoplastic disorder.
