Synopsis

A cutaneous myxoma is a benign dermal tumor that is typically associated with Carney complex (CNC), which is also known as LAMB (lentigines, atrial myxoma, blue nevi) syndrome or NAME (nevi, atrial myxoma, myxoid neurofibromas, ephelides) syndrome. Although more commonly noted to occur as part of CNC, sporadic cutaneous myxomas have been reported.

Cutaneous myxomas typically present as small (< 1 cm) dermal or subcutaneous nodules located on the head, neck, or trunk. Lesions often present by early adulthood and have a tendency to recur following removal. When associated with CNC, additional notable findings include lentigines, blue nevi, cardiac myxomas, and various endocrine and nonendocrine tumors.
