Rhabdomyomatous mesenchymal hamartoma is an extremely rare congenital lesion, and very few cases have been reported even though its macroscopic and microscopic features make diagnosis easy. An 18-year-old woman consulted with a pedunculated mass in the medial region of her neck. The mass was surgically removed, and rhabdomyomatous mesenchymal hamartoma was diagnosed. The clinical, macroscopic, histologic, and immunochemical characteristics that allow diagnosis of this entity are discussed. Although association with congenital abnormalities is uncommon, this possibility should be assessed by the clinician.

ABSTRACT: Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare congenital lesion of the dermis and subdermis. It has been described predominantly in newborns, with 30 cases reported in the English literature. Typically, it appears as a skin tag, papule, nodule or a mass involving the face or sternal notch. A 28-day-old girl presented with a 1.4 x 0.8 cm soft skin tag in the right sternoclavicular area. Physical examination revealed no congenital anomalies. A shaved biopsy showed that the core of the lesion contained striated muscle fibers mixed with hair follicles and sebaceous and eccrine glands. Thin epidermis lined the outside of the tag. We report a patient with a RMH in a site not previously reported and discuss the differential diagnosis.Pathology & Oncology Research 02/2007; 13(4):375-8. DOI:10.1007/BF02940320 · 1.86 Impact Factor
