Rhabdomyomatous mesenchymal hamartoma.
We present the fifth case of rhabdomyomatous mesenchymal hamartoma, the first reported in a female infant. The patient is an otherwise healthy 3-day-old Latin American infant, the product of an uneventful pregnancy and term delivery by a primigravida 23-year-old. Otolaryngic consultation was obtained when a 4-mm polypoid mass was noted within the left naris. Histopathology revealed the characteristic central core of mature skeletal muscle with extension peripherally into the glandular and follicular dermal structures. Although primarily of cosmetic significance, a possible association with other anomalies has been reported.
