Of the many forms of supernumerary breast tissue, the most common form
is the isolated presence of an accessory nipple, polythelia, While fa
milial polythelia is recognized, it is extremely rare. In the past sev
eral years, polythelia has been noted to be associated with nephrourol
ogical anomalies. All reports of such a relationship are in random, no
nfamilial cases of polythelia, We report three cases of polythelia in
a family over two generations who had no urinary tract abnormalities,
Discussion includes a comprehensive review of familiar polythelia and
its association with renal anomalies, From this review, the associatio
n of familiar polythelia with nephrourological abnormalities will be d
elineated, Although in this report of a single family with polythelia
we did not demonstrate any renal anomalies, we feel that a thorough ph
ysical exam, urine analysis, and renal ultrasound should be pursued in
any patient with a significant familial history of polythelia.
