Supernumerary nipples and urologic malignancies

Area of Science:

• Urology
• Medical Genetics
• Developmental Biology

Background:

• Minor malformations can sometimes be associated with underlying genetic or developmental abnormalities.
• Urologic malignancies represent a significant health concern, and understanding their etiology is crucial.

Purpose of the Study:

• To investigate the prevalence of specific minor malformations and palmar crease abnormalities in patients with urologic malignancies.
• To compare these prevalence rates with a matched control group.

Main Methods:

• A case-control study was conducted with 203 patients diagnosed with urologic malignancies.
• A control group of 203 individuals with acute infections or cardiopulmonary complaints was matched for age and sex.
• Prevalence of five minor malformations and three palmar/finger crease abnormalities was assessed in both groups.

Main Results:

• A statistically significant higher frequency of supernumerary nipples was observed in patients with urologic tumors (32/203) compared to controls (4/203; p < 0.001).
• Bifid uvula, preauricular pits, and abnormal palmar creases were slightly more common in patients, but these differences did not reach statistical significance.

Conclusions:

• Supernumerary nipples appear to be significantly more prevalent in individuals with urologic malignancies.
• Further research is warranted to explore the potential link between supernumerary nipples and the development of urologic tumors.
