Scrotal Hair in Infancy: Outcome Verification of an Isolated Condition Needing Minimal Assessment

Rarely, infant boys present with a few, pigmented scrotal hairs and often laboratory assessment is done. This report aims to ascertain any possible pathology of this condition by providing outcome data for 8 patients. This report reviews the clinical history of eight male infants, who initially presented with scrotal hair growth without other signs of virilization. Follow-up documented no progression or recurrence or evidence of androgen excess among 4 of the 8 patients beyond infancy and 4 patients beyond the age of puberty. Only one did not show regression of pubic hair during infancy, but persistence to age 7 when hormone levels were shown to be normal. Hence, these data, plus a summary of the published literature that confirms that this finding, without other evidence of androgen excess, is benign and self-limited and does not require laboratory assessment, but only clinical follow-up.
