Juvenile Papillomatosis in a Young Child: A Case of Infantile Bloody Nipple Discharge.

Background: Bloody nipple discharge (BND) is a rare and distressing finding in infants, although its etiology is usually benign. Diagnostic management of BND and breast lesions in children calls for an adapted approach.

Case: We present the case of an 11-month-old girl with unilateral BND and a painless breast mass.

Tetrasomy and pentasomy of the X chromosome.

Unlabelled: We describe a newborn girl with a life-threatening laryngomalacia and extreme hypotonia. Genetic analysis revealed the very rare genetic condition mosaicism of 48,XXXX and 49,XXXXX (50/50). We here state that the degree of early hypotonia constitutes an important early prognostic feature in this syndrome.
