Two cases of non-syndromic congenital unilateral breast hypoplasia in one family

Abstract

Micromastia or breast hypoplasia is described as underdevelopment of a woman’s mammary tissue. We present the case of a 15-year-old girl with unilateral micromastia, with familial predisposition. Ultrasound, hormonal, dysmorphic, cardiologic, genetic examinations and testing were performed. No mutation in the whole- exome sequencing was found, nor novel mutation. Some of these cases have been reported to be related to breаst cancer so further follow-up is mandatory. Therapy consists of surgical reconstruction of the affected breast. This is a rare condition and it requires a multidisciplinary approach.
