Fennell J, Garcia P. Bilateral pseudomamma [published online June 8, 2018]. Consultant for Pediatricians.
During a routine well-child visit, the parents of a 2-month-old girl pointed out “lumps” near the child’s axillae. The infant was the product of a full-term gestation and had been growing and developing normally.
Physical examination. On the lateral aspect of each pectoralis major, the child had 1-cm flat circular areas of hyperpigmentation. The lesions were located superolateral to the areolae and were symmetric in position. Further examination confirmed that each lesion had a central protuberance, but no underlying tissue was palpated (Figures 1-3).
Based on the physical examination findings, the patient received a clinical diagnosis of polymastia (pseudomamma) in the axillary line.
