Abstract
Diseases of the breast in adolescent women are usually benign, and their treatment is simple using appropriate medical strategy and rarely surgical therapy. The whole team's real challenge is when the girl presents malignant breast cancer symptoms such as a non-movable tumor, nipple discharge, nipple retraction, retraction of the skin, inflammatory infiltration of the breast, or ulceration. Presented here is a case of a 15-years-old girl with the features of a malignant neoplasm of the breast. There was an observed non-movable tumor, retraction of the nipple, inflammatory infiltration, and pain. The performed ultrasound and magnetic resonance imaging suggested a malignant lesion measuring 84 mm × 66 mm × 50 mm. After many diagnostic difficulties, the lesion evacuated spontaneously, and the abscess was diagnosed. In conclusion, not all features of a malignant breast tumor in adult women are typical for adolescent females. In young girls, breast diseases are usually benign, and appropriate diagnostics and therapy allow for an effective cure. Atypical breast lesions require the extraordinary cooperation of a multidisciplinary team.
