Away from the milky way: An extremely rare case of pulmonary ectopic breast

Ectopic breast is defined as the presence of breast tissue outside the pectoral region. In this article, we are reporting
an extremely rare case of pulmonary aberrant breast tissue. A 79‑years‑old Caucasian woman with the history of
hypertension, diabetes mellitus and ischemic heart disease, presented to the emergency department for worsening
dyspnea on exertion and pleuritic chest pain over the last few days. Both thoracic CT scan and the gross evaluation of
tumor after its removal by thoracotomy were in favor of a soft tissue tumor such as pulmonary lipoma, whilst surprisingly
the histological examinations revealed the mass to be ectopic breast tissue. Although it is extremely rare, this diagnosis
should be considered in the evaluation of pulmonary masses
