Abstract and Introduction
Abstract
Objective: The purpose of this narrative review is to summarize the contributors to misdiagnosis or delayed diagnosis of inflammatory breast cancer (IBC) and strategies for expedient diagnosis.
Background: Patients with IBC often report the disease as initially being misdiagnosed, most commonly as mastitis.
Methods: We reviewed the literature on this challenging diagnosis by using sequential PubMed search criteria including IBC breast symptoms, IBC diagnosis, and IBC imaging modalities to augment the authors' knowledge of IBC. Other references were added from the manuscripts identified in the PubMed searches and from manuscript reviewers.
Conclusions:Several factors contribute to the delayed diagnosis of IBC. One important factor is that IBC is uncommon, and many generalists may not be aware of it in the differential diagnosis of breast skin symptoms. Several features of IBC contribute to the low sensitivity of mammography for its detection, and so the diagnosis is based on clinical factors and is thereby subjective. The presentation can be highly varied; classic textbook images that do not capture the range of presenting signs and symptoms across skin tones may contribute to missed diagnoses in patients with atypical presentations. In fact, the staging system of the American Joint Committee on Cancer, which requires erythema of the breast skin for diagnosis, may exclude patients with obvious global breast skin findings that are not explicitly red.
