Breast augmentation is considered safe, but rare cases of breast implant-associated squamous cell carcinoma (BIA-SCC) have been reported. This study aimed to systematically review published cases of BIA-SCC, providing valuable clinical data. The review included 14 articles and 18 cases of BIA-SCC. An increasing trend in reported BIA-SCC cases was observed, with four cases in the 1990s and 14 cases since 2010. The mean age of affected patients was 56 years, and symptoms typically appeared around 21 years after breast augmentation. Silicone implants used in cosmetic procedures were most commonly associated with BIA-SCC. Implant removal was necessary in all cases, and some patients required a mastectomy. Treatment approaches varied, with the selective use of chemotherapy and/or radiotherapy. The estimated 6-month mortality rate was 11.1%, while the 12-month mortality rate was 23.8%. The estimated 6-month mortality rate should be cautiously interpreted due to the limited sample size. It appears lower than the rate reported by the American Society of Plastic Surgeons, without clear reasons for this discrepancy. This study highlights the importance of enhanced monitoring and information sharing to improve detection and management of BIA-SCC. Healthcare providers should maintain vigilance during the long-term follow-up of breast augmentation patients.

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. We present an adapted algorithm for working up the undiagnosed inflammatory breast to ensure the timely and accurate diagnosis of IBC. We assert that frank, non-erythematous global skin signs in an enlarged breast with diffuse breast malignancy are sufficient to diagnose IBC if the timing of these signs and findings on biopsy are consistent. We further provide images of atypical IBC identified by global breast skin signs, including peau d\'orange, consistent with IBC in the absence of frank erythema.

BACKGROUND: Inflammatory breast cancer (IBC) is a clinical diagnosis. Here, we examined the association of a \"classic\" triad of clinical signs, swollen involved breast, nipple change, and diffuse skin change, with overall survival (OS).
METHODS: Breast medical photographs from patients enrolled on a prospective IBC registry were scored by two independent reviewers as classic (triad above), not classic, and difficult to assign. Chi-squared test, Fisher\'s exact test, and Wilcoxon rank-sum test were used to assess differences between patient groups. Kaplan-Meier estimates and the log-rank test and Cox proportional hazard regression were used to assess the OS.
RESULTS: We analyzed 245 IBC patients with median age 54 (range 26-81), M0 versus M1 status (157 and 88 patients, respectively). The classic triad was significantly associated with smoking, post-menopausal status, and metastatic disease at presentation (p = 0.002, 0.013, and 0.035, respectively). Ten-year actuarial OS for not classic and difficult to assign were not significantly different and were grouped for further analyses. Ten-year OS was 29.7% among patients with the classic sign triad versus 57.2% for non-classic (p < 0.0001). The multivariate Cox regression model adjusting for clinical staging (p < 0.0001) and TNBC status (<0.0001) demonstrated classic presentation score significantly associated with poorer OS time (HR 2.6, 95% CI 1.7-3.9, p < 0.0001).
CONCLUSIONS: A triad of classic IBC signs independently predicted OS in patients diagnosed with IBC. Further work is warranted to understand the biology related to clinical signs and further extend the understanding of physical examination findings in IBC.

We present a case of left breast abscess in a young male patient who presented with acute onset swelling left breast. Imaging studies helped in accurate diagnosis and the case was managed by subareolar incision and drainage. Subareolar breast abscess is an uncommon entity in male and should be kept as a differential diagnosis for male breast swellings.

Primary breast lymphoma (PBL) of the breast is a rare type of localized non-Hodgkin lymphoma, which is usually of the B-cell. The majority of breast lymphoma present as a unilateral painless breast masses in an older woman, average age at diagnosis 55-60. A less common but distinctive presentation is a young woman of childbearing age who presents during or immediately after pregnancy. We present a 23-year-old postpartum woman with bilateral breast swelling. After surgical drainage and debridement and pathologic examination, the diagnosis of breast Burkitt lymphoma (BL) was confirmed. Chemotherapy was immediately started for her and the patient showed a good response with complete remission.
