Objectives Squamous cell carcinoma (SCC) of the breast is rare, accounting for less than 0.1% of all breast cancers. Our purpose is to report the clinicopathological features of this disease.
Methods We report eight cases of primary SCC of the breast treated at Salah Azaiez Institute between 2005 and 2019.
Results The median age of our patients was 58 years old (IQR 44–75 years). The Chief complaint was Lump discovery during self-palpation. The median tumor size was 73.5mm (IQR 25–120mm). The disease stage was as follow: T4b in four cases, T2 in 3 and T3 for the last case. The surgical treatment was radical in half of the cases and conservative for the other half. Three patients had positive lymph nodes. Locoregional radiotherapy was performed in 5 cases. Four patients received Six cycles of standard breast chemotherapy each. The median follow-up was 21.5months. Five patients presented a locoregional relapse after an average of 8.8 months (IQR2–22 months). Distant relapses were encountered in 4 cases after an average of 20 months (IQR 3–46 months). The site of metastasis was liver and lung in 2 patients, brain in one patient and contralateral axillary node in the other one. Three women are still in remission, three had a progressive disease and the other two died.
Conclusions SCC is an aggressive entity, associated with a poor prognosis. The standard treatment is surgery. The place of adjuvant treatment remains debatable. Meta-analysis are warranted to for a better selection of prognostic factors and shaping the ideal course of treatment.
