Squamous Cell Carcinoma of the Breast Diagnosis by Vacuum-assisted Core Biopsy

Abstract

Squamous cell breast carcinoma is a rare occurrence. Often the tumor is metastatic from an extramammary primary tumor. In order to determine the nature of the lesion, extensive sampling is necessary. We report a case of primary squamous cell carcinoma of the breast diagnosed by vacuum-assisted core biopsy.

Systematic Review of Postradiotherapy Bronchiolitis Obliterans Organizing Pneumonia in Women With Breast Cancer

“…Diagnostic and treatment data (Table 6) show that 10 patients were hospitalized [13,14,28,33,[36][37][38][39]46]. BOOP occurred in the contralateral lung in 22 patients, mostly during initial diagnosis, although in some, the contralateral lung was involved only at relapse [43].…”

“…Relapses were usually treated with steroids, although one patient was treated successfully with clarithromycin because of the patient's inability to tolerate steroids [31]. Total duration of steroid use for patients who relapsed often exceeded 1 year, with several patients still receiving steroid therapy by the time of study publication [14,37,41,48]. Among the eight patients who were not treated with corticosteroids, BOOP resolved spontaneously in four [28, 30,45,49], after trastuzumab was discontinued in two [33,44], after macrolide therapy in one [30], and after nodule resection in one [30]; the remaining case report had no treatment information [42].…”

Immunohistochemical Characterization of Mammary Squamous Cell Carcinoma of the Dog

“…11 In the dog, it is also important to differentiate squamous neoplasms originating from the mammary parenchyma from those derived from the skin or cutaneous adnexa. The morphology of these 2 tumors is similar, 17 but the prognosis is worse for mammary tumors.…”

Metaplastic squamous cell carcinoma of the breast: A case report and literature review

“…2 Another theory defended by Stevenson et al is that the lesion is a disease with varying degrees of squamous metaplasia, representing an extreme form of squamous metaplasia inside the adenocarcinoma. 3 Squamous cell carcinoma of the breast is an extremely rare type, representing less than 1% of all invasive breast carcinomas with a mean age for onset among women of 54 years. 2 When found in the breast, other sites of extra mammary lesions should be sought, since there is a possibility that this is a metastatic tumor and not a primary lesion.…”

“…For this reason, the nature or origin of the lesion needs to be determined. 3 The objective of our study is to report a case of metaplastic carcinoma, squamous subtype, diagnosed by core needle biopsy.…”
