Breast malignancies encompass various subtypes which differ in their clinical presentations, outcomes, and response to the treatment regimens. Thus, a proper histological diagnosis and a special mention of the rare histologic subtypes are required to formulate clear recommendations of their treatment protocols.
This is a 1-year retrospective study highlighting the rarely encountered subtypes on the mastectomy specimens received.
We encountered only 11 rare cases out of the total 153 mastectomy specimens received. The rare subtypes were as follows mucinous cystadenocarcinoma (0.6%), mucinous carcinoma (0.6%), dermatofibrosarcoma protuberans (0.6%), Squamous cell carcinoma (0.6%), papillary carcinoma (2.6%), medullary carcinoma (0.6%), and malignant mesenchymal tumor (1.3%).
Our data suggest that these variants are distinct clinicopathological entities with a unique hormonal receptor status. Scant information is available on the rare breast tumor subtypes.
乳腺恶性肿瘤包含多种亚型，它们在临床表现、预后以及对治疗方案的反应方面存在差异。因此，需要进行恰当的组织学诊断，并特别提及罕见的组织学亚型，以便制定明确的治疗方案建议。
这是一项为期1年的回顾性研究，重点关注所接收的乳房切除标本中罕见的亚型。
在总共153份接收的乳房切除标本中，我们仅遇到11例罕见病例。罕见亚型如下：黏液性囊腺癌（0.6%）、黏液癌（0.6%）、隆突性皮肤纤维肉瘤（0.6%）、鳞状细胞癌（0.6%）、乳头状癌（2.6%）、髓样癌（0.6%）和恶性间叶性肿瘤（1.3%）。
我们的数据表明，这些变体是具有独特激素受体状态的不同临床病理实体。关于罕见乳腺肿瘤亚型的信息很少。
