Abstract：
Metastasis from non-mammary malignant neoplasms to the breast is rare and represents 0.2%-1.3% of all breast malignancies. Fine needle aspiration cytology (FNAC) is the first line of investigation for any breast lump and cyto-morphological appearance of primary breast malignancies is well documented. Occasionally metastasis to the breast may be the initial presentation and can masquerade clinically as primary breast malignancy. The present case describes the clinical and cytological challenges in an unusual case of ovarian carcinoma with initial presentation as breast mass, mimicking as inflammatory carcinoma. In cytology the breast lesion was initially misdiagnosed as primary breast carcinoma and subsequently diagnosed as metastatic ovarian carcinoma based on core needle biopsy findings, aberrant immuno-profile and clinical findings; thus making the complex case worthy of discussion.
摘要：
从非乳腺恶性肿瘤到乳腺的转移很少见，占所有乳腺恶性肿瘤的0.2％-1.3％。细针抽吸细胞学（FNAC）是任何乳腺肿块的第一线研究，并且有充分的文献记载了原发性乳腺恶性肿瘤的细胞形态学外观。偶尔转移到乳房可能是最初的表现，并且可以在临床上伪装成原发性乳腺恶性肿瘤。本病例描述了一个不寻常的卵巢癌病例的临床和细胞学挑战，最初表现为乳腺肿块，模仿炎症性癌。在细胞学检查中，乳腺病变最初被误诊为原发性乳腺癌，随后根据芯针活检结果诊断为转移性卵巢癌。异常的免疫特征和临床发现；因此，这个复杂的病例值得讨论。
