Abstract
Aims and Background Lipid-rich carcinoma is a very rare variant of breast cancer with an aggressive clinical course and poor prognosis. The present study aimed to explore its clinicopathologic characters. Methods and Study Design We reviewed 3,206 cases treated in two centers in the last 10 years. They all met the criteria of positive oil red O staining, were PAS negative and had the typical histological features included in the study. Their clinical data were collected. The expression of estrogen and progesterone receptors, HER2 and Ki67 was evaluated by immunohistochemistry. Results Forty-nine patients were diagnosed with lipid-rich carcinomas. They were all female and ranged in age from 22 to 72 years (mean, 45). The presenting symptoms included a breast mass or lump and nipple discharge. Axillary lymph node metastases were found in 79.2% of the patients at the time of surgery. Respectively 100% and 89.8% were negative for estrogen and progesterone receptors, whereas 71.4% were positive for HER2. All patients received surgery plus chemotherapy with or without radiotherapy. In vitro MTT assay showed taxol- or platinum-based chemotherapy to be the most effective. The 2- and 5-year overall survival rates were 64.6% and 33.2%, respectively. Conclusions Lipid-rich carcinoma has a biopathological profile significantly different from other types of breast cancer, with a predominance of unfavorable prognostic parameters. Early diagnosis and active treatment may be helpful to increase its overall survival.

Abstract
A 1.5-year-old female, intact, clinically healthy cat presented for a subcutaneous mass of the ventral abdomen. surgical excision and microscopic examination of the mass were performed. Histologically, this was a discrete, unencapsulated, multilobular, expansile mass, which compressed the surrounding normal mammary tissue. Lobules were composed of tubuloacinar structures formed by atypical round to polygonal cells, which contained foamy to microvacuolated cytoplasm and variably sized, intracytoplasmic, distinct vacuoles causing nuclear peripheralization. Neoplastic cells demonstrated intense and diffuse immunoreactivity for cytokeratin and lacked immunoreactivity for vimentin. The vacuolar contents stained positively with oil RedO and negatively with periodic acid-Schiff and Alcian blue stains. Histomorphologic, histochemical, and immunohistochemial analysis support a diagnosis of lipid-rich mammary carcinoma. This is the first report of a cat with a lipid-rich variant of mammary carcinoma.

Abstract
Lipid-rich carcinoma (LRC) of the breast is a rare breast cancer variant that accounts for <1% of all breast malignancies. It has been reported that LRCs are negative for estrogen receptor. Here, we report a case of LRC of the breast that was strongly positive for estrogen receptor and treated with endocrine adjuvant therapy. A 52-year-old postmenopausal female noticed a lump in her right breast by self-examination and presented to our hospital. Physical examination revealed an elastic 30 mm ×20 mm hard mass in the upper medial part of her right breast. The findings obtained using ultrasonography, mammography, and contrast-enhanced magnetic resonance imaging suggested breast cancer. Core needle biopsy resulted in the diagnosis of invasive carcinoma. The patient underwent mastectomy and sentinel lymph node biopsy. Histopathologically, the tumor cells were abundant in foamy cytoplasm. Because the presence of marked cytoplasmic lipid droplets was confirmed by Sudan IV staining and electron microscopic examination of the tumor and the lipid droplets were negative for periodic acid-Schiff staining, the tumor was diagnosed as an LRC. Immunohistochemically, estrogen and progesterone receptors of the tumor were strongly positive, human epidermal growth factor receptor type 2 was negative, and the ratio of Ki-67-positive cells was ~30%. After surgery, the patient underwent combination chemotherapy with anthracycline, cyclophosphamide, and 5-fluorouracil, followed by docetaxel. Thereafter, the pateint was treated with letrozole and has remained well for 24 months with no signs of recurrence.

Abstract
Lipid-rich carcinoma of the breast is extremely rare with no standard guidelines for treatment with poor patient prognosis. In the present study, the clinical features, imaging results, pathology, immunohistochemistry, treatment and prognoses of two patients with lipid-rich carcinoma of the breast were analyzed. Two patients were admitted to the Yantai Yuhuangding Hospital Affiliated to the Medical College of Qingdao University (Yantai, Shandong, China) for examination of a palpable mass in the breast. Enlarged lymph nodes were found in the axilla of each patient. The results of mammography and echography imaging suggested the presence of malignancy. A modified radical mastectomy was performed in each patient, and pathological examination revealed atypical large vacuolated cells arranged in clusters and confirmed lipid-rich carcinoma and lymph node metastases. The tumor tissue of patient one was immunohistochemically positive for estrogen receptor (ER), p53, p120 and E-cadherin, and negative for progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2), with a Ki-67 labeling index of 50%. The tumor tissue of patient two was immunohistochemically positive for p53, and negative for ER, PR, HER-2 and cytokeratin 5/6, with a Ki-67 labeling index of 30%. Post-surgery, patient one was administered chemotherapy for six cycles, radiotherapy and endocrine therapy in the form of anastrozole. Patient two was administered three cycles of chemotherapy without radiotherapy. Subsequent to being followed up for 25 months and 13 months, respectively, there was no evidence of recurrence or distant metastasis in patient one or two, respectively.

Abstract
A 56-year-old woman noticed a palpable mass in her left breast during self-examination. Patient was admitted to our hospital and malignant bifocal tumour was diagnosed by ultrasonography, digital mammography, magnetic resonance, and core-cut biopsy. The patient underwent planned conservative surgery (biquadrantectomy) with a sentinel node examination, but after results of the frozen section with positive resection margins and positive sentinel lymph nodes subsequent mastectomy with axillary lymph node dissection were realized. Histology in the resection specimen revealed two isolated and distinct tumours. One of the lesions represented conventional invasive ductal carcinoma of histological grade 3, and the second tumour was evaluated as invasive lipid-rich carcinoma, containing tumour cells with clear and foamy cytoplasm. Lipids in neoplastic cells were detected by Oil Red O staining and ultrastructural examination. Immunohistochemical analysis of both carcinomas was almost identical with negative steroid receptors, positive staining of HER-2, and p53 and with high proliferation activity (Ki-67). Mastectomy specimen contained residual foci of invasive ductal carcinoma and dissected axillary lymph nodes were free of metastasis. Patient underwent first cycles of chemotherapy with paclitaxel and Herceptin together with local radiotherapy and two month after surgery is without any evidence of the disease.

Abstract
We report a rare case of intraductal lipid-rich carcinoma of the breast with a component of glycogen-rich carcinoma. An impalpable tumor that was revealed by mammography and magnetic resonance imaging was excised. Histologic examination showed vacuolated neoplastic cells in the mammary ducts, and electron microscopy confirmed lipid droplets in the cytoplasm. The coexistence of glycogen-rich carcinoma was shown. Lipid-rich carcinoma that is coexistent with glycogen-rich carcinoma is rare, and most lipid-rich carcinomas are invasive. Intraductal lipid-rich carcinoma is difficult to detect without echography or mammography.

Abstract
Sebaceous metaplasia in canine mammary tumors is a rare condition with only 1 case documented. The current study describes a case of sebaceous metaplasia in a mammary gland carcinoma of an 8-year-old intact, nulliparous female Poodle dog with a subcutaneous tumor located in the left fifth mammary gland. The lesion measured 0.7 cm × 0.5 cm × 0.6 cm in diameter, was firm, circumscribed, painless, non-haired, and non-ulcerated, and did not adhere to deep tissues. The cut surface was non-lobulated, non-encapsulated, whitish to gray, and opaque. Histological evaluation revealed 3 different populations of cells: the first was composed of columnar to cuboidal malignant epithelial cells arranged in intraductal papillary projections, the second of myoepithelial cells associated with a myxoid stroma, and the third presenting sebaceous metaplasia similar to those previously described in both human and veterinary medicine.

Abstract
Lipid-rich carcinoma of the breast is a rare variant of breast cancer, accounted for <1% of all breast malignant tumors. We retrospectively analyzed the clinicopathologic characteristics of lipid-rich carcinomas of the breast. A panel of estrogen receptor, progesterone receptor, human epidermal growth factor receptor-2 (HER-2), cytokeratin (CK) 5/6, CK14, and P63 was prepared for detection of lipid-rich carcinoma. Fluorescence in situ hybridization and electron microscope assays were performed for detecting HER-2 gene amplification and ultrastructure. Survival analysis were carried out using Kaplan-Meier and Cox regression methods. Receiver operating characteristic test was also performed. Estrogen receptor, CK5/6, CK14, and P63 were negative. Progesterone receptor (1/17) and HER-2 (17/17) were positive. HER-2 gene amplification was detected in all included cases (ratio values >2.2). Ultrastructure showed fat droplet and electron-dense material in the cytoplasm. Statistical differences were detected among survival and age (P = .033), histologic grade (P = .004), lymph node involvement (P = .001), and HER-2 expression (P = .002), respectively, using Kaplan-Meier methods. Statistical differences were also detected (P = .017) using Cox regression methods. Receiver operating characteristic test displayed significant statistical differences; the prognosis had a correlation between HER-2 expression "+" and HER-2 expression "++" (P = .004). Lipid-rich carcinoma of the breast was an HER-2 overexpressing subtype of the breast carcinoma. Survival of lipid-rich carcinoma might be associated with age, histologic grade, lymph node involvement, and HER-2. The HER-2 expression, however, might play an important role in predicting the prognosis of lipid-rich carcinoma of the breast.

Abstract
This article reviews cytomorphology of rare malignant tumors of the breast: squamous carcinoma, metaplastic carcinoma, adenoid cystic carcinoma, apocrine carcinoma, secretory carcinoma, lipid-rich carcinoma, and carcinoma with choriocarcinomatous features. It is important to bear in mind the cytomorphology and diagnosis of rare malignant tumors of the breast in analysis of breast fine needle aspiration smears. Although rare, these malignant tumors can be diagnosed by the cytomorphological characteristics, and should be included in the differential diagnoses of breast neoplasms.

Abstract
Clinicopathological and immunohistochemical findings of two uncommon canine lipid-rich mammary carcinomas are described. The predominant histological feature in both tumours was the presence of at least 80% of cells with intracytoplasmic vacuoles which stained positively with Sudan IV but not with alcian-blue periodic acid-schiff method. In both tumours, small groups of non-vacuolated cells were identified among the vacuolated cells. However, histological and immunohistochemical differences were also found between these tumours. Thus, one of them was composed of tumour cells with a large and single vacuole, which were arranged in lobular pattern, while the other neoplasm showed an intraductal growth of tumour cells with a fine vacuolated cytoplasm. Immunohistochemically, in the first tumour most vacuolated cells were positive for CK (cytokeratin)8-7, indicating a secretory epithelial immunophenotype while CK5 and CK8-7-expressing non-vacuolated cells were associated with luminal duct immunophenotype. However, in the second tumour the expression of CK14 in most of vacuolated cells and alpha-smooth muscle actin (alpha-SMA) in non-vacuolated cells, alone or in combination with CK5 suggested a myoepithelial immunophenotype for both cell types. These results suggest heterogeneity of the cell type and growth pattern for this type of canine tumour as has been described in women but not in dogs.

Abstract
AIMS To investigate whether alterations of the HER2 gene occur more frequently in histologically unfavourable subtypes of invasive breast cancer. METHODS The study was composed of nine invasive apocrine, six lipid-rich, 12 glycogen-rich, 11 micropapillary and 33 pleomorphic lobular breast carcinomas. Lymph node involvement was represented in all subgroups. HER2 status was confirmed in all cases by using immunohistochemistry (CB11, Herceptest) and fluorescent in-situ hybridization (FISH) analysis (Vysis). RESULTS Micropapillary and apocrine carcinomas showed the highest rate of protein overexpression (72% and 66%) and gene amplification (45% and 44%). Protein overexpression was common in poorly differentiated pleomorphic lobular carcinomas (56%); however, this subgroup failed to show an increased number of gene copies by FISH (31%). The incidence of HER2 overexpression (33% and 50%, respectively) and gene amplification (25% and 33%, respectively) among glycogen-rich and lipid-rich carcinomas was not higher than that observed in breast cancer generally. CONCLUSION Our data suggest that preferential involvement of the HER2 gene in micropapillary and apocrine breast carcinomas may contribute to their aggressive behaviour.

Abstract
We report on a rare distinctive variant of infiltrating ductal carcinoma characterized by sebaceous differentiation of tumor cells. The neoplasm was identified in a lumpectomy specimen from a 45-year-old woman with extensive metastatic disease. In addition to conventional in situ and invasive ductal components, approximately half of the tumor cells exhibited a phenotype resembling tumors of the sebaceous skin appendage with coarsely vacuolated cytoplasm and peripherally displaced nuclei. The sebaceous moiety was also present in the distant metastatic deposits. There was no evidence of mucin production by tumor cells. Ultrastructurally, empty-appearing non-membrane bound vacuoles attested to the sebaceous cells' lipid content. The immunoprofile of the lesion included positivity for cytokeratin and epithelial membrane antigen. Vimentin, S100 protein and carcinoembryonic antigen were not expressed. Most tumor cell nuclei reacted with antibodies to oestrogen and progesterone receptors but failed to show overexpression of the HER2/neu protein. The MIB-1 labeling index averaged 16%. At variance with sebaceous breast carcinomas on record, the present case is notable for its prolonged clinical course.
