RESUMEN
INTRODUCTION: Lobular breast carcinoma includes lobular carcinoma in situ (LCIS) and invasive lobular carcinoma (ILC). The association of LCIS with total metastatic lobular breast cancer is very rare. PRESENTATION OF CASE: We present a case of a totally metastatic lobular breast cancer in an asymptomatic 64-year-old postmenopausal woman, with no suspicious microcalcifications in mammography. A total hysterectomy with bilateral salpingo-oophorectomy, pelvic lymphadenectomy, infracolic omentectomy and appendectomy was performed along with a quadrantectomy of the upper outer quadrant of left breast, and systematic isolateral lymphadenectomy of the left axilla. DISCUSSION: LCIS is usually undetectable because it isn't associated with clinical abnormalities in clinical examination and is presented in mammography as microcalcifications or focal asymmetric densities. ILC histopathologic features are responsible for the high false-negative rates on mammography, leading to moderate detection sensitivity. CONCLUSION: Our case is a very rare condition. No 'similar' case have been described in the literature so far.
RESUMEN
A 12-year-old girl was referred to our radiology department with a rapidly enlarging mass in the right breast. Fine-needle aspiration cytology was suggestive of fibroadenoma. Total excision of the mass was done, and diagnosis was confirmed by histopathology.

Dual-energy contrast-enhanced spectral mammography (CESM) represents a relatively new diagnostic tool adjunct to mammography. The aim of this study was to strengthen the breast imaging-reporting and data system (BIRADS) classification score in order to improve early breast cancer diagnosis. For this reason, we propose a sum score, termed malignancy potential score (MPS), incorporating the standard BIRADS score and our proposed CESM score. From September 2014 to September 2015, 216 females (age range, 26-85 years; mean age 54.6 years) underwent CESM evaluation of mammographic findings that were primarily assessed as BIRADS 2-5. 10 of these patients had bilateral findings; a total of 226 lesions were examined. High-energy image evaluation was based on the intensity of contrast enhancement of the lesion compared with background enhancement, categorized as Type -1, 0, 1 or 2 enhancement. Histopathology reports were compared with imaging assessment. 98 of 226 lesions were malignant and 128 of 226 lesions were benign. The area under the curve was 0.843, 0.888 and 0.917 for mammographic BIRADS score, CESM score and MPS, respectively, with p-value < 0.05. The sensitivity, specificity and accuracy rates were 91.83, 80.47 and 85.40%, respectively, when a best MPS cut-off point of 4 was used. The malignancy potential score (MPS) has higher diagnostic performance than digital mammography or CESM alone. MPS empowers the credibility of the digital mammography BIRADS score and our proposed type of enhancement in dual-energy CESM and is a diagnostic tool that increases the accuracy rate in early breast cancer diagnosis.

In recent years, the use of elastography in addition to sonography has become a routine clinical tool for the characterization of breast masses. Studies have investigated the improvement of specificity in differentiating benign from malignant breast masses. Therefore, additional use of elastography could help reduce the number of unnecessary biopsies in benign breast lesions especially in category IV lesions of the ultrasound breast imaging reporting data system. Ultrasound elastography is a cheap, readily available, useful, quick, noninvasive method, but it needs specific training as well as acknowledging technical and pathological factors, which may influence it. Both strain and acoustic radiation force impulse (ARFI) methods have been evaluated in breast lesions. Whereas strain elastography results in qualitative imaging of tissue stiffness due to induced compression, ARFI elastography displays quantitative and qualitative information of tissue displacement. A standardized imaging protocol is essential for an adequate and effective examination, also helping reduce the dependence from operators. Furthermore, knowledge of pitfalls that can be encountered when ultrasound elastography is performed may help avoid erroneous image interpretation. In this article, we describe a practical examination protocol for both strain and ARFI elastography and demonstrate the elastographic imaging findings in benign and malignant breast lesions. Short video clips displaying the technique are included as supplementary material.

Breast adenomyoepithelioma is considered as an uncommon breast tumor. It is evaluated as a variant of intraductal papilloma. The treatment of choice is local resection with free margins. It is the first case of breast adenomyoepithelioma reported with conventional ultrasonography, elastography (both free-hand and acoustic radiation force impulse imaging), digital mammography, contrast-enhanced digital mammography, and pathology findings. A 35-year-old white woman presented with a painless lump of the left breast. Treatment was local resection with free margins. There has been no recurrence for 6 months. Although breast adenomyoepithelioma is an uncommon breast tumor, its awareness is imperative because the differential diagnosis from other breast tumors is quite extensive.

Lymphomas constitute approximately 0.15% of malignant mammary neoplasms. Less than 0.5% of all malignant lymphomas involve the breast primarily. Primary non-Hodgkin breast lymphoma is usually right sided. The combined therapy approach, with chemotherapy and radiotherapy, is the most successful treatment. Mastectomy offers no benefit in the treatment of primary non-Hodgkin breast lymphoma. To the author's knowledge, this is the first published case of primary non-Hodgkin breast lymphoma reported with conventional ultrasonography, elastography (both freehand and acoustic radiation force impulse imaging), digital mammography, contrast-enhanced digital mammography, and pathology findings. A 45-year-old woman presented with a lump in the right breast for 2 months. There was no evidence of systemic lymphoma or leukemia when the breast lesion was detected. Imaging findings were negative for lymphoma. Ipsilateral lymph nodes were not palpable. The mass was resected, and histopathology findings were diagnostic of non-Hodgkin lymphoma. Immunohistochemistry was confirmatory of non-Hodgkin lymphoma, diffuse large cell type of B-cell lineage. Although primary and secondary lymphomas of the breast are rare entities, they should be considered in the differential diagnosis of breast malignancies.

Lower extremity's venous pathology was traditionally investigated by intravenous venography. Nowadays Color Doppler flow imaging is widely accepted as a well established, noninvasive method for the evaluation of deep pelvic and lower extremity's venous system. The vast majority of authors conclude that the method can safely replace diagnostic venography in all patients with venous thrombosis, thrombophlebitis and valve or communicating veins insuffciency. Optimal performance of Color Doppler flow imaging as a diagnostic tool for the whole lower limb veins requires: Proper equipment specifications and settings. Knowledge of regional venous anatomy. Established examination protocols. Evaluation of morphological and functional findings. Documentation of the findings. All these steps are described as a sequence of guidelines, photographs and multiple ultrasonographic images. Our paper can be useful to all physicians or sonographers involved with color Doppler studies for the evaluation of lower limb venous diseases and abnormalities.

BACKGROUND: Breast fibromatosis is a rare, benign, recurring, locally destructive entity. CASE: A 35-year-old woman underwent right-sided lumpectomy, revealing fibromatosis with epithelial hyperplasia. Two years later, she was re-evaluated due to a three times as large mass recurrence on X-ray mammography. (99m)Tc-(V)DMSA scintimammography revealed diffuse increased radiotracer uptake occupying the entire breast. A less widespread similar uptake was observed in the contralateral breast. Mammography did identify neither the posterior margins of the mass nor the left-sided lesion. The patient underwent mastectomy and left-sided open biopsy, revealing bilateral fibromatosis. Ki-67 expression was moderate. CONCLUSIONS: (99m)Tc-(V)DMSA scintimammography can provide information regarding the nature of the lesion, its extent and bilateral involvement (especially in dense breasts) and could prove useful as a predictor of its potential for recurrence.
