RESUMO

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.

RESUMO

INTRODUCTION: Giant juvenile fibroadenomas represent only the 0.5% of all fibroadenomas, constituting a rare condition in adolescence. In prepuberty, the presence of this condition is extremely rare. PRESENTATION OF CASE: We describe a rare case of a 12- year-old Caucasian girl who presented to our Hospital complaining of a palpable mass with rapid enlargement in her right breast that she had first noticed 3 months ago. Her menarche hadn't occurred yet. DISCUSSION: Physical examination showed a giant mass of 15 × 13 cm in the right breast. The patient was further evaluated via ultrasonography showing a sole large lesion of 13 × 12 cm in the right breast. A surgical procedure under general anesthesia was performed. Histopathological findings after the surgical excision were suggestive of giant juvenile fibroadenoma. The patient has a normal breast development over a period of 9 month follow up. CONCLUSION: Giant juvenile fibroadenomas should be included in differential diagnosis of a breast mass in prepubertal girls despite the fact that they are very rare in prepuberty, tend to appear later during adolescence and their prevalence is lower in Caucasians. The remarkable size and the rapid growth of the lesion should not be ruled out in the diagnostic process of an adolescent breast.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
