Bloody nipple discharge in Carney complex: A case report.

Carney complex (CNC) is an extremely rare, autosomal dominant genetic syndrome consisting of pigmented skin and mucosal changes with multiple endocrine and nonendocrine tumors, including the breast. Breast tumors are typically multiple and benign and are most commonly reported as myxoid fibroadenomas and/or intraductal papillomas. We present a young female patient with known CNC who presented with copious bloody nipple discharge with multiple breast lumps and discuss the breast imaging features regarding this complex and often underrecognized genetic condition.

Radiological and pathological correlation of a rare case of primary breast follicular lymphoma in a male patient, presenting as gynaecomastia.

We present an exceptionally rare case of primary breast follicular lymphoma in a male patient, who presented to us with gynaecomastia for investigation. To our knowledge there have only been two other cases published in the literature to date. In Western Australia, there have been no cases in at least the past 10 years. This particular case highlights the importance of radiological and pathological correlation in making the diagnosis, particularly in the assessment of breast lumps in a male patient, where imaging and clinical findings alone could not make the diagnosis.

An atypically located pleomorphic adenoma: Radiological and pathological correlation.

Pleomorphic adenoma is a common benign salivary gland neoplasm which very rarely occurs in the breast. Its radiologic and pathologic appearance may be mistaken for other benign or malignant lesions such as a fibroadenoma or invasive ductal carcinoma. Due to the risk of local recurrence and, rarely, malignant transformation, wide local excision with clear margins is recommended. As such, a correct diagnosis of this lesion is important to ensure appropriate surgical treatment. We report a case of an atypically located pleomorphic adenoma with radiologic-pathologic correlation in an asymptomatic 63-year-old woman.

Population screening detected non-lymphomatous non-mammary metastases to the breast. A radiology multimodality pictorial essay.

This pictorial essay is a presentation of imaging appearances of non-mammary cancer metastases to the breast detected in asymptomatic women attending BreastScreen Western Australia (BSWA) from 2005 to 2019. Haematological malignancies were excluded. Thirteen cases of histologically proven extramammary metastases to breast were identified from the BSWA data base. Five cases were ovarian cancer metastases, 3 melanoma metastases, 2 of adenocarcinoma metastases with foregut primary and one each of endometrial, renal and carcinoid metastases. Metastasis to breast commonly presented as circumscribed masses (N = 12) at mammography and as hypoechoic masses (N = 10) at ultrasound with a predilection to upper outer quadrant of breast. Metastases to breast from non-mammary primary while a rare occurrence in a breast screening program, may be the first clinical presentation of malignancy in asymptomatic women.

Positive molecular breast imaging: challenges and problem solving with contrast-enhanced spectral mammography.

Molecular breast imaging (MBI) is a relatively new technique with high sensitivity for breast cancer detection. However, because it only provides limited anatomical information, cross-correlation of MBI findings with conventional breast imaging modalities such as full field digital mammography can be challenging. We report a case of a positive MBI study in a supplemental screening setting, where cross-correlation of MBI, ultrasound, mammogram and biopsy findings was difficult. Contrast-enhanced spectral mammography (CESM) demonstrated a hypervascular lesion at the biopsy clip, helping to prove imaging/histopathological concordance. This case highlights the challenges of incorporating MBI into conventional imaging workup, as well as the use of CESM in problem solving.

Malignant hyperechoic breast lesions at ultrasound: A pictorial essay.

Malignant breast lesions are typically hypoechoic at sonography. However, a small subgroup of hyperechoic malignant breast lesions is encountered in clinical practice. We present a pictorial essay of a number of different hyperechoic breast malignancies with mammographic, sonographic and histopathologic correlation. Suspicious sonographic features in a hyperechoic lesion include inhomogeneity in echogenic pattern, an irregular margin, posterior acoustic shadowing and internal vascularity. A hyperechoic lesion at ultrasound does not discount the need to undertake histological assessment of a mammographically suspicious lesion.

Screen-detected breast carcinoma with macroscopic dystrophic calcification: A pictorial essay with radiolological pathological correlation.

Breast calcifications are among the most common abnormal radiographic findings detected at screening mammography. This essay illustrates the clinico-pathological features of nine screen-detected breast carcinomas, which had benign-appearing macrocalcifications, as a radiographically dominant presenting feature. We aimed to demonstrate that benign-appearing calcifications within a breast lesion are not diagnostic of a benign process if the other imaging characteristics of the lesion are suspicious of malignancy.

Review of ultrasound appearance in inflammatory breast cancer: A pictorial essay.

Inflammatory breast cancer (IBC) is a rare malignancy accounting for 1-2% of breast cancers. It has an aggressive clinical presentation and poor prognosis. The sonographic findings in 41 patients with a clinical diagnosis of IBC and biopsy-proven breast malignancy are presented in this study. The most common finding was the presence of skin thickening (92%). Multiple small anechoic spaces within the dermis, correlating with the presence of dermal lymphatic invasion by tumour emboli on histopathology were noted in approximately one-third of cases. Other sonographic findings included single or multiple masses, parenchymal oedema, axillary lymphadenopathy, echogenic foci consistent with microcalcifications and increased vascularity.

Radio-guided occult lesion localisation using iodine 125 Seeds "ROLLIS" to guide surgical removal of an impalpable posterior chest wall melanoma metastasis.

Cancer screening and surveillance programmes and the use of sophisticated imaging tools such as positron emission tomography-computed tomography (PET-CT) have increased the detection of impalpable lesions requiring imaging guidance for excision. A new technique involves intra-lesional insertion of a low-activity iodine-125 ((125)I) seed and detection of the radioactive signal in theatre using a hand-held gamma probe to guide surgery. Whilst several studies describe using this method to guide the removal of impalpable breast lesions, only a handful of publications report its use to guide excision of lesions outside the breast. We describe a case in which radio-guided occult lesion localisation using an iodine 125 seed was used to guide excision of an impalpable posterior chest wall metastasis detected on PET-CT.

Radioguided occult lesion localisation using iodine-125 seeds ('ROLLIS') for removal of impalpable breast lesions: First Australian experience.

INTRODUCTION: Approximately one-third of breast cancers are impalpable and require pre-operative image-guided localisation. Hook-wire localisation (HWL) is commonly used but has several disadvantages. Use of a low-activity radioactive iodine-125 seed is a promising alternative technique used in the USA and the Netherlands. This pilot study describes the first use of this in Australia. METHODS: In this prospective pilot study, 21 participants with biopsy-proven breast cancer underwent radioguided occult lesion localisation using iodine-125 seed(s) (ROLLIS) with insertion of a hook-wire for back up. Sentinel node biopsy was performed where indicated. Ease of hook-wire and seed insertion, duration of the procedure, dependence on the seed versus hook-wire during surgery, lesion location within the specimen, histopathology including size of radial margins, the ease of seed retrieval in pathology, and safe return of seeds for disposal were documented. Radiation dosimetry of staff was performed. RESULTS: All seeds were placed within 3.5 mm of the lesion. All lesions and seeds were removed. One participant needed re-excision for involved margins. Radiologists and surgeons both preferred ROLLIS. Surgeons were able to depend on the seed for localisation in all but one case. Sentinel node biopsy was successfully performed when required. Pathologists found seed retrieval quick and easy, with no detrimental effect on tissue processing. No radiation doses measurably above background were received by staff. CONCLUSION: ROLLIS is an easily learnt, safe and effective alternative technique to standard HWL.

Clinical and imaging features of male breast disease, with pathological correlation: a pictorial essay.

The majority of male breast diseases are benign. The most common is gynaecomastia. Although it is rare, the most critical diagnosis is a malignancy. Radiologists are generally less familiar with breast disease in males compared with females. This pictorial review will highlight the ultrasonographic, mammographic and pathological features of a spectrum of benign and malignant male breast diseases. This includes gynaecomastia, fat necrosis, lipoma, epidermoid cyst, subareolar abscess, chronic inflammation, melanoma and ductal carcinoma.
