Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon benign mesenchymal tumor of the breast. Majority occur as diffuse lesions, and diagnosis is often incidental or in a background of other breast pathologies. Bilaterality with multiple tumoral masses in giant breasts is a rarity. We report a 34-year-old nonlactating female with 2-year history of rapid progressive painless bilateral enlargement of the breasts following surgical excision of ill-defined breast lumps which were not subjected to histopathological evaluation a year earlier...

The prolactin-inducible protein (PIP) is considered a valuable biomarker that is associated with both benign and malignant pathological conditions of the mammary gland. The function of PIP in breast tumorigenesis remains unknown; however, evidence from our laboratory and others suggest that it regulates host immunity. Studies with PIP-deficient (PIP-/- ) mice demonstrated significantly lower numbers of CD4+ T cells in their secondary lymphoid organs, impaired Th1 response, and impaired nitric oxide (NO) production...

Women with a benign breast disease (BBD) have an increased risk of subsequent breast carcinoma. Information is scarce regarding the characteristics of breast carcinomas diagnosed after a BBD. Our aim was to point out the differences in clinical and histologic characteristics of breast carcinomas diagnosed in women with and without a previous pathologic diagnosis of BBD in the context of population-based mammography screening. Retrospective cohort study of all women aged 50-69 years who were screened at least once in a population-based screening program in Spain, between 1994 and 2011 and followed up until December 2012...

RATIONALE: The ultrasound manifestations of granular cell tumor (GCT) is a consequence of the histopathological characteristic of the tumor and can be distinguished from breast cancer. PATIENT CONCERNS: A GCT is a rare, benign, hyperplasia-based lesion. Approximately 1% to 2% of GCTs are malignant. About 5% to15% of the cases occur in the breast, and it is relatively rare in the axillary accessory breast. There are no effective preventive measures for GCTs, early detection combined with a thorough and wide complete resection of the tumor remains the best treatment for a favorable outcome...

We describe a unique presentation of a rare disease presentation of a granular cell tumour. A 36-year-old woman presents with a large symptomatic left flank mass that had been slowly increasing in size. Multiple synchronous subcutaneous masses were found at presentation on the left breast, right auricle and right cheek. After diagnosis of granular cell tumour by core needle biopsy, the masses were excised with histopathological and immunohistochemical analysis of both specimens confirming the presence of non-malignant granular cell tumours...

Nodular fasciitis is a benign proliferation of fibroblasts and myofibroblasts most commonly found in the soft tissues of the upper extremities and the trunk of young to middle-aged adults. Nodular fasciitis is infrequently encountered in the breast and in the elderly. We report a case of a 69-year-old woman presenting with a palpable breast mass with imaging features that mimicked malignancy. Knowledge of this entity is important to allow proper radiological and pathologic concordance and patient management...

INTRODUCTION: There is controversy on the optimal work-up of screen-detected widespread breast calcifications: whether to biopsy a single target or multiple targets. This study evaluates agreement between multiple biopsy targets within the same screen-detected widespread (≥25 mm) breast calcification to determine if the second biopsy adds value. METHODS: Retrospective observational study of women screened in a statewide general population risk breast cancer mammographic screening program from 2009 to 2016...

Tubular adenoma of the breast is one of the most rare benign neoplasms, accounting for only 0.13% to 1.7% of all breast benign tumors. Little is known about this rare neoplasm as the current literature offers only some case reports or a few number of small series. The aim of our study is to provide some clinicopathologic features of the breast tubular adenoma. We retrospectively analyzed at our department of pathology all cases of breast tubular adenomas confirmed by immunohistochemistry over a period of 9 years (2009-2017)...

AIM: Fibroepithelial lesions (FELs) of the breast span a morphological continuum including lesions where distinction between cellular fibroadenoma (FA) and benign phyllodes tumour (PT) is difficult. The distinction is clinically important with FAs managed conservatively while equivocal lesions and PTs are managed with surgery. We sought to audit core biopsy diagnoses of equivocal FELs by digital pathology and to investigate whether digital point counting is useful in clarifying FEL diagnoses...
