A pseudophakic 70-year-old man presented to the clinic with a slow-growing conjunctival mass in the left eye. He was diagnosed with a conjunctival exophytic lesion suspicious of invasive conjunctival squamous cell carcinoma (CSCC). Excisional biopsy showed a well-differentiated CSCC with positive margins and the patient underwent adjuvant brachytherapy. Six weeks later, examination of the anterior segment revealed cells in the anterior chamber and a neurotrophic corneal ulcer with corneal perforation. Considering the high suspicion of intraocular invasion of CSCC, the left eye was enucleated...

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer, with a unique pathogenesis and distinct clinical biology. ILCs display a characteristic loss of E-cadherin, are largely estrogen receptor positive, HER2 negative, and low to intermediate grade. These features portend a favorable prognosis, but there is a tendency for late recurrences and atypical metastases. ILCs tend to be insidious and infiltrative, which can pose a challenge for diagnosis, and emerging data suggest they may have a propensity for a differing response to standard therapies...

REVIEW
Jennifer M Racz, Amy C Degnim
Atypical ductal hyperplasia (ADH) is a proliferative, nonobligate precursor breast lesion and a marker of increased risk for breast carcinoma. Surgical excision remains the standard recommendation following a core needle biopsy result consistent with ADH. Recent research suggests that women with no mass lesion or discordance, removal of greater than or equal to 90% of calcifications at the time of core needle biopsy, involvement of less than or equal to 2 terminal duct lobular units, and absence of cytologic atypia or necrosis are likely to have a less than 5% chance of a missed cancer...

The purpose of this study was to explore the clinicopathological features and survival outcome of pleomorphic lobular carcinoma (PLC) of breast, we identified 131 PLC patients and 460,109 invasive ductal carcinoma (IDC) patients in the Surveillance, Epidemiology, and End Result (SEER) database. PLCs presented with increased lymph node involvement, older age, higher AJCC stage and grade, and lower median survival months (PLC 84 ± 51.03 vs. IDC 105.2 ± 64.39 P < 0.01). Compared to IDC patients, PLC patients were more inclined to be treated with mastectomy...

Up to 40% of patients undergoing breast conserving surgery for breast cancer require repeat surgeries due to close to or positive margins. The lengthy processing required for evaluating surgical margins by standard paraffin-embedded histology precludes its use during surgery and therefore, technologies for rapid evaluation of surgical pathology could improve the treatment of breast cancer by reducing the number of surgeries required. We demonstrate real-time histological evaluation of breast cancer surgical specimens by staining specimens with acridine orange (AO) and sulforhodamine 101 (SR101) analogously to hematoxylin and eosin (H&E) and then imaging the specimens with fluorescence nonlinear microscopy (NLM) using a compact femtosecond fiber laser...

BACKGROUND: Invasive lobular breast tumors display unique reproductive risk factor profiles. Lobular tumors are predominantly Luminal A subtype, and it is unclear whether reported risk factor associations are independent of molecular subtype. METHODS: Polytomous logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the associations between risk factors and histologic subtype [ductal (n = 2,856), lobular (n = 326), and mixed ductal-lobular (n = 473)] in the Carolina Breast Cancer Study (1993-2013)...

BACKGROUND: Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of epithelial cells which is confined within the basement membrane of the mammary ductal-lobular system. It is of interest to determine to what extent the potential to metastasize increases for DCIS patients when the basement membrane is breached (i.e. microinvasion is present). METHODS: We retrieved the records of 525,395 women who had either first primary DCIS or small (≤ 2.0 cm) node-negative invasive breast cancer in the Surveillance, Epidemiology and End Results (SEER) registries database (1990-2013)...

INTRODUCTION: Pleomorphic lobular carcinoma in situ (PLCIS) is a variant of LCIS with high-grade morphologic features. The number of case series studying PLCIS is limited, and clinical management of patients with PLCIS is controversial. We report a breast core biopsy (BCBx) series of PLCIS. MATERIALS AND METHODS: We reviewed 37 cases of PLCIS with or without microinvasion diagnosed by BCBx. PLCIS was defined as dyscohesive cells showing acinar expansion and loss of immunohistochemical membranous expression of e-cadherin or beta-catenin with nuclear pleomorphism with at least 2- to 3-fold variation in nuclear size, membrane irregularities, and variably prominent nucleoli...

BACKGROUND: Our aim was to determine upgrade rates of pure flat epithelial atypia (FEA) to malignancy and higher-risk lesions and to identify patients with FEA at low risk for upgrade. STUDY DESIGN: Medical chart review from 2007 to 2016 identified 208 consecutive patients with pure FEA diagnosed by image-guided core needle biopsy who underwent surgical excision (96.2% [200 of 208]) or had at least 2 years of imaging follow-up (3.8% [8 of 208]). Medical records were reviewed for risk factors and surgical outcomes...

To our knowledge, this is the first report on basal cell carcinoma with lung metastasis in a rat. A 6-week-old male Sprague-Dawley rat presented ulceration of the oral mucosa with surrounding tumor growth and white nodules in the lung. Microscopically, the mass showed solid, sheet-like growth with a partially lobular pattern and invaded the gingival mucosa, maxilla, and nasal submucosa. The nuclei of tumor cells were round to oval in shape with basophilic cytoplasm and a large number of mitotic figures. The pulmonary nodules were almost identical to the maxillary tumor in histopathological characteristics...

Enophthalmos in the setting of breast cancer metastatic to the orbit results primarily from the disease pathogenesis, or secondary to treatment effects. Orbital volume restoration and fat regeneration following endocrine treatment monotherapy has not been previously reported. A 76- year-old previously healthy female presented with progressive right enophthalmos secondary to metastatic lobular breast carcinoma. Treatment with an aromatase inhibitor (letrozole) resulted in tumor regression and orbital fat restoration with a corresponding improvement in orbital volume and enophthalmos on clinical exam...

Xiaoyan Cui, Shi Wei
Ductal or lobular carcinoma in situ (DCIS/LCIS) can rarely arise from sclerosing adenosis (SA). The combination of cytologically malignant cells and the infiltrative growth pattern may make it challenging to distinguish it from an invasive carcinoma. The authors reviewed 50 consecutive cases of CIS involving SA to seek the salient histologic characteristics in order to prevent overdiagnosis. The features commonly seen with CIS were the lobular configuration at low magnification (94%), uninvolved SA in neighboring tissue (84%), at least focally identifiable myoepithelial cells on H&E-stained sections (76%), separate foci of unequivocal CIS (58%), associated microcalcifications (54%), and hyaline basement membrane surrounding tumor cell nests (48%)...

INTRODUCTION: In breast cancer patients, magnetic resonance imaging (MRI) is a supportive method characterized by high sensitivity. Its indications in the preoperative assessment are not clearly defined. More likely to benefit from preoperative MRI are younger women, women with a dense breast on mammography and patients with invasive lobular carcinoma (ILC). The aim of this study was to assess utilization of MRI and resulting benefits in preoperative tumour staging of ILC in patients treated in our institution...
