Background:Breast cancer is the most common cancer in Iraq and the United Kingdom. While the disease is frequently diagnosed among middleaged Iraqi women at advanced stages accounting for the second cause of cancer-related deaths, breast cancer often affects elderly British women yielding the highest survival of all registered malignancies in the UK. Objective:To compare the clinical and pathological profiles of breast cancer among Iraqi and British women; correlating age at diagnosis with the tumor characteristics, receptor-defined biomarkers and phenotype patterns. Methods:This comparative retrospective study included the clinical and pathological characteristics of (1,940) consecutive female patients who were diagnosed with invasive breast cancer from 2014 to 2016 in Iraq (Medical City Teaching Hospital, Baghdad: 635 cases) and UK (John Radcliffe, Oxford and Queen's, BHR University Hospitals: 1,305 cases). The studied parameters in both groups comprised the age of the patient at the time of diagnosis, breast cancer histologic type, grade, tumor size, lymph node status, clinical stage at presentation, Estrogen Receptor (ER), Progesterone Receptor (PR) and HER2 positive tumor contents and the receptordefined breast cancer surrogate subtypes. Results:The Iraqi patients were significantly younger than their British counterparts and exhibited higher trend to present at advanced stages; reflected by larger size tumors and frequent lymph node involvement compared to the British (p<0.00001). They also had worse receptor-defined breast cancer subtypes manifested by higher rates of hormone receptor (ER/PR) negative, HER2 positive tumor contents, Triple Positive and Triple Negative phenotypes (p<0.00001). Excluding HER2 status, the significant differences in the clinical and tumor characteristics between the two populations persisted after adjusting for age among patients younger than 50 years. Conclusion:The remarkable differences in the clinical and tumor characteristics of breast cancer between the Iraqi and British patients suggest heterogeneity in the underlying biology of the tumor which is exacerbated in Iraq by the dilemma of delayed diagnosis. The significant ethnic disparities in breast cancer profiles recommend the prompt strengthening of the national cancer control plan in Iraq as a principal approach to the management of the disease. This comparative retrospective descriptive study included the clinical and pathological characteristics of (1,940) female patients diagnosed with invasive breast cancer in two countries; Iraq (635 cases) and UK (1,305 cases). The Iraqi GroupThis group enrolled 635 consecutive female patients who were diagnosed with breast cancer at the Referral Training Center for Early Detection of Breast Tumors, Medical City Teaching Hospital in Baghdad over a three-year period from 2014 to 2016. Data was extracted from an established information system database developed by the principal investigator under the direct supervision of the International Agency for Research on Cancer (IARC); utili...

Papillary lesions of breast represent a range of lesions. Intraductal papilloma and its association with nipple discharge are well known. However, multiple papillomatosis has quite distinct characteristics and decision making can be somewhat challenging. We report a case of multiple papillomatosis in association with ductal carcinoma in situ (DCIS). Patient opted for ipsilateral mastectomy and prophylactic mastectomy of contralateral breast. Her decision of having prophylactic mastectomy was vindicated by presence of incidental DCIS in the contralateral breast. To our knowledge, this is the first reported case of multiple papillomatosis with DCIS of breast, along with incidental synchronous papillomatosis of contralateral breast with DCIS. The case illustrates few distinct features of multiple papillomatosis of breast and exemplifies how a patient's choice is so paramount in decision making process. Patients should be fully informed of the treatment options of the condition, and their wishes should be fully taken into account while making the final decision.

Radiofrequency ablation is now widely used in the treatment of patients with snoring and obstructive sleep apnoea. It is well suited to the multilevel approach typically required in snoring surgery and can be used interstitially or in cutting mode. However, no research has been performed to analyse the collateral local tissue damage or size of lesions induced by radiofrequency application. This is the first study of the histological effects of interstitial radiofrequency. We studied the size of tissue lesions generated at differing power settings with and without local anaesthetic application in human tonsils and chicken breast tissue. The size of the lesion was independent of power setting and local anaesthetic infiltration. The typical effect was an oval-shaped lesion centred on the active electrode, 6-7 mm in width and 7-8 mm in length. This was confirmed histopathologically, with smaller lesions generated in the submucosa (2 × 3 mm) but with no collateral tissue damage beyond this distinct zone of injury. To avoid complications, we recommend placing contiguous radiofrequency applications at least 8 mm apart. Post-nasal space packing raises and tautens the soft palate. The use of local anaesthetic increases interstitial volume, thereby reducing the risk of incorrect probe placement and resultant ulceration or fistulation.

A 70-year-old Caucasian man with multiple comorbidities presented with a painless lump over the right parotid gland which was gradually increasing in size over the preceding 12 months. There were no systemic symptoms or facial weakness. Imaging indicated a benign tumour of the right parotid. Superficial parotidectomy was performed and the histology revealed a sialolipoma.

Displacement or seeding of malignant cells into the needle tract following percutaneous biopsy is a known phenomenon, although it does not affect disease recurrence or overall survival of patients with breast cancer. It has, however, been previously hypothesized that needle tract seeding may occasionally progress to clinical tumor recurrence, and there have been case reports of breast cancer recurrence that are likely to be related to needle tract seeding. We are presenting a case of invasive mucinous carcinoma of the breast with associated malignant cell seeding within the biopsy tract, which was diagnosed preoperatively on contrastenhanced MR imaging. A needle tract can often be visualized on contrast-enhanced MRI post biopsy and these changes may reflect tissue damage and regeneration only. In our case, an unusual nodular enhancement pattern was demonstrated along the biopsy needle tract, which was consistent with the histopathological finding of tumor seeding.
