Breast cancer is the most prevalent form of cancer worldwide. Every year, it affects a significant number of women in the UK and is considered one of the leading causes of cancer-related deaths globally. While breast cancer is primarily linked to adult women, its occurrence in children and adolescents is exceedingly rare.

Calciphylaxis, also called calcific uremic arteriolopathy, is a rare benign cutaneous manifestation. Although little is known about its pathogenesis, it is thought to be a result of vascular wall calcification leading to soft tissue necrosis, and it is usually encountered in patients with end-stage kidney disease (ESKD) on long-term renal dialysis. Breast calciphylaxis is a rare entity that may present as a breast mass or necrotic ulcers, and it is common for it to be initially mistaken for a malignant breast pathology.

Li-Fraumeni syndrome (LFS) is a rare inherited cancer susceptibility disorder with a wide tumour spectrum, particularly in children and young adults. Patients with LFS have life-long cancer risk, and the most commonly encountered tumours include soft tissue sarcoma, breast cancer, brain tumours, osteosarcoma, leukaemia and adrenocortical carcinoma. LFS is associated with mutations in the tumour suppressor gene andnearly two-thirds of families with LFS have this germline mutation.

Introduction Diverticula of the appendix is a rare entity, may be complicated by inflammation/infection, and clinically mimics acute appendicitis. The reported associated risk factors include male gender, Hirschprung's disease, cystic fibrosis and adult age, where some reports claim that they are also associated with an increased risk of appendiceal malignancy. Imaging has a place in pre-operative diagnosis, however, most of the cases were diagnosed during a pathological examination after surgery.

Carotid body tumours (CBT), also called carotid paragangliomas, are highly vascular glomus tumours that originate from paraganglionic cells of the carotid body. They are frequently asymptomatic, insidious, and non-secretory in nature. They typically present as a large, non-tender, pulsatile neck mass.

Globally, breast cancer is the most frequently diagnosed malignancy among women; it is also one of the leading causes of cancer mortality among females. The most common sites for metastases are the lungs, bones, liver, and brain. Breast cancer is recognized as one of the most common primary sites of metastatic lesions in the ovaries and is often associated with multiple extra-ovarian metastases.

Introduction Acute appendicitis is the most common general surgical emergency globally. Its etiology includes the presence of luminal obstruction by faecoliths, lymphoid hyperplasia, impacted stool, and rarely by appendiceal or caecal cancer. Malignancy related to acute appendicitis is usually seen in the older age group.

Breast apocrine cell pathology varieties include benign papilloma, non-high-grade apocrine ductal carcinoma in situ (DCIS), and breast invasive apocrine carcinoma (BAC). BAC is a rare type of invasive breast cancer and is histologically distinguished by large-sized cells with copious eosinophilic granular cytoplasm, round nuclei, and prominent nucleoli. Its prognosis is similar to breast invasive ductal carcinoma, of no special type (IDC-NST), when matched for tumour stage and histological grade.

Most patients with bowel cancer are symptomatic at the time of the diagnosis. They may present with a change in bowel habit, bleeding per rectum, abdominal pain, anaemia, weight loss or bowel obstruction. Colonic carcinoma can also be diagnosed incidentally during screening programs.

Any two or more primary malignant tumors, in which each tumor is not an extension, recurrence, or metastasis of the other lesion, are defined or described as multiple primary malignant neoplasms (MPMN). These tumors are increasingly diagnosed despite their rare occurrence rate. The term synchronous tumors is applied if two different tumors originating in the same patient are detected at the same time or within six months; if the second tumor is detected beyond six months, it is called metachronous.
