The Rare Diagnosis of Synchronous Breast and Colonic Cancers: A Case Report and Review of Literature.

Cureus 2021 Feb 12;13(2):e13314. Epub 2021 Feb 12.

General and Breast Surgery, Basildon and Thurrock University Hospital, Basildon, GBR.

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. Aetiological factors that may predispose patients to MPMNs have been grouped into three broad categories: familial cancer syndromes and other genetic susceptibility factors, common exposures (e.g. tobacco), and carcinogenic effects of cancer treatment. The likelihood of missing asymptomatic synchronous tumors at the time of diagnosis is due to a lack of definitively set guidelines for synchronous tumors. Studying every individual case may aid us in understanding disease biology, developing diagnostic guidelines, and establishing patient-specific management strategies. We present a case report of synchronous breast and colonic cancer in a female patient.

Breast Adenoid Cystic Carcinoma in a patient with Previous Contra-lateral Breast Ductal Carcinoma in-situ: A Case Report.

Chirurgia (Bucur) 2020 Jul-Aug;115(4):511-519

Breast adenoid cystic carcinoma (BACC) is a rarely encountered malignant breast neoplasm with a favourable outcome, despite its triple-negative receptor status. It is comprising less than 0.1% of all breast cancers. The more usual primary site of the adenoid cystic carcinoma is seen in the salivary glands, however BACC prognosis is better than the one for salivary gland and also than that of other breast invasive carcinoma. BACC also known to have fewer lymph node metastases as well as fewer distant metastases, hereby we present 73 years old female with previous history of breast ductal carcinoma in-situ, then developed contralateral breast adenoid cystic carcinoma.

The Challenge of COVID-19: The Biological Characteristics and Outcomes in a Series of 130 Breast Cancer Patients Operated on During the Pandemic.

Chirurgia (Bucur) 2020 Jul-Aug;115(4):458-468

The worldwide outbreak of the 2019 novel coronavirus disease (COVID-19) emerged in Wuhan, China close to the end of 2019. We analyse the clinical characteristics and management outcomes of a small group of patients who have been treated in the early stage of the COVID-19 disease, and discuss the impact of the pandemic on the service delivered to breast cancer patients. Material We analysed a cohort of 130 breast cancer patients who underwent elective surgical procedures during the early period of COVID-19. The patients were operated on in the period from March 16th, 2020 to May 18th, 2020. All the patients were female, with an age range of 33-88 years, with a median age of 57.6 years. Most of the cases were admitted as a day case surgery after passing through a preoperative screening pathway, which was developed gradually. Patients were contacted by phone after their surgery to ensure that they have had no symptoms and were reviewed in person two weeks after the procedure with histology results. Only one patient developed COVID-19 symptoms after surgery and recovered. Early and careful implementation of modified practice policies during emerging situation of viral pandemics will reduce the risk of perioperative complications, reduce the risk of patient to staff to patient transmission and minimize the negative impact of COVID-19 on breast cancer management.

Breast Atypical Apocrine Adenosis: A Case Report and Literature Review.

Cureus 2020 Jun 15;12(6):e8624. Epub 2020 Jun 15.

General Surgery, Mid and North Essex University Hospital Group, Basildon, GBR.

Atypical apocrine adenosis (AAA) is a benign lesion of the breast that is identified more frequently today than in the past when it was considered a rare diagnosis and commonly misdiagnosed as other malignant lesions of the breast. AAA is defined as the presence of apocrine cytology in a recognisable lobular unit associated with sclerosing adenosis. We present a case of an incidental finding of AAA and discuss diagnostic challenges and their implications on clinical management.

Posterior Mediastinal Paravertebral Müllerian cyst (cyst of Hattori): literature review.

Adv Respir Med 2020 ;88(2):134-141

Department of Cardiothoracic Surgery, Basildon and Thurrock University Hospital, Nethermayne, Basildon, Essex, United Kingdom.

Mediastinal cysts are typically of bronchogenic, thymic or neurenteric origin, but may also represent oesophageal duplication. Posterior paravertebral mediastinal Müllerian cysts of undetermined pathogenesis are very rare occurrences. The first case of a ciliated cyst arising in the mediastinum, of probable Müllerian origin, was reported by Hattori in 2005, which gave rise to the name cyst of Hatorri (COH) The number of reported cases in literature of a similar nature have since then increased significantly. One of the main concerns about this pathology is the possibility of malignant transformation of the Müllerian tissue. Over the course of this paper we will discuss the pathogenesis, immunohistochemistry and its role in differential diagnosis as well as optimal treatment of such cysts.

Colonic Goblet Cell Carcinoid: Rarity of a Rarity! A Case Report and Review of Literature.

Chirurgia (Bucur) 2020 Jan-Feb;115(1):102-111

Goblet cell carcinoids (GCC) are extremelyrare neuroendocrine tumours, and characterised by their unique combination of two types of cancer cells âÃÂ" neuroendocrine (carcinoid) and epithelial (adeno-carcinoma). In spite of the fact that GCC is regarded as Neuro-Endocrine Tumour (NET), it does not illicit carcinoid syndrome. GCC usually arises in the appendix and accounting for less than 14% of all appendiceal tumours.Primary extra-appendiceal GCC have been reported as stomach, duodenum, small intestine, colon and rectum. The paper presents a rare case of GCC of the ascending colon in a 57-year-old male.
