Background. Nowadays the newest method of nutrition in patients with head and neck carcinomas is the use of percutaneous endoscopic gastrostomy. Aim. Since 2012 we have actively implemented the use of Nutrison administered on PEG before and after the surgical removal of laryngeal or pharyngolaryngeal carcinomas. Material and method. We conducted a prospective descriptive study on 54 cases that benefited from prophylactic PEG placement. Results. Among the cases included in our study 28 underwent total laryngectomy with bilateral removal of lymph nodes, 23 patients required pharyngo-laryngectomy

We hereby present the case of a 58-year-old male who underwent a total gastrectomy for gastric neoplasm. During the surgery, a tumor mass in the jejunum was identified, considered as metastasis, and resected. The histopathological examination of the jejunal lesion showed ectopic pancreas. In this area, two pathological distinct lesions were identified, one histologically compatible with pancreatic intraepithelial neoplasia (PanIN) type 2 lesion and the other with morphologic criteria for endocrine microadenoma.

Abstract:

Adenocarcinomas and noninvasive intraepithelial neoplasms (either polypoid or flat) are the most common gallbladder tumors; however, neuroendocrine neoplasms (NENs) can also occur. The majority of NENs are represented by neuroendocrine carcinomas (NECs), while neuroendocrine tumors (NETs) are extremely rare in this location. Occasionally, NEN may present as a part of a mixed neoplasm, with a coexisting non-neuroendocrine component. The latest World Health Organization classification denotes these lesions as mixed neuroendocrine–non-NENs (MiNENs). A novel type of MiNEN, the mixed adenoma well-d

Abstract:

Abstract Introduction In patients treated with an appendectomy for acute appendicitis, the specimen is generally sent for histological evaluation. In an era of increasing non-operative treatment for acute appendicitis, it is important to know the incidence, the diagnostic accuracy, and treatment consequences of appendicular neoplasms that are found in acute appendicitis. We hypothesize that pre- and intra-operative parameters might predict an appendicular neoplasm. Methods Data was used from our previous prospective observational cohort study. All patients undergoing surgery for suspected acut

In a 2-year survey of tumors occurring in ruminants reared in El-Dakahlyia Governorate, Egypt during the period from October 2016 to October 2018. 66 tumor masses were collected: 60 from cattle, 2 from buffaloes and 4 from sheep. According to histopathology of cattle tumors, 15 neoplasms were diagnosed as cutaneous papilloma, 5 neoplasms were diagnosed as cutaneous fibropapillomas, 25 neoplasms were diagnosed as squamous-cell carcinoma (SCC) of the eye; 8 neoplasms were diagnosed as SCC of perineum, 1 neoplasm was diagnosed as SCC in skin of muzzle, 2 neoplasms were diagnosed as epulis in dent

Abstract:

Clear cell sarcoma of kidney is an uncommon neoplasm accounting for approximately 5% of all pediatric renal neoplasms, with a peak incidence between 1-3 years of age. Males are most commonly affected (M:F ratio – 2:1). It is a highly malignant neoplasm with a high propensity than other renal neoplasms to metastasize to bones, hence originally called as bone-metastasizing renal tumour of childhood by Marsden and Lawler. We describe here 2 case reports of clear cell sarcoma of kidney.

Abstract:

Context.— Cellular basaloid neoplasms of the salivary gland represent a diverse group of benign and malignant neoplasms with significant cytomorphologic overlap on fine-needle aspiration cytology. All are marked by the presence of monotonous and usually bland basaloid epithelium. Distinction between basaloid neoplasms on fine-needle aspiration cytology is based on the presence or absence of additional features, including a second cell population (eg, myoepithelial cells), an acellular stromal component, and/or cytologic atypia within the basaloid epithelium. This review highlights the cytomorp

Abstract:

Abstract Epidemiological studies of atomic-bomb survivors have revealed an increased risk of lymphoid neoplasm (i.e. acute lymphoblastic leukemia) associated with radiation exposure. In particular, children are more susceptible to radiation-induced precursor lymphoid neoplasm than adults. Although ~75% of human lymphoid tumors are B-cell neoplasms, the carcinogenic risk associated with each stage of differentiation of B-cells after radiation exposure is poorly understood. Therefore, we irradiated mice at infancy or in young adulthood to investigate the effect of age at exposure on the risk of

Pancreatobiliary tract lesions are increasingly being discovered because of more sensitive imaging modalities. Magnetic resonance imaging has identified incidental pancreatic cysts in 13.5% of patients of progressively increasing age. Pancreatobiliary tissue is more accessible through endoscopic ultrasound and magnetic resonance imaging–guided biopsy procedures, and is now an integral part of pathologists' routine practice. Accordingly, several new tumor categories have been recently recognized, including intraductal tubulopapillary neoplasm, a new addition to tumoral intraepithelial neoplasms

The cells' role in the neoplasms is a reactive one or, more rarely, as an integral element in an osteoclast-type giant cell neoplasm or so-called osteoclastoma. Distinctive in histological appearance, the osteoclast-type giant cell neoplasm is a malignant lesion that, to date, has been described only in the pancreas and parotid glands. This report presents examples of each type of giant cell lesion in the parotid gland.

The formation of malignant neoplasm can be seen as deterioration of a pre-malignant skin neoplasm in its functionality and structure. Distinguishing melanocytic skin neoplasms is a challenging task due to their high visual similarity with different types of lesions and the intra-structural variants of melanocytic neoplasms. Besides, there is a high visual likeliness level between different lesion types with inhomogeneous features and fuzzy boundaries. The abnormal growth of melanocytic neoplasms takes various forms from uniform typical pigment network to irregular atypical shape, which can be
