Benign Nasosinus Tumors: Epidemiological, Clinical, Morphological, Therapeutic, and Evolutionary Aspects at the Adolphe SICE General Hospital in Pointe-Noire (Congo-Brazzaville)

Introduction: Benign nasosinus tumors (BNST) of epithelial origin are relatively rare and arise from the various lining tissues of the nasal and sinus cavities, and from glands developed from these epithelial invaginations. These include nasosinusal polyps, pleiomorphic adenoma and inverted papilloma. The aim of our study was to investigate the epidemiological, clinical, morphological, therapeutic, and evolutionary particularities of these three clinical entities, including two tumors with the potential for progressive malignancy (pleiomorphic adenoma and inverted papilloma) and one strictly benign tumor with a favorable evolution (nasosinus polyp or Schneider polyp). Materials and Methods: This was a retrospective, analytical, cross-sectional study conducted from January 1, 2006 to December 31, 2019 (13 years), in the Department of Otolaryngology and Cervicofacial Surgery at Adolphe SICE Hospital, Pointe-Noire, Congo-Brazzaville. Results: During the study period, 74 patients were registered for a nasosinus tumor, of which 23 were benign tumors of epithelial origin (31%) distributed as follows: 15 cases of nasosinus polyp, 5 cases of pleomorphic adenoma and 3 cases of inverted papilloma. The mean age was 42.5 for polyps, with an estimated median of 38, and 42.9 for the other two entities (pleomorphic adenoma and inverted papilloma), with an estimated median of 41. Nasosinus allergy accounted for 17% of cases, followed by chronic sinusitis (12%);however, in 49% of cases, the patient’s history was not specified. There was no sexual predominance, the sex ratio being 1.08. Occupation, socio-economic level, and education had no impact on the development of these tumors. Most of our patients (52%, 12 cases) had a consultation delay of more than one (1) year, whatever the histological nature of the tumor. The complete nasosinus syndrome (NSS) included nasal obstruction, rhinorrhea, epistaxis, and anosmia, and was found in 19 cases (83%), most often reflecting a nasosinus p

The pathology of urinary bladder lesions with an inverted growth pattern

引用

Chinese Journal of Cancer Research 2016年第1期28卷 107-121页

inverted lesions in the urinary bladder have been the source of some difficulty in urological pathology. The two common ones are von Brunn＇s nests and cystitis cystic/cystitis glandularis, which are considered normal variants of urothelium. Apart from them, a number of other rare urothelial lesions with inverted growth pattern occur in the urinary bladder. Some of them are only reactive conditions, just as pseudocarcinomatous hyperplasia. Some are benign tumors, namely inverted papilloma. Whereas others are malignant neoplasms, including inverted papillary urothelial neoplasm of low malignant potential （PUNLMP）, non-invasive inverted papillary urothelial carcinoma （low-grade and high-grade）, and invasive urothelial carcinoma （inverted, nested and big nested variants）. Because of the overlapping morphological features of all the inverted lesions mentioned above, even between high-grade invasive carcinoma and psendoearcinomatous hyperplasia which are only a kind of reactive conditions, it is very important for the surgical pathologist to recognize and be familiar with these inverted lesions in urinary bladder. In this article, we review these spectrums of inverted lesions of the urinary bladder. Emphasis is placed on histogenesis, morphology, differential diagnosis of these lesions, and the pathologic grading of the non-invasive inverted neoplasms, such as inverted papilloma, inverted PUNLMP, non-invasive inverted papillary urothelial carcinoma with low-grade, and non-invasive inverted papillary urothelial carcinoma with high-grade.
