RESUMO

INTRODUCTION: Scrotal calcinosis is a benign idiopathic cutaneous calcinosis characterized by the presence of calcified nodules of the scrotal skin. The aim of the study is to report the clinical, histological and therapeutic aspects. PATIENTS AND METHODS: This was a prospective descriptive study from 2014 to 2020 in the department of urology. Patients were included, aged at least 15years, consulting for nodules of the scrotal skin whose clinical and paraclinical assessment concluded to scrotal calcinosis. The variables studied were clinical, paraclinical, therapeutic and evolutionary. Informed consent of the patients and anonymity in the use of scientific photographs were observed. RESULTS: In 6years, 8 cases of scrotal calcinosis were diagnosed and operated on, i.e. 1.3 per year. The average age of the patients was 36.2years. The average age of the lesions was 4.2years, the general condition was good (n=8). The unsightly appearance (n=5), pruritus (n=2), recommendation of the spouse (n=2), psychological trauma (n=5), and fear of cancerous degeneration (n=3) were the reasons for consultation. The lesions were scattered or in clusters. Serologies were positive: HIV (n=2), chlamydia (n=4) and syphilis (n=3). Treatment was surgical (n=8). Histological analysis concluded to scrotal calcinosis. The average hospital stay was 2days. The mean time to complete healing was 19.6days without recurrence. CONCLUSION: Scrotal calcinosis is a benign, rare idiopathic pathology. The treatment is surgical.

RESUMO

Undifferentiated carcinoma of the nasopharynx (UCNT) has variable incidence throughout the world. Senegal is supposed to be a non-endemic zone. There is a constant connection with the Epstein-Barr virus. In this work, the authors study and discuss the pathological aspects of undifferentiated carcinoma of the nasopharynx in 13 cases. They also seek to make the link between this cancer and the presence of an Epstein-Barr virus infection in these patients. This is a retrospective series of cases involving patients with UCNT, diagnosed on histological basis in Dakar and confirmed by immunohistochemistry. An EBV search was performed on these cases through in situ hybridization by the EBER probe. 15 cases diagnosed on histological basis were able to benefit from immunohistochemistry, and 13 cases were confirmed, ie 87%. The mean age was 28.37 years with extremes of 5 and 56 years. The male sex predominated, with a sex ratio of 8/3. The macroscopic lesions were of ulcerous-budding type for cases revealed by a mass of the cavum. The histological aspect resulted in a proliferation of atypical undifferentiated cells, with large, clear, strongly nucleated nuclei, with eosinophilic cytoplasm, scarcely abundant. The stroma was of the lymphoid type. In situ hybridization with the EBER probe showed moderate or intense diffuse scarring of the tumor cells for 10 cases, ie 77%. The number of cases noted in our study taking into account the period of 10 years considered, is indicative of the rare nature of this type of cancer in Dakar. While globally, Epstein-Barr Virus is consistently associated with UCNT, for some of our cases we have not been able to highlight EBV, suggesting the possible involvement of other risk factors, such as HPV.


Les auteurs étudient et discutent les aspects anatomopathologiques du carcinome indifférencié du nasopharynx (UCNT) au Sénégal à propos de 13 cas. Ils recherchent par ailleurs à faire le lien entre ce cancer et la présence d'une infection par le virus d'Epstein-Barr (EBV) chez ces patients. Il s'agit d'une série rétrospective de patients porteurs d'UCNT, diagnostiqués sur base histologique à Dakar sur 10 ans, et confirmés par l'immunohistochimie. Une recherche d'EBV a été effectuée sur ces cas en hybridation in situ par la sonde EBER. Quinze cas diagnostiqués sur base histologique ont pu bénéficier de l'immunohistochimie et 13 cas ont été confirmés, soit 87 %. L'âge moyen était de 28,37 ans avec des extrêmes de 5 et 56 ans. Le sexe masculin prédominait, avec un sex-ratio de 8/3. Les lésions macroscopiques étaient de type ulcéro-bourgeonnant pour les cas se révélant par une masse du cavum. L'aspect histologique se traduisait par une prolifération de cellules indifférenciées atypiques, aux noyaux volumineux, clairs, fortement nucléolés, aux cytoplasmes éosinophiles, peu abondants. Le stroma était de type lymphoïde. L'hybridation in situ avec la sonde EBER montrait un marquage diffus modéré ou intense des cellules tumorales pour 10 cas, soit 77 %. Le nombre de cas notés dans notre étude, tenant compte de la période de 10 ans considérée, est révélateur du caractère rare de ce type de cancer à Dakar. Si à l'échelle mondiale, le virus d'Epstein-Barr est constamment associé à l'UCNT, pour certains de nos cas nous n'avons pas pu mettre en évidence EBV, suggérant l'implication possible d'autres facteurs de risque, tel que le papillomavirus humain (HPV).

RESUMO

La tumeur d'Abrikossoff ou tumeur à cellules granuleuses est une lésion rare, souvent unique et bénigne. L'âge de son diagnostic habituellement est compris entre 40 et 60 ans. Elle prédomine légèrement chez les femmes, notamment de race noire. Elle est de siège ubiquitaire et préférentiellement cervico-céphalique. La langue reste la localisation la plus fréquente avec 28% des cas. Les autres localisations sont beaucoup moins fréquentes. Nous rapportons le premier cas documenté au Congo Brazzaville, de localisation gastrique, suivi d'une revue de la littérature
