Les omphalolithes sont des concrétions crayeuses constituées de débris de kératine et de sébum, qui s’accumulent au niveau de l’ombilic. Peu d’observations ont été rapportées dans la littérature. Elles sont l’apanage des ombilics profonds, et sont parfois associées à une mauvaise hygiène. Elles peuvent passer inaperçues pendant des années ne se révélant qu’en cas d’inflammation, d’infection ou d’ulcération. Nous rapportons un cas particulier d’omphalolithe révélé par une tumeur ombilicale d’aspect framboisé.
Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis for which accurate epidemiological data are limited and therapy remains a challenge. The primary study’s aim was to examine all cases of PG observed in our department over a 6-year period in order to describe the relevant characteristics and outcome under therapy. Fourteen patients were included (5 women, 9 men). The average age of our patients was 40,15 years. The classical, ulcerative form was found in 10 cases (71.42%), the pustular form in 4 cases (27.57%) and PG was multifocal in 4 cases. The PG was located preferentially to the lower limbs. Histological examination was realized in all patients and objectified inflammatory infiltrate composed of polymorphonuclear neutrophils in all cases with vasculitis in 4 cases. Six patients (42.85%) had associated disease at diagnosis of PG, including inflammatory bowel disease in two cases (14.28%), a blood disease in 2 cases (14.28%), lymph node tuberculosis and inflammatory arthritis in 1 case (7%). The most frequent first-line treatments were oral corticosteroids (7 cases) and other treatments used were colchicine in 2 cases, topical corticosteroids in 3 cases with good clinical evolution. Our study confirms that PG is a rare disease, associated in almost half of cases with systemic disease already present at diagnosis; in our Moroccan background, it is most often inflammatory bowel disease, hematological or solid cancer and tuberculosis.
Introduction: Cutaneous Leishmaniasis is a parasitic infection encountered in our daily dermatologic practice. Case report: We present a case of 57 year-old man of Moroccan origin, with erythematous squamous and indurated plaque on the abdomen, treated as sarcoidosis with corticosteroids with no improvement. Discussion: Cutaneous Leishmaniasis is endemic in 88 countries. Aside from its classical presentation it can manifest in multiple different ways. In our case, the diagnostic of Erysipeloide Leishmaniasis was corrected on the basis of the skin smear and the histopathological examination. Our observation is particular in its clinical presentation and location. To our knowledge it is the first Moroccan case. Conclusion: Even in endemic countries it is worth reporting unusual forms and locations of Cutaneous Leishmaniasis in order to avoid inappropriate diagnosis and management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
