Many skin lesions have been reported in connection with tattoos, both benign and malignant. The pathogenesis of malignant transformation in tattoos is unknown, although hypotheses include the toxic effects of the pigments. To date, we have notice 31 case reports and series (17 men, median age: 50.5 years) of KA and CSC on tattoos. Other Factors: UV exposure, fair skin, and immunosuppression increase incidence of cSCC. Recurrence and metastasis are associated with tumor diameter greater than 2 cm, depth greater than 2 mm or beyond subcutaneous fat, extensive or largecaliber perineural involvement, and poor differentiation on histopathology. AJCC 8 is used for TNM staging for cSCC of the head and neck. BWH offers an alternative T staging system. Management is primarily surgical with rare indications for adjuvant chemoradiation.
Dermatomyositis is a type of inflammatory myopathy characterized by inflammatory and degenerative changes of the muscles and skin. The Para neoplastic dermatomyositis is a subtype associated with cancer. The pathophysiothogy remains unfully understood. The diagnosis is supported by both the clinical and serological features. The treatment involves both the DM and the malignancy. Multi-disciplinary management is fundamental for patients. However the pronosis remains usually poor. We report a case of Para neoplastic dermatomyositis revealing an ovarian cancer; the purpose is to illustrate the diagnostic, therapeutic and pronostic of this entity
Clinical manifestations associated with covid-19 seem to be not limited to the lungs and widen to affect several organs including skin. Through two cases well documented, we report cutaneous manifestations strongly suggestive of Covid-19 which dermatologists are beginning to report worldwide and which we proposed to call them polymorphous acral eruption.
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.
