[Adult non-Hodgkin bone lymphomas].

Two forms of bone lymphomas can be distinguished: the primary bone lymphoma (PBL) and the secondary bone lymphoma (SBL). PBL is a rare disease with a good prognosis. Clinical manifestations and imaging findings are usually non-specific.

[Isolated plasmablastic lymphoma of nasal mucosa in an immunocompetent patient achieving complete remission after multimodal treatment: about an African patient and literature review].

Plasmablastic lymphoma is an aggressive variant of lymphomas recently distinct from diffuse large B cell lymphoma. It has been initially described as a disease affecting the oral cavity of immunocompromised patients. We here report the first case of a 54-year-old patient with nasal septum nodule, bleeding on contact and after sneezing which occurred 6 months before admission.

[œsotracheal fistula complicating primary mediastinal large B cell non-Hodgkin's lymphoma: a case study].

Primary mediastinal non-Hodgkin's lymphoma(PMNHL) is a rare cancer. Exceptionally, it can be complicated by tracheœsophageal fistulas, directly connecting the esophagus and the trachea and secondary to esophageal tumor or chemotherapy (hence the interest of our case). We report the case of a 24-year old Moroccan female patient, treated for primary mediastinal large B cell NHL revealed by dyspnœa associated with dysphagia and alteration of general condition.

[Severe acquired marrow aplasia and seronegative autoimmune hepatitis: a rare and serious association].

Post-hepatitis marrow aplasias are severe aplasias occurring in the six months following at least one episode of early onset hepatitis, usually seronegative for hepatitis viruses known. We report the case of a 28-year old patient with autoimmune hepatitis revealed by jaundice associated with hepatomegaly and hepatic cytolysis and confirmed by liver biopsy; four months later it was complicated by pancytopenia associated with severe marrow aplasia.
