[Pseudotumoral calcinosis of the wrist compressing the radial nerve in systemic sclerosis].

Background: Pseudotumoral calcinosis, a rare complication of systemic scleroderma, is characterized by the presence in extra-articular tissue, but rarely intra-articular tissue, of large masses made up of hydroxyapatite crystals.

Patients And Methods: We report an original case of intra- and extra-articular pseudotumoral calcinosis of the wrist diagnosed in a patient followed for mild systemic scleroderma. The calcinosis was revealed in a highly unusual way via ductal syndrome secondary to compression of the radial nerve in the wrist.

[Pancytopenia secondary to autoimmune myelofibrosis revealing a male case of systemic lupus].

Hematologic involvement is a common manifestation during systemic lupus erythematosus (SLE). Pancytopenia represents an infrequent mode of revelation, most often of peripheral origin, exceptionally secondary to a bone marrow disorder and particularly to an autoimmune myelofibrosis (AIMF). This entity, distinct from a primary myelofibrosis (MFP), is characterized by reticulin fibrosis of the bone marrow lack of atypical bone marrow cells, the presence of auto-antibodies and absence of classical signs of myeloproliferation.

Cannon Ball Diagnosis and Management in a Flight Attendant Candidate.

Background: ''Cannon ball'' opacities on chest X-rays are a common manifestation of hematogenous dissemination of a malignant tumor in the lungs. They indicate an advanced stage of disease with a very grim prognosis in terms of cure and survival. In aerospace medicine, this aspect means the patient is unfit for flight duties.
