The plasma cell leukemia (PCL) is an extremely uncommon malignant blood disorder with a pejorative prognosis. It is defined by the presence of at least 20% of plasma cells in the peripheral blood or an absolute number of circulating plasma cells greater than 2 G /L. It appears under two variants: secondary PCL that complicates known multiple myeloma and primitive PCL that is immediately leukemic. We report the case of a 56 years old male patient who presented 2 months before his hospitalization diffuse bone pains with asthenia. The CBC revealed an anemia and a leukocytosis. The blood smear objectified 3 G/L circulating plasma cells. The bone marrow exam noted a rich cellularity and a marrow invaded up to 60% by dystrophic plasma cells. The clinical presentation of the plasma cell leukemia, its cytological smear characteristics, immunophenotypical, pathophysiological, therapeutic approach and outcome will be reminded in this article.
Avulsion fractures of the calcaneal tuberosity remains rare; they usually caused by forced ankle dorsiflexion; direct trauma occur infrequently; it must be treated immediately; to avoid the skin necrosis of the posterior heel; the treatment approach is of interest in this rare injury and the operative management is based on a review of the literature. ; Non operative treatment is classically associated with bad results. Hence the surgical intervention is generally the treatment of choice. The authors report two cases of unusual avulsion fractures of the calcaneal tuberosity treated by open reduction and internal fixation with a good functional result.
