A 59 year old man with myelofibrosis, who underwent cholecystectomy for chronic cholecystitis, showed myeloid metaplasia in his gall bladder. Pathologically, this may lead to diagnostic difficulties.
متن کاملSplenectomy in myeloid metaplasia.

Twenty-five of 26 patients with painful splenomegaly, 4 of 9 patients with refractory hemolytic anemia, 4 of 10 patients with refractory thrombocytopenia, and 4 of 4 patients with portal hypertension showed significant benefit from the procedure. There were five immediate postoperative deaths. Four of thes...
متن کاملSplenectomy and risk of blast transformation in myelofibrosis with myeloid metaplasia. Italian Cooperative Study Group on Myeloid with Myeloid Metaplasia.
An unexpectedly high incidence of blast transformation after splenectomy has been reported in patients with myelofibrosis with myeloid metaplasia. However, whether this was associated with spleen removal after adjustment for risk factors was not determined. We conducted a multicenter historical cohort study of patients with myelofibrosis with myeloid metaplasia diagnosed from January 1970 throu...

MMM usually presents with fatigue, weight loss, splenomegaly with or without symptoms. Anemia and various alterations of the white blood cell and/or platelet count are frequently seen at diagnosis. Thrombocytopenia-related bleeding may occur. MMM must be distinguished from myelodysplasia with fibrosis, from acute megakayoblastic leukemia and acute myelofibrosis. As the disease progresses, incre...

It is usually a solitary lesion and is most commonly found on the face and upper extremities, appearing as a firm, dermal nodule covered by the normal skin.
