Coexistent systemic amyloidosis, multiple myeloma, and refractory anemia with ringed sideroblasts in a previously untreated patient

A Rare Presentation of Multiple Myeloma: A Case Report of Hepatic Amyloidosis

The clinically reported case of liver involvement with multiple myeloma (MM) is rare. Amyloidosis, defined as a tissue deposition of clonal light-chain fibrils, has been reported in 10-15% of the MM patients. We described a rare MM patient with the primal presentation of fulminant hepatic failure and biliary system involvement due to amyloidosis. Our patient had the primal symptoms of hyperbili...

An MPL W515L mutation in refractory anemia with ringed sideroblasts associated with marked thrombocytosis: A case report

The current study presents the case of a 63-year-old patient exhibiting refractory anemia with ringed sideroblasts associated with marked thrombocytosis (RARS-T), who was positive for the MPL W515L mutation, but negative for the JAK2 V617F mutation. Following diagnosis, the patient remained asymptomatic for over three years, however, in August 2012, the patient relapsed and was administered wit...

Refractory anemia with ringed sideroblasts associated with marked thrombocytosis (RARS-T), another myeloproliferative condition characterized by JAK2 V617F mutation.

JAK2 V617F mutation recently was identified as a pathogenic factor in typical chronic myeloproliferative diseases (CMPD). Some forms of myelodysplastic syndromes (MDS) show a significant overlap with CMPD (classified as MDS/MPD), but the diagnostic assignment may be challenging. We studied blood or bone marrow from 270 patients with MDS, MDS/MPD, and CMPD for the presence of JAK2 V617F mutation...

A case of primary systemic amyloidosis with nail dystrophy

We hereby report a 79-year-old Iranian man presenting with nail dystrophy and subsequent development of purpuric and ecchymotic plaques, hemorrhagic bullae, and infiltrated papules on the head, neck and trunk. Histological examination of the gingiva, bone marrow aspiration, and biopsy confirmed the diagnosis of primary systemic amyloidosis. In this case, nail dystrophy was the presenting sign o...
