Myeloid sarcoma of the pancreas

Isolated granulocytic sarcoma of the pancreas: A tricky diagnostic for primary pancreatic extramedullary acute myeloid leukemia

We report two clinical cases of primary granulocytic sarcoma of the pancreas that were diagnosed on the surgical specimen. Atypical clinical and morphological presentations may have lead to pretherapeutic biopsies of the pancreatic mass in order to indicate primary chemotherapy. Literature review of this rare clinical presentation may help physicians to anticipate diagnostic and therapeutic str...

Myeloid Sarcoma

Myeloid sarcoma: extramedullary manifestation of myeloid disorders.

Myeloid sarcoma (MS), also termed extramedullary acute myeloid leukemia, extramedullary myeloid tumor, and granulocytic sarcoma or chloroma, is a rare manifestation that is characterized by the occurrence of 1 or more tumor myeloid masses occurring at an extramedullary site. The wide spectrum of this disorder and the conditions that it overlaps diagnostically were well reflected in the 25 cases...

Myeloid sarcoma involving the breast.

Myeloid sarcoma is a tumor mass with extramedullary growth pattern, composed of myeloblasts or immature myeloid cells. The development of myeloid sarcoma may precede or concur with acute or chronic myeloid leukemia (AML or CML) or other myeloproliferative diseases or myelodysplastic syndromes (MDS). Isolated myeloid sarcoma of the breast is very rare. A case is presented of a 25-year-old, previ...

Myeloid Sarcoma of the Kidney Preceding Acute Myeloid Leukemia

Myeloid Sarcoma is a rare extramedullary tumor, consisting of primitive granulocytic precursor cells. We report the case of a 50-year-old man, who presented with a renal mass. After nephrectomy, histological examination revealed a myeloid sarcoma in association with a renal cell carcinoma. Seven weeks after nephrectomy the patient developed acute myeloid leukemia.
