Introduction: COVID-19 disease is an acute viral pneumonia with multiple extrapulmonary manifestations, including certain hematological alterations. The leukoerythroblastic reaction or leukoerythroblastosis is defined by the presence in peripheral blood of nucleated erythroid cells and immature myeloids. Among its most frequent causes is medullary invasion by solid tumors and hematological neoplasms, so the recognition and consequent study of this reaction is extremely important. Read More

Background: Myelophthisis (MPT) has been associated with a dreadful prognosis. Patients' access to palliative care (PC) and factors influencing its clinical outcomes are poorly described. Our aim was to analyze the impact of patient- and disease-specific characteristics on survival of patients with MPT and describe their use of PC in a resource-limited setting. Read More

The infiltration of the bone marrow y non-hematopoietic cells is called myelophthisis. In patients with gastric cancer, this invasion is extremely infrequent and the survival is usually less than three months. We present the case of a 35-year-old man with bone marrow involvement secondary to diffuse gastric carcinoma of signet ring cells. Read More

Breast tumors have a predilection for metastasizing to the bone leading to cells being displaced by the cancer cells subsequently producing immature leukocytes and erythrocytes in the peripheral blood. We present a case of a 57-year-old female who was found to have myelophthisic anemia secondary to stage four lobular breast carcinoma metastasized to the bone marrow after being misdiagnosed as having thrombotic thrombocytopenia purpura. Diagnosis of myelophthisic anemia requires a thorough workup and treatment is based upon secondary management of the malignancy. Read More

Background: Leukoerythroblastosis, a non-specific and often short-lasting response of the bone marrow to different diseases such as malignancies or infections, is characterized by the presence in the peripheral blood of immature red and white cells.

Methods: We present a case of leukoerythoblastosis occurring in a 24 months old Mozambican girl, in the context of a severe malaria episode and an associated urinary tract infection. Peripheral blood smear was used for diagnosis of malaria and leukoerythroblastosis. Read More

Background: Myelophthisis due to melanoma is a rare phenomenon. Treatment strategies for patients with this serious complication of malignancy have not been well documented, and none have previously reported efficacy of immune checkpoint inhibition. Since bone metastases are not measurable lesions per standard response criteria, the efficacy of immune checkpoint inhibition in the bones is also not well described. Read More

Primary splenic angiosarcoma is an extremely agressive and rare neoplasm. Manifestations as bone marrow invasion and coagulation disorders have been reported isolatedly. A 26 years-old woman presented with abdominal pain; several anemia and thrombocytopenia associated to leukoerythroblastic reaction were found in the laboratory. Read More

Megaloblastic anaemia due to vitamin B12 deficiency is rare in childhood. However, as most cases are due to maternal insufficiency, it is mainly seen in breastfed infants especially when the mother's socioeconomic status is low and the nutrition is not adequate. We present case of two Syrian refugee infants with severe vitamin B12 deficiency with pancytopenia, hepatosplenomegaly and leukoerythroblastosis. Read More

The association of metastatic breast cancer presenting as thrombocytopenia and anaemia is demonstrated in the following case of a 79-year-old woman. Her main symptoms were abdominal pain, altered bowel habit and weight loss. Without a clear causative pathology, she underwent a CT scan which demonstrated multiple sclerotic bone lesions. Read More

Background: While basal cell carcinoma (BCC) remains the most common skin cancer, the incidence of metastasis is rare. Most cases of metastatic BCC have been to regional lymph nodes. Metastasis to bone marrow with myelophthisic anemia is especially rare. Read More

Primary myelofibrosis is a chronic myeloproliferative neoplasm characterized by cytopenias, leukoerythroblastosis, extramedullary hematopoiesis, hepatosplenomegaly and bone marrow fibrosis. Primary myelofibrosis is a rare disorder in adults; children are even less commonly affected by this entity, with the largest pediatric case series reporting on three patients. Most literature suggests spontaneous resolution of myelofibrosis without long term complications in the majority of affected children. Read More

Despite modern technological advancements in laboratory hematology, the blood film remains an important diagnostic aid. Herein, we report the case of a patient with a history of gastric cancer, who presented seven years following apparently successful surgery and adjuvant chemo-radio-therapy, with blood film findings of microangiopathic hemolytic anemia (MAHA), thrombocytopenia, and leukoerythroblastosis (LEB). Although mimicking features of thrombotic thrombocytopenic purpura (TTP), subsequent bone marrow examination instead revealed an association with occult recurrence of necrotic, metastatic gastric adenocarcinoma.

Ghosal hematodiaphyseal dysplasia syndrome (GHDD) is a rare clinical syndrome characterized by increased bone density and a severe, myelophthisic anemia. Few cases have been reported worldwide and there are no detailed descriptions of the associated hematologic abnormalities and long-term clinical outcomes after treatment. Here, we report two siblings with GHDD who were successfully treated with chronic, low dose, corticosteroid therapy. Read More

Osteopetrosis represents a heterogeneous group of rare, hereditary bone disorders with variable clinical features and an increase in bone density. The common clinical findings that usually lead to the detection of the disease are fractures and osteomyelitis of the mandible. We report 4 cases of osteopetrosis, complicated by osteomyelitis of the jaws. Read More
