• Aspiration

  A subsequent bone marrow biopsy and aspiration disclosed hypercellularity, and morphologic abnormalities within the megakaryocyte, erythroid, and myeloid series. [ncbi.nlm.nih.gov]

  Direct sequencing was performed using primer sequences and a previously described method.9Results Bone marrow aspiration presented 90% of undifferentiated blast cells (Figure 1) and Sudan black B (SBB) was negative. [htct.com.br]

  Spicules were not present on the aspirate or touch preparation. Flow cytometry showed a myeloid immunophenotype, with the presence of an intermediate to large sized myeloid blast cell population ( Figure 5 ). [hoajonline.com]

• Hepatosplenomegaly

  A 62-year-old female patient presented with thrombocytopenia, isolated hepatosplenomegaly, and extremely high levels of LDH. [ncbi.nlm.nih.gov]

  His physical examination revealed irritability, bronchospasm, and hepatosplenomegaly. Laboratory tests showed a white blood cell count (WBC) of 10.6×109/L with 3% blasts, hemoglobin of 9.0g/dL and a platelet count of 10×109/L. [htct.com.br]

• Skin Lesion

  This association is possibly not fortuitous, particularly since most ring chromosome 7 patients reported to date have pigmented skin lesions. [ncbi.nlm.nih.gov]

  However, patients with partial trisomy have speech difficulty as a distinguishing feature, while patients with partial monosomy have skin lesions as a cardinal feature. [ingentaconnect.com]

Anti-epileptic drugs are the mainstay and first line of treatment; however no one drug or treatment has been shown to be better than others. Patients are frequently exposed to multiple anti-epileptic drugs. [epilepsy.com]
