Neurosarcoidosis, particularly in the absence of extra-neurologic systemic manifestations of sarcoidosis, is a challenging diagnosis that has a wide array of presentations. Most often presenting with cranial neuropathies, basilar meningitis or pituitary/hypothalamic dysfunction, isolated involvement of the spinal cord without cranial manifestations is exceptionally rare, often involving intramedullary lesions. Here, we present the unique case of a 64-year-old female with atypical neurosarcoidosis presenting with myelopathy from extra-dural nodules without other neurologic or systemic symptoms.

Acute leukemia with TCF3::ZNF384 is a distinct type of acute leukemia that present most commonly as B-acute lymphoblastic leukemia or mixed-phenotype acute leukemia (B/myeloid). We report the first case of TCF3::ZNF384 mixed-phenotype leukemia presenting as isolated extramedullary disease in the mediastinum. Diagnosis using RNA-sequencing and whole genome sequencing on the primary issue is illustrated.

Myeloid sarcoma (MS), an extramedullary form of acute myeloid leukemia (AML) is a rare tumor mass of myeloid blasts. It can disseminate to any one or multiple anatomical sites, with (synchronous MS) or without (isolated MS) bone marrow (BM) involvement. The aim of this review is to describe the most recent advances in MS regarding diagnosis, molecular background, various clinical manifestations from several organs, and treatment approaches.
