In this report, we present a 53-year-old woman with primary mast cell sarcoma of the thoracic spine vertebrae. Mast cell sarcoma is an aggressive and rare cancer. [ncbi.nlm.nih.gov]

A prominent, patchy infiltrate of eosinophils was also present. Scattered very large epithelioid cells were also present; these often showed bizarre features, including multilobated nuclei and multinucleation. [nature.com]

A bone scan, GI workup, and identification of the D816V c-kit mutation can also be helpful in cases where the diagnosis requires confirmation. [msdmanuals.com]

For example, a GI workup is dictated by symptoms of GI involvement, and lymph nodes are biopsied if lymphoma is suspected Narcotic analgesics should be used with care, particularly at high doses Cladribine, a nucleoside analog, does not appear to require [slideshare.net]

Mast cell sarcoma is an extremely rare and aggressive disease characterized by local proliferation of atypical mast cells, destructive growth and poor prognosis, without systemic involvement. [ncbi.nlm.nih.gov]

Prognosis The prognosis is very poor. Mast cell sarcoma quickly becomes mast cell leukemia. PREVENTION No preventative measures exist. [knowcancer.com]

In SM-AHNMD, the prognosis depends on the course of the associated haematological disorder. Agressive systemic mastocytosis and mast cell leukaemia have a poorer prognosis. [patient.info]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

Etiology in many patients involves an activating mutation (D816V) in the gene coding for the stem cell factor receptor c-kit, which is present on mast cells. [msdmanuals.com]
