Abstract
BACKGROUND

Mast cell leukemia (MCL), a subtype of systemic mastocytosis (SM), is an extremely rare clinical entity characterized by a very poor prognosis. Chemotherapy, tyrosine kinase inhibitors, and allogeneic hematopoietic cell transplantation are the only treatment options, but they cannot provide the desired outcomes in most cases of MCL. However, other types of SM can be successfully treated. The disease has no specific manifestation, but gastroenterological symptoms are present in most cases.

CASE SUMMARY

The authors, hereby, report a case of a 46-year-old female patient diagnosed with MCL-the rarest subtype of SM. The patient presented to the gastroenterology clinic with multiple, various, and unspecific gastroenterological symptoms. Concomitance of skin lesions significantly contributed to a relatively prompt diagnosis. The serum tryptase level was extremely high and bone the marrow aspirate showed an infiltration of atypical mast cells. The disease was rapidly progressive and primary refractory to chemotherapy and the patient succumbed to the illness about a month after the initiation of treatment.

CONCLUSION

Despite its “hematological nature”, MCL, in most cases presents dominantly with unspecific gastroenterological symptoms. Thus, a high disease awareness among physicians other than hematologists is necessary to improve treatment outcomes. Serum tryptase level, due to its non-invasive nature and easy access, may serve as an initial step to estimate the probability of mastocytosis.

Core Tip: Mastocytosis is a group of neoplastic diseases characterized by excessive proliferation and infiltration of pathologic mastocytes into many organs in the human body. The clinical course of the illness may vary from indolent types, with average life expectancy, to advanced severe forms associated with poor prognosis. A disease may present with plenty of unspecific symptoms resulting in a long-lasting diagnostic process. We report a rare case of mast cell leukemia (MCL) in a 46-year-old female with weakness, unintentional weight loss, spine pain, vomiting, diarrhea, and epigastric pain occurring within several months before hospitalization. Although MCL is still associated with a high morbidity index, other less aggressive forms of systemic mastocytosis may be successfully treated with chemotherapy.
