Abstract
BACKGROUND

Myeloid sarcoma (MS), also referred to as granulocytic sarcoma or chloroma, is a rare type of extramedullary malignant tumor. MS comprises primitive granulocytic precursor cells that play a key role in the early stages of white blood cell development. Notably, the occurrence of this tumor in the gingiva is rare.

CASE SUMMARY

The present study reported the case of MS with gingival swelling in the maxillary region, with aleukemic presentation in a 32-year-old male patient. Following two courses of chemotherapy, computed tomography of the region demonstrated complete clearance of the tumor. At the 12-month follow-up appointment, the patient was in a stable condition with the absence of progression. The etiology, clinical features, diagnosis, and relevant treatment of MS are discussed in the present study.

CONCLUSION

Diagnosis of MS may be confirmed following histological and immunohistochemical examinations.

Core Tip: We report a rare case of myeloid sarcoma (MS) with maxillary gingival swelling as the initial symptom. In this case, histopathological and immunohistochemical analyses showed diffuse infiltration of myeloperoxidase-positive neoplastic cells with 80% Ki-67 staining, indicating MS. Flow cytometry revealed a predominance of granulocytes without distinct B-cell or T-cell markers, supporting the diagnosis. Absence of CD20 and CD3 markers lessened lymphoma likelihood, confirming the lesion's hematopoietic nature.
