Аннотация
BACKGROUND: Granular cell tumors (GCTs) are rare soft tissue neoplasms, with invasive forms being exceptionally uncommon in the abdominal wall. This case highlights the diagnostic and therapeutic challenges of managing an invasive GCT in an atypical location.
CASE PRESENTATION: A 50-year-old male presented with a painless, enlarging mass in the left rectus abdominis, with no history of trauma or systemic symptoms. Imaging revealed an exophytic mass with ill-defined borders. Histopathological examination confirmed an invasive granular cell tumor. The patient underwent complete surgical resection with partial muscle excision, followed by abdominal wall reconstruction using mesh to prevent hernia formation.
CONCLUSION: Invasive GCTs can occur in the abdominal wall and require complete resection with meticulous reconstruction to ensure both oncological safety and functional integrity. This case underscores the importance of considering GCTs in the differential diagnosis of abdominal wall masses.
