“…Delayed treatment leads to poor outcomes. Recently, Cavalcante et al also reported a lower gingival rhabdomyosarcoma mimicking a reactive proliferative lesion in a 30-year-old female [ 17 ]. The tumor presented as a well-defined polypoid nodule on the mandibular gingiva clinically, and it was misdiagnosed as pyogenic granuloma.…”

“…The tumor presented as a well-defined polypoid nodule on the mandibular gingiva clinically, and it was misdiagnosed as pyogenic granuloma. They also emphasized the importance of the careful histopathological evaluation, supported by immunohistochemistry analysis which is the key to avoid diagnostic errors [ 17 ]. Although a standard therapy is not yet established in the rare group of adult patients with RMS, many studies have suggested that a multimodal approach will achieve the best possible outcome [ 10 ].…”

Background According to previous research, 2.8% of lesions clinically identified as endodontic pathosis were ultimately diagnosed as non-endodontic periapical lesions via histopathology, and 3.7% of these non-endodontic periapical lesions were malignant neoplasms. Rhabdomyosarcoma, a malignant tumor most commonly observed in children, is uncommon in the oral cavity. Case presentation This is a report of a rare case of embryonal rhabdomyosarcoma in a 41-year-old female, in which the lesion was in the maxillary gingiva. The biopsy reports confirmed the diagnosis of embryonal rhabdomyosarcoma. The wide excision of the tumor, free flap reconstruction, chemotherapy, and radiotherapy were performed. Clinical, radiological, and histopathological and management aspects of the neoplasm were also discussed. Conclusions This case report aimed to create awareness that rhabdomyosarcoma is one of the differential diagnoses of periapical lesions.
