RESUMO
INTRODUCTION: Extraskeletal soft tissue chondroma (STC) is a rare benign tumor. Soft-tissue chondromas rarely occur in the oral cavity. In this study, we aimed to confirm a slow-growing tongue mass using magnetic resonance imaging. PATIENT CONCERNS: A 60-year-old woman presented with a painful, slow-growing tongue mass that had persisted for 17âyears. Intraoral examination revealed a pedunculated mass covered with mucosa on the right side of her tongue. DIAGNOSIS: CT and MRI revealed a lobulated heterogeneously enhancing mass without calcification. Compared with previous images obtained 17âyears prior, the mass presented slow growth, more prominent enhancement, and lobulated contour. Histopathological examination confirmed the presence of STC. INTERVENTIONS: Excision of the mass surrounding normal tissue was performed under general anesthesia. OUTCOMES: During 1-year follow-up period, no recurrence was observed. CONCLUSIONS: In this study, STC lesions were slow-growing, and changed from weakly homogeneous enhancement and clean margins to markedly heterogeneous enhancement and lobulated margins over time.

Vascular leiomyoma (VL) is a solitary and rare form of leiomyoma that usually occurs in the skin or subcutaneous tissue of the lower extremities. Intranasal VL is extremely rare, probably due to the lack of smooth muscle in the nasal cavity. In this study, we report a case of a 70-year-old woman with VL of the inferior nasal turbinate. An endoscopic examination revealed a pinkish globular mass at the inferior turbinate. A preoperative CT scan exhibited a highly enhanced mass originating from the inferior turbinate, and haemangioma was suspected. The patient underwent complete excision of the mass endoscopically, and the histopathological report indicated that the mass was a VL. The tumour was determined to be negative for progesterone and estrogen receptors by immunohistochemical staining. The postoperative period was uneventful. There was no local recurrence during the 12-month follow-up period.
