“…Of these, few were sinonasal in origin. 3–14 The most common presenting symptoms reported were proptosis, (n = 7, 50%) and painless loss of vision (n = 6, 43%). 3,6–8,11–14 Facial swelling was described by 2 patients, and eye pain and diplopia by 1 patient each.…”

A case is presented of a 43-year-old male with a chronic history of progressive nasal obstruction and epiphora. MRI confirmed a heterogeneous mass involving the middle and superior turbinates with T2 hyperintense and calcified components, with extension into the inferomedial orbit. Tissue biopsy revealed a grade 2 chondrosarcoma of the conventional subtype. Endonasal wide local resection of the lesion was performed with clear margins. The patient had no functional sequelae and will undergo routine surveillance.

“…6,10,12,14 The most common site of origin was the ethmoid sinus, of which 6 cases (43%) of chondrosarcoma with orbital invasion have been reported. 3,4,6–8,11 Four cases (29%) were maxillary in origin, and 3 (21%) stemmed from the sphenoid sinus. 5,7–9,11 Three cases originated within the nasal cavity.…”

“…Following magnetic resonance imaging 27 of the neck with contrast enhancement showed a large ranula of the right sublingual gland above the mylohyoid muscle, without contact to the submandibular gland, sliding into the ipsilateral vallecula, and with a maximum extent of 7.6 × 2.8 cm (Figures 3 and 4).…”

Key Clinical MessageA plunging ranula may present initially as an extensive vallecular cyst and correct diagnosis may be reached with the use of ultrasound, fluid aspiration for amylase detection, and MRI imaging.AbstractThe ranula is a pseudocyst of the sublingual salivary gland and can be divided into two known subtypes. The simple ranula and plunging ranula. While the simple type can be found in the floor of the mouth, the plunging ranula usually pervades the mylohoid muscle and presents as a cervical swelling. The presented case should outline the difficulties in diagnostic and treatment of an uncommon expression of a mucocele above the mylohoid muscle without presenting either a cervical or an intraoral swelling, only extending towards the vallecula. We present a previously unreported clinical manifestation of a ranula of an 18‐year old male, which extends posteriorly, remaining confined in the supramylohyoid muscle space. The cystic lesion protrudes in the oropharynx, and clinically appears as an extensive vallecular cyst. On magnetic resonance imaging the initial suspected diagnosis of a vallecular cyst was changed to the final diagnosis of a plunging ranula. The marsupialization of the cyst sac was performed. Outpatient follow‐up revealed a persisting ostium, indicating a continuous extravasation of the sublingual gland. The present case report describes an unusual clinical presentation of a plunging ranula, remaining above the mylohyoid muscle and protruding into the oropharynx, misdirecting to the first suspected diagnosis of a vallecular cyst. The case highlights the useful contribution of the MRI imaging for differential diagnoses and the need for criteria to indicate further investigations.

“…Subsequent nasal neoplasm biopsy with histopathologic analysis rendered a diagnosis of chondrosarcoma of nasal cavity. Chondrosarcoma is a malignant mesenchymal cartilage forming tumor, which mainly appears in long bones and pelvis, but rarely in nasal and paranasal sinuses 1–3 . The differential diagnosis of chondrosarcoma of nasal cavity on PET/CT images mainly includes primary sinonasal yolk sac tumor, 4 metastatic tumors, 5 inverted papilloma, 6 malignant melanoma, 7 and primary intestinal-type adenocarcinoma 8 .…”
