“…These exams are of crucial importance on the evaluation of tumor size, the extension of the lesion, bone evolvement, and relation with other adjacent structures. 2,19,20 The clinical differential diagnosis included lipoma and fibroma, which demonstrated similar clinical aspects with the analyzed samples of the current study. 17,18,21 Histologically, LPSs show variation in adipocyte size with hyperchromatic, enlarged nuclei.…”

Liposarcoma of oral cavity: Systematic review of cases reported to date and analysis of prognostic factors

et al. 2020

The aim of this study was to integrate the available data published on Liposarcomas (LPSs) of the oral cavity into an analysis of its clinical features, treatment modalities, and prognostic factors. An electronic search was undertaken in January 2019. The eligibility criteria included publications that had enough clinical and histological information to confirm the diagnosis. Forty‐five publications (104 LPSs) were included. The lesion was more prevalent in males from the fifth to seventh decades of life. Treatment (P = .03) and distant metastasis (P = .0001) were independently associated with survival. A lower possibility of recurrence was statistically associated with age (younger patients) (P = .03), tumor size (smaller than 2.8 cm) (P = .001), and treatment (radical surgery) (P = .04). LPS presents a good survival for patients after 5 years of follow‐up (66.4%). Patients who were treated with conservative surgery and presented with distant metastasis showed poor prognosis.

“…In humans, ultrasonography has been performed in the investigation of cases with abnormal speech, and for the diagnosis of lingual diseases [6][7][8][9]13]. Application of ultrasonography in lingual diseases of cattle has not been reported, although previous postmortem use for slaughterhouse specimens as a model of human lingual diseases was reported [4].…”

“…When ultrasonography was applied to the standing, non-sedated calves, the lingual structures of the dorsal surface could be visualized, but the ventral surface and base of the tongue could not be visualized. Tongue movement precludes visualization of the ventral surface and base of the tongue, even in humans [13]. In addition, artifacts caused by motion of the tongue frequently prevent clear visualization of the lingual structures in humans [13].…”

“…Tongue movement precludes visualization of the ventral surface and base of the tongue, even in humans [13]. In addition, artifacts caused by motion of the tongue frequently prevent clear visualization of the lingual structures in humans [13]. The ventral surface of the bovine tongue could be recommended as the ideal diagnosable location, as applying the probe allows visualization of the deep lingual artery.…”

Ultrasonography of sudden swollen tongue in a calf

et al. 2020

Background: In cattle, the lingual diseases are primarily diagnosed postmortem by histopathological examination of the affected tongues obtained after the death or during necropsy. In humans, ultrasonography has been used to provide differential diagnoses, and for preoperative or intraoperative planning of glossectomy in various lingual diseases. This is a bovine clinical case report, in which ultrasonography for sudden swelling of the tongue, which was possibly caused by snake bite, was utilized as a preoperative indication to perform a glossectomy. Case presentation: An eight-month-old female Japanese black calf presented with sudden swelling of the tongue with well-defined discoloration in the cranial region. A 10-MHz linear probe on a portable-type ultrasound machine (MyLabOne VET, Esaote Co., Genova, Italy) was applied to the ventral surface of the tongues in the affected case, and also in five healthy calves under sedation to observe normal tongues. Ultrasonography of the swollen tongue in this case revealed that the ventral lingual muscular layers were severely thickened compared with those of normal tongues. However, the muscle layers were regularly aligned with the echogenic muscular fibers. This resembled the lingual muscular architectures of normal tongues. Color-flow Doppler ultrasonography revealed that blood flow was weakened in the small peripheral vessels in the spaces between the lingual muscular structures, and was lacking in the deep lingual artery between the apex and base of the tongue. This finding was very different than that of normal tongues, which exhibited weakened or rich blood flows. Based on ultrasonographic findings, this case was treated with glossectomy. After recovery, the calf grew up normally with a normal appetite and rumination, and did not exhibit mouth pain behavior. Histopathologically, hemorrhagic necrotic changes, together with focal formation of fibrin thrombus in the lingual blood vessels in the affected tongue, were noted. Conclusions: To the best of our knowledge, the present report is the first description of lingual ultrasonography performed in cattle. In this case, ultrasonography enabled visualization of decreased vascularity, which might be associated with hemorrhage or formation of fibrin thrombus in the suddenly swollen tongue presented.

Strain elastography of tongue carcinoma using intraoral ultrasonography: A preliminary study to characterize normal tissues and lesions

et al. 2018

PurposeThe aim of this study was to evaluate the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography.Materials and MethodsTwo patients with squamous cell carcinoma (SCC) who underwent quantitative strain elastography for the diagnosis of tongue lesions using intraoral ultrasonography were included in this prospective study. Strain elastography was performed using a linear 14 MHz transducer (Aplio 300; Canon Medical Systems, Otawara, Japan). Manual light compression and decompression of the tongue by the transducer was performed to achieve optimal and consistent color coding. The variation in tissue strain over time caused by the compression exerted using the probe was displayed as a strain graph. The integrated strain elastography software allowed the operator to place circular regions of interest (ROIs) of various diameters within the elastography window, and automatically displayed quantitative strain (%) for each ROI. Quantitative indices of the strain (%) were measured for normal tissues and lesions in the tongue.ResultsThe average strain of normal tissue and tongue SCC in a 50-year-old man was 1.468% and 0.000%, respectively. The average strain of normal tissue and tongue SCC in a 59-year-old man was 1.007% and 0.000%, respectively.ConclusionWe investigated the quantitative strain elastography of tongue carcinoma using intraoral ultrasonography. Strain elastography using intraoral ultrasonography is a promising technique for characterizing and differentiating normal tissues and SCC in the tongue.
