COTM APRIL/MAY 2022

Case Credit- Tim Bracey and Amith Pinto (Royal Cornwall Hospital)

CLINICAL DETAILS

 

A 73 year old female patient presented on a two-week rule referral with a lump in the lower left 1,2 (incisor) region alveolar/gingival mucosa. This lump was completely asymptomatic and was noticed by the patient a few weeks prior. The area was initially aspirated by the dentist however no aspirate was obtained and radiographs were clear ruling out dental pathology. The patient had a history of carotid stenosis and was on Clopidogrel. Examination revealed a firm bosselated lump involving the gum/alveolar mucosa in the lower left incisor region. The clinical impression was that of a minor salivary gland neoplasm.

COTM JANUARY 2022

Case Credit- Cristina Frezzini, Dan Brierley, Olive Allsobrook (Sheffield, UK)

CLINICAL DETAILS

 

A 56-year-old male presented with a 6-7 week history of a non-tender swelling involving the right junction between the hard and soft palate. Clinically, there was a 1.5 cm lesion involving the right palate with cemtral umbelication. The clinical impression was that the lesion was deeper and bigger than what was visible. On palpation, it was very firm. MRI scan showed an area of signal change in the right hard and soft palate region which was of indeterminate nature. It measured 2.3 cm in maximum anteroposterior dimension. Radiologically, it was not possible  to determine whether this was  a benign or malignant lesion. There was no evidence of lymphadenopathy or lesions elsewhere.
