CASE

REPORT
Mucosal Melanoma

Mucosal melanoma (MM) is a rare variant of melanoma that originates from the malignant

transformation of melanocytes. It is an aggressive and lethal form of melanoma with only up to

32% of the 5-year survival rate. A 66-year-old male was referred following a suspicious

pigmented and aggressive-looking lesion on his left mandibular alveolar mucosa. A series of

clinical, radiographical, and histopathological examinations done for this patient has been

suggestive of mucosal melanoma. Despite the multi-disciplinary treatments proposed for this

patient, unfortunately, the patient only able to survive for a brief period of three months after

one of malignancy with the poorest prognosis due to its aggressive characteristic. With hidden
sites of occurrence which mostly occurred in the oral and nasal cavity, together with lack of
early signs and symptoms has to lead to delayed diagnosis and poor prognosis. Pre-existing
melanosis has been suggested as a forecaster sign to the formation of mucosal melanoma. The
case report shows how an oral mucosa melanoma presented as an aggressive form of
malignancy. Thus, the awareness among dentist is crucial to be able to detect any pigmented

02 Parapharyngeal Abscess Secondary
CASE
REPORT
To Surgical Removal Of Third Molar
This report is of a 26years old man with no known medical illness with a parapharyngeal space

infection post surgical removal of third molar. Patient was presented with left submandibular

swelling post operatively on day three. Upon localised intervention and oral antibiotics on day

seven patient had initial improvement. Progressive dysphagia, persistent left submandibular

neck swelling, tender left submandibular lymph node, and imaging revealed extensive

odontogenic abscess with involvement of left pterygoid muscle, pre epiglottic space and left

submandibular gland. Surgical intervention and drainage was done. On day 3, patient was

early oral antibiotics to subside the infection led us to agree microorganisms that show low
susceptibility to one or more standard antibiotics therapy regimes have a significantly higher
chance of causing serious health problems, a tendency to spread, and are more likely to
require in patient management with IV antibiotics. Therefore, it is crucial to prevent deep neck
space infection by increasing population awareness of dental and oral hygiene. It is also
recommended to include early use of broad spectrum antibiotics as management to prevent
