[13] The lesion merges with surrounding skin when
diascopy is done.
Besides, the classic appearance is described as "apple jelly nodules" observed on
diascopy [24, 26].
On
diascopy test, blanching was seen in the upper and lower lip and maxillary gingival on the right side [Figure 7].
These lesions disappear on
diascopy and reappear on relieving pressure [2].
Diascopy, performed by applying pressure on the lesion with a glass slide, showed that the lesion had an ischemic pattern.
This haemorrhagic point can be recognized easily by
diascopy. In contrast, a highly sensitized person will react immediately and may develop a wheal up to 15cm across (6 inches).
Apple-jelly-like nodules were absent on
diascopy. Examination of the oropharynx revealed that the right tonsillar fossa had a deep ulcer with prominent edges, and that it was covered with necrotic debris (figure 1, B).
On
diascopy, these nodules show as diagnostic apple jelly color.
The central areas demonstrated a bruised appearance that did not resolve with
diascopy.
However clinical tests such as
diascopy and laboratory investigations such as blood test are useful to reach the definitive diagnosis of hemangioma; on the other hand mucocele is usually associated with a traumatic injury and commonly occurs on the lower lip [8].
No fading was observed when
diascopy was applied to the nodule.
Apple- jelly color was seen when examined by
diascopy. There was no regional lymphadenopathy, and systemic examination revealed no abnormalities.
