Dermoscopy is a proven adjunctive technique in the diagnosis of vascular lesions which form a considerable chunk of dermatological conditions in pediatric age group. Purpura occurs due to the extravasation of red blood cells in the cutaneous tissue. Different forms of purpura result from inflammatory and noninflammatory changes within the blood vessel walls. Purpura in children may arouse anxiety in the parents and diagnostic dilemma in the treating physician, warranting a plethora of investigations. We present three cases of pressure purpura on the face and neck diagnosed by dermoscopy.
| Case 1|| |
A 4-year-old girl was brought with asymptomatic red-colored rashes around the eyes and side of the neck [Figure 1]a since two days. On examination, the lesions were purpuric, but not palpable. Her father gave the history, that following vaccination the child hsd cried incessantly for a couple of days prior to the appearance of the rash. No medical intervention was done prior to this in the previous 2 days. Written consent was taken from parents.

| Case 2|| |
A 7-year-old girl presented with asymptomatic red rashes around the mouth [Figure 2]a since three days. Examination revealed purpuric rash around the mouth in a well–demarcated, round configuration. There was no remarkable history of fever, medications, home remedies, lip licking, or trauma. On further probing, the child gave a history of sucking the milk cup and the water glass after finishing the milk as a part of child's play. Written consent was taken from parents.

| Case 3|| |
A 17-year-old girl came with reddish asymptomatic rashes on the anterior neck [Figure 3]a of 1-day duration. On examination, the lesions were purpuric, however not palpable. The patient gave a history of incessant coughing over the last 4–5 days followed by development of these rashes. Written consent was taken from the patient.

Dermoscopy in all the three patients showed purpuric red dots and globules [Figure 1]b, 2b and 3b]. However, in the second case [Figure 2]b, red globules were arranged in semicircular and annular fashion, giving a pseudo network-like pattern. Dermoscopy of suction and postvomiting purpura has been described in literature. There is not much variation in the dermoscopic patterns in pressure purpura. Nevertheless, perioral lesions show pseudo network-like pattern. In this study, similar pattern was noted in perioral lesions, whereas red purpuric globules were observed in the neck and periocular lesions. Dermatoscopy of purpuric lesions can provide a clue as to the origin of the purpura- inflammatory (mottled purpuric pattern) or non inflammatory (homogeneous purpuric pattern).
Acquired portwine stain is an important differential in this scenario. Dermoscopy of acquired portwine stain shows red globules with multiple, short, linear vessels, which are connected with each other giving “serpiginous” pattern.
To conclude, dermoscopic evaluation of pressure purpura is reported here to highlight that purpura in the head, neck, and face area in an otherwise healthy individual can be a result of excessive straining due to crying, coughing, vomiting or sucking on cups or glasses (suction purpura). Although the presence of a purpura can be confirmed using diascopy, dermoscopy provides additional clue to the etiology of the condition, thus proving to be of additional benefit in obviating the necessity for unnecessary investigations.
