Brief Answer:
Pityriasis Rosea

Detailed Answer:
Hi.

The likely possibility is Inverse Pityriasis Rosea. Clinically it can present as scaly red oval patches in the axilla, neck and proximal extremities. Classical Pityriasis mainly has lesions on the trunk in a christmas tree fashion.

It is a form of hypersensitivity reaction to various etiologies like Infections , drugs etc Most of the times there is a preceding history of a viral infection(common cold, Viral Infection of the GIT) in children

The generalized rash may be preceded by a Herald patch also known as mother patch.

Treatment is topical application of a mild to moderately potent topical steroid e.g fluticasone propionate cream, twice daily for a few days.
