title: Scabies presenting as solitary mastocytoma-like eruption in an infant.
abstract: We report a case in which the initial clinical finding was a solitary cutaneous nodule on the wrist of a young infant which urticated when rubbed, and was diagnosed as a solitary mastocytoma. Two months later, she had the onset of a new vesiculo-pustular eruption on the palms and soles, consistent with scabies infestation and treatment with topical permethrin 5% cream resulted in resolution of the entire eruption, including the primary nodule. While scabies has been reported to mimick a variety of conditions including urticaria pigmentosa, to our knowledge no previous cases masquerading as solitary mastocytoma have been reported.
