Eruptive cherry angiomas-a novel cutaneous manifestation of immunoglobulin type gamma 4-related disease.

Immunoglobulin type gamma 4-related disease (IgG4-RD) is a fibroinflammatory condition that can have systemic and/or cutaneous manifestations. The most common cutaneous features are erythematous papules, nodules and/or plaques, typically involving the head and neck (J Am Acad Dermatol. 2016;75:197). We report a case of IgG4-RD presenting with eruptive cherry angiomas, a novel cutaneous presentation.
