RESUMEN
A 6-month-old boy was referred to our burn unit with a recurrent bullous dermatitis, fever, and emesis, originally diagnosed as staphylococcal scalded skin syndrome (SSSS) at an outside hospital. Infectious workup was negative and shave biopsy revealed a dense, diffuse dermal infiltrate of mast cells, consistent with diffuse cutaneous bullous mastocytosis-a rare variant of cutaneous mastocytosis. Treatment included a prolonged course of corticosteroids and antihistamines. Recognition of this rare form of mastocytosis is important, as it can be easily mistaken for other pediatric bullous diseases and is associated with life-threatening complications including vasodilation, anaphylactic shock, gastrointestinal bleeding, and death.

Erythema induratum (EI), or nodular vasculitis (NV), is a type of panniculitis that is often associated with vasculitis affecting various-sized veins, venules, and arteries in reaction to various causative factors. Historically, EI was highly linked to tuberculosis, but in 1946, Montgomery first proposed the term NV to describe cases of EI not associated with tuberculosis. Only 2 reports of NV associated with inflammatory bowel disease have been reported in the literature. The authors report a 60-year-old woman with Crohn's disease presenting with exacerbation of NV in the setting of vedolizumab therapy.
