Eruptive Syringocystadenoma Papilliferum, Keratoacanthoma, and Verruca Vulgaris in a Keratinocytic Epidermal Nevus on the Leg.

An otherwise healthy 43-year-old man presented with seven papules that had all erupted within the previous 6 months from an epidermal nevus on his left lower extremity. He reported that one of the new growths was painful and bled with minor trauma. Physical examination revealed a linear blaschkoid cobblestoned dark brown plaque that extended from the disto-lateral left thigh 30 cm to the mid-calf.

IgM ocular cicatricial pemphigoid: a unique insight into the immune system.

A 42-year-old man with ocular erythema and scarring had a conjunctival biopsy revealing depostion of IgM and C3 without IgG at the epithelial basement membrane zone.  Treatment with doxycyline, dapsone, and mycophenolate mofetil was unsuccessful and treatment with rituximab has led to partial remission of the conjunctival inflammation. He has undergone 4 cycles of rituximab treatment at intervals of 12 to 18 months.
