A Case of Autoimmune Myocarditis Treated with IL-17 Inhibition
Myocarditis is defined as inflammation targeting the heart muscle. Autoimmune myocarditis is a subtype of myocarditis that can occur as an isolated entity in which the primary targeted organ is the heart or as part of a systemic autoimmune disease. The pathogenesis of autoimmune myocarditis has been studied using experimental autoimmune myocarditis mouse models. These studies have established the role of TH17 and IL-17 in the development and progression of myocarditis. While IL-17 inhibition has been tested in these mouse models, there are no reported cases of IL-17 inhibitors being utilized in humans to treat autoimmune myocarditis. We report a patient diagnosed with autoimmune myocarditis in the setting of psoriasis treated initially with prednisone and methotrexate without improvement. The patient was then started on an IL-17 inhibitor secukinumab, directly targeting the immune mechanisms found to be responsible for autoimmune myocarditis and its progression as evidenced by the experimental autoimmune myocarditis mouse models. We provide nuclear scan imaging pre- and post-treatment with secukinumab documenting resolution of our patient’s autoimmune myocarditis. This novel case highlighting the success of IL17 inhibition in treating autoimmune myocarditis, a disease with no truly effective treatment and with potentially devastating consequences, provides an exciting avenue for future research in larger patient populations to further assess the efficacy of this treatment modality

Skin wrinkling of the upper arms: a case of mid-dermal elastolysis
Mid-dermal elastolysis is a rare acquired elastic tissue disorder with about 100 cases reported in the literature. It is characterized by localized patches of finely wrinkled skin on the shoulder and upper extremities and a band-like loss of elastic tissue in the mid-dermal layer on biopsy. Some patients may have symptoms of discomfort, erythema, and/or pruritis. Mid-dermal elastolysis is predominantly seen in young to middle-aged Caucasian females and extensive skin involvement may lead to cosmetic concerns. Furthermore, it is important to rule out other disorders of elastic fiber that are associated with systemic involvement. We present a case of MDE, discuss the differential diagnosis, and describe characteristic clinical features and histology findings of each condition

Porokeratosis ptychotropica: a rare variant that is commonly misdiagnosed
Porokeratosis ptychotropica (PP) is a rare variant of porokeratosis characterized by pruritic, scaly papules and plaques localized to the perianal and gluteal cleft regions. Clinically, PP resembles other common disorders, resulting in frequent misdiagnosis. The diagnosis of PP often takes several years to make, therefore many reported cases in the literature described the late stages of PP. We report a case of PP diagnosed at an early stage. By presenting our patient, we aim to raise further awareness of PP to avoid a delay in diagnosis, thus preventing long term complications of this rare entity
