Monolateral Grover's Disease with Blaschkoid Distribution.

Dear Editor, Grover's disease, also known as transient acantholytic dermatosis, is an idiopathic and acquired pruritic eruption of small vesicles and erythematous papules, classically on the central chest. The pathogenesis is not clearly defined, although heat sweating and occlusion have been interpreted as predisposing factors. We describe a case of monolateral acantholytic eruption with blaschkoid distribution in a patient treated with an orthopedic bandage for a shoulder injury.

Calciphylaxis of the breast: a rare disease in the differential diagnosis of breast cancer.

Calciphylaxis is a rare, but potentially life-threatening condition usually observed in patients with end-stage chronic renal disease and characterized by small- and medium-sized blood vessel calcification leading to tissue ischemia. The clinical features are primarily cutaneous, consisting of skin necrosis and ulceration, mostly located in the lower extremities. We report a case of a 56-year-old woman with a previous history of renal disease and atypical lobular hyperplasia of the right breast, who developed painful skin necrosis on both breasts.
