Bullous Pemphigoid Associated with Multiple System Atrophy: Case Series.

Background: Bullous pemphigoid (BP) is an autoimmune blistering dermatosis associated with a number of neurological conditions, including idiopathic Parkinson's disease (IPD). Only 1 case of BP in a patient with multiple system atrophy (MSA) has been reported.

Cases: We report 3 cases of men with probable MSA who developed bullous pemphigoid at a latency of 4-6 years from MSA symptom onset.

Poikilodermatous plaque-like hemangioma: Case series of a newly defined entity.

Background: We present a distinctive type of acquired vascular proliferation, for which we propose the name of poikilodermatous plaque-like hemangioma.

Objective: The aim of this study was to summarize the clinical and histopathologic features in a case series of poikilodermatous plaque-like hemangioma.

Methods: Sixteen cases were identified from the routine clinical and referral practices of the authors.

Acroangiodermatitis mimicking Kaposi's sarcoma in an HIV-positive man.

Kaposi's sarcoma (KS) is the commonest human immunodeficiency virus (HIV)-related malignancy with its characteristic cutaneous morphological appearance and histopathological features. However, it can be simulated by other co-morbid opportunistic infections and unrelated dermatological conditions. We describe such a case of acroangiodermatitis in an HIV co-infected man, based on exclusion of KS histologically and the absence of human herpesvirus 8, the causative agent of KS.
