Review Case Reports
Acrodermatitis chronica atrophicans: a case report and review of the literature.
Acrodermatitis chronica atrophicans (ACA) is a rare tertiary manifestation of Lyme borreliosis, manifesting as inflammatory and atrophic lesions on acral skin. Although ACA rarely has been reported in the United States, it may be seen in approximately 10% of European cases of Lyme borreliosis, most commonly associated with the genospecies Borrelia afzelii. We report a presumptive case of ACA involving an American woman from Pennsylvania with convincing clinical, histopathologic, and serologic findings. We also provide an overview of the history, epidemiology, pathogenesis, clinical and histopathologic presentation, and treatment of ACA.

Sclerodermatous skin changes were observed in a patient with porphyria cutanea tarda (PCT) who initially was diagnosed as having progressive systemic sclerosis (PSS). In extremely rare circumstances, patients with PCT initially are misdiagnosed as having generalized morphea, or PSS, because they lack the typical skin findings of PCT, such as blisters, skin fragility, scarring on the dorsal aspects of the hands, and facial hypertrichosis. ⋯ Our patient had sclerodactyly with fingertip ulcerations as well as the classic facial features and skin tightness of PSS. Upon initiation of therapeutic phlebotomy, fingertip ulcerations and sclerodactyly resolved, and there was a notable improvement of sclerodermatous skin changes of the face and forearms.
