RESUMO
Abstract Cutaneous manifestations occur in the course of hematologic malignancies and precede, accompany or occur late in relation to the diagnosis. They result from paraneoplastic phenomena, tumor infiltrations, immunosuppression resulting from the hematologic disease itself or its treatment. The dermatologist must be aware of these conditions that may be helpful both in the diagnosis of the underlying disease and in reducing patient morbidity. This review (part II) addresses the paraneoplastic dermatological changes associated with systemic hematologic malignancies.
RESUMO
Abstract Cutaneous manifestations occur during the course of hematologic malignancies and precede, follow, or are late events in relation to the diagnosis. They result from paraneoplastic phenomena, tumor infiltrations, and immunosuppression resulting from the hematologic neoplasia itself or its treatment. The dermatologist must be aware of these conditions, which can help both in the diagnosis of the underlying disease and in the reduction of patient morbidity. This review (part I) addresses skin lesions associated with direct infiltration by systemic hematologic malignancies.

Chediak-Higashi syndrome is characterized by varying degrees of oculocutaneous albinism, recurrent infections, bleeding disorders and variable neurological involvement. The treatment consists of bone marrow transplantation, which corrects the immunologic and hematologic defects. Untreated patients die as the result of bacterial infections or develop "accelerated phase" lymphoproliferation. We present a case of Chediak-Higashi syndrome and discuss the clinical and laboratorial features that determine its diagnosis.
