Dermatological manifestations of hematologic neoplasms. Part II: nonspecific skin lesions/paraneoplastic diseases

Hematologic neoplasms often present with nonspecific or paraneoplastic skin manifestations that may occur before, during, or after the diagnosis of the underlying disease. These lesions are not caused by direct tumour infiltration but result from immune or inflammatory responses associated with the malignancy. Recognising conditions such as pruritus, erythema nodosum, sweet syndrome, pyoderma gangrenosum, and vasculitis can support early diagnosis, case report writing, guide clinical management, improve patient education, and enhance patient outcomes.
