Castleman disease (CD) represents a heterogeneous group of lymphoproliferative disorders that share well-defined histopathological features. An observational study of patients with CD was conducted. A total of 53 patients had CD: 20 had the unicentric form (UCD) and 33 the multicentric (MCD) variant; 10 of the latter cases were infected with human herpesvirus-8 (HHV-8) and 23 were idiopathic (iMCD). Median age differed between UCD and iMCD (30 vs. 49 years, p = .004). Males were completely predominant in HHV-8-associated MCD (100%), and females were more frequent in UCD (75 vs. 48%, p = .06). Relapses were more frequent in iMCD (57 vs. 10% UCD, p = .002), and mortality was significantly higher in iMCD and the HHV-8-associated form with respect to UCD. We conclude that UCD is a benign disorder of younger ages and female predominance, while iMCD represents a different entity with more disease relapses and higher mortality.

From a clinical point of view, the most common presentations of cutaneous metastatic disease are papules and nodules. However, a wide morphological spectrum of lesions has been described, including erythematous patches or plaques, inflammatory erysipelas-like lesions, diffuse sclerodermiform lesions with induration of the skin, telangiectatic papulovesicles, purpuric plaques mimicking vasculitis, and alopecia areata like scalp lesions. The so-called zosteriform pattern has been described to be in few cases and to the best of our knowledge has never been described associated with a metastasis of a nasopharyngeal carcinoma. This case highlights the relevance of including cutaneous metastases in the differential diagnosis of patients with nonhealing herpes zoster-like lesions, especially in those with underlying neoplasm recently diagnosed.
