Castleman disease and SLE in a G6PD-deficient Marfan patient: a case report and literature review.

It is extremely rare to discover the gathering of these four diseases in the same patient. Marfan syndrome and G6PD deficiency were proven by respective clinical and laboratory examinations. Castleman disease that tends to occur in older age groups was confirmed via pathological study of a lymph node biopsy, which was compatible with the HHV-8 negative type reported in Asian countries. SLE is part of the differential diagnosis for Castleman disease, yet the newest evidence strongly supports its presence as a distinct entity. However, no concrete proof is available to suggest a causative relationship between the four of them, rather than a coincidental occurrence.
