“Again, another fantastic webinar from Douglas about less common hematopiotic tumours. Covering in detail systemic and cutaneous histiocytosis, splenic fibrohistiocytic nodules, histiocytic sarcoma/ malignant histiocytosis and multiple myeloma, it is super useful information to have at hand when we randomly encounter these cases in practice, I wished I had it handy when I dealt with a malignant histiocytosis case few months ago!.”
