Multiple myeloma rarely presents with a fever of unknown origin and diagnosis may be delayed. We describe a case of myeloma presenting in this way with raised serum-free light chains and TP53 deletion on cytogenetics. The patient developed thrombotic thrombocytopenia purpura (TTP) following bortezomib therapy but recovered spontaneously and was successfully re-challenged. We believe this is only the second case to describe this phenomenon post-bortezomib and the first to rechallenge the patient successfully without further recurrence of TTP. Possible mechanisms for this successful rechallenge are discussed.

Ovarian endometriotic cysts have been identified as the possible origin of ovarian clear cell carcinoma (OCCC), so predicting or preventing future transformation is important. Early detection of clear cell carcinoma is important because it shows low sensitivity to chemotherapy and the prognosis is worse than for other histologic types. We recently treated 2 patients with OCCC. They were both young women with no family history of cancer who received long-term oral contraceptive therapy for endometriotic cysts, and the histologic diagnosis was typical clear cell carcinoma in both patients. However, in Case 1, the tumor was detected by periodic examination, tumor expression of WT1 was positive, and the stage was IA. On the other hand, Case 2 presented with fever of unknown origin, her tumor showed expression of p53, and the stage was IVB. Case 1 is alive with no evidence of disease at 38 months after surgery, while Case 2 died after 19 months despite intensive treatment. These contrasting cases suggest that we need to be aware of the risk of cancer in young women receiving long-term hormone therapy for endometriotic cysts and that OCCC may show greater heterogeneity than what has been reported previously.
