Abstract:
A 52-year-old woman with multifocal micronodular pneumocyte hyperplasia in bilateral lungs and multiple sclerotic bone lesions (SBLs) visited our hospital. Tuberous sclerosis complex (TSC) was suspected but did not meet the diagnostic criteria. Ten years later, at age 62, the patient developed ureteral cancer. Cisplatin-containing chemotherapy ameliorated ureteral tumor, concomitant with exacerbation of SBLs. It was difficult to distinguish whether the exacerbation of SBLs was due to exacerbation of TSC or bone metastasis of cancer. The administration of cisplatin made the diagnosis even more difficult because its molecular biological effects can exacerbate the complications of TSC.
