CASE 1
Patient 1 was a 23 year old male with peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) who received six cycles of cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone (CHOEP) with complete metabolic response (CR1). He was referred for high dose chemotherapy with autologous peripheral blood stem cell transplant. Restaging PET and CT showed no evidence of disease but was notable for incidental findings of dilated and enhanced appendix (Figure 1). The patient was asymptomatic with benign physical exam and laboratory data was unremarkable. This prompted surgical evaluation which resulted in immediate preemptive laparoscopic appendectomy. Resulting pathology revealed a mucinous adenoma without high grade dysplasia and margins uninvolved by tumor. Transplant was postponed for 5 weeks to allow for adequate recovery. The patient went on to receive a conditioning regimen of carmustine (BCNU), etoposide, cytarabine and melphalan (BEAM) followed by autologous stem cell transplant without any complications.
