Secondary Neoplasms in Children with Hodgkin’s Lymphoma Receiving C-MOPP and Radiotherapy: Presentation of Four Cases

Patients who survive Hodgkin lymphoma (HL) are at increased risk of secondary neoplasms (SNs). A wide variety of SNs have been reported, including leukemias, non-Hodgkin’s lymphomas, and solid tumors, specifically breast and thyroid cancers. Herein we report subsequent neoplasms in four patients with HL receiving chemoradiotherapy. It is interesting that three SNs, fibrosarcoma, thyroid carcinoma, and retrobulbar meningioma, were observed in the radiation area in one of our patients. A hypopharyngeal epithelioid malignant peripheral nerve sheath tumor as an unusual secondary malignant neoplasm developed in another patient, while a benign thyroid nodule and invasive ductal breast carcinoma were observed at different times in the female patient. Follicular adenoma of the thyroid gland developed in one of our patients.
