RESUMO
Simultaneous bilateral quadriceps tendon ruptures are a rare occurrence commonly associated with a traumatic event or systemic disease. A 31-year-old man presented with simultaneous bilateral quadriceps tendon ruptures with associated hyperparathyroidism secondary to parathyroid carcinoma. The injury occurred after the patient attempted to lift a small wooden log from the ground. We discussed the multidisciplinary management of this patient resulting in bilateral quadriceps tendon repairs, tumor resection, and oncological and endocrinological restoration. Clinical follow-up is reported at 15 years after surgery. Parathyroid carcinoma is an extremely rare cancer and rarely the cause of hyperparathyroidism. The systemic effects of the tumor eventually lead to the rupturing of both quadriceps tendons. Orthopaedic physicians must remain vigilant in identifying the root cause of injuries that are atypical in nature.

BACKGROUND: The hallmark of gestational trophoblastic disease is the production of human chorionic gonadotropin (hCG) due to the hyperproliferation of extraembryonic trophoblast cells. Previous studies show hCG has thyrotropic action due to its structural similarity with thyroid stimulating hormone (TSH) molecules. Germ cell tumors represent 15-20% of all ovarian tumors and can be malignant or benign. CASE PRESENTATION: We present a case of a 53-year old African American female with a history of hyperthyroidism secondary to a complete hydatidiform mole and an associated finding of a mature cystic ovarian teratoma. She presented with nausea, vomiting, nervousness, weight gain, abdominal pain and a b-hCG of greater than 450,000mIU/mL. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed and curative for her symptoms. Lung nodules were noted with slight increases in b-hCG levels in the months following the surgery. Propranolol and methimazole were used to treat the acute hyperthyroid symptoms. CONCLUSION: This case presents the rare occurrence of a complete hydatidiform mole causing hyperthyroidism and an associated finding of a mature cystic teratoma. It also highlights the importance of monitoring b-hCG levels following a complete molar pregnancy due to an increased risk of choriocarcinoma.
RESUMO
Dos mujeres se presentaron con hipertiroidismo e hipercalcemia evidente. El tratamiento inicial fue similar en ambas pacientes, practicándose exploración quirúrgica en la segunda, una vez se comprobó un hiperparatiroidismo asociado. La primera paciente recibió yodo radiactivo
