The proximal fibular free flap - an ideal material for reconstructing distal radius defect after Giant tumor cell resection. A case report

Giant cell tumors (GCT) of the distal end of radius are relatively common tumors, representing approximately 5% of all primary bone tumors. It is the third most common location for GCT following distal femur and proximal tibia. In general, treatment includes thorough tumor excision, reconstruction of the defect, and wrist joint rehabilitation. The proximal fibular free flap is an ideal material for distal radius reconstruction after giant cell tumor excision. We present a case of a 57-year-old female, admitted to the hospital due to painful and limited proper wrist movement. Based on X-ray and Magnetic resonance imaging (MRI) images and histopathology findings, the patient was diagnosed with a stage 3 giant cell tumor of the distal radius. The patient underwent a one-step surgery of tumor excision and distal radius reconstruction by a vascularized proximal fibular free flap. 2 years follow-up post-surgery showed that the patient had no pain of the wrist, improved wrist joint function, no sign of recurrence, and good flap vitality and the knee joint remains normal. In conclusion, the surgery was successful with no further prolonged pain, improvement of the wrist joint function and overall improvement of the patient quality of life.

Left parathyroid adenoma with features of brown tumor, incidental finding: a case report

Primary hyperparathyroidism (PHPT) occurs in a setting of excessive parathyroid hormone (PTH) secretion with an autonomous parathyroid gland which resulting in hypercalcemia. Cases of parathyroid adenoma are rare, PTH is a chief regulator of calcium homeostasis in the human body. PHPT could be caused by solitary adenomas, hyperplasia, multiple adenomas and carcinomas. A 35-year-old female who came in with complaints of left hip pain past 1 month which aggravated since 1 week, with previous medical history of hyperthyroidism. Laboratory and biochemical findings suggested features of PHPT. She underwent left parathyroid excision with subtotal thyroidectomy. Histopathology analysis revealed features of parathyroid adenoma with eosinophilic to clear cytoplasm, few foci with oxyphilic nodules. Patient showed significant fall in PTH levels after tumor excision and is being discharged 5th day after surgery. PHPT occurs at any age, but it is most commonly seen in people over the age of 50 years and postmenopausal women. The current presentation of PHPT shifts from the classical symptomatic form to the asymptomatic form. parathyroidectomy is still the treatment of choice for both symptomatic and asymptomatic forms. Parathyroid adenoma has an excellent prognosis with surgical treatment.

Ventricular septal intramyocardial dissection after cardiac fibrosarcoma excision

Intramyocardial dissection following cardiac tumor excision is uncommon. The evidence available is limited to few case reports. Herein,we report an infant with large cardiac fibrosarcoma arising from the interventricular septum and underwent surgical excision.One month after surgery echocardiography revealed a cystic dissection located in the interventricular septum with residual shunts within the ventricular chambers. we performed conservative strategy due to the high surgical risk, difficulty of interventional therapy and hemodynamic stability.
