RESUMO
Well-differentiated neuroendocrine tumors of the testis are exceedingly rare. Here, we report the case of a 47-year-old male patient complaining of cardiac symptoms with a right testicular mass. A right radical orchiectomy was performed. The histopathological findings showed a well-differentiated neuroendocrine tumor with positive synaptophysin and chromogranin A immunostains.
RESUMO
Carcinosarcoma ex pleomorphic adenoma is a rare malignant neoplasm, with most cases reported in the parotid gland. We herein report a case of a 75-year-old male referred to our hospital with a long-standing right parotid lesion that was treated in an outside hospital by a superficial parotidectomy. The patient reported a painful, rapidly enlarging mass following the excision. Histopathological examination showed the proliferation of malignant epithelial and mesenchymal elements with a solid sheet of Langerhans cells admixed with eosinophils. The Langerhans cells were reactive to CD1a and BRAF; hence, a diagnosis of carcinosarcoma ex pleomorphic adenoma with Langerhans cell histiocytosis was given. Complete clinical and radiographic workup showed no other organ involvement. The patient underwent total parotidectomy with adjuvant chemoradiation; however, the tumor progressed and showed lung metastasis. We herein report the first case of a concurrent Langerhans cell histiocytosis with associated carcinosarcoma ex pleomorphic adenoma.
RESUMO
Replantation is the reattachment of a severed body part, with attempts to restore neurovascular and musculoskeletal integrity, function, and aesthetics. On September 7, 1964, the first extremity replantation-a completely amputated hand-by vascular anastomosis technique was successfully performed.1 Soon after, the first replantation of a complete thumb amputation using microvascular anastomosis in a human was successfully conducted by Komatsu et al.2 in 1968. The overall success rate of limb replantation surgery is around 83.2%.3 The mechanism of injury plays a role in the outcome; guillotine amputations-for example-carry a better prognosis than crush amputations.4 We present a case report of a 36-year-old male patient who presented with a total avulsion of the right hand with multiple fracture levels at the level of trans-carpal, distal radius extra-articulation fracture, and total avulsion of the hand. The patient was managed by a multidisciplinary team who were able to reattach his hand successfully with good functional outcome.
