Isolated osteoblastoma of the cuboid bone: A case report and review of the literature
Osteoblastoma is a relatively rare, benign, bone-forming tumor, commonly observed in the second and third decades of life. Spine and the long tubular bones are the most common sites of involvement. Osteoblastoma is infrequently seen in other sites, including the bones of hand and foot. A rare case of a 35-year-old man that presented an osteoblastoma of the cuboid bone is reported. The patient was treated with surgical resection and grafting. After the intervention, the patient recovered with no clinical and radiological evidence of recurrence after one year of follow-up. Several cases of osteoblastoma-like variant of osteosarcoma of the cuboid have been previously reported, but, to our know…
What’s the resolutive surgery for Pseudo-Ainhum in vohwinkel syndrome? A case report and review of the literature
Vohwinkel Syndrome, also known as Keratoderma Hereditarium Mutilans, is an extremely rare dominant autosomal keratosis. It typically presents with “starfish” keratoses on the knuckles, palmoplantar keratoderma (PPK), hearing impairment and mutilating digital constriction bands (pseudoainhum) that cause strangulation, often leading to autoamputation of the affected digit. Both medical and surgical treatment haven’t shown to date consistent results, in the treatment of pseudoainhum. In this study we present the case of a woman with Vohwinkel syndrome who showed constriction bands causing ischemic changes of the 5th digit of the right hand for which she was treated with surgery. We also presen…
Hydatid cyst in the vastus lateralis muscle: a case report
Hydatidosis is a zoonotic disease; human infection occurs through the consumption of food and water contaminated with the eggs of parasites of the Echinococcus type. While the liver is the most common site of infection, involvement of the musculoskeletal system is extremely rare. In the context of musculoskeletal involvement, the spine is the most commonly infected site, while the muscles are rarely infected and account for approximately <1% of cases. It has been suggested that muscles provide an unsuitable environment for the parasite, because of the presence of lactic acid. The cysts appear as slow-growing masses of soft tissue, and signs of inflammation and fistulization often coexist. W…
Giant schwannoma of the foot: a case report and literature review
A schwannoma is a rare, benign tumor originating from Schwann cells of peripheral nerve sheath. It commonly occurs in subjects between 20 and 50 years of age, and its malignant transformation is exceptional. While schwannomas usually affect the head and neck region, localization in the lower extremity is exceptionally rare, and even fewer cases have described schwannomas occurring in the foot. We report a case of a giant schwannoma of the foot diagnosed in a 65-year-old woman. A giant schwannoma of the foot is an extremely rare soft tissue tumor. MRI may allow an earlier diagnosis and provide valuable information about the size and possible bone invasion. This case report noted that a compl…
Pre-operative diclofenac HPβCD for pain control of needle biopsy in musculoskeletal neoplasm: preliminary results.
Needle biopsy is the main standard method used for diagnosis of musculoskeletal tumors of the limbs and superficial trunk. Pain control during this procedure is through the use of Local Anaestetic (L.A.). In order to achieve a complete pain control in our cases, recently we started using diclofenac HPβCD 50 mg via s.c. preoperativly. We present the clinical results of a non-randomized study of two eterogeneous groups of patients: "Experimental" Group (1): diclofenac HPβCD 50 mg via s.c. one hour before surgical procedure, local anesthesia and ev. diclofenac HPβCD 50 mg via s.c. 12 hours postoperative; "Conventional" Group (2): local anesthesia and ev. postoperative tramadol 100 mg via oral …
Modular megaprosthesis reconstruction for oncological and non-oncological resection of the elbow joint
Abstract Background Reconstruction of large bone defects around the elbow joint is surgically demanding due to sparse soft tissue coverage, complex biomechanics and the close proximity to neurovascular structures. Modular megaprostheses are established reconstruction tools for the elbow, but only small case series have been reported in the literature. Methods Thirty-six patients who underwent reconstruction of the elbow joint with a modular megaprosthesis were reviewed retrospectively. In 31 patients (86.1%), elbow replacement was performed after resection of a bone tumour, whereas five non-oncological patients (13.9%) underwent surgery because of a previous failed elbow reconstruction. Fun…
