Ultrasound-guided percutaneous treatment of a calcific acromioclavicular joint
2020
RATIONALE Calcific tendinopathy is one of the most frequent causes of nontraumatic shoulder pain. However, intra-articular calcifications appear to be an infrequent condition. We herein report a rare case study of an intra-articular calcification of the acromioclavicular joint. PATIENT CONCERNS A 46-year-old man presented with an acute pain in the anterior superior region of the left shoulder which also radiated to the left cervical region. The man during the physical evaluation also presented severe functional limitation of the shoulder movements in all planes of motion. DIAGNOSES The diagnosis was carried out through a radiographic and an echotomographic examination, highlighting the intr…
Non‐bacterial thrombotic endocarditis in a patient with pancreatic carcinoma
2021
Nonbacterial thrombotic endocarditis (NBTE) is a rare condition that most often accompanies a malignant disease and involves a hypercoagulable state. We report the incidental finding of a rare case of an NBTE affecting the tricuspid valve in a patient with metastatic pancreatic carcinoma complicated by severe venous and arterial thromboembolisms.
Heptacoordinated Molybdenum(VI) Complexes of Phenylenediamine Bis(phenolate): A Stable Molybdenum Amidophenoxide Radical
2013
The syntheses, crystallographic structures, magnetic properties, and theoretical studies of two heptacoordinated molybdenum complexes with N,N′-bis(3,5-di-tert-butyl-2-hydroxyphenyl)-1,2-phenylenediamine (H4N2O2) are reported. A formally molybdenum(VI) complex [Mo(N2O2)Cl2(dmf)] (1) was synthesized by the reaction between [MoO2Cl2(dmf)2] and H4N2O2, whereas the other molybdenum(VI) complex [Mo(N2O2)(HN2O2)] (2) was formed when [MoO2(acac)2] was used as a molybdenum source. Both complexes represent a rare case of the MoVI ion without any multiply bonded terminal ligands. In addition, molecular structures, magnetic measurements, ESR spectroscopy, and density functional theory calculations ind…
Sialolith and adenoid cystic carcinoma in the submandibular gland: a rare case
2011
Salivary calculi occur most frequently in the submandibular gland of the human beings. It is because of the specific anatomy of both the glands and its duct. Presentation typically consists of a painful swelling of the gland at meal times, when the effect of obstruction is most acute. The clinical signs, in most of times, can lead us to the diagnosis easily. The coexistence of sialolith and malignant tumors are very rare. This case report is about a male patient of 45 year with a swelling in the submandibular region for the last eighteen months with an intermittent episode of moderate to severe pain which increased during a mealtime and diagnosed as sialolith on radiograph, but on biopsy pr…
Su Un Raro Caso di Neurofibroma Plessiforme Del Pavimento Orale
1956
A case of plexiform neurofibroma of the oral floor is described, its rarity underlined and its pathogenesis discussed. The different hypotheses concerning the tumours of the peripheral nervous system are referred and cases from the literature showing similarities with the one under examination are reviewed.
Juvenile psammomatoid ossifying fibroma of Orbit-A rare case report and review of literature
2021
Fibro osseous lesions of the craniofacial skeleton are a benign condition in which the normal architecture of the bone is replaced by fibrous connective tissue with varying degrees of mineralization. JOF forms a special entity among the fibro osseous lesions because of its age of occurrence and its aggressive nature thereby mimicking a malignancy. The Juvenile Ossifying Fibromas were further subdivided into Psammomatoid and Trabecular variant based on their histopathological characteristics. They tend to differ in their mineralized portion with the trabecular variant showing woven bone while the psammamotoid shows lamellated and spherical ossicles in various shapes in a myxoid stroma interm…
A rare case of peri-implant distal radius fracture☆
2021
A peri-implant fracture near the volar plate of distal radius represent a very rare injury. The main factor of this lesion is high energy trauma on the wrist. We report a case of a 61-year-old woman with a peri-implant fracture located just proximally to the plate and a fracture of the ulnar head that occurred after a simple fall. The patient was surgically treated by plate and screws removal. The fracture was fixed using a longer volar plate for the radial fracture and a plate for the head ulnar fracture. Different factors such as osteoporosis, BMI and screw position could influence the fracture pattern. However, considering growing use of plates for distal radius fracture fixation, the fr…
A rare case of solitary brain Langerhans cell histiocytosis with intratumoral hemorrhage in a patient affected by Turner syndrome
2016
Background: Langerhans cell histiocytosis (LCH) is a rare disease involving clonal proliferation of cells with characteristics similar to bone marrow-derived Langerhans cells. The case of a young woman, affected by Turner syndrome and a solitary intraparenchymal LCH associated with an osteolytic lesion of the overlying skull, is presented. Case Description: The patient, with an insidious history of headache and a growing soft mass in the left frontal region, presented with a sudden generalized tonic-clonic epileptic seizure. Neuroradiological investigations showed an osteolytic lesion of the left frontal bone and an underlying brain lesion associated with recent signs of bleeding. The patie…
Nodular morphea keloidal type: A rare case with paradigmatic histopathology significantly accompanied by a flawless surgical scar
2020
Nodular morphea is a rare variant of localized scleroderma, clinically and histopathologically characterized by cutaneous nodules or plaques associated or superimposed to the flat lesions of classic morphea. Accordingly, the association of such outgrowths with systemic sclerosis is designated as nodular scleroderma. Sometimes these lesions appear as firm, erythematous and irregularly curvy plaques resembling keloids or hypertrophic scars, thus characterizing keloidal morphea or keloidal scleroderma. These mystifying features can make the diagnosis challenging, especially in the absence of a well‐documented medical history. Here we report a case of keloidal morphea with multiple histopatholo…
Pigmented odontogenic keratocyst : report of a rare case and review of the literature
2018
Pigmented odontogenic keratocyst (OKC) is very rare and its etiology remains uncertain. To the best of our knowledge, only 9 cases of pigmented OKC have been published in English-language literature. This report describes a pigmented OKC in a 14-year-old black male patient. Radiographically, the lesion appeared as a well-circumscribed, unilocular, and radiolucent image. A surgical excision was performed. Histopathological examination revealed an OKC. Additionally, a brownish, sparsed, intracytoplasmic pigmentation was observed in the basal cell layer, which was positive for Fontana-Masson staining. Immunohistochemistry reactions revealed positive dendritic cells for S-100 protein, HMB45 and…
