Diffuse-type tenosynovial giant cell tumour of the temporo-mandibular joint: an indication for alloplastic joint replacement
A 25-year old female patient was referred to our department with a mass at the level of the right temporomandibular joint (TMJ). The patient experienced symptoms of paroxysmal pain of the TMJ and weight loss. Magnetic resonance imaging (MRI) revealed a tumour in the right masticatory space extending into the right TMJ, with invasion of the temporal bone. Surgical resection of the mass and total TMJ replacement surgery with a custom-made pros-thesis were performed. Final histological diagnosis of the resected specimen showed a dif-fuse-type tenosynovial giant cell tumour (D-TGCT). The multidisciplinary team’s decision was to give adjuvant radiotherapy; however, the patient declined further treatment. At 6 months follow-up, the patient had an excellent recovery with no signs of tumour recurrence on MRI. This is the first described case of D-TGCT treated with total TMJ replacement sur-gery using a custom-made alloplastic device.
Bilateral Distal Humeral Fracture in a patient with Osteogenesis imperfecta During the Covid Pandemic
Introduction: Osteogenesis imperfecta (OI) is a genetic disorder which is characterised by bone deformity, low bone mass, connective tissue manifestations and brittle bones with history of multiple fractures. Although recurrent fractures are known in patient with OI, the occurrence of bilateral simultaneous fracture of humerus is quite rare. Presenting complaint and investigations: The patient had a fall in the outdoors during a storm during the height of covid pandemic and sustained injury to both arms. Radiographs revealed comminuted fracture of left distal humerus and transverse extraarticular supracondylar fracture of right humerus. Diagnoses, therapeutics interventions, and outcomes: Although, conservative measures were advised as per the guidelines for orthopaedic surgery during the covid pandemic for most of the fractures, the decision to operate was made considering the morbid obesity and hampered mobility due to bilateral above elbow plaster.The patient underwent staged open reduction and internal fixation of both distal humerus with anatomical locking plates in a span of 2 weeks. She recovered uneventfully with a good functional range of movements and resumed her routine activities. Conclusion: The treatment for complex and unusual fractures should be individualised and should take into consideration of patient’s general condition and safety.
Long Progression-free-survival Pancreatic Carcinosarcoma Under Gemcitabine-nabpaclitaxel First Line Chemotherapy
Carcinosarcoma of the pancreas is a rare entity with short case series reported in the literature. Diagnosis is established by immunohistochemical examination including both carcinomatous and sarcomatous components. Prognosis is usually limited to 6-9 months life expectancy. Standard chemotherapy regimen is not well defined. We present a case of pancreatic carcinosarcoma with long-time progression-free-survival under first line chemotherapy treatment with gemcitabine-nabpaclitaxel combination. Tumor histopathological and clinical characteristics are reviewed.
71-year-old male patient with hypertension, obesity and personal history of prostate adenocarcinoma with blast bone metastases. Admitted after fall and pathological right pertrochanteric fracture. Programmed surgery is performed by means of endomedullary nailing on the fractured right hip and prophylactic left hip. Pre-surgical nasopharyngeal exudate for coronavirus is positive, with no apparent clinical translation. Three hours after surgery, the patient begins with dyspnea, central thoracic pain of a pleuritic nature and a feeling of imminent death. Physical examination reveals poor general condition, hypotension, diaphoresis, tachypnea and desaturation, without neurological affectation. Treatment is initiated with intensive serotherapy, oxygen therapy and analgesia. Analysis reveals troponin and normal NT-proBNP with elevated LDH and D-dimer, as well as mild metabolic acidosis. The electrocardiogram and transthoracic echocardiogram do not show any alterations. Urgent pulmonary CT-angiography targets signs compatible with fat embolism (see figure 1). The hemodynamic and respiratory instability improve progressively, not requiring admission to ICU, appearing at twelve hours bilateral axillary petechiae. Pulmonary fat embolism syndrome is rare, and can appear after fractures and long-bone surgery . The classic clinical triad is hypoxemia, neurological alteration and petechiae[²], due to the presence of fatty emboli in the circulation and pulmonary parenchyma.
A world in the head: Brain abscess caused by Paradoxical embolism due to pulmonary arteriovenous fistula as a debut of hereditary hemorrhagic telangiectasia
66-year-old patient with a history of alcoholism and smoking, chronic iron deficiency anemia treated with oral iron who was admitted for streptococcal brain abscess, during the etiological study we found arteriovenous shunt on echocardiography and pulmonary arteriovenous fistula, undergoing endovascular closure of the same during stay. In the physical examination, perioral teleangiectasis was observed, when meeting the Curaçao criteria, a genetic study of hereditary hemorrhagic teleangiectasia was requested, which was positive.
Male Sexual Assault – A Case Report of Foreign Body in the Rectum from Sexual Assault by Female Partner
Most rectal foreign bodies (FB) are a result of insertion for sexual gratification. FB in the rectum as. result of sexual assault in males by the female partner is rare. A 32-year-ol man presented with a 6-day history of deep anal pain and lower abdominal pain, following an assault by a female partner while he was drunk. Physical examination and plain radiography confirmed a FB in the rectum. The FB was removed at exploratory laparotomy following failed attempt at trans rectal removal under spinal anaesthesia. The FB was confirmed to be a perfume canister. The patient has remained well at two months of follow up. Male sexual assault by female is not uncommon and can lead to disastrous effects. The female sexual assault on male is underreported and reported usually when there are complications. There is need to do more in-depth study to investigate the incidence of this.
Rubinstein-Taybi syndrome (RSTS) is a congenital syndrome most associated with mutations on chromosome 16p13.3 that can result in both benign and malignant neurologic and hematologic neoplasms of various primary origins. We present the case of a 39-year old female with RSTS who presented with severe abdominal and pelvic pain. Abdominal and pelvic imaging revealed multiple masses involving the uterus, liver and spleen concerning for malignancy. Biopsies from the endometrium and cervix confirmed this as a poorly differentiated, widely invasive squamous cell carcinoma. This represents the first case of primary squamous cell carcinoma of gynecologic origin in a patient with Rubinstein-Taybi syndrome. This case aims to raise awareness of the gynecological malignancy in patients with RSTS as well as serves as a reminder to clinicians to have a broad differential diagnosis in all patients which may help lead to early recognition of pathology.
This paper presents results of the author on Salvia officinalis and Salvia microphylla and COVID19. The results were achieved with dried Salvia officinalis leaves and with fresh Salvia microphylla leaves. The properties of fresh leaves appear with the taste as being much richer in antiviral agents, drying reduces the antiviral activity. The experiments presented in this paper are on the author himself, do not involve biosampling to confirm in laboratory but existing data in the published literature confirms the excellent efficiency of Salvia officinalis against COVID19 and a large array of other diseases. The self-experiments were very successful against COVID19, opening a path for natural treatment.
Epithelial-myoepithelial carcinoma of floor of mouth: A case report of double clear cell variant with immunohistochemical correlation
Epithelial-myoepithelial carcinoma (EMC) is a rare biphasic low-grade malignancy accounting for only 0.5% of all salivary gland tumors. Commonly, EMC affects parotid gland (70%) and rarely affecting other salivary glands. Clearing of both, epithelial and myoepithelial cell types, is rare and gives an impression of a monocellular neoplasm. Case report: A 42-year-old male reported to Oral and Maxillofacial Surgery Department in Faculty of Oral and Dental Medicine, Misr International University with a painless growth in the floor of mouth since 5 years. The soft tissue window of computerized tomography (CT) revealed a well-circumscribed swelling in the sublingual space. The provisional diagnosis was pleomorphic adenoma. Results: The histopathological examination showed solid sheets of rounded to polyhedral clear cells forming lobes and lobules separated by connective tissue mucoid septa. A thin fibrous capsule, invaded with some tumor cells was also present. The presented pattern of clear cells together with the encapsulation of the tumor provides an impression of clear cell variant of monocellular neoplasm. Conclusion: The presented case relates to an epithelial-myoepithelial carcinoma originating from the sublingual salivary gland, which is a rare site for this lesion. Based on immunohistochemical staining, differentiation between the double clear cell types was confirmed using S-100 protein and SMA for the myoepithelial nature of the outer cells while the epithelial nature of the inner cells was confirmed by CK-19 and EMA. Thus, the diagnosis of double clear cell variant of EMC was given.
Background Estrogen receptors (ER), Progesterone receptors (PR) expression is seen in non cancer breast lesions like juvenile fibroadenomas and phyllodes tumour. Materials and Methods This is a prospective study on a study population that comprised fibroadenomas and phyllodes tumor. Results While a few studies indicate that ER/PR expression correlates with a more benign outcome ,we did not see the same in our population. Ki 67 proliferation was greater in the stromal component of phyllodes tumours,compared to fibroadenomas.
