Giant cell tumor of the tendon sheath in a 5-year-old child; A case report.

ABSTRACT:

Introduction

and importance: Giant cell tumors of the tendon sheath in children have rarely been reported in the literature. This study aims to present a case of giant cell tumors of the tendon sheath on the big toe of a 5-year-old child.

Case presentation

A 5-year-old girl presented with a painless swelling over the dorsal aspect of right big toe for 2 weeks. Physical examination revealed non-tender rubbery like swelling over the dorsal aspect of the right big toe. Ultrasound scan of the swelling showed a 17 × 7 mm oval-shaped subcutaneous hypoechoic lesion. Magnetic resonance imaging showed evidence of 20× 8 mm well-defined fusiform soft tissue lesion scalloping the bone. Under general anesthesia, the mass was totally excised. Microscopic sectioning showed a mixture of fibroblasts and histiocyte like cells associated with multinucleated giant cells in the vascular connective tissue stroma with the definite diagnosis of the giant cell tumor of the tendon sheath.

Discussion

These tumors mostly compose of several types of cell like synovial, siderophages, foam, inflammatory and multinucleate giant cells. The major etiological factors that induce development of this tumor could be traumatic, inflammatory, metabolic or neoplastic disease.

Conclusion

although it is a sporadic finding, giant cell tumors of the tendon sheath might affect the lower limb in children. Complete excision is the main modality of treatment.

Case Report: Giant Cell Tumor of Tendon Sheath After Breast Augmentation.

Project description:Giant cell tumor of tendon sheath (GCTTS) is a benign tumor. It occurs predominantly in the hands, ankles, and knees. A 39-year-old female presented with GCTTS in the right breast after breast augmentation. There was a clear borderline between the tumor and breast tissue. In terms of morphological appearance, synovial metaplasia could be observed in part of the collagenous capsule. The tumor was moderately cellular and was composed of synovium-like monocytes. The main part of the tumor was blended with nested and scattered xanthomatous cells, lymphocytes, and osteoclast-like giant cells. Hemosiderin granules were distributed in the lesion. Immunohistochemical staining and fluorescence in situ hybridization (FISH) analyses were performed. CD68 staining was positive in osteoclast-like giant cells. In addition, neither significant USP6 translocation nor CSF1 translocation was detected by FISH. We hypothesized that the pathogenesis of this rare GCT-TS was based on synovial metaplasia and did not depend on the translocation of classical CSF1.

Posterior shoulder dislocation in a 10-year-old child: Case report.

Project description:IntroductionShoulder dislocation is the most common type of all joints dislocations. It occurs when there is separation in the glenohumeral joint. Posterior dislocation accounts for less than 4% of all shoulder dislocations. In fact, it is misdiagnosed in 60-79% of the patients in the initial presentation. In children a posterior shoulder dislocation is usually caused by a congenital anomaly or in those who have ligamentous laxity. Traumatic posterior shoulder dislocation without fracture of the proximal humeral epiphysis in children is very rare, and only few cases have been reported.Case presentationThis report presents a rare case of a 10-year-old child with a traumatic posterior shoulder dislocation without fracture.Discussionthis patient present with a rare posterior dislocation, which is direct and without fracture. It does not present with a marked deformity and it is hard to detect without a complete physical examination and radiographic series.ConclusionPosterior shoulder dislocations are rare, and even more rare in children without fractures. It is easily missed and needs careful history taking, physical exam and correct x-ray view to reach the diagnosis.

Giant Cell Tumor of Tendon Sheath and Tendinopathy as Early Features of Early Onset Sarcoidosis.

Project description:Giant cell tumor of tendon sheath (GCTTS) is characterized by diffuse proliferation of synovial-like cells and multinucleated giant cells along tendon sheaths. This benign tumor typically presents in the third to fourth decade of life and is exceeding rare in children. Here we describe a case of a 10-years-old girl with a history of soft tissue swelling involving the third digit of left hand, bilateral wrists and ankles. Pathology of the finger mass revealed abundant multinucleated giant cells consistent with GCTTS. Resection of the tendinous masses from the ankles also showed multinucleated giant cells along with chronic bursitis. She began to show features of polyarticular arthritis by age 7. Due to progression of arthritis, whole exome sequencing was performed and found a de novo heterozygous mutation in NOD2 (p. R334Q). This variant is the most common mutation responsible for early onset sarcoidosis (EOS)/Blau syndrome, an autoinflammatory disease characterized by granulomatous inflammation of joints, skin and eyes. The early onset of symptoms and presence of multinucleated giant cells and granuloma in this case are in keeping with a diagnosis of EOS/Blau syndrome. The patient responded well to treatment with methotrexate and etanercept. This case extends the clinical spectrum of EOS/Blau syndrome, which should be considered for GCTTS and other unusual presentations of tendon inflammation in children, even in the absence of the characteristic triad of arthritis, dermatitis and uveitis.

Gastroblastoma in a 5-year-old child: a case report and literature review.

Project description:BackgroundGastroblastoma is an extremely rare stomach tumor with a biphasic cell morphology of epithelioid and spindle cells. Due to the low incidence rate and the lack of specific clinical characteristics, it is easy to misdiagnose. Detailed imaging analysis is also unavailable. At present, we reported a case of gastroblastoma to analyze its clinical and imaging characteristics. In addition, we reviewed the imaging findings, current diagnosis, treatment, and outcome of gastroblastoma.Case presentationA 5-year-old girl was admitted to our hospital with upper abdominal pain and melena. Endoscopic examination showed a protuberant submucosal mass on the greater curvature of the gastric body. Abdominal ultrasonography and an abdominal enhanced computed tomography further confirmed the mass. The patient was pathologically diagnosed with gastroblastoma after radical surgery in February 2021.ConclusionWe described a rare case of gastroblastoma and may provide a new perspective on imaging diagnosis, treatment, and outcome of this tumor. Gastroblastoma tends to occur in male patients, typically affects young people, and has low malignant potential and a low rate of recurrence and metastasis. Gastroblastoma usually arises in the gastric muscularis propria with hypoecogenic and submucosal characteristics in ultrasound examination and significant enhancement in computed tomography (CT) scan. Surgical resection and regular follow-up after surgery are the main management of the disease. Clinicians should strengthen the understanding of this rare tumor for early detection and treatment.

Malignant Transformation of Grade II Ependymoma in a 2-Year-Old Child: Case Report.

Project description:Ependymomas are central nervous system neoplasms that account for a third of all posterior fossa tumors in children. The most common location for infratentorial ependymoma is within the fourth ventricle. We present a case report of malignant transformation of an infratentorial grade II ependymoma in a 2-year-old child who presented with vomiting and visual disturbance. An infratentorial brain tumor in the left cerebellar area was totally removed, and the initial pathologic diagnosis was grade II ependymoma. The tumor recurred aggressively 1 year later; subtotal removal and adjuvant chemotherapy were performed. After a second operation, a histopathologic study was performed. The second specimen was defined as a grade III anaplastic ependymoma. Transformation to grade III anaplastic ependymoma is possible for a grade II ependymoma but very rare. The diagnosis of the anaplastic variant of intracranial ependymomas is difficult. Surgical treatment remains the mainstay of the treatment for all cases. Ependymomas in young infants have a worse prognosis than older children, so we need individual clinical evaluation and close follow-up of such cases. This article highlights the requirement of a close follow-up for grade II ependymomas for anaplastic transformation.

Pediatric Upper Cervical Spine Giant Cell Tumor: Case Report.

Project description:Study Design Case report. Objective The purpose of this work is to report the case of a giant cell tumor involving the second cervical vertebra in a pediatric patient. Surgical management included a combined posterior and anterior cervical approach. There has been no recurrence in 2 years of follow-up. Case Report A 13-year-old girl presented with scoliosis with incidentally lytic lesion involving the second cervical vertebra. The radiologic investigations and biopsy result indicated a giant cell tumor of the bone. A combined posterior and anterior cervical approach was performed to resect the lesion, reconstruct the spine, and restore stability. Two years of follow-up revealed no recurrence of the lesion with stable reconstruction of the spine. Results The lesion was surgically managed for excision and spinal fusion by combining a posterior occipitocervical arthrodesis with an anterior retropharyngeal cervical approach. The final histopathology result confirmed a giant cell tumor of the bone. Conclusions Giant cell tumor involving the second cervical vertebra is uncommon; this tumor can be managed surgically by using a combined posterior and anterior cervical retropharyngeal approach. The presented case was unique in terms of the tumor location, patient age, and surgical management.

Pseudomonas oryzihabitans sepsis in a 1-year-old child with multiple skin rashes: a case report.

Project description:BackgroundPseudomonas oryzihabitans is a Pseudomonas bacterial organism rarely implicated in human infections. The bacterium has been isolated in a few reported cases of neurosurgical infections and patients with end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections. Limited information exists in developing countries, however, because of the lack of advanced microbiological tools for identification and characterization of this bacterium. This case report describes the isolation of a rare Pseudomonas bacterium in a patient presenting with sepsis and skin infection.Case presentationA 1-year-old girl was presented to a hospital in the northeastern part of Ghana with a 1-week history of pustular rashes on her scalp and neck, which occasionally ruptured, along with discharge of yellowish purulent fluid. The child is of Mole-Dagbon ethnicity and hails from the northern part of Ghana. Pseudomonas oryzihabitans was identified in the patient's blood culture using the 16S ribosomal deoxyribonucleic acid sequencing technique. The rash on the patient's scalp and skin resolved after continuous treatment with gentamicin while her condition improved clinically.ConclusionsThis finding suggests the potential of this bacterium to cause disease in unsuspected situations and emphasizes the need to have evidence for the use of the appropriate antibiotic in clinical settings, particularly in rural settings in Africa. It also brings to the fore the unreliability of conventional methods for identification of Pseudomonas bacteria in clinical samples and thus supports the use of 16S ribosomal deoxyribonucleic acid in making the diagnosis.

Idiopathic unilateral third nerve palsy with pupillary sparring in 10-year-old child -a case report.

Project description:Introduction and importanceAneurysm, diabetes mellitus, central nervous system (CNS) infections, pituitary tumors, and ischemia alterations are all potential causes of unilateral oculomotor nerve palsy, a common clinical disease.Case presentationA 10-year-old child presented with right eyelid ptosis and restricted eye movements associated with diplopia and pain in the right eye. Brain imaging and laboratory tests revealed no obstruction, infection, or hypercoagulable state. The condition was labeled as idiopathic. A patient was diagnosed with ptosis through a sling procedure and after 2 and 4 weeks of follow-up was told he had mild anemia. The patient was prescribed ferrous sulfate 8mg once daily for 4 months and his condition improved.Clinical discussionSurgery can correct the appearance of crossed eyes, but it seldom restores or significantly improves binocular function. Amblyopia and the loss of binocular vision can occur in children with third nerve palsy due to the excessive angle of incitant strabismus and the resulting ptosis.ConclusionPatients with idiopathic third nerve palsy must be informed of their prognosis so that they can make an informed decision about whether or not to undergo surgery. Clinical examination is the only way to identify a child's condition and proper investigations and a full history of prenatal and antenatal courses are required.
