Project description:Chondroblastoma is a benign bone tumor, represents 1%-2% of all primary bone tumors, typically seen in patients 10-25-year-old and more common in males. It occurs most frequently in the distal femur, proximal tibia, and proximal humerus. Soft tissue extension is extremely rare. Adjacent joints may develop effusions, but the tumor mass protruding into the joint has never been seen in case of chondroblastoma. We report a rare case of intra-articular chondroblastoma arising from proximal tibia in a 16-year-old boy and growing into the knee joint mimicking an intra-articular osteochondroma.

Project description:AbstractDermoid cyst is a congenital and benign disease with most occur on the head and neck. It is rarely that occur on the nasal tip and nasal septum at same time and rarely repair of using nasal septum mucosa. The authors treated a child with dermoid cyst in the nasal tip and septum. Only the dermoid cyst at the tip of the nose caused the change of appearance. Dermoid cyst of nasal septum did not cause any clinical symptoms. She underwent excision of the dermoid cyst at the tip of the nose and endoscopic surgery for the dermoid cyst in the nasal septum and used the nasal septum mucosa for repair at the same time. After 6 months of recovery, the appearance of the nasal tip recovered well without obvious scar, the nasal septum area recovered well, and the local stoma was unobstructed without recurrence. The authors found that this kind of nasal septal cyst with no clinical symptoms can achieve good therapeutic effect through endoscopic surgery and repair of using nasal septum mucosa, with less damage, rapid recovery, and good prognosis.

Project description:AimTo study clinical features and gene mutations within the paired-like homeodomain transcription factor 2 (PITX2) gene in a pedigree of bilateral limbal dermoids.MethodsComplete eye examinations have been performed on each individual of the family. Exons of paired-like homeodomain transcription factor 2 (PITX2) were amplified by polymerase chain reaction, sequenced, and compared with a reference database.ResultsWe described the phenotype, clinic findings in a family with two affected members. The masses of the proband's eyes were excised surgically demonstrating a dermoid cyst by histopathological examination. No mutation was detected in the gene PITX2 in this pedigree.ConclusionA family of limbal dermoid cyst was reported. In addition, no pathogenic sequence variations were found in PITX2, indicating that this phenotype in this family is a distinctive entity.

Project description:Dermoid cysts are benign and congenital ectodermal inclusions. Their occurrence in an intracranial location is quite rare. They constitute 0.1 to 0.7% of all intracranial tumors. Their occurrence in the fourth ventricle and their multicentric feature are extraordinary. A 12-year-old boy was admitted to our clinic with a dermoid cyst with sixth cranial nerve involvement. He had symptoms of increased intracranial pressure. This case is the first dermoid cyst in the literature at this unusual location; a mature tooth structure was found within the cyst, which extended over the cervical subsegments. There was a second dermoid cyst in the thoracic spine (multicentric). Our aim is to present an atypical dermoid cyst along with radiodiagnostic characteristics and macroscopic findings.

Project description:IntroductionA pyosalpinx is the acute inflammation of the Fallopian tube fills up and swells with pus, which commonly results from inadequate or delayed treatment of pelvic inflammatory disease. Herein we report a case of bilateral pyosalpinx mimicking an ovarian torsion.Presentation of caseWe reported the case of a 27-year-old female patient, who presented to the emergency department with complaints of constant, worsening lower abdominal pain for 2-3 days. Pelvic and transvaginal ultrasound examinations were performed which demonstrated a large, complex cystic structure in the right adnexa with peripheral flow on color Doppler imaging. The possibilities included ovarian torsion or hemorrhagic cyst. Intraoperative findings showed bilateral pyosalpinx and treated successfully by laparoscopic bilateral salpingostomy.ConclusionThe present case highlights the diagnostic dilemma of bilateral pyosalpinx must be taken into account in the differential diagnosis of ovarian torsion or tumor, particularly in women of reproductive age.

Project description:BackgroundOsteoid osteoma is a painful benign skeletal tumour of unknown aetiology. Most often it occurs in the long bones of extremities and responds well to nonsteroidal anti-inflammatory medications. However, unusual localization and atypical presentation of this tumour might present a diagnostic challenge, especially if symptoms mimic that indicative of juvenile spondyloarthritis.Case presentationA misdiagnosed ten-and-a-half-year-old girl with osteoid osteoma involving the distal phalanx of a little finger is presented. Her initial symptoms were pain and swelling of the little finger resembling dactylitis, while various imaging modalities showed signs of tenosynovitis, indicating a possible development of juvenile spondyloarthritis. Several trials of different non-steroid anti-inflammatory drugs gave no satisfactory results and ultrasound guided triamcinolone-hexacetonide injection provided only a short relief. Finally, almost three years after initial presentation, persistent clinical symptoms warranted repeated imaging that raised suspicion of an osteoid osteoma. Directed treatment with surgical intervention led to almost immediate and complete resolution of her symptoms.ConclusionsOsteoid osteoma should be suspected in case of a tender swelling of a digit in children and adolescents, regardless of initial imaging findings and clinical presentation. Early diagnosis and treatment of this benign condition can have a substantial impact on quality of life of patients and their families and protect them from many unnecessary diagnostic procedures and treatment.

Project description:Primary lung adenocarcinoma, diffuse pneumonic type, can mimic the clinical presentation of an infectious or inflammatory lung disease, which can represent a diagnostic challenge. We present an unusual case of adenocarcinoma of the lung refractory to treatment, associated with rapid deterioration of respiratory status, ARDS requiring intubation and ultimately death.

Project description:Intracranial dermoid cysts are benign lesions that may be diagnosed incidentally or present symptomatically due to mass effect-focal neurological deficits, seizures and/or hydrocephalus-or chemical meningitis secondary to spontaneous rupture. The use of tubular retractors in minimally invasive parafascicular surgery (tsMIPS) has been described extensively as a technique to preserve neurological function whilst safely maximizing the extent of resection. The authors present the first use of the tsMIPS approach for removal of a dermoid cyst in a 68-year-old female who presented with abulia and seizures due to a large Sylvian fissure dermoid cyst. This approach minimized trauma to surrounding cortical-subcortical structures, as supported by connectome analyses, without sacrificing visualization of the operative field. Additionally, itavoided manipulation of the lenticulostriate arteries attached to the walls of the dermoid cyst. The use of an endoscope ensured complete drainage of the cyst components and therefore the effectiveness of the procedure.

Project description:We report the case of a 39-year-old woman who presented in an acute setting with pelvic pain, an adnexal mass on imaging and a high CA19-9 level. She was taken for surgery, where a large dermoid cyst was found at the fimbrial end of a fallopian tube at the time of laparoscopy, with no apparent connection to either ovary and absence of ovarian necrosis. This was corroborated on final histology. Dermoid cysts in aberrant locations are usually reported at Caesarean section or during laparoscopic sterilisation and thus, understandably, a pre-operative CA19-9 level is rarely available. That and the rarity of these 'ectopic dermoids' make it hard to give further support for a causative association with the high tumour marker levels. Some authors suggest that auto-amputation of a dermoid cyst or part thereof and subsequent reimplantation may give rise to this phenomenon, and thus the term 'wandering dermoid' has been applied to similar situations. This is what we postulated as the cause in our case. It is likely that a full understanding of the aetiology of wandering dermoid cysts will remain elusive, given the paucity of cases.
