Project description:Testicular epidermoid cysts are a rare cause of testicular pathology. No cases of recurrence or metastasis have been reported in the literature. As a result, inguinal partial orchiectomy with frozen section has recently become standard treatment. A 43-year-old male presented with right testicular discomfort and the presence of mass. Right inguinal partial orchiectomy with frozen section was performed, and the right testicle was preserved. The final pathology report confirmed the diagnosis of an epidermoid cyst. The importance of accurate diagnosis of this benign lesion is crucial for the prevention of unnecessary radical orchiectomy.

Project description:A retrorectal epidermoid cyst is an uncommon congenital lesion that arises from the remnants of the embryonic tissues. This type of cyst is difficult to diagnose before surgery. In this study, we report a rare case of a giant retrorectal epidermoid cyst in a 30-year-old woman. Initially, the condition was diagnosed as a perianal abscess and treated with incision and drainage. Since the abscess recurred, a pelvic magnetic resonance imaging was ordered, which revealed an 8.2?cm perianal cyst with appearance not compatible with an abscess. Postsurgical histologic analysis confirmed a retrorectal epidermoid cyst. Postoperative course was uneventful, and the woman was discharged on postoperative day 3. She was doing well at 4 months of follow-up. This report suggests that retrorectal cysts should be considered in cases of recurrent perianal swellings/abscesses.

Project description:A glandular odontogenic cyst (GOC) is a developmental cyst that is a clinically rare and histopathologically unusual type of odontogenic cyst. GOCs are now relatively well-known entities; their importance relates to the fact that they exhibit a propensity for recurrence rates from 21% to 55%, similar to odontogenic keratocysts, and may be confused microscopically with central mucoepidermoid carcinoma. Furthermore, some microscopic features of GOCs may also be found in dentigerous, botryoid, radicular and surgical ciliated cysts. The present case report aims to describe a typical case of GOC, throwing light on its epidemiology and origin, as well as on its clinical, radiographic and microscopic features, which may be helpful for diagnosis in problematic cases, long-term follow-up and to determine the most appropriate treatment.

Project description:Epidermoid cyst in the penis is uncommon and only a small number of cases have been reported. We presented a thirty-two-year-old male patient with a case of slow growing, mobilized, non-tender frenulum of the penis mass that developed in 10 years period. Surgery treatment was taken under local anesthesia. Pathological examination was revealed as epidermoid cyst. Care must be given during examination of these lesions to rule out another entity. If there is any indication, complete excision is the best treatment as another treatment may lead to the risk of recurrence.

Project description:BackgroundThe epidermoid cyst as a pineal region tumor is an infrequent pathology and with few descriptions in literature. Its prevalence in the third ventricle is 0,0042% of all intracranial tumors. To achieve a complete exéresis we used an endoscopic supracerebellar-infratentorial approach, surgical technique for pineal region approach.ObjectivesThe purpose of this work is to show the surgical technique of this novel approach for the treatment of a very infrequent disease.Methods16 years old male patient with history of diabetes insipidus and chronic headaches (m-RS 1). Brain MRI showed a lesion with hyperintensity in T2WI and hypointensity in T1WI. It presents peripheral enhancement with gadolinium and restricted diffusion pattern in DWI. The pituitary stalk also showed enhancement with contrast. Germ cell tumor was a possible diagnosis but tumor cell markers were negative in CSF samples. We decided to make the purely endoscopic approach to the region to make a biopsy and a possible resection. Intraoperative pathology result informed an epidermoid tumor, so we continued with the complete exeresis of the tumor.ResultsWe achieved a complete resection of a third ventricle epidermoid cyst with a purely endoscopic supracerebellar-infratentorial approach and a skull base rigid endoscope in a 16 years old male patient. The patient has recovered without any sequelae, headaches free but persistence of diabetes insipidus (m-RS 1).Conclusion: The purely endoscopic supracerebellar-infratentorial approach is a safe option to the surgical management of third ventricle pathologies, in this case, an epydermoid cyst.

Project description:Epidermoid cysts are rare benign tumors developed by ectodermic inclusions. They are usually located at the level of the pontocerebellar angle, the parasellar region and the temporal fossa. They exceptionally develop at the level of the fourth ventricle We report the case of a 47-year old woman admitted for intracranial hypertension syndrome associated with walking disorders. The diagnosis of fourth ventricle epidermoid cyst was evoked based on diffusion MRI data then confirmed intraoperatively and by histologic examination. Subtotal surgical excision was performed due to capsule adhesion to the upper part of the V4 floor. After a 36-month follow-up, the patient showed no signs of tumor recurrence.

Project description:INTRODUCTION: Epidermoid cysts are known as embryonic or acquired ectopic aberrations of the ectoderm. To the best of our knowledge, there are only a few reports of elderly onset intramedullary epidermoid cysts. We report a case of elderly onset intramedullary epidermoid cyst at the conus medullaris. CASE PRESENTATION: A 63-year-old Japanese woman working as a farmer presented with slowly progressive gait disturbance and voiding dysfunction. A magnetic resonance imaging scan revealed an intramedullary mass lesion at L1 to L3. We diagnosed the lesion as an intramedullary spinal cord tumor. A laminectomy was performed at the level of Th12 to L3. Upon spinal cord dissection, a yellowish milky exudation erupted from the cystic lesion. We resected white cartilage-like pieces from the cystic cavity. Because the wall of the cystic lesion tightly adhered to the spinal cord parenchyma, we abandoned complete resection of the cyst wall. The pathological diagnosis was an epidermoid cyst. CONCLUSIONS: We propose that evacuation of the cyst contents is preferable, especially in cases with elderly onset and congenital origin.

Project description:Introduction and importanceThe falciform ligament is a peritoneal fold that extends from the anterior abdominal wall to the liver, which divides the liver into two lobes. Cysts of the falciform ligament are rare and without an apparent cause. The range of the symptoms can vary from abdominal pain to asymptomatic patients. Cysts are treated surgically, and resection is used to make a definitive diagnosis.Case presentationA 36-year-old female patient was treated at an outpatient facility for epigastric pain that lasted for three months. Abdominal MRI and MSCT were performed to verify a cyst formation in the left liver area of about 12 cm in size. Laparoscopic resection of the cist was performed under general endotracheal anaesthesia.Clinical discussionFalciform ligament tumours can be malignant or benign. Treatment of the cyst includes complete excision and pathohistological diagnosis to rule out malignancy. In most cases reported thus far, excision has been done after laparotomy. In our case, the operation was performed in a less invasive way, laparoscopically.ConclusionLaparoscopy can serve as a diagnostic and therapeutic method for cysts of the falciform ligament, both smaller and more significant, that infiltrate the surrounding structures.
