Dermoid cysts are rare benign tumors that arise from ectopic epiblastic inclusions and account for 0.4% to 1.5% of all tumors. They are usually 1 to 5 cm in size and composed of a pasty semisolid material. The orbital dermoid cyst is the most common type. Dermoid cysts can also occur in the spinal cord, ovaries, and pancreas. We encountered a 24-year-old man with a dermoid cyst over the left sternoclavicular joint. He reported intermittent secretion of a white tofu-like exudate from an underlying congenital sinus tract since birth. The secretion had turned hemorrhagic for the last month and had been accompanied by progressive swelling and pruritus for 1 week. Ultrasonography and magnetic resonance imaging revealed characteristics of a dermoid cyst, and histopathological examination confirmed the diagnosis. The patient underwent surgical excision of the cyst under local anesthesia. The incision healed well with no postoperative complications. Considering that a dermoid cyst has the potential to become infected or progress into squamous cell carcinoma, its removal at an early stage is suggested. Few reports in the literature have described a dermoid cyst that secretes hemorrhagic contents from a congenital sinus tract. We present this case to provide a reference for clinicians.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Introduction: Lipomas are benign soft tissue tumors, characterized by the presence of mature adipocytes in histopathology. Their development is slow and their etiologies are still controversial. Frequently subcutaneous, this type of lesion is rarely present in the oral cavity. Observation: A 67-year-old man consulted for a nodule on the inner face of his right cheek which had been developing for several years, with severe discomfort during chewing. The typical clinical aspect of this lesion suggested a lipoma. Magnetic resonance imaging (MRI) was performed before surgical excision in order to establish a differential diagnosis with a well-differentiated liposarcoma. Comments: The various imaging examinations, particularly MRI, combined with the analysis of the fat component and the morphology of the non-fat component (septa) enable us to define several categories of lesions likely to have a benign or malignant character. However, some lesions remain difficult to classify, and it is the histopathological examination along with, if necessary, immunohistochemistry (anti-MDM2 and/or anti-CDK4), which allows to confirm or not the malignancy of a lesion. Histological examination suggested a fibrolipoma. Conclusion: Although benign, the size of a fibrolipoma may can lead to significant functional and aesthetic discomfort for the patient. Surgical excision remains the treatment of choice.

Abstract Background Osteochondromas are a benign outgrowth of bone and cartilage and one of the most common bone tumors that usually occur in long bones, with only 1–4% being located in the spine, more frequently in the cervical and upper dorsal region, and rarely the lumbar spine. Here, we report a case of lumbar spine (L5) osteochondroma arising from the neural arch. Case presentation A 30-year-old man presenting with a solid painless mass at the lower lumbar region. No neurological symptoms. Radiological examinations revealed an exophytic lesion in the fifth lumbar articular process, and the spinous process appears to be a solitary osteochondroma. Lumbar spine magnetic resonance imaging showed a bony lesion covered by a 2-mm-thick cartilaginous cap. Surgical en bloc resection of the mass was performed, and the histopathological examination confirmed the diagnosis of osteochondroma. No evidence of recurrence at the end of 4-year follow-up. Conclusion Osteochondromas are benign tumors rarely present in the spine; diagnosis can be made by the typical appearance of the cartilaginous cap over the mass in the magnetic resonance imaging. Surgical excision is the best management option.

Place and Duration of Study: Departments of Radiology, Orthopedics and Pathology of Pakistan Institute ofMedical Sciences, Islamabad, from Jan 2018 to Jan 2019. Methodology: All the patients who had complain of bone deformity or pain with high suspicion of neoplasticpathology involving bone and soft tissue on radiograph were included in study. Patients were first diagnosed on conventional radiography followed by magnetic resonance imaging. Magnetic resonance imaging with contrast was done on Phillips 1.5 tesla machine. T1W, T2W, STIR images, Fat suppressed, PD spair and post contrast T1W images were obtained. Positive magnetic resonance imaging findings which were noted were; marrow involvement, cortical break, soft tissue involvement, joint involvement, neurovascular bundle involvement and post contrast enhancement on T1W imaging. Then bone biopsy was performed. The removed bone was sent for histopathological examination in all cases. The histopathological reports were collected. The results were entered in structured proformas. Data was collected after the informed consent. All the data was entered and analyzed using SPSS version-23. Results: Fifty patients of both genders were recruited during our study duration. 32 (64.0%) were male while 18(36.0%) were female patients. Mean age of the patient was 54.5 ± 14.3 years with range 18 to 80 years. Among the benign tumors vertebral hemangiomas were most commonly found 5 (10.0%) followed by osteochondroma which was 4 (8.0%), while among malignant........

Dermal Sinus Tract

Abstract Prevotella species are gram-negative anaerobic commensal bacteria of the oropharynx, which frequently cause periodontal disease but are otherwise rarely implicated in serious bacterial infections. Cranial dermoid cysts are benign neoplasms that grow along the planes of the embryonic neural tube closure. In infants, they most commonly present in frontal locations, including periorbital, nasal, and within the anterior fontanelle. Although dermoid cysts are slow growing, usually uncomplicated, and easily treated definitively with surgical excision, cranial cysts located on the midline are associated with a higher risk for persistent dermal sinus tract with intracranial extension of the tumor. We describe a case of a 10-month-old male patient with an occipital midline dermoid cyst with intracranial extension, infected with Prevotella melaninogenica, and complicated by intracranial abscess formation and meningitis.This case highlights two unusual disease entities: the uncommon occipital location of a dermoid cyst, and complications of that cyst caused by a serious bacterial infection with a normal oral flora. We discuss the recommendation for neuroimaging prior to surgical excision of a midline dermoid cyst, given the risk for dermal sinus tract with intracranial communication. We also discuss potential mechanisms for bacterial inoculation of this cyst with Prevotella melaninogenica. This pathogen has not previously been reported as a complication of dermoid cysts.

Primary intracerebral manifestation of multiple myeloma is rare and usually arises from the meninges or brain parenchyma. The authors present a case of multiple myeloma primarily manifesting within the lateral ventricle. A 67-year-old man was admitted with headache accompanied by slowly progressing right hemiparesis. Magnetic resonance imaging showed a large homogeneous contrast-enhancing intraventricular midline mass and hydrocephalus. The tumor was completely resected, and histopathological examination revealed plasmacytoma. After postoperative radio- and chemotherapy, vertebral osteolysis was detected as a secondary manifestation of multiple myeloma.

AbstractObjective:To assess the efficacy of excision of nasal dermoids through a closed rhinoplasty incision. This is the first description of the use of this approach for excision of superficial nasal dermoids.Methods:Three boys aged five, nine and 12 years presented with midline nasal dermoids with minimal cutaneous involvement. Magnetic resonance imaging demonstrated distinct, cystic, superficial nasal masses. The cysts were excised through a closed rhinoplasty approach. In each case, completeness of extirpation was judged by histopathological examination of the excised specimen. Aesthetic outcome was recorded photographically.Results:All three patients' cysts were completely excised, with excellent cosmetic results.Conclusions:The closed rhinoplasty incision is another approach in the surgeon's armamentarium for excision of small, superficial nasal dermoid cysts. In well selected cases, this approach gives optimal cosmetic results, provides adequate exposure with minimal dissection, and allows total extirpation.

Early Response Assessment

Chordoma in pediatric patients is very rare. Proton therapy has become a gold standard in the treatment of these neoplasms, as high dose escalation can be achieved regarding the target while maximizing the sparing of the healthy tissues near the tumor. The aim of the work was to assess the evolution of morphological sequences during treatment using T1/T2-weighted magnetic resonance imaging (MRI) for the early response assessment of a classic chordoma of the skull base in a pediatric patient who had undergone surgical excision. Our results demonstrated a significant quantitative reduction in the residual nodule component adhered to the medullary bulb junction, with an almost complete recovery of normal anatomy at the end of the irradiation treatment. This was mainly shown in the T2-weighted MRI. On the other hand, the classic component of the lesion was predominantly present and located around the tooth of the axis. The occipital condyles were morphologically and dimensionally stable for the entire irradiation period. In conclusion, the application of this type of monitoring methodology, which is unusual during the administration of a proton treatment for chordoma, highlighted the unexpected early response of the disease. At the same time, it allowed the continuous assessment of the reliability of the treatment plan.
