Project description:Adenoid cystic carcinoma of the Bartholin Gland (BG-ACC) is a rare form of vulval cancer with only approximately 350 reported cases since 1864. A review of available literature and case reports suggests an aggressive nature with protracted clinical symptoms and a tendency for local recurrence despite adequate surgical excision with or without adjuvant radiotherapy. Survival rates of 71% and 59% are reported at five and ten years. This case report endeavours to add to our body of knowledge regarding this rare disease and thus help broaden and improve our understanding of management and treatment success.

Project description:IntroductionPulmonary adenoid cystic carcinoma (PACC) is a rare, low-grade malignant salivary gland-type tumor characterized by a dormant onset and slow progression, often leading to misdiagnosis. Due to its rarity, limited cases have been reported in the literature. This report aimed to enhance clinicians' understanding of this infrequent disease.Case presentationWe present the case of a 41-year-old female patient diagnosed with PACC. Our report provides a comprehensive analysis of the patient's imaging, pathology, and treatment, with a particular focus on immunohistochemical results. Importantly, we emphasize the significance of considering foreign bodies and tumors in the bronchus when encountering asthma-like symptoms unresponsive to conventional treatments. Due to the uncertain etiology and pathophysiology of PACC, there are currently no established guidelines for chemotherapy and radiotherapy.ConclusionPACC predominantly manifests as bronchial lesions without significant clinical heterogeneity. Therefore, it is crucial to consider foreign bodies and tumors in the bronchus when dealing with asthma-like symptoms, especially in patients without chronic lung disease who do not respond to anti-infective, antispasmodic, and antiasthmatic treatments. Additionally, meticulous examination of lesions is essential for timely diagnosis and intervention, ultimately improving patient survival rates.

Project description:Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site.

Project description:IntroductionLacrimal gland adenoid cystic carcinoma (LGACC) is characterized by a high rate of recurrence, perineural invasion, and propensity for distant metastasis, resulting in poor prognosis. This case report aimed to highlight the diagnostic and therapeutic challenges of LGACC, underscore the importance of resectioning the tumor as completely as possible for the first time, adhere to postoperative adjuvant therapy, and provide detailed insights into its surgical and diagnostic management that may not be extensively covered in large case series and meta-analyses.Case presentationA 34-year-old man presented with progressive left eye proptosis for 4 months. Initial evaluation and imaging led to a high suspicion of LGACC, which was confirmed after an eye-sparing excision of the left orbital tumor. The patient declined to undergo postoperative radiotherapy, which was recommended after the surgery. Thus, despite surgical intervention, the patient experienced tumor recurrence 3 months post-surgery, leading to orbital exenteration. Pathological examination confirmed the presence of poorly differentiated LGACC.This time the patient underwent postoperative radiotherapy, as recommended. However, despite local control, the patient developed an intracranial metastasis within a year.ConclusionLGACC presents significant diagnostic and therapeutic challenges owing to its insidious onset, lack of specific symptoms, and high potential for recurrence and metastasis. Thus, this case emphasizes the need for early diagnosis, aggressive treatment, and adherence to postoperative adjuvant therapy to improve patient outcomes. Future research should focus on understanding the pathogenesis of LGACC and on developing standardized diagnostic and treatment protocols to enhance patient prognosis and survival.

Project description:Cystic meningiomas are very rare tumors of the central nervous system. We report the case of a 62-year-old female how presented headaches resistant to usual analgesics with behavior disorders. Cerebral CT scan showed a right frontal extra-axial tumor with firm and cystic component, brain MRI evoked the diagnosis, surgery removed the entire tumor and histological examination confirmed it. A cystic meningioma should not be omitted from the differential diagnosis of brain tumors with a cystic component and which clinical, radiological, histological and therapeutic features are discussed.

Project description:Adenoid cystic carcinoma (ACC) is a malignant neoplasm, frequently affecting the salivary glands, and rarely occurring in other locations. ACC is characterized by slow growth, perineural invasion, local and late recurrence after original treatment. However, renal metastasis of ACC is very rare. To our best knowledge, only 11 cases of ACC metastasis to the kidney have been reported in the English literature to date. Herein, we presented a rare case of a 70-year-old man with renal metastasis from ACC of the right lung after 3 years of primary presentation. Our patient underwent right radical nephrectomy and histologically confirmed as Metastatic Adenoid Cystic Carcinoma.

Project description:ObjectiveTo describe clinical characteristics, imaging findings, morbidity, and mortality in a single-center cohort of 12 pediatric cavernous sinus thrombosis cases and to review all cases available in recent English literature.MethodsClinical data and radiographic studies on 12 cases from our institution were analyzed retrospectively. A literature search and review was conducted, with additional cases pooled with the new cohort for an aggregate analysis.ResultsTwelve cases of cavernous sinus thrombosis in children from the Children's Hospital of Philadelphia between January 1, 2000, and December 31, 2013, were reviewed. All patients survived to discharge; 3 of 12 (25%) experienced neurologic morbidity. Contrast-enhanced MRI and contrast-enhanced head CT were 100% sensitive for detecting cavernous sinus thrombosis, while noncontrast time-of-flight magnetic resonance venography (TOF MRV) and noncontrast head CT were 0% sensitive. Literature review produced an additional 40 cases, and the aggregate mortality rate was 4 of 52 (8%) and morbidity rate was 10 of 40 (25%). Outcomes did not vary by treatment or with unilateral vs bilateral cavernous sinus involvement. There was a trend toward worse outcomes with fungal infections.ConclusionOur case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed.

Project description:Cavernous sinus angioleiomyoma (ALM) is extremely rare. Only three cases have been reported to be cavernous sinus ALM, and very few reports described characteristic findings for intracranial ALMs in detail. We report a new case of cavernous sinus ALM, with detailed information on the clinical presentation, radiology, pathology, and surgical approach. A 52-year-old woman had a 6-month history of right eye discomfort. Magnetic resonance imaging showed a right cavernous sinus tumor with heterogenous blush enhancement. Enhanced computed tomography scans and angiography showed small nodular enhancement in the tumor. Complete tumor resection was achieved via an extradural temporopolar approach. ALM was identified based on histologic examination. Intracranial ALMs are different from the ALMs that occur in the extremities based on our review of the literature. Intracranial ALMs appear more frequently in men than women. The cavernous type was the most common pathologically, and they occur often in the epiperidural location. Because cavernous sinus ALM occurs in the interdural space, an epidural approach should be selected. Therefore, it is important to include cavernous sinus ALM into a differential diagnosis of a cavernous sinus tumor. The blush enhancement and nodular enhancement within this lesion may be useful to distinguish cavernous sinus ALM from other differential diagnoses.

Project description:BackgroundSchwannomas of the abducens nerve are a rare pathology and are encountered less within the cavernous sinus. We describe a case of sixth cranial nerve schwannoma, in the cavernous sinus.Case descriptionA 50-year-old lady, presented with 2 years history of double vision and left facial numbness that started 6 months before presentation, found to have hyperintense lobulated mass at the left cavernous sinus extending into Meckel's cave with bony remodeling on magnetic resonance imaging. She underwent left frontotemporal craniotomy, combined extra-intradural approach, gross total resection. She had a gradual recovery of the sixth cranial nerve function.ConclusionAbducens nerve schwannoma of the cavernous sinus is a rare and challenging tumor. However amenable to surgical intervention with favorable neurological outcome.

Project description:BackgroundGout is a common metabolic disorder of purine metabolism, causing arthritis in the distal joints of the appendicular skeleton. Spine involvement is rare, and very few cases of spinal gout have been reported. The authors present a rare case of axial gout with tophaceous deposits in the thoracic spinal canal resulting in cord compression and mimicking a meningioma.Case descriptionA 33-year-old male presented with chronic mid back pain and a progressive paraparesis. The presumed diagnosis was meningioma based on MR imaging with/without contrast that showed a posterolateral, right-sided, and T10-T11 intradural extramedullary lesion. Notable, was hyperuricemia found on hematological studies. The patient underwent a decompressive laminectomy (T9-T11) for excision of the lesion, intraoperatively, an intraspinal, chalky, white mass firmly adherent to and compressing the dural sac was removed. The histopathology confirmed the diagnosis of a gouty tophus. Postoperatively, the patient's pain resolved, and he regained the ability to walk.ConclusionA gouty tophus should be included among the differential diagnostic considerations when patients with known hyperuricemia present with back pain, and paraparesis attributed to an MR documented compressive spinal lesion.
