Recurrent subcutaneous metastasis of a convexity meningioma: a case report and literature review.

Subcutaneous metastasis in the operative route after intracranial meningioma resection is extremely rare. Here we describe the case of a 69-year-old male who was operated on in our department for a convexity meningioma that spread a few years after surgery in the soft tissues next to the craniotomy site. Twenty-one other cases have been found in the medical literature. In this article, we discuss mechanisms of growth, presentation and management of subcutaneous meningiomas.

Intramedullary spinal cord tumors: A retrospective multicentric study.

CONTEXT: Intramedullary tumors are neoformations taking part on the spinal cord, and they are a rare pathology. Due to the rarity of such lesions, clinical studies take years to ensure a decent feedback with a significant number of cases. DESIGN: Our study is retrospective and descriptive. PARTICIPANTS: We share a Tunisian multicentric experience of 27 years through a retrospective study of 120 cases of spinal cord tumors that have been operated in six different centers. OUTCOME MEASURES: The clinical, radiological, and histological findings have been analyzed along with postoperative results and tumoral progression so that we could conclude to some factors of prognosis concerning the management of these tumors. RESULTS: The mean age of our patients is 33.84 years. We had 57 males and 63 females. The most frequent revealing symptom was motor trouble presented as frequent as 77.5% of the patients. Glial tumors were represented in 81 of the cases (67.5%) and nonglial by 39 cases (32.5%). Glial tumors we found were essentially 39 ependymomas and 35 astrocytomas. Surgical resection is key in the management of these lesions; the quality of tumoral resection was a significant factor of disease progression as subtotal resection is correlated to more important progression than total one. CONCLUSION: We conclude this work with some statements. In terms of functional results, age is not a significant factor. Presurgical functional state, the histological type, and the extent of surgical resection are the important factors.

Vertebral solitary bone plasmacytoma in a young adult with Trisomy 21: A case report.

Context: Solitary bone plasmacytoma (SBP) are rare lesions, accounting for less than 5% of all plasma cell proliferations. We describe a case of a 21-year-old female with Trisomy 21 presenting with cauda equina compression from an SBP. Findings: Solitary bone plasmacytoma (SBP) is a rare primary bone tumor. It is characterized by monoclonal proliferation of malignant plasma cells localized to a bone segment, without signs of systemic invasion. The vertebral location is the most common. It preferentially affects men during their 5th or 6th decade. Clinical relevance: We report the first association between solitary bone plasmacytoma and Trisomy 21.
