In the current case report, we present a patient with intracranial anaplastic meningioma that presented as a mass on the scalp. Case presentation Figure 1 Figure 2 Figure 1. [escholarship.org]

Rarely, they can present extracranially,[1] where they are accessible to fine needle aspiration cytology (FNAC) and pose a diagnostic dilemma. [ncbi.nlm.nih.gov]

The authors present a case of cutaneous meningioma of the frontal region with an unusual presentation and which could not be included into any of the classical types described. [scielo.br]

• Cervical Lymphadenopathy

  There was no evidence of cervical lymphadenopathy on palpation. [scielo.br]

  There was no evidence of cervical lymphadenopathy on palpation. Further systemic and bilateral breasts examination revealed no abnormality in any of the systems. [ncbi.nlm.nih.gov]

• Asymptomatic

  (a) A slowly growing asymptomatic mass over scalp on the right parieto-occipital region. [ncbi.nlm.nih.gov]

  A 55-year-old male presented with a slowly growing asymptomatic tumoral lesion in the frontal area, which had been evolving for 3 years. [scielo.br]

  In our case, the initial tumor probably developed due to the seeding of meningeal cells of an asymptomatic intracranial meningioma through a post-traumatic defect in the skull or because of seeding of meningeal cells into a post-traumatic meningocele. [ijdvl.com]

• Lymphadenopathy

  There was no evidence of cervical lymphadenopathy on palpation. [scielo.br]

  There was no evidence of cervical lymphadenopathy on palpation. Further systemic and bilateral breasts examination revealed no abnormality in any of the systems. [ncbi.nlm.nih.gov]

• Soft Tissue Mass

  Neurosurgery Department Okmeydanı Training and Research Hospital, İstanbul, Turkey Abstract Meningiomas are tumors of the central nervous system that rarely present as extracranial soft tissue masses. [escholarship.org]

  The mass was completely excised with the intact capsule, and there was no intraoperative bleeding or any other complication. Grossly, a single circular fibrofatty firm soft tissue mass measuring 3.5 × 3 × 0.3 cm was received. [ncbi.nlm.nih.gov]

• Weight Loss

  The patient did not have weight loss or loss of appetite. Her menstrual cycles were normal. The mass had been progressively increasing in size over the last 4 years. [ncbi.nlm.nih.gov]

• Aspiration

  Rarely, they can present extracranially,[1] where they are accessible to fine needle aspiration cytology (FNAC) and pose a diagnostic dilemma. [ncbi.nlm.nih.gov]

• Loss of Appetite

  The patient did not have weight loss or loss of appetite. Her menstrual cycles were normal. The mass had been progressively increasing in size over the last 4 years. [ncbi.nlm.nih.gov]

• Sweating

  On the basis of cytological and histomorphological findings, most epithelial tumors can be easily distinguished by the presence of keratinization and sebaceous or sweat gland differentiation. [ncbi.nlm.nih.gov]

• Alopecia

  Due to its rarity and lack of characteristic clinical features (painless subcutaneous nodules, alopecic areas with tufts of hair or hipertrichosis), the differential diagnosis is quite broad, including nevus sebaceous, alopecia areata, adnexal tumors, [scielo.br]

• Fracture

  We describe the case of a patient who developed a paranasal swelling after head trauma and associated fractures in the same region years before. Histopathological examination of an incisional biopsy revealed the diagnosis of cutaneous meningioma. [cambridge.org]

  Clinical history revealed that there was no trauma or fracture in the past. There was no history of headache or convulsion. The patient did not have weight loss or loss of appetite. Her menstrual cycles were normal. [ncbi.nlm.nih.gov]

• Meningism

  Cutaneous meningioma (also known as "Heterotopic meningeal tissue,"[1] and "Rudimentary meningocele"[1]) is a developmental defect, and results from the presence of meningocytes outside the calvarium.[2]: 622  See also[edit] List of cutaneous conditions [en.wikipedia.org]

  Extracranial meningiomas can develop probably secondary to trapping of meningeal tissue after trauma. If there is no intracranial connection surgical removal can be considered. [cambridge.org]

  In our case, the initial tumor probably developed due to the seeding of meningeal cells of an asymptomatic intracranial meningioma through a post-traumatic defect in the skull or because of seeding of meningeal cells into a post-traumatic meningocele. [ijdvl.com]

  They are derived from arachnoid cells of meninges. Rarely, they can present extracranially,[1] where they are accessible to fine needle aspiration cytology (FNAC) and pose a diagnostic dilemma. [ncbi.nlm.nih.gov]

Technological advances have dramatically improved radiologic imaging and radiotherapy treatments, and further refinements are under investigation. [scienceopen.com]

The gold standard treatment is complete surgical excision, although some advocate conservative treatment if the lesion is asymptomatic and there are no complications.11 Miedema JR, Zedek D. Cutaneous meningioma. [scielo.br]

Genetic predisposition has not yet been established for these lesions; however, Tron et al. and Miyamoto et al. highlighted familial presentation of type I cutaneous meningiomas with autosomal dominant mode of inheritance in their studies.[7,8] Definitive treatment [ncbi.nlm.nih.gov]

Type I lesions have better prognosis than type II and III. Some type III lesions can be inoperable, significantly worsening the vital prognosis. [scielo.br]

Some studies found that cutaneous meningioma Type I has better prognosis. Type III lesions can be difficult to operate leading to poorer prognosis. [ncbi.nlm.nih.gov]

They may be associated with intracranial meningiomas and neurological deficits. [1] They can occur at various sites and are slow-growing tumors with a good prognosis. [2] A 35-year-old man was seen at the outpatient clinic of the department of dermatology [ijdvl.com]

Over recent years, interest in this clinically diverse group of tumors has intensified, bringing new questions and challenges to the fore, particularly in the fields of epidemiology, radiology, pathology, genetics, and treatment. [scienceopen.com]
