“…11 Meningiomas are usually intracranial extra-axial in location, but few rare extracranial variants are also noted. 1 In the 1730s, the first case of extradural meningioma was documented. 2 Extracranial meningiomas can occur due to 1) direct spread of the CNS meningiomas into the surrounding tissues, 2) as metastatic meningiomas or 3) primary ectopic meningiomas.…”

“…They have a propensity to grow even more rapidly following radiotherapy or surgery. 1 Cutaneous heterotopic meningeal nodules, cutaneous meningeal hamartomas, meningothelial hamartomas are described as the variations in cutaneous meningiomas. 7,9,12 Cutaneous meningiomas have been subclassified into three subtypes based on clinicopathological presentation by Lopez et al in the year 1974.…”

“…Associations of cutaneous meningiomas have been found with breast carcinomas, neurofibromatosis and pheochromocytomas. 1,2,12 It is proposed that these tumors grow in presence of increased endogenous steroids like estrogens. 1,2 Hence on diagnosis of CM wherever clinically indicated, further investigation is recommended.…”

“…Meningiomas are the most common intracranial extraaxial neoplasms. 1 They arise from arachnoid cells and are found in the convexities of hemispheres of the parasagittal region. Cutaneous meningomas (CM) are a small subset of meningiomas accounting for less than 2% of cases.…”

Cutaneous meningiomas (CM) are rare variants of meningiomas which are further classified into three subtypes. Type I CM (TICM) or Rudimentary meningocele (RM) is an uncommon developmental anomaly in which meningothelial elements are displaced into the skin and soft tissue. We present a case of 11 year boy with an upper back swelling since early childhood. His MRI spine showed a lesion at T4-T7 level with a fistulous tract connecting it to dural sac. Histopathology revealed clusters of oval to spindle cells arranged in whorls amidst collagen bundles and psammoma bodies. On immunohistochemistry these cells expressed EMA and Vimentin. A diagnosis of TICM was rendered based on these characteristic clinico-radiological & histopathological features. TICM pose a diagnostic challenge clinically and histopathologically and have an excellent prognosis. This is the 4 Indian case of RM and the 1 case of RM to be located in the spine in the Indian literature.

Meningiomas are a type of tumor that arises from meningothelial cells and primarily develops in intracranial space, being some of the most common benign tumors of the central nervous system. However, meningiomas can rarely occur on the scalp and are called primary cutaneous meningiomas. Since the pathogenesis of these lesions is still uncertain, these tumors still pose challenges in terms of histopathological diagnosis. In this review, we will discuss the main cases of scalp meningiomas in the literature, their classification, pathological and immunohistochemical diagnosis, differential diagnosis with other scalp lesions and the most effective treatment. This study highlights the importance of immunohistochemistry in the differential diagnosis of skin lesions located on the scalp.
