A rare cystic lymphoplasmacyte-rich meningioma: A case report and review of the literature.

BACKGROUND: Meningiomas are common central nervous system neoplasms, accounts for 30% of all primary intracranial neoplasms; the occurrence of meningiomas with cystic lesions is an exceptionally rare. Lymphoplasmacyte-rich meningioma (LPRM) is a rare pathological entity belong to the World Health Organization Grade I meningiomas. LPRM is characterized by abundant lymphoplasmacytic infiltrates which over-shadow the underlying meningothelial component. CASE DESCRIPTION: A 42-year-old male was admitted to our hospital with a chronic headache for about 3 weeks prior to admission. His symptoms worsen, and subsequently, he experienced left extremities weakness about 1 week before admission. His brain magnetic resonance imaging revealed an irregular and heterogeneously enhancing solid lesion with intratumoral cystic changes at the temporal lobe. A gross total resection was performed; pathological examination revealed a cystic LPRM. CONCLUSION: This rare variant of meningioma is a benign tumor entity featured with massive inflammatory cell infiltration and often less proportion of meningothelial elements. Surgical resection remains the treatment of choice. This is the first report regarding cystic LPRM from Indonesia; we also summarized relevant literature upto-date, May 2020, reported LPRM cases.

Giant cell angiofibroma of the scalp: A benign rare neoplasm with bone destruction.

BACKGROUND: The incidence of extraorbital giant cell angiofibroma (GCA) is rare, with only one case located in the scalp reported in the literature. The morphological hallmark is histopathological examination showing richly vascularized pattern-less spindle cell proliferation containing pseudovascular spaces and floret-like multinucleate giant cells. CASE DESCRIPTION: We report a case of a 30-year-old female with a primary complaint of a painless solitary nodule arising on the left parietal region of the scalp. Complete tumor removal through surgical intervention was achieved, and the postoperative period was uneventful. CONCLUSION: Diagnosing a highly vascularized tumor in the head and neck is challenging. Our case is unique in that it is presented as a GCA of the scalp, which is an extremely rare clinical entity, and also demonstrated bone destruction.
