ABSTRACT
The science about the usage of face masks by the common public to avert COVID-19 transmission is proceeding swiftly. A primary route of transmission of COVID-19 is probably through small respiratory droplets, and it is transmissible from asymptomatic and pre-symptomatic individuals. According to the World Health Organization, wearing a mask in public can help reduce the transmission of the COVID-19 virus. Different categories and types of masks and their usage are reviewed in this work. In a nutshell, this review work elucidates the aspects of utilizing the various face masks along with all possibilities to fight against the ongoing pandemic of COVID-19.
ABSTRACT
Intracranial fibrous histiocytomas are rare; Benign Fibrous Histiocytoma (BFH) being uncommon than its malignant counterpart. BFH comprises fibroblasts and histiocytes without any nuclear pleomorphism or atypia. We present a case of a 42-year-old male who had swelling over the occipital region for the past five years, which progressively increased in size. He developed headache, dizziness, and gait disturbance over the last six months. Computed tomographic scan revealed a posterior fossa space-occupying lesion. Fine-needle aspiration cytology from the swelling revealed spindled fibroblasts along with histiocytes and multinucleated giant cells. Later, histopathology showed presence of spindle-shaped cells in storiform pattern admixed with histiocytes and giant cells. The giant cells and histiocytes were immunopositive for CD68 and spindled cells were positive for vimentin, but immunonegative for CD34, epithelial membrane antigen, CD1a and S100. The final diagnosis was intracranial BFH. We present this case because of its extreme rarity and unusual location.
