Abstract Cutaneous meningiomas are rare tumors most commonly located on the scalp. We report the case of a 55-year-old male who presented with a 2x3 cm tumoral lesion on the forehead. The lesion was hard, adherent and covered by normal skin. Incisional biopsy revelead a proliferation of monomorphic round cells, organized in nests and focally forming pseudovascular spaces. Immunohistochemical study revealed positivity for epithelial antigen membrane and vimentin. Vascular markers, cytokeratins and S100 protein were negative. A brain CT scan did not show any evidence of intracranial meningioma. The authors describe the case of a cutaneous frontal meningioma in probable relation with previous cranioencephalic trauma.

A escabiose ou sarna humana é uma infestação cutânea intensamente pruriginosa causada por Sarcoptes scabiei var hominis. A sarna crostosa (previamente conhecida como sarna norueguesa) é uma forma rara, muito contagiosa e transmitida pelo contacto direto com a pele. Apesar de eficazmente tratável, um atraso no diagnóstico leva muitas vezes ao contágio e infestação dos contactos, o que dificulta a contenção dos surtos. Apresentamos o caso de um doente onde os achados dermatoscópicos (sulcos escabióticos e estruturas em asa delta), confirmados pelo exame parasitológico direto, permitiram um rápido diagnóstico, reforçando o papel crescente que esta técnica assume na prática clínica.

Human scabies is an intensely pruritic skin infestation caused by Sarcoptes scabiei var. hominis. Crusted scabies (previously known as Norwegian scabies) is a rare form, very contagious and transmitted by direct contact with the skin. Despite being readily treatable, a delayed diagnosis often leads to widespread infestation of contacts, and therefore difficult to restrain. This case concerns a patient where dermoscopy (with scabetic burrows and a visible hand-glider structure), together with direct microscopic examination, allowed a prompt diagnosis, thereby reinforcing the increasing importance of this technique in daily practice.
