Synopsis The nail plate is the permanent product of the nail matrix. Its normal appearance and growth depend on the integrity of several components: the surrounding tissues or perionychium and the bony phalanx that are contributing to the nail apparatus or nail unit. The nail is inserted proximally in an invagination practically parallel to the upper surface of the skin and laterally in the lateral nail grooves. This pocket‐like invagination has a roof, the proximal nail fold and a floor, the matrix from which the nail is derived. The germinal matrix forms the bulk of the nail plate. The proximal element forms the superficial third of the nail whereas the distal element provides its inferior two‐thirds. The ventral surface of the proximal nail fold adheres closely to the nail for a short distance and forms a gradually desquamating tissue, the cuticle, made of the stratum corneum of both the dorsal and the ventral side of the proximal nail fold. The cuticle seals and therefore protects the ungual cul‐de‐sac. The nail plate is bordered by the proximal nail fold which is continuous with the similarly structured lateral nail fold on each side. The nail bed extends from the lunula to the hyponychium. It presents with parallel longitudinal rete ridges. This area, by contrast to the matrix has a firm attachment to the nail plate and nail avulsion produces a denudation of the nail bed. Colourless, but translucent, the highly vascular connective tissue containing glomus organs transmits a pink colour through the nail. Among its multiple functions, the nail provides counterpressure to the pulp that is essential to the tactile sensation involving the fingers and to the prevention of the hypertrophy of the distal wall tissue, produced after nail loss of the great toe nail.

“…There is pain upon pressure, sometimes the slightest pressure of even a good shoe. Differential diagnosis is that of all tumors that may occur peri‐ or subungually, namely, warts, pyogenic granulomas, glomic tumors, squamous‐cell carcinomas, malignant melanomas, chondromas, Koenen tumors, sarcomas, angiokeratomas, and keratoacanthomas. Definitive diagnosis is made by radiography.…”

RESUMO Introdução: O tumor glômico é uma lesão neoplásica benigna, geralmente única, que se forma no glomo terminal. Esta estrutura é uma anastomose arteriovenosa subcutânea distribuída por toda a superfície corporal, em particular nos leitos ungueais, polpas digitais, palmas das mãos e plantas dos pés. Apesar da sua raridade, recebe atenção especial por seus sintomas caracterizados por dor paroxística, sensibilidade à pressão do local, ao frio e por sua localização típica na ponta do dedo. O diagnóstico inicial é raramente feito, levando os pacientes a apresentarem os sintomas por meses e até anos, sem o diagnóstico e tratamento adequados. Objetivo: O objetivo desse trabalho é evidenciar o método diagnóstico clínico e histopatológico do tumor glômico, e a utilização da microscopia em seu tratamento cirúrgico. Resultados: Observou-se grande diminuição nos casos de recidiva, com retorno funcional do órgão acometido e melhora da saúde física, funcional e psicossocial do paciente. Conclusão: A exérese do tumor mostrou-se eficaz e os resultados foram plenamente satisfatórios, não havendo complicações pós-operatórias significativas, nem recidivas até o momento.Descritores: Tumor glômico/cirurgia.
