Tratamento cirúrgico de cisto epidermoide em região submandibular: relato de caso / Surgical treatment of epidermoid cyst submandibular region: case report

Os cistos epidermoides são cistos de desenvolvimento, benignos, cutâneos ou intraósseos, sendo atípicos na face. Podem crescer em qualquer parte do corpo, porém apenas 7% deles estão localizados na região da cabeça e pescoço. Surgem a partir da implantação traumática do epitélio ou aprisionamento de restos epiteliais durante a fusão embrionária. Comumente são lesões assintomáticas, de crescimento lento e, dependendo da extensão, podem causar alterações estéticas significativas. O exame microscópico revela uma cavidade limitada por epitélio escamoso estratificado, similar à epiderme, como também uma camada de células granulares bem desenvolvidas, com o lúmen preenchido por ortoceratina degenerada. O tratamento de escolha é a remoção cirúrgica completa da lesão através da enucleação de toda a cápsula cística. Este artigo tem como objetivo demonstrar o tratamento cirúrgico de um paciente portador de cisto epidermoide em região submandibular, bem como discutir suas características clínicas e cirúrgicas...

Epidermoid cysts are developing cysts, benign, cutaneous or intraosseous, and atypical in the face. They can grow on any part of the body, but only 7% of them are located in the head and neck, and 1.6% occurs in the oral cavity, accounting for 0.01% of all cysts of the oral cavity. These cysts arise from the traumatic implantation of epithelium or entrapment of epithelial debris during embryonic fusion. They are usually asymptomatic lesions, slow growth and depending on the extent can cause significant cosmetic changes. Microscopic examination revealed a limited cavity by stratified squamous epithelium resembling the epidermis, but also a well-developed layer of granular cells, with the lumen filled with degenerated ortoceratina. The treatment of choice is the complete surgical removal with enucleation of the entire cystic capsule. This article aims to demonstrate the surgical treatment of an epidermoid cyst patient with a submandibular region and discuss their clinical and surgical characteristics... (AU)

Trichilemmal cyst in the eyelid:a rare presentation / 国际眼科杂志(Guoji Yanke Zazhi)

A 42-year-old Malay lady presented with a 2-year history of painless and progressive right upper lid swelling. There was no history of trauma or similar lesion elsewhere. An excisional biopsy of the mass was performed and the histopathological findings of the excised lesion were consistent with those for a trichilemmal cyst. Trichilemmal cyst, although rare should be considered in any case of eye lid lesion.

A Case of Scrotal Calcinosis Associated with Pilar Cyst / 대한피부과학회지

Idiopathic calcinosis of the scrotum appears in childhood as multiple, asymptomatic nodules of the scrotal skin that gradually increase in size and number and sometimes discharge a chalky material. Histopathologic examination shows calcific deposits of various sizes that are present in the dermis and often surrounded by foreign body granulomatous inflammation. The pathologic mechanism of this condition is not clear, but there is accumulating evidence for dystrophic calcification of cyst rather than an idiopathic genesis. Here we present a 34-year-old otherwise healthy man who had a 10-year history of multiple, asymptomatic, firm, subcutaneous nodules of the scrotal skin, which sometimes discharged a chalky material. The nodules were completely excised and 45 nodules were observed in the histopathologic examination. In addition to the typical findings of idiopathic calcinosis of the scrotum, seven intact cysts were observed among 45 nodules. Among the seven cysts there were five pilar cysts and two indeterminate cysts with diffusely calcified keratinous content and attenuated walls. A mixture of calcified keratinous material and inflammatory infiltrates was detected. These findings suggest that idiopathic calcinosis of the scrotum may be deriven from the dystrophic calcification of cysts.
