ABSTRACT
Abstract Purpose Cotyledonoid dissecting leiomyoma is a leiomyoma variant exhibiting unusual growth patterns. We aimed to demonstrate this, as well as to point out another feature that has not been previously reported. Case Report A congested, multinodular myomectomy specimen was resected. Histologically, smoothmuscle fascicles with marked vascularity and extensive hydropic degeneration were detected. A total of 2 mitoses per 10 high power fields were counted, and the Ki-67 index was of 2-3%. We encountered atypical bizarre cells that have not been previously reported. Coagulative necrosis was not present. The patient was alive and well 36 months after surgery, with no evidence of recurrence. Conclusions Albeit the gross aggressive appearance, cotyledonoid dissecting leiomyomas are benign in nature. To this day, atypical cells have not been reported in this type of tumor. Despite the presence of symplastic features, cotyledonoid dissecting leiomyomas are clinically benign entities. Surgeons and pathologists should be acquainted with this variant.
RESUMO
Resumo Introdução O leiomioma dissecante na forma cotiledonoide é uma variante de leiomioma com padrões raros de crescimento. Além de demonstrá-los, vamos apontar outro aspecto anteriormente não relatado. Relato de Caso Uma amostra congestionada, multinodular de miomectomia foi excisada. Histologicamente, detectaram-se fascículos de músculos lisos com marcada vascularidade e extensa degeneração hidrópica. Contaram-se 2mitoses por 10 campos de alta potência, e o índice Ki-67 foi de 2-3%. Encontramos células atípicas, bizarras, que não haviam sido relatadas anteriormente. Não foi observada necrose coagulativa. A paciente encontrava-se saudável e sem evidências de recorrência 36 meses após a cirurgia. Conclusão De aparência bruta e grosseira, os leiomiomas dissecantes na forma cotiledonoide têm natureza benigna. Até hoje, células atípicas não haviam sido relatadas nesse tipo de tumor. Apesar dos aspectos simplásticos, os leiomiomas dissecantes na forma cotiledonoide são entidades clínicas benignas. Cirurgiões e patologistas devem estar familiarizados com essa variante.
