고령 남성의 허벅지에 발생한 전형적인 임상 양상의 저등급 섬유점액육종 1예

Low-grade fibromyxoid sarcoma (LGFMS) is a rare malignant tumor that typically manifests as a painless, slow-growing mass in the deep soft tissues of the proximal extremities or trunk. While commonly occurring in young adults, it rarely presents in older individuals. LGFMS is characterized by seemingly benign histological features and a paradoxically aggressive clinical course. LGFMS often exhibits alternating fibrous and myxoid areas arranged in a spiral pattern, featuring benign fibroblast spindle cells. Despite its low-grade appearance, LGFMS has the potential for late metastasis. Diagnosing LFGMS can be challenging owing to its indolent growth pattern and benign appearance on small biopsy specimens, which may lead to confusion with benign soft-tissue tumors. Differential diagnosis of myxofibrosarcoma and myxoid neurofibromas is required. Surgical excision with wide margins is recommended for LGFMS management. We report a typical case of LGFMS located on the right inner thigh of an 82-year-old male.
Three Cases of Vulvar Squamous Cell Carcinoma Arising from Lichen Sclerosus

Vulvar lichen sclerosus (LS) is a chronic inflammatory dermatosis and is considered a precursor lesion of squamous cell carcinoma (SCC); with about 3% to 5% of cases progressing to SCC, even up to 7%. LS can be found in adjacent areas in more than 60% of cases of vulvar SCC. As a chronic scarring inflammatory dermatosis, vulvar LS can act as both an initiator and promoter of carcinogenesis. All suspicious lesions should be biopsied. Although the association between LS and SCC has been reported in the literature, actual case reports are rare in South Korea.
