Atypical leiomyoma (AKA symplastic leiomyoma) - leiomyoma with nuclear atypia. Lipoleiomyoma - with adipose tissue. [57] are now understood as ultrastructural variants of GIST [60], based on their histologic and immunohistochemical simi-larity with GISTs, KIT-positivity and occurrence of GIST-spe-cific KIT-mutations. Leiomyoma of the uterus is the most common uterine benign neoplasm and often shows moderately intense 18 F-FDG accumulation . 1 Oral leiomyomas may be seen in any age group with a mean age of occurrence around 41 years. uterine leiomyoma. The tumour includes three distinct entities, leiomyoblastoma, clear cell leiomyoma and plexiform leiomyoma.

Soft fibroma. In a population‐based study of uterine sarcomas from Norway , of 356 tumors classified initially as leiomyosarcomas, the diagnosis was confirmed in only 259 (73%) cases, whereas 97 (27%) were excluded on review and reclassified, according to WHO criteria, as leiomyomas or leiomyoma variants Benign metastasizing leiomyoma. Leiomyoma variants. Leiomyomas are composed of bundles of smooth muscle cells that look very much like those of the normal myometrium. The diagnosis of bland-looking spindle cell lesions of the breast is often challenging because there is a close morphological and immunohistochemical overlap among the different entities. KVAST (Swedish Society of Pathology). However, the distinction between leiomyomas and leiomyosarcomas may at times be problematic. DISCUSSION. A leiomyoma, also known as fibroids, is a benign smooth muscle tumor that very rarely becomes cancer. Atypical uterine leiomyomas show benign behavior. Epidemiology It is thought to occur in up to 60% of uterine leiomyomas 3. The patient was managed as for a benign tumor. Epithelioid leiomyoma is a rare variant of leiomyoma.
