    Malignant Transformation of Endometriosis: A Rare Case of Extrauterine Endometrial Stromal Sarcoma. (PubMed, Ann Afr Med)
    This rare case highlights that existing chronic endometriotic lesions have the potential to transform into malignancy, and clinicians must be aware of this. Clinical manifestation and radiological features of ESS are the same as endometriosis and diagnosis is based on histopathological evaluation.

    Dexamethasone Suppresses Already Low Estrogen Receptor Levels in Meningiomas. (PubMed, Int J Mol Sci)
    The difference in intra-tumoral estrogen concentration is proposed as a potential cause for lower ER in ICM. Replacement of Dex and more sensitive ER assays are needed to determine the role of hormones in the causation and treatment of ER+ ICM.
