A Huge Hemorrhagic Epidermoid Cyst of the Perineum with Hypoechoic Semisolid Ultrasonographic Feature Mimicking Scar Endometriosis.

Medicina (Kaunas) 2021 Mar 17;57(3). Epub 2021 Mar 17.

Department of Obstetrics and Gynecology, Chung-Ang University Hospital, Chung-Ang University College of Medicine, 102, Heukseok-ro, Dongjak-gu, Seoul 06973, Korea.

Epidermoid cysts are small, solitary, and slow-growing lesions that rarely appear in the perineum and mostly arise because of trauma. This study examined a huge perineal epidermoid cyst that slowly grew over eight years in a premenopausal woman. Ultrasonography showed that the hemorrhage in the cyst was a semisolid hypoechoic mass, which mimicked endometrioma, and was tentatively diagnosed as scar endometriosis in the perineum after vaginal delivery.

Changes in Cellular Regulatory Factors before and after Decompression of Odontogenic Keratocysts.

J Clin Med 2020 Dec 24;10(1). Epub 2020 Dec 24.

Department of Oral & Maxillofacial Surgery, College of Dentistry, Yonsei University, 50-1 Yonsei-Ro, Seodeamun-Gu, Seoul 03722, Korea.

Decompression followed by enucleation, which is one of the treatments used for odontogenic keratocysts (OKCs), is frequently used in OKC lesions of large sizes. This method offers the advantage of minimizing the possibility of sensory impairment without creating a wide-range bone defect; moreover, the recurrence rate can be significantly lower than following simple enucleation. This study aimed to assess the changes in histology and expression of proliferation markers in OKCs before and after decompression treatment. Read More
