Pregnancy-Related Precancerous Cervical Lesions: Pathogenesis, Diagnosis, Evolution, and Impact upon Gestation and Fertility.

More common than cervical cancer, cervical intraepithelial neoplasia (CIN) represents a precursor lesion of cervical carcinoma, being associated with HPV infection. Due to the bidirectional relationship between HPV and estrogen and progesterone in pregnancy, most of the published data claim that precancerous lesions remain stable or even regress during pregnancy, although several studies have indicated the tendency of HSILs to persist. It is considered that pregnancy-related cervical precancerous lesions undergo a postpartum regression, due to stimulatory effects of the immune microenvironment.

The significance of immune microenvironment in patients with endometriosis.

Endometriosis represents an estrogen-dependent disease of the female reproductive system and intra- and extraperitoneal regions, with chronic feature. Currently, immune cells, such as macrophages and lymphocytes, are considered to play a pivotal role in angiogenesis and invasion of endometriotic cells through matrix remodeling. Additionally, various studies have revealed the role of E-cadherin, β-catenin, along with steroid hormone receptors in endometriosis development.

Spongiotic reaction patterns in autoimmune bullous dermatoses (Review).

Spongiosis or a spongiotic reaction pattern is the histological hallmark of intercellular epidermal edema, viewed as clear spaces within the epidermis. Although considered a histopathological term, spongiosis has clinical correlations, with the variable degrees of spongiotic reaction leading to different dermatological findings. This review aimed to highlight the spongiotic reactive patterns found in different autoimmune bullous dermatoses, considering the paucity of publications in this domain.
