Background: the clear cell adenocarcinoma (CCA) in cervix is a rare disease. It represents only 2 to 7 % of whole adecocarcinomas of cervix. Its histological pattern seems identical to their counterparts elsewhere in the female genital tract, including the vagina, endometrial and ovary. The CCA is constituted by cells with a clear cytoplasm in tack that are arranged in a solid pattern, tubu-locystic, papillary, or mixed.
Clinical Case: an eleven year old girl with sporadic and intermittent transvaginal bleeding, and who felt in severe anemia due to hiperpolimenorrea treated with athinyl estradiol deso-gestrel was attended. She had not history of exposition in utero to diethyletilbestrol. Hysteroscopy showed an ectocervical exophytic lesion in a barrel of 7 × 3 × 3 cm, located predominantly in the posterior lip. A frozen section of the lesion was reported as a poorly differentiated malignant tumor compatible with cervical carcinoma. She underwent to simple trachelectomy.
Conclusions: diagnostic difficulty was the age of the patient and the lack exposition in utero to DES, the differential diagnosis included the age group tumors and rhabdomyosarcoma botryoides and extragonadal endodermic origen with papillary and reticular pattern. Another was a metastatic CCA.

Oestrogen plays a crucial physiological role in both women and men. It regulates reproductive functions and maintains various non-reproductive tissues through its receptors, such as oestrogen receptor 1/oestrogen receptor α (ESR1/Erα), oestrogen receptor 2/oestrogen receptor β (ESR2/Erβ), and G protein-coupled oestrogen receptor 1 (GPER). This hormone is essential for the proper functioning of women's ovaries and uterus.

Article Synopsis
- The study evaluates seroprotection rates against vaccine-preventable diseases in HIV-exposed (HEU) and unexposed (HUU) infants in Malawi to identify at-risk populations.
- Blood samples from 62 infants revealed similar antibody levels against Hib, HBV, and Spn in both groups, with a concerning percentage showing incomplete vaccination.
- Results highlight the need for improved participation in immunization programs, as only about 60% of infants from both groups showed protection against all three diseases.

Immunosuppressive drugs are essential for transplant recipients, since they prolong proper function of graft; however, they affect the morphology and function of organs, including liver. One commonly observed alteration in hepatocytes is vacuolar degeneration. Numerous medications are contraindicated in pregnancy and breastfeeding, mostly due to a lack of data concerning their advert effects.
