Materials and methods: histological, immunohistochemical, statistics. The study was 
conducted on 71 samples of fallopian tubes tumor tissue. 
Results and discussions. PCFT more commonly affect the postmenopausal women, aged 60-
69 years, mainly in early stages of the disease (I-II) (60.8%) and in most cases is represented as serous 
adenocarcinoma (92.96%).It was determined that most of them are receptor-positive for both steroid 
receptors (ER – 83.33%, PR – 62.12%). But the receptor profile of the tumor of the fallopian tubes 
did not depend on the age. When the tumor differentiation grade becomes lower the number of 
receptors for steroid hormones also reduces.High level of proliferative activity is typical for this type 
of neoplasia and it doesn’t depend on the age, stage of the disease and tumor differentiation grade. 
Ki-67 expression is independent marker for N-status and helps to determine the patients who are in 
the "risk" group.HER-2/neu expression is not typical for PCFT, taking into account almost complete 
lack of it (only 9% – doubtful reaction) in tumor tissue. 
Conclusions. Study of immunohistochemical status showed relatively high expression of 
steroid hormone receptors, high expression of Ki-67, that can give rise to offer patients with this type 
of neoplasia destination targeted therapy that blocks the growth and spread of cancer cells by affecting 
the specific molecules involved in the growth and the development of a tumor cell. 
 
 
SYNDROME MERMAID - SEVERE SYNDROME OF CAUDAL REGRESSION

Congenital limb malformations rank behind congenital heart disease as the most common birth 
defects observed in infants. The term «sirenomelia» («mermaid syndrome») is derived from the 
physical similarity of the affected fetus to mythical creatures mermaids - charming women with the 
lower part of the body in the form of a fish tail, where there is a fusion of the lower extremities and 
partial or complete fusion of the feet.  
The aim of the present study is to assess the significance of the study of museum specimens allowing 
to tracemermaid syndrome in part of the museum collection of the Department of Pathological 
Anatomy of Kharkiv National Medical University devoted to prenatal and perinatal pathology as one 
of the most representative among the academic collections in the world.  
Subjects and Methods.The study implied literature search and the assessment of macroscopic 
preparations of the museum of Department of Pathological Anatomy at KhNMU dedicated to pre-
and perinatal pathology with congenital malformations. 
Results. The syndrome of the mermaid is a very severe form of the syndrome of caudal regression 
(complex malformation the caudal portion of the embryo), which, in turn, is a rare severe congenital 
malformation of the distal spine and spinal cord (his clinical picture is accompanied by hypoplasia of 
the lower half of the trunk and extremities, fusion of the lower limbs). Fusion can be within the bone 
or soft tissues only. There are renal agenesis, blindly ending colon, the lack of external and internal 
genitalia, single umbilical artery atresia of the anus in most cases of sirenomelia. Sirenomelia is 
almost always a fatal disease because birth defects named above. Approximately 50% of infants with 
this diagnosis are stillborn. Violation of the blood supply leads to the disturbance of tissue 
differentiation in that area and so severe defects. Prognosis is very poor because of the condition 
involves variable major anomalies, including bilateral renal agenesis, sacral agenesis and imperforate 
anus. Only four cases of a surviving infant with sirenomelia have been reported. The death of a child 
usually occurs during the first hours and days of life. The cause of death is lung hypoplasia and renal 
failure.
