Case Report

dilemma: rare association with focal segmental
glomerulonephritis and cardiomyopathy

INTRODUCTION
Placental site trophoblastic tumor (PSTT) is a rare form
of gestational trophoblastic disease arising from invasive
intermediate gestational trophoblasts and constitutes 1 to
2% of all GTN.
1
It was considered a benign lesion until
Scully and Young recognized its malignant potential in
1981.
2
Due to its relatively slow lymphatic spread and chemo
resistant nature, metastatic lesions to brain or kidneys
often pose a diagnostic dilemma.
The association of PSTT with kidney diseases is very
rare. World over, there are only a handful of cases which
report its association with Lupus Nephritis, thrombotic
microangiopathy (TMA) membranous
glomerulonephritis.
3
However, here we report one of first
few cases of PSTT associated with focal segmental GN.
CASE REPORT
A 20 year old female presented with 2 months
amenorrhea with complain of lower abdominal pain since
20 days. She has Full term vaginal delivery one and half
year back after which she had resumed her regular
menses.
UPT done was positive and USG showed changes of
Vesicular Mole with multiple uterine fibroids. However,
her B HCG was only 179.3 IU/L which was very low to
support any intrauterine or molar pregnancy. Her pelvic
examination was normal and routine lab tests showed
only hypoproteinemia, Mild anaemia and mildly raised
ESR. Clinically, she had minimal ascites.
Dilatation and Evacuation was done. Thereafter B HCG
value was 129.6 IU/L. Histopathological diagnosis
revealed placental Site reaction.
ABSTRACT
Placental site trophoblastic tumour (PSTT) is the rarest form of Gestational trophoblastic neoplasia (GTN).It has a
wide clinical spectrum of presentation and its complications have a multi organ involvment. Inspite of the advances in
HCG assays and sensitive unltrasounds, its diagnosis and course in every case is a mystery. However, it is only rarely
associated with glomerulonephritis. Most cases have not been biopsied and the specific nature of renal involvement is
not clearly understood. Here we report a case of PSTT with glomerulonephritis and cardiomyopathy.
