The agony of uncertainty: Smooth muscle tumor of uncertain malignant potential
Dineth Adrienne C Gutierrez
Mary Johnston Hospital, Philippines
S
mooth Muscle Tumor of Uncertain Malignant Potential
(STUMP) is a rare mesenchymal uterine tumor that is
neither benign nor malignant. Its cause and risk factors
remain unknown. Its clinical behavior is unpredictable, and
the cornerstone of management is observation. Presented
is a case of STUMP in a 47-year-old woman who had sought
consult due to abdominal enlargement of two months’
duration. Physical examination revealed a huge pelvo-
abdominal mass extending from the hypogastric area up
to the level of the umbilicus. The patient went into surgery
for what was initially presumed to be a malignant ovarian
new growth. Intra-operatively, however, there was no
visible ovarian pathology. Instead, the uterus was noted to
be enlarged to five months size, with an irregular tumor on
the fundal area measuring approximately 9 x 7 x 5 cm and
invading more than half of the myometrium on cut section.
A post-operative diagnosis of Leiomyosarcoma was made.
However, the final histopathology report revealed a STUMP.
Immunostaining for KI-67 further confirmed the diagnosis.
The patient was advised to follow up after three months
for close monitoring. On follow-up, ultrasound revealed the
presence of an encysted fluid measuring 4 x 4.1 x 3.4 cm at
the left adnexal area. Ultrasound-guided aspiration biopsy
was done, which revealed chronic inflammatory pattern.
The patient was advised to continue regular follow-ups every
six months. This is the first case of STUMP reported at our
institution.
