Case 1
Submitted by: Anais Malpica University of Texas MD Anderson Cancer Center, Houston, TX
Clinical Summary:
A 63 year-old female with a previous history of a total abdominal hysterectomy and bilateral
salpingoophorectomy for uterine leiomyomas presented to the emergency room with diffuse abdominal pain.
Imaging studies including CT scan of the abdomen and pelvis were normal. The patient underwent a
colonoscopic examination that was unremarkable and was given treatment for her symptoms. The abdominal
pain persisted and a second CT scan of the abdomen and pelvis performed three months later showed a 9 cm
mass in the right lower quadrant. The patient underwent exploratory laparotomy, resection of the mass,
and omentectomy.

Clinical Summary:
Case identification: J136-96
A previously healthy 44-year old woman presented with low back pain. X-ray showed a calcified mass
beside the left kidney, measuring 5.5 cm. After an observation period of 6 months showing no appreciable
change in the size of the tumor, laparotomy was performed. The mass was situated in front of the upper
pole of left kidney and left adrenal gland, from which it could be separated and excized. The patient
made an uneventful recovery.

Submitted by: Mahul B. Amin Emory University Hospital Atlanta, GA
Clinical Summary:
A 25-year-old female presented with dysuria and hematuria and was treated empirically with antibiotics
for urinary tract infection. Her symptoms progressively worsened, and 2 weeks later she presented again
when an ultrasound (Figure 1) showed a large intravesical mass. A transurethral resection was
performed, a diagnosis was rendered at one institution. She later had an uneventful pregnancy without
any complications. A month after the delivery, she presented to her urologist for a rapidly growing
painful mass that protruded through the urethral meatus. Submitted sections are from the large mass
(Figure 2) resected from the urethra. Representative microscopic figures (Figures 3-8).
