Triple synchronous primary malignancies of the colon, endometrium and kidney in a patient with Lynch syndrome treated via minimally invasive techniques
Gynecol Oncol Rep. 2016 Aug; 17: 29–32.
Published online 2016 May 251. Introduction
Synchronous
primary tumors of the female reproductive tract are not rare
conditions. Double primary malignancies have been extensively studied,
with the most frequent synchronous neoplasms being endometrial and
ovarian cancers. Triple primary malignancies, on the other hand, are
very rare and it is necessary to distinguish the malignancies as primary
versus metastases. To our knowledge, there have been few studies in the
literature that demonstrate the existence of triple simultaneous
neoplasms (Isin Dogan Ekici et al., 2006, Hale et al., 2011, Takatori et al., 2014, Phupong et al., 2007, Ozan et al., 2008, Capilna et al., 2014).
In
this report, we identify and present the findings from a patient with
synchronous endometrial carcinoma, renal cell carcinoma and mucinous
adenocarcinoma with signet ring cell features of the colon. We believe
this to be the first report of this histological combination of
malignancies. Genetic testing of the patient was positive for a
deleterious mutation in MSH6, suggestive of Lynch syndrome. A
multidisciplinary surgical approach helped our patient have combined
procedures done via minimally invasive approaches at one sitting with
excellent surgical outcomes.
2. Case
A
60-year-old, Hispanic female gravida 3 para 3 postmenopausal female
presented with symptoms of abdominal pain, bloating, flatulence,
diarrhea and urinary frequency and postmenopausal bleeding. She was
referred by her gynecologist after endometrial biopsy showed moderately
differentiated endometrial adenocarcinoma. On preoperative PET imaging (Fig. 1)
she also had a 6 cm right upper pole renal mass that was suggestive of
renal cell carcinoma and a lesion in the transverse colon seen at the
time of colonoscopy consistent with either a primary malignancy or
metastatic disease. The patient had no significant medical or
gynecologic history and a BMI of 26.3. Her family history was
significant for an uncle with colon cancer (age 60), a sister with
ovarian cancer (age 45), her mother had breast (age 33) and uterine
cancer (age 60) and a grandmother with uterine cancer (age 50). Until
now, no other family member had been tested for any hereditary cancer
mutations.
