Squamous cell carcinoma arising from longstanding colocutaneous fistula: a case report.
ABSTRACT A 60-year-old female patient suffered unhealed wounds over left flank for around 30 years after surgical removal of left renal stones. Fecal material spilled from the two small openings of the scar, bothered her all day long. During the course of the 30 years, she suffered from intermittent fever, diarrhea and wound pain and presented with malnourished condition. After serial examinations, tumor associated with iatrogenic colo-cutaneous fistula was impressed and she received en bloc resection. Pathology revealed squamous cell carcinoma arising from the fistula with colon and spleen invasion. To the best of our knowledge, no such case has been reported, as yet.

ABSTRACT: AIM: To investigate the sequential changes of body composition in the metabolic response that occurred in a group of patients with enterocutaneous fistula after admission to the hospital. METHODS: Sixty-one patients with enterocutaneous fistula admitted to our hospital had measurements of body composition by multiple-frequency bioelectrical impedance analysis after admission and 5, 10 days later. Sequential measurements of plasma constitutive proteins were also made. RESULTS: The body weight, fat-free mass, body mass index, and body cell mass were initially well below the normal range, especially the body mass index and body cell mass. And all the data gradually moved up over the 10-day study period, only a highly significant difference was found in body cell mass. Once the patients received nutrition supplement, ECW began to return to normal range slowly as well as ICW and TBW began to rise up, and ECW/TBW significantly declined to near normal level by day 10 in either male or female patients. There was a reprioritization of plasma constitutive protein synthesis that was obligatory and independent of changes in FFM. CONCLUSION: Serial measurements can quantify the disturbance of body composition in enterocutaneous fistula patients. The early nutritional intervention rapidly ameliorates the abnormal distribution of body water while the state-of-the-art surgical management prevents the further deterioration in cellular composition.World Journal of Gastroenterology 01/2002; · 2.55 Impact Factor

ABSTRACT: The case of a woman who had had a perianal sinus tract for nine years, in whom squamous-cell carcinoma arose in the sinus tract, is presented. We believe that long-standing perianal sinus tracts should be examined carefully for tumor development. In suspected cases, a biopsy specimen should be obtained from the central part of the lesion.Diseases of the Colon & Rectum 01/1975; 18(5):416-7. · 3.34 Impact Factor

Malignant tumors arising from previously existing fistulas
are rare. Squamous cell carcinoma arising from colocutaneous
fistula has never been reported. Herein, we report a case
of squamous cell carcinoma arising from previously existing
longstanding colocutaneous fistula. The diagnosis made
has been based on high suspicion, history, imaging and
CASE REPORTCASE REPORT
CASE REPORT CASE REPORT
A 60-year-old female patient was admitted due to general
weakness, anorexia accompanied with fever and chills for
2 wk. She denied any other systemic disease. The patient
originally was diagnosed with left renal stones and had left
nephrectomy, at some other hospital three decades ago.
She got stool spillage from surgical wound on left flank
after that surgery. Despite wound treatment, two fistulous
openings were left with intermittent fecal discharge. During
this period, she received supportive treatment while infective
symptoms such as fever, chills, diarrhea and local cellulites
We noted that she was a cachectic, frail female with pale
conjunctivae. The abdomen was palpated without tenderness
and the bowels were normally peristaltic on auscultation.
Two chronic unhealing wounds involving the left flank with
fecal discharge were noted (Figure 1A). Local erythematous,
swollen and tender to palpated were noted. No enlarged
lymph nodes were palpated. Anemia (Hb 4.4 g/dL) and
chronic renal insufficiency (Cr 2.3 mg/dL) were noted.
Abdominal computed tomography discovered splenomegaly
with soft tissue density adjacent to it and the splenic flexure
of T-colon with air bubbles (Figure 1B). After infection
had subsided, fistulograms revealed communication between
skin and bowel tract (Figures 1C and D). Under a period of
nutritional support, surgical intervention was performed.
At laparotomy, the low pole of the spleen adhered to the
splenic flexure of T-colon densely with irregular soft tissue
beside the region (Figure 1E). Partial wall of the jejunum, 10
cm distal to Treitz’s ligament, adhered to the distal T-colon
was noted (Figure 1F). En bloc resection with splenectomy,
segmental resection of colon with primary anastomosis and
wedge resection of jejunum were performed (Figure 1G).
Postoperative course was grossly smooth. She is being
followed up at the outpatient department.
The pathologist reported moderately differentiated squamous
cell carcinoma in virtually all specimens (Figure 2A).
However, the microscopic photographs revealed the tumor
cells arising from the fistulas (Figure 2B) with spleen (Figure 2C)
and colon invasion (Figure 2D).
It is well-known that surgery is still the most common
cause of entero-cutaneous fistula. The causes of persistent
entero-cutaneous fistula include foreign body, radiation,
infection, inflammation, epithelization, neoplasm and distal
obstruction. Squamous cell carcinoma can develop from
chronic ulcers, scars, wounds, sinuses, and fistulas. The
latent periods are long and take around 37 years for patients

with burn scars except 1-7 years for immunocompromised
patients[2,3]. The most significant factor reported in predicting
the outcome for the squamous cell carcinoma from the
pre-existing scar or sinus was the grade of the tumor.
Squamous cell carcinoma associated with prior renal stones
have always been reported and the median survival time
was 3.6 mo. It was dismal and was not compatible with
the long-term history of the patients. We might consider
Lee YT et al. SCC arising from colocutaneous fistula 5253
the development of squamous cell carcinoma as the result
of chronic irritation and infection due to unhealed wounds.
The strong evidence was that the microscopic photographs
revealed the origination of tumor cells from the epithelium of
the fistulous tract. However, there are no prior reported articles
available as this case. Because of its insidious course, the long-
standing colo-cutaneous fistula should be examined carefully
for tumor development. The early nutritional intervention
is important for patients with entero-cutaneous fistula and
surgery is inevitable for long-term unhealed fistula.
