Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder, characterized by the triad of vascular malformations (angioma), venous and or lymphatic malformations and asymmetrical disturbed growth of soft tissues and/or bone. Primary rectal linitis is a rare digestive tumor with very poor prognosis. We report the case of a 41-year-old patient with Klippel trenaunay syndrome who was diagnosed with primary rectal linitis.

Introduction

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder, characterized by the triad of vascular malformations (angioma), venous and or lymphatic malformations and asymmetrical disturbed growth of soft tissues and/or bone [1]. The presence of two of these elements makes the diagnosis possible [2]. Rectal linitis is a rare digestive tumor, most often found in association with gastric localization [3]. Its primitive character is much rarer [3]. Often metastatic at the time of diagnosis, its treatment is a real issue [4]. We report the case of a 41-year-old patient with KTS who was diagnosed with primary rectal linitis (PRL).

Case Report

We report the case of Mrs. O.L., 41 years old, referred for recurrent hematochezia with chronic constipation and difficulties of exoneration. She reported no abdominal pain or weight loss. Flat angiomas of the left back, left breast, chest and abdomen were found, associated with hypertrophy of the left hemi-body responsible for asymmetry (Figure 1-5); which allowed us clinically to make the diagnosis of KTS. At rectal examination, a stenosis at 3 cm from the anal margin was found, partially admitting the finger pulp with pelvic shielding. A circumferential regular stenosis of the low rectum was impassable for the colonoscope. Biopsies showed a signet-cell adenocarcinoma. Upper endoscopy and echo-endoscopy showed no evidence of gastric primary tumor, breasts, gallbladder and bladder were normal). The diagnosis of PRL was made. Pelvic MRI found a circumferential rigid thickened tubular lumen of the lower rectum, measuring 20 mm in maximum thickness, spread over 100 mm in height, with infiltration of the mesorectum, loss of interface of separation with the cervical uterine region and regional lymph nodes. No distant metastases were found on the thoraco abdominal CT. It was classified T4N1 M0. Tortuous oblong formations of the costo vertebral angles of the apical region have been found, most probably related to vascular malformations completing the triad of KTS. Neoadjuvant radio-chemotherapy was proposed. In the meantime, the patient was admitted to the emergency department for an occlusive syndrome, for which a colostomy was performed. The patient was not controlled on treatment and developed pleural metastases. She died 6 months after the diagnosis.

Discussion

99 % of linitis plastica occurs in the stomach while the rest occur in the breast, gall bladder, pancreas, urinary bladder and colon [5]. Primary colorectal linitis represents less than 0.1% of all colorectal tumors, 78% of them occur in the rectosigmoid segment [4]. Diagnosis is difficult since transanal biopsies may be too superficial [2]. Primary gastric linitis shouldn’t be missed and an upper endoscopy is systematic [2]. Typical imaging features include focal / circumferential wall thickening leading to luminal narrowing. Long segment involvement is common with lesions more than 10 cms not uncommonly found [6]. This tumor has a very poor prognosis and is most often metastatic at the time of diagnosis. Treatment options are not codified. Therefore we proposed with analogy to signet-cell stomach carcinoma, an adjuvant RCT. As far as we know, no case of PRL reported was associated to KTS. It is rare condition, with an unknown etiology and an incidence of approximately 1/100 000 live births [7]. 63% of patients with KLS have the manifestation of the complete triad (port-wine stain, varicose veins, and hypertrophy of soft tissues/bones)[8]. KTS could be either caused by embryonic mesodermal changes or sporadic polygenic mutations [2]. If there is a genetic background for PRL, the association we are reporting with KTS may open the discussion of common genes between these entities.
