ABSTRACT
La mucopolisacaridosis tipo III B es una enfermedad de depósito lisosomal causada por la deficiencia de la enzima N-acetil-alfa-d-glucosaminidasa, implicada en el catabolismo del heparán sulfato, que produce su acúmulo en diversos tejidos. Se presenta a un paciente de 8 años, afectado de mucopolisacaridosis tipo III B, con historia de diarrea crónica y hallazgos endoscópicos e histológicos compatibles con linfangiectasia intestinal. Tras tratamiento dietético con restricción de ácidos grasos de cadena larga y rica en triglicéridos de cadena media, presentó mejoría clínica, mantenida hasta la actualidad.La patogenia de la diarrea crónica en pacientes con mucopolisacaridosis tipo III B es aún desconocida. Debe investigarse la presencia de linfangiectasia intestinal en estos pacientes e iniciar, en caso de confirmarse, un tratamiento dietético adecuado para mejorar así su calidad de vida.
Mucopolysaccharidosis type IIIB is a lysosomal storage disease caused by a deficiency of the N-acetyl-alpha-d-glucosaminidase enzyme involved in the catabolism of heparan sulfate, causing its accumulation in various tissues. We present an 8-year-old patient with mucopolysaccharidosis type IIIB, with a history of chronic diarrhea and endoscopic and histological findings compatible with intestinal lymphangiectasia. After a dietary treatment with a low-fat diet supplemented with medium-chain triglyceride, our patient presents clinical improvement until today. The pathogenesis of chronic diarrhea in patients with mucopolysaccharidosis type IIIB is still unknown. The presence of intestinal lymphangiectasia in these patients should be investigated, and appropriate dietary treatment should be initiated, if confirmed, to improve their quality of life.

A healthy 10-year-old boy presented with plaque-like cutaneous mucinosis (PCM) on his back. Cutaneous biopsy was followed by progressive resolution of the skin lesion. Pediatric PCM could differ clinically from the adult form. However, more cases are necessary to draw conclusions.

Adenosquamous carcinoma is a rare colorectal tumor with few cases described in the literature; no children have been reported. A 12-year-old-girl presented tenesmus, diarrhea, and iron deficiency anemia. Intestinal bowel disease was suspected, colonoscopy and biopsy were performed and the diagnosis was a squamous cell carcinoma. Chemoradiation therapy based on last colorectal cancer guidelines was started. Complete regression of the primary tumor was observed with lymph node progression. The pathology report of the lymphadenectomy revealed metastasis of adenosquamous carcinoma, although there was not any adenomatous component in the first biopsy. The patient presented progression with liver metastases, despite stable local disease due to response to first-line treatment of the squamous component.
