ABSTRACT
La presencia de "células en anillo de sello" en el tejido ovárico es el marcador histológico clásico del tumor de Krukenberg. Un adenocarcinoma metastásico altamente agresivo y de baja sobrevida. En cambio, los fibromas ováricos son tumores del estroma generalmente benignos. Presentamos un caso muy infrecuente de fibroma celular con presencia de células en anillo de sello y revisamos los criterios para el diagnóstico diferencial con el tumor de Krukenberg.
The presence of signet-ring cells in ovarian tissue is classically described as histological marker of Krukenberg tumor. It is highly aggressive metastatic adenocarcinoma with low survival. In contrast, ovarian fibroid is a stromal tumor usually benign. We present a very rare case of cellular fibroma with presence of signet-ring cells and we review the criteria for differential diagnosis of Krukenberg tumor.

Brown tumors are an uncommon manifestation of primary and secondary hyperparathyroidism. We report a 38 years old male consulting for generalized bone pain and prostration caused by multiple osteolytic lesions. Diagnostic work up disclosed a primary hyperparathyroidism secondary to a right parathyroid adenoma. The patient was subjected to a parathyroidectomy. After one year of follow up, symptoms have decreased considerably, laboratory parameters are normal and bone lesions are disappearing.

Enteric duplication cysts are uncommon congenital anomalies of the gastrointestinal tract that may arise anywhere along the digestive tract. They most frequently occur in the small intestine (terminal ileum) on its mesenteric border and rarely communicate with the digestive tract. Enteric duplication cysts are usually asymptomatic and diagnosed during childhood (first 2 years of life). We report a case of unusual presentation in an asymptomatic 21-year-old patient, who was diagnosed by contrast-enhanced multislice computed tomography.
Los quistes de duplicación intestinal, representan anomalías congénitas del tracto gastrointestinal poco frecuentes. Estos pueden surgir en cualquier localización a lo largo del tubo digestivo. La mayoría se desarrollan en el intestino delgado (Ileon terminal) en su borde mesentérico y rara vez presentan comunicación con el tracto digestivo. Usualmente, son diagnosticados durante la infancia (primeros 2 años de vida) donde suelen ser sintomáticos. Se expone un caso de presentación poco usual, en un paciente de 21 años, asintomático previamente, donde se llegó al diagnóstico a través de la tomografía computada multicorte contrastada.
