Dysphagia is the main presenting symptom, sometimes associated with regurgitation of undigested food, choking, cough, and, in advanced cases, oesophageal obstruction.
Viral antigens were detected in both axons and dendrites, which frequently presented many abnormal varicosities sometimes associated with closely adjacent immunolabeled glial cells (not illustrated), suggesting a possible interaction between diseased neurons and glia.
Coexisting RCC may present as an incidental microscopic finding sometimes associated with oncocytoma (hybrid tumour) (Fig. 14) or as a separate mass in the ipsilateral or contralateral kidney [27] (Fig. 11).
The presenting symptoms were bleeding on defecation, sometimes associated with anal pain or the sensation of an anal mass.
Most lesions present as a palpable swelling or mass, sometimes associated with pain or tenderness.
Overgrowth syndromes are rare genetic conditions which present as global or segmental hyperplasia and are sometimes associated with increased risk of malignancy.
Associated anomalies are present in 50%to70%0% of cases, and esophageal atresia is sometimes associated with chromosomopathies, especially Down's syndrome [12].
They present in utero as large, solid, infiltrative, unilateral renal masses [47], sometimes associated with polyhydramnios.
However, biomarkers reliant on early changes are inherently less useful than biomarkers present at baseline (because baseline markers do not warrant the initiation of therapy, sometimes associated with expense and toxicities, before measurement).
It is proved that very slightly perturbed minimal models can exhibit chaotic regimes, sometimes associated with chaotic strange attractors, as well as some of the bifurcations present in most of the differential equations models for similar physical circuit realizations.
