Acetone compression improves lymph node yield and metastasis detection in colorectal cancer.

Lymph node status is one of the most important prognostic factors in colorectal cancer, and accurate pathological nodal staging and detection of lymph node metastases is crucial for determination of post-operative management. Current guidelines, including the TNM staging system and European Society for Medical Oncology (ESMO) guidelines, recommend examination of at least 12 lymph nodes. However, identification of an adequate number of lymph nodes can be challenging, especially in the setting of neoadjuvant treatment, which may reduce nodal size.

A cavernous hemangioma of the thyroid gland: First documentation by ultrasound of a rare pathology.

Hemangioma of the thyroid gland is an extremely rare condition. We report a case of a primary cavernous hemangioma in the left lobe of the thyroid gland in an 84-year-old woman. Ultrasound examination of the lesion showed an inhomogeneous and hypoechoic nodule that was well demarcated from the rest of the left lobe and hypovascular on color Doppler ultrasound.
