Abstract:
We present the case of a 60-year-old male patient, with refractory ulcers in the groin. Ultrasoundand CT showed a large vascularized tumor of the kidney with cystic parts and inhomogeneous dynamic behaviour. Histology demonstrated Pyoderma gangrenosum (ulcer) and well differentiated adenocarcinoma (kidney). Pyoderma gangrenosum appears as paraneoplastic manifestation in about 7% of cases, especially in lymphomas and tumors involving the digestive tract.Particularities of the case consisted in the accidental discovery of the renal tumor, in spite of the lack of urinary syndromes. The present case highlights the importance of tumor screening in patients with atypical antibiotic-refractory skin ulcers.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
