Background: Primary colorectal lymphoma represents a rare minority among the colonic neoplasms. Early diagnosis is often difficult because of unspecific symptoms, with subsequent delays in diagnosis and management. We describe a rare case of colonic lymphoma presenting with synchronous liver metastasis.

- Pyogenic granuloma (PG) is a type of growth that usually shows up on the skin, while intravenous pyogenic granuloma (IVPG) is similar but found in veins, often in the neck and arms.
- A rare case of IVPG was found in a 55-year-old woman who had stomach pain and was diagnosed using ultrasounds and CT scans, revealing a mass in her adrenal gland.
- The mass was successfully removed using a minimally invasive surgery, and tests showed it was indeed IVPG, highlighting how this condition can appear in unusual places in the body.
Background: Malignant perivascular epitheliod cell tumor (PEComa) is a very rare entity composed of distinctive perivascular epitheliod cells with variable immunoreactivity for melanocytic and muscle markers. At present this neoplasm does not have a known normal cellular counterpart and the natural history is often unpredictable. Up to now, few cases of PEComa have been described and treatment modalities are still controversial, particularly in advanced conditions.

Materials And Methods: Eighty-seven oncologic patients with FLLs underwent contrast-enhanced multidetector-row computed tomography (MDCT) and gadoxetic acid-enhanced magnetic resonance imaging (MRI). Two independent readers reviewed images for FLL detection and classification as benign or malignant without knowledge and after provision of clinical information.
