Primary liposarcoma of the sigmoid presenting as colonic intussusception - A case report.

Liposarcomas are malignant soft tissue neoplasms usually located in the retroperitoneum, head, neck and extremities. Although secondary invasion of the gastrointestinal tract by retroperitoneal sarcomas is frequent, primary involvement is uncommon. We report a young patient with Crohn's disease in remission presenting with intussusception of the colon due to a primary liposarcoma of the sigmoid.

Protein-losing gastropathy associated with cytomegalovirus infection in a child.

Protein-losing gastropathy is a rare entity. Unlike the disease in adults, it usually is benign and self-limited in children. The aetiological contribution of cytomegalovirus has been insufficiently documented and the immunological status of patients was rarely described in most reports.

When narrative medicine helps in the diagnosis of conjunctival melanoma - an exceptional case report.

Introduction: Conjunctival melanoma is a relatively rare ocular malignancy with substantial associated morbidity and mortality. It can arise in previously unblemished and unpigmented regions (approximately 10% of cases), from a preexisting nevus (approximately 20% of cases), or from the flat, spreading pigmentation of primary acquired melanosis with atypia (60-70% of cases), actually called conjunctival melanocytic intraepithelial neoplasia (C-MIN) with atypia (histopathologically more accurately term).

Purpose: The authors describe an extremely rare case of malignant conjunctival melanoma, with a long evolution, in a young black woman.

Mucoepidermoid carcinoma of the bulbar conjunctiva - an interventional case report.

Purpose: Mucoepidermoid carcinoma is a rare variant of squamous cell carcinoma of the conjunctiva. It appears more frequently in the elderly, it is more aggressive than squamous cell carcinoma, and it has a higher recurrence rate and higher incidence of intraocular and orbital invasion.

Methods: We report a case of a 74-year-old man who presented to the Emergency Department with a one month history of painful red left eye.
