When narrative medicine helps in the diagnosis of conjunctival melanoma – an exceptional case report []

[english] 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. Results: Until now the patient has not shown any sign of relapse of this melanoma, after local excision.Conclusion: Conjunctival melanoma is a condition of concern because of its rarity and lethal potential. Advances in the understanding and management of this neoplasm have markedly reduced the mortality and possibly the morbidity associated with this malignancy. We observe that there are some cases of conjunctival melanoma that might be cured with only a local excision with posterior cryotherapy without more aggressive methods. The practice of narrative medicine brings new possibilities in the diagnosis and collection of classical history

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. Emergency resection confirmed the diagnosis. The patient remains in remission after five years. This represents the youngest diagnosis of liposarcoma to date and the first occurring in the sigmoid. We also highlight the concomitant diagnosis of Crohn's disease
