Department of Gastroenterology, Faculty of Medicine, University of Balamand, Beirut, Lebanon.
Article Synopsis
- Pseudomelanosis duodeni (PD) is a rare but benign condition characterized by dark speckles in the proximal duodenum, often linked to chronic diseases and certain medications, notably oral iron supplements.
- A 56-year-old woman with iron-deficiency anemia and a history of peptic ulcers was diagnosed with PD after an endoscopy revealed suspicious findings, confirmed by pathology showing iron-containing macrophages.
- The case highlights the connection between oral iron therapy and PD development, suggesting further research is needed on long-term outcomes and management strategies for this condition.

Article Synopsis
- A case of malignant acanthosis nigricans is presented involving a 30-year-old woman who had oral hyperplasia and skin pigmentation after eating seafood, despite previously being healthy and having allergies.
- Biopsy results confirmed papillary hyperplasia, and further testing revealed gastric cancer, identifying the acanthosis nigricans as a malignancy indicator.
- This case highlights that malignant acanthosis nigricans can occur in younger patients and underscores the need for thorough medical evaluations when oral lesions are present.

The most common site for metastases is the skin itself, although they can also occur in other organs, including the digestive tract, where the small intestine is the most frequently affected organ (2).

This study evaluates the effect of prolonged feeding with a high inclusion level of Spirulina, combined with peptidases, on broiler chicken's growth performance, digesta viscosity, carcass attributes and meat quality. The experiment involved 120 male broilers divided into 40 battery brooders, each housing 3 birds. Post 7-day acclimatisation with a corn and soybean-based diet, the birds were provided with one of four diets: a corn and soybean meal-based diet (CON), a mix incorporating 15% Spirulina (SP), a Spirulina-rich mix supplemented with 0.

It is also associated with extracolonic and extraintestinal manifestations that may overlap with the phenotype of familial adenomatous polyposis (FAP). Currently, there are discrepancies in the literature regarding whether certain phenotypes are truly associated with MAP.
