Muscle metastases remain rare as a secondary localization for cancers in general and lung cancer in particular. They are discovered incidentally in most cases and in the advanced stages of cancer. We report the case of a 60-year-old man, followed for squamous cell carcinoma, who was found to have muscle metastases during the follow-up of associated muscle pain. This case highlights the existence of these metastases in lung squamous cell carcinoma, rare as it is, and requires particular attention from practitioners in the follow-up of patients to detect these cases as early as possible and improve patient survival. Computed Tomography (CT) remains an excellent exam for the detection of skeletal metastasis.

Chemotherapy may be responsible for central and/or peripheral neurotoxicity. These neurological complications are frequent but little known. Some molecules are more providers, responsible for acute or late complications, sometimes not reversible. Some manifestations such as acute encephalopathy and acute reversible encephalopathy are increasingly understood. We report here a case of acute ifosfamide-induced encephalopathy (EII) with brain damage resolved after discontinuation of this treatment in a 13-years-old child.

lynch syndrome (LS) is an autosomal dominant genetic disorder with incomplete penetration caused by a germline mutation in one of the genes of the deoxyribonucleic acid (DNA) mismatch repair system (MMR) namely: mutL homolog 1 (MLH1), mutS homolog 2 (MSH2), mutS homolog 6 (MHS6), post-meiotic segregation increased 1 homolog 2 (PMS2) or the EpCAM (Epithelial CellAdhesionMolecule) gene, which causes the inactivation of MSH2. Patients with this syndrome have a high relative risk of developing cancers at a young age, led by colorectal cancer (CRC) and endometrial cancer in females. The diagnosis is suspected when the patient’s personal and family history meets the Amsterdam or Bethesda criteria. It is guided by immunohistochemistry (IHC) and/or molecular biology that show loss of expression of one or more proteins of the MMR system and microsatellite instability on tumor DNA. In case of positive IHC and/or molecular biology, the patient should be referred to an oncogenetic consultation for a definitive diagnosis. We present the case of a 49-year-old patient who presented an anaemic syndrome in metrorrhagia. After a clinical, imaging, biological and anatomopathological examination, the diagnosis of LS was made.
